14 @heading Preamble
15
16 The GNU Affero General Public License is a free, copyleft license
17 for software and other kinds of works, specifically designed to ensure
18 cooperation with the community in the case of network server software.
19
20 The licenses for most software and other practical works are
21 designed to take away your freedom to share and change the works. By
22 contrast, our General Public Licenses are intended to guarantee your
23 freedom to share and change all versions of a program--to make sure it
24 remains free software for all its users.
25
26 When we speak of free software, we are referring to freedom, not
27 price. Our General Public Licenses are designed to make sure that you
28 have the freedom to distribute copies of free software (and charge for
29 them if you wish), that you receive source code or can get it if you
30 want it, that you can change the software or use pieces of it in new
31 free programs, and that you know you can do these things.
32
33 Developers that use our General Public Licenses protect your rights
34 with two steps: (1) assert copyright on the software, and (2) offer
35 you this License which gives you legal permission to copy, distribute
36 and/or modify the software.
37
38 A secondary benefit of defending all users' freedom is that
39 improvements made in alternate versions of the program, if they
40 receive widespread use, become available for other developers to
41 incorporate. Many developers of free software are heartened and
42 encouraged by the resulting cooperation. However, in the case of
43 software used on network servers, this result may fail to come about.
44 The GNU General Public License permits making a modified version and
45 letting the public access it on a server without ever releasing its
46 source code to the public.
47
48 The GNU Affero General Public License is designed specifically to
49 ensure that, in such cases, the modified source code becomes available
50 to the community. It requires the operator of a network server to
51 provide the source code of the modified version running there to the
52 users of that server. Therefore, public use of a modified version, on
53 a publicly accessible server, gives the public access to the source
54 code of the modified version.
55
56 An older license, called the Affero General Public License and
57 published by Affero, was designed to accomplish similar goals. This is
58 a different license, not a version of the Affero GPL, but Affero has
59 released a new version of the Affero GPL which permits relicensing under
60 this license.
61
62 The precise terms and conditions for copying, distribution and
63 modification follow.
64
65 @heading TERMS AND CONDITIONS
66
67 @enumerate 0
68 @item Definitions.
69
70 ``This License'' refers to version 3 of the GNU Affero General Public License.
71
72 ``Copyright'' also means copyright-like laws that apply to other kinds
73 of works, such as semiconductor masks.
74
75 ``The Program'' refers to any copyrightable work licensed under this
76 License. Each licensee is addressed as ``you''. ``Licensees'' and
77 ``recipients'' may be individuals or organizations.
78
79 To ``modify'' a work means to copy from or adapt all or part of the work
80 in a fashion requiring copyright permission, other than the making of
81 an exact copy. The resulting work is called a ``modified version'' of
82 the earlier work or a work ``based on'' the earlier work.
83
84 A ``covered work'' means either the unmodified Program or a work based
85 on the Program.
86
87 To ``propagate'' a work means to do anything with it that, without
88 permission, would make you directly or secondarily liable for
89 infringement under applicable copyright law, except executing it on a
90 computer or modifying a private copy. Propagation includes copying,
91 distribution (with or without modification), making available to the
92 public, and in some countries other activities as well.
93
94 To ``convey'' a work means any kind of propagation that enables other
95 parties to make or receive copies. Mere interaction with a user
96 through a computer network, with no transfer of a copy, is not
97 conveying.
98
99 An interactive user interface displays ``Appropriate Legal Notices'' to
100 the extent that it includes a convenient and prominently visible
101 feature that (1) displays an appropriate copyright notice, and (2)
102 tells the user that there is no warranty for the work (except to the
103 extent that warranties are provided), that licensees may convey the
104 work under this License, and how to view a copy of this License. If
105 the interface presents a list of user commands or options, such as a
106 menu, a prominent item in the list meets this criterion.
107
108 @item Source Code.
