1. Grant of Copyright License. Subject to the terms and conditions of this
License, each Contributor hereby grants to You a perpetual, worldwide,

reproduce, prepare Derivative Works of, publicly display, publicly perform,
sublicense, and distribute the Work and such Derivative Works in Source or
Object form.

2. 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.

3. 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.

1. 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.

2. 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.

3. 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.

4. 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.

5. 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 such
cases, You may choose to offer such rights only on Your own behalf and
You must take care to not impose any further restrictions on the
recipients' exercise of the rights granted under this License. You must
also make sure Your distribution of the Work otherwise complies with the
conditions stated in this License.

6. Miscellaneous. This License represents the complete agreement
concerning the subject matter hereof. If any provision of this License is
held to be unenforceable, such provision shall be reformed only to the
extent necessary to make it enforceable. The headings in this License are
for convenience only and do not affect the interpretation of this License.

7. Version; later versions. Licensor may publish revised and/or new
versions of the License from time to time. Such new versions will be
similar in spirit to the present version, but may differ in detail to
address new problems or concerns. Each version is given a distinguishing
version number. If the Work specifies a version of this License which
applies to it and "any later version", You may choose to follow the terms
and conditions either of that specified version or of any later version
published by the Licensor. If the Work does not specify a version number,
You may choose any version ever published by the Licensor.
