"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

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.
