1 root 1.2 GNU AFFERO GENERAL PUBLIC LICENSE
2     Last Call Draft (2) of Version 3, 14 August 2007
3 root 1.1
4 root 1.2 THIS IS A DRAFT, NOT A PUBLISHED VERSION OF THE GNU AFFERO GENERAL PUBLIC
5     LICENSE.
6 root 1.1
7 root 1.2 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
8 root 1.1 Everyone is permitted to copy and distribute verbatim copies
9     of this license document, but changing it is not allowed.
10    
11 root 1.2 Preamble
12 root 1.1
13     The GNU Affero General Public License is a free, copyleft license
14     for software and other kinds of works, specifically designed to ensure
15     cooperation with the community in the case of network server software.
16    
17     The licenses for most software and other practical works are
18     designed to take away your freedom to share and change the works. By
19     contrast, our General Public Licenses are intended to guarantee your
20     freedom to share and change all versions of a program--to make sure it
21     remains free software for all its users.
22    
23     When we speak of free software, we are referring to freedom, not
24     price. Our General Public Licenses are designed to make sure that you
25     have the freedom to distribute copies of free software (and charge for
26     them if you wish), that you receive source code or can get it if you
27     want it, that you can change the software or use pieces of it in new
28     free programs, and that you know you can do these things.
29    
30     Developers that use our General Public Licenses protect your rights
31     with two steps: (1) assert copyright on the software, and (2) offer
32     you this License which gives you legal permission to copy, distribute
33     and/or modify the software.
34    
35     A secondary benefit of defending all users' freedom is that
36     improvements made in alternate versions of the program, if they
37     receive widespread use, become available for other developers to
38     incorporate. Many developers of free software are heartened and
39     encouraged by the resulting cooperation. However, in the case of
40     software used on network servers, this result may fail to come about.
41     The GNU General Public License permits making a modified version and
42     letting the public access it on a server without ever releasing its
43     source code to the public.
44    
45     The GNU Affero General Public License is designed specifically to
46     ensure that, in such cases, the modified source code becomes available
47     to the community. It requires the operator of a network server to
48     provide the source code of the modified version running there to the
49     users of that server. Therefore, public use of a modified version, on
50     a publicly accessible server, gives the public access to the source
51     code of the modified version.
52    
53     The precise terms and conditions for copying, distribution and
54     modification follow.
55    
56 root 1.2 TERMS AND CONDITIONS
57 root 1.1
58 root 1.2 0. Definitions.
59 root 1.1
60     "This License" refers to version 3 of the GNU Affero General Public
61     License.
62    
63 root 1.2 "Copyright" also means copyright-like laws that apply to other kinds of
64     works, such as semiconductor masks.
65    
66 root 1.1 "The Program" refers to any copyrightable work licensed under this
67 root 1.2 License. Each licensee is addressed as "you". "Licensees" and
68 root 1.1 "recipients" may be individuals or organizations.
69    
70 root 1.2 To "modify" a work means to copy from or adapt all or part of the work
71     in a fashion requiring copyright permission, other than the making of an
72     exact copy. The resulting work is called a "modified version" of the
73     earlier work or a work "based on" the earlier work.
74    
75     A "covered work" means either the unmodified Program or a work based
76     on the Program.
77 root 1.1
78     To "propagate" a work means to do anything with it that, without
79     permission, would make you directly or secondarily liable for
80     infringement under applicable copyright law, except executing it on a
81 root 1.2 computer or modifying a private copy. Propagation includes copying,
82     distribution (with or without modification), making available to the
83     public, and in some countries other activities as well.
84    
85     To "convey" a work means any kind of propagation that enables other
86     parties to make or receive copies. Mere interaction with a user through
87     a computer network, with no transfer of a copy, is not conveying.
88 root 1.1
89     An interactive user interface displays "Appropriate Legal Notices"
90     to the extent that it includes a convenient and prominently visible
91     feature that (1) displays an appropriate copyright notice, and (2)
92     tells the user that there is no warranty for the work (except to the
93     extent that warranties are provided), that licensees may convey the
94     work under this License, and how to view a copy of this License. If
95     the interface presents a list of user commands or options, such as a
96     menu, a prominent item in the list meets this criterion.
