# Content
1 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 requirements laid out in section 13 of both licenses (see COPYING.GNU).
4
5 As long as you follow the provisions of the APGL you should be safe.
6
7 Note that ALL changes introduced by the Deliantra team are under the
8 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
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
22 1. is the file listed below (glob syntax)?
23 if yes, it is 100% AGPL.
24 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. is the code listed in COPYING.Other?
28 if yes, see there
29 4. otherwise, the code is 100% GPL.

71 GNU AFFERO GENERAL PUBLIC LICENSE
72 Version 3, 19 November 2007
73
74 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
75 Everyone is permitted to copy and distribute verbatim copies
76 of this license document, but changing it is not allowed.
77
78 Preamble
79
80 The GNU Affero General Public License is a free, copyleft license
81 for software and other kinds of works, specifically designed to ensure
82 cooperation with the community in the case of network server software.
83
84 The licenses for most software and other practical works are
85 designed to take away your freedom to share and change the works. By
86 contrast, our General Public Licenses are intended to guarantee your
87 freedom to share and change all versions of a program--to make sure it
88 remains free software for all its users.
89
90 When we speak of free software, we are referring to freedom, not
91 price. Our General Public Licenses are designed to make sure that you
92 have the freedom to distribute copies of free software (and charge for
93 them if you wish), that you receive source code or can get it if you
94 want it, that you can change the software or use pieces of it in new
95 free programs, and that you know you can do these things.
96
97 Developers that use our General Public Licenses protect your rights
98 with two steps: (1) assert copyright on the software, and (2) offer
99 you this License which gives you legal permission to copy, distribute
100 and/or modify the software.
101
102 A secondary benefit of defending all users' freedom is that
103 improvements made in alternate versions of the program, if they
104 receive widespread use, become available for other developers to
105 incorporate. Many developers of free software are heartened and
106 encouraged by the resulting cooperation. However, in the case of
107 software used on network servers, this result may fail to come about.
108 The GNU General Public License permits making a modified version and
109 letting the public access it on a server without ever releasing its
110 source code to the public.
111
112 The GNU Affero General Public License is designed specifically to
113 ensure that, in such cases, the modified source code becomes available
114 to the community. It requires the operator of a network server to
115 provide the source code of the modified version running there to the
116 users of that server. Therefore, public use of a modified version, on
117 a publicly accessible server, gives the public access to the source
118 code of the modified version.
119
120 An older license, called the Affero General Public License and
121 published by Affero, was designed to accomplish similar goals. This is
122 a different license, not a version of the Affero GPL, but Affero has
123 released a new version of the Affero GPL which permits relicensing under
124 this license.
125
126 The precise terms and conditions for copying, distribution and
127 modification follow.
128
129 TERMS AND CONDITIONS
130
131 0. Definitions.
132
133 "This License" refers to version 3 of the GNU Affero General Public
134 License.
135
136 "Copyright" also means copyright-like laws that apply to other kinds
137 of works, such as semiconductor masks.
138
139 "The Program" refers to any copyrightable work licensed under this
140 License. Each licensee is addressed as "you". "Licensees" and
141 "recipients" may be individuals or organizations.
142
143 To "modify" a work means to copy from or adapt all or part of the work
144 in a fashion requiring copyright permission, other than the making of an
145 exact copy. The resulting work is called a "modified version" of the
146 earlier work or a work "based on" the earlier work.
147
148 A "covered work" means either the unmodified Program or a work based
149 on the Program.
150
151 To "propagate" a work means to do anything with it that, without
152 permission, would make you directly or secondarily liable for
153 infringement under applicable copyright law, except executing it on a
154 computer or modifying a private copy. Propagation includes copying,
155 distribution (with or without modification), making available to the
156 public, and in some countries other activities as well.
157
158 To "convey" a work means any kind of propagation that enables other
159 parties to make or receive copies. Mere interaction with a user through
160 a computer network, with no transfer of a copy, is not conveying.
