5 root 1.7 Note that ALL changes introduced by the Deliantra team are under the
6 root 1.8 Affero General Public License, but the files that are fully AGPL are
7 root 1.5 documented inside COPYING.Affero, as well as which parts of the remaining
8     files, for your convinience. Those files comprise a substantial part
9     of the runtime system, and as long as you don't remove them, your
10     installation will have to follow the AGPL license.

15     GNU GENERAL PUBLIC LICENSE
16     Version 3, 29 June 2007
17    
18     Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
19     Everyone is permitted to copy and distribute verbatim copies
20     of this license document, but changing it is not allowed.
21    
22     Preamble
23    
24     The GNU General Public License is a free, copyleft license for
25     software and other kinds of works.
26    
27     The licenses for most software and other practical works are designed
28     to take away your freedom to share and change the works. By contrast,
29     the GNU General Public License is intended to guarantee your freedom to
30     share and change all versions of a program--to make sure it remains free
31     software for all its users. We, the Free Software Foundation, use the
32     GNU General Public License for most of our software; it applies also to
33     any other work released this way by its authors. You can apply it to
34     your programs, too.
35    
36     When we speak of free software, we are referring to freedom, not
37     price. Our General Public Licenses are designed to make sure that you
38     have the freedom to distribute copies of free software (and charge for
39     them if you wish), that you receive source code or can get it if you
40     want it, that you can change the software or use pieces of it in new
41     free programs, and that you know you can do these things.
42    
43     To protect your rights, we need to prevent others from denying you
44     these rights or asking you to surrender the rights. Therefore, you have
45     certain responsibilities if you distribute copies of the software, or if
46     you modify it: responsibilities to respect the freedom of others.
47    
48     For example, if you distribute copies of such a program, whether
49     gratis or for a fee, you must pass on to the recipients the same
50     freedoms that you received. You must make sure that they, too, receive
51     or can get the source code. And you must show them these terms so they
52     know their rights.
53    
54     Developers that use the GNU GPL protect your rights with two steps:
55     (1) assert copyright on the software, and (2) offer you this License
56     giving you legal permission to copy, distribute and/or modify it.
57    
58     For the developers' and authors' protection, the GPL clearly explains
59     that there is no warranty for this free software. For both users' and
60     authors' sake, the GPL requires that modified versions be marked as
61     changed, so that their problems will not be attributed erroneously to
62     authors of previous versions.
63    
64     Some devices are designed to deny users access to install or run
65     modified versions of the software inside them, although the manufacturer
66     can do so. This is fundamentally incompatible with the aim of
67     protecting users' freedom to change the software. The systematic
68     pattern of such abuse occurs in the area of products for individuals to
69     use, which is precisely where it is most unacceptable. Therefore, we
70     have designed this version of the GPL to prohibit the practice for those
71     products. If such problems arise substantially in other domains, we
72     stand ready to extend this provision to those domains in future versions
73     of the GPL, as needed to protect the freedom of users.
74    
75     Finally, every program is threatened constantly by software patents.
76     States should not allow patents to restrict development and use of
77     software on general-purpose computers, but in those that do, we wish to
78     avoid the special danger that patents applied to a free program could
79     make it effectively proprietary. To prevent this, the GPL assures that
80     patents cannot be used to render the program non-free.
81    
82     The precise terms and conditions for copying, distribution and
83     modification follow.
84    
85     TERMS AND CONDITIONS
86    
87     0. Definitions.
88    
89     "This License" refers to version 3 of the GNU General Public License.
90    
91     "Copyright" also means copyright-like laws that apply to other kinds of
92     works, such as semiconductor masks.
93    
94     "The Program" refers to any copyrightable work licensed under this
95     License. Each licensee is addressed as "you". "Licensees" and
96     "recipients" may be individuals or organizations.
97    
98     To "modify" a work means to copy from or adapt all or part of the work
99     in a fashion requiring copyright permission, other than the making of an
100     exact copy. The resulting work is called a "modified version" of the
101     earlier work or a work "based on" the earlier work.
102    
103     A "covered work" means either the unmodified Program or a work based
104     on the Program.
105    
106     To "propagate" a work means to do anything with it that, without
107     permission, would make you directly or secondarily liable for
108     infringement under applicable copyright law, except executing it on a
109     computer or modifying a private copy. Propagation includes copying,
110     distribution (with or without modification), making available to the
111     public, and in some countries other activities as well.
112    
113     To "convey" a work means any kind of propagation that enables other
114     parties to make or receive copies. Mere interaction with a user through
115     a computer network, with no transfer of a copy, is not conveying.
116    
117     An interactive user interface displays "Appropriate Legal Notices"
118     to the extent that it includes a convenient and prominently visible
119     feature that (1) displays an appropriate copyright notice, and (2)
120     tells the user that there is no warranty for the work (except to the
121     extent that warranties are provided), that licensees may convey the
122     work under this License, and how to view a copy of this License. If
123     the interface presents a list of user commands or options, such as a
124     menu, a prominent item in the list meets this criterion.
125    
126     1. Source Code.
