- *      with the Work to which such Contribution(s) was submitted. If You

- *      (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.
- *
- *   END OF TERMS AND CONDITIONS
- *
- *   APPENDIX: How to apply the Apache License to your work.
- *
- *      To apply the Apache License to your work, attach the following
- *      boilerplate notice, with the fields enclosed by brackets "[]"

- *          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

- *
- *      You may add Your own copyright statement to Your modifications and

- *
- *   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

- *      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

- *      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

- *      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.

- *      "Work" shall mean the work of authorship, whether in Source or
- *      Object form, made available under the License, as indicated by a

- *
- *      "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.

- *      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.
