"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,

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

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:

   1. You must give any other recipients of the Work or Derivative Works a copy of this License; and

   2. You must cause any modified files to carry prominent notices stating that You changed the files; and

   3. 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

   4. 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.