109
110 The ``source code'' for a work means the preferred form of the work for
111 making modifications to it. ``Object code'' means any non-source form
112 of a work.
113
114 A ``Standard Interface'' means an interface that either is an official
115 standard defined by a recognized standards body, or, in the case of
116 interfaces specified for a particular programming language, one that
117 is widely used among developers working in that language.
118
119 The ``System Libraries'' of an executable work include anything, other
120 than the work as a whole, that (a) is included in the normal form of
121 packaging a Major Component, but which is not part of that Major
122 Component, and (b) serves only to enable use of the work with that
123 Major Component, or to implement a Standard Interface for which an
124 implementation is available to the public in source code form. A
125 ``Major Component'', in this context, means a major essential component
126 (kernel, window system, and so on) of the specific operating system
127 (if any) on which the executable work runs, or a compiler used to
128 produce the work, or an object code interpreter used to run it.
129
130 The ``Corresponding Source'' for a work in object code form means all
131 the source code needed to generate, install, and (for an executable
132 work) run the object code and to modify the work, including scripts to
133 control those activities. However, it does not include the work's
134 System Libraries, or general-purpose tools or generally available free
135 programs which are used unmodified in performing those activities but
136 which are not part of the work. For example, Corresponding Source
137 includes interface definition files associated with source files for
138 the work, and the source code for shared libraries and dynamically
139 linked subprograms that the work is specifically designed to require,
140 such as by intimate data communication or control flow between those
141 subprograms and other parts of the work.
142
143 The Corresponding Source need not include anything that users can
144 regenerate automatically from other parts of the Corresponding Source.
145
146 The Corresponding Source for a work in source code form is that same
147 work.
148
149 @item Basic Permissions.
150
151 All rights granted under this License are granted for the term of
152 copyright on the Program, and are irrevocable provided the stated
153 conditions are met. This License explicitly affirms your unlimited
154 permission to run the unmodified Program. The output from running a
155 covered work is covered by this License only if the output, given its
156 content, constitutes a covered work. This License acknowledges your
157 rights of fair use or other equivalent, as provided by copyright law.
158
159 You may make, run and propagate covered works that you do not convey,
160 without conditions so long as your license otherwise remains in force.
161 You may convey covered works to others for the sole purpose of having
162 them make modifications exclusively for you, or provide you with
163 facilities for running those works, provided that you comply with the
164 terms of this License in conveying all material for which you do not
165 control copyright. Those thus making or running the covered works for
166 you must do so exclusively on your behalf, under your direction and
167 control, on terms that prohibit them from making any copies of your
168 copyrighted material outside their relationship with you.
169
170 Conveying under any other circumstances is permitted solely under the
171 conditions stated below. Sublicensing is not allowed; section 10
172 makes it unnecessary.
173
174 @item Protecting Users' Legal Rights From Anti-Circumvention Law.
175
176 No covered work shall be deemed part of an effective technological
177 measure under any applicable law fulfilling obligations under article
178 11 of the WIPO copyright treaty adopted on 20 December 1996, or
179 similar laws prohibiting or restricting circumvention of such
180 measures.
181
182 When you convey a covered work, you waive any legal power to forbid
183 circumvention of technological measures to the extent such
184 circumvention is effected by exercising rights under this License with
185 respect to the covered work, and you disclaim any intention to limit
186 operation or modification of the work as a means of enforcing, against
187 the work's users, your or third parties' legal rights to forbid
188 circumvention of technological measures.
189
190 @item Conveying Verbatim Copies.
191
192 You may convey verbatim copies of the Program's source code as you
193 receive it, in any medium, provided that you conspicuously and
194 appropriately publish on each copy an appropriate copyright notice;
195 keep intact all notices stating that this License and any
196 non-permissive terms added in accord with section 7 apply to the code;
197 keep intact all notices of the absence of any warranty; and give all
198 recipients a copy of this License along with the Program.
199
200 You may charge any price or no price for each copy that you convey,
201 and you may offer support or warranty protection for a fee.
