66
                    GNU GENERAL PUBLIC LICENSE
67
                       Version 3, 29 June 2007
68

69
 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
70
 Everyone is permitted to copy and distribute verbatim copies
71
 of this license document, but changing it is not allowed.
72

73
                            Preamble
74

75
  The GNU General Public License is a free, copyleft license for
76
software and other kinds of works.
77

78
  The licenses for most software and other practical works are designed
79
to take away your freedom to share and change the works.  By contrast,
80
the GNU General Public License is intended to guarantee your freedom to
81
share and change all versions of a program--to make sure it remains free
82
software for all its users.  We, the Free Software Foundation, use the
83
GNU General Public License for most of our software; it applies also to
84
any other work released this way by its authors.  You can apply it to
85
your programs, too.
86

87
  When we speak of free software, we are referring to freedom, not
88
price.  Our General Public Licenses are designed to make sure that you
89
have the freedom to distribute copies of free software (and charge for
90
them if you wish), that you receive source code or can get it if you
91
want it, that you can change the software or use pieces of it in new
92
free programs, and that you know you can do these things.
93

94
  To protect your rights, we need to prevent others from denying you
95
these rights or asking you to surrender the rights.  Therefore, you have
96
certain responsibilities if you distribute copies of the software, or if
97
you modify it: responsibilities to respect the freedom of others.
98

99
  For example, if you distribute copies of such a program, whether
100
gratis or for a fee, you must pass on to the recipients the same
101
freedoms that you received.  You must make sure that they, too, receive
102
or can get the source code.  And you must show them these terms so they
103
know their rights.
104

105
  Developers that use the GNU GPL protect your rights with two steps:
106
(1) assert copyright on the software, and (2) offer you this License
107
giving you legal permission to copy, distribute and/or modify it.
108

109
  For the developers' and authors' protection, the GPL clearly explains
110
that there is no warranty for this free software.  For both users' and
111
authors' sake, the GPL requires that modified versions be marked as
112
changed, so that their problems will not be attributed erroneously to
113
authors of previous versions.
114

115
  Some devices are designed to deny users access to install or run
116
modified versions of the software inside them, although the manufacturer
117
can do so.  This is fundamentally incompatible with the aim of
118
protecting users' freedom to change the software.  The systematic
119
pattern of such abuse occurs in the area of products for individuals to
120
use, which is precisely where it is most unacceptable.  Therefore, we
121
have designed this version of the GPL to prohibit the practice for those
122
products.  If such problems arise substantially in other domains, we
123
stand ready to extend this provision to those domains in future versions
124
of the GPL, as needed to protect the freedom of users.
125

126
  Finally, every program is threatened constantly by software patents.
127
States should not allow patents to restrict development and use of
128
software on general-purpose computers, but in those that do, we wish to
129
avoid the special danger that patents applied to a free program could
130
make it effectively proprietary.  To prevent this, the GPL assures that
131
patents cannot be used to render the program non-free.
132

133
  The precise terms and conditions for copying, distribution and
134
modification follow.
135

136
                       TERMS AND CONDITIONS
137

138
  0. Definitions.
139

140
  "This License" refers to version 3 of the GNU General Public License.
141

142
  "Copyright" also means copyright-like laws that apply to other kinds of
143
works, such as semiconductor masks.
144

145
  "The Program" refers to any copyrightable work licensed under this
146
License.  Each licensee is addressed as "you".  "Licensees" and
147
"recipients" may be individuals or organizations.
148

149
  To "modify" a work means to copy from or adapt all or part of the work
150
in a fashion requiring copyright permission, other than the making of an
151
exact copy.  The resulting work is called a "modified version" of the
152
earlier work or a work "based on" the earlier work.
153

154
  A "covered work" means either the unmodified Program or a work based
155
on the Program.
156

157
  To "propagate" a work means to do anything with it that, without
158
permission, would make you directly or secondarily liable for
159
infringement under applicable copyright law, except executing it on a
160
computer or modifying a private copy.  Propagation includes copying,
161
distribution (with or without modification), making available to the
162
public, and in some countries other activities as well.
163

