GNU GENERAL PUBLIC LICENSE
'
3
Version 3, 29 June 2007
'
4
'
5
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
'
6
Everyone is permitted to copy and distribute verbatim copies
'
7
of this license document, but changing it is not allowed.
'
8
'
9
Preamble
'
10
'
11
The GNU General Public License is a free, copyleft license for
'
12
software and other kinds of works.
'
13
'
14
The licenses for most software and other practical works are designed
'
15
to take away your freedom to share and change the works. By contrast,
'
16
the GNU General Public License is intended to guarantee your freedom to
'
17
share and change all versions of a program--to make sure it remains free
'
18
software for all its users. We, the Free Software Foundation, use the
'
19
GNU General Public License for most of our software; it applies also to
'
20
any other work released this way by its authors. You can apply it to
'
21
your programs, too.
'
22
'
23
When we speak of free software, we are referring to freedom, not
'
24
price. Our General Public Licenses are designed to make sure that you
'
25
have the freedom to distribute copies of free software (and charge for
'
26
them if you wish), that you receive source code or can get it if you
'
27
want it, that you can change the software or use pieces of it in new
'
28
free programs, and that you know you can do these things.
'
29
'
30
To protect your rights, we need to prevent others from denying you
'
31
these rights or asking you to surrender the rights. Therefore, you have
'
32
certain responsibilities if you distribute copies of the software, or if
'
33
you modify it: responsibilities to respect the freedom of others.
'
34
'
35
For example, if you distribute copies of such a program, whether
'
36
gratis or for a fee, you must pass on to the recipients the same
'
37
freedoms that you received. You must make sure that they, too, receive
'
38
or can get the source code. And you must show them these terms so they
'
39
know their rights.
'
40
'
41
Developers that use the GNU GPL protect your rights with two steps:
'
42
(1) assert copyright on the software, and (2) offer you this License
'
43
giving you legal permission to copy, distribute and/or modify it.
'
44
'
45
For the developers' and authors' protection, the GPL clearly explains
'
46
that there is no warranty for this free software. For both users' and
'
47
authors' sake, the GPL requires that modified versions be marked as
'
48
changed, so that their problems will not be attributed erroneously to
'
49
authors of previous versions.
'
50
'
51
Some devices are designed to deny users access to install or run
'
52
modified versions of the software inside them, although the manufacturer
'
53
can do so. This is fundamentally incompatible with the aim of
'
54
protecting users' freedom to change the software. The systematic
'
55
pattern of such abuse occurs in the area of products for individuals to
'
56
use, which is precisely where it is most unacceptable. Therefore, we
'
57
have designed this version of the GPL to prohibit the practice for those
'
58
products. If such problems arise substantially in other domains, we
'
59
stand ready to extend this provision to those domains in future versions
'
60
of the GPL, as needed to protect the freedom of users.
'
61
'
62
Finally, every program is threatened constantly by software patents.
'
63
States should not allow patents to restrict development and use of
'
64
software on general-purpose computers, but in those that do, we wish to
'
65
avoid the special danger that patents applied to a free program could
'
66
make it effectively proprietary. To prevent this, the GPL assures that
'
67
patents cannot be used to render the program non-free.
'
68
'
69
The precise terms and conditions for copying, distribution and
'
70
modification follow.
'
71
'
72
TERMS AND CONDITIONS
'
73
'
74
0. Definitions.
'
75
'
76
"This License" refers to version 3 of the GNU General Public License.
'
77
'
78
"Copyright" also means copyright-like laws that apply to other kinds of
'
79
works, such as semiconductor masks.
'
80
'
81
"The Program" refers to any copyrightable work licensed under this
'
82
License. Each licensee is addressed as "you". "Licensees" and
'
83
"recipients" may be individuals or organizations.
