31+
transformation or translation of a Source form, including but
32+
not limited to compiled object code, generated documentation,

and conversions to other media types.
34+
35+
"Work" shall mean the work of authorship, whether in Source or
36+
Object form, made available under the License, as indicated by a
37+
copyright notice that is included in or attached to the work.
38+
39+
"Derivative Works" shall mean any work, whether in Source or Object
40+
form, that is based on (or derived from) the Work and for which the
41+
editorial revisions, annotations, elaborations, or other modifications
42+
represent, as a whole, an original work of authorship. For the purposes
43+
of this License, Derivative Works shall not include works that remain
44+
separable from, or merely link (or bind by name) to the interfaces of,
45+
the Work and Derivative Works thereof.
46+
47+
"Contribution" shall mean any work of authorship, including
48+
the original version of the Work and any modifications or additions
49+
to that Work or Derivative Works thereof, that is intentionally

66+
this License, each Contributor hereby grants to You a perpetual,
67+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
68+

78+
by such Contributor that are necessarily infringed by their
79+
Contribution(s) alone or by combination of their Contribution(s)
80+
with the Work to which such Contribution(s) was submitted. If You
81+
institute patent litigation against any entity (including a
82+
cross-claim or counterclaim in a lawsuit) alleging that the Work
83+
or a Contribution incorporated within the Work constitutes direct
84+
or contributory patent infringement, then any patent licenses
85+
granted to You under this License for that Work shall terminate
86+
as of the date such litigation is filed.
87+
88+
4. Redistribution. You may reproduce and distribute copies of the
89+
Work or Derivative Works thereof in any medium, with or without
90+
modifications, and in Source or Object form, provided that You
91+
meet the following conditions:
92+
93+
(a) You must give any other recipients of the Work or
94+
Derivative Works a copy of this License; and
95+
96+
(b) You must cause any modified files to carry prominent notices
97+
stating that You changed the files; and
98+
99+
(c) You must retain, in the Source form of any Derivative Works
100+
that You distribute, all copyright, patent, trademark, and
101+
attribution notices from the Source form of the Work,
102+
excluding those notices that do not pertain to any part of
103+
the Derivative Works; and
104+
105+
(d) If the Work includes a "NOTICE" text file as part of its
106+
distribution, then any Derivative Works that You distribute must
107+
include a readable copy of the attribution notices contained
108+
within such NOTICE file, excluding those notices that do not
109+
pertain to any part of the Derivative Works, in at least one
110+
of the following places: within a NOTICE text file distributed
111+
as part of the Derivative Works; within the Source form or
112+
documentation, if provided along with the Derivative Works; or,
113+
within a display generated by the Derivative Works, if and
114+
wherever such third-party notices normally appear. The contents
115+
of the NOTICE file are for informational purposes only and
116+
do not modify the License. You may add Your own attribution
117+
notices within Derivative Works that You distribute, alongside
118+
or as an addendum to the NOTICE text from the Work, provided
119+
that such additional attribution notices cannot be construed
120+
as modifying the License.
121+
122+
You may add Your own copyright statement to Your modifications and
123+
may provide additional or different license terms and conditions
124+
for use, reproduction, or distribution of Your modifications, or
125+
for any such Derivative Works as a whole, provided Your use,
126+
reproduction, and distribution of the Work otherwise complies with
127+
the conditions stated in this License.
128+
129+
5. Submission of Contributions. Unless You explicitly state otherwise,
130+
any Contribution intentionally submitted for inclusion in the Work
131+
by You to the Licensor shall be under the terms and conditions of
132+
this License, without any additional terms or conditions.
133+
Notwithstanding the above, nothing herein shall supersede or modify
134+
the terms of any separate license agreement you may have executed
135+
with Licensor regarding such Contributions.
136+
137+
6. Trademarks. This License does not grant permission to use the trade
138+
names, trademarks, service marks, or product names of the Licensor,
139+
except as required for reasonable and customary use in describing the
140+
origin of the Work and reproducing the content of the NOTICE file.
141+
142+
7. Disclaimer of Warranty. Unless required by applicable law or
143+
agreed to in writing, Licensor provides the Work (and each
144+
Contributor provides its Contributions) on an "AS IS" BASIS,
145+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
146+
implied, including, without limitation, any warranties or conditions
147+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
148+
PARTICULAR PURPOSE. You are solely responsible for determining the
149+
appropriateness of using or redistributing the Work and assume any
150+
risks associated with Your exercise of permissions under this License.
151+
152+
8. Limitation of Liability. In no event and under no legal theory,
153+
whether in tort (including negligence), contract, or otherwise,
154+
unless required by applicable law (such as deliberate and grossly
155+
negligent acts) or agreed to in writing, shall any Contributor be
156+
liable to You for damages, including any direct, indirect, special,
157+
incidental, or consequential damages of any character arising as a
158+
result of this License or out of the use or inability to use the
159+
Work (including but not limited to damages for loss of goodwill,
160+
work stoppage, computer failure or malfunction, or any and all
161+
other commercial damages or losses), even if such Contributor
162+
has been advised of the possibility of such damages.
163+
164+
9. Accepting Warranty or Additional Liability. While redistributing
165+
the Work or Derivative Works thereof, You may choose to offer,
166+
and charge a fee for, acceptance of support, warranty, indemnity,
167+
or other liability obligations and/or rights consistent with this
168+
License. However, in accepting such obligations, You may act only
169+
on Your own behalf and on Your sole responsibility, not on behalf
170+
of any other Contributor, and only if You agree to indemnify,
171+
defend, and hold each Contributor harmless for any liability
172+
incurred by, or claims asserted against, such Contributor by reason
173+
of your accepting any such warranty or additional liability.