164
  To "convey" a work means any kind of propagation that enables other
165
parties to make or receive copies.  Mere interaction with a user through
166
a computer network, with no transfer of a copy, is not conveying.
167

168
  An interactive user interface displays "Appropriate Legal Notices"
169
to the extent that it includes a convenient and prominently visible
170
feature that (1) displays an appropriate copyright notice, and (2)
171
tells the user that there is no warranty for the work (except to the
172
extent that warranties are provided), that licensees may convey the
173
work under this License, and how to view a copy of this License.  If
174
the interface presents a list of user commands or options, such as a
175
menu, a prominent item in the list meets this criterion.
176

177
  1. Source Code.
178

179
  The "source code" for a work means the preferred form of the work
180
for making modifications to it.  "Object code" means any non-source
181
form of a work.
182

183
  A "Standard Interface" means an interface that either is an official
184
standard defined by a recognized standards body, or, in the case of
185
interfaces specified for a particular programming language, one that
186
is widely used among developers working in that language.
187

188
  The "System Libraries" of an executable work include anything, other
189
than the work as a whole, that (a) is included in the normal form of
190
packaging a Major Component, but which is not part of that Major
191
Component, and (b) serves only to enable use of the work with that
192
Major Component, or to implement a Standard Interface for which an
193
implementation is available to the public in source code form.  A
194
"Major Component", in this context, means a major essential component
195
(kernel, window system, and so on) of the specific operating system
196
(if any) on which the executable work runs, or a compiler used to
197
produce the work, or an object code interpreter used to run it.
198

199
  The "Corresponding Source" for a work in object code form means all
200
the source code needed to generate, install, and (for an executable
201
work) run the object code and to modify the work, including scripts to
202
control those activities.  However, it does not include the work's
203
System Libraries, or general-purpose tools or generally available free
204
programs which are used unmodified in performing those activities but
205
which are not part of the work.  For example, Corresponding Source
206
includes interface definition files associated with source files for
207
the work, and the source code for shared libraries and dynamically
208
linked subprograms that the work is specifically designed to require,
209
such as by intimate data communication or control flow between those
210
subprograms and other parts of the work.
211

212
  The Corresponding Source need not include anything that users
213
can regenerate automatically from other parts of the Corresponding
214
Source.
215

216
  The Corresponding Source for a work in source code form is that
217
same work.
218

219
  2. Basic Permissions.
220

221
  All rights granted under this License are granted for the term of
222
copyright on the Program, and are irrevocable provided the stated
223
conditions are met.  This License explicitly affirms your unlimited
224
permission to run the unmodified Program.  The output from running a
225
covered work is covered by this License only if the output, given its
226
content, constitutes a covered work.  This License acknowledges your
227
rights of fair use or other equivalent, as provided by copyright law.
228

229
  You may make, run and propagate covered works that you do not
230
convey, without conditions so long as your license otherwise remains
231
in force.  You may convey covered works to others for the sole purpose
232
of having them make modifications exclusively for you, or provide you
233
with facilities for running those works, provided that you comply with
234
the terms of this License in conveying all material for which you do
235
not control copyright.  Those thus making or running the covered works
236
for you must do so exclusively on your behalf, under your direction
237
and control, on terms that prohibit them from making any copies of
238
your copyrighted material outside their relationship with you.
239

240
  Conveying under any other circumstances is permitted solely under
241
the conditions stated below.  Sublicensing is not allowed; section 10
242
makes it unnecessary.
243

244
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
245

246
  No covered work shall be deemed part of an effective technological
247
measure under any applicable law fulfilling obligations under article
248
11 of the WIPO copyright treaty adopted on 20 December 1996, or
249
similar laws prohibiting or restricting circumvention of such
250
measures.
251

252
  When you convey a covered work, you waive any legal power to forbid
253
circumvention of technological measures to the extent such circumvention
254
is effected by exercising rights under this License with respect to
255
the covered work, and you disclaim any intention to limit operation or
256
modification of the work as a means of enforcing, against the work's
257
users, your or third parties' legal rights to forbid circumvention of
258
technological measures.
259