97    
98 root 1.2 1. Source Code.
99 root 1.1
100     The "source code" for a work means the preferred form of the work
101     for making modifications to it. "Object code" means any non-source
102     form of a work.
103    
104     A "Standard Interface" means an interface that either is an official
105     standard defined by a recognized standards body, or, in the case of
106     interfaces specified for a particular programming language, one that
107     is widely used among developers working in that language.
108    
109     The "System Libraries" of an executable work include anything, other
110     than the work as a whole, that (a) is included in the normal form of
111     packaging a Major Component, but which is not part of that Major
112     Component, and (b) serves only to enable use of the work with that
113     Major Component, or to implement a Standard Interface for which an
114     implementation is available to the public in source code form. A
115     "Major Component", in this context, means a major essential component
116     (kernel, window system, and so on) of the specific operating system
117     (if any) on which the executable work runs, or a compiler used to
118     produce the work, or an object code interpreter used to run it.
119    
120     The "Corresponding Source" for a work in object code form means all
121     the source code needed to generate, install, and (for an executable
122     work) run the object code and to modify the work, including scripts to
123     control those activities. However, it does not include the work's
124     System Libraries, or general-purpose tools or generally available free
125     programs which are used unmodified in performing those activities but
126     which are not part of the work. For example, Corresponding Source
127     includes interface definition files associated with source files for
128     the work, and the source code for shared libraries and dynamically
129     linked subprograms that the work is specifically designed to require,
130     such as by intimate data communication or control flow between those
131     subprograms and other parts of the work.
132    
133     The Corresponding Source need not include anything that users
134     can regenerate automatically from other parts of the Corresponding
135     Source.
136    
137     The Corresponding Source for a work in source code form is that
138     same work.
139    
140 root 1.2 2. Basic Permissions.
141 root 1.1
142     All rights granted under this License are granted for the term of
143     copyright on the Program, and are irrevocable provided the stated
144     conditions are met. This License explicitly affirms your unlimited
145     permission to run the unmodified Program. The output from running a
146     covered work is covered by this License only if the output, given its
147     content, constitutes a covered work. This License acknowledges your
148     rights of fair use or other equivalent, as provided by copyright law.
149    
150     You may make, run and propagate covered works that you do not
151     convey, without conditions so long as your license otherwise remains
152     in force. You may convey covered works to others for the sole purpose
153     of having them make modifications exclusively for you, or provide you
154     with facilities for running those works, provided that you comply with
155     the terms of this License in conveying all material for which you do
156 root 1.2 not control copyright. Those thus making or running the covered works
157 root 1.1 for you must do so exclusively on your behalf, under your direction
158     and control, on terms that prohibit them from making any copies of
159     your copyrighted material outside their relationship with you.
160    
161     Conveying under any other circumstances is permitted solely under
162     the conditions stated below. Sublicensing is not allowed; section 10
163     makes it unnecessary.
164    
165 root 1.2 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
166 root 1.1
167     No covered work shall be deemed part of an effective technological
168     measure under any applicable law fulfilling obligations under article
169     11 of the WIPO copyright treaty adopted on 20 December 1996, or
170     similar laws prohibiting or restricting circumvention of such
171     measures.
172    
173     When you convey a covered work, you waive any legal power to forbid
174 root 1.2 circumvention of technological measures to the extent such circumvention
175 root 1.1 is effected by exercising rights under this License with respect to
176     the covered work, and you disclaim any intention to limit operation or
177     modification of the work as a means of enforcing, against the work's
178     users, your or third parties' legal rights to forbid circumvention of
179 root 1.2 technological measures.
180 root 1.1
181 root 1.2 4. Conveying Verbatim Copies.
182 root 1.1
183     You may convey verbatim copies of the Program's source code as you
184     receive it, in any medium, provided that you conspicuously and
185     appropriately publish on each copy an appropriate copyright notice;
186     keep intact all notices stating that this License and any
187     non-permissive terms added in accord with section 7 apply to the code;
188     keep intact all notices of the absence of any warranty; and give all
189     recipients a copy of this License along with the Program.
