Deployment Method:

📝 NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Enter Your Internal Repository Url

(this should look similar to https://community.chocolatey.org/api/v2/)


2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade ludusavi -y --source="'INTERNAL REPO URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:


choco upgrade ludusavi -y --source="'INTERNAL REPO URL'" 
$exitCode = $LASTEXITCODE

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0
}

Exit $exitCode

Description

Version
License: MIT

Ludusavi is a tool for backing up your PC video game save data,
written in Rust.
It is cross-platform and supports multiple game stores.

Features

  • Ability to back up data from more than 7,000 games plus your own custom entries.
  • Backup and restore for Steam as well as other game libraries.
  • Preview of the backup/restore before actually performing it.
  • Both a graphical interface and command line interface for scripting.
    Tab completion is available for Bash, Fish, Zsh, PowerShell, and Elvish.
  • Support for:
    • Saves that are stored as files and in the Windows registry.
    • Proton saves with Steam.
    • Steam screenshots.
  • Available as a Playnite extension:
    https://github.com/mtkennerly/ludusavi-playnite

This tool uses the Ludusavi Manifest
for info on what to back up, and it will automatically download the latest version of
the primary manifest. The data is ultimately sourced from PCGamingWiki,
so please contribute any new or fixed data back to the wiki itself, and your
improvements will be incorporated into Ludusavi's data as well.

Demo

GUI

GUI demo of previewing a backup

CLI

CLI demo of previewing a backup

Requirements

Ludusavi is available for Windows, Linux, and Mac. However, your computer must
support one of these graphics systems: Vulkan, DirectX (11 or 12), or Metal.
(Experimental builds with OpenGL support are also available - give them a try
if the standard builds don't work on your system.)

Notes

When you first run Ludusavi, you may see a popup that says
"Windows protected your PC", because Windows does not recognize the program's
publisher. Click "more info" and then "run anyway" to start the program.

Configuration

Ludusavi stores its configuration in C:/Users/&<your-name&>/.config/ludusavi.
Alternatively, if you'd like Ludusavi to store its configuration in the same
place as the executable, then simply create a file called ludusavi.portable
in the directory that contains the executable file. You might want to do that
if you're going to run Ludusavi from a flash drive on multiple computers.

if you're using the GUI, then it will automatically update the config file
as needed, so you don't need to worry about its content. However, if you're
using the CLI exclusively, then you'll need to edit config.yaml yourself.

    this License, each Contributor hereby grants to You a perpetual,
    worldwide, non-exclusive, no-charge, royalty-free, irrevocable

    modifications, and in Source or Object form, provided that You
    meet the following conditions:

    (c) You must retain, in the Source form of any Derivative Works
    that You distribute, all copyright, patent, trademark, and
    attribution notices from the Source form of the Work,
    excluding those notices that do not pertain to any part of
    the Derivative Works; and
    
    (d) If the Work includes a "NOTICE" text file as part of its
    distribution, then any Derivative Works that You distribute must
    include a readable copy of the attribution notices contained
    within such NOTICE file, excluding those notices that do not
    pertain to any part of the Derivative Works, in at least one
    of the following places: within a NOTICE text file distributed
    as part of the Derivative Works; within the Source form or
    documentation, if provided along with the Derivative Works; or,
    within a display generated by the Derivative Works, if and
    wherever such third-party notices normally appear. The contents
    of the NOTICE file are for informational purposes only and
    do not modify the License. You may add Your own attribution
    notices within Derivative Works that You distribute, alongside
    or as an addendum to the NOTICE text from the Work, provided
    that such additional attribution notices cannot be construed
    as modifying the License.
    
    You may add Your own copyright statement to Your modifications and
    may provide additional or different license terms and conditions
    for use, reproduction, or distribution of Your modifications, or
    for any such Derivative Works as a whole, provided Your use,
    reproduction, and distribution of the Work otherwise complies with
    the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
    any Contribution intentionally submitted for inclusion in the Work
    by You to the Licensor shall be under the terms and conditions of
    this License, without any additional terms or conditions.

    the terms of any separate license agreement you may have executed
    with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
    names, trademarks, service marks, or product names of the Licensor,

    origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
    agreed to in writing, Licensor provides the Work (and each
    Contributor provides its Contributions) on an "AS IS" BASIS,
    WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
    implied, including, without limitation, any warranties or conditions
    of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
    PARTICULAR PURPOSE. You are solely responsible for determining the
    appropriateness of using or redistributing the Work and assume any
    risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
    whether in tort (including negligence), contract, or otherwise,
    unless required by applicable law (such as deliberate and grossly
    negligent acts) or agreed to in writing, shall any Contributor be
    liable to You for damages, including any direct, indirect, special,
    incidental, or consequential damages of any character arising as a
    result of this License or out of the use or inability to use the
    Work (including but not limited to damages for loss of goodwill,
    work stoppage, computer failure or malfunction, or any and all
    other commercial damages or losses), even if such Contributor
    has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
    the Work or Derivative Works thereof, You may choose to offer,
    and charge a fee for, acceptance of support, warranty, indemnity,
    or other liability obligations and/or rights consistent with this
    License. However, in accepting such obligations, You may act only
    on Your own behalf and on Your sole responsibility, not on behalf
    of any other Contributor, and only if You agree to indemnify,
    defend, and hold each Contributor harmless for any liability
    incurred by, or claims asserted against, such Contributor by reason
    of your accepting any such warranty or additional liability.

       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including

          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable

          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate

              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one

              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify

          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,

          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor

       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the

          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained

          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or

          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify

          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the

       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor

          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.

       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,

       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain

       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
    1. Definitions.
    
       "License" shall mean the terms and conditions for use, reproduction,
       and distribution as defined by Sections 1 through 9 of this document.
    
       "Licensor" shall mean the copyright owner or entity authorized by
       the copyright owner that is granting the License.
    
