"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

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

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.
