+
work which Apple Inc. ("Apple") makes publicly available and which contains a
15
+
notice placed by Apple identifying such program or work as "Original Code" and
16
+
stating that it is subject to the terms of this Apple Public Source License

22
+
the Original Code, but only to the extent necessary to use, reproduce and/or
23
+

+
You are the grantor of rights, (i) claims of patents that are now or hereafter

71
+
2. Permitted Uses; Conditions & Restrictions. Subject to the terms and
72
+
conditions of this License, Apple hereby grants You, effective on the date You
73
+
accept this License and download the Original Code, a world-wide, royalty-free,
74
+
non-exclusive license, to the extent of Apple's Applicable Patent Rights and
75
+
copyrights covering the Original Code, to do the following:
76
+
77
+
2.1 Unmodified Code. You may use, reproduce, display, perform, internally
78
+
distribute within Your organization, and Externally Deploy verbatim, unmodified
79
+
copies of the Original Code, for commercial or non-commercial purposes,
80
+
provided that in each instance:
81
+
82
+
(a) You must retain and reproduce in all copies of Original Code the
83
+
copyright and other proprietary notices and disclaimers of Apple as they appear
84
+
in the Original Code, and keep intact all notices in the Original Code that
85
+
refer to this License; and
86
+
87
+
(b) You must include a copy of this License with every copy of Source Code
88
+
of Covered Code and documentation You distribute or Externally Deploy, and You
89
+
may not offer or impose any terms on such Source Code that alter or restrict
90
+
this License or the recipients' rights hereunder, except as permitted under
91
+
Section 6.
92
+
93
+
2.2 Modified Code. You may modify Covered Code and use, reproduce,
94
+
display, perform, internally distribute within Your organization, and
95
+
Externally Deploy Your Modifications and Covered Code, for commercial or
96
+
non-commercial purposes, provided that in each instance You also meet all of
97
+
these conditions:
98
+
99
+
(a) You must satisfy all the conditions of Section 2.1 with respect to the
100
+
Source Code of the Covered Code;
101
+
102
+
(b) You must duplicate, to the extent it does not already exist, the notice
103
+
in Exhibit A in each file of the Source Code of all Your Modifications, and
104
+
cause the modified files to carry prominent notices stating that You changed
105
+
the files and the date of any change; and
106
+
107
+
(c) If You Externally Deploy Your Modifications, You must make Source Code
108
+
of all Your Externally Deployed Modifications either available to those to whom
109
+
You have Externally Deployed Your Modifications, or publicly available. Source
110
+
Code of Your Externally Deployed Modifications must be released under the terms
111
+
set forth in this License, including the license grants set forth in Section 3
112
+
below, for as long as you Externally Deploy the Covered Code or twelve (12)
113
+
months from the date of initial External Deployment, whichever is longer. You
114
+
should preferably distribute the Source Code of Your Externally Deployed
115
+
Modifications electronically (e.g. download from a web site).
116
+
117
+
2.3 Distribution of Executable Versions. In addition, if You Externally
118
+
Deploy Covered Code (Original Code and/or Modifications) in object code,
119
+
executable form only, You must include a prominent notice, in the code itself
120
+
as well as in related documentation, stating that Source Code of the Covered
121
+
Code is available under the terms of this License with information on how and
122
+
where to obtain such Source Code.
123
+
124
+
2.4 Third Party Rights. You expressly acknowledge and agree that although
125
+
Apple and each Contributor grants the licenses to their respective portions of
126
+
the Covered Code set forth herein, no assurances are provided by Apple or any
127
+
Contributor that the Covered Code does not infringe the patent or other
128
+
intellectual property rights of any other entity. Apple and each Contributor
129
+
disclaim any liability to You for claims brought by any other entity based on
130
+
infringement of intellectual property rights or otherwise. As a condition to
131
+
exercising the rights and licenses granted hereunder, You hereby assume sole
132
+
responsibility to secure any other intellectual property rights needed, if any.
