1 root 1.2 GNU AFFERO GENERAL PUBLIC LICENSE
2 root 1.3 Version 3, 19 November 2007
3 root 1.1
4 root 1.2 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
5 root 1.1 Everyone is permitted to copy and distribute verbatim copies
6     of this license document, but changing it is not allowed.
7    
8 root 1.2 Preamble
9 root 1.1
10     The GNU Affero General Public License is a free, copyleft license
11     for 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
15     designed to take away your freedom to share and change the works. By
16     contrast, our General Public Licenses are intended to guarantee your
17     freedom to share and change all versions of a program--to make sure it
18     remains free 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 root 1.3 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 root 1.1 The precise terms and conditions for copying, distribution and
57     modification follow.
58    
59 root 1.2 TERMS AND CONDITIONS
60 root 1.1
61 root 1.2 0. Definitions.
62 root 1.1
63     "This License" refers to version 3 of the GNU Affero General Public
64     License.
65    
66 root 1.3 "Copyright" also means copyright-like laws that apply to other kinds
67     of works, such as semiconductor masks.
68    
69 root 1.1 "The Program" refers to any copyrightable work licensed under this
70 root 1.2 License. Each licensee is addressed as "you". "Licensees" and
71 root 1.1 "recipients" may be individuals or organizations.
72    
73 root 1.2 To "modify" a work means to copy from or adapt all or part of the work
74     in a fashion requiring copyright permission, other than the making of an
75     exact copy. The resulting work is called a "modified version" of the
76     earlier work or a work "based on" the earlier work.
77    
78     A "covered work" means either the unmodified Program or a work based
79     on the Program.
80 root 1.1
81     To "propagate" a work means to do anything with it that, without
82     permission, would make you directly or secondarily liable for
83     infringement under applicable copyright law, except executing it on a
84 root 1.2 computer or modifying a private copy. Propagation includes copying,
85     distribution (with or without modification), making available to the
86     public, and in some countries other activities as well.
87    
88     To "convey" a work means any kind of propagation that enables other
89     parties to make or receive copies. Mere interaction with a user through
90     a computer network, with no transfer of a copy, is not conveying.
91 root 1.1
92     An interactive user interface displays "Appropriate Legal Notices"
93     to the extent that it includes a convenient and prominently visible
94     feature that (1) displays an appropriate copyright notice, and (2)
95     tells the user that there is no warranty for the work (except to the
96     extent that warranties are provided), that licensees may convey the
97     work under this License, and how to view a copy of this License. If
98     the interface presents a list of user commands or options, such as a
99     menu, a prominent item in the list meets this criterion.
100    
101 root 1.2 1. Source Code.
102 root 1.1
103     The "source code" for a work means the preferred form of the work
104     for making modifications to it. "Object code" means any non-source
105     form of a work.
106    
107     A "Standard Interface" means an interface that either is an official
108     standard defined by a recognized standards body, or, in the case of
109     interfaces specified for a particular programming language, one that
110     is widely used among developers working in that language.
111    
112     The "System Libraries" of an executable work include anything, other
113     than the work as a whole, that (a) is included in the normal form of
114     packaging a Major Component, but which is not part of that Major
115     Component, and (b) serves only to enable use of the work with that
116     Major Component, or to implement a Standard Interface for which an
117     implementation is available to the public in source code form. A
118     "Major Component", in this context, means a major essential component
119     (kernel, window system, and so on) of the specific operating system
120     (if any) on which the executable work runs, or a compiler used to
121     produce the work, or an object code interpreter used to run it.
122    
123     The "Corresponding Source" for a work in object code form means all
124     the source code needed to generate, install, and (for an executable
125     work) run the object code and to modify the work, including scripts to
126     control those activities. However, it does not include the work's
127     System Libraries, or general-purpose tools or generally available free
128     programs which are used unmodified in performing those activities but
129     which are not part of the work. For example, Corresponding Source
130     includes interface definition files associated with source files for
131     the work, and the source code for shared libraries and dynamically
132     linked subprograms that the work is specifically designed to require,
133     such as by intimate data communication or control flow between those
134     subprograms and other parts of the work.