202
203 @item Conveying Modified Source Versions.
204
205 You may convey a work based on the Program, or the modifications to
206 produce it from the Program, in the form of source code under the
207 terms of section 4, provided that you also meet all of these
208 conditions:
209
210 @enumerate a
211 @item
212 The work must carry prominent notices stating that you modified it,
213 and giving a relevant date.
214
215 @item
216 The work must carry prominent notices stating that it is released
217 under this License and any conditions added under section 7. This
218 requirement modifies the requirement in section 4 to ``keep intact all
219 notices''.
220
221 @item
222 You must license the entire work, as a whole, under this License to
223 anyone who comes into possession of a copy. This License will
224 therefore apply, along with any applicable section 7 additional terms,
225 to the whole of the work, and all its parts, regardless of how they
226 are packaged. This License gives no permission to license the work in
227 any other way, but it does not invalidate such permission if you have
228 separately received it.
229
230 @item
231 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 work
234 need not make them do so.
235 @end enumerate
236
237 A compilation of a covered work with other separate and independent
238 works, which are not by their nature extensions of the covered work,
239 and which are not combined with it such as to form a larger program,
240 in or on a volume of a storage or distribution medium, is called an
241 ``aggregate'' if the compilation and its resulting copyright are not
242 used to limit the access or legal rights of the compilation's users
243 beyond what the individual works permit. Inclusion of a covered work
244 in an aggregate does not cause this License to apply to the other
245 parts of the aggregate.
246
247 @item Conveying Non-Source Forms.
248
249 You may convey a covered work in object code form under the terms of
250 sections 4 and 5, provided that you also convey the machine-readable
251 Corresponding Source under the terms of this License, in one of these
252 ways:
253
254 @enumerate a
255 @item
256 Convey the object code in, or embodied in, a physical product
257 (including a physical distribution medium), accompanied by the
258 Corresponding Source fixed on a durable physical medium customarily
259 used for software interchange.
260
261 @item
262 Convey the object code in, or embodied in, a physical product
263 (including a physical distribution medium), accompanied by a written
264 offer, valid for at least three years and valid for as long as you
265 offer spare parts or customer support for that product model, to give
266 anyone who possesses the object code either (1) a copy of the
267 Corresponding Source for all the software in the product that is
268 covered by this License, on a durable physical medium customarily used
269 for software interchange, for a price no more than your reasonable
270 cost of physically performing this conveying of source, or (2) access
271 to copy the Corresponding Source from a network server at no charge.
272
273 @item
274 Convey individual copies of the object code with a copy of the written
275 offer to provide the Corresponding Source. This alternative is
276 allowed only occasionally and noncommercially, and only if you
277 received the object code with such an offer, in accord with subsection
278 6b.
279
280 @item
281 Convey the object code by offering access from a designated place
282 (gratis or for a charge), and offer equivalent access to the
283 Corresponding Source in the same way through the same place at no
284 further charge. You need not require recipients to copy the
285 Corresponding Source along with the object code. If the place to copy
286 the object code is a network server, the Corresponding Source may be
287 on a different server (operated by you or a third party) that supports
288 equivalent copying facilities, provided you maintain clear directions
289 next to the object code saying where to find the Corresponding Source.
290 Regardless of what server hosts the Corresponding Source, you remain
291 obligated to ensure that it is available for as long as needed to
292 satisfy these requirements.
293
294 @item
295 Convey the object code using peer-to-peer transmission, provided you
296 inform other peers where the object code and Corresponding Source of
297 the work are being offered to the general public at no charge under
298 subsection 6d.
299
300 @end enumerate
301
302 A separable portion of the object code, whose source code is excluded
303 from the Corresponding Source as a System Library, need not be
304 included in conveying the object code work.