'
84
'
85
To "modify" a work means to copy from or adapt all or part of the work
'
86
in a fashion requiring copyright permission, other than the making of an
'
87
exact copy. The resulting work is called a "modified version" of the
'
88
earlier work or a work "based on" the earlier work.
'
89
'
90
A "covered work" means either the unmodified Program or a work based
'
91
on the Program.
'
92
'
93
To "propagate" a work means to do anything with it that, without
'
94
permission, would make you directly or secondarily liable for
'
95
infringement under applicable copyright law, except executing it on a
'
96
computer or modifying a private copy. Propagation includes copying,
'
97
distribution (with or without modification), making available to the
'
98
public, and in some countries other activities as well.
'
99
'
100
To "convey" a work means any kind of propagation that enables other
'
101
parties to make or receive copies. Mere interaction with a user through
'
102
a computer network, with no transfer of a copy, is not conveying.
'
103
'
104
An interactive user interface displays "Appropriate Legal Notices"
'
105
to the extent that it includes a convenient and prominently visible
'
106
feature that (1) displays an appropriate copyright notice, and (2)
'
107
tells the user that there is no warranty for the work (except to the
'
108
extent that warranties are provided), that licensees may convey the
'
109
work under this License, and how to view a copy of this License. If
'
110
the interface presents a list of user commands or options, such as a
'
111
menu, a prominent item in the list meets this criterion.
'
112
'
113
1. Source Code.
'
114
'
115
The "source code" for a work means the preferred form of the work
'
116
for making modifications to it. "Object code" means any non-source
'
117
form of a work.
'
118
'
119
A "Standard Interface" means an interface that either is an official
'
120
standard defined by a recognized standards body, or, in the case of
'
121
interfaces specified for a particular programming language, one that
'
122
is widely used among developers working in that language.
'
123
'
124
The "System Libraries" of an executable work include anything, other
'
125
than the work as a whole, that (a) is included in the normal form of
'
126
packaging a Major Component, but which is not part of that Major
'
127
Component, and (b) serves only to enable use of the work with that
'
128
Major Component, or to implement a Standard Interface for which an
'
129
implementation is available to the public in source code form. A
'
130
"Major Component", in this context, means a major essential component
'
131
(kernel, window system, and so on) of the specific operating system
'
132
(if any) on which the executable work runs, or a compiler used to
'
133
produce the work, or an object code interpreter used to run it.
'
134
'
135
The "Corresponding Source" for a work in object code form means all
'
136
the source code needed to generate, install, and (for an executable
'
137
work) run the object code and to modify the work, including scripts to
'
138
control those activities. However, it does not include the work's
'
139
System Libraries, or general-purpose tools or generally available free
'
140
programs which are used unmodified in performing those activities but
'
141
which are not part of the work. For example, Corresponding Source
'
142
includes interface definition files associated with source files for
'
143
the work, and the source code for shared libraries and dynamically
'
144
linked subprograms that the work is specifically designed to require,
'
145
such as by intimate data communication or control flow between those
'
146
subprograms and other parts of the work.
'
147
'
148
The Corresponding Source need not include anything that users
'
149
can regenerate automatically from other parts of the Corresponding
'
150
Source.
'
151
'
152
The Corresponding Source for a work in source code form is that
'
153
same work.
'
154
'
155
2. Basic Permissions.
'
156
'
157
All rights granted under this License are granted for the term of
'
158
copyright on the Program, and are irrevocable provided the stated
'
159
conditions are met. This License explicitly affirms your unlimited
'
160
permission to run the unmodified Program. The output from running a
'
161
covered work is covered by this License only if the output, given its
'
162
content, constitutes a covered work. This License acknowledges your
'
163
rights of fair use or other equivalent, as provided by copyright law.
