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

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

"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

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.