305
306 A ``User Product'' is either (1) a ``consumer product'', which means any
307 tangible personal property which is normally used for personal,
308 family, or household purposes, or (2) anything designed or sold for
309 incorporation into a dwelling. In determining whether a product is a
310 consumer product, doubtful cases shall be resolved in favor of
311 coverage. For a particular product received by a particular user,
312 ``normally used'' refers to a typical or common use of that class of
313 product, regardless of the status of the particular user or of the way
314 in which the particular user actually uses, or expects or is expected
315 to use, the product. A product is a consumer product regardless of
316 whether the product has substantial commercial, industrial or
317 non-consumer uses, unless such uses represent the only significant
318 mode of use of the product.
319
320 ``Installation Information'' for a User Product means any methods,
321 procedures, authorization keys, or other information required to
322 install and execute modified versions of a covered work in that User
323 Product from a modified version of its Corresponding Source. The
324 information must suffice to ensure that the continued functioning of
325 the modified object code is in no case prevented or interfered with
326 solely because modification has been made.
327
328 If you convey an object code work under this section in, or with, or
329 specifically for use in, a User Product, and the conveying occurs as
330 part of a transaction in which the right of possession and use of the
331 User Product is transferred to the recipient in perpetuity or for a
332 fixed term (regardless of how the transaction is characterized), the
333 Corresponding Source conveyed under this section must be accompanied
334 by the Installation Information. But this requirement does not apply
335 if neither you nor any third party retains the ability to install
336 modified object code on the User Product (for example, the work has
337 been installed in ROM).
338
339 The requirement to provide Installation Information does not include a
340 requirement to continue to provide support service, warranty, or
341 updates for a work that has been modified or installed by the
342 recipient, or for the User Product in which it has been modified or
343 installed. Access to a network may be denied when the modification
344 itself materially and adversely affects the operation of the network
345 or violates the rules and protocols for communication across the
346 network.
347
348 Corresponding Source conveyed, and Installation Information provided,
349 in accord with this section must be in a format that is publicly
350 documented (and with an implementation available to the public in
351 source code form), and must require no special password or key for
352 unpacking, reading or copying.
353
354 @item Additional Terms.
355
356 ``Additional permissions'' are terms that supplement the terms of this
357 License by making exceptions from one or more of its conditions.
358 Additional permissions that are applicable to the entire Program shall
359 be treated as though they were included in this License, to the extent
360 that they are valid under applicable law. If additional permissions
361 apply only to part of the Program, that part may be used separately
362 under those permissions, but the entire Program remains governed by
363 this License without regard to the additional permissions.
364
365 When you convey a copy of a covered work, you may at your option
366 remove any additional permissions from that copy, or from any part of
367 it. (Additional permissions may be written to require their own
368 removal in certain cases when you modify the work.) You may place
369 additional permissions on material, added by you to a covered work,
370 for which you have or can give appropriate copyright permission.
371
372 Notwithstanding any other provision of this License, for material you
373 add to a covered work, you may (if authorized by the copyright holders
374 of that material) supplement the terms of this License with terms:
375
376 @enumerate a
377 @item
378 Disclaiming warranty or limiting liability differently from the terms
379 of sections 15 and 16 of this License; or
380
381 @item
382 Requiring preservation of specified reasonable legal notices or author
383 attributions in that material or in the Appropriate Legal Notices
384 displayed by works containing it; or
385
386 @item
387 Prohibiting misrepresentation of the origin of that material, or
388 requiring that modified versions of such material be marked in
389 reasonable ways as different from the original version; or
390
391 @item
392 Limiting the use for publicity purposes of names of licensors or
393 authors of the material; or
394
395 @item
396 Declining to grant rights under trademark law for use of some trade
397 names, trademarks, or service marks; or
398
399 @item
400 Requiring indemnification of licensors and authors of that material by
401 anyone who conveys the material (or modified versions of it) with
402 contractual assumptions of liability to the recipient, for any
403 liability that these contractual assumptions directly impose on those
404 licensors and authors.
