"Object" form shall mean any form resulting from mechanical transformation
or translation of a Source form, including but not limited to compiled object
code, generated documentation, and conversions to other media types.

      

"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

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,

   2. Grant of Copyright License.

Subject to the terms and conditions of this License, each Contributor hereby

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. Any patent license granted
hereby with respect to contributions by an individual employed by an institution
or organization is limited to patent claims where the individual that is the
author of the Work is also the inventor of the patent claims licensed, and
where the organization or institution has the right to grant such license
under applicable grant and research funding agreements. No other express or
implied licenses are granted.

   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. END