127    
128     The "source code" for a work means the preferred form of the work
129     for making modifications to it. "Object code" means any non-source
130     form of a work.
131    
132     A "Standard Interface" means an interface that either is an official
133     standard defined by a recognized standards body, or, in the case of
134     interfaces specified for a particular programming language, one that
135     is widely used among developers working in that language.
136    
137     The "System Libraries" of an executable work include anything, other
138     than the work as a whole, that (a) is included in the normal form of
139     packaging a Major Component, but which is not part of that Major
140     Component, and (b) serves only to enable use of the work with that
141     Major Component, or to implement a Standard Interface for which an
142     implementation is available to the public in source code form. A
143     "Major Component", in this context, means a major essential component
144     (kernel, window system, and so on) of the specific operating system
145     (if any) on which the executable work runs, or a compiler used to
146     produce the work, or an object code interpreter used to run it.
147    
148     The "Corresponding Source" for a work in object code form means all
149     the source code needed to generate, install, and (for an executable
150     work) run the object code and to modify the work, including scripts to
151     control those activities. However, it does not include the work's
152     System Libraries, or general-purpose tools or generally available free
153     programs which are used unmodified in performing those activities but
154     which are not part of the work. For example, Corresponding Source
155     includes interface definition files associated with source files for
156     the work, and the source code for shared libraries and dynamically
157     linked subprograms that the work is specifically designed to require,
158     such as by intimate data communication or control flow between those
159     subprograms and other parts of the work.
160    
161     The Corresponding Source need not include anything that users
162     can regenerate automatically from other parts of the Corresponding
163     Source.
164    
165     The Corresponding Source for a work in source code form is that
166     same work.
167    
168     2. Basic Permissions.
169    
170     All rights granted under this License are granted for the term of
171     copyright on the Program, and are irrevocable provided the stated
172     conditions are met. This License explicitly affirms your unlimited
173     permission to run the unmodified Program. The output from running a
174     covered work is covered by this License only if the output, given its
175     content, constitutes a covered work. This License acknowledges your
176     rights of fair use or other equivalent, as provided by copyright law.
177    
178     You may make, run and propagate covered works that you do not
179     convey, without conditions so long as your license otherwise remains
180     in force. You may convey covered works to others for the sole purpose
181     of having them make modifications exclusively for you, or provide you
182     with facilities for running those works, provided that you comply with
183     the terms of this License in conveying all material for which you do
184     not control copyright. Those thus making or running the covered works
185     for you must do so exclusively on your behalf, under your direction
186     and control, on terms that prohibit them from making any copies of
187     your copyrighted material outside their relationship with you.
188    
189     Conveying under any other circumstances is permitted solely under
190     the conditions stated below. Sublicensing is not allowed; section 10
191     makes it unnecessary.
192    
193     3. Protecting Users' Legal Rights From Anti-Circumvention Law.
194    
195     No covered work shall be deemed part of an effective technological
196     measure under any applicable law fulfilling obligations under article
197     11 of the WIPO copyright treaty adopted on 20 December 1996, or
198     similar laws prohibiting or restricting circumvention of such
199     measures.
200    
201     When you convey a covered work, you waive any legal power to forbid
202     circumvention of technological measures to the extent such circumvention
203     is effected by exercising rights under this License with respect to
204     the covered work, and you disclaim any intention to limit operation or
205     modification of the work as a means of enforcing, against the work's
206     users, your or third parties' legal rights to forbid circumvention of
207     technological measures.
208    
209     4. Conveying Verbatim Copies.
210    
211     You may convey verbatim copies of the Program's source code as you
212     receive it, in any medium, provided that you conspicuously and
213     appropriately publish on each copy an appropriate copyright notice;
214     keep intact all notices stating that this License and any
215     non-permissive terms added in accord with section 7 apply to the code;
216     keep intact all notices of the absence of any warranty; and give all
217     recipients a copy of this License along with the Program.
218    
219     You may charge any price or no price for each copy that you convey,
220     and you may offer support or warranty protection for a fee.
221    
222     5. Conveying Modified Source Versions.
223    
224     You may convey a work based on the Program, or the modifications to
225     produce it from the Program, in the form of source code under the
226     terms of section 4, provided that you also meet all of these conditions:
227    
228     a) The work must carry prominent notices stating that you modified
229     it, and giving a relevant date.
230    
231     b) The work must carry prominent notices stating that it is
232     released under this License and any conditions added under section
233     7. This requirement modifies the requirement in section 4 to
234     "keep intact all notices".
235    
236     c) You must license the entire work, as a whole, under this
237     License to anyone who comes into possession of a copy. This
238     License will therefore apply, along with any applicable section 7
239     additional terms, to the whole of the work, and all its parts,
240     regardless of how they are packaged. This License gives no
241     permission to license the work in any other way, but it does not
242     invalidate such permission if you have separately received it.
243    
244     d) If the work has interactive user interfaces, each must display
245     Appropriate Legal Notices; however, if the Program has interactive
246     interfaces that do not display Appropriate Legal Notices, your
247     work need not make them do so.
