1 root 1.12 Take note of the GNU Affero General Public License (COPYING.Affero),
2     which applies to part of this release, which means you have to follow the
3 root 1.14 requirements laid out in section 13 of both licenses (see COPYING.GNU).
4 root 1.12
5     As long as you follow the provisions of the APGL you should be safe.
6 root 1.4
7 root 1.13 Note that ALL changes introduced by the Deliantra team are under the
8 root 1.14 Affero General Public License. Specifically, the files listed below are
9     100% AGPL. The listing of these files does not imply the remaining files
10     do not contain any AGPL code (the opposite is actually true).
11 root 1.6
12 root 1.12 The archetypes and maps are mostly GPL, but all maps and archetype file
13     added by Deliantra are AGPL, unless otherwise noted (many media files are
14     cc:by or similarly permissive, and this is noted in the META.json files in
15     directories that have them). Again, note that unless you remove the AGPL
16     parts, then the whole server, maps and archetypes distributions have to be
17     treated according to the Affero GPL.
18    
19     Here is an algorithm to decide which parts of the server code are AGPL and
20     which are not:
21 root 1.9
22 root 1.10 1. is the file listed below (glob syntax)?
23     if yes, it is 100% AGPL.
24 root 1.9 2. does the file contain //+GPL and/or //-GPL markers?
25     if yes, then everything is AGPL, except the code between
26     //+GPL and //-GPL.
27     3. otherwise, the code is 100% GPL.

67 root 1.1
68 root 1.2 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
69 root 1.1 Everyone is permitted to copy and distribute verbatim copies
70     of this license document, but changing it is not allowed.
71    
72 root 1.2 Preamble
73 root 1.1
74     The GNU Affero General Public License is a free, copyleft license
75     for software and other kinds of works, specifically designed to ensure
76     cooperation with the community in the case of network server software.
77    
78     The licenses for most software and other practical works are
79     designed to take away your freedom to share and change the works. By
80     contrast, our General Public Licenses are intended to guarantee your
81     freedom to share and change all versions of a program--to make sure it
82     remains free software for all its users.
83    
84     When we speak of free software, we are referring to freedom, not
85     price. Our General Public Licenses are designed to make sure that you
86     have the freedom to distribute copies of free software (and charge for
87     them if you wish), that you receive source code or can get it if you
88     want it, that you can change the software or use pieces of it in new
89     free programs, and that you know you can do these things.
90    
91     Developers that use our General Public Licenses protect your rights
92     with two steps: (1) assert copyright on the software, and (2) offer
93     you this License which gives you legal permission to copy, distribute
94     and/or modify the software.
95    
96     A secondary benefit of defending all users' freedom is that
97     improvements made in alternate versions of the program, if they
98     receive widespread use, become available for other developers to
99     incorporate. Many developers of free software are heartened and
100     encouraged by the resulting cooperation. However, in the case of
101     software used on network servers, this result may fail to come about.
102     The GNU General Public License permits making a modified version and
103     letting the public access it on a server without ever releasing its
104     source code to the public.
105    
106     The GNU Affero General Public License is designed specifically to
107     ensure that, in such cases, the modified source code becomes available
108     to the community. It requires the operator of a network server to
109     provide the source code of the modified version running there to the
110     users of that server. Therefore, public use of a modified version, on
111     a publicly accessible server, gives the public access to the source
112     code of the modified version.
113    
114 root 1.3 An older license, called the Affero General Public License and
115     published by Affero, was designed to accomplish similar goals. This is
116     a different license, not a version of the Affero GPL, but Affero has
117     released a new version of the Affero GPL which permits relicensing under
118     this license.
119    
120 root 1.1 The precise terms and conditions for copying, distribution and
121     modification follow.
122    
123 root 1.2 TERMS AND CONDITIONS
124 root 1.1
125 root 1.2 0. Definitions.
126 root 1.1
127     "This License" refers to version 3 of the GNU Affero General Public
128     License.
129    
130 root 1.3 "Copyright" also means copyright-like laws that apply to other kinds
131     of works, such as semiconductor masks.
132    
133 root 1.1 "The Program" refers to any copyrightable work licensed under this
134 root 1.2 License. Each licensee is addressed as "you". "Licensees" and
135 root 1.1 "recipients" may be individuals or organizations.
