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

behalf of whom a Contribution has been received by Licensor and subsequently

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.