161
162 An interactive user interface displays "Appropriate Legal Notices"
163 to the extent that it includes a convenient and prominently visible
164 feature that (1) displays an appropriate copyright notice, and (2)
165 tells the user that there is no warranty for the work (except to the
166 extent that warranties are provided), that licensees may convey the
167 work under this License, and how to view a copy of this License. If
168 the interface presents a list of user commands or options, such as a
169 menu, a prominent item in the list meets this criterion.
170
171 1. Source Code.
172
173 The "source code" for a work means the preferred form of the work
174 for making modifications to it. "Object code" means any non-source
175 form of a work.
176
177 A "Standard Interface" means an interface that either is an official
178 standard defined by a recognized standards body, or, in the case of
179 interfaces specified for a particular programming language, one that
180 is widely used among developers working in that language.
181
182 The "System Libraries" of an executable work include anything, other
183 than the work as a whole, that (a) is included in the normal form of
184 packaging a Major Component, but which is not part of that Major
185 Component, and (b) serves only to enable use of the work with that
186 Major Component, or to implement a Standard Interface for which an
187 implementation is available to the public in source code form. A
188 "Major Component", in this context, means a major essential component
189 (kernel, window system, and so on) of the specific operating system
190 (if any) on which the executable work runs, or a compiler used to
191 produce the work, or an object code interpreter used to run it.
192
193 The "Corresponding Source" for a work in object code form means all
194 the source code needed to generate, install, and (for an executable
195 work) run the object code and to modify the work, including scripts to
196 control those activities. However, it does not include the work's
197 System Libraries, or general-purpose tools or generally available free
198 programs which are used unmodified in performing those activities but
199 which are not part of the work. For example, Corresponding Source
200 includes interface definition files associated with source files for
201 the work, and the source code for shared libraries and dynamically
202 linked subprograms that the work is specifically designed to require,
203 such as by intimate data communication or control flow between those
204 subprograms and other parts of the work.
205
206 The Corresponding Source need not include anything that users
207 can regenerate automatically from other parts of the Corresponding
208 Source.
209
210 The Corresponding Source for a work in source code form is that
211 same work.
212
213 2. Basic Permissions.
214
215 All rights granted under this License are granted for the term of
216 copyright on the Program, and are irrevocable provided the stated
217 conditions are met. This License explicitly affirms your unlimited
218 permission to run the unmodified Program. The output from running a
219 covered work is covered by this License only if the output, given its
220 content, constitutes a covered work. This License acknowledges your
221 rights of fair use or other equivalent, as provided by copyright law.
222
223 You may make, run and propagate covered works that you do not
224 convey, without conditions so long as your license otherwise remains
225 in force. You may convey covered works to others for the sole purpose
226 of having them make modifications exclusively for you, or provide you
227 with facilities for running those works, provided that you comply with
228 the terms of this License in conveying all material for which you do
229 not control copyright. Those thus making or running the covered works
230 for you must do so exclusively on your behalf, under your direction
231 and control, on terms that prohibit them from making any copies of
232 your copyrighted material outside their relationship with you.
233
234 Conveying under any other circumstances is permitted solely under
235 the conditions stated below. Sublicensing is not allowed; section 10
236 makes it unnecessary.
237
238 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
239
240 No covered work shall be deemed part of an effective technological
241 measure under any applicable law fulfilling obligations under article
242 11 of the WIPO copyright treaty adopted on 20 December 1996, or
243 similar laws prohibiting or restricting circumvention of such
244 measures.
245
246 When you convey a covered work, you waive any legal power to forbid
247 circumvention of technological measures to the extent such circumvention
248 is effected by exercising rights under this License with respect to
249 the covered work, and you disclaim any intention to limit operation or
250 modification of the work as a means of enforcing, against the work's
251 users, your or third parties' legal rights to forbid circumvention of
252 technological measures.
253
254 4. Conveying Verbatim Copies.