136    
137 root 1.2 To "modify" a work means to copy from or adapt all or part of the work
138     in a fashion requiring copyright permission, other than the making of an
139     exact copy. The resulting work is called a "modified version" of the
140     earlier work or a work "based on" the earlier work.
141    
142     A "covered work" means either the unmodified Program or a work based
143     on the Program.
144 root 1.1
145     To "propagate" a work means to do anything with it that, without
146     permission, would make you directly or secondarily liable for
147     infringement under applicable copyright law, except executing it on a
148 root 1.2 computer or modifying a private copy. Propagation includes copying,
149     distribution (with or without modification), making available to the
150     public, and in some countries other activities as well.
151    
152     To "convey" a work means any kind of propagation that enables other
153     parties to make or receive copies. Mere interaction with a user through
154     a computer network, with no transfer of a copy, is not conveying.
155 root 1.1
156     An interactive user interface displays "Appropriate Legal Notices"
157     to the extent that it includes a convenient and prominently visible
158     feature that (1) displays an appropriate copyright notice, and (2)
159     tells the user that there is no warranty for the work (except to the
160     extent that warranties are provided), that licensees may convey the
161     work under this License, and how to view a copy of this License. If
162     the interface presents a list of user commands or options, such as a
163     menu, a prominent item in the list meets this criterion.
164    
165 root 1.2 1. Source Code.
166 root 1.1
167     The "source code" for a work means the preferred form of the work
168     for making modifications to it. "Object code" means any non-source
169     form of a work.
170    
171     A "Standard Interface" means an interface that either is an official
172     standard defined by a recognized standards body, or, in the case of
173     interfaces specified for a particular programming language, one that
174     is widely used among developers working in that language.
175    
176     The "System Libraries" of an executable work include anything, other
177     than the work as a whole, that (a) is included in the normal form of
178     packaging a Major Component, but which is not part of that Major
179     Component, and (b) serves only to enable use of the work with that
180     Major Component, or to implement a Standard Interface for which an
181     implementation is available to the public in source code form. A
182     "Major Component", in this context, means a major essential component
183     (kernel, window system, and so on) of the specific operating system
184     (if any) on which the executable work runs, or a compiler used to
185     produce the work, or an object code interpreter used to run it.
186    
187     The "Corresponding Source" for a work in object code form means all
188     the source code needed to generate, install, and (for an executable
189     work) run the object code and to modify the work, including scripts to
190     control those activities. However, it does not include the work's
191     System Libraries, or general-purpose tools or generally available free
192     programs which are used unmodified in performing those activities but
193     which are not part of the work. For example, Corresponding Source
194     includes interface definition files associated with source files for
195     the work, and the source code for shared libraries and dynamically
196     linked subprograms that the work is specifically designed to require,
197     such as by intimate data communication or control flow between those
198     subprograms and other parts of the work.
199    
200     The Corresponding Source need not include anything that users
201     can regenerate automatically from other parts of the Corresponding
202     Source.
203    
204     The Corresponding Source for a work in source code form is that
205     same work.
206    
207 root 1.2 2. Basic Permissions.
208 root 1.1
209     All rights granted under this License are granted for the term of
210     copyright on the Program, and are irrevocable provided the stated
211     conditions are met. This License explicitly affirms your unlimited
212     permission to run the unmodified Program. The output from running a
213     covered work is covered by this License only if the output, given its
214     content, constitutes a covered work. This License acknowledges your
215     rights of fair use or other equivalent, as provided by copyright law.
216    
217     You may make, run and propagate covered works that you do not
218     convey, without conditions so long as your license otherwise remains
219     in force. You may convey covered works to others for the sole purpose
220     of having them make modifications exclusively for you, or provide you
221     with facilities for running those works, provided that you comply with
222     the terms of this License in conveying all material for which you do
223 root 1.2 not control copyright. Those thus making or running the covered works
224 root 1.1 for you must do so exclusively on your behalf, under your direction
225     and control, on terms that prohibit them from making any copies of
226     your copyrighted material outside their relationship with you.
227    
228     Conveying under any other circumstances is permitted solely under
229     the conditions stated below. Sublicensing is not allowed; section 10
230     makes it unnecessary.
231    
232 root 1.2 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
233 root 1.1
234     No covered work shall be deemed part of an effective technological
235     measure under any applicable law fulfilling obligations under article
236     11 of the WIPO copyright treaty adopted on 20 December 1996, or
237     similar laws prohibiting or restricting circumvention of such
238     measures.