       "Legal Entity" shall mean the union of the acting entity and all
       other entities that control, are controlled by, or are under common
       control with that entity. For the purposes of this definition,
       "control" means (i) the power, direct or indirect, to cause the
       direction or management of such entity, whether by contract or
       otherwise, or (ii) ownership of fifty percent (50%) or more of the
       outstanding shares, or (iii) beneficial ownership of such entity.
    
       "You" (or "Your") shall mean an individual or Legal Entity
       exercising permissions granted by this License.
    
       "Source" form shall mean the preferred form for making modifications,
       including but not limited to software source code, documentation
       source, and configuration files.
    
       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but

       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.
    
    END OF TERMS AND CONDITIONS

          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications

          of this License, Derivative Works shall not include works that remain

          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including

          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.
    
       3. Grant of Patent License. Subject to the terms and conditions of

          Contribution(s) alone or by combination of their Contribution(s)

          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.
    
       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without

              stating that You changed the files; and
    
          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.
    
       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.
    
       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.

       TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
       1. Definitions.
    
          "License" shall mean the terms and conditions for use, reproduction,
          and distribution as defined by Sections 1 through 9 of this document.
    
          "Licensor" shall mean the copyright owner or entity authorized by
          the copyright owner that is granting the License.
    
          "Legal Entity" shall mean the union of the acting entity and all
          other entities that control, are controlled by, or are under common
          control with that entity. For the purposes of this definition,
          "control" means (i) the power, direct or indirect, to cause the
          direction or management of such entity, whether by contract or
          otherwise, or (ii) ownership of fifty percent (50%) or more of the
          outstanding shares, or (iii) beneficial ownership of such entity.
    
          "You" (or "Your") shall mean an individual or Legal Entity
          exercising permissions granted by this License.
    
          "Source" form shall mean the preferred form for making modifications,

          source, and configuration files.
    
          "Object" form shall mean any form resulting from mechanical
          transformation or translation of a Source form, including but
          not limited to compiled object code, generated documentation,
          and conversions to other media types.
    
          "Work" shall mean the work of authorship, whether in Source or
          Object form, made available under the License, as indicated by a
          copyright notice that is included in or attached to the work
          (an example is provided in the Appendix below).
    
          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions
          to that Work or Derivative Works thereof, that is intentionally
          submitted to Licensor for inclusion in the Work by the copyright owner
          or by an individual or Legal Entity authorized to submit on behalf of
          the copyright owner. For the purposes of this definition, "submitted"
          means any form of electronic, verbal, or written communication sent
          to the Licensor or its representatives, including but not limited to
          communication on electronic mailing lists, source code control systems,
          and issue tracking systems that are managed by, or on behalf of, the
          Licensor for the purpose of discussing and improving the Work, but
          excluding communication that is conspicuously marked or otherwise
          designated in writing by the copyright owner as "Not a Contribution."
    
          "Contributor" shall mean Licensor and any individual or Legal Entity
          on behalf of whom a Contribution has been received by Licensor and
          subsequently incorporated within the Work.
    
       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.
    
       3. Grant of Patent License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.
    
       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You
          meet the following conditions:
    
          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and
    
          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and
    
          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.
    
       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.
    
       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.
    
       END OF TERMS AND CONDITIONS

       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,

       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work

       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain

       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.

       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You

           excluding those notices that do not pertain to any part of
           the Derivative Works; and

           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed

           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or

       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

 * constant_time_eq 0.1.5 under the terms of CC0-1.0:

    Creative Commons Legal Code
    
    CC0 1.0 Universal
    
        CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
        LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
        ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
        INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
        REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
        PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
        THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
        HEREUNDER.
    
    Statement of Purpose
    
    The laws of most jurisdictions throughout the world automatically confer
    exclusive Copyright and Related Rights (defined below) upon the creator
    and subsequent owner(s) (each and all, an "owner") of an original work of
    authorship and/or a database (each, a "Work").
    
    Certain owners wish to permanently relinquish those rights to a Work for
    the purpose of contributing to a commons of creative, cultural and
    scientific works ("Commons") that the public can reliably and without fear
    of later claims of infringement build upon, modify, incorporate in other
    works, reuse and redistribute as freely as possible in any form whatsoever
    and for any purposes, including without limitation commercial purposes.
    These owners may contribute to the Commons to promote the ideal of a free
    culture and the further production of creative, cultural and scientific
    works, or to gain reputation or greater distribution for their Work in
    part through the use and efforts of others.
    
    For these and/or other purposes and motivations, and without any
    expectation of additional consideration or compensation, the person
    associating CC0 with a Work (the "Affirmer"), to the extent that he or she
    is an owner of Copyright and Related Rights in the Work, voluntarily
    elects to apply CC0 to the Work and publicly distribute the Work under its
    terms, with knowledge of his or her Copyright and Related Rights in the
    Work and the meaning and intended legal effect of CC0 on those rights.
    
    1. Copyright and Related Rights. A Work made available under CC0 may be
    protected by copyright and related or neighboring rights ("Copyright and
    Related Rights"). Copyright and Related Rights include, but are not
    limited to, the following:
    
      i. the right to reproduce, adapt, distribute, perform, display,
         communicate, and translate a Work;
     ii. moral rights retained by the original author(s) and/or performer(s);
    iii. publicity and privacy rights pertaining to a person's image or
         likeness depicted in a Work;
     iv. rights protecting against unfair competition in regards to a Work,
         subject to the limitations in paragraph 4(a), below;
      v. rights protecting the extraction, dissemination, use and reuse of data
         in a Work;
     vi. database rights (such as those arising under Directive 96/9/EC of the
         European Parliament and of the Council of 11 March 1996 on the legal
         protection of databases, and under any national implementation
         thereof, including any amended or successor version of such
         directive); and
    vii. other similar, equivalent or corresponding rights throughout the
         world based on applicable law or treaty, and any national
         implementations thereof.
    