135    
136     The Corresponding Source need not include anything that users
137     can regenerate automatically from other parts of the Corresponding
138     Source.
139    
140     The Corresponding Source for a work in source code form is that
141     same work.
142    
143 root 1.2 2. Basic Permissions.
144 root 1.1
145     All rights granted under this License are granted for the term of
146     copyright on the Program, and are irrevocable provided the stated
147     conditions are met. This License explicitly affirms your unlimited
148     permission to run the unmodified Program. The output from running a
149     covered work is covered by this License only if the output, given its
150     content, constitutes a covered work. This License acknowledges your
151     rights of fair use or other equivalent, as provided by copyright law.
152    
153     You may make, run and propagate covered works that you do not
154     convey, without conditions so long as your license otherwise remains
155     in force. You may convey covered works to others for the sole purpose
156     of having them make modifications exclusively for you, or provide you
157     with facilities for running those works, provided that you comply with
158     the terms of this License in conveying all material for which you do
159 root 1.2 not control copyright. Those thus making or running the covered works
160 root 1.1 for you must do so exclusively on your behalf, under your direction
161     and control, on terms that prohibit them from making any copies of
162     your copyrighted material outside their relationship with you.
163    
164     Conveying under any other circumstances is permitted solely under
165     the conditions stated below. Sublicensing is not allowed; section 10
166     makes it unnecessary.
167    
168 root 1.2 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
169 root 1.1
170     No covered work shall be deemed part of an effective technological
171     measure under any applicable law fulfilling obligations under article
172     11 of the WIPO copyright treaty adopted on 20 December 1996, or
173     similar laws prohibiting or restricting circumvention of such
174     measures.
175    
176     When you convey a covered work, you waive any legal power to forbid
177 root 1.2 circumvention of technological measures to the extent such circumvention
178 root 1.1 is effected by exercising rights under this License with respect to
179     the covered work, and you disclaim any intention to limit operation or
180     modification of the work as a means of enforcing, against the work's
181     users, your or third parties' legal rights to forbid circumvention of
182 root 1.2 technological measures.
183 root 1.1
184 root 1.2 4. Conveying Verbatim Copies.
185 root 1.1
186     You may convey verbatim copies of the Program's source code as you
187     receive it, in any medium, provided that you conspicuously and
188     appropriately publish on each copy an appropriate copyright notice;
189     keep intact all notices stating that this License and any
190     non-permissive terms added in accord with section 7 apply to the code;
191     keep intact all notices of the absence of any warranty; and give all
192     recipients a copy of this License along with the Program.
193    
194     You may charge any price or no price for each copy that you convey,
195     and you may offer support or warranty protection for a fee.
196    
197 root 1.2 5. Conveying Modified Source Versions.
198 root 1.1
199     You may convey a work based on the Program, or the modifications to
200     produce it from the Program, in the form of source code under the
201 root 1.2 terms of section 4, provided that you also meet all of these conditions:
202 root 1.1
203     a) The work must carry prominent notices stating that you modified
204     it, and giving a relevant date.
205    
206     b) The work must carry prominent notices stating that it is
207     released under this License and any conditions added under section
208     7. This requirement modifies the requirement in section 4 to
209     "keep intact all notices".
210    
211     c) You must license the entire work, as a whole, under this
212     License to anyone who comes into possession of a copy. This
213     License will therefore apply, along with any applicable section 7
214     additional terms, to the whole of the work, and all its parts,
215     regardless of how they are packaged. This License gives no
216     permission to license the work in any other way, but it does not
217     invalidate such permission if you have separately received it.
218    
219     d) If the work has interactive user interfaces, each must display
220     Appropriate Legal Notices; however, if the Program has interactive
221     interfaces that do not display Appropriate Legal Notices, your
222     work need not make them do so.