239    
240     When you convey a covered work, you waive any legal power to forbid
241 root 1.2 circumvention of technological measures to the extent such circumvention
242 root 1.1 is effected by exercising rights under this License with respect to
243     the covered work, and you disclaim any intention to limit operation or
244     modification of the work as a means of enforcing, against the work's
245     users, your or third parties' legal rights to forbid circumvention of
246 root 1.2 technological measures.
247 root 1.1
248 root 1.2 4. Conveying Verbatim Copies.
249 root 1.1
250     You may convey verbatim copies of the Program's source code as you
251     receive it, in any medium, provided that you conspicuously and
252     appropriately publish on each copy an appropriate copyright notice;
253     keep intact all notices stating that this License and any
254     non-permissive terms added in accord with section 7 apply to the code;
255     keep intact all notices of the absence of any warranty; and give all
256     recipients a copy of this License along with the Program.
257    
258     You may charge any price or no price for each copy that you convey,
259     and you may offer support or warranty protection for a fee.
260    
261 root 1.2 5. Conveying Modified Source Versions.
262 root 1.1
263     You may convey a work based on the Program, or the modifications to
264     produce it from the Program, in the form of source code under the
265 root 1.2 terms of section 4, provided that you also meet all of these conditions:
266 root 1.1
267     a) The work must carry prominent notices stating that you modified
268     it, and giving a relevant date.
269    
270     b) The work must carry prominent notices stating that it is
271     released under this License and any conditions added under section
272     7. This requirement modifies the requirement in section 4 to
273     "keep intact all notices".
274    
275     c) You must license the entire work, as a whole, under this
276     License to anyone who comes into possession of a copy. This
277     License will therefore apply, along with any applicable section 7
278     additional terms, to the whole of the work, and all its parts,
279     regardless of how they are packaged. This License gives no
280     permission to license the work in any other way, but it does not
281     invalidate such permission if you have separately received it.
282    
283     d) If the work has interactive user interfaces, each must display
284     Appropriate Legal Notices; however, if the Program has interactive
285     interfaces that do not display Appropriate Legal Notices, your
286     work need not make them do so.
287    
288 root 1.2 A compilation of a covered work with other separate and independent
289 root 1.1 works, which are not by their nature extensions of the covered work,
290 root 1.2 and which are not combined with it such as to form a larger program,
291 root 1.1 in or on a volume of a storage or distribution medium, is called an
292     "aggregate" if the compilation and its resulting copyright are not
293     used to limit the access or legal rights of the compilation's users
294     beyond what the individual works permit. Inclusion of a covered work
295     in an aggregate does not cause this License to apply to the other
296     parts of the aggregate.
297    
298 root 1.2 6. Conveying Non-Source Forms.
299 root 1.1
300 root 1.2 You may convey a covered work in object code form under the terms
301 root 1.1 of sections 4 and 5, provided that you also convey the
302     machine-readable Corresponding Source under the terms of this License,
303     in one of these ways:
304    
305     a) Convey the object code in, or embodied in, a physical product
306     (including a physical distribution medium), accompanied by the
307     Corresponding Source fixed on a durable physical medium
308     customarily used for software interchange.
309    
310     b) Convey the object code in, or embodied in, a physical product
311     (including a physical distribution medium), accompanied by a
312     written offer, valid for at least three years and valid for as
313     long as you offer spare parts or customer support for that product
314 root 1.2 model, to give anyone who possesses the object code either (1) a
315 root 1.1 copy of the Corresponding Source for all the software in the
316     product that is covered by this License, on a durable physical
317     medium customarily used for software interchange, for a price no
318     more than your reasonable cost of physically performing this
319 root 1.2 conveying of source, or (2) access to copy the
320 root 1.1 Corresponding Source from a network server at no charge.
321    
322     c) Convey individual copies of the object code with a copy of the
323     written offer to provide the Corresponding Source. This
324     alternative is allowed only occasionally and noncommercially, and
325     only if you received the object code with such an offer, in accord
326     with subsection 6b.