    2. Waiver. To the greatest extent permitted by, but not in contravention
    of, applicable law, Affirmer hereby overtly, fully, permanently,
    irrevocably and unconditionally waives, abandons, and surrenders all of
    Affirmer's Copyright and Related Rights and associated claims and causes
    of action, whether now known or unknown (including existing as well as
    future claims and causes of action), in the Work (i) in all territories
    worldwide, (ii) for the maximum duration provided by applicable law or
    treaty (including future time extensions), (iii) in any current or future
    medium and for any number of copies, and (iv) for any purpose whatsoever,
    including without limitation commercial, advertising or promotional
    purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
    member of the public at large and to the detriment of Affirmer's heirs and
    successors, fully intending that such Waiver shall not be subject to
    revocation, rescission, cancellation, termination, or any other legal or
    equitable action to disrupt the quiet enjoyment of the Work by the public
    as contemplated by Affirmer's express Statement of Purpose.
    
    3. Public License Fallback. Should any part of the Waiver for any reason
    be judged legally invalid or ineffective under applicable law, then the
    Waiver shall be preserved to the maximum extent permitted taking into
    account Affirmer's express Statement of Purpose. In addition, to the
    extent the Waiver is so judged Affirmer hereby grants to each affected
    person a royalty-free, non transferable, non sublicensable, non exclusive,
    irrevocable and unconditional license to exercise Affirmer's Copyright and
    Related Rights in the Work (i) in all territories worldwide, (ii) for the
    maximum duration provided by applicable law or treaty (including future
    time extensions), (iii) in any current or future medium and for any number
    of copies, and (iv) for any purpose whatsoever, including without
    limitation commercial, advertising or promotional purposes (the
    "License"). The License shall be deemed effective as of the date CC0 was
    applied by Affirmer to the Work. Should any part of the License for any
    reason be judged legally invalid or ineffective under applicable law, such
    partial invalidity or ineffectiveness shall not invalidate the remainder
    of the License, and in such case Affirmer hereby affirms that he or she
    will not (i) exercise any of his or her remaining Copyright and Related
    Rights in the Work or (ii) assert any associated claims and causes of
    action with respect to the Work, in either case contrary to Affirmer's
    express Statement of Purpose.
    
    4. Limitations and Disclaimers.
    
     a. No trademark or patent rights held by Affirmer are waived, abandoned,
        surrendered, licensed or otherwise affected by this document.
     b. Affirmer offers the Work as-is and makes no representations or
        warranties of any kind concerning the Work, express, implied,
        statutory or otherwise, including without limitation warranties of
        title, merchantability, fitness for a particular purpose, non
        infringement, or the absence of latent or other defects, accuracy, or
        the present or absence of errors, whether or not discoverable, all to
        the greatest extent permissible under applicable law.
     c. Affirmer disclaims responsibility for clearing rights of other persons
        that may apply to the Work or any use thereof, including without
        limitation any person's Copyright and Related Rights in the Work.
        Further, Affirmer disclaims responsibility for obtaining any necessary
        consents, permissions or other rights required for any use of the
        Work.
     d. Affirmer understands and acknowledges that Creative Commons is not a
        party to this document and has no duty or obligation with respect to
        this CC0 or use of the Work.

       TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
       1. Definitions.
    
          "License" shall mean the terms and conditions for use, reproduction,
          and distribution as defined by Sections 1 through 9 of this document.
    
          "Licensor" shall mean the copyright owner or entity authorized by
          the copyright owner that is granting the License.
    
          "Legal Entity" shall mean the union of the acting entity and all
          other entities that control, are controlled by, or are under common
          control with that entity. For the purposes of this definition,
          "control" means (i) the power, direct or indirect, to cause the
          direction or management of such entity, whether by contract or
          otherwise, or (ii) ownership of fifty percent (50%) or more of the
          outstanding shares, or (iii) beneficial ownership of such entity.
    
          "You" (or "Your") shall mean an individual or Legal Entity
          exercising permissions granted by this License.
    
          "Source" form shall mean the preferred form for making modifications,
          including but not limited to software source code, documentation
          source, and configuration files.
    
          "Object" form shall mean any form resulting from mechanical
          transformation or translation of a Source form, including but
          not limited to compiled object code, generated documentation,
          and conversions to other media types.
    
          "Work" shall mean the work of authorship, whether in Source or
          Object form, made available under the License, as indicated by a
          copyright notice that is included in or attached to the work
          (an example is provided in the Appendix below).
    
          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions
          to that Work or Derivative Works thereof, that is intentionally
          submitted to Licensor for inclusion in the Work by the copyright owner
          or by an individual or Legal Entity authorized to submit on behalf of
          the copyright owner. For the purposes of this definition, "submitted"
          means any form of electronic, verbal, or written communication sent
          to the Licensor or its representatives, including but not limited to
          communication on electronic mailing lists, source code control systems,
          and issue tracking systems that are managed by, or on behalf of, the
          Licensor for the purpose of discussing and improving the Work, but
          excluding communication that is conspicuously marked or otherwise
          designated in writing by the copyright owner as "Not a Contribution."
    
          "Contributor" shall mean Licensor and any individual or Legal Entity
          on behalf of whom a Contribution has been received by Licensor and
          subsequently incorporated within the Work.
    
       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.
    
       3. Grant of Patent License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.
    
       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You
          meet the following conditions:
    
          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and
    
          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and
    
          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.
    
       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.
    
       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.
    
       END OF TERMS AND CONDITIONS
    
       APPENDIX: How to apply the Apache License to your work.
    
          To apply the Apache License to your work, attach the following
          boilerplate notice, with the fields enclosed by brackets "{}"
          replaced with your own identifying information. (Don't include
          the brackets!)  The text should be enclosed in the appropriate
          comment syntax for the file format. We also recommend that a
          file or class name and description of purpose be included on the
          same "printed page" as the copyright notice for easier
          identification within third-party archives.