255
256 You may convey verbatim copies of the Program's source code as you
257 receive it, in any medium, provided that you conspicuously and
258 appropriately publish on each copy an appropriate copyright notice;
259 keep intact all notices stating that this License and any
260 non-permissive terms added in accord with section 7 apply to the code;
261 keep intact all notices of the absence of any warranty; and give all
262 recipients a copy of this License along with the Program.
263
264 You may charge any price or no price for each copy that you convey,
265 and you may offer support or warranty protection for a fee.
266
267 5. Conveying Modified Source Versions.
268
269 You may convey a work based on the Program, or the modifications to
270 produce it from the Program, in the form of source code under the
271 terms of section 4, provided that you also meet all of these conditions:
272
273 a) The work must carry prominent notices stating that you modified
274 it, and giving a relevant date.
275
276 b) The work must carry prominent notices stating that it is
277 released under this License and any conditions added under section
278 7. This requirement modifies the requirement in section 4 to
279 "keep intact all notices".
280
281 c) You must license the entire work, as a whole, under this
282 License to anyone who comes into possession of a copy. This
283 License will therefore apply, along with any applicable section 7
284 additional terms, to the whole of the work, and all its parts,
285 regardless of how they are packaged. This License gives no
286 permission to license the work in any other way, but it does not
287 invalidate such permission if you have separately received it.
288
289 d) If the work has interactive user interfaces, each must display
290 Appropriate Legal Notices; however, if the Program has interactive
291 interfaces that do not display Appropriate Legal Notices, your
292 work need not make them do so.
293
294 A compilation of a covered work with other separate and independent
295 works, which are not by their nature extensions of the covered work,
296 and which are not combined with it such as to form a larger program,
297 in or on a volume of a storage or distribution medium, is called an
298 "aggregate" if the compilation and its resulting copyright are not
299 used to limit the access or legal rights of the compilation's users
300 beyond what the individual works permit. Inclusion of a covered work
301 in an aggregate does not cause this License to apply to the other
302 parts of the aggregate.
303
304 6. Conveying Non-Source Forms.
305
306 You may convey a covered work in object code form under the terms
307 of sections 4 and 5, provided that you also convey the
308 machine-readable Corresponding Source under the terms of this License,
309 in one of these ways:
310
311 a) Convey the object code in, or embodied in, a physical product
312 (including a physical distribution medium), accompanied by the
313 Corresponding Source fixed on a durable physical medium
314 customarily used for software interchange.
315
316 b) Convey the object code in, or embodied in, a physical product
317 (including a physical distribution medium), accompanied by a
318 written offer, valid for at least three years and valid for as
319 long as you offer spare parts or customer support for that product
320 model, to give anyone who possesses the object code either (1) a
321 copy of the Corresponding Source for all the software in the
322 product that is covered by this License, on a durable physical
323 medium customarily used for software interchange, for a price no
324 more than your reasonable cost of physically performing this
325 conveying of source, or (2) access to copy the
326 Corresponding Source from a network server at no charge.
327
328 c) Convey individual copies of the object code with a copy of the
329 written offer to provide the Corresponding Source. This
330 alternative is allowed only occasionally and noncommercially, and
331 only if you received the object code with such an offer, in accord
332 with subsection 6b.
333
334 d) Convey the object code by offering access from a designated
335 place (gratis or for a charge), and offer equivalent access to the
336 Corresponding Source in the same way through the same place at no
337 further charge. You need not require recipients to copy the
338 Corresponding Source along with the object code. If the place to
339 copy the object code is a network server, the Corresponding Source
340 may be on a different server (operated by you or a third party)
341 that supports equivalent copying facilities, provided you maintain
342 clear directions next to the object code saying where to find the
343 Corresponding Source. Regardless of what server hosts the
344 Corresponding Source, you remain obligated to ensure that it is
345 available for as long as needed to satisfy these requirements.
346
347 e) Convey the object code using peer-to-peer transmission, provided
348 you inform other peers where the object code and Corresponding
349 Source of the work are being offered to the general public at no
350 charge under subsection 6d.