133
+
For example, if a third party patent license is required to allow You to
134
+
distribute the Covered Code, it is Your responsibility to acquire that license
135
+
before distributing the Covered Code.
136
+
137
+
3. Your Grants. In consideration of, and as a condition to, the licenses
138
+
granted to You under this License, You hereby grant to any person or entity
139
+
receiving or distributing Covered Code under this License a non-exclusive,
140
+
royalty-free, perpetual, irrevocable license, under Your Applicable Patent
141
+
Rights and other intellectual property rights (other than patent) owned or
142
+
controlled by You, to use, reproduce, display, perform, modify, sublicense,
143
+
distribute and Externally Deploy Your Modifications of the same scope and
144
+
extent as Apple's licenses under Sections 2.1 and 2.2 above.
145
+
146
+
4. Larger Works. You may create a Larger Work by combining Covered Code
147
+
with other code not governed by the terms of this License and distribute the
148
+
Larger Work as a single product. In each such instance, You must make sure the
149
+
requirements of this License are fulfilled for the Covered Code or any portion
150
+
thereof.
151
+
152
+
5. Limitations on Patent License. Except as expressly stated in Section
153
+
2, no other patent rights, express or implied, are granted by Apple herein.
154
+
Modifications and/or Larger Works may require additional patent licenses from
155
+
Apple which Apple may grant in its sole discretion.
156
+
157
+
6. Additional Terms. You may choose to offer, and to charge a fee for,
158
+
warranty, support, indemnity or liability obligations and/or other rights
159
+
consistent with the scope of the license granted herein ("Additional Terms") to
160
+
one or more recipients of Covered Code. However, You may do so only on Your own
161
+
behalf and as Your sole responsibility, and not on behalf of Apple or any
162
+
Contributor. You must obtain the recipient's agreement that any such Additional
163
+
Terms are offered by You alone, and You hereby agree to indemnify, defend and
164
+
hold Apple and every Contributor harmless for any liability incurred by or
165
+
claims asserted against Apple or such Contributor by reason of any such
166
+
Additional Terms.
167
+
168
+
7. Versions of the License. Apple may publish revised and/or new versions
169
+
of this License from time to time. Each version will be given a distinguishing
170
+
version number. Once Original Code has been published under a particular
171
+
version of this License, You may continue to use it under the terms of that
172
+
version. You may also choose to use such Original Code under the terms of any
173
+
subsequent version of this License published by Apple. No one other than Apple
174
+
has the right to modify the terms applicable to Covered Code created under this
175
+
License.
176
+
177
+
8. NO WARRANTY OR SUPPORT. The Covered Code may contain in whole or in
178
+
part pre-release, untested, or not fully tested works. The Covered Code may
179
+
contain errors that could cause failures or loss of data, and may be incomplete
180
+
or contain inaccuracies. You expressly acknowledge and agree that use of the
181
+
Covered Code, or any portion thereof, is at Your sole and entire risk. THE
182
+
COVERED CODE IS PROVIDED "AS IS" AND WITHOUT WARRANTY, UPGRADES OR SUPPORT OF
183
+
ANY KIND AND APPLE AND APPLE'S LICENSOR(S) (COLLECTIVELY REFERRED TO AS "APPLE"
184
+
FOR THE PURPOSES OF SECTIONS 8 AND 9) AND ALL CONTRIBUTORS EXPRESSLY DISCLAIM
185
+
ALL WARRANTIES AND/OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT
186
+
LIMITED TO, THE IMPLIED WARRANTIES AND/OR CONDITIONS OF MERCHANTABILITY, OF
187
+
SATISFACTORY QUALITY, OF FITNESS FOR A PARTICULAR PURPOSE, OF ACCURACY, OF
188
+
QUIET ENJOYMENT, AND NONINFRINGEMENT OF THIRD PARTY RIGHTS. APPLE AND EACH
189
+
CONTRIBUTOR DOES NOT WARRANT AGAINST INTERFERENCE WITH YOUR ENJOYMENT OF THE
190
+
COVERED CODE, THAT THE FUNCTIONS CONTAINED IN THE COVERED CODE WILL MEET YOUR
191
+
REQUIREMENTS, THAT THE OPERATION OF THE COVERED CODE WILL BE UNINTERRUPTED OR
192
+
ERROR-FREE, OR THAT DEFECTS IN THE COVERED CODE WILL BE CORRECTED. NO ORAL OR
193
+
WRITTEN INFORMATION OR ADVICE GIVEN BY APPLE, AN APPLE AUTHORIZED
194
+
REPRESENTATIVE OR ANY CONTRIBUTOR SHALL CREATE A WARRANTY. You acknowledge
195
+
that the Covered Code is not intended for use in the operation of nuclear
196
+
facilities, aircraft navigation, communication systems, or air traffic control
197
+
machines in which case the failure of the Covered Code could lead to death,
198
+
personal injury, or severe physical or environmental damage.