260
  4. Conveying Verbatim Copies.
261

262
  You may convey verbatim copies of the Program's source code as you
263
receive it, in any medium, provided that you conspicuously and
264
appropriately publish on each copy an appropriate copyright notice;
265
keep intact all notices stating that this License and any
266
non-permissive terms added in accord with section 7 apply to the code;
267
keep intact all notices of the absence of any warranty; and give all
268
recipients a copy of this License along with the Program.
269

270
  You may charge any price or no price for each copy that you convey,
271
and you may offer support or warranty protection for a fee.
272

273
  5. Conveying Modified Source Versions.
274

275
  You may convey a work based on the Program, or the modifications to
276
produce it from the Program, in the form of source code under the
277
terms of section 4, provided that you also meet all of these conditions:
278

279
    a) The work must carry prominent notices stating that you modified
280
    it, and giving a relevant date.
281

282
    b) The work must carry prominent notices stating that it is
283
    released under this License and any conditions added under section
284
    7.  This requirement modifies the requirement in section 4 to
285
    "keep intact all notices".
286

287
    c) You must license the entire work, as a whole, under this
288
    License to anyone who comes into possession of a copy.  This
289
    License will therefore apply, along with any applicable section 7
290
    additional terms, to the whole of the work, and all its parts,
291
    regardless of how they are packaged.  This License gives no
292
    permission to license the work in any other way, but it does not
293
    invalidate such permission if you have separately received it.
294

295
    d) If the work has interactive user interfaces, each must display
296
    Appropriate Legal Notices; however, if the Program has interactive
297
    interfaces that do not display Appropriate Legal Notices, your
298
    work need not make them do so.
299

300
  A compilation of a covered work with other separate and independent
301
works, which are not by their nature extensions of the covered work,
302
and which are not combined with it such as to form a larger program,
303
in or on a volume of a storage or distribution medium, is called an
304
"aggregate" if the compilation and its resulting copyright are not
305
used to limit the access or legal rights of the compilation's users
306
beyond what the individual works permit.  Inclusion of a covered work
307
in an aggregate does not cause this License to apply to the other
308
parts of the aggregate.
309

310
  6. Conveying Non-Source Forms.
311

312
  You may convey a covered work in object code form under the terms
313
of sections 4 and 5, provided that you also convey the
314
machine-readable Corresponding Source under the terms of this License,
315
in one of these ways:
316

317
    a) Convey the object code in, or embodied in, a physical product
318
    (including a physical distribution medium), accompanied by the
319
    Corresponding Source fixed on a durable physical medium
320
    customarily used for software interchange.
321

322
    b) Convey the object code in, or embodied in, a physical product
323
    (including a physical distribution medium), accompanied by a
324
    written offer, valid for at least three years and valid for as
325
    long as you offer spare parts or customer support for that product
326
    model, to give anyone who possesses the object code either (1) a
327
    copy of the Corresponding Source for all the software in the
328
    product that is covered by this License, on a durable physical
329
    medium customarily used for software interchange, for a price no
330
    more than your reasonable cost of physically performing this
331
    conveying of source, or (2) access to copy the
332
    Corresponding Source from a network server at no charge.
333

334
    c) Convey individual copies of the object code with a copy of the
335
    written offer to provide the Corresponding Source.  This
336
    alternative is allowed only occasionally and noncommercially, and
337
    only if you received the object code with such an offer, in accord
338
    with subsection 6b.
339

340
    d) Convey the object code by offering access from a designated
341
    place (gratis or for a charge), and offer equivalent access to the
342
    Corresponding Source in the same way through the same place at no
343
    further charge.  You need not require recipients to copy the
344
    Corresponding Source along with the object code.  If the place to
345
    copy the object code is a network server, the Corresponding Source
346
    may be on a different server (operated by you or a third party)
347
    that supports equivalent copying facilities, provided you maintain
348
    clear directions next to the object code saying where to find the
349
    Corresponding Source.  Regardless of what server hosts the
350
    Corresponding Source, you remain obligated to ensure that it is
351
    available for as long as needed to satisfy these requirements.
352