405 @end enumerate
406
407 All other non-permissive additional terms are considered ``further
408 restrictions'' within the meaning of section 10. If the Program as you
409 received it, or any part of it, contains a notice stating that it is
410 governed by this License along with a term that is a further
411 restriction, you may remove that term. If a license document contains
412 a further restriction but permits relicensing or conveying under this
413 License, you may add to a covered work material governed by the terms
414 of that license document, provided that the further restriction does
415 not survive such relicensing or conveying.
416
417 If you add terms to a covered work in accord with this section, you
418 must place, in the relevant source files, a statement of the
419 additional terms that apply to those files, or a notice indicating
420 where to find the applicable terms.
421
422 Additional terms, permissive or non-permissive, may be stated in the
423 form of a separately written license, or stated as exceptions; the
424 above requirements apply either way.
425
426 @item Termination.
427
428 You may not propagate or modify a covered work except as expressly
429 provided under this License. Any attempt otherwise to propagate or
430 modify it is void, and will automatically terminate your rights under
431 this License (including any patent licenses granted under the third
432 paragraph of section 11).
433
434 However, if you cease all violation of this License, then your license
435 from a particular copyright holder is reinstated (a) provisionally,
436 unless and until the copyright holder explicitly and finally
437 terminates your license, and (b) permanently, if the copyright holder
438 fails to notify you of the violation by some reasonable means prior to
439 60 days after the cessation.
440
441 Moreover, your license from a particular copyright holder is
442 reinstated permanently if the copyright holder notifies you of the
443 violation by some reasonable means, this is the first time you have
444 received notice of violation of this License (for any work) from that
445 copyright holder, and you cure the violation prior to 30 days after
446 your receipt of the notice.
447
448 Termination of your rights under this section does not terminate the
449 licenses of parties who have received copies or rights from you under
450 this License. If your rights have been terminated and not permanently
451 reinstated, you do not qualify to receive new licenses for the same
452 material under section 10.
453
454 @item Acceptance Not Required for Having Copies.
455
456 You are not required to accept this License in order to receive or run
457 a copy of the Program. Ancillary propagation of a covered work
458 occurring solely as a consequence of using peer-to-peer transmission
459 to receive a copy likewise does not require acceptance. However,
460 nothing other than this License grants you permission to propagate or
461 modify any covered work. These actions infringe copyright if you do
462 not accept this License. Therefore, by modifying or propagating a
463 covered work, you indicate your acceptance of this License to do so.
464
465 @item Automatic Licensing of Downstream Recipients.
466
467 Each time you convey a covered work, the recipient automatically
468 receives a license from the original licensors, to run, modify and
469 propagate that work, subject to this License. You are not responsible
470 for enforcing compliance by third parties with this License.
471
472 An ``entity transaction'' is a transaction transferring control of an
473 organization, or substantially all assets of one, or subdividing an
474 organization, or merging organizations. If propagation of a covered
475 work results from an entity transaction, each party to that
476 transaction who receives a copy of the work also receives whatever
477 licenses to the work the party's predecessor in interest had or could
478 give under the previous paragraph, plus a right to possession of the
479 Corresponding Source of the work from the predecessor in interest, if
480 the predecessor has it or can get it with reasonable efforts.
481
482 You may not impose any further restrictions on the exercise of the
483 rights granted or affirmed under this License. For example, you may
484 not impose a license fee, royalty, or other charge for exercise of
485 rights granted under this License, and you may not initiate litigation
486 (including a cross-claim or counterclaim in a lawsuit) alleging that
487 any patent claim is infringed by making, using, selling, offering for
488 sale, or importing the Program or any portion of it.
489
490 @item Patents.
491
492 A ``contributor'' is a copyright holder who authorizes use under this
493 License of the Program or a work on which the Program is based. The
494 work thus licensed is called the contributor's ``contributor version''.
