+ "Derivative Works" shall mean any work, whether in Source or Object
322
+ form, that is based on (or derived from) the Work and for which the
323
+ editorial revisions, annotations, elaborations, or other modifications
324
+ represent, as a whole, an original work of authorship. For the purposes
325
+ of this License, Derivative Works shall not include works that remain
326
+ separable from, or merely link (or bind by name) to the interfaces of,
327
+ the Work and Derivative Works thereof.
328
+
329
+ "Contribution" shall mean any work of authorship, including
330
+ the original version of the Work and any modifications or additions
331
+ to that Work or Derivative Works thereof, that is intentionally
332
+ submitted to Licensor for inclusion in the Work by the copyright owner
333
+ or by an individual or Legal Entity authorized to submit on behalf of
334
+ the copyright owner. For the purposes of this definition, "submitted"
335
+ means any form of electronic, verbal, or written communication sent
336
+ to the Licensor or its representatives, including but not limited to
337
+ communication on electronic mailing lists, source code control systems,
338
+ and issue tracking systems that are managed by, or on behalf of, the
339
+ Licensor for the purpose of discussing and improving the Work, but
340
+ excluding communication that is conspicuously marked or otherwise
341
+ designated in writing by the copyright owner as "Not a Contribution."
342
+
343
+ "Contributor" shall mean Licensor and any individual or Legal Entity
344
+ on behalf of whom a Contribution has been received by Licensor and
345
+ subsequently incorporated within the Work.
346
+
347
+ 2. Grant of Copyright License. Subject to the terms and conditions of
348
+ this License, each Contributor hereby grants to You a perpetual,
349
+ worldwide, non-exclusive, no-charge, royalty-free, irrevocable
350
+ copyright license to reproduce, prepare Derivative Works of,
351
+ publicly display, publicly perform, sublicense, and distribute the
352
+ Work and such Derivative Works in Source or Object form.
353
+
354
+ 3. Grant of Patent License. Subject to the terms and conditions of
355
+ this License, each Contributor hereby grants to You a perpetual,
356
+ worldwide, non-exclusive, no-charge, royalty-free, irrevocable
357
+ (except as stated in this section) patent license to make, have made,
358
+ use, offer to sell, sell, import, and otherwise transfer the Work,
359
+ where such license applies only to those patent claims licensable
360
+ by such Contributor that are necessarily infringed by their
361
+ Contribution(s) alone or by combination of their Contribution(s)
362
+ with the Work to which such Contribution(s) was submitted. If You
363
+ institute patent litigation against any entity (including a
364
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
365
+ or a Contribution incorporated within the Work constitutes direct
366
+ or contributory patent infringement, then any patent licenses
367
+ granted to You under this License for that Work shall terminate
368
+ as of the date such litigation is filed.
369
+
370
+ 4. Redistribution. You may reproduce and distribute copies of the
371
+ Work or Derivative Works thereof in any medium, with or without
372
+ modifications, and in Source or Object form, provided that You
373
+ meet the following conditions:
374
+
375
+ (a) You must give any other recipients of the Work or
376
+ Derivative Works a copy of this License; and
377
+
378
+ (b) You must cause any modified files to carry prominent notices
379
+ stating that You changed the files; and
380
+
381
+ (c) You must retain, in the Source form of any Derivative Works
382
+ that You distribute, all copyright, patent, trademark, and
383
+ attribution notices from the Source form of the Work,
384
+ excluding those notices that do not pertain to any part of
385
+ the Derivative Works; and
386
+
387
+ (d) If the Work includes a "NOTICE" text file as part of its
388
+ distribution, then any Derivative Works that You distribute must
389
+ include a readable copy of the attribution notices contained
390
+ within such NOTICE file, excluding those notices that do not
391
+ pertain to any part of the Derivative Works, in at least one
392
+ of the following places: within a NOTICE text file distributed
393
+ as part of the Derivative Works; within the Source form or
394
+ documentation, if provided along with the Derivative Works; or,
395
+ within a display generated by the Derivative Works, if and
396
+ wherever such third-party notices normally appear. The contents
397
+ of the NOTICE file are for informational purposes only and
398
+ do not modify the License. You may add Your own attribution
399
+ notices within Derivative Works that You distribute, alongside
400
+ or as an addendum to the NOTICE text from the Work, provided
401
+ that such additional attribution notices cannot be construed
402
+ as modifying the License.
403
+
404
+ You may add Your own copyright statement to Your modifications and
405
+ may provide additional or different license terms and conditions
406
+ for use, reproduction, or distribution of Your modifications, or
407
+ for any such Derivative Works as a whole, provided Your use,
408
+ reproduction, and distribution of the Work otherwise complies with
409
+ the conditions stated in this License.
410
+
411
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
412
+ any Contribution intentionally submitted for inclusion in the Work
413
+ by You to the Licensor shall be under the terms and conditions of
414
+ this License, without any additional terms or conditions.
415
+ Notwithstanding the above, nothing herein shall supersede or modify
416
+ the terms of any separate license agreement you may have executed
417
+ with Licensor regarding such Contributions.
418
+
419
+ 6. Trademarks. This License does not grant permission to use the trade
420
+ names, trademarks, service marks, or product names of the Licensor,
421
+ except as required for reasonable and customary use in describing the
422
+ origin of the Work and reproducing the content of the NOTICE file.
423
+
424
+ 7. Disclaimer of Warranty. Unless required by applicable law or
425
+ agreed to in writing, Licensor provides the Work (and each
426
+ Contributor provides its Contributions) on an "AS IS" BASIS,
427
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
428
+ implied, including, without limitation, any warranties or conditions
429
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
430
+ PARTICULAR PURPOSE. You are solely responsible for determining the
431
+ appropriateness of using or redistributing the Work and assume any
432
+ risks associated with Your exercise of permissions under this License.
433
+
434
+ 8. Limitation of Liability. In no event and under no legal theory,
435
+ whether in tort (including negligence), contract, or otherwise,
436
+ unless required by applicable law (such as deliberate and grossly
437
+ negligent acts) or agreed to in writing, shall any Contributor be
438
+ liable to You for damages, including any direct, indirect, special,
439
+ incidental, or consequential damages of any character arising as a
440
+ result of this License or out of the use or inability to use the
441
+ Work (including but not limited to damages for loss of goodwill,
442
+ work stoppage, computer failure or malfunction, or any and all
443
+ other commercial damages or losses), even if such Contributor
444
+ has been advised of the possibility of such damages.
445
+
446
+ 9. Accepting Warranty or Additional Liability. While redistributing
447
+ the Work or Derivative Works thereof, You may choose to offer,
448
+ and charge a fee for, acceptance of support, warranty, indemnity,
449
+ or other liability obligations and/or rights consistent with this
450
+ License. However, in accepting such obligations, You may act only
451
+ on Your own behalf and on Your sole responsibility, not on behalf
452
+ of any other Contributor, and only if You agree to indemnify,
453
+ defend, and hold each Contributor harmless for any liability
454
+ incurred by, or claims asserted against, such Contributor by reason
455
+ of your accepting any such warranty or additional liability.