353
    e) Convey the object code using peer-to-peer transmission, provided
354
    you inform other peers where the object code and Corresponding
355
    Source of the work are being offered to the general public at no
356
    charge under subsection 6d.
357

358
  A separable portion of the object code, whose source code is excluded
359
from the Corresponding Source as a System Library, need not be
360
included in conveying the object code work.
361

362
  A "User Product" is either (1) a "consumer product", which means any
363
tangible personal property which is normally used for personal, family,
364
or household purposes, or (2) anything designed or sold for incorporation
365
into a dwelling.  In determining whether a product is a consumer product,
366
doubtful cases shall be resolved in favor of coverage.  For a particular
367
product received by a particular user, "normally used" refers to a
368
typical or common use of that class of product, regardless of the status
369
of the particular user or of the way in which the particular user
370
actually uses, or expects or is expected to use, the product.  A product
371
is a consumer product regardless of whether the product has substantial
372
commercial, industrial or non-consumer uses, unless such uses represent
373
the only significant mode of use of the product.
374

375
  "Installation Information" for a User Product means any methods,
376
procedures, authorization keys, or other information required to install
377
and execute modified versions of a covered work in that User Product from
378
a modified version of its Corresponding Source.  The information must
379
suffice to ensure that the continued functioning of the modified object
380
code is in no case prevented or interfered with solely because
381
modification has been made.
382

383
  If you convey an object code work under this section in, or with, or
384
specifically for use in, a User Product, and the conveying occurs as
385
part of a transaction in which the right of possession and use of the
386
User Product is transferred to the recipient in perpetuity or for a
387
fixed term (regardless of how the transaction is characterized), the
388
Corresponding Source conveyed under this section must be accompanied
389
by the Installation Information.  But this requirement does not apply
390
if neither you nor any third party retains the ability to install
391
modified object code on the User Product (for example, the work has
392
been installed in ROM).
393

394
  The requirement to provide Installation Information does not include a
395
requirement to continue to provide support service, warranty, or updates
396
for a work that has been modified or installed by the recipient, or for
397
the User Product in which it has been modified or installed.  Access to a
398
network may be denied when the modification itself materially and
399
adversely affects the operation of the network or violates the rules and
400
protocols for communication across the network.
401

402
  Corresponding Source conveyed, and Installation Information provided,
403
in accord with this section must be in a format that is publicly
404
documented (and with an implementation available to the public in
405
source code form), and must require no special password or key for
406
unpacking, reading or copying.
407

408
  7. Additional Terms.
409

410
  "Additional permissions" are terms that supplement the terms of this
411
License by making exceptions from one or more of its conditions.
412
Additional permissions that are applicable to the entire Program shall
413
be treated as though they were included in this License, to the extent
414
that they are valid under applicable law.  If additional permissions
415
apply only to part of the Program, that part may be used separately
416
under those permissions, but the entire Program remains governed by
417
this License without regard to the additional permissions.
418

419
  When you convey a copy of a covered work, you may at your option
420
remove any additional permissions from that copy, or from any part of
421
it.  (Additional permissions may be written to require their own
422
removal in certain cases when you modify the work.)  You may place
423
additional permissions on material, added by you to a covered work,
424
for which you have or can give appropriate copyright permission.
425

426
  Notwithstanding any other provision of this License, for material you
427
add to a covered work, you may (if authorized by the copyright holders of
428
that material) supplement the terms of this License with terms:
429

430
    a) Disclaiming warranty or limiting liability differently from the
431
    terms of sections 15 and 16 of this License; or
432

433
    b) Requiring preservation of specified reasonable legal notices or
434
    author attributions in that material or in the Appropriate Legal
435
    Notices displayed by works containing it; or
436

437
    c) Prohibiting misrepresentation of the origin of that material, or
438
    requiring that modified versions of such material be marked in
439
    reasonable ways as different from the original version; or
440

441
    d) Limiting the use for publicity purposes of names of licensors or
442
    authors of the material; or
443

444
    e) Declining to grant rights under trademark law for use of some
445
    trade names, trademarks, or service marks; or
446