'
164
'
165
You may make, run and propagate covered works that you do not
'
166
convey, without conditions so long as your license otherwise remains
'
167
in force. You may convey covered works to others for the sole purpose
'
168
of having them make modifications exclusively for you, or provide you
'
169
with facilities for running those works, provided that you comply with
'
170
the terms of this License in conveying all material for which you do
'
171
not control copyright. Those thus making or running the covered works
'
172
for you must do so exclusively on your behalf, under your direction
'
173
and control, on terms that prohibit them from making any copies of
'
174
your copyrighted material outside their relationship with you.
'
175
'
176
Conveying under any other circumstances is permitted solely under
'
177
the conditions stated below. Sublicensing is not allowed; section 10
'
178
makes it unnecessary.
'
179
'
180
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
'
181
'
182
No covered work shall be deemed part of an effective technological
'
183
measure under any applicable law fulfilling obligations under article
'
184
11 of the WIPO copyright treaty adopted on 20 December 1996, or
'
185
similar laws prohibiting or restricting circumvention of such
'
186
measures.
'
187
'
188
When you convey a covered work, you waive any legal power to forbid
'
189
circumvention of technological measures to the extent such circumvention
'
190
is effected by exercising rights under this License with respect to
'
191
the covered work, and you disclaim any intention to limit operation or
'
192
modification of the work as a means of enforcing, against the work's
'
193
users, your or third parties' legal rights to forbid circumvention of
'
194
technological measures.
'
195
'
196
4. Conveying Verbatim Copies.
'
197
'
198
You may convey verbatim copies of the Program's source code as you
'
199
receive it, in any medium, provided that you conspicuously and
'
200
appropriately publish on each copy an appropriate copyright notice;
'
201
keep intact all notices stating that this License and any
'
202
non-permissive terms added in accord with section 7 apply to the code;
'
203
keep intact all notices of the absence of any warranty; and give all
'
204
recipients a copy of this License along with the Program.
'
205
'
206
You may charge any price or no price for each copy that you convey,
'
207
and you may offer support or warranty protection for a fee.
'
208
'
209
5. Conveying Modified Source Versions.
'
210
'
211
You may convey a work based on the Program, or the modifications to
'
212
produce it from the Program, in the form of source code under the
'
213
terms of section 4, provided that you also meet all of these conditions:
'
214
'
215
a) The work must carry prominent notices stating that you modified
'
216
it, and giving a relevant date.
'
217
'
218
b) The work must carry prominent notices stating that it is
'
219
released under this License and any conditions added under section
'
220
7. This requirement modifies the requirement in section 4 to
'
221
"keep intact all notices".
'
222
'
223
c) You must license the entire work, as a whole, under this
'
224
License to anyone who comes into possession of a copy. This
'
225
License will therefore apply, along with any applicable section 7
'
226
additional terms, to the whole of the work, and all its parts,
'
227
regardless of how they are packaged. This License gives no
'
228
permission to license the work in any other way, but it does not
'
229
invalidate such permission if you have separately received it.
'
230
'
231
d) If the work has interactive user interfaces, each must display
'
232
Appropriate Legal Notices; however, if the Program has interactive
'
233
interfaces that do not display Appropriate Legal Notices, your
'
234
work need not make them do so.
'
235
'
236
A compilation of a covered work with other separate and independent
'
237
works, which are not by their nature extensions of the covered work,
'
238
and which are not combined with it such as to form a larger program,
'
239
in or on a volume of a storage or distribution medium, is called an
'
240
"aggregate" if the compilation and its resulting copyright are not
'
241
used to limit the access or legal rights of the compilation's users
'
242
beyond what the individual works permit. Inclusion of a covered work
'
243
in an aggregate does not cause this License to apply to the other
'
244
parts of the aggregate.
'
245
'
246
6. Conveying Non-Source Forms.
'
247
'
248
You may convey a covered work in object code form under the terms
'
249
of sections 4 and 5, provided that you also convey the
'
250
machine-readable Corresponding Source under the terms of this License,
'
251
in one of these ways:
'
252
'
253
a) Convey the object code in, or embodied in, a physical product
'
254
(including a physical distribution medium), accompanied by the
'
255
Corresponding Source fixed on a durable physical medium
'
256
customarily used for software interchange.