495
496 A contributor's ``essential patent claims'' are all patent claims owned
497 or controlled by the contributor, whether already acquired or
498 hereafter acquired, that would be infringed by some manner, permitted
499 by this License, of making, using, or selling its contributor version,
500 but do not include claims that would be infringed only as a
501 consequence of further modification of the contributor version. For
502 purposes of this definition, ``control'' includes the right to grant
503 patent sublicenses in a manner consistent with the requirements of
504 this License.
505
506 Each contributor grants you a non-exclusive, worldwide, royalty-free
507 patent license under the contributor's essential patent claims, to
508 make, use, sell, offer for sale, import and otherwise run, modify and
509 propagate the contents of its contributor version.
510
511 In the following three paragraphs, a ``patent license'' is any express
512 agreement or commitment, however denominated, not to enforce a patent
513 (such as an express permission to practice a patent or covenant not to
514 sue for patent infringement). To ``grant'' such a patent license to a
515 party means to make such an agreement or commitment not to enforce a
516 patent against the party.
517
518 If you convey a covered work, knowingly relying on a patent license,
519 and the Corresponding Source of the work is not available for anyone
520 to copy, free of charge and under the terms of this License, through a
521 publicly available network server or other readily accessible means,
522 then you must either (1) cause the Corresponding Source to be so
523 available, or (2) arrange to deprive yourself of the benefit of the
524 patent license for this particular work, or (3) arrange, in a manner
525 consistent with the requirements of this License, to extend the patent
526 license to downstream recipients. ``Knowingly relying'' means you have
527 actual knowledge that, but for the patent license, your conveying the
528 covered work in a country, or your recipient's use of the covered work
529 in a country, would infringe one or more identifiable patents in that
530 country that you have reason to believe are valid.
531
532 If, pursuant to or in connection with a single transaction or
533 arrangement, you convey, or propagate by procuring conveyance of, a
534 covered work, and grant a patent license to some of the parties
535 receiving the covered work authorizing them to use, propagate, modify
536 or convey a specific copy of the covered work, then the patent license
537 you grant is automatically extended to all recipients of the covered
538 work and works based on it.

540 A patent license is ``discriminatory'' if it does not include within the
541 scope of its coverage, prohibits the exercise of, or is conditioned on
542 the non-exercise of one or more of the rights that are specifically
543 granted under this License. You may not convey a covered work if you
544 are a party to an arrangement with a third party that is in the
545 business of distributing software, under which you make payment to the
546 third party based on the extent of your activity of conveying the
547 work, and under which the third party grants, to any of the parties
548 who would receive the covered work from you, a discriminatory patent
549 license (a) in connection with copies of the covered work conveyed by
550 you (or copies made from those copies), or (b) primarily for and in
551 connection with specific products or compilations that contain the
552 covered work, unless you entered into that arrangement, or that patent
553 license was granted, prior to 28 March 2007.
554
555 Nothing in this License shall be construed as excluding or limiting
556 any implied license or other defenses to infringement that may
557 otherwise be available to you under applicable patent law.

559 @item No Surrender of Others' Freedom.
560
561 If conditions are imposed on you (whether by court order, agreement or
562 otherwise) that contradict the conditions of this License, they do not
563 excuse you from the conditions of this License. If you cannot convey
564 a covered work so as to satisfy simultaneously your obligations under
565 this License and any other pertinent obligations, then as a
566 consequence you may not convey it at all. For example, if you agree
567 to terms that obligate you to collect a royalty for further conveying
568 from those to whom you convey the Program, the only way you could
569 satisfy both those terms and this License would be to refrain entirely
570 from conveying the Program.
571
572 @item Remote Network Interaction; Use with the GNU General Public License.
