90
91      "Derivative Works" shall mean any work, whether in Source or Object
92      form, that is based on (or derived from) the Work and for which the
93      editorial revisions, annotations, elaborations, or other modifications
94      represent, as a whole, an original work of authorship. For the purposes
95      of this License, Derivative Works shall not include works that remain
96      separable from, or merely link (or bind by name) to the interfaces of,
97      the Work and Derivative Works thereof.
98
99      "Contribution" shall mean any work of authorship, including
100      the original version of the Work and any modifications or additions
101      to that Work or Derivative Works thereof, that is intentionally
102      submitted to Licensor for inclusion in the Work by the copyright owner
103      or by an individual or Legal Entity authorized to submit on behalf of
104      the copyright owner. For the purposes of this definition, "submitted"
105      means any form of electronic, verbal, or written communication sent
106      to the Licensor or its representatives, including but not limited to

112
113      "Contributor" shall mean Licensor and any individual or Legal Entity
114      on behalf of whom a Contribution has been received by Licensor and
115      subsequently incorporated within the Work.

117   2. Grant of Copyright License. Subject to the terms and conditions of
118      this License, each Contributor hereby grants to You a perpetual,
119      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
120      copyright license to reproduce, prepare Derivative Works of,
121      publicly display, publicly perform, sublicense, and distribute the
122      Work and such Derivative Works in Source or Object form.
123
124   3. Grant of Patent License. Subject to the terms and conditions of
125      this License, each Contributor hereby grants to You a perpetual,
126      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
127      (except as stated in this section) patent license to make, have made,
128      use, offer to sell, sell, import, and otherwise transfer the Work,
129      where such license applies only to those patent claims licensable
130      by such Contributor that are necessarily infringed by their
131      Contribution(s) alone or by combination of their Contribution(s)
132      with the Work to which such Contribution(s) was submitted. If You
133      institute patent litigation against any entity (including a
134      cross-claim or counterclaim in a lawsuit) alleging that the Work
135      or a Contribution incorporated within the Work constitutes direct
136      or contributory patent infringement, then any patent licenses
137      granted to You under this License for that Work shall terminate
138      as of the date such litigation is filed.
139
140   4. Redistribution. You may reproduce and distribute copies of the
141      Work or Derivative Works thereof in any medium, with or without
142      modifications, and in Source or Object form, provided that You
143      meet the following conditions:
144
145      (a) You must give any other recipients of the Work or
146          Derivative Works a copy of this License; and
147
148      (b) You must cause any modified files to carry prominent notices
149          stating that You changed the files; and
150
151      (c) You must retain, in the Source form of any Derivative Works
152          that You distribute, all copyright, patent, trademark, and
153          attribution notices from the Source form of the Work,
154          excluding those notices that do not pertain to any part of
155          the Derivative Works; and
156
157      (d) If the Work includes a "NOTICE" text file as part of its
158          distribution, then any Derivative Works that You distribute must
159          include a readable copy of the attribution notices contained
160          within such NOTICE file, excluding those notices that do not
161          pertain to any part of the Derivative Works, in at least one
162          of the following places: within a NOTICE text file distributed
163          as part of the Derivative Works; within the Source form or
164          documentation, if provided along with the Derivative Works; or,
165          within a display generated by the Derivative Works, if and
166          wherever such third-party notices normally appear. The contents
167          of the NOTICE file are for informational purposes only and
168          do not modify the License. You may add Your own attribution
169          notices within Derivative Works that You distribute, alongside
170          or as an addendum to the NOTICE text from the Work, provided
171          that such additional attribution notices cannot be construed
172          as modifying the License.
173
174      You may add Your own copyright statement to Your modifications and
175      may provide additional or different license terms and conditions
176      for use, reproduction, or distribution of Your modifications, or
177      for any such Derivative Works as a whole, provided Your use,
178      reproduction, and distribution of the Work otherwise complies with
179      the conditions stated in this License.
180
181   5. Submission of Contributions. Unless You explicitly state otherwise,
182      any Contribution intentionally submitted for inclusion in the Work
183      by You to the Licensor shall be under the terms and conditions of
184      this License, without any additional terms or conditions.
185      Notwithstanding the above, nothing herein shall supersede or modify
186      the terms of any separate license agreement you may have executed
187      with Licensor regarding such Contributions.
188
189   6. Trademarks. This License does not grant permission to use the trade
190      names, trademarks, service marks, or product names of the Licensor,
191      except as required for reasonable and customary use in describing the
192      origin of the Work and reproducing the content of the NOTICE file.
193
194   7. Disclaimer of Warranty. Unless required by applicable law or
195      agreed to in writing, Licensor provides the Work (and each
196      Contributor provides its Contributions) on an "AS IS" BASIS,
197      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
198      implied, including, without limitation, any warranties or conditions
199      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
200      PARTICULAR PURPOSE. You are solely responsible for determining the
201      appropriateness of using or redistributing the Work and assume any
202      risks associated with Your exercise of permissions under this License.
203
204   8. Limitation of Liability. In no event and under no legal theory,
205      whether in tort (including negligence), contract, or otherwise,
206      unless required by applicable law (such as deliberate and grossly
207      negligent acts) or agreed to in writing, shall any Contributor be
208      liable to You for damages, including any direct, indirect, special,
209      incidental, or consequential damages of any character arising as a
210      result of this License or out of the use or inability to use the
211      Work (including but not limited to damages for loss of goodwill,
212      work stoppage, computer failure or malfunction, or any and all
213      other commercial damages or losses), even if such Contributor
214      has been advised of the possibility of such damages.
215
216   9. Accepting Warranty or Additional Liability. While redistributing
217      the Work or Derivative Works thereof, You may choose to offer,
218      and charge a fee for, acceptance of support, warranty, indemnity,
219      or other liability obligations and/or rights consistent with this
220      License. However, in accepting such obligations, You may act only
221      on Your own behalf and on Your sole responsibility, not on behalf
222      of any other Contributor, and only if You agree to indemnify,
223      defend, and hold each Contributor harmless for any liability
224      incurred by, or claims asserted against, such Contributor by reason
225      of your accepting any such warranty or additional liability.
