7Everyone is permitted to copy and distribute verbatim copies of this license
8document, but changing it is not allowed.

10Preamble
11
12The GNU Affero General Public License is a free, copyleft license for software
13and other kinds of works, specifically designed to ensure cooperation with
14the community in the case of network server software.
15
16The licenses for most software and other practical works are designed to take
17away your freedom to share and change the works. By contrast, our General
18Public Licenses are intended to guarantee your freedom to share and change
19all versions of a program--to make sure it remains free software for all its
20users.
21
22When we speak of free software, we are referring to freedom, not price. Our
23General Public Licenses are designed to make sure that you have the freedom
24to distribute copies of free software (and charge for them if you wish), that
25you receive source code or can get it if you want it, that you can change
26the software or use pieces of it in new free programs, and that you know you
27can do these things.
28
29Developers that use our General Public Licenses protect your rights with two
30steps: (1) assert copyright on the software, and (2) offer you this License
31which gives you legal permission to copy, distribute and/or modify the software.
32
33A secondary benefit of defending all users' freedom is that improvements made
34in alternate versions of the program, if they receive widespread use, become
35available for other developers to incorporate. Many developers of free software
36are heartened and encouraged by the resulting cooperation. However, in the
37case of software used on network servers, this result may fail to come about.
38The GNU General Public License permits making a modified version and letting
39the public access it on a server without ever releasing its source code to
40the public.
41
42The GNU Affero General Public License is designed specifically to ensure that,
43in such cases, the modified source code becomes available to the community.
44It requires the operator of a network server to provide the source code of
45the modified version running there to the users of that server. Therefore,
46public use of a modified version, on a publicly accessible server, gives the
47public access to the source code of the modified version.
48
49An older license, called the Affero General Public License and published by
50Affero, was designed to accomplish similar goals. This is a different license,
51not a version of the Affero GPL, but Affero has released a new version of
52the Affero GPL which permits relicensing under this license.
53
54The precise terms and conditions for copying, distribution and modification
55follow.
56
57TERMS AND CONDITIONS
58
59 0. Definitions.
60
61 "This License" refers to version 3 of the GNU Affero General Public License.
62
63"Copyright" also means copyright-like laws that apply to other kinds of works,
64such as semiconductor masks.
65
66"The Program" refers to any copyrightable work licensed under this License.
67Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals
68or organizations.
69
70To "modify" a work means to copy from or adapt all or part of the work in
71a fashion requiring copyright permission, other than the making of an exact
72copy. The resulting work is called a "modified version" of the earlier work
73or a work "based on" the earlier work.
74
75A "covered work" means either the unmodified Program or a work based on the
76Program.
77
78To "propagate" a work means to do anything with it that, without permission,
79would make you directly or secondarily liable for infringement under applicable
80copyright law, except executing it on a computer or modifying a private copy.
81Propagation includes copying, distribution (with or without modification),
82making available to the public, and in some countries other activities as
83well.
84
85To "convey" a work means any kind of propagation that enables other parties
86to make or receive copies. Mere interaction with a user through a computer
87network, with no transfer of a copy, is not conveying.
88
89An interactive user interface displays "Appropriate Legal Notices" to the
90extent that it includes a convenient and prominently visible feature that
91(1) displays an appropriate copyright notice, and (2) tells the user that
92there is no warranty for the work (except to the extent that warranties are
93provided), that licensees may convey the work under this License, and how
94to view a copy of this License. If the interface presents a list of user commands
95or options, such as a menu, a prominent item in the list meets this criterion.
96
97 1. Source Code.
98
99The "source code" for a work means the preferred form of the work for making
100modifications to it. "Object code" means any non-source form of a work.
101
102A "Standard Interface" means an interface that either is an official standard
103defined by a recognized standards body, or, in the case of interfaces specified
104for a particular programming language, one that is widely used among developers
105working in that language.
106
107The "System Libraries" of an executable work include anything, other than
108the work as a whole, that (a) is included in the normal form of packaging
109a Major Component, but which is not part of that Major Component, and (b)
110serves only to enable use of the work with that Major Component, or to implement
111a Standard Interface for which an implementation is available to the public
112in source code form. A "Major Component", in this context, means a major essential
113component (kernel, window system, and so on) of the specific operating system
114(if any) on which the executable work runs, or a compiler used to produce
115the work, or an object code interpreter used to run it.