573
574 Notwithstanding any other provision of this License, if you modify the
575 Program, your modified version must prominently offer all users interacting
576 with it remotely through a computer network (if your version supports such
577 interaction) an opportunity to receive the Corresponding Source of your
578 version by providing access to the Corresponding Source from a network
579 server at no charge, through some standard or customary means of
580 facilitating copying of software. This Corresponding Source shall include
581 the Corresponding Source for any work covered by version 3 of the GNU
582 General Public License that is incorporated pursuant to the following
583 paragraph.
584
585 Notwithstanding any other provision of this License, you have permission to
586 link or combine any covered work with a work licensed under version 3 of
587 the GNU General Public License into a single combined work, and to convey
588 the resulting work. The terms of this License will continue to apply to
589 the part which is the covered work, but the work with which it is combined
590 will remain governed by version 3 of the GNU General Public License.
591
592 @item Revised Versions of this License.
593
594 The Free Software Foundation may publish revised and/or new versions
595 of the GNU Affero General Public License from time to time. Such new
596 versions will be similar in spirit to the present version, but may
597 differ in detail to address new problems or concerns.
598
599 Each version is given a distinguishing version number. If the Program
600 specifies that a certain numbered version of the GNU Affero General Public
601 License ``or any later version'' applies to it, you have the option of
602 following the terms and conditions either of that numbered version or
603 of any later version published by the Free Software Foundation. If
604 the Program does not specify a version number of the GNU Affero General
605 Public License, you may choose any version ever published by the Free
606 Software Foundation.
607
608 If the Program specifies that a proxy can decide which future versions
609 of the GNU Affero General Public License can be used, that proxy's public
610 statement of acceptance of a version permanently authorizes you to
611 choose that version for the Program.
612
613 Later license versions may give you additional or different
614 permissions. However, no additional obligations are imposed on any
615 author or copyright holder as a result of your choosing to follow a
616 later version.
617
618 @item Disclaimer of Warranty.
619
620 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
621 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
622 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT
623 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
624 LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
625 A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
626 PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
627 DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
628 CORRECTION.
629
630 @item Limitation of Liability.
631
632 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
633 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
634 CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
635 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
636 ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
637 NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
638 LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
639 TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
640 PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
641
642 @item Interpretation of Sections 15 and 16.
643
644 If the disclaimer of warranty and limitation of liability provided
645 above cannot be given local legal effect according to their terms,
646 reviewing courts shall apply local law that most closely approximates
647 an absolute waiver of all civil liability in connection with the
648 Program, unless a warranty or assumption of liability accompanies a
649 copy of the Program in return for a fee.

655 @heading How to Apply These Terms to Your New Programs
656
657 If you develop a new program, and you want it to be of the greatest
658 possible use to the public, the best way to achieve this is to make it
659 free software which everyone can redistribute and change under these
660 terms.
661
662 To do so, attach the following notices to the program. It is safest
663 to attach them to the start of each source file to most effectively
664 state the exclusion of warranty; and each file should have at least
665 the ``copyright'' line and a pointer to where the full notice is found.

671 This program is free software: you can redistribute it and/or modify
672 it under the terms of the GNU Affero General Public License as published by
673 the Free Software Foundation, either version 3 of the License, or (at
674 your option) any later version.
675
676 This program is distributed in the hope that it will be useful, but
677 WITHOUT ANY WARRANTY; without even the implied warranty of
678 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
679 Affero General Public License for more details.
680
681 You should have received a copy of the GNU Affero General Public License
682 along with this program. If not, see @url{http://www.gnu.org/licenses/}.
683 @end smallexample
684
685 Also add information on how to contact you by electronic and paper mail.
686
687 If your software can interact with users remotely through a computer
688 network, you should also make sure that it provides a way for users to
689 get its source. For example, if your program is a web application, its
690 interface could display a ``Source'' link that leads users to an archive
691 of the code. There are many ways you could offer source, and different
692 solutions will be better for different programs; see section 13 for the
693 specific requirements.
694
695 You should also get your employer (if you work as a programmer) or school,
696 if any, to sign a ``copyright disclaimer'' for the program, if necessary.