327    
328     d) Convey the object code by offering access from a designated
329     place (gratis or for a charge), and offer equivalent access to the
330     Corresponding Source in the same way through the same place at no
331     further charge. You need not require recipients to copy the
332 root 1.2 Corresponding Source along with the object code. If the place to
333 root 1.1 copy the object code is a network server, the Corresponding Source
334     may be on a different server (operated by you or a third party)
335     that supports equivalent copying facilities, provided you maintain
336     clear directions next to the object code saying where to find the
337 root 1.2 Corresponding Source. Regardless of what server hosts the
338 root 1.1 Corresponding Source, you remain obligated to ensure that it is
339     available for as long as needed to satisfy these requirements.
340    
341     e) Convey the object code using peer-to-peer transmission, provided
342     you inform other peers where the object code and Corresponding
343     Source of the work are being offered to the general public at no
344     charge under subsection 6d.
345    
346 root 1.2 A separable portion of the object code, whose source code is excluded
347 root 1.1 from the Corresponding Source as a System Library, need not be
348     included in conveying the object code work.
349    
350 root 1.2 A "User Product" is either (1) a "consumer product", which means any
351     tangible personal property which is normally used for personal, family,
352     or household purposes, or (2) anything designed or sold for incorporation
353     into a dwelling. In determining whether a product is a consumer product,
354     doubtful cases shall be resolved in favor of coverage. For a particular
355     product received by a particular user, "normally used" refers to a
356     typical or common use of that class of product, regardless of the status
357     of the particular user or of the way in which the particular user
358     actually uses, or expects or is expected to use, the product. A product
359     is a consumer product regardless of whether the product has substantial
360     commercial, industrial or non-consumer uses, unless such uses represent
361     the only significant mode of use of the product.
362    
363     "Installation Information" for a User Product means any methods,
364     procedures, authorization keys, or other information required to install
365     and execute modified versions of a covered work in that User Product from
366     a modified version of its Corresponding Source. The information must
367     suffice to ensure that the continued functioning of the modified object
368     code is in no case prevented or interfered with solely because
369     modification has been made.
370 root 1.1
371 root 1.2 If you convey an object code work under this section in, or with, or
372 root 1.1 specifically for use in, a User Product, and the conveying occurs as
373     part of a transaction in which the right of possession and use of the
374     User Product is transferred to the recipient in perpetuity or for a
375     fixed term (regardless of how the transaction is characterized), the
376     Corresponding Source conveyed under this section must be accompanied
377     by the Installation Information. But this requirement does not apply
378     if neither you nor any third party retains the ability to install
379     modified object code on the User Product (for example, the work has
380     been installed in ROM).
381    
382 root 1.2 The requirement to provide Installation Information does not include a
383     requirement to continue to provide support service, warranty, or updates
384     for a work that has been modified or installed by the recipient, or for
385     the User Product in which it has been modified or installed. Access to a
386     network may be denied when the modification itself materially and
387     adversely affects the operation of the network or violates the rules and
388     protocols for communication across the network.
389 root 1.1
390 root 1.2 Corresponding Source conveyed, and Installation Information provided,
391 root 1.1 in accord with this section must be in a format that is publicly
392     documented (and with an implementation available to the public in
393     source code form), and must require no special password or key for
394     unpacking, reading or copying.
395    
396 root 1.2 7. Additional Terms.
397 root 1.1
398     "Additional permissions" are terms that supplement the terms of this
399     License by making exceptions from one or more of its conditions.
400     Additional permissions that are applicable to the entire Program shall
401     be treated as though they were included in this License, to the extent
402     that they are valid under applicable law. If additional permissions
403     apply only to part of the Program, that part may be used separately
404     under those permissions, but the entire Program remains governed by
405     this License without regard to the additional permissions.
406    
407     When you convey a copy of a covered work, you may at your option
408     remove any additional permissions from that copy, or from any part of
409     it. (Additional permissions may be written to require their own
410     removal in certain cases when you modify the work.) You may place
411     additional permissions on material, added by you to a covered work,
412     for which you have or can give appropriate copyright permission.