223    
224 root 1.2 A compilation of a covered work with other separate and independent
225 root 1.1 works, which are not by their nature extensions of the covered work,
226 root 1.2 and which are not combined with it such as to form a larger program,
227 root 1.1 in or on a volume of a storage or distribution medium, is called an
228     "aggregate" if the compilation and its resulting copyright are not
229     used to limit the access or legal rights of the compilation's users
230     beyond what the individual works permit. Inclusion of a covered work
231     in an aggregate does not cause this License to apply to the other
232     parts of the aggregate.
233    
234 root 1.2 6. Conveying Non-Source Forms.
235 root 1.1
236 root 1.2 You may convey a covered work in object code form under the terms
237 root 1.1 of sections 4 and 5, provided that you also convey the
238     machine-readable Corresponding Source under the terms of this License,
239     in one of these ways:
240    
241     a) Convey the object code in, or embodied in, a physical product
242     (including a physical distribution medium), accompanied by the
243     Corresponding Source fixed on a durable physical medium
244     customarily used for software interchange.
245    
246     b) Convey the object code in, or embodied in, a physical product
247     (including a physical distribution medium), accompanied by a
248     written offer, valid for at least three years and valid for as
249     long as you offer spare parts or customer support for that product
250 root 1.2 model, to give anyone who possesses the object code either (1) a
251 root 1.1 copy of the Corresponding Source for all the software in the
252     product that is covered by this License, on a durable physical
253     medium customarily used for software interchange, for a price no
254     more than your reasonable cost of physically performing this
255 root 1.2 conveying of source, or (2) access to copy the
256 root 1.1 Corresponding Source from a network server at no charge.
257    
258     c) Convey individual copies of the object code with a copy of the
259     written offer to provide the Corresponding Source. This
260     alternative is allowed only occasionally and noncommercially, and
261     only if you received the object code with such an offer, in accord
262     with subsection 6b.
263    
264     d) Convey the object code by offering access from a designated
265     place (gratis or for a charge), and offer equivalent access to the
266     Corresponding Source in the same way through the same place at no
267     further charge. You need not require recipients to copy the
268 root 1.2 Corresponding Source along with the object code. If the place to
269 root 1.1 copy the object code is a network server, the Corresponding Source
270     may be on a different server (operated by you or a third party)
271     that supports equivalent copying facilities, provided you maintain
272     clear directions next to the object code saying where to find the
273 root 1.2 Corresponding Source. Regardless of what server hosts the
274 root 1.1 Corresponding Source, you remain obligated to ensure that it is
275     available for as long as needed to satisfy these requirements.
276    
277     e) Convey the object code using peer-to-peer transmission, provided
278     you inform other peers where the object code and Corresponding
279     Source of the work are being offered to the general public at no
280     charge under subsection 6d.
281    
282 root 1.2 A separable portion of the object code, whose source code is excluded
283 root 1.1 from the Corresponding Source as a System Library, need not be
284     included in conveying the object code work.
285    
286 root 1.2 A "User Product" is either (1) a "consumer product", which means any
287     tangible personal property which is normally used for personal, family,
288     or household purposes, or (2) anything designed or sold for incorporation
289     into a dwelling. In determining whether a product is a consumer product,
290     doubtful cases shall be resolved in favor of coverage. For a particular
291     product received by a particular user, "normally used" refers to a
292     typical or common use of that class of product, regardless of the status
293     of the particular user or of the way in which the particular user
294     actually uses, or expects or is expected to use, the product. A product
295     is a consumer product regardless of whether the product has substantial
296     commercial, industrial or non-consumer uses, unless such uses represent
297     the only significant mode of use of the product.
298    
299     "Installation Information" for a User Product means any methods,
300     procedures, authorization keys, or other information required to install
301     and execute modified versions of a covered work in that User Product from
302     a modified version of its Corresponding Source. The information must
303     suffice to ensure that the continued functioning of the modified object
304     code is in no case prevented or interfered with solely because
305     modification has been made.