199
+
200
+
9. LIMITATION OF LIABILITY. TO THE EXTENT NOT PROHIBITED BY LAW, IN NO
201
+
EVENT SHALL APPLE OR ANY CONTRIBUTOR BE LIABLE FOR ANY INCIDENTAL, SPECIAL,
202
+
INDIRECT OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO THIS LICENSE OR
203
+
YOUR USE OR INABILITY TO USE THE COVERED CODE, OR ANY PORTION THEREOF, WHETHER
204
+
UNDER A THEORY OF CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE), PRODUCTS
205
+
LIABILITY OR OTHERWISE, EVEN IF APPLE OR SUCH CONTRIBUTOR HAS BEEN ADVISED OF
206
+
THE POSSIBILITY OF SUCH DAMAGES AND NOTWITHSTANDING THE FAILURE OF ESSENTIAL
207
+
PURPOSE OF ANY REMEDY. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OF
208
+
LIABILITY OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT
209
+
APPLY TO YOU. In no event shall Apple's total liability to You for all damages
210
+
(other than as may be required by applicable law) under this License exceed the
211
+
amount of fifty dollars ($50.00).
212
+
213
+
10. Trademarks. This License does not grant any rights to use the
214
+
trademarks or trade names "Apple", "Mac", "Mac OS", "QuickTime", "QuickTime
215
+
Streaming Server" or any other trademarks, service marks, logos or trade names
216
+
belonging to Apple (collectively "Apple Marks") or to any trademark, service
217
+
mark, logo or trade name belonging to any Contributor. You agree not to use
218
+
any Apple Marks in or as part of the name of products derived from the Original
219
+
Code or to endorse or promote products derived from the Original Code other
220
+
than as expressly permitted by and in strict compliance at all times with
221
+
Apple's third party trademark usage guidelines which are posted at
222
+
http://www.apple.com/legal/guidelinesfor3rdparties.html.
223
+
224
+
11. Ownership. Subject to the licenses granted under this License, each
225
+
Contributor retains all rights, title and interest in and to any Modifications
226
+
made by such Contributor. Apple retains all rights, title and interest in and
227
+
to the Original Code and any Modifications made by or on behalf of Apple
228
+
("Apple Modifications"), and such Apple Modifications will not be automatically
229
+
subject to this License. Apple may, at its sole discretion, choose to license
230
+
such Apple Modifications under this License, or on different terms from those
231
+
contained in this License or may choose not to license them at all.
232
+
233
+
12. Termination.
234
+
235
+
12.1 Termination. This License and the rights granted hereunder will
236
+
terminate:
237
+
238
+
(a) automatically without notice from Apple if You fail to comply with any
239
+
term(s) of this License and fail to cure such breach within 30 days of becoming
240
+
aware of such breach;
241
+
(b) immediately in the event of the circumstances described in Section
242
+
13.5(b); or
243
+
(c) automatically without notice from Apple if You, at any time during the
244
+
term of this License, commence an action for patent infringement against Apple;
245
+
provided that Apple did not first commence an action for patent infringement
246
+
against You in that instance.
