-+ "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

-+ 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,

-+ designated in writing by the copyright 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

-+
-+ 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.
-+
-+ 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 "[]"
-+ replaced with your own identifying information. (Don't include
-+ the brackets!) The text should be enclosed in the appropriate
-+ comment syntax for the file format. We also recommend that a
-+ file or class name and description of purpose be included on the
-+ same "printed page" as the copyright notice for easier
-+ identification within third-party archives.

-+
-+As an exception, if, as a result of your compiling your source code, portions