306 root 1.1
307 root 1.2 If you convey an object code work under this section in, or with, or
308 root 1.1 specifically for use in, a User Product, and the conveying occurs as
309     part of a transaction in which the right of possession and use of the
310     User Product is transferred to the recipient in perpetuity or for a
311     fixed term (regardless of how the transaction is characterized), the
312     Corresponding Source conveyed under this section must be accompanied
313     by the Installation Information. But this requirement does not apply
314     if neither you nor any third party retains the ability to install
315     modified object code on the User Product (for example, the work has
316     been installed in ROM).
317    
318 root 1.2 The requirement to provide Installation Information does not include a
319     requirement to continue to provide support service, warranty, or updates
320     for a work that has been modified or installed by the recipient, or for
321     the User Product in which it has been modified or installed. Access to a
322     network may be denied when the modification itself materially and
323     adversely affects the operation of the network or violates the rules and
324     protocols for communication across the network.
325 root 1.1
326 root 1.2 Corresponding Source conveyed, and Installation Information provided,
327 root 1.1 in accord with this section must be in a format that is publicly
328     documented (and with an implementation available to the public in
329     source code form), and must require no special password or key for
330     unpacking, reading or copying.
331    
332 root 1.2 7. Additional Terms.
333 root 1.1
334     "Additional permissions" are terms that supplement the terms of this
335     License by making exceptions from one or more of its conditions.
336     Additional permissions that are applicable to the entire Program shall
337     be treated as though they were included in this License, to the extent
338     that they are valid under applicable law. If additional permissions
339     apply only to part of the Program, that part may be used separately
340     under those permissions, but the entire Program remains governed by
341     this License without regard to the additional permissions.
342    
343     When you convey a copy of a covered work, you may at your option
344     remove any additional permissions from that copy, or from any part of
345     it. (Additional permissions may be written to require their own
346     removal in certain cases when you modify the work.) You may place
347     additional permissions on material, added by you to a covered work,
348     for which you have or can give appropriate copyright permission.
349    
350 root 1.2 Notwithstanding any other provision of this License, for material you
351     add to a covered work, you may (if authorized by the copyright holders of
352     that material) supplement the terms of this License with terms:
353    
354     a) Disclaiming warranty or limiting liability differently from the
355     terms of sections 15 and 16 of this License; or
356    
357     b) Requiring preservation of specified reasonable legal notices or
358     author attributions in that material or in the Appropriate Legal
359     Notices displayed by works containing it; or
360    
361     c) Prohibiting misrepresentation of the origin of that material, or
362     requiring that modified versions of such material be marked in
363     reasonable ways as different from the original version; or
364    
365     d) Limiting the use for publicity purposes of names of licensors or
366     authors of the material; or
367    
368     e) Declining to grant rights under trademark law for use of some
369     trade names, trademarks, or service marks; or
370    
371     f) Requiring indemnification of licensors and authors of that
372     material by anyone who conveys the material (or modified versions of
373     it) with contractual assumptions of liability to the recipient, for
374     any liability that these contractual assumptions directly impose on
375     those licensors and authors.
376 root 1.1
377     All other non-permissive additional terms are considered "further
378     restrictions" within the meaning of section 10. If the Program as you
379 root 1.2 received it, or any part of it, contains a notice stating that it is
380 root 1.3 governed by this License along with a term that is a further restriction,
381     you may remove that term. If a license document contains a further
382     restriction but permits relicensing or conveying under this License, you
383     may add to a covered work material governed by the terms of that license
384     document, provided that the further restriction does not survive such
385     relicensing or conveying.
386 root 1.1
387     If you add terms to a covered work in accord with this section, you
388     must place, in the relevant source files, a statement of the
389     additional terms that apply to those files, or a notice indicating
390     where to find the applicable terms.
