   "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

   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

   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

   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 the 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 any 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.