116
117The "Corresponding Source" for a work in object code form means all the source
118code needed to generate, install, and (for an executable work) run the object
119code and to modify the work, including scripts to control those activities.
120However, it does not include the work's System Libraries, or general-purpose
121tools or generally available free programs which are used unmodified in performing
122those activities but which are not part of the work. For example, Corresponding
123Source includes interface definition files associated with source files for
124the work, and the source code for shared libraries and dynamically linked
125subprograms that the work is specifically designed to require, such as by
126intimate data communication or control flow between those
127
128 subprograms and other parts of the work.
129
130The Corresponding Source need not include anything that users can regenerate
131automatically from other parts of the Corresponding Source.
132
133 The Corresponding Source for a work in source code form is that same work.
134
135 2. Basic Permissions.
136
137All rights granted under this License are granted for the term of copyright
138on the Program, and are irrevocable provided the stated conditions are met.
139This License explicitly affirms your unlimited permission to run the unmodified
140Program. The output from running a covered work is covered by this License
141only if the output, given its content, constitutes a covered work. This License
142acknowledges your rights of fair use or other equivalent, as provided by copyright
143law.
144
145You may make, run and propagate covered works that you do not convey, without
146conditions so long as your license otherwise remains in force. You may convey
147covered works to others for the sole purpose of having them make modifications
148exclusively for you, or provide you with facilities for running those works,
149provided that you comply with the terms of this License in conveying all material
150for which you do not control copyright. Those thus making or running the covered
151works for you must do so exclusively on your behalf, under your direction
152and control, on terms that prohibit them from making any copies of your copyrighted
153material outside their relationship with you.
154
155Conveying under any other circumstances is permitted solely under the conditions
156stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
157
158 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
159
160No covered work shall be deemed part of an effective technological measure
161under any applicable law fulfilling obligations under article 11 of the WIPO
162copyright treaty adopted on 20 December 1996, or similar laws prohibiting
163or restricting circumvention of such measures.
164
165When you convey a covered work, you waive any legal power to forbid circumvention
166of technological measures to the extent such circumvention is effected by
167exercising rights under this License with respect to the covered work, and
168you disclaim any intention to limit operation or modification of the work
169as a means of enforcing, against the work's users, your or third parties'
170legal rights to forbid circumvention of technological measures.
171
172 4. Conveying Verbatim Copies.
173
174You may convey verbatim copies of the Program's source code as you receive
175it, in any medium, provided that you conspicuously and appropriately publish
176on each copy an appropriate copyright notice; keep intact all notices stating
177that this License and any non-permissive terms added in accord with section
1787 apply to the code; keep intact all notices of the absence of any warranty;
179and give all recipients a copy of this License along with the Program.
180
181You may charge any price or no price for each copy that you convey, and you
182may offer support or warranty protection for a fee.
183
184 5. Conveying Modified Source Versions.
185
186You may convey a work based on the Program, or the modifications to produce
187it from the Program, in the form of source code under the terms of section
1884, provided that you also meet all of these conditions:
189
190a) The work must carry prominent notices stating that you modified it, and
191giving a relevant date.
192
193b) The work must carry prominent notices stating that it is released under
194this License and any conditions added under section 7. This requirement modifies
195the requirement in section 4 to "keep intact all notices".
196
197c) You must license the entire work, as a whole, under this License to anyone
198who comes into possession of a copy. This License will therefore apply, along
199with any applicable section 7 additional terms, to the whole of the work,
200and all its parts, regardless of how they are packaged. This License gives
201no permission to license the work in any other way, but it does not invalidate
202such permission if you have separately received it.
203
204d) If the work has interactive user interfaces, each must display Appropriate
205Legal Notices; however, if the Program has interactive interfaces that do
206not display Appropriate Legal Notices, your work need not make them do so.
207
208A compilation of a covered work with other separate and independent works,
209which are not by their nature extensions of the covered work, and which are
210not combined with it such as to form a larger program, in or on a volume of
211a storage or distribution medium, is called an "aggregate" if the compilation
212and its resulting copyright are not used to limit the access or legal rights
213of the compilation's users beyond what the individual works permit. Inclusion
214of a covered work in an aggregate does not cause this License to apply to
215the other parts of the aggregate.
