"Work" shall mean the work of authorship, whether in Source or Object form,

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,

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,

"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.
