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

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.