447
    f) Requiring indemnification of licensors and authors of that
448
    material by anyone who conveys the material (or modified versions of
449
    it) with contractual assumptions of liability to the recipient, for
450
    any liability that these contractual assumptions directly impose on
451
    those licensors and authors.
452

453
  All other non-permissive additional terms are considered "further
454
restrictions" within the meaning of section 10.  If the Program as you
455
received it, or any part of it, contains a notice stating that it is
456
governed by this License along with a term that is a further
457
restriction, you may remove that term.  If a license document contains
458
a further restriction but permits relicensing or conveying under this
459
License, you may add to a covered work material governed by the terms
460
of that license document, provided that the further restriction does
461
not survive such relicensing or conveying.
462

463
  If you add terms to a covered work in accord with this section, you
464
must place, in the relevant source files, a statement of the
465
additional terms that apply to those files, or a notice indicating
466
where to find the applicable terms.
467

468
  Additional terms, permissive or non-permissive, may be stated in the
469
form of a separately written license, or stated as exceptions;
470
the above requirements apply either way.
471

472
  8. Termination.
473

474
  You may not propagate or modify a covered work except as expressly
475
provided under this License.  Any attempt otherwise to propagate or
476
modify it is void, and will automatically terminate your rights under
477
this License (including any patent licenses granted under the third
478
paragraph of section 11).
479

480
  However, if you cease all violation of this License, then your
481
license from a particular copyright holder is reinstated (a)
482
provisionally, unless and until the copyright holder explicitly and
483
finally terminates your license, and (b) permanently, if the copyright
484
holder fails to notify you of the violation by some reasonable means
485
prior to 60 days after the cessation.
486

487
  Moreover, your license from a particular copyright holder is
488
reinstated permanently if the copyright holder notifies you of the
489
violation by some reasonable means, this is the first time you have
490
received notice of violation of this License (for any work) from that
491
copyright holder, and you cure the violation prior to 30 days after
492
your receipt of the notice.
493

494
  Termination of your rights under this section does not terminate the
495
licenses of parties who have received copies or rights from you under
496
this License.  If your rights have been terminated and not permanently
497
reinstated, you do not qualify to receive new licenses for the same
498
material under section 10.
499

500
  9. Acceptance Not Required for Having Copies.
501

502
  You are not required to accept this License in order to receive or
503
run a copy of the Program.  Ancillary propagation of a covered work
504
occurring solely as a consequence of using peer-to-peer transmission
505
to receive a copy likewise does not require acceptance.  However,
506
nothing other than this License grants you permission to propagate or
507
modify any covered work.  These actions infringe copyright if you do
508
not accept this License.  Therefore, by modifying or propagating a
509
covered work, you indicate your acceptance of this License to do so.
510

511
  10. Automatic Licensing of Downstream Recipients.
512

513
  Each time you convey a covered work, the recipient automatically
514
receives a license from the original licensors, to run, modify and
515
propagate that work, subject to this License.  You are not responsible
516
for enforcing compliance by third parties with this License.
517

518
  An "entity transaction" is a transaction transferring control of an
519
organization, or substantially all assets of one, or subdividing an
520
organization, or merging organizations.  If propagation of a covered
521
work results from an entity transaction, each party to that
522
transaction who receives a copy of the work also receives whatever
523
licenses to the work the party's predecessor in interest had or could
524
give under the previous paragraph, plus a right to possession of the
525
Corresponding Source of the work from the predecessor in interest, if
526
the predecessor has it or can get it with reasonable efforts.
527

528
  You may not impose any further restrictions on the exercise of the
529
rights granted or affirmed under this License.  For example, you may
530
not impose a license fee, royalty, or other charge for exercise of
531
rights granted under this License, and you may not initiate litigation
532
(including a cross-claim or counterclaim in a lawsuit) alleging that
533
any patent claim is infringed by making, using, selling, offering for
534
sale, or importing the Program or any portion of it.
535

536
  11. Patents.
537

538
  A "contributor" is a copyright holder who authorizes use under this
539
License of the Program or a work on which the Program is based.  The
540
work thus licensed is called the contributor's "contributor version".
541