       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain

       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,

       "Contributor" shall mean Licensor and any individual or Legal Entity

       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions

       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       form, that is based on (or derived from) the Work and for which the

       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,

          Object form, made available under the License, as indicated by a
          copyright notice that is included in or attached to the work
          (an example is provided in the Appendix below).
    
          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions
          to that Work or Derivative Works thereof, that is intentionally
          submitted to Licensor for inclusion in the Work by the copyright owner
          or by an individual or Legal Entity authorized to submit on behalf of
          the copyright owner. For the purposes of this definition, "submitted"
          means any form of electronic, verbal, or written communication sent
          to the Licensor or its representatives, including but not limited to
          communication on electronic mailing lists, source code control systems,
          and issue tracking systems that are managed by, or on behalf of, the
          Licensor for the purpose of discussing and improving the Work, but
          excluding communication that is conspicuously marked or otherwise
          designated in writing by the copyright owner as "Not a Contribution."
    
          "Contributor" shall mean Licensor and any individual or Legal Entity
          on behalf of whom a Contribution has been received by Licensor and
          subsequently incorporated within the Work.
    
       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.
    
       3. Grant of Patent License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.
    
       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You
          meet the following conditions:
    
          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and
    
          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and
    
          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.
    
       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.
    
       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.

       source, and configuration files.
    
       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,

       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions

       communication on electronic mailing lists, source code control systems,

       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain

       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,

       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,

       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain

       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions

       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,

       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,

       Licensor for the purpose of discussing and improving the Work, but

       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a

       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing

    the notice requirements in Section 3.4).
    
    2.4. Subsequent Licenses
    
    No Contributor makes additional grants as a result of Your choice to
    distribute the Covered Software under a subsequent version of this
    License (see Section 10.2) or under the terms of a Secondary License (if
    permitted under the terms of Section 3.3).
    
    2.5. Representation
    
    Each Contributor represents that the Contributor believes its
    Contributions are its original creation(s) or it has sufficient rights
    to grant the rights to its Contributions conveyed by this License.
    
    2.6. Fair Use
    
    This License is not intended to limit any rights You have under
    applicable copyright doctrines of fair use, fair dealing, or other
    equivalents.
    
    2.7. Conditions
    
    Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
    in Section 2.1.
    
    3. Responsibilities
    -------------------
    
    3.1. Distribution of Source Form
    
    All distribution of Covered Software in Source Code Form, including any
    Modifications that You create or to which You contribute, must be under
    the terms of this License. You must inform recipients that the Source
    Code Form of the Covered Software is governed by the terms of this
    License, and how they can obtain a copy of this License. You may not
    attempt to alter or restrict the recipients' rights in the Source Code
    Form.
    
    3.2. Distribution of Executable Form
    
    If You distribute Covered Software in Executable Form then:
    
    (a) such Covered Software must also be made available in Source Code
        Form, as described in Section 3.1, and You must inform recipients of
        the Executable Form how they can obtain a copy of such Source Code
        Form by reasonable means in a timely manner, at a charge no more
        than the cost of distribution to the recipient; and
    
    (b) You may distribute such Executable Form under the terms of this
        License, or sublicense it under different terms, provided that the
        license for the Executable Form does not attempt to limit or alter
        the recipients' rights in the Source Code Form under this License.
    
    3.3. Distribution of a Larger Work
    
    You may create and distribute a Larger Work under terms of Your choice,
    provided that You also comply with the requirements of this License for
    the Covered Software. If the Larger Work is a combination of Covered
    Software with a work governed by one or more Secondary Licenses, and the
    Covered Software is not Incompatible With Secondary Licenses, this
    License permits You to additionally distribute such Covered Software
    under the terms of such Secondary License(s), so that the recipient of
    the Larger Work may, at their option, further distribute the Covered
    Software under the terms of either this License or such Secondary
    License(s).
    
    3.4. Notices
    
    You may not remove or alter the substance of any license notices
    (including copyright notices, patent notices, disclaimers of warranty,
    or limitations of liability) contained within the Source Code Form of
    the Covered Software, except that You may alter any license notices to
    the extent required to remedy known factual inaccuracies.
    
    3.5. Application of Additional Terms
    
    You may choose to offer, and to charge a fee for, warranty, support,
    indemnity or liability obligations to one or more recipients of Covered
    Software. However, You may do so only on Your own behalf, and not on
    behalf of any Contributor. You must make it absolutely clear that any
    such warranty, support, indemnity, or liability obligation is offered by
    You alone, and You hereby agree to indemnify every Contributor for any
    liability incurred by such Contributor as a result of warranty, support,
    indemnity or liability terms You offer. You may include additional
    disclaimers of warranty and limitations of liability specific to any
    jurisdiction.
    
    4. Inability to Comply Due to Statute or Regulation
    ---------------------------------------------------
    
    If it is impossible for You to comply with any of the terms of this
    License with respect to some or all of the Covered Software due to
    statute, judicial order, or regulation then You must: (a) comply with
    the terms of this License to the maximum extent possible; and (b)
    describe the limitations and the code they affect. Such description must
    be placed in a text file included with all distributions of the Covered
    Software under this License. Except to the extent prohibited by statute
    or regulation, such description must be sufficiently detailed for a
    recipient of ordinary skill to be able to understand it.
    
    5. Termination
    --------------
    
    5.1. The rights granted under this License will terminate automatically
    if You fail to comply with any of its terms. However, if You become
    compliant, then the rights granted under this License from a particular
    Contributor are reinstated (a) provisionally, unless and until such
    Contributor explicitly and finally terminates Your grants, and (b) on an
    ongoing basis, if such Contributor fails to notify You of the
    non-compliance by some reasonable means prior to 60 days after You have
    come back into compliance. Moreover, Your grants from a particular
    Contributor are reinstated on an ongoing basis if such Contributor
    notifies You of the non-compliance by some reasonable means, this is the
    first time You have received notice of non-compliance with this License
    from such Contributor, and You become compliant prior to 30 days after
    Your receipt of the notice.
    
