|
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,

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

|
provided that You meet the following conditions:
|
|
You must give any other recipients of the Work or Derivative Works a copy of
|
this License; and

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

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
|
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

|
Unless You explicitly state otherwise, any Contribution intentionally submitted

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.
