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

inclusion in the Work by the copyright owner or by an individual or Legal
48+
Entity authorized to submit on behalf of the copyright owner. For the purposes
49+
of this definition, "submitted" means any form of electronic, verbal, or

in writing by the copyright owner as "Not a Contribution."
56+
57+
"Contributor" shall mean Licensor and any individual or Legal Entity on behalf
58+
of whom a Contribution has been received by Licensor and subsequently
59+

60+
61+
2. Grant of Copyright License. Subject to the terms and conditions of this
62+
License, each Contributor hereby grants to You a perpetual, worldwide,
63+
non-exclusive, no-charge, royalty-free, irrevocable copyright license to
64+
reproduce, prepare Derivative Works of, publicly display, publicly perform,
65+
sublicense, and distribute the Work and such Derivative Works in Source or
66+
Object form.
67+
68+
3. Grant of Patent License. Subject to the terms and conditions of this
69+
License, each Contributor hereby grants to You a perpetual, worldwide,
70+
non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this
71+
section) patent license to make, have made, use, offer to sell, sell, import,
72+
and otherwise transfer the Work, where such license applies only to those
73+
patent claims licensable by such Contributor that are necessarily infringed by
74+
their Contribution(s) alone or by combination of their Contribution(s) with
75+
the Work to which such Contribution(s) was submitted. If You institute patent
76+
litigation against any entity (including a cross-claim or counterclaim in a
77+
lawsuit) alleging that the Work or a Contribution incorporated within the Work
78+
constitutes direct or contributory patent infringement, then any patent
79+
licenses granted to You under this License for that Work shall terminate as of
80+
the date such litigation is filed.
81+
82+
4. Redistribution. You may reproduce and distribute copies of the Work or
83+
Derivative Works thereof in any medium, with or without modifications, and in
84+
Source or Object form, provided that You meet the following conditions:
85+
86+
You must give any other recipients of the Work or Derivative Works a copy of
87+
this License; and
88+
89+
You must cause any modified files to carry prominent notices stating that You
90+
changed the files; and
91+
92+
You must retain, in the Source form of any Derivative Works that You
93+
distribute, all copyright, patent, trademark, and attribution notices from the
94+
Source form of the Work, excluding those notices that do not pertain to any
95+
part of the Derivative Works; and
96+
97+
If the Work includes a "NOTICE" text file as part of its distribution, then
98+
any Derivative Works that You distribute must include a readable copy of the
99+
attribution notices contained within such NOTICE file, excluding those notices
100+
that do not pertain to any part of the Derivative Works, in at least one of
101+
the following places: within a NOTICE text file distributed as part of the
102+
Derivative Works; within the Source form or documentation, if provided along
103+
with the Derivative Works; or, within a display generated by the Derivative
104+
Works, if and wherever such third-party notices normally appear. The contents
105+
of the NOTICE file are for informational purposes only and do not modify the
106+
License. You may add Your own attribution notices within Derivative Works that
107+
You distribute, alongside or as an addendum to the NOTICE text from the Work,
108+
provided that such additional attribution notices cannot be construed as
109+
modifying the License. You may add Your own copyright statement to Your
110+
modifications and may provide additional or different license terms and
111+
conditions for use, reproduction, or distribution of Your modifications, or
112+
for any such Derivative Works as a whole, provided Your use, reproduction, and
113+
distribution of the Work otherwise complies with the conditions stated in this
114+
License. 5. Submission of Contributions. Unless You explicitly state
115+
otherwise, any Contribution intentionally submitted for inclusion in the Work
116+
by You to the Licensor shall be under the terms and conditions of this
117+
License, without any additional terms or conditions. Notwithstanding the
118+
above, nothing herein shall supersede or modify the terms of any separate
119+
license agreement you may have executed with Licensor regarding such
120+
Contributions.
121+
122+
6. Trademarks. This License does not grant permission to use the trade names,
123+
trademarks, service marks, or product names of the Licensor, except as
124+
required for reasonable and customary use in describing the origin of the Work
125+
and reproducing the content of the NOTICE file.
126+
127+
7. Disclaimer of Warranty. Unless required by applicable law or agreed to in
128+
writing, Licensor provides the Work (and each Contributor provides its
129+
Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
130+
KIND, either express or implied, including, without limitation, any warranties
131+
or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
132+
PARTICULAR PURPOSE. You are solely responsible for determining the
133+
appropriateness of using or redistributing the Work and assume any risks
134+
associated with Your exercise of permissions under this License.
135+
136+
8. Limitation of Liability. In no event and under no legal theory, whether in
137+
tort (including negligence), contract, or otherwise, unless required by
138+
applicable law (such as deliberate and grossly negligent acts) or agreed to in
139+
writing, shall any Contributor be liable to You for damages, including any
140+
direct, indirect, special, incidental, or consequential damages of any
141+
character arising as a result of this License or out of the use or inability
142+
to use the Work (including but not limited to damages for loss of goodwill,
143+
work stoppage, computer failure or malfunction, or any and all other
144+
commercial damages or losses), even if such Contributor has been advised of
145+
the possibility of such damages.
146+
147+
9. Accepting Warranty or Additional Liability. While redistributing the Work
148+
or Derivative Works thereof, You may choose to offer, and charge a fee for,
149+
acceptance of support, warranty, indemnity, or other liability obligations
150+
and/or rights consistent with this License. However, in accepting such
151+
obligations, You may act only on Your own behalf and on Your sole
152+
responsibility, not on behalf of any other Contributor, and only if You agree
153+
to indemnify, defend, and hold each Contributor harmless for any liability
154+
incurred by, or claims asserted against, such Contributor by reason of your
155+
accepting any such warranty or additional liability.