    5.2. If You initiate litigation against any entity by asserting a patent
    infringement claim (excluding declaratory judgment actions,
    counter-claims, and cross-claims) alleging that a Contributor Version
    directly or indirectly infringes any patent, then the rights granted to
    You by any and all Contributors for the Covered Software under Section
    2.1 of this License shall terminate.
    
    5.3. In the event of termination under Sections 5.1 or 5.2 above, all
    end user license agreements (excluding distributors and resellers) which
    have been validly granted by You or Your distributors under this License
    prior to termination shall survive termination.

    *  Covered Software is free of defects, merchantable, fit for a        *
    *  particular purpose or non-infringing. The entire risk as to the     *
    *  quality and performance of the Covered Software is with You.        *
    *  Should any Covered Software prove defective in any respect, You     *
    *  (not any Contributor) assume the cost of any necessary servicing,   *
    *  repair, or correction. This disclaimer of warranty constitutes an   *

    *                                                                      *

    *  special, incidental, or consequential damages of any character      *
    *  including, without limitation, damages for lost profits, loss of    *
    *  goodwill, work stoppage, computer failure or malfunction, or any    *
    *  and all other commercial damages or losses, even if such party      *

    *                                                                      *
    ************************************************************************
    
    8. Litigation
    -------------
    
    Any litigation relating to this License may be brought only in the
    courts of a jurisdiction where the defendant maintains its principal
    place of business and such litigation shall be governed by laws of that
    jurisdiction, without reference to its conflict-of-law provisions.
    Nothing in this Section shall prevent a party's ability to bring
    cross-claims or counter-claims.
    
    9. Miscellaneous
    ----------------
    
    This License represents the complete agreement concerning the subject
    matter hereof. If any provision of this License is held to be
    unenforceable, such provision shall be reformed only to the extent
    necessary to make it enforceable. Any law or regulation which provides
    that the language of a contract shall be construed against the drafter
    shall not be used to construe this License against a Contributor.
    
    10. Versions of the License
    ---------------------------
    
    10.1. New Versions
    
    Mozilla Foundation is the license steward. Except as provided in Section
    10.3, no one other than the license steward has the right to modify or
    publish new versions of this License. Each version will be given a
    distinguishing version number.
    
    10.2. Effect of New Versions

    or under the terms of any subsequent version published by the license
    steward.
    
    10.3. Modified Versions
    
    If you create software not governed by this License, and you want to
    create a new license for such software, you may create and use a
    modified version of this License if you rename the license and remove
    any references to the name of the license steward (except to note that
    such modified license differs from this License).
    
    10.4. Distributing Source Code Form that is Incompatible With Secondary
    Licenses
    
    If You choose to distribute Source Code Form that is Incompatible With
    Secondary Licenses under the terms of this version of the License, the

       source, and configuration files.
    
       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.
    
    END OF TERMS AND CONDITIONS

    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
    1. Definitions.
    
       "License" shall mean the terms and conditions for use, reproduction,
       and distribution as defined by Sections 1 through 9 of this document.
    
       "Licensor" shall mean the copyright owner or entity authorized by
       the copyright owner that is granting the License.
    
       "Legal Entity" shall mean the union of the acting entity and all
       other entities that control, are controlled by, or are under common
       control with that entity. For the purposes of this definition,
       "control" means (i) the power, direct or indirect, to cause the
       direction or management of such entity, whether by contract or
       otherwise, or (ii) ownership of fifty percent (50%) or more of the

       "You" (or "Your") shall mean an individual or Legal Entity
       exercising permissions granted by this License.
    
       "Source" form shall mean the preferred form for making modifications,
       including but not limited to software source code, documentation
       source, and configuration files.
    
       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
       1. Definitions.
    
          "License" shall mean the terms and conditions for use, reproduction,
          and distribution as defined by Sections 1 through 9 of this document.
    
          "Licensor" shall mean the copyright owner or entity authorized by

          "Legal Entity" shall mean the union of the acting entity and all
          other entities that control, are controlled by, or are under common
          control with that entity. For the purposes of this definition,

          direction or management of such entity, whether by contract or
          otherwise, or (ii) ownership of fifty percent (50%) or more of the
          outstanding shares, or (iii) beneficial ownership of such entity.

          transformation or translation of a Source form, including but
          not limited to compiled object code, generated documentation,
          and conversions to other media types.
    
          "Work" shall mean the work of authorship, whether in Source or
          Object form, made available under the License, as indicated by a
          copyright notice that is included in or attached to the work
          (an example is provided in the Appendix below).
    
          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions
          to that Work or Derivative Works thereof, that is intentionally
          submitted to Licensor for inclusion in the Work by the copyright owner
          or by an individual or Legal Entity authorized to submit on behalf of
          the copyright owner. For the purposes of this definition, "submitted"
          means any form of electronic, verbal, or written communication sent
          to the Licensor or its representatives, including but not limited to
          communication on electronic mailing lists, source code control systems,

          Licensor for the purpose of discussing and improving the Work, but
          excluding communication that is conspicuously marked or otherwise
          designated in writing by the copyright owner as "Not a Contribution."
    
          "Contributor" shall mean Licensor and any individual or Legal Entity
          on behalf of whom a Contribution has been received by Licensor and
          subsequently incorporated within the Work.
    
       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.
    
       3. Grant of Patent License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.
    
       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You
          meet the following conditions:
    
          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and
    
          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and
    
          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.
    
       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.
    
       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.
    
       END OF TERMS AND CONDITIONS

          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including

          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.
    
       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without

              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.
    
       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.
    
       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.

       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
       1. Definitions.
    
          "License" shall mean the terms and conditions for use, reproduction,
          and distribution as defined by Sections 1 through 9 of this document.
    
          "Licensor" shall mean the copyright owner or entity authorized by
          the copyright owner that is granting the License.
    