'
257
'
258
b) Convey the object code in, or embodied in, a physical product
'
259
(including a physical distribution medium), accompanied by a
'
260
written offer, valid for at least three years and valid for as
'
261
long as you offer spare parts or customer support for that product
'
262
model, to give anyone who possesses the object code either (1) a
'
263
copy of the Corresponding Source for all the software in the
'
264
product that is covered by this License, on a durable physical
'
265
medium customarily used for software interchange, for a price no
'
266
more than your reasonable cost of physically performing this
'
267
conveying of source, or (2) access to copy the
'
268
Corresponding Source from a network server at no charge.
'
269
'
270
c) Convey individual copies of the object code with a copy of the
'
271
written offer to provide the Corresponding Source. This
'
272
alternative is allowed only occasionally and noncommercially, and
'
273
only if you received the object code with such an offer, in accord
'
274
with subsection 6b.
'
275
'
276
d) Convey the object code by offering access from a designated
'
277
place (gratis or for a charge), and offer equivalent access to the
'
278
Corresponding Source in the same way through the same place at no
'
279
further charge. You need not require recipients to copy the
'
280
Corresponding Source along with the object code. If the place to
'
281
copy the object code is a network server, the Corresponding Source
'
282
may be on a different server (operated by you or a third party)
'
283
that supports equivalent copying facilities, provided you maintain
'
284
clear directions next to the object code saying where to find the
'
285
Corresponding Source. Regardless of what server hosts the
'
286
Corresponding Source, you remain obligated to ensure that it is
'
287
available for as long as needed to satisfy these requirements.
'
288
'
289
e) Convey the object code using peer-to-peer transmission, provided
'
290
you inform other peers where the object code and Corresponding
'
291
Source of the work are being offered to the general public at no
'
292
charge under subsection 6d.
'
293
'
294
A separable portion of the object code, whose source code is excluded
'
295
from the Corresponding Source as a System Library, need not be
'
296
included in conveying the object code work.
'
297
'
298
A "User Product" is either (1) a "consumer product", which means any
'
299
tangible personal property which is normally used for personal, family,
'
300
or household purposes, or (2) anything designed or sold for incorporation
'
301
into a dwelling. In determining whether a product is a consumer product,
'
302
doubtful cases shall be resolved in favor of coverage. For a particular
'
303
product received by a particular user, "normally used" refers to a
'
304
typical or common use of that class of product, regardless of the status
'
305
of the particular user or of the way in which the particular user
'
306
actually uses, or expects or is expected to use, the product. A product
'
307
is a consumer product regardless of whether the product has substantial
'
308
commercial, industrial or non-consumer uses, unless such uses represent
'
309
the only significant mode of use of the product.
'
310
'
311
"Installation Information" for a User Product means any methods,
'
312
procedures, authorization keys, or other information required to install
'
313
and execute modified versions of a covered work in that User Product from
'
314
a modified version of its Corresponding Source. The information must
'
315
suffice to ensure that the continued functioning of the modified object
'
316
code is in no case prevented or interfered with solely because
'
317
modification has been made.
'
318
'
319
If you convey an object code work under this section in, or with, or
'
320
specifically for use in, a User Product, and the conveying occurs as
'
321
part of a transaction in which the right of possession and use of the
'
322
User Product is transferred to the recipient in perpetuity or for a
'
323
fixed term (regardless of how the transaction is characterized), the
'
324
Corresponding Source conveyed under this section must be accompanied
'
325
by the Installation Information. But this requirement does not apply
'
326
if neither you nor any third party retains the ability to install
'
327
modified object code on the User Product (for example, the work has
'
328
been installed in ROM).