542
  A contributor's "essential patent claims" are all patent claims
543
owned or controlled by the contributor, whether already acquired or
544
hereafter acquired, that would be infringed by some manner, permitted
545
by this License, of making, using, or selling its contributor version,
546
but do not include claims that would be infringed only as a
547
consequence of further modification of the contributor version.  For
548
purposes of this definition, "control" includes the right to grant
549
patent sublicenses in a manner consistent with the requirements of
550
this License.
551

552
  Each contributor grants you a non-exclusive, worldwide, royalty-free
553
patent license under the contributor's essential patent claims, to
554
make, use, sell, offer for sale, import and otherwise run, modify and
555
propagate the contents of its contributor version.
556

557
  In the following three paragraphs, a "patent license" is any express
558
agreement or commitment, however denominated, not to enforce a patent
559
(such as an express permission to practice a patent or covenant not to
560
sue for patent infringement).  To "grant" such a patent license to a
561
party means to make such an agreement or commitment not to enforce a
562
patent against the party.
563

564
  If you convey a covered work, knowingly relying on a patent license,
565
and the Corresponding Source of the work is not available for anyone
566
to copy, free of charge and under the terms of this License, through a
567
publicly available network server or other readily accessible means,
568
then you must either (1) cause the Corresponding Source to be so
569
available, or (2) arrange to deprive yourself of the benefit of the
570
patent license for this particular work, or (3) arrange, in a manner
571
consistent with the requirements of this License, to extend the patent
572
license to downstream recipients.  "Knowingly relying" means you have
573
actual knowledge that, but for the patent license, your conveying the
574
covered work in a country, or your recipient's use of the covered work
575
in a country, would infringe one or more identifiable patents in that
576
country that you have reason to believe are valid.
577

578
  If, pursuant to or in connection with a single transaction or
579
arrangement, you convey, or propagate by procuring conveyance of, a
580
covered work, and grant a patent license to some of the parties
581
receiving the covered work authorizing them to use, propagate, modify
582
or convey a specific copy of the covered work, then the patent license
583
you grant is automatically extended to all recipients of the covered
584
work and works based on it.
585

586
  A patent license is "discriminatory" if it does not include within
587
the scope of its coverage, prohibits the exercise of, or is
588
conditioned on the non-exercise of one or more of the rights that are
589
specifically granted under this License.  You may not convey a covered
590
work if you are a party to an arrangement with a third party that is
591
in the business of distributing software, under which you make payment
592
to the third party based on the extent of your activity of conveying
593
the work, and under which the third party grants, to any of the
594
parties who would receive the covered work from you, a discriminatory
595
patent license (a) in connection with copies of the covered work
596
conveyed by you (or copies made from those copies), or (b) primarily
597
for and in connection with specific products or compilations that
598
contain the covered work, unless you entered into that arrangement,
599
or that patent license was granted, prior to 28 March 2007.
600

601
  Nothing in this License shall be construed as excluding or limiting
602
any implied license or other defenses to infringement that may
603
otherwise be available to you under applicable patent law.
604

605
  12. No Surrender of Others' Freedom.
606

607
  If conditions are imposed on you (whether by court order, agreement or
608
otherwise) that contradict the conditions of this License, they do not
609
excuse you from the conditions of this License.  If you cannot convey a
610
covered work so as to satisfy simultaneously your obligations under this
611
License and any other pertinent obligations, then as a consequence you may
612
not convey it at all.  For example, if you agree to terms that obligate you
613
to collect a royalty for further conveying from those to whom you convey
614
the Program, the only way you could satisfy both those terms and this
615
License would be to refrain entirely from conveying the Program.
616

617
  13. Use with the GNU Affero General Public License.
618

619
  Notwithstanding any other provision of this License, you have
620
permission to link or combine any covered work with a work licensed
621
under version 3 of the GNU Affero General Public License into a single
622
combined work, and to convey the resulting work.  The terms of this
623
License will continue to apply to the part which is the covered work,
624
but the special requirements of the GNU Affero General Public License,
625
section 13, concerning interaction through a network will apply to the
626
combination as such.
627

