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 | ||

|
||
"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. | ||
|

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: | ||
|
||
(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, | ||

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. | ||