'
329
'
330
The requirement to provide Installation Information does not include a
'
331
requirement to continue to provide support service, warranty, or updates
'
332
for a work that has been modified or installed by the recipient, or for
'
333
the User Product in which it has been modified or installed. Access to a
'
334
network may be denied when the modification itself materially and
'
335
adversely affects the operation of the network or violates the rules and
'
336
protocols for communication across the network.
'
337
'
338
Corresponding Source conveyed, and Installation Information provided,
'
339
in accord with this section must be in a format that is publicly
'
340
documented (and with an implementation available to the public in
'
341
source code form), and must require no special password or key for
'
342
unpacking, reading or copying.
'
343
'
344
7. Additional Terms.
'
345
'
346
"Additional permissions" are terms that supplement the terms of this
'
347
License by making exceptions from one or more of its conditions.
'
348
Additional permissions that are applicable to the entire Program shall
'
349
be treated as though they were included in this License, to the extent
'
350
that they are valid under applicable law. If additional permissions
'
351
apply only to part of the Program, that part may be used separately
'
352
under those permissions, but the entire Program remains governed by
'
353
this License without regard to the additional permissions.
'
354
'
355
When you convey a copy of a covered work, you may at your option
'
356
remove any additional permissions from that copy, or from any part of
'
357
it. (Additional permissions may be written to require their own
'
358
removal in certain cases when you modify the work.) You may place
'
359
additional permissions on material, added by you to a covered work,
'
360
for which you have or can give appropriate copyright permission.
'
361
'
362
Notwithstanding any other provision of this License, for material you
'
363
add to a covered work, you may (if authorized by the copyright holders of
'
364
that material) supplement the terms of this License with terms:
'
365
'
366
a) Disclaiming warranty or limiting liability differently from the
'
367
terms of sections 15 and 16 of this License; or
'
368
'
369
b) Requiring preservation of specified reasonable legal notices or
'
370
author attributions in that material or in the Appropriate Legal
'
371
Notices displayed by works containing it; or
'
372
'
373
c) Prohibiting misrepresentation of the origin of that material, or
'
374
requiring that modified versions of such material be marked in
'
375
reasonable ways as different from the original version; or
'
376
'
377
d) Limiting the use for publicity purposes of names of licensors or
'
378
authors of the material; or
'
379
'
380
e) Declining to grant rights under trademark law for use of some
'
381
trade names, trademarks, or service marks; or
'
382
'
383
f) Requiring indemnification of licensors and authors of that
'
384
material by anyone who conveys the material (or modified versions of
'
385
it) with contractual assumptions of liability to the recipient, for
'
386
any liability that these contractual assumptions directly impose on
'
387
those licensors and authors.
'
388
'
389
All other non-permissive additional terms are considered "further
'
390
restrictions" within the meaning of section 10. If the Program as you
'
391
received it, or any part of it, contains a notice stating that it is
'
392
governed by this License along with a term that is a further
'
393
restriction, you may remove that term. If a license document contains
'
394
a further restriction but permits relicensing or conveying under this
'
395
License, you may add to a covered work material governed by the terms
'
396
of that license document, provided that the further restriction does
'
397
not survive such relicensing or conveying.
'
398
'
399
If you add terms to a covered work in accord with this section, you
'
400
must place, in the relevant source files, a statement of the
'
401
additional terms that apply to those files, or a notice indicating
'
402
where to find the applicable terms.
'
403
'
404
Additional terms, permissive or non-permissive, may be stated in the
'
405
form of a separately written license, or stated as exceptions;
'
406
the above requirements apply either way.
'
407
'
408
8. Termination.
'
409
'
410
You may not propagate or modify a covered work except as expressly
'
411
provided under this License. Any attempt otherwise to propagate or
'
412
modify it is void, and will automatically terminate your rights under
'
413
this License (including any patent licenses granted under the third
'
414
paragraph of section 11).