          "Legal Entity" shall mean the union of the acting entity and all
          other entities that control, are controlled by, or are under common
          control with that entity. For the purposes of this definition,
          "control" means (i) the power, direct or indirect, to cause the
          direction or management of such entity, whether by contract or
          otherwise, or (ii) ownership of fifty percent (50%) or more of the
          outstanding shares, or (iii) beneficial ownership of such entity.
    
          "You" (or "Your") shall mean an individual or Legal Entity
          exercising permissions granted by this License.
    
          "Source" form shall mean the preferred form for making modifications,
          including but not limited to software source code, documentation
          source, and configuration files.
    
          "Object" form shall mean any form resulting from mechanical
          transformation or translation of a Source form, including but
          not limited to compiled object code, generated documentation,
          and conversions to other media types.
    
          "Work" shall mean the work of authorship, whether in Source or
          Object form, made available under the License, as indicated by a
          copyright notice that is included in or attached to the work
          (an example is provided in the Appendix below).
    
          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions
          to that Work or Derivative Works thereof, that is intentionally
          submitted to Licensor for inclusion in the Work by the copyright owner
          or by an individual or Legal Entity authorized to submit on behalf of
          the copyright owner. For the purposes of this definition, "submitted"
          means any form of electronic, verbal, or written communication sent
          to the Licensor or its representatives, including but not limited to
          communication on electronic mailing lists, source code control systems,
          and issue tracking systems that are managed by, or on behalf of, the
          Licensor for the purpose of discussing and improving the Work, but
          excluding communication that is conspicuously marked or otherwise
          designated in writing by the copyright owner as "Not a Contribution."
    
          "Contributor" shall mean Licensor and any individual or Legal Entity
          on behalf of whom a Contribution has been received by Licensor and
          subsequently incorporated within the Work.
    
       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.
    
       3. Grant of Patent License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.
    
       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You
          meet the following conditions:
    
          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and
    
          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and
    
          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.
    
       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.
    
       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.

          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the

          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions

          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.
    
       3. Grant of Patent License. Subject to the terms and conditions of

          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate

              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one

              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,

       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.

       "Contributor" shall mean Licensor and any individual or Legal Entity

       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,

       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and

       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions

       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.

       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,

       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You

           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions

       Licensor for the purpose of discussing and improving the Work, but

       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,

       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You

           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       incidental, or consequential damages of any character arising as a

       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions

       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but

       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and

           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       source, and configuration files.
    
       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally

       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but

       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and

           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
       1. Definitions.
    
          "License" shall mean the terms and conditions for use, reproduction,

          control with that entity. For the purposes of this definition,

          direction or management of such entity, whether by contract or
          otherwise, or (ii) ownership of fifty percent (50%) or more of the
          outstanding shares, or (iii) beneficial ownership of such entity.

          transformation or translation of a Source form, including but
          not limited to compiled object code, generated documentation,

          "Work" shall mean the work of authorship, whether in Source or
          Object form, made available under the License, as indicated by a
          copyright notice that is included in or attached to the work
          (an example is provided in the Appendix below).
    
          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions

          submitted to Licensor for inclusion in the Work by the copyright owner
          or by an individual or Legal Entity authorized to submit on behalf of
          the copyright owner. For the purposes of this definition, "submitted"
          means any form of electronic, verbal, or written communication sent
          to the Licensor or its representatives, including but not limited to
          communication on electronic mailing lists, source code control systems,

          "Contributor" shall mean Licensor and any individual or Legal Entity
          on behalf of whom a Contribution has been received by Licensor and
          subsequently incorporated within the Work.
    
       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.
    
       3. Grant of Patent License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.
    
       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You
          meet the following conditions:
    
          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and
    
          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and
    
          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.
    
       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.
    
       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.
    
       END OF TERMS AND CONDITIONS

       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
    1. Definitions.
    
       "License" shall mean the terms and conditions for use, reproduction,
       and distribution as defined by Sections 1 through 9 of this document.
    
       "Licensor" shall mean the copyright owner or entity authorized by
       the copyright owner that is granting the License.
    
       "Legal Entity" shall mean the union of the acting entity and all

       source, and configuration files.
    
       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
    1. Definitions.
    
       "License" shall mean the terms and conditions for use, reproduction,
       and distribution as defined by Sections 1 through 9 of this document.
    
       "Licensor" shall mean the copyright owner or entity authorized by
       the copyright owner that is granting the License.
    
       "Legal Entity" shall mean the union of the acting entity and all

       direction or management of such entity, whether by contract or
       otherwise, or (ii) ownership of fifty percent (50%) or more of the

       "Source" form shall mean the preferred form for making modifications,
       including but not limited to software source code, documentation
       source, and configuration files.
    
       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

       TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
       1. Definitions.
    
          "License" shall mean the terms and conditions for use, reproduction,

          direction or management of such entity, whether by contract or
          otherwise, or (ii) ownership of fifty percent (50%) or more of the

          (an example is provided in the Appendix below).
    
          "Derivative Works" shall mean any work, whether in Source or Object
          form, that is based on (or derived from) the Work and for which the
          editorial revisions, annotations, elaborations, or other modifications
          represent, as a whole, an original work of authorship. For the purposes
          of this License, Derivative Works shall not include works that remain
          separable from, or merely link (or bind by name) to the interfaces of,
          the Work and Derivative Works thereof.
    
          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions

          the copyright owner. For the purposes of this definition, "submitted"
          means any form of electronic, verbal, or written communication sent
          to the Licensor or its representatives, including but not limited to
          communication on electronic mailing lists, source code control systems,

       2. Grant of Copyright License. Subject to the terms and conditions of
          this License, each Contributor hereby grants to You a perpetual,
          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
          copyright license to reproduce, prepare Derivative Works of,
          publicly display, publicly perform, sublicense, and distribute the
          Work and such Derivative Works in Source or Object form.
    