351
352 A separable portion of the object code, whose source code is excluded
353 from the Corresponding Source as a System Library, need not be
354 included in conveying the object code work.
355
356 A "User Product" is either (1) a "consumer product", which means any
357 tangible personal property which is normally used for personal, family,
358 or household purposes, or (2) anything designed or sold for incorporation
359 into a dwelling. In determining whether a product is a consumer product,
360 doubtful cases shall be resolved in favor of coverage. For a particular
361 product received by a particular user, "normally used" refers to a
362 typical or common use of that class of product, regardless of the status
363 of the particular user or of the way in which the particular user
364 actually uses, or expects or is expected to use, the product. A product
365 is a consumer product regardless of whether the product has substantial
366 commercial, industrial or non-consumer uses, unless such uses represent
367 the only significant mode of use of the product.
368
369 "Installation Information" for a User Product means any methods,
370 procedures, authorization keys, or other information required to install
371 and execute modified versions of a covered work in that User Product from
372 a modified version of its Corresponding Source. The information must
373 suffice to ensure that the continued functioning of the modified object
374 code is in no case prevented or interfered with solely because
375 modification has been made.
376
377 If you convey an object code work under this section in, or with, or
378 specifically for use in, a User Product, and the conveying occurs as
379 part of a transaction in which the right of possession and use of the
380 User Product is transferred to the recipient in perpetuity or for a
381 fixed term (regardless of how the transaction is characterized), the
382 Corresponding Source conveyed under this section must be accompanied
383 by the Installation Information. But this requirement does not apply
384 if neither you nor any third party retains the ability to install
385 modified object code on the User Product (for example, the work has
386 been installed in ROM).
387
388 The requirement to provide Installation Information does not include a
389 requirement to continue to provide support service, warranty, or updates
390 for a work that has been modified or installed by the recipient, or for
391 the User Product in which it has been modified or installed. Access to a
392 network may be denied when the modification itself materially and
393 adversely affects the operation of the network or violates the rules and
394 protocols for communication across the network.
395
396 Corresponding Source conveyed, and Installation Information provided,
397 in accord with this section must be in a format that is publicly
398 documented (and with an implementation available to the public in
399 source code form), and must require no special password or key for
400 unpacking, reading or copying.
401
402 7. Additional Terms.
403
404 "Additional permissions" are terms that supplement the terms of this
405 License by making exceptions from one or more of its conditions.
406 Additional permissions that are applicable to the entire Program shall
407 be treated as though they were included in this License, to the extent
408 that they are valid under applicable law. If additional permissions
409 apply only to part of the Program, that part may be used separately
410 under those permissions, but the entire Program remains governed by
411 this License without regard to the additional permissions.
412
413 When you convey a copy of a covered work, you may at your option
414 remove any additional permissions from that copy, or from any part of
415 it. (Additional permissions may be written to require their own
416 removal in certain cases when you modify the work.) You may place
417 additional permissions on material, added by you to a covered work,
418 for which you have or can give appropriate copyright permission.
419
420 Notwithstanding any other provision of this License, for material you
421 add to a covered work, you may (if authorized by the copyright holders of
422 that material) supplement the terms of this License with terms:
423
424 a) Disclaiming warranty or limiting liability differently from the
425 terms of sections 15 and 16 of this License; or
426
427 b) Requiring preservation of specified reasonable legal notices or
428 author attributions in that material or in the Appropriate Legal
429 Notices displayed by works containing it; or
430
431 c) Prohibiting misrepresentation of the origin of that material, or
432 requiring that modified versions of such material be marked in
433 reasonable ways as different from the original version; or
434
435 d) Limiting the use for publicity purposes of names of licensors or
436 authors of the material; or
437
438 e) Declining to grant rights under trademark law for use of some
439 trade names, trademarks, or service marks; or
440
441 f) Requiring indemnification of licensors and authors of that
442 material by anyone who conveys the material (or modified versions of
443 it) with contractual assumptions of liability to the recipient, for
444 any liability that these contractual assumptions directly impose on
445 those licensors and authors.