248    
249     A compilation of a covered work with other separate and independent
250     works, which are not by their nature extensions of the covered work,
251     and which are not combined with it such as to form a larger program,
252     in or on a volume of a storage or distribution medium, is called an
253     "aggregate" if the compilation and its resulting copyright are not
254     used to limit the access or legal rights of the compilation's users
255     beyond what the individual works permit. Inclusion of a covered work
256     in an aggregate does not cause this License to apply to the other
257     parts of the aggregate.
258    
259     6. Conveying Non-Source Forms.
260    
261     You may convey a covered work in object code form under the terms
262     of sections 4 and 5, provided that you also convey the
263     machine-readable Corresponding Source under the terms of this License,
264     in one of these ways:
265    
266     a) Convey the object code in, or embodied in, a physical product
267     (including a physical distribution medium), accompanied by the
268     Corresponding Source fixed on a durable physical medium
269     customarily used for software interchange.
270    
271     b) Convey the object code in, or embodied in, a physical product
272     (including a physical distribution medium), accompanied by a
273     written offer, valid for at least three years and valid for as
274     long as you offer spare parts or customer support for that product
275     model, to give anyone who possesses the object code either (1) a
276     copy of the Corresponding Source for all the software in the
277     product that is covered by this License, on a durable physical
278     medium customarily used for software interchange, for a price no
279     more than your reasonable cost of physically performing this
280     conveying of source, or (2) access to copy the
281     Corresponding Source from a network server at no charge.
282    
283     c) Convey individual copies of the object code with a copy of the
284     written offer to provide the Corresponding Source. This
285     alternative is allowed only occasionally and noncommercially, and
286     only if you received the object code with such an offer, in accord
287     with subsection 6b.
288    
289     d) Convey the object code by offering access from a designated
290     place (gratis or for a charge), and offer equivalent access to the
291     Corresponding Source in the same way through the same place at no
292     further charge. You need not require recipients to copy the
293     Corresponding Source along with the object code. If the place to
294     copy the object code is a network server, the Corresponding Source
295     may be on a different server (operated by you or a third party)
296     that supports equivalent copying facilities, provided you maintain
297     clear directions next to the object code saying where to find the
298     Corresponding Source. Regardless of what server hosts the
299     Corresponding Source, you remain obligated to ensure that it is
300     available for as long as needed to satisfy these requirements.
301    
302     e) Convey the object code using peer-to-peer transmission, provided
303     you inform other peers where the object code and Corresponding
304     Source of the work are being offered to the general public at no
305     charge under subsection 6d.
306    
307     A separable portion of the object code, whose source code is excluded
308     from the Corresponding Source as a System Library, need not be
309     included in conveying the object code work.
310    
311     A "User Product" is either (1) a "consumer product", which means any
312     tangible personal property which is normally used for personal, family,
313     or household purposes, or (2) anything designed or sold for incorporation
314     into a dwelling. In determining whether a product is a consumer product,
315     doubtful cases shall be resolved in favor of coverage. For a particular
316     product received by a particular user, "normally used" refers to a
317     typical or common use of that class of product, regardless of the status
318     of the particular user or of the way in which the particular user
319     actually uses, or expects or is expected to use, the product. A product
320     is a consumer product regardless of whether the product has substantial
321     commercial, industrial or non-consumer uses, unless such uses represent
322     the only significant mode of use of the product.
323    
324     "Installation Information" for a User Product means any methods,
325     procedures, authorization keys, or other information required to install
326     and execute modified versions of a covered work in that User Product from
327     a modified version of its Corresponding Source. The information must
328     suffice to ensure that the continued functioning of the modified object
329     code is in no case prevented or interfered with solely because
330     modification has been made.
331    
332     If you convey an object code work under this section in, or with, or
333     specifically for use in, a User Product, and the conveying occurs as
334     part of a transaction in which the right of possession and use of the
335     User Product is transferred to the recipient in perpetuity or for a
336     fixed term (regardless of how the transaction is characterized), the
337     Corresponding Source conveyed under this section must be accompanied
338     by the Installation Information. But this requirement does not apply
339     if neither you nor any third party retains the ability to install
340     modified object code on the User Product (for example, the work has
341     been installed in ROM).
342    
343     The requirement to provide Installation Information does not include a
344     requirement to continue to provide support service, warranty, or updates
345     for a work that has been modified or installed by the recipient, or for
346     the User Product in which it has been modified or installed. Access to a
347     network may be denied when the modification itself materially and
348     adversely affects the operation of the network or violates the rules and
349     protocols for communication across the network.
350    
351     Corresponding Source conveyed, and Installation Information provided,
352     in accord with this section must be in a format that is publicly
353     documented (and with an implementation available to the public in
354     source code form), and must require no special password or key for
355     unpacking, reading or copying.
356    
357     7. Additional Terms.
358    
359     "Additional permissions" are terms that supplement the terms of this
360     License by making exceptions from one or more of its conditions.
361     Additional permissions that are applicable to the entire Program shall
362     be treated as though they were included in this License, to the extent
363     that they are valid under applicable law. If additional permissions
364     apply only to part of the Program, that part may be used separately
365     under those permissions, but the entire Program remains governed by
366     this License without regard to the additional