75
+ Object form, made available under the License, as indicated by a
76
+ copyright notice that is included in or attached to the work
77
+ (an example is provided in the Appendix below).
78
+
79
+ "Derivative Works" shall mean any work, whether in Source or Object
80
+ form, that is based on (or derived from) the Work and for which the
81
+ editorial revisions, annotations, elaborations, or other modifications
82
+ represent, as a whole, an original work of authorship. For the purposes
83
+ of this License, Derivative Works shall not include works that remain
84
+ separable from, or merely link (or bind by name) to the interfaces of,
85
+ the Work and Derivative Works thereof.
86
+
87
+ "Contribution" shall mean any work of authorship, including
88
+ the original version of the Work and any modifications or additions
89
+ to that Work or Derivative Works thereof, that is intentionally
90
+ submitted to Licensor for inclusion in the Work by the copyright owner
91
+ or by an individual or Legal Entity authorized to submit on behalf of
92
+ the copyright owner. For the purposes of this definition, "submitted"
93
+ means any form of electronic, verbal, or written communication sent
94
+ to the Licensor or its representatives, including but not limited to
95
+ communication on electronic mailing lists, source code control systems,
96
+ and issue tracking systems that are managed by, or on behalf of, the

+
101
+ "Contributor" shall mean Licensor and any individual or Legal Entity

+ subsequently incorporated within the Work.
104
+
105
+ 2. Grant of Copyright License. Subject to the terms and conditions of
106
+ this License, each Contributor hereby grants to You a perpetual,
107
+ worldwide, non-exclusive, no-charge, royalty-free, irrevocable
108
+ copyright license to reproduce, prepare Derivative Works of,
109
+ publicly display, publicly perform, sublicense, and distribute the
110
+ Work and such Derivative Works in Source or Object form.
111
+
112
+ 3. Grant of Patent License. Subject to the terms and conditions of

115
+ (except as stated in this section) patent license to make, have made,
116
+ use, offer to sell, sell, import, and otherwise transfer the Work,

+ where such license applies only to those patent claims licensable
118
+ by such Contributor that are necessarily infringed by their
119
+ Contribution(s) alone or by combination of their Contribution(s)
120
+ with the Work to which such Contribution(s) was submitted. If You
121
+ institute patent litigation against any entity (including a
122
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
123
+ or a Contribution incorporated within the Work constitutes direct
124
+ or contributory patent infringement, then any patent licenses
125
+ granted to You under this License for that Work shall terminate
126
+ as of the date such litigation is filed.
127
+
128
+ 4. Redistribution. You may reproduce and distribute copies of the
129
+ Work or Derivative Works thereof in any medium, with or without
130
+ modifications, and in Source or Object form, provided that You
131
+ meet the following conditions:
132
+
133
+ (a) You must give any other recipients of the Work or
134
+ Derivative Works a copy of this License; and
135
+
136
+ (b) You must cause any modified files to carry prominent notices
137
+ stating that You changed the files; and
138
+
139
+ (c) You must retain, in the Source form of any Derivative Works
140
+ that You distribute, all copyright, patent, trademark, and
141
+ attribution notices from the Source form of the Work,
142
+ excluding those notices that do not pertain to any part of
143
+ the Derivative Works; and
144
+
145
+ (d) If the Work includes a "NOTICE" text file as part of its
146
+ distribution, then any Derivative Works that You distribute must
147
+ include a readable copy of the attribution notices contained
148
+ within such NOTICE file, excluding those notices that do not
149
+ pertain to any part of the Derivative Works, in at least one
150
+ of the following places: within a NOTICE text file distributed
151
+ as part of the Derivative Works; within the Source form or
152
+ documentation, if provided along with the Derivative Works; or,
153
+ within a display generated by the Derivative Works, if and
154
+ wherever such third-party notices normally appear. The contents
155
+ of the NOTICE file are for informational purposes only and
156
+ do not modify the License. You may add Your own attribution
157
+ notices within Derivative Works that You distribute, alongside
158
+ or as an addendum to the NOTICE text from the Work, provided
159
+ that such additional attribution notices cannot be construed
160
+ as modifying the License.
161
+
162
+ You may add Your own copyright statement to Your modifications and
163
+ may provide additional or different license terms and conditions
164
+ for use, reproduction, or distribution of Your modifications, or
165
+ for any such Derivative Works as a whole, provided Your use,
166
+ reproduction, and distribution of the Work otherwise complies with
167
+ the conditions stated in this License.
168
+
169
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
170
+ any Contribution intentionally submitted for inclusion in the Work
171
+ by You to the Licensor shall be under the terms and conditions of
172
+ this License, without any additional terms or conditions.
173
+ Notwithstanding the above, nothing herein shall supersede or modify
174
+ the terms of any separate license agreement you may have executed
175
+ with Licensor regarding such Contributions.
176
+
177
+ 6. Trademarks. This License does not grant permission to use the trade
178
+ names, trademarks, service marks, or product names of the Licensor,
179
+ except as required for reasonable and customary use in describing the
180
+ origin of the Work and reproducing the content of the NOTICE file.
181
+
182
+ 7. Disclaimer of Warranty. Unless required by applicable law or
183
+ agreed to in writing, Licensor provides the Work (and each
184
+ Contributor provides its Contributions) on an "AS IS" BASIS,
185
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
186
+ implied, including, without limitation, any warranties or conditions
187
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
188
+ PARTICULAR PURPOSE. You are solely responsible for determining the
189
+ appropriateness of using or redistributing the Work and assume any
190
+ risks associated with Your exercise of permissions under this License.
191
+
192
+ 8. Limitation of Liability. In no event and under no legal theory,
193
+ whether in tort (including negligence), contract, or otherwise,
194
+ unless required by applicable law (such as deliberate and grossly
195
+ negligent acts) or agreed to in writing, shall any Contributor be
196
+ liable to You for damages, including any direct, indirect, special,
197
+ incidental, or consequential damages of any character arising as a
198
+ result of this License or out of the use or inability to use the
199
+ Work (including but not limited to damages for loss of goodwill,
200
+ work stoppage, computer failure or malfunction, or any and all
201
+ other commercial damages or losses), even if such Contributor
202
+ has been advised of the possibility of such damages.
203
+
204
+ 9. Accepting Warranty or Additional Liability. While redistributing
205
+ the Work or Derivative Works thereof, You may choose to offer,
206
+ and charge a fee for, acceptance of support, warranty, indemnity,
207
+ or other liability obligations and/or rights consistent with this
208
+ License. However, in accepting such obligations, You may act only
209
+ on Your own behalf and on Your sole responsibility, not on behalf
210
+ of any other Contributor, and only if You agree to indemnify,
211
+ defend, and hold each Contributor harmless for any liability
212
+ incurred by, or claims asserted against, such Contributor by reason
213
+ of your accepting any such warranty or additional liability.