391    
392     Additional terms, permissive or non-permissive, may be stated in the
393     form of a separately written license, or stated as exceptions;
394     the above requirements apply either way.
395    
396 root 1.2 8. Termination.
397 root 1.1
398     You may not propagate or modify a covered work except as expressly
399     provided under this License. Any attempt otherwise to propagate or
400 root 1.2 modify it is void, and will automatically terminate your rights under
401     this License (including any patent licenses granted under the third
402     paragraph of section 11).
403    
404     However, if you cease all violation of this License, then your
405     license from a particular copyright holder is reinstated (a)
406     provisionally, unless and until the copyright holder explicitly and
407     finally terminates your license, and (b) permanently, if the copyright
408     holder fails to notify you of the violation by some reasonable means
409     prior to 60 days after the cessation.
410    
411     Moreover, your license from a particular copyright holder is
412     reinstated permanently if the copyright holder notifies you of the
413     violation by some reasonable means, this is the first time you have
414     received notice of violation of this License (for any work) from that
415     copyright holder, and you cure the violation prior to 30 days after
416     your receipt of the notice.
417    
418     Termination of your rights under this section does not terminate the
419     licenses of parties who have received copies or rights from you under
420     this License. If your rights have been terminated and not permanently
421     reinstated, you do not qualify to receive new licenses for the same
422     material under section 10.
423 root 1.1
424 root 1.2 9. Acceptance Not Required for Having Copies.
425 root 1.1
426     You are not required to accept this License in order to receive or
427     run a copy of the Program. Ancillary propagation of a covered work
428     occurring solely as a consequence of using peer-to-peer transmission
429     to receive a copy likewise does not require acceptance. However,
430     nothing other than this License grants you permission to propagate or
431     modify any covered work. These actions infringe copyright if you do
432     not accept this License. Therefore, by modifying or propagating a
433     covered work, you indicate your acceptance of this License to do so.
434    
435 root 1.2 10. Automatic Licensing of Downstream Recipients.
436 root 1.1
437     Each time you convey a covered work, the recipient automatically
438     receives a license from the original licensors, to run, modify and
439     propagate that work, subject to this License. You are not responsible
440     for enforcing compliance by third parties with this License.
441    
442     An "entity transaction" is a transaction transferring control of an
443     organization, or substantially all assets of one, or subdividing an
444     organization, or merging organizations. If propagation of a covered
445     work results from an entity transaction, each party to that
446     transaction who receives a copy of the work also receives whatever
447     licenses to the work the party's predecessor in interest had or could
448     give under the previous paragraph, plus a right to possession of the
449     Corresponding Source of the work from the predecessor in interest, if
450     the predecessor has it or can get it with reasonable efforts.
451    
452     You may not impose any further restrictions on the exercise of the
453     rights granted or affirmed under this License. For example, you may
454     not impose a license fee, royalty, or other charge for exercise of
455     rights granted under this License, and you may not initiate litigation
456     (including a cross-claim or counterclaim in a lawsuit) alleging that
457     any patent claim is infringed by making, using, selling, offering for
458     sale, or importing the Program or any portion of it.
459    
460     11. Patents.
461    
462     A "contributor" is a copyright holder who authorizes use under this
463     License of the Program or a work on which the Program is based. The
464 root 1.2 work thus licensed is called the contributor's "contributor version".
465 root 1.1
466     A contributor's "essential patent claims" are all patent claims
467     owned or controlled by the contributor, whether already acquired or
468     hereafter acquired, that would be infringed by some manner, permitted
469     by this License, of making, using, or selling its contributor version,
470     but do not include claims that would be infringed only as a
471     consequence of further modification of the contributor version. For
472     purposes of this definition, "control" includes the right to grant
473     patent sublicenses in a manner consistent with the requirements of
474     this License.
475    
476     Each contributor grants you a non-exclusive, worldwide, royalty-free
477     patent license under the contributor's essential patent claims, to
478     make, use, sell, offer for sale, import and otherwise run, modify and
479     propagate the contents of its contributor version.