446
447 All other non-permissive additional terms are considered "further
448 restrictions" within the meaning of section 10. If the Program as you
449 received it, or any part of it, contains a notice stating that it is
450 governed by this License along with a term that is a further restriction,
451 you may remove that term. If a license document contains a further
452 restriction but permits relicensing or conveying under this License, you
453 may add to a covered work material governed by the terms of that license
454 document, provided that the further restriction does not survive such
455 relicensing or conveying.
456
457 If you add terms to a covered work in accord with this section, you
458 must place, in the relevant source files, a statement of the
459 additional terms that apply to those files, or a notice indicating
460 where to find the applicable terms.
461
462 Additional terms, permissive or non-permissive, may be stated in the
463 form of a separately written license, or stated as exceptions;
464 the above requirements apply either way.
465
466 8. Termination.
467
468 You may not propagate or modify a covered work except as expressly
469 provided under this License. Any attempt otherwise to propagate or
470 modify it is void, and will automatically terminate your rights under
471 this License (including any patent licenses granted under the third
472 paragraph of section 11).
473
474 However, if you cease all violation of this License, then your
475 license from a particular copyright holder is reinstated (a)
476 provisionally, unless and until the copyright holder explicitly and
477 finally terminates your license, and (b) permanently, if the copyright
478 holder fails to notify you of the violation by some reasonable means
479 prior to 60 days after the cessation.
480
481 Moreover, your license from a particular copyright holder is
482 reinstated permanently if the copyright holder notifies you of the
483 violation by some reasonable means, this is the first time you have
484 received notice of violation of this License (for any work) from that
485 copyright holder, and you cure the violation prior to 30 days after
486 your receipt of the notice.
487
488 Termination of your rights under this section does not terminate the
489 licenses of parties who have received copies or rights from you under
490 this License. If your rights have been terminated and not permanently
491 reinstated, you do not qualify to receive new licenses for the same
492 material under section 10.
493
494 9. Acceptance Not Required for Having Copies.
495
496 You are not required to accept this License in order to receive or
497 run a copy of the Program. Ancillary propagation of a covered work
498 occurring solely as a consequence of using peer-to-peer transmission
499 to receive a copy likewise does not require acceptance. However,
500 nothing other than this License grants you permission to propagate or
501 modify any covered work. These actions infringe copyright if you do
502 not accept this License. Therefore, by modifying or propagating a
503 covered work, you indicate your acceptance of this License to do so.
504
505 10. Automatic Licensing of Downstream Recipients.
506
507 Each time you convey a covered work, the recipient automatically
508 receives a license from the original licensors, to run, modify and
509 propagate that work, subject to this License. You are not responsible
510 for enforcing compliance by third parties with this License.
511
512 An "entity transaction" is a transaction transferring control of an
513 organization, or substantially all assets of one, or subdividing an
514 organization, or merging organizations. If propagation of a covered
515 work results from an entity transaction, each party to that
516 transaction who receives a copy of the work also receives whatever
517 licenses to the work the party's predecessor in interest had or could
518 give under the previous paragraph, plus a right to possession of the
519 Corresponding Source of the work from the predecessor in interest, if
520 the predecessor has it or can get it with reasonable efforts.
521
522 You may not impose any further restrictions on the exercise of the
523 rights granted or affirmed under this License. For example, you may
524 not impose a license fee, royalty, or other charge for exercise of
525 rights granted under this License, and you may not initiate litigation
526 (including a cross-claim or counterclaim in a lawsuit) alleging that
527 any patent claim is infringed by making, using, selling, offering for
528 sale, or importing the Program or any portion of it.
529
530 11. Patents.
531
532 A "contributor" is a copyright holder who authorizes use under this
533 License of the Program or a work on which the Program is based. The
534 work thus licensed is called the contributor's "contributor version".