190    
191     You may charge any price or no price for each copy that you convey,
192     and you may offer support or warranty protection for a fee.
193    
194 root 1.2 5. Conveying Modified Source Versions.
195 root 1.1
196     You may convey a work based on the Program, or the modifications to
197     produce it from the Program, in the form of source code under the
198 root 1.2 terms of section 4, provided that you also meet all of these conditions:
199 root 1.1
200     a) The work must carry prominent notices stating that you modified
201     it, and giving a relevant date.
202    
203     b) The work must carry prominent notices stating that it is
204     released under this License and any conditions added under section
205     7. This requirement modifies the requirement in section 4 to
206     "keep intact all notices".
207    
208     c) You must license the entire work, as a whole, under this
209     License to anyone who comes into possession of a copy. This
210     License will therefore apply, along with any applicable section 7
211     additional terms, to the whole of the work, and all its parts,
212     regardless of how they are packaged. This License gives no
213     permission to license the work in any other way, but it does not
214     invalidate such permission if you have separately received it.
215    
216     d) If the work has interactive user interfaces, each must display
217     Appropriate Legal Notices; however, if the Program has interactive
218     interfaces that do not display Appropriate Legal Notices, your
219     work need not make them do so.
220    
221 root 1.2 A compilation of a covered work with other separate and independent
222 root 1.1 works, which are not by their nature extensions of the covered work,
223 root 1.2 and which are not combined with it such as to form a larger program,
224 root 1.1 in or on a volume of a storage or distribution medium, is called an
225     "aggregate" if the compilation and its resulting copyright are not
226     used to limit the access or legal rights of the compilation's users
227     beyond what the individual works permit. Inclusion of a covered work
228     in an aggregate does not cause this License to apply to the other
229     parts of the aggregate.
230    
231 root 1.2 6. Conveying Non-Source Forms.
232 root 1.1
233 root 1.2 You may convey a covered work in object code form under the terms
234 root 1.1 of sections 4 and 5, provided that you also convey the
235     machine-readable Corresponding Source under the terms of this License,
236     in one of these ways:
237    
238     a) Convey the object code in, or embodied in, a physical product
239     (including a physical distribution medium), accompanied by the
240     Corresponding Source fixed on a durable physical medium
241     customarily used for software interchange.
242    
243     b) Convey the object code in, or embodied in, a physical product
244     (including a physical distribution medium), accompanied by a
245     written offer, valid for at least three years and valid for as
246     long as you offer spare parts or customer support for that product
247 root 1.2 model, to give anyone who possesses the object code either (1) a
248 root 1.1 copy of the Corresponding Source for all the software in the
249     product that is covered by this License, on a durable physical
250     medium customarily used for software interchange, for a price no
251     more than your reasonable cost of physically performing this
252 root 1.2 conveying of source, or (2) access to copy the
253 root 1.1 Corresponding Source from a network server at no charge.
254    
255     c) Convey individual copies of the object code with a copy of the
256     written offer to provide the Corresponding Source. This
257     alternative is allowed only occasionally and noncommercially, and
258     only if you received the object code with such an offer, in accord
259     with subsection 6b.
260    
261     d) Convey the object code by offering access from a designated
262     place (gratis or for a charge), and offer equivalent access to the
263     Corresponding Source in the same way through the same place at no
264     further charge. You need not require recipients to copy the
265 root 1.2 Corresponding Source along with the object code. If the place to
266 root 1.1 copy the object code is a network server, the Corresponding Source
267     may be on a different server (operated by you or a third party)
268     that supports equivalent copying facilities, provided you maintain
269     clear directions next to the object code saying where to find the
270 root 1.2 Corresponding Source. Regardless of what server hosts the
271 root 1.1 Corresponding Source, you remain obligated to ensure that it is
272     available for as long as needed to satisfy these requirements.
273    
274     e) Convey the object code using peer-to-peer transmission, provided
275     you inform other peers where the object code and Corresponding
276     Source of the work are being offered to the general public at no
277     charge under subsection 6d.
278    
279 root 1.2 A separable portion of the object code, whose source code is excluded
280 root 1.1 from the Corresponding Source as a System Library, need not be
281     included in conveying the object code work.