480    
481 root 1.2 In the following three paragraphs, a "patent license" is any express
482     agreement or commitment, however denominated, not to enforce a patent
483     (such as an express permission to practice a patent or covenant not to
484     sue for patent infringement). To "grant" such a patent license to a
485     party means to make such an agreement or commitment not to enforce a
486     patent against the party.
487 root 1.1
488     If you convey a covered work, knowingly relying on a patent license,
489     and the Corresponding Source of the work is not available for anyone
490     to copy, free of charge and under the terms of this License, through a
491     publicly available network server or other readily accessible means,
492     then you must either (1) cause the Corresponding Source to be so
493 root 1.2 available, or (2) arrange to deprive yourself of the benefit of the
494     patent license for this particular work, or (3) arrange, in a manner
495     consistent with the requirements of this License, to extend the patent
496     license to downstream recipients. "Knowingly relying" means you have
497     actual knowledge that, but for the patent license, your conveying the
498     covered work in a country, or your recipient's use of the covered work
499     in a country, would infringe one or more identifiable patents in that
500     country that you have reason to believe are valid.
501    
502 root 1.1 If, pursuant to or in connection with a single transaction or
503     arrangement, you convey, or propagate by procuring conveyance of, a
504     covered work, and grant a patent license to some of the parties
505     receiving the covered work authorizing them to use, propagate, modify
506     or convey a specific copy of the covered work, then the patent license
507     you grant is automatically extended to all recipients of the covered
508     work and works based on it.
509    
510     A patent license is "discriminatory" if it does not include within
511     the scope of its coverage, prohibits the exercise of, or is
512     conditioned on the non-exercise of one or more of the rights that are
513     specifically granted under this License. You may not convey a covered
514     work if you are a party to an arrangement with a third party that is
515     in the business of distributing software, under which you make payment
516     to the third party based on the extent of your activity of conveying
517     the work, and under which the third party grants, to any of the
518     parties who would receive the covered work from you, a discriminatory
519     patent license (a) in connection with copies of the covered work
520     conveyed by you (or copies made from those copies), or (b) primarily
521     for and in connection with specific products or compilations that
522     contain the covered work, unless you entered into that arrangement,
523     or that patent license was granted, prior to 28 March 2007.
524    
525     Nothing in this License shall be construed as excluding or limiting
526     any implied license or other defenses to infringement that may
527     otherwise be available to you under applicable patent law.
528    
529 root 1.2 12. No Surrender of Others' Freedom.
530 root 1.1
531     If conditions are imposed on you (whether by court order, agreement or
532     otherwise) that contradict the conditions of this License, they do not
533 root 1.2 excuse you from the conditions of this License. If you cannot convey a
534     covered work so as to satisfy simultaneously your obligations under this
535     License and any other pertinent obligations, then as a consequence you may
536     not convey it at all. For example, if you agree to terms that obligate you
537     to collect a royalty for further conveying from those to whom you convey
538     the Program, the only way you could satisfy both those terms and this
539     License would be to refrain entirely from conveying the Program.
540 root 1.1
541     13. Remote Network Interaction; Use with the GNU General Public License.
542    
543 root 1.2 Notwithstanding any other provision of this License, if you modify the
544     Program, your modified version must prominently offer all users
545     interacting with it remotely through a computer network (if your version
546     supports such interaction) an opportunity to receive the Corresponding
547     Source of your version by providing access to the Corresponding Source
548     from a network server at no charge, through some standard or customary
549     means of facilitating copying of software. This Corresponding Source
550     shall include the Corresponding Source for any work covered by version 3
551     of the GNU General Public License that is incorporated pursuant to the
552     following paragraph.