413    
414 root 1.2 Notwithstanding any other provision of this License, for material you
415     add to a covered work, you may (if authorized by the copyright holders of
416     that material) supplement the terms of this License with terms:
417    
418     a) Disclaiming warranty or limiting liability differently from the
419     terms of sections 15 and 16 of this License; or
420    
421     b) Requiring preservation of specified reasonable legal notices or
422     author attributions in that material or in the Appropriate Legal
423     Notices displayed by works containing it; or
424    
425     c) Prohibiting misrepresentation of the origin of that material, or
426     requiring that modified versions of such material be marked in
427     reasonable ways as different from the original version; or
428    
429     d) Limiting the use for publicity purposes of names of licensors or
430     authors of the material; or
431    
432     e) Declining to grant rights under trademark law for use of some
433     trade names, trademarks, or service marks; or
434    
435     f) Requiring indemnification of licensors and authors of that
436     material by anyone who conveys the material (or modified versions of
437     it) with contractual assumptions of liability to the recipient, for
438     any liability that these contractual assumptions directly impose on
439     those licensors and authors.
440 root 1.1
441     All other non-permissive additional terms are considered "further
442     restrictions" within the meaning of section 10. If the Program as you
443 root 1.2 received it, or any part of it, contains a notice stating that it is
444 root 1.3 governed by this License along with a term that is a further restriction,
445     you may remove that term. If a license document contains a further
446     restriction but permits relicensing or conveying under this License, you
447     may add to a covered work material governed by the terms of that license
448     document, provided that the further restriction does not survive such
449     relicensing or conveying.
450 root 1.1
451     If you add terms to a covered work in accord with this section, you
452     must place, in the relevant source files, a statement of the
453     additional terms that apply to those files, or a notice indicating
454     where to find the applicable terms.
455    
456     Additional terms, permissive or non-permissive, may be stated in the
457     form of a separately written license, or stated as exceptions;
458     the above requirements apply either way.
459    
460 root 1.2 8. Termination.
461 root 1.1
462     You may not propagate or modify a covered work except as expressly
463     provided under this License. Any attempt otherwise to propagate or
464 root 1.2 modify it is void, and will automatically terminate your rights under
465     this License (including any patent licenses granted under the third
466     paragraph of section 11).
467    
468     However, if you cease all violation of this License, then your
469     license from a particular copyright holder is reinstated (a)
470     provisionally, unless and until the copyright holder explicitly and
471     finally terminates your license, and (b) permanently, if the copyright
472     holder fails to notify you of the violation by some reasonable means
473     prior to 60 days after the cessation.
474    
475     Moreover, your license from a particular copyright holder is
476     reinstated permanently if the copyright holder notifies you of the
477     violation by some reasonable means, this is the first time you have
478     received notice of violation of this License (for any work) from that
479     copyright holder, and you cure the violation prior to 30 days after
480     your receipt of the notice.
481    
482     Termination of your rights under this section does not terminate the
483     licenses of parties who have received copies or rights from you under
484     this License. If your rights have been terminated and not permanently
485     reinstated, you do not qualify to receive new licenses for the same
486     material under section 10.
487 root 1.1
488 root 1.2 9. Acceptance Not Required for Having Copies.
489 root 1.1
490     You are not required to accept this License in order to receive or
491     run a copy of the Program. Ancillary propagation of a covered work
492     occurring solely as a consequence of using peer-to-peer transmission
493     to receive a copy likewise does not require acceptance. However,
494     nothing other than this License grants you permission to propagate or
495     modify any covered work. These actions infringe copyright if you do
496     not accept this License. Therefore, by modifying or propagating a
497     covered work, you indicate your acceptance of this License to do so.
498    
499 root 1.2 10. Automatic Licensing of Downstream Recipients.
500 root 1.1
501     Each time you convey a covered work, the recipient automatically
502     receives a license from the original licensors, to run, modify and
503     propagate that work, subject to this License. You are not responsible
504     for enforcing compliance by third parties with this License.
505    
506     An "entity transaction" is a transaction transferring control of an
507     organization, or substantially all assets of one, or subdividing an
508     organization, or merging organizations. If propagation of a covered
509     work results from an entity transaction, each party to that
510     transaction who receives a copy of the work also receives whatever
511     licenses to the work the party's predecessor in interest had or could
512     give under the previous paragraph, plus a right to possession of the
513     Corresponding Source of the work from the predecessor in interest, if
514     the predecessor has it or can get it with reasonable efforts.
515    
516     You may not impose any further restrictions on the exercise of the
517     rights granted or affirmed under this License. For example, you may
518     not impose a license fee, royalty, or other charge for exercise of
519     rights granted under this License, and you may not initiate litigation
520     (including a cross-claim or counterclaim in a lawsuit) alleging that
521     any patent claim is infringed by making, using, selling, offering for
522     sale, or importing the Program or any portion of it.