282    
283 root 1.2 A "User Product" is either (1) a "consumer product", which means any
284     tangible personal property which is normally used for personal, family,
285     or household purposes, or (2) anything designed or sold for incorporation
286     into a dwelling. In determining whether a product is a consumer product,
287     doubtful cases shall be resolved in favor of coverage. For a particular
288     product received by a particular user, "normally used" refers to a
289     typical or common use of that class of product, regardless of the status
290     of the particular user or of the way in which the particular user
291     actually uses, or expects or is expected to use, the product. A product
292     is a consumer product regardless of whether the product has substantial
293     commercial, industrial or non-consumer uses, unless such uses represent
294     the only significant mode of use of the product.
295    
296     "Installation Information" for a User Product means any methods,
297     procedures, authorization keys, or other information required to install
298     and execute modified versions of a covered work in that User Product from
299     a modified version of its Corresponding Source. The information must
300     suffice to ensure that the continued functioning of the modified object
301     code is in no case prevented or interfered with solely because
302     modification has been made.
303 root 1.1
304 root 1.2 If you convey an object code work under this section in, or with, or
305 root 1.1 specifically for use in, a User Product, and the conveying occurs as
306     part of a transaction in which the right of possession and use of the
307     User Product is transferred to the recipient in perpetuity or for a
308     fixed term (regardless of how the transaction is characterized), the
309     Corresponding Source conveyed under this section must be accompanied
310     by the Installation Information. But this requirement does not apply
311     if neither you nor any third party retains the ability to install
312     modified object code on the User Product (for example, the work has
313     been installed in ROM).
314    
315 root 1.2 The requirement to provide Installation Information does not include a
316     requirement to continue to provide support service, warranty, or updates
317     for a work that has been modified or installed by the recipient, or for
318     the User Product in which it has been modified or installed. Access to a
319     network may be denied when the modification itself materially and
320     adversely affects the operation of the network or violates the rules and
321     protocols for communication across the network.
322 root 1.1
323 root 1.2 Corresponding Source conveyed, and Installation Information provided,
324 root 1.1 in accord with this section must be in a format that is publicly
325     documented (and with an implementation available to the public in
326     source code form), and must require no special password or key for
327     unpacking, reading or copying.
328    
329 root 1.2 7. Additional Terms.
330 root 1.1
331     "Additional permissions" are terms that supplement the terms of this
332     License by making exceptions from one or more of its conditions.
333     Additional permissions that are applicable to the entire Program shall
334     be treated as though they were included in this License, to the extent
335     that they are valid under applicable law. If additional permissions
336     apply only to part of the Program, that part may be used separately
337     under those permissions, but the entire Program remains governed by
338     this License without regard to the additional permissions.
339    
340     When you convey a copy of a covered work, you may at your option
341     remove any additional permissions from that copy, or from any part of
342     it. (Additional permissions may be written to require their own
343     removal in certain cases when you modify the work.) You may place
344     additional permissions on material, added by you to a covered work,
345     for which you have or can give appropriate copyright permission.
346    
347 root 1.2 Notwithstanding any other provision of this License, for material you
348     add to a covered work, you may (if authorized by the copyright holders of
349     that material) supplement the terms of this License with terms:
350    
351     a) Disclaiming warranty or limiting liability differently from the
352     terms of sections 15 and 16 of this License; or
353    
354     b) Requiring preservation of specified reasonable legal notices or
355     author attributions in that material or in the Appropriate Legal
356     Notices displayed by works containing it; or
357    
358     c) Prohibiting misrepresentation of the origin of that material, or
359     requiring that modified versions of such material be marked in
360     reasonable ways as different from the original version; or
361    
362     d) Limiting the use for publicity purposes of names of licensors or
363     authors of the material; or
364    
365     e) Declining to grant rights under trademark law for use of some
366     trade names, trademarks, or service marks; or
367    
368     f) Requiring indemnification of licensors and authors of that
369     material by anyone who conveys the material (or modified versions of
370     it) with contractual assumptions of liability to the recipient, for
371     any liability that these contractual assumptions directly impose on
372     those licensors and authors.
