+\r
+      "Derivative Works" shall mean any work, whether in Source or Object\r
+      form, that is based on (or derived from) the Work and for which the\r
+      editorial revisions, annotations, elaborations, or other modifications\r
+      represent, as a whole, an original work of authorship. For the purposes\r
+      of this License, Derivative Works shall not include works that remain\r
+      separable from, or merely link (or bind by name) to the interfaces of,\r
+      the Work and Derivative Works thereof.\r
+\r

+      copyright license to reproduce, prepare Derivative Works of,\r

+      by such Contributor that are necessarily infringed by their\r
+      Contribution(s) alone or by combination of their Contribution(s)\r
+      with the Work to which such Contribution(s) was submitted. If You\r
+      institute patent litigation against any entity (including a\r
+      cross-claim or counterclaim in a lawsuit) alleging that the Work\r
+      or a Contribution incorporated within the Work constitutes direct\r
+      or contributory patent infringement, then any patent licenses\r
+      granted to You under this License for that Work shall terminate\r
+      as of the date such litigation is filed.\r
+\r
+   4. Redistribution. You may reproduce and distribute copies of the\r
+      Work or Derivative Works thereof in any medium, with or without\r
+      modifications, and in Source or Object form, provided that You\r
+      meet the following conditions:\r
+\r
+      (a) You must give any other recipients of the Work or\r
+          Derivative Works a copy of this License; and\r
+\r
+      (b) You must cause any modified files to carry prominent notices\r
+          stating that You changed the files; and\r
+\r
+      (c) You must retain, in the Source form of any Derivative Works\r
+          that You distribute, all copyright, patent, trademark, and\r
+          attribution notices from the Source form of the Work,\r
+          excluding those notices that do not pertain to any part of\r
+          the Derivative Works; and\r
+\r
+      (d) If the Work includes a "NOTICE" text file as part of its\r
+          distribution, then any Derivative Works that You distribute must\r
+          include a readable copy of the attribution notices contained\r
+          within such NOTICE file, excluding those notices that do not\r
+          pertain to any part of the Derivative Works, in at least one\r
+          of the following places: within a NOTICE text file distributed\r
+          as part of the Derivative Works; within the Source form or\r
+          documentation, if provided along with the Derivative Works; or,\r
+          within a display generated by the Derivative Works, if and\r
+          wherever such third-party notices normally appear. The contents\r
+          of the NOTICE file are for informational purposes only and\r
+          do not modify the License. You may add Your own attribution\r
+          notices within Derivative Works that You distribute, alongside\r
+          or as an addendum to the NOTICE text from the Work, provided\r
+          that such additional attribution notices cannot be construed\r
+          as modifying the License.\r
+\r
+      You may add Your own copyright statement to Your modifications and\r
+      may provide additional or different license terms and conditions\r
+      for use, reproduction, or distribution of Your modifications, or\r
+      for any such Derivative Works as a whole, provided Your use,\r
+      reproduction, and distribution of the Work otherwise complies with\r
+      the conditions stated in this License.\r
+\r
+   5. Submission of Contributions. Unless You explicitly state otherwise,\r
+      any Contribution intentionally submitted for inclusion in the Work\r
+      by You to the Licensor shall be under the terms and conditions of\r
+      this License, without any additional terms or conditions.\r
+      Notwithstanding the above, nothing herein shall supersede or modify\r
+      the terms of any separate license agreement you may have executed\r
+      with Licensor regarding such Contributions.\r
+\r
+   6. Trademarks. This License does not grant permission to use the trade\r
+      names, trademarks, service marks, or product names of the Licensor,\r
+      except as required for reasonable and customary use in describing the\r
+      origin of the Work and reproducing the content of the NOTICE file.\r
+\r
+   7. Disclaimer of Warranty. Unless required by applicable law or\r
+      agreed to in writing, Licensor provides the Work (and each\r
+      Contributor provides its Contributions) on an "AS IS" BASIS,\r
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or\r
+      implied, including, without limitation, any warranties or conditions\r
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A\r
+      PARTICULAR PURPOSE. You are solely responsible for determining the\r
+      appropriateness of using or redistributing the Work and assume any\r
+      risks associated with Your exercise of permissions under this License.\r
+\r
+   8. Limitation of Liability. In no event and under no legal theory,\r
+      whether in tort (including negligence), contract, or otherwise,\r
+      unless required by applicable law (such as deliberate and grossly\r
+      negligent acts) or agreed to in writing, shall any Contributor be\r
+      liable to You for damages, including any direct, indirect, special,\r
+      incidental, or consequential damages of any character arising as a\r
+      result of this License or out of the use or inability to use the\r
+      Work (including but not limited to damages for loss of goodwill,\r
+      work stoppage, computer failure or malfunction, or any and all\r
+      other commercial damages or losses), even if such Contributor\r
+      has been advised of the possibility of such damages.\r
+\r
+   9. Accepting Warranty or Additional Liability. While redistributing\r
+      the Work or Derivative Works thereof, You may choose to offer,\r
+      and charge a fee for, acceptance of support, warranty, indemnity,\r
+      or other liability obligations and/or rights consistent with this\r
+      License. However, in accepting such obligations, You may act only\r
+      on Your own behalf and on Your sole responsibility, not on behalf\r
+      of any other Contributor, and only if You agree to indemnify,\r
+      defend, and hold each Contributor harmless for any liability\r
+      incurred by, or claims asserted against, such Contributor by reason\r
+      of your accepting any such warranty or additional liability.\r
+\r
+   END OF TERMS AND CONDITIONS\r

+   APPENDIX: How to apply the Apache License to your work.\r