523    
524     11. Patents.
525    
526     A "contributor" is a copyright holder who authorizes use under this
527     License of the Program or a work on which the Program is based. The
528 root 1.2 work thus licensed is called the contributor's "contributor version".
529 root 1.1
530     A contributor's "essential patent claims" are all patent claims
531     owned or controlled by the contributor, whether already acquired or
532     hereafter acquired, that would be infringed by some manner, permitted
533     by this License, of making, using, or selling its contributor version,
534     but do not include claims that would be infringed only as a
535     consequence of further modification of the contributor version. For
536     purposes of this definition, "control" includes the right to grant
537     patent sublicenses in a manner consistent with the requirements of
538     this License.
539    
540     Each contributor grants you a non-exclusive, worldwide, royalty-free
541     patent license under the contributor's essential patent claims, to
542     make, use, sell, offer for sale, import and otherwise run, modify and
543     propagate the contents of its contributor version.
544    
545 root 1.2 In the following three paragraphs, a "patent license" is any express
546     agreement or commitment, however denominated, not to enforce a patent
547     (such as an express permission to practice a patent or covenant not to
548     sue for patent infringement). To "grant" such a patent license to a
549     party means to make such an agreement or commitment not to enforce a
550     patent against the party.
551 root 1.1
552     If you convey a covered work, knowingly relying on a patent license,
553     and the Corresponding Source of the work is not available for anyone
554     to copy, free of charge and under the terms of this License, through a
555     publicly available network server or other readily accessible means,
556     then you must either (1) cause the Corresponding Source to be so
557 root 1.2 available, or (2) arrange to deprive yourself of the benefit of the
558     patent license for this particular work, or (3) arrange, in a manner
559     consistent with the requirements of this License, to extend the patent
560     license to downstream recipients. "Knowingly relying" means you have
561     actual knowledge that, but for the patent license, your conveying the
562     covered work in a country, or your recipient's use of the covered work
563     in a country, would infringe one or more identifiable patents in that
564     country that you have reason to believe are valid.
565    
566 root 1.1 If, pursuant to or in connection with a single transaction or
567     arrangement, you convey, or propagate by procuring conveyance of, a
568     covered work, and grant a patent license to some of the parties
569     receiving the covered work authorizing them to use, propagate, modify
570     or convey a specific copy of the covered work, then the patent license
571     you grant is automatically extended to all recipients of the covered
572     work and works based on it.
573    
574     A patent license is "discriminatory" if it does not include within
575     the scope of its coverage, prohibits the exercise of, or is
576     conditioned on the non-exercise of one or more of the rights that are
577     specifically granted under this License. You may not convey a covered
578     work if you are a party to an arrangement with a third party that is
579     in the business of distributing software, under which you make payment
580     to the third party based on the extent of your activity of conveying
581     the work, and under which the third party grants, to any of the
582     parties who would receive the covered work from you, a discriminatory
583     patent license (a) in connection with copies of the covered work
584     conveyed by you (or copies made from those copies), or (b) primarily
585     for and in connection with specific products or compilations that
586     contain the covered work, unless you entered into that arrangement,
587     or that patent license was granted, prior to 28 March 2007.
588    
589     Nothing in this License shall be construed as excluding or limiting
590     any implied license or other defenses to infringement that may
591     otherwise be available to you under applicable patent law.
592    
593 root 1.2 12. No Surrender of Others' Freedom.
594 root 1.1
595     If conditions are imposed on you (whether by court order, agreement or
596     otherwise) that contradict the conditions of this License, they do not
597 root 1.2 excuse you from the conditions of this License. If you cannot convey a
598     covered work so as to satisfy simultaneously your obligations under this
599     License and any other pertinent obligations, then as a consequence you may
600     not convey it at all. For example, if you agree to terms that obligate you
601     to collect a royalty for further conveying from those to whom you convey
602     the Program, the only way you could satisfy both those terms and this
603     License would be to refrain entirely from conveying the Program.
604 root 1.1
605     13. Remote Network Interaction; Use with the GNU General Public License.