628
  14. Revised Versions of this License.
629

630
  The Free Software Foundation may publish revised and/or new versions of
631
the GNU General Public License from time to time.  Such new versions will
632
be similar in spirit to the present version, but may differ in detail to
633
address new problems or concerns.
634

635
  Each version is given a distinguishing version number.  If the
636
Program specifies that a certain numbered version of the GNU General
637
Public License "or any later version" applies to it, you have the
638
option of following the terms and conditions either of that numbered
639
version or of any later version published by the Free Software
640
Foundation.  If the Program does not specify a version number of the
641
GNU General Public License, you may choose any version ever published
642
by the Free Software Foundation.
643

644
  If the Program specifies that a proxy can decide which future
645
versions of the GNU General Public License can be used, that proxy's
646
public statement of acceptance of a version permanently authorizes you
647
to choose that version for the Program.
648

649
  Later license versions may give you additional or different
650
permissions.  However, no additional obligations are imposed on any
651
author or copyright holder as a result of your choosing to follow a
652
later version.
653

654
  15. Disclaimer of Warranty.
655

656
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
657
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
658
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
659
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
660
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
661
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
662
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
663
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
664

665
  16. Limitation of Liability.
666

667
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
668
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
669
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
670
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
671
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
672
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
673
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
674
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
675
SUCH DAMAGES.
676

677
  17. Interpretation of Sections 15 and 16.
678

679
  If the disclaimer of warranty and limitation of liability provided
680
above cannot be given local legal effect according to their terms,
681
reviewing courts shall apply local law that most closely approximates
682
an absolute waiver of all civil liability in connection with the
683
Program, unless a warranty or assumption of liability accompanies a
684
copy of the Program in return for a fee.
685

686
                     END OF TERMS AND CONDITIONS
687

688
            How to Apply These Terms to Your New Programs
689

690
  If you develop a new program, and you want it to be of the greatest
691
possible use to the public, the best way to achieve this is to make it
692
free software which everyone can redistribute and change under these terms.
693

694
  To do so, attach the following notices to the program.  It is safest
695
to attach them to the start of each source file to most effectively
696
state the exclusion of warranty; and each file should have at least
697
the "copyright" line and a pointer to where the full notice is found.
698

699
    <one line to give the program's name and a brief idea of what it does.>
700
    Copyright (C) <year>  <name of author>
701

702
    This program is free software: you can redistribute it and/or modify
703
    it under the terms of the GNU General Public License as published by
704
    the Free Software Foundation, either version 3 of the License, or
705
    (at your option) any later version.
706

707
    This program is distributed in the hope that it will be useful,
708
    but WITHOUT ANY WARRANTY; without even the implied warranty of
709
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
710
    GNU General Public License for more details.
711

712
    You should have received a copy of the GNU General Public License
713
    along with this program.  If not, see <http://www.gnu.org/licenses/>.
714

715
Also add information on how to contact you by electronic and paper mail.
716

717
  If the program does terminal interaction, make it output a short
718
notice like this when it starts in an interactive mode:
719

720
    <program>  Copyright (C) <year>  <name of author>
721
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
722
    This is free software, and you are welcome to redistribute it
723
    under certain conditions; type `show c' for details.
724

725
The hypothetical commands `show w' and `show c' should show the appropriate
726
parts of the General Public License.  Of course, your program's commands
727
might be different; for a GUI interface, you would use an "about box".
728

729
  You should also get your employer (if you work as a programmer) or school,
730
if any, to sign a "copyright disclaimer" for the program, if necessary.
731
For more information on this, and how to apply and follow the GNU GPL, see
732
<http://www.gnu.org/licenses/>.
733

734
  The GNU General Public License does not permit incorporating your program
735
into proprietary programs.  If your program is a subroutine library, you
736
may consider it more useful to permit linking proprietary applications with
737
the library.  If this is what you want to do, use the GNU Lesser General
738
Public License instead of this License.  But first, please read
739
<http://www.gnu.org/philosophy/why-not-lgpl.html>.