216
217 6. Conveying Non-Source Forms.
218
219You may convey a covered work in object code form under the terms of sections
2204 and 5, provided that you also convey the machine-readable Corresponding
221Source under the terms of this License, in one of these ways:
222
223a) Convey the object code in, or embodied in, a physical product (including
224a physical distribution medium), accompanied by the Corresponding Source fixed
225on a durable physical medium customarily used for software interchange.
226
227b) Convey the object code in, or embodied in, a physical product (including
228a physical distribution medium), accompanied by a written offer, valid for
229at least three years and valid for as long as you offer spare parts or customer
230support for that product model, to give anyone who possesses the object code
231either (1) a copy of the Corresponding Source for all the software in the
232product that is covered by this License, on a durable physical medium customarily
233used for software interchange, for a price no more than your reasonable cost
234of physically performing this conveying of source, or (2) access to copy the
235Corresponding Source from a network server at no charge.
236
237c) Convey individual copies of the object code with a copy of the written
238offer to provide the Corresponding Source. This alternative is allowed only
239occasionally and noncommercially, and only if you received the object code
240with such an offer, in accord with subsection 6b.
241
242d) Convey the object code by offering access from a designated place (gratis
243or for a charge), and offer equivalent access to the Corresponding Source
244in the same way through the same place at no further charge. You need not
245require recipients to copy the Corresponding Source along with the object
246code. If the place to copy the object code is a network server, the Corresponding
247Source may be on a different server (operated by you or a third party) that
248supports equivalent copying facilities, provided you maintain clear directions
249next to the object code saying where to find the Corresponding Source. Regardless
250of what server hosts the Corresponding Source, you remain obligated to ensure
251that it is available for as long as needed to satisfy these requirements.
252
253e) Convey the object code using peer-to-peer transmission, provided you inform
254other peers where the object code and Corresponding Source of the work are
255being offered to the general public at no charge under subsection 6d.
256
257A separable portion of the object code, whose source code is excluded from
258the Corresponding Source as a System Library, need not be included in conveying
259the object code work.
260
261A "User Product" is either (1) a "consumer product", which means any tangible
262personal property which is normally used for personal, family, or household
263purposes, or (2) anything designed or sold for incorporation into a dwelling.
264In determining whether a product is a consumer product, doubtful cases shall
265be resolved in favor of coverage. For a particular product received by a particular
266user, "normally used" refers to a typical or common use of that class of product,
267regardless of the status of the particular user or of the way in which the
268particular user actually uses, or expects or is expected to use, the product.
269A product is a consumer product regardless of whether the product has substantial
270commercial, industrial or non-consumer uses, unless such uses represent the
271only significant mode of use of the product.
272
273"Installation Information" for a User Product means any methods, procedures,
274authorization keys, or other information required to install and execute modified
275versions of a covered work in that User Product from a modified version of
276its Corresponding Source. The information must suffice to ensure that the
277continued functioning of the modified object code is in no case prevented
278or interfered with solely because modification has been made.
279
280If you convey an object code work under this section in, or with, or specifically
281for use in, a User Product, and the conveying occurs as part of a transaction
282in which the right of possession and use of the User Product is transferred
283to the recipient in perpetuity or for a fixed term (regardless of how the
284transaction is characterized), the Corresponding Source conveyed under this
285section must be accompanied by the Installation Information. But this requirement
286does not apply if neither you nor any third party retains the ability to install
287modified object code on the User Product (for example, the work has been installed
288in ROM).
289
290The requirement to provide Installation Information does not include a requirement
291to continue to provide support service, warranty, or updates for a work that
292has been modified or installed by the recipient, or for the User Product in
293which it has been modified or installed. Access to a network may be denied
294when the modification itself materially and adversely affects the operation
295of the network or violates the rules and protocols for communication across
296the network.
297
298Corresponding Source conveyed, and Installation Information provided, in accord
299with this section must be in a format that is publicly documented (and with
300an implementation available to the public in source code form), and must require
301no special password or key for unpacking, reading or copying.
302
303 7. Additional Terms.
