| 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,

| 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.