'
415
'
416
However, if you cease all violation of this License, then your
'
417
license from a particular copyright holder is reinstated (a)
'
418
provisionally, unless and until the copyright holder explicitly and
'
419
finally terminates your license, and (b) permanently, if the copyright
'
420
holder fails to notify you of the violation by some reasonable means
'
421
prior to 60 days after the cessation.
'
422
'
423
Moreover, your license from a particular copyright holder is
'
424
reinstated permanently if the copyright holder notifies you of the
'
425
violation by some reasonable means, this is the first time you have
'
426
received notice of violation of this License (for any work) from that
'
427
copyright holder, and you cure the violation prior to 30 days after
'
428
your receipt of the notice.
'
429
'
430
Termination of your rights under this section does not terminate the
'
431
licenses of parties who have received copies or rights from you under
'
432
this License. If your rights have been terminated and not permanently
'
433
reinstated, you do not qualify to receive new licenses for the same
'
434
material under section 10.
'
435
'
436
9. Acceptance Not Required for Having Copies.
'
437
'
438
You are not required to accept this License in order to receive or
'
439
run a copy of the Program. Ancillary propagation of a covered work
'
440
occurring solely as a consequence of using peer-to-peer transmission
'
441
to receive a copy likewise does not require acceptance. However,
'
442
nothing other than this License grants you permission to propagate or
'
443
modify any covered work. These actions infringe copyright if you do
'
444
not accept this License. Therefore, by modifying or propagating a
'
445
covered work, you indicate your acceptance of this License to do so.
'
446
'
447
10. Automatic Licensing of Downstream Recipients.
'
448
'
449
Each time you convey a covered work, the recipient automatically
'
450
receives a license from the original licensors, to run, modify and
'
451
propagate that work, subject to this License. You are not responsible
'
452
for enforcing compliance by third parties with this License.
'
453
'
454
An "entity transaction" is a transaction transferring control of an
'
455
organization, or substantially all assets of one, or subdividing an
'
456
organization, or merging organizations. If propagation of a covered
'
457
work results from an entity transaction, each party to that
'
458
transaction who receives a copy of the work also receives whatever
'
459
licenses to the work the party's predecessor in interest had or could
'
460
give under the previous paragraph, plus a right to possession of the
'
461
Corresponding Source of the work from the predecessor in interest, if
'
462
the predecessor has it or can get it with reasonable efforts.
'
463
'
464
You may not impose any further restrictions on the exercise of the
'
465
rights granted or affirmed under this License. For example, you may
'
466
not impose a license fee, royalty, or other charge for exercise of
'
467
rights granted under this License, and you may not initiate litigation
'
468
(including a cross-claim or counterclaim in a lawsuit) alleging that
'
469
any patent claim is infringed by making, using, selling, offering for
'
470
sale, or importing the Program or any portion of it.
'
471
'
472
11. Patents.
'
473
'
474
A "contributor" is a copyright holder who authorizes use under this
'
475
License of the Program or a work on which the Program is based. The
'
476
work thus licensed is called the contributor's "contributor version".
'
477
'
478
A contributor's "essential patent claims" are all patent claims
'
479
owned or controlled by the contributor, whether already acquired or
'
480
hereafter acquired, that would be infringed by some manner, permitted
'
481
by this License, of making, using, or selling its contributor version,
'
482
but do not include claims that would be infringed only as a
'
483
consequence of further modification of the contributor version. For
'
484
purposes of this definition, "control" includes the right to grant
'
485
patent sublicenses in a manner consistent with the requirements of
'
486
this License.
'
487
'
488
Each contributor grants you a non-exclusive, worldwide, royalty-free
'
489
patent license under the contributor's essential patent claims, to
'
490
make, use, sell, offer for sale, import and otherwise run, modify and
'
491
propagate the contents of its contributor version.
'
492
'
493
In the following three paragraphs, a "patent license" is any express
'
494
agreement or commitment, however denominated, not to enforce a patent
'
495
(such as an express permission to practice a patent or covenant not to
'
496
sue for patent infringement). To "grant" such a patent license to a
'
497
party means to make such an agreement or commitment not to enforce a
'
498
patent against the party.