       3. Grant of Patent License. Subject to the terms and conditions of

          (except as stated in this section) patent license to make, have made,
          use, offer to sell, sell, import, and otherwise transfer the Work,
          where such license applies only to those patent claims licensable
          by such Contributor that are necessarily infringed by their
          Contribution(s) alone or by combination of their Contribution(s)
          with the Work to which such Contribution(s) was submitted. If You
          institute patent litigation against any entity (including a
          cross-claim or counterclaim in a lawsuit) alleging that the Work
          or a Contribution incorporated within the Work constitutes direct
          or contributory patent infringement, then any patent licenses
          granted to You under this License for that Work shall terminate
          as of the date such litigation is filed.
    
       4. Redistribution. You may reproduce and distribute copies of the
          Work or Derivative Works thereof in any medium, with or without
          modifications, and in Source or Object form, provided that You

          (a) You must give any other recipients of the Work or
              Derivative Works a copy of this License; and
    
          (b) You must cause any modified files to carry prominent notices
              stating that You changed the files; and
    
          (c) You must retain, in the Source form of any Derivative Works
              that You distribute, all copyright, patent, trademark, and
              attribution notices from the Source form of the Work,
              excluding those notices that do not pertain to any part of
              the Derivative Works; and
    
          (d) If the Work includes a "NOTICE" text file as part of its
              distribution, then any Derivative Works that You distribute must
              include a readable copy of the attribution notices contained
              within such NOTICE file, excluding those notices that do not
              pertain to any part of the Derivative Works, in at least one
              of the following places: within a NOTICE text file distributed
              as part of the Derivative Works; within the Source form or
              documentation, if provided along with the Derivative Works; or,
              within a display generated by the Derivative Works, if and
              wherever such third-party notices normally appear. The contents
              of the NOTICE file are for informational purposes only and
              do not modify the License. You may add Your own attribution
              notices within Derivative Works that You distribute, alongside
              or as an addendum to the NOTICE text from the Work, provided
              that such additional attribution notices cannot be construed
              as modifying the License.
    
          You may add Your own copyright statement to Your modifications and
          may provide additional or different license terms and conditions
          for use, reproduction, or distribution of Your modifications, or
          for any such Derivative Works as a whole, provided Your use,
          reproduction, and distribution of the Work otherwise complies with
          the conditions stated in this License.
    
       5. Submission of Contributions. Unless You explicitly state otherwise,
          any Contribution intentionally submitted for inclusion in the Work
          by You to the Licensor shall be under the terms and conditions of
          this License, without any additional terms or conditions.
          Notwithstanding the above, nothing herein shall supersede or modify
          the terms of any separate license agreement you may have executed
          with Licensor regarding such Contributions.
    
       6. Trademarks. This License does not grant permission to use the trade
          names, trademarks, service marks, or product names of the Licensor,
          except as required for reasonable and customary use in describing the
          origin of the Work and reproducing the content of the NOTICE file.
    
       7. Disclaimer of Warranty. Unless required by applicable law or
          agreed to in writing, Licensor provides the Work (and each
          Contributor provides its Contributions) on an "AS IS" BASIS,
          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
          implied, including, without limitation, any warranties or conditions
          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
          PARTICULAR PURPOSE. You are solely responsible for determining the
          appropriateness of using or redistributing the Work and assume any
          risks associated with Your exercise of permissions under this License.
    
       8. Limitation of Liability. In no event and under no legal theory,
          whether in tort (including negligence), contract, or otherwise,
          unless required by applicable law (such as deliberate and grossly
          negligent acts) or agreed to in writing, shall any Contributor be
          liable to You for damages, including any direct, indirect, special,
          incidental, or consequential damages of any character arising as a
          result of this License or out of the use or inability to use the
          Work (including but not limited to damages for loss of goodwill,
          work stoppage, computer failure or malfunction, or any and all
          other commercial damages or losses), even if such Contributor
          has been advised of the possibility of such damages.
    
       9. Accepting Warranty or Additional Liability. While redistributing
          the Work or Derivative Works thereof, You may choose to offer,
          and charge a fee for, acceptance of support, warranty, indemnity,
          or other liability obligations and/or rights consistent with this
          License. However, in accepting such obligations, You may act only
          on Your own behalf and on Your sole responsibility, not on behalf
          of any other Contributor, and only if You agree to indemnify,
          defend, and hold each Contributor harmless for any liability
          incurred by, or claims asserted against, such Contributor by reason
          of your accepting any such warranty or additional liability.

       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. However, in accepting such obligations, You may act only
       on Your own behalf and on Your sole responsibility, not on behalf
       of any other Contributor, and only if You agree to indemnify,
       defend, and hold each Contributor harmless for any liability
       incurred by, or claims asserted against, such Contributor by reason
       of your accepting any such warranty or additional liability.

    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
    
    1. Definitions.
    
       "License" shall mean the terms and conditions for use, reproduction,
       and distribution as defined by Sections 1 through 9 of this document.
    
       "Licensor" shall mean the copyright owner or entity authorized by
       the copyright owner that is granting the License.
    
       "Legal Entity" shall mean the union of the acting entity and all
       other entities that control, are controlled by, or are under common
       control with that entity. For the purposes of this definition,
       "control" means (i) the power, direct or indirect, to cause the
       direction or management of such entity, whether by contract or
       otherwise, or (ii) ownership of fifty percent (50%) or more of the
       outstanding shares, or (iii) beneficial ownership of such entity.
    
       "You" (or "Your") shall mean an individual or Legal Entity
       exercising permissions granted by this License.
    
       "Source" form shall mean the preferred form for making modifications,
       including but not limited to software source code, documentation
       source, and configuration files.
    
       "Object" form shall mean any form resulting from mechanical
       transformation or translation of a Source form, including but
       not limited to compiled object code, generated documentation,
       and conversions to other media types.
    