373 root 1.1
374     All other non-permissive additional terms are considered "further
375     restrictions" within the meaning of section 10. If the Program as you
376 root 1.2 received it, or any part of it, contains a notice stating that it is
377     governed by this License along with a term that is a further
378     restriction, you may remove that term. If a license document contains
379     a further restriction but permits relicensing or conveying under this
380     License, you may add to a covered work material governed by the terms
381     of that license document, provided that the further restriction does
382     not survive such relicensing or conveying.
383 root 1.1
384     If you add terms to a covered work in accord with this section, you
385     must place, in the relevant source files, a statement of the
386     additional terms that apply to those files, or a notice indicating
387     where to find the applicable terms.
388    
389     Additional terms, permissive or non-permissive, may be stated in the
390     form of a separately written license, or stated as exceptions;
391     the above requirements apply either way.
392    
393 root 1.2 8. Termination.
394 root 1.1
395     You may not propagate or modify a covered work except as expressly
396     provided under this License. Any attempt otherwise to propagate or
397 root 1.2 modify it is void, and will automatically terminate your rights under
398     this License (including any patent licenses granted under the third
399     paragraph of section 11).
400    
401     However, if you cease all violation of this License, then your
402     license from a particular copyright holder is reinstated (a)
403     provisionally, unless and until the copyright holder explicitly and
404     finally terminates your license, and (b) permanently, if the copyright
405     holder fails to notify you of the violation by some reasonable means
406     prior to 60 days after the cessation.
407    
408     Moreover, your license from a particular copyright holder is
409     reinstated permanently if the copyright holder notifies you of the
410     violation by some reasonable means, this is the first time you have
411     received notice of violation of this License (for any work) from that
412     copyright holder, and you cure the violation prior to 30 days after
413     your receipt of the notice.
414    
415     Termination of your rights under this section does not terminate the
416     licenses of parties who have received copies or rights from you under
417     this License. If your rights have been terminated and not permanently
418     reinstated, you do not qualify to receive new licenses for the same
419     material under section 10.
420 root 1.1
421 root 1.2 9. Acceptance Not Required for Having Copies.
422 root 1.1
423     You are not required to accept this License in order to receive or
424     run a copy of the Program. Ancillary propagation of a covered work
425     occurring solely as a consequence of using peer-to-peer transmission
426     to receive a copy likewise does not require acceptance. However,
427     nothing other than this License grants you permission to propagate or
428     modify any covered work. These actions infringe copyright if you do
429     not accept this License. Therefore, by modifying or propagating a
430     covered work, you indicate your acceptance of this License to do so.
431    
432 root 1.2 10. Automatic Licensing of Downstream Recipients.
433 root 1.1
434     Each time you convey a covered work, the recipient automatically
435     receives a license from the original licensors, to run, modify and
436     propagate that work, subject to this License. You are not responsible
437     for enforcing compliance by third parties with this License.
438    
439     An "entity transaction" is a transaction transferring control of an
440     organization, or substantially all assets of one, or subdividing an
441     organization, or merging organizations. If propagation of a covered
442     work results from an entity transaction, each party to that
443     transaction who receives a copy of the work also receives whatever
444     licenses to the work the party's predecessor in interest had or could
445     give under the previous paragraph, plus a right to possession of the
446     Corresponding Source of the work from the predecessor in interest, if
447     the predecessor has it or can get it with reasonable efforts.
448    
449     You may not impose any further restrictions on the exercise of the
450     rights granted or affirmed under this License. For example, you may
451     not impose a license fee, royalty, or other charge for exercise of
452     rights granted under this License, and you may not initiate litigation
453     (including a cross-claim or counterclaim in a lawsuit) alleging that
454     any patent claim is infringed by making, using, selling, offering for
455     sale, or importing the Program or any portion of it.
456    
457     11. Patents.
458    
459     A "contributor" is a copyright holder who authorizes use under this
460     License of the Program or a work on which the Program is based. The
461 root 1.2 work thus licensed is called the contributor's "contributor version".
462 root 1.1
463     A contributor's "essential patent claims" are all patent claims
464     owned or controlled by the contributor, whether already acquired or
465     hereafter acquired, that would be infringed by some manner, permitted
466     by this License, of making, using, or selling its contributor version,
467     but do not include claims that would be infringed only as a
468     consequence of further modification of the contributor version. For
469     purposes of this definition, "control" includes the right to grant
470     patent sublicenses in a manner consistent with the requirements of
471     this License.