'
499
'
500
If you convey a covered work, knowingly relying on a patent license,
'
501
and the Corresponding Source of the work is not available for anyone
'
502
to copy, free of charge and under the terms of this License, through a
'
503
publicly available network server or other readily accessible means,
'
504
then you must either (1) cause the Corresponding Source to be so
'
505
available, or (2) arrange to deprive yourself of the benefit of the
'
506
patent license for this particular work, or (3) arrange, in a manner
'
507
consistent with the requirements of this License, to extend the patent
'
508
license to downstream recipients. "Knowingly relying" means you have
'
509
actual knowledge that, but for the patent license, your conveying the
'
510
covered work in a country, or your recipient's use of the covered work
'
511
in a country, would infringe one or more identifiable patents in that
'
512
country that you have reason to believe are valid.
'
513
'
514
If, pursuant to or in connection with a single transaction or
'
515
arrangement, you convey, or propagate by procuring conveyance of, a
'
516
covered work, and grant a patent license to some of the parties
'
517
receiving the covered work authorizing them to use, propagate, modify
'
518
or convey a specific copy of the covered work, then the patent license
'
519
you grant is automatically extended to all recipients of the covered
'
520
work and works based on it.
'
521
'
522
A patent license is "discriminatory" if it does not include within
'
523
the scope of its coverage, prohibits the exercise of, or is
'
524
conditioned on the non-exercise of one or more of the rights that are
'
525
specifically granted under this License. You may not convey a covered
'
526
work if you are a party to an arrangement with a third party that is
'
527
in the business of distributing software, under which you make payment
'
528
to the third party based on the extent of your activity of conveying
'
529
the work, and under which the third party grants, to any of the
'
530
parties who would receive the covered work from you, a discriminatory
'
531
patent license (a) in connection with copies of the covered work
'
532
conveyed by you (or copies made from those copies), or (b) primarily
'
533
for and in connection with specific products or compilations that
'
534
contain the covered work, unless you entered into that arrangement,
'
535
or that patent license was granted, prior to 28 March 2007.
'
536
'
537
Nothing in this License shall be construed as excluding or limiting
'
538
any implied license or other defenses to infringement that may
'
539
otherwise be available to you under applicable patent law.
'
540
'
541
12. No Surrender of Others' Freedom.
'
542
'
543
If conditions are imposed on you (whether by court order, agreement or
'
544
otherwise) that contradict the conditions of this License, they do not
'
545
excuse you from the conditions of this License. If you cannot convey a
'
546
covered work so as to satisfy simultaneously your obligations under this
'
547
License and any other pertinent obligations, then as a consequence you may
'
548
not convey it at all. For example, if you agree to terms that obligate you
'
549
to collect a royalty for further conveying from those to whom you convey
'
550
the Program, the only way you could satisfy both those terms and this
'
551
License would be to refrain entirely from conveying the Program.
'
552
'
553
13. Use with the GNU Affero General Public License.
'
554
'
555
Notwithstanding any other provision of this License, you have
'
556
permission to link or combine any covered work with a work licensed
'
557
under version 3 of the GNU Affero General Public License into a single
'
558
combined work, and to convey the resulting work. The terms of this
'
559
License will continue to apply to the part which is the covered work,
'
560
but the special requirements of the GNU Affero General Public License,
'
561
section 13, concerning interaction through a network will apply to the
'
562
combination as such.
'
563
'
564
14. Revised Versions of this License.
'
565
'
566
The Free Software Foundation may publish revised and/or new versions of
'
567
the GNU General Public License from time to time. Such new versions will
'
568
be similar in spirit to the present version, but may differ in detail to
'
569
address new problems or concerns.
