-       source, and configuration files.
-
-       "Object" form shall mean any form resulting from mechanical
-       transformation or translation of a Source form, including but
-       not limited to compiled object code, generated documentation,
-       and conversions to other media types.
-
-       "Work" shall mean the work of authorship, whether in Source or
-       Object form, made available under the License, as indicated by a
-       copyright notice that is included in or attached to the work
-       (an example is provided in the Appendix below).
-
-       "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.
-
-       "Contribution" shall mean any work of authorship, including
-       the original version of the Work and any modifications or additions
-       to that Work or Derivative Works thereof, that is intentionally
-       submitted to Licensor for inclusion in the Work by the copyright owner
-       or by an individual or Legal Entity authorized to submit on behalf of
-       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,
-       and issue tracking systems that are managed by, or on behalf of, the
-       Licensor for the purpose of discussing and improving the Work, but

-
-       "Contributor" shall mean Licensor and any individual or Legal Entity
-       on behalf of whom a Contribution has been received by Licensor 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,

-       (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

+   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

+   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+   copyright license to reproduce, prepare Derivative Works of,

+   Work and such Derivative Works in Source or Object form.
+

+   by such Contributor that are necessarily infringed by their

+       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

+       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

+       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

+
+   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

+   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,

+   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
