other entities that control, are controlled by, or are under common
23+
control with that entity. For the purposes of this definition,

25+
direction or management of such entity, whether by contract or
26+
otherwise, or (ii) ownership of fifty percent (50%) or more of the

29+
"You" (or "Your") shall mean an individual or Legal Entity
30+
exercising permissions granted by this License.
31+
32+
"Source" form shall mean the preferred form for making modifications,
33+
including but not limited to software source code, documentation
34+
source, and configuration files.
35+
36+
"Object" form shall mean any form resulting from mechanical
37+
transformation or translation of a Source form, including but
38+
not limited to compiled object code, generated documentation,
39+
and conversions to other media types.
40+
41+
"Work" shall mean the work of authorship, whether in Source or
42+
Object form, made available under the License, as indicated by a
43+
copyright notice that is included in or attached to the work
44+
(an example is provided in the Appendix below).
45+
46+
"Derivative Works" shall mean any work, whether in Source or Object
47+
form, that is based on (or derived from) the Work and for which the
48+
editorial revisions, annotations, elaborations, or other modifications
49+
represent, as a whole, an original work of authorship. For the purposes
50+
of this License, Derivative Works shall not include works that remain
51+
separable from, or merely link (or bind by name) to the interfaces of,
52+
the Work and Derivative Works thereof.
53+
54+
"Contribution" shall mean any work of authorship, including
55+
the original version of the Work and any modifications or additions
56+
to that Work or Derivative Works thereof, that is intentionally
57+
submitted to Licensor for inclusion in the Work by the copyright owner
58+
or by an individual or Legal Entity authorized to submit on behalf of
59+
the copyright owner. For the purposes of this definition, "submitted"
60+
means any form of electronic, verbal, or written communication sent
61+
to the Licensor or its representatives, including but not limited to
62+
communication on electronic mailing lists, source code control systems,
63+
and issue tracking systems that are managed by, or on behalf of, the
64+
Licensor for the purpose of discussing and improving the Work, but
65+
excluding communication that is conspicuously marked or otherwise
66+
designated in writing by the copyright owner as "Not a Contribution."
67+
68+
"Contributor" shall mean Licensor and any individual or Legal Entity
69+
on behalf of whom a Contribution has been received by Licensor and
70+
subsequently incorporated within the Work.
71+
72+
2. Grant of Copyright License. Subject to the terms and conditions of
73+
this License, each Contributor hereby grants to You a perpetual,
74+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
75+
copyright license to reproduce, prepare Derivative Works of,
76+
publicly display, publicly perform, sublicense, and distribute the
77+
Work and such Derivative Works in Source or Object form.
78+
79+
3. Grant of Patent License. Subject to the terms and conditions of
80+
this License, each Contributor hereby grants to You a perpetual,
81+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
82+
(except as stated in this section) patent license to make, have made,
83+
use, offer to sell, sell, import, and otherwise transfer the Work,
84+
where such license applies only to those patent claims licensable
85+
by such Contributor that are necessarily infringed by their
86+
Contribution(s) alone or by combination of their Contribution(s)
87+
with the Work to which such Contribution(s) was submitted. If You
88+
institute patent litigation against any entity (including a
89+
cross-claim or counterclaim in a lawsuit) alleging that the Work
90+
or a Contribution incorporated within the Work constitutes direct
91+
or contributory patent infringement, then any patent licenses
92+
granted to You under this License for that Work shall terminate
93+
as of the date such litigation is filed.
