   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,

   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.