304
305"Additional permissions" are terms that supplement the terms of this License
306by making exceptions from one or more of its conditions. Additional permissions
307that are applicable to the entire Program shall be treated as though they
308were included in this License, to the extent that they are valid under applicable
309law. If additional permissions apply only to part of the Program, that part
310may be used separately under those permissions, but the entire Program remains
311governed by this License without regard to the additional permissions.
312
313When you convey a copy of a covered work, you may at your option remove any
314additional permissions from that copy, or from any part of it. (Additional
315permissions may be written to require their own removal in certain cases when
316you modify the work.) You may place additional permissions on material, added
317by you to a covered work, for which you have or can give appropriate copyright
318permission.
319
320Notwithstanding any other provision of this License, for material you add
321to a covered work, you may (if authorized by the copyright holders of that
322material) supplement the terms of this License with terms:
323
324a) Disclaiming warranty or limiting liability differently from the terms of
325sections 15 and 16 of this License; or
326
327b) Requiring preservation of specified reasonable legal notices or author
328attributions in that material or in the Appropriate Legal Notices displayed
329by works containing it; or
330
331c) Prohibiting misrepresentation of the origin of that material, or requiring
332that modified versions of such material be marked in reasonable ways as different
333from the original version; or
334
335d) Limiting the use for publicity purposes of names of licensors or authors
336of the material; or
337
338e) Declining to grant rights under trademark law for use of some trade names,
339trademarks, or service marks; or
340
341f) Requiring indemnification of licensors and authors of that material by
342anyone who conveys the material (or modified versions of it) with contractual
343assumptions of liability to the recipient, for any liability that these contractual
344assumptions directly impose on those licensors and authors.
345
346All other non-permissive additional terms are considered "further restrictions"
347within the meaning of section 10. If the Program as you received it, or any
348part of it, contains a notice stating that it is governed by this License
349along with a term that is a further restriction, you may remove that term.
350If a license document contains a further restriction but permits relicensing
351or conveying under this License, you may add to a covered work material governed
352by the terms of that license document, provided that the further restriction
353does not survive such relicensing or conveying.
354
355If you add terms to a covered work in accord with this section, you must place,
356in the relevant source files, a statement of the additional terms that apply
357to those files, or a notice indicating where to find the applicable terms.
358
359Additional terms, permissive or non-permissive, may be stated in the form
360of a separately written license, or stated as exceptions; the above requirements
361apply either way.
362
363 8. Termination.
364
365You may not propagate or modify a covered work except as expressly provided
366under this License. Any attempt otherwise to propagate or modify it is void,
367and will automatically terminate your rights under this License (including
368any patent licenses granted under the third paragraph of section 11).
369
370However, if you cease all violation of this License, then your license from
371a particular copyright holder is reinstated (a) provisionally, unless and
372until the copyright holder explicitly and finally terminates your license,
373and (b) permanently, if the copyright holder fails to notify you of the violation
374by some reasonable means prior to 60 days after the cessation.
375
376Moreover, your license from a particular copyright holder is reinstated permanently
377if the copyright holder notifies you of the violation by some reasonable means,
378this is the first time you have received notice of violation of this License
379(for any work) from that copyright holder, and you cure the violation prior
380to 30 days after your receipt of the notice.
381
382Termination of your rights under this section does not terminate the licenses
383of parties who have received copies or rights from you under this License.
384If your rights have been terminated and not permanently reinstated, you do
385not qualify to receive new licenses for the same material under section 10.
386
387 9. Acceptance Not Required for Having Copies.
388
389You are not required to accept this License in order to receive or run a copy
390of the Program. Ancillary propagation of a covered work occurring solely as
391a consequence of using peer-to-peer transmission to receive a copy likewise
392does not require acceptance. However, nothing other than this License grants
393you permission to propagate or modify any covered work. These actions infringe
394copyright if you do not accept this License. Therefore, by modifying or propagating
395a covered work, you indicate your acceptance of this License to do so.
396
397 10. Automatic Licensing of Downstream Recipients.
398
399Each time you convey a covered work, the recipient automatically receives
400a license from the original licensors, to run, modify and propagate that work,
401subject to this License. You are not responsible for enforcing compliance
402by third parties with this License.
