"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

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

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.