535
536 A contributor's "essential patent claims" are all patent claims
537 owned or controlled by the contributor, whether already acquired or
538 hereafter acquired, that would be infringed by some manner, permitted
539 by this License, of making, using, or selling its contributor version,
540 but do not include claims that would be infringed only as a
541 consequence of further modification of the contributor version. For
542 purposes of this definition, "control" includes the right to grant
543 patent sublicenses in a manner consistent with the requirements of
544 this License.
545
546 Each contributor grants you a non-exclusive, worldwide, royalty-free
547 patent license under the contributor's essential patent claims, to
548 make, use, sell, offer for sale, import and otherwise run, modify and
549 propagate the contents of its contributor version.
550
551 In the following three paragraphs, a "patent license" is any express
552 agreement or commitment, however denominated, not to enforce a patent
553 (such as an express permission to practice a patent or covenant not to
554 sue for patent infringement). To "grant" such a patent license to a
555 party means to make such an agreement or commitment not to enforce a
556 patent against the party.
557
558 If you convey a covered work, knowingly relying on a patent license,
559 and the Corresponding Source of the work is not available for anyone
560 to copy, free of charge and under the terms of this License, through a
561 publicly available network server or other readily accessible means,
562 then you must either (1) cause the Corresponding Source to be so
563 available, or (2) arrange to deprive yourself of the benefit of the
564 patent license for this particular work, or (3) arrange, in a manner
565 consistent with the requirements of this License, to extend the patent
566 license to downstream recipients. "Knowingly relying" means you have
567 actual knowledge that, but for the patent license, your conveying the
568 covered work in a country, or your recipient's use of the covered work
569 in a country, would infringe one or more identifiable patents in that
570 country that you have reason to believe are valid.
571
572 If, pursuant to or in connection with a single transaction or
573 arrangement, you convey, or propagate by procuring conveyance of, a
574 covered work, and grant a patent license to some of the parties
575 receiving the covered work authorizing them to use, propagate, modify
576 or convey a specific copy of the covered work, then the patent license
577 you grant is automatically extended to all recipients of the covered
578 work and works based on it.
579
580 A patent license is "discriminatory" if it does not include within
581 the scope of its coverage, prohibits the exercise of, or is
582 conditioned on the non-exercise of one or more of the rights that are
583 specifically granted under this License. You may not convey a covered
584 work if you are a party to an arrangement with a third party that is
585 in the business of distributing software, under which you make payment
586 to the third party based on the extent of your activity of conveying
587 the work, and under which the third party grants, to any of the
588 parties who would receive the covered work from you, a discriminatory
589 patent license (a) in connection with copies of the covered work
590 conveyed by you (or copies made from those copies), or (b) primarily
591 for and in connection with specific products or compilations that
592 contain the covered work, unless you entered into that arrangement,
593 or that patent license was granted, prior to 28 March 2007.
594
595 Nothing in this License shall be construed as excluding or limiting
596 any implied license or other defenses to infringement that may
597 otherwise be available to you under applicable patent law.
598
599 12. No Surrender of Others' Freedom.
600
601 If conditions are imposed on you (whether by court order, agreement or
602 otherwise) that contradict the conditions of this License, they do not
603 excuse you from the conditions of this License. If you cannot convey a
604 covered work so as to satisfy simultaneously your obligations under this
605 License and any other pertinent obligations, then as a consequence you may
606 not convey it at all. For example, if you agree to terms that obligate you
607 to collect a royalty for further conveying from those to whom you convey
608 the Program, the only way you could satisfy both those terms and this
609 License would be to refrain entirely from conveying the Program.
610
611 13. Remote Network Interaction; Use with the GNU General Public License.
612
613 Notwithstanding any other provision of this License, if you modify the
614 Program, your modified version must prominently offer all users
615 interacting with it remotely through a computer network (if your version
616 supports such interaction) an opportunity to receive the Corresponding
617 Source of your version by providing access to the Corresponding Source
618 from a network server at no charge, through some standard or customary
619 means of facilitating copying of software. This Corresponding Source
620 shall include the Corresponding Source for any work covered by version 3
621 of the GNU General Public License that is incorporated pursuant to the
622 following paragraph.