472    
473     Each contributor grants you a non-exclusive, worldwide, royalty-free
474     patent license under the contributor's essential patent claims, to
475     make, use, sell, offer for sale, import and otherwise run, modify and
476     propagate the contents of its contributor version.
477    
478 root 1.2 In the following three paragraphs, a "patent license" is any express
479     agreement or commitment, however denominated, not to enforce a patent
480     (such as an express permission to practice a patent or covenant not to
481     sue for patent infringement). To "grant" such a patent license to a
482     party means to make such an agreement or commitment not to enforce a
483     patent against the party.
484 root 1.1
485     If you convey a covered work, knowingly relying on a patent license,
486     and the Corresponding Source of the work is not available for anyone
487     to copy, free of charge and under the terms of this License, through a
488     publicly available network server or other readily accessible means,
489     then you must either (1) cause the Corresponding Source to be so
490 root 1.2 available, or (2) arrange to deprive yourself of the benefit of the
491     patent license for this particular work, or (3) arrange, in a manner
492     consistent with the requirements of this License, to extend the patent
493     license to downstream recipients. "Knowingly relying" means you have
494     actual knowledge that, but for the patent license, your conveying the
495     covered work in a country, or your recipient's use of the covered work
496     in a country, would infringe one or more identifiable patents in that
497     country that you have reason to believe are valid.
498    
499 root 1.1 If, pursuant to or in connection with a single transaction or
500     arrangement, you convey, or propagate by procuring conveyance of, a
501     covered work, and grant a patent license to some of the parties
502     receiving the covered work authorizing them to use, propagate, modify
503     or convey a specific copy of the covered work, then the patent license
504     you grant is automatically extended to all recipients of the covered
505     work and works based on it.
506    
507     A patent license is "discriminatory" if it does not include within
508     the scope of its coverage, prohibits the exercise of, or is
509     conditioned on the non-exercise of one or more of the rights that are
510     specifically granted under this License. You may not convey a covered
511     work if you are a party to an arrangement with a third party that is
512     in the business of distributing software, under which you make payment
513     to the third party based on the extent of your activity of conveying
514     the work, and under which the third party grants, to any of the
515     parties who would receive the covered work from you, a discriminatory
516     patent license (a) in connection with copies of the covered work
517     conveyed by you (or copies made from those copies), or (b) primarily
518     for and in connection with specific products or compilations that
519     contain the covered work, unless you entered into that arrangement,
520     or that patent license was granted, prior to 28 March 2007.
521    
522     Nothing in this License shall be construed as excluding or limiting
523     any implied license or other defenses to infringement that may
524     otherwise be available to you under applicable patent law.
525    
526 root 1.2 12. No Surrender of Others' Freedom.
527 root 1.1
528     If conditions are imposed on you (whether by court order, agreement or
529     otherwise) that contradict the conditions of this License, they do not
530 root 1.2 excuse you from the conditions of this License. If you cannot convey a
531     covered work so as to satisfy simultaneously your obligations under this
532     License and any other pertinent obligations, then as a consequence you may
533     not convey it at all. For example, if you agree to terms that obligate you
534     to collect a royalty for further conveying from those to whom you convey
535     the Program, the only way you could satisfy both those terms and this
536     License would be to refrain entirely from conveying the Program.
537 root 1.1
538     13. Remote Network Interaction; Use with the GNU General Public License.
539    
540 root 1.2 Notwithstanding any other provision of this License, if you modify the
541     Program, your modified version must prominently offer all users
542     interacting with it remotely through a computer network (if your version
543     supports such interaction) an opportunity to receive the Corresponding
544     Source of your version by providing access to the Corresponding Source
545     from a network server at no charge, through some standard or customary
546     means of facilitating copying of software. This Corresponding Source
547     shall include the Corresponding Source for any work covered by version 3
548     of the GNU General Public License that is incorporated pursuant to the
549     following paragraph.