       "Work" shall mean the work of authorship, whether in Source or
       Object form, made available under the License, as indicated by a
       copyright notice that is included in or attached to the work
       (an example is provided in the Appendix below).
    
       "Derivative Works" shall mean any work, whether in Source or Object
       form, that is based on (or derived from) the Work and for which the
       editorial revisions, annotations, elaborations, or other modifications
       represent, as a whole, an original work of authorship. For the purposes
       of this License, Derivative Works shall not include works that remain
       separable from, or merely link (or bind by name) to the interfaces of,
       the Work and Derivative Works thereof.
    
       "Contribution" shall mean any work of authorship, including
       the original version of the Work and any modifications or additions
       to that Work or Derivative Works thereof, that is intentionally
       submitted to Licensor for inclusion in the Work by the copyright owner
       or by an individual or Legal Entity authorized to submit on behalf of
       the copyright owner. For the purposes of this definition, "submitted"
       means any form of electronic, verbal, or written communication sent
       to the Licensor or its representatives, including but not limited to
       communication on electronic mailing lists, source code control systems,
       and issue tracking systems that are managed by, or on behalf of, the
       Licensor for the purpose of discussing and improving the Work, but
       excluding communication that is conspicuously marked or otherwise
       designated in writing by the copyright owner as "Not a Contribution."
    
       "Contributor" shall mean Licensor and any individual or Legal Entity
       on behalf of whom a Contribution has been received by Licensor and
       subsequently incorporated within the Work.
    
    2. Grant of Copyright License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       copyright license to reproduce, prepare Derivative Works of,
       publicly display, publicly perform, sublicense, and distribute the
       Work and such Derivative Works in Source or Object form.
    
    3. Grant of Patent License. Subject to the terms and conditions of
       this License, each Contributor hereby grants to You a perpetual,
       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
       (except as stated in this section) patent license to make, have made,
       use, offer to sell, sell, import, and otherwise transfer the Work,
       where such license applies only to those patent claims licensable
       by such Contributor that are necessarily infringed by their
       Contribution(s) alone or by combination of their Contribution(s)
       with the Work to which such Contribution(s) was submitted. If You
       institute patent litigation against any entity (including a
       cross-claim or counterclaim in a lawsuit) alleging that the Work
       or a Contribution incorporated within the Work constitutes direct
       or contributory patent infringement, then any patent licenses
       granted to You under this License for that Work shall terminate
       as of the date such litigation is filed.
    
    4. Redistribution. You may reproduce and distribute copies of the
       Work or Derivative Works thereof in any medium, with or without
       modifications, and in Source or Object form, provided that You
       meet the following conditions:
    
       (a) You must give any other recipients of the Work or
           Derivative Works a copy of this License; and
    
       (b) You must cause any modified files to carry prominent notices
           stating that You changed the files; and
    
       (c) You must retain, in the Source form of any Derivative Works
           that You distribute, all copyright, patent, trademark, and
           attribution notices from the Source form of the Work,
           excluding those notices that do not pertain to any part of
           the Derivative Works; and
    
       (d) If the Work includes a "NOTICE" text file as part of its
           distribution, then any Derivative Works that You distribute must
           include a readable copy of the attribution notices contained
           within such NOTICE file, excluding those notices that do not
           pertain to any part of the Derivative Works, in at least one
           of the following places: within a NOTICE text file distributed
           as part of the Derivative Works; within the Source form or
           documentation, if provided along with the Derivative Works; or,
           within a display generated by the Derivative Works, if and
           wherever such third-party notices normally appear. The contents
           of the NOTICE file are for informational purposes only and
           do not modify the License. You may add Your own attribution
           notices within Derivative Works that You distribute, alongside
           or as an addendum to the NOTICE text from the Work, provided
           that such additional attribution notices cannot be construed
           as modifying the License.
    
       You may add Your own copyright statement to Your modifications and
       may provide additional or different license terms and conditions
       for use, reproduction, or distribution of Your modifications, or
       for any such Derivative Works as a whole, provided Your use,
       reproduction, and distribution of the Work otherwise complies with
       the conditions stated in this License.
    
    5. Submission of Contributions. Unless You explicitly state otherwise,
       any Contribution intentionally submitted for inclusion in the Work
       by You to the Licensor shall be under the terms and conditions of
       this License, without any additional terms or conditions.
       Notwithstanding the above, nothing herein shall supersede or modify
       the terms of any separate license agreement you may have executed
       with Licensor regarding such Contributions.
    
    6. Trademarks. This License does not grant permission to use the trade
       names, trademarks, service marks, or product names of the Licensor,
       except as required for reasonable and customary use in describing the
       origin of the Work and reproducing the content of the NOTICE file.
    
    7. Disclaimer of Warranty. Unless required by applicable law or
       agreed to in writing, Licensor provides the Work (and each
       Contributor provides its Contributions) on an "AS IS" BASIS,
       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
       implied, including, without limitation, any warranties or conditions
       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
       PARTICULAR PURPOSE. You are solely responsible for determining the
       appropriateness of using or redistributing the Work and assume any
       risks associated with Your exercise of permissions under this License.
    
    8. Limitation of Liability. In no event and under no legal theory,
       whether in tort (including negligence), contract, or otherwise,
       unless required by applicable law (such as deliberate and grossly
       negligent acts) or agreed to in writing, shall any Contributor be
       liable to You for damages, including any direct, indirect, special,
       incidental, or consequential damages of any character arising as a
       result of this License or out of the use or inability to use the
       Work (including but not limited to damages for loss of goodwill,
       work stoppage, computer failure or malfunction, or any and all
       other commercial damages or losses), even if such Contributor
       has been advised of the possibility of such damages.
    
    9. Accepting Warranty or Additional Liability. While redistributing
       the Work or Derivative Works thereof, You may choose to offer,
       and charge a fee for, acceptance of support, warranty, indemnity,
       or other liability obligations and/or rights consistent with this
       License. H