'
570
'
571
Each version is given a distinguishing version number. If the
'
572
Program specifies that a certain numbered version of the GNU General
'
573
Public License "or any later version" applies to it, you have the
'
574
option of following the terms and conditions either of that numbered
'
575
version or of any later version published by the Free Software
'
576
Foundation. If the Program does not specify a version number of the
'
577
GNU General Public License, you may choose any version ever published
'
578
by the Free Software Foundation.
'
579
'
580
If the Program specifies that a proxy can decide which future
'
581
versions of the GNU General Public License can be used, that proxy's
'
582
public statement of acceptance of a version permanently authorizes you
'
583
to choose that version for the Program.
'
584
'
585
Later license versions may give you additional or different
'
586
permissions. However, no additional obligations are imposed on any
'
587
author or copyright holder as a result of your choosing to follow a
'
588
later version.
'
589
'
590
15. Disclaimer of Warranty.
'
591
'
592
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
'
593
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
'
594
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
'
595
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
'
596
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
'
597
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
'
598
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
'
599
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
'
600
'
601
16. Limitation of Liability.
'
602
'
603
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
'
604
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
'
605
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
'
606
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
'
607
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
'
608
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
'
609
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
'
610
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
'
611
SUCH DAMAGES.
'
612
'
613
17. Interpretation of Sections 15 and 16.
'
614
'
615
If the disclaimer of warranty and limitation of liability provided
'
616
above cannot be given local legal effect according to their terms,
'
617
reviewing courts shall apply local law that most closely approximates
'
618
an absolute waiver of all civil liability in connection with the
'
619
Program, unless a warranty or assumption of liability accompanies a
'
620
copy of the Program in return for a fee.
'
621
'
622
END OF TERMS AND CONDITIONS
'
623
'
624
How to Apply These Terms to Your New Programs
'
625
'
626
If you develop a new program, and you want it to be of the greatest
'
627
possible use to the public, the best way to achieve this is to make it
'
628
free software which everyone can redistribute and change under these terms.
'
629
'
630
To do so, attach the following notices to the program. It is safest
'
631
to attach them to the start of each source file to most effectively
'
632
state the exclusion of warranty; and each file should have at least
'
633
the "copyright" line and a pointer to where the full notice is found.
'
634
'
635
<one line to give the program's name and a brief idea of what it does.>
'
636
Copyright (C) <year> <name of author>
'
637
'
638
This program is free software: you can redistribute it and/or modify
'
639
it under the terms of the GNU General Public License as published by
'
640
the Free Software Foundation, either version 3 of the License, or
'
641
(at your option) any later version.
'
642
'
643
This program is distributed in the hope that it will be useful,
'
644
but WITHOUT ANY WARRANTY; without even the implied warranty of
'
645
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
'
646
GNU General Public License for more details.
'
647
'
648
You should have received a copy of the GNU General Public License
'
649
along with this program. If not, see <http://www.gnu.org/licenses/>.
'
650
'
651
Also add information on how to contact you by electronic and paper mail.
'
652
'
653
If the program does terminal interaction, make it output a short
'
654
notice like this when it starts in an interactive mode:
'
655
'
656
<program> Copyright (C) <year> <name of author>
'
657
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
'
658
This is free software, and you are welcome to redistribute it
'
659
under certain conditions; type `show c' for details.
'
660
'
661
The hypothetical commands `show w' and `show c' should show the appropriate
'
662
parts of the General Public License. Of course, your program's commands
'
663
might be different; for a GUI interface, you would use an "about box".
'
664
'
665
You should also get your employer (if you work as a programmer) or school,
'
666
if any, to sign a "copyright disclaimer" for the program, if necessary.
'
667

'
669
'
670
The GNU General Public License does not permit incorporating your program
'
671
into proprietary programs. If your program is a subroutine library, you
'
672
may consider it more useful to permit linking proprietary applications with
'
673
the library. If this is what you want to do, use the GNU Lesser General
'
674
Public License instead of this License. But first, please read
'
675
