   "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.