606    
607 root 1.2 Notwithstanding any other provision of this License, if you modify the
608     Program, your modified version must prominently offer all users
609     interacting with it remotely through a computer network (if your version
610     supports such interaction) an opportunity to receive the Corresponding
611     Source of your version by providing access to the Corresponding Source
612     from a network server at no charge, through some standard or customary
613     means of facilitating copying of software. This Corresponding Source
614     shall include the Corresponding Source for any work covered by version 3
615     of the GNU General Public License that is incorporated pursuant to the
616     following paragraph.
617    
618     Notwithstanding any other provision of this License, you have permission
619     to link or combine any covered work with a work licensed under version 3
620     of the GNU General Public License into a single combined work, and to
621     convey the resulting work. The terms of this License will continue to
622     apply to the part which is the covered work, but the work with which it is
623     combined will remain governed by version 3 of the GNU General Public
624     License.
625    
626     14. Revised Versions of this License.
627    
628     The Free Software Foundation may publish revised and/or new versions of
629     the GNU Affero General Public License from time to time. Such new
630     versions will be similar in spirit to the present version, but may differ
631     in detail to address new problems or concerns.
632    
633 root 1.3 Each version is given a distinguishing version number. If the
634     Program specifies that a certain numbered version of the GNU Affero
635     General Public License "or any later version" applies to it, you have
636     the option of following the terms and conditions either of that
637     numbered version or of any later version published by the Free
638     Software Foundation. If the Program does not specify a version number
639     of the GNU Affero General Public License, you may choose any version
640     ever published by the Free Software Foundation.
641    
642     If the Program specifies that a proxy can decide which future
643     versions of the GNU Affero General Public License can be used, that
644     proxy's public statement of acceptance of a version permanently
645     authorizes you to choose that version for the Program.
646 root 1.1
647 root 1.2 Later license versions may give you additional or different
648 root 1.1 permissions. However, no additional obligations are imposed on any
649     author or copyright holder as a result of your choosing to follow a
650     later version.
651    
652 root 1.2 15. Disclaimer of Warranty.
653 root 1.1
654     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
655     APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
656     HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
657     OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
658     THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
659     PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
660     IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
661     ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
662    
663 root 1.2 16. Limitation of Liability.
664 root 1.1
665     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
666     WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
667     THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
668     GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
669     USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
670     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
671     PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
672     EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
673     SUCH DAMAGES.
674    
675     17. Interpretation of Sections 15 and 16.
676    
677     If the disclaimer of warranty and limitation of liability provided
678     above cannot be given local legal effect according to their terms,
679     reviewing courts shall apply local law that most closely approximates
680     an absolute waiver of all civil liability in connection with the
681     Program, unless a warranty or assumption of liability accompanies a
682     copy of the Program in return for a fee.
683    
684 root 1.3 END OF TERMS AND CONDITIONS
685 root 1.1
686 root 1.3 How to Apply These Terms to Your New Programs
687 root 1.1
688     If you develop a new program, and you want it to be of the greatest
689     possible use to the public, the best way to achieve this is to make it
690     free software which everyone can redistribute and change under these terms.
691    
692     To do so, attach the following notices to the program. It is safest
693     to attach them to the start of each source file to most effectively
694     state the exclusion of warranty; and each file should have at least
695     the "copyright" line and a pointer to where the full notice is found.
696    
697     <one line to give the program's name and a brief idea of what it does.>
698     Copyright (C) <year> <name of author>
699    
700 root 1.2 This program is free software: you can redistribute it and/or modify
701 root 1.3 it under the terms of the GNU Affero General Public License as
702     published by the Free Software Foundation, either version 3 of the
703     License, or (at your option) any later version.
704 root 1.1
705     This program is distributed in the hope that it will be useful,
706     but WITHOUT ANY WARRANTY; without even the implied warranty of
707     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
708     GNU Affero General Public License for more details.
709    
710     You should have received a copy of the GNU Affero General Public License
711 root 1.2 along with this program. If not, see <http://www.gnu.org/licenses/>.
712 root 1.1
713     Also add information on how to contact you by electronic and paper mail.
714    
715 root 1.3 If your software can interact with users remotely through a computer
716     network, you should also make sure that it provides a way for users to
717     get its source. For example, if your program is a web application, its
718     interface could display a "Source" link that leads users to an archive
719     of the code. There are many ways you could offer source, and different
720     solutions will be better for different programs; see section 13 for the
721     specific requirements.
722 root 1.2
723     You should also get your employer (if you work as a programmer) or school,
724     if any, to sign a "copyright disclaimer" for the program, if necessary.