403
404An "entity transaction" is a transaction transferring control of an organization,
405or substantially all assets of one, or subdividing an organization, or merging
406organizations. If propagation of a covered work results from an entity transaction,
407each party to that transaction who receives a copy of the work also receives
408whatever licenses to the work the party's predecessor in interest had or could
409give under the previous paragraph, plus a right to possession of the Corresponding
410Source of the work from the predecessor in interest, if the predecessor has
411it or can get it with reasonable efforts.
412
413You may not impose any further restrictions on the exercise of the rights
414granted or affirmed under this License. For example, you may not impose a
415license fee, royalty, or other charge for exercise of rights granted under
416this License, and you may not initiate litigation (including a cross-claim
417or counterclaim in a lawsuit) alleging that any patent claim is infringed
418by making, using, selling, offering for sale, or importing the Program or
419any portion of it.
420
421 11. Patents.
422
423A "contributor" is a copyright holder who authorizes use under this License
424of the Program or a work on which the Program is based. The work thus licensed
425is called the contributor's "contributor version".
426
427A contributor's "essential patent claims" are all patent claims owned or controlled
428by the contributor, whether already acquired or hereafter acquired, that would
429be infringed by some manner, permitted by this License, of making, using,
430or selling its contributor version, but do not include claims that would be
431infringed only as a consequence of further modification of the contributor
432version. For purposes of this definition, "control" includes the right to
433grant patent sublicenses in a manner consistent with the requirements of this
434License.
435
436Each contributor grants you a non-exclusive, worldwide, royalty-free patent
437license under the contributor's essential patent claims, to make, use, sell,
438offer for sale, import and otherwise run, modify and propagate the contents
439of its contributor version.
440
441In the following three paragraphs, a "patent license" is any express agreement
442or commitment, however denominated, not to enforce a patent (such as an express
443permission to practice a patent or covenant not to s ue for patent infringement).
444To "grant" such a patent license to a party means to make such an agreement
445or commitment not to enforce a patent against the party.
446
447If you convey a covered work, knowingly relying on a patent license, and the
448Corresponding Source of the work is not available for anyone to copy, free
449of charge and under the terms of this License, through a publicly available
450network server or other readily accessible means, then you must either (1)
451cause the Corresponding Source to be so available, or (2) arrange to deprive
452yourself of the benefit of the patent license for this particular work, or
453(3) arrange, in a manner consistent with the requirements of this License,
454to extend the patent
455
456license to downstream recipients. "Knowingly relying" means you have actual
457knowledge that, but for the patent license, your conveying the covered work
458in a country, or your recipient's use of the covered work in a country, would
459infringe one or more identifiable patents in that country that you have reason
460to believe are valid.
461
462If, pursuant to or in connection with a single transaction or arrangement,
463you convey, or propagate by procuring conveyance of, a covered work, and grant
464a patent license to some of the parties receiving the covered work authorizing
465them to use, propagate, modify or convey a specific copy of the covered work,
466then the patent license you grant is automatically extended to all recipients
467of the covered work and works based on it.
468
469A patent license is "discriminatory" if it does not include within the scope
470of its coverage, prohibits the exercise of, or is conditioned on the non-exercise
471of one or more of the rights that are specifically granted under this License.
472You may not convey a covered work if you are a party to an arrangement with
473a third party that is in the business of distributing software, under which
474you make payment to the third party based on the extent of your activity of
475conveying the work, and under which the third party grants, to any of the
476parties who would receive the covered work from you, a discriminatory patent
477license (a) in connection with copies of the covered work conveyed by you
478(or copies made from those copies), or (b) primarily for and in connection
479with specific products or compilations that contain the covered work, unless
480you entered into that arrangement, or that patent license was granted, prior
481to 28 March 2007.
482
483Nothing in this License shall be construed as excluding or limiting any implied
484license or other defenses to infringement that may otherwise be available
485to you under applicable patent law.
486
487 12. No Surrender of Others' Freedom.
488
489If conditions are imposed on you (whether by court order, agreement or otherwise)
490that contradict the conditions of this License, they do not excuse you from
491the conditions of this License. If you cannot convey a covered work so as
492to satisfy simultaneously your obligations under this License and any other
493pertinent obligations, then as a consequence you may
494
495not convey it at all. For example, if you agree to terms that obligate you
496to collect a royalty for further conveying from those to whom you convey the
497Program, the only way you could satisfy both those terms and this License
498would be to refrain entirely from conveying the Program.