623
624 Notwithstanding any other provision of this License, you have permission
625 to link or combine any covered work with a work licensed under version 3
626 of the GNU General Public License into a single combined work, and to
627 convey the resulting work. The terms of this License will continue to
628 apply to the part which is the covered work, but the work with which it is
629 combined will remain governed by version 3 of the GNU General Public
630 License.
631
632 14. Revised Versions of this License.
633
634 The Free Software Foundation may publish revised and/or new versions of
635 the GNU Affero General Public License from time to time. Such new
636 versions will be similar in spirit to the present version, but may differ
637 in detail to address new problems or concerns.
638
639 Each version is given a distinguishing version number. If the
640 Program specifies that a certain numbered version of the GNU Affero
641 General Public License "or any later version" applies to it, you have
642 the option of following the terms and conditions either of that
643 numbered version or of any later version published by the Free
644 Software Foundation. If the Program does not specify a version number
645 of the GNU Affero General Public License, you may choose any version
646 ever published by the Free Software Foundation.
647
648 If the Program specifies that a proxy can decide which future
649 versions of the GNU Affero General Public License can be used, that
650 proxy's public statement of acceptance of a version permanently
651 authorizes you to choose that version for the Program.
652
653 Later license versions may give you additional or different
654 permissions. However, no additional obligations are imposed on any
655 author or copyright holder as a result of your choosing to follow a
656 later version.
657
658 15. Disclaimer of Warranty.
659
660 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
661 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
662 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
663 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
664 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
665 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
666 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
667 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
668
669 16. Limitation of Liability.
670
671 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
672 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
673 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
674 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
675 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
676 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
677 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
678 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
679 SUCH DAMAGES.
680
681 17. Interpretation of Sections 15 and 16.
682
683 If the disclaimer of warranty and limitation of liability provided
684 above cannot be given local legal effect according to their terms,
685 reviewing courts shall apply local law that most closely approximates
686 an absolute waiver of all civil liability in connection with the
687 Program, unless a warranty or assumption of liability accompanies a
688 copy of the Program in return for a fee.
689
690 END OF TERMS AND CONDITIONS
691
692 How to Apply These Terms to Your New Programs
693
694 If you develop a new program, and you want it to be of the greatest
695 possible use to the public, the best way to achieve this is to make it
696 free software which everyone can redistribute and change under these terms.
697
698 To do so, attach the following notices to the program. It is safest
699 to attach them to the start of each source file to most effectively
700 state the exclusion of warranty; and each file should have at least
701 the "copyright" line and a pointer to where the full notice is found.
702
703 <one line to give the program's name and a brief idea of what it does.>
704 Copyright (C) <year> <name of author>
705
706 This program is free software: you can redistribute it and/or modify
707 it under the terms of the GNU Affero General Public License as
708 published by the Free Software Foundation, either version 3 of the
709 License, or (at your option) any later version.
710
711 This program is distributed in the hope that it will be useful,
712 but WITHOUT ANY WARRANTY; without even the implied warranty of
713 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
714 GNU Affero General Public License for more details.
715
716 You should have received a copy of the GNU Affero General Public License
717 along with this program. If not, see <http://www.gnu.org/licenses/>.
718
719 Also add information on how to contact you by electronic and paper mail.
720
721 If your software can interact with users remotely through a computer
722 network, you should also make sure that it provides a way for users to
723 get its source. For example, if your program is a web application, its
724 interface could display a "Source" link that leads users to an archive
725 of the code. There are many ways you could offer source, and different
726 solutions will be better for different programs; see section 13 for the
727 specific requirements.
728
729 You should also get your employer (if you work as a programmer) or school,
730 if any, to sign a "copyright disclaimer" for the program, if necessary.