94+
95+
4. Redistribution. You may reproduce and distribute copies of the
96+
Work or Derivative Works thereof in any medium, with or without
97+
modifications, and in Source or Object form, provided that You
98+
meet the following conditions:
99+
100+
(a) You must give any other recipients of the Work or
101+
Derivative Works a copy of this License; and
102+
103+
(b) You must cause any modified files to carry prominent notices
104+
stating that You changed the files; and
105+
106+
(c) You must retain, in the Source form of any Derivative Works
107+
that You distribute, all copyright, patent, trademark, and
108+
attribution notices from the Source form of the Work,
109+
excluding those notices that do not pertain to any part of
110+
the Derivative Works; and
111+
112+
(d) If the Work includes a "NOTICE" text file as part of its
113+
distribution, then any Derivative Works that You distribute must
114+
include a readable copy of the attribution notices contained
115+
within such NOTICE file, excluding those notices that do not
116+
pertain to any part of the Derivative Works, in at least one
117+
of the following places: within a NOTICE text file distributed
118+
as part of the Derivative Works; within the Source form or
119+
documentation, if provided along with the Derivative Works; or,
120+
within a display generated by the Derivative Works, if and
121+
wherever such third-party notices normally appear. The contents
122+
of the NOTICE file are for informational purposes only and
123+
do not modify the License. You may add Your own attribution
124+
notices within Derivative Works that You distribute, alongside
125+
or as an addendum to the NOTICE text from the Work, provided
126+
that such additional attribution notices cannot be construed
127+
as modifying the License.
128+
129+
You may add Your own copyright statement to Your modifications and
130+
may provide additional or different license terms and conditions
131+
for use, reproduction, or distribution of Your modifications, or
132+
for any such Derivative Works as a whole, provided Your use,
133+
reproduction, and distribution of the Work otherwise complies with
134+
the conditions stated in this License.
135+
136+
5. Submission of Contributions. Unless You explicitly state otherwise,
137+
any Contribution intentionally submitted for inclusion in the Work
138+
by You to the Licensor shall be under the terms and conditions of
139+
this License, without any additional terms or conditions.
140+
Notwithstanding the above, nothing herein shall supersede or modify
141+
the terms of any separate license agreement you may have executed
142+
with Licensor regarding such Contributions.
143+
144+
6. Trademarks. This License does not grant permission to use the trade
145+
names, trademarks, service marks, or product names of the Licensor,
146+
except as required for reasonable and customary use in describing the
147+
origin of the Work and reproducing the content of the NOTICE file.
148+
149+
7. Disclaimer of Warranty. Unless required by applicable law or
150+
agreed to in writing, Licensor provides the Work (and each
151+
Contributor provides its Contributions) on an "AS IS" BASIS,
152+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
153+
implied, including, without limitation, any warranties or conditions
154+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
155+
PARTICULAR PURPOSE. You are solely responsible for determining the
156+
appropriateness of using or redistributing the Work and assume any
157+
risks associated with Your exercise of permissions under this License.
158+
159+
8. Limitation of Liability. In no event and under no legal theory,
160+
whether in tort (including negligence), contract, or otherwise,
161+
unless required by applicable law (such as deliberate and grossly
162+
negligent acts) or agreed to in writing, shall any Contributor be
163+
liable to You for damages, including any direct, indirect, special,
164+
incidental, or consequential damages of any character arising as a
165+
result of this License or out of the use or inability to use the
166+
Work (including but not limited to damages for loss of goodwill,
167+
work stoppage, computer failure or malfunction, or any and all
168+
other commercial damages or losses), even if such Contributor
169+
has been advised of the possibility of such damages.
170+
171+
9. Accepting Warranty or Additional Liability. While redistributing
172+
the Work or Derivative Works thereof, You may choose to offer,
173+
and charge a fee for, acceptance of support, warranty, indemnity,
174+
or other liability obligations and/or rights consistent with this
175+
License. However, in accepting such obligations, You may act only
176+
on Your own behalf and on Your sole responsibility, not on behalf
177+
of any other Contributor, and only if You agree to indemnify,
178+
defend, and hold each Contributor harmless for any liability
179+
incurred by, or claims asserted against, such Contributor by reason
180+
of your accepting any such warranty or additional liability.
181+
182+
END OF TERMS AND CONDITIONS