553    
554     Notwithstanding any other provision of this License, you have permission
555     to link or combine any covered work with a work licensed under version 3
556     of the GNU General Public License into a single combined work, and to
557     convey the resulting work. The terms of this License will continue to
558     apply to the part which is the covered work, but the work with which it is
559     combined will remain governed by version 3 of the GNU General Public
560     License.
561    
562     14. Revised Versions of this License.
563    
564     The Free Software Foundation may publish revised and/or new versions of
565     the GNU Affero General Public License from time to time. Such new
566     versions will be similar in spirit to the present version, but may differ
567     in detail to address new problems or concerns.
568    
569 root 1.3 Each version is given a distinguishing version number. If the
570     Program specifies that a certain numbered version of the GNU Affero
571     General Public License "or any later version" applies to it, you have
572     the option of following the terms and conditions either of that
573     numbered version or of any later version published by the Free
574     Software Foundation. If the Program does not specify a version number
575     of the GNU Affero General Public License, you may choose any version
576     ever published by the Free Software Foundation.
577    
578     If the Program specifies that a proxy can decide which future
579     versions of the GNU Affero General Public License can be used, that
580     proxy's public statement of acceptance of a version permanently
581     authorizes you to choose that version for the Program.
582 root 1.1
583 root 1.2 Later license versions may give you additional or different
584 root 1.1 permissions. However, no additional obligations are imposed on any
585     author or copyright holder as a result of your choosing to follow a
586     later version.
587    
588 root 1.2 15. Disclaimer of Warranty.
589 root 1.1
590     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
591     APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
592     HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
593     OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
594     THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
595     PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
596     IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
597     ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
598    
599 root 1.2 16. Limitation of Liability.
600 root 1.1
601     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
602     WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
603     THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
604     GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
605     USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
606     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
607     PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
608     EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
609     SUCH DAMAGES.
610    
611     17. Interpretation of Sections 15 and 16.
612    
613     If the disclaimer of warranty and limitation of liability provided
614     above cannot be given local legal effect according to their terms,
615     reviewing courts shall apply local law that most closely approximates
616     an absolute waiver of all civil liability in connection with the
617     Program, unless a warranty or assumption of liability accompanies a
618     copy of the Program in return for a fee.
619    
620 root 1.3 END OF TERMS AND CONDITIONS
621 root 1.1
622 root 1.3 How to Apply These Terms to Your New Programs
623 root 1.1
624     If you develop a new program, and you want it to be of the greatest
625     possible use to the public, the best way to achieve this is to make it
626     free software which everyone can redistribute and change under these terms.
627    
628     To do so, attach the following notices to the program. It is safest
629     to attach them to the start of each source file to most effectively
630     state the exclusion of warranty; and each file should have at least
631     the "copyright" line and a pointer to where the full notice is found.
632    
633     <one line to give the program's name and a brief idea of what it does.>
634     Copyright (C) <year> <name of author>
635    
636 root 1.2 This program is free software: you can redistribute it and/or modify
637 root 1.3 it under the terms of the GNU Affero General Public License as
638     published by the Free Software Foundation, either version 3 of the
639     License, or (at your option) any later version.
640 root 1.1
641     This program is distributed in the hope that it will be useful,
642     but WITHOUT ANY WARRANTY; without even the implied warranty of
643     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
644     GNU Affero General Public License for more details.
645    
646     You should have received a copy of the GNU Affero General Public License
647 root 1.2 along with this program. If not, see <http://www.gnu.org/licenses/>.
648 root 1.1
649     Also add information on how to contact you by electronic and paper mail.
650    
651 root 1.3 If your software can interact with users remotely through a computer
652     network, you should also make sure that it provides a way for users to
653     get its source. For example, if your program is a web application, its
654     interface could display a "Source" link that leads users to an archive
655     of the code. There are many ways you could offer source, and different
656     solutions will be better for different programs; see section 13 for the
657     specific requirements.
658 root 1.2
659     You should also get your employer (if you work as a programmer) or school,
660     if any, to sign a "copyright disclaimer" for the program, if necessary.