499
500 13. Remote Network Interaction; Use with the GNU General Public License.
501
502Notwithstanding any other provision of this License, if you modify the Program,
503your modified version must prominently offer all users interacting with it
504remotely through a computer network (if your version supports such interaction)
505an opportunity to receive the Corresponding Source of your version by providing
506access to the Corresponding Source from a network server at no charge, through
507some standard or customary means of facilitating copying of software. This
508Corresponding Source shall include the Corresponding Source for any work covered
509by version 3 of the GNU General Public License that is incorporated pursuant
510to the following paragraph.
511
512Notwithstanding any other provision of this License, you have permission to
513link or combine any covered work with a work licensed under version 3 of the
514GNU General Public License into a single combined work, and to convey the
515resulting work. The terms of this License will continue to apply to the part
516which is the covered work, but the work with which it is combined will remain
517governed by version 3 of the GNU General Public License.
518
519 14. Revised Versions of this License.
520
521The Free Software Foundation may publish revised and/or new versions of the
522GNU Affero General Public License from time to time. Such new versions will
523be similar in spirit to the present version, but may differ in detail to address
524new problems or concerns.
525
526Each version is given a distinguishing version number. If the Program specifies
527that a certain numbered version of the GNU Affero General Public License "or
528any later version" applies to it, you have the option of following the terms
529and conditions either of that numbered version or of any later version published
530by the Free Software Foundation. If the Program does not specify a version
531number of the GNU Affero General Public License, you may choose any version
532ever published by the Free Software Foundation.
533
534If the Program specifies that a proxy can decide which future versions of
535the GNU Affero General Public License can be used, that proxy's public statement
536of acceptance of a version permanently authorizes you to choose that version
537for the Program.
538
539Later license versions may give you additional or different permissions. However,
540no additional obligations are imposed on any author or copyright holder as
541a result of your choosing to follow a later version.
542
543 15. Disclaimer of Warranty.
544
545THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
546LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
547OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
548EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES
549OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
550TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
551PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
552CORRECTION.
553
554 16. Limitation of Liability.
555
556IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
557ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM
558AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
559INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO
560USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
561INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
562PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
563PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
564
565 17. Interpretation of Sections 15 and 16.
566
567If the disclaimer of warranty and limitation of liability provided above cannot
568be given local legal effect according to their terms, reviewing courts shall
569apply local law that most closely approximates an absolute waiver of all civil
570liability in connection with the Program, unless a warranty or assumption
571of liability accompanies a copy of the Program in return for a fee. END OF
572TERMS AND CONDITIONS
573
574How to Apply These Terms to Your New Programs
575
576If you develop a new program, and you want it to be of the greatest possible
577use to the public, the best way to achieve this is to make it free software
578which everyone can redistribute and change under these terms.
579
580To do so, attach the following notices to the program. It is safest to attach
581them to the start of each source file to most effectively state the exclusion
582of warranty; and each file should have at least the "copyright" line and a
583pointer to where the full notice is found.
584
585<one line to give the program's name and a brief idea of what it does.>
586
587Copyright (C) <year> <name of author>
588
589This program is free software: you can redistribute it and/or modify it under
590the terms of the GNU Affero General Public License as published by the Free
591Software Foundation, either version 3 of the License, or (at your option)
592any later version.
593
594This program is distributed in the hope that it will be useful, but WITHOUT
595ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS
596FOR A PARTICULAR PURPOSE. See the GNU Affero General Public License for more
597details.
598
599You should have received a copy of the GNU Affero General Public License along
600with this program. If not, see <https://www.gnu.org/licenses/>.
601
602Also add information on how to contact you by electronic and paper mail.
603
604If your software can interact with users remotely through a computer network,
605you should also make sure that it provides a way for users to get its source.
606For example, if your program is a web application, its interface could display
607a "Source" link that leads users to an archive of the code. There are many
608ways you could offer source, and different solutions will be better for different
609programs; see section 13 for the specific requirements.
610
611You should also get your employer (if you work as a programmer) or school,
612if any, to sign a "copyright disclaimer" for the program, if necessary. For
613more information on this, and how to apply and follow the GNU AGPL, see <https://www.gnu.org/licenses/>.