247
+
248
+
12.2 Effect of Termination. Upon termination, You agree to immediately stop
249
+
any further use, reproduction, modification, sublicensing and distribution of
250
+
the Covered Code. All sublicenses to the Covered Code which have been properly
251
+
granted prior to termination shall survive any termination of this License.
252
+
Provisions which, by their nature, should remain in effect beyond the
253
+
termination of this License shall survive, including but not limited to
254
+
Sections 3, 5, 8, 9, 10, 11, 12.2 and 13. No party will be liable to any other
255
+
for compensation, indemnity or damages of any sort solely as a result of
256
+
terminating this License in accordance with its terms, and termination of this
257
+
License will be without prejudice to any other right or remedy of any party.
258
+
259
+
13. Miscellaneous.
260
+
261
+
13.1 Government End Users. The Covered Code is a "commercial item" as
262
+
defined in FAR 2.101. Government software and technical data rights in the
263
+
Covered Code include only those rights customarily provided to the public as
264
+
defined in this License. This customary commercial license in technical data
265
+
and software is provided in accordance with FAR 12.211 (Technical Data) and
266
+
12.212 (Computer Software) and, for Department of Defense purchases, DFAR
267
+
252.227-7015 (Technical Data -- Commercial Items) and 227.7202-3 (Rights in
268
+
Commercial Computer Software or Computer Software Documentation). Accordingly,
269
+
all U.S. Government End Users acquire Covered Code with only those rights set
270
+
forth herein.
271
+
272
+
13.2 Relationship of Parties. This License will not be construed as
273
+
creating an agency, partnership, joint venture or any other form of legal
274
+
association between or among You, Apple or any Contributor, and You will not
275
+
represent to the contrary, whether expressly, by implication, appearance or
276
+
otherwise.
277
+
278
+
13.3 Independent Development. Nothing in this License will impair Apple's
279
+
right to acquire, license, develop, have others develop for it, market and/or
280
+
distribute technology or products that perform the same or similar functions
281
+
as, or otherwise compete with, Modifications, Larger Works, technology or
282
+
products that You may develop, produce, market or distribute.
283
+
284
+
13.4 Waiver; Construction. Failure by Apple or any Contributor to enforce
285
+
any provision of this License will not be deemed a waiver of future enforcement
286
+
of that or any other provision. Any law or regulation which provides that the
287
+
language of a contract shall be construed against the drafter will not apply to
288
+
this License.
289
+
290
+
13.5 Severability. (a) If for any reason a court of competent jurisdiction
291
+
finds any provision of this License, or portion thereof, to be unenforceable,
292
+
that provision of the License will be enforced to the maximum extent
293
+
permissible so as to effect the economic benefits and intent of the parties,
294
+
and the remainder of this License will continue in full force and effect. (b)
295
+
Notwithstanding the foregoing, if applicable law prohibits or restricts You
296
+
from fully and/or specifically complying with Sections 2 and/or 3 or prevents
297
+
the enforceability of either of those Sections, this License will immediately
298
+
terminate and You must immediately discontinue any use of the Covered Code and
299
+
destroy all copies of it that are in your possession or control.
300
+
301
+
13.6 Dispute Resolution. Any litigation or other dispute resolution between
302
+
You and Apple relating to this License shall take place in the Northern
303
+
District of California, and You and Apple hereby consent to the personal
304
+
jurisdiction of, and venue in, the state and federal courts within that
305
+
District with respect to this License. The application of the United Nations
306
+
Convention on Contracts for the International Sale of Goods is expressly
307
+
excluded.
308
+
309
+
13.7 Entire Agreement; Governing Law. This License constitutes the entire
310
+
agreement between the parties with respect to the subject matter hereof. This
311
+
License shall be governed by the laws of the United States and the State of
312
+
California, except that body of California law concerning conflicts of law.
313
+
314
+
Where You are located in the province of Quebec, Canada, the following clause
315
+
applies: The parties hereby confirm that they have requested that this License
316
+
and all related documents be drafted in English. Les parties ont exigé que le
317
+
présent contrat et tous les documents connexes soient rédigés en anglais.