550    
551     Notwithstanding any other provision of this License, you have permission
552     to link or combine any covered work with a work licensed under version 3
553     of the GNU General Public License into a single combined work, and to
554     convey the resulting work. The terms of this License will continue to
555     apply to the part which is the covered work, but the work with which it is
556     combined will remain governed by version 3 of the GNU General Public
557     License.
558    
559     14. Revised Versions of this License.
560    
561     The Free Software Foundation may publish revised and/or new versions of
562     the GNU Affero General Public License from time to time. Such new
563     versions will be similar in spirit to the present version, but may differ
564     in detail to address new problems or concerns.
565    
566     Each version is given a distinguishing version number. If the Program
567     specifies that a certain numbered version of the GNU Affero General
568     Public License "or any later version" applies to it, you have the option
569     of following the terms and conditions either of that numbered version or
570     of any later version published by the Free Software Foundation. If the
571     Program does not specify a version number of the GNU Affero General
572     Public License, you may choose any version ever published by the Free
573     Software Foundation.
574    
575     If the Program specifies that a proxy can decide which future versions
576     of the GNU Affero General Public License can be used, that proxy's
577     public statement of acceptance of a version permanently authorizes you
578     to choose that version for the Program.
579 root 1.1
580 root 1.2 Later license versions may give you additional or different
581 root 1.1 permissions. However, no additional obligations are imposed on any
582     author or copyright holder as a result of your choosing to follow a
583     later version.
584    
585 root 1.2 15. Disclaimer of Warranty.
586 root 1.1
587     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
588     APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
589     HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
590     OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
591     THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
592     PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
593     IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
594     ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
595    
596 root 1.2 16. Limitation of Liability.
597 root 1.1
598     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
599     WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
600     THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
601     GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
602     USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
603     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
604     PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
605     EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
606     SUCH DAMAGES.
607    
608     17. Interpretation of Sections 15 and 16.
609    
610     If the disclaimer of warranty and limitation of liability provided
611     above cannot be given local legal effect according to their terms,
612     reviewing courts shall apply local law that most closely approximates
613     an absolute waiver of all civil liability in connection with the
614     Program, unless a warranty or assumption of liability accompanies a
615     copy of the Program in return for a fee.
616    
617 root 1.2 END OF TERMS AND CONDITIONS
618 root 1.1
619 root 1.2 How to Apply These Terms to Your New Programs
620 root 1.1
621     If you develop a new program, and you want it to be of the greatest
622     possible use to the public, the best way to achieve this is to make it
623     free software which everyone can redistribute and change under these terms.
624    
625     To do so, attach the following notices to the program. It is safest
626     to attach them to the start of each source file to most effectively
627     state the exclusion of warranty; and each file should have at least
628     the "copyright" line and a pointer to where the full notice is found.
629    
630     <one line to give the program's name and a brief idea of what it does.>
631     Copyright (C) <year> <name of author>
632    
633 root 1.2 This program is free software: you can redistribute it and/or modify
634 root 1.1 it under the terms of the GNU Affero General Public License as published by
635 root 1.2 the Free Software Foundation, either version 3 of the License, or
636 root 1.1 (at your option) any later version.
637    
638     This program is distributed in the hope that it will be useful,
639     but WITHOUT ANY WARRANTY; without even the implied warranty of
640     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
641     GNU Affero General Public License for more details.
642    
643     You should have received a copy of the GNU Affero General Public License
644 root 1.2 along with this program. If not, see <http://www.gnu.org/licenses/>.
645 root 1.1
646     Also add information on how to contact you by electronic and paper mail.
647    
648 root 1.2 If the program does terminal interaction, make it output a short
649 root 1.1 notice like this when it starts in an interactive mode:
650    
651 root 1.2 <program> Copyright (C) <year> <name of author>
652     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
653 root 1.1 This is free software, and you are welcome to redistribute it
654     under certain conditions; type `show c' for details.
655    
656 root 1.2 The hypothetical commands `show w' and `show c' should show the appropriate
657     parts of the General Public License. Of course, your program's commands
658     might be different; for a GUI interface, you would use an "about box".
659    
660     You should also get your employer (if you work as a programmer) or school,
661     if any, to sign a "copyright disclaimer" for the program, if necessary.
