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

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, 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.
