+
+    "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,

+    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 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,

+    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.
