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

"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, 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:

You must give any other recipients of the Work or Derivative Works a copy of this License; 
and

You must cause any modified files to carry prominent notices stating that You changed the 
files; and

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

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.
