+    conversions to other media types.
+
+    "Work" shall mean the work of authorship, whether in Source or Object form, made available under

+    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.
+
+    "Contribution" shall mean any work of authorship, including the original version of the Work and

+
+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,
+    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.
