"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 that are managed by, or on behalf of, the 
Licensor for the purpose of discussing and improving the Work, but 
excluding communication that is conspicuously marked or otherwise 
designated in writing by the copyright owner 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: 

(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.
