and conversions to other media types.

"Work" shall mean the work of authorship 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, as submitted to the 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, "submit" means any form of electronic, verbal, or

whom a Contribution has been received by the Licensor and included
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

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 the combined work (in 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 any Contribution embodied within
the Work constitutes direct or contributory patent infringement,
then any patent and intellectual property rights granted to You under
this License for that Work shall terminate as of the date such
litigation is filed.

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, You must include a readable copy of the
attribution notices contained within such NOTICE file, in

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 license statement for Your modifications and
may provide additional grant of rights to use, copy, modify, merge,
publish, distribute, sublicense, and/or sell copies of the
Derivative Works, and to permit persons to whom the Derivative
Works are furnished to do so, subject to the following conditions:

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,

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

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 exemplary 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 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 offer only
