 Everyone is permitted to copy and distribute verbatim copies
6
 of this license document, but changing it is not allowed.

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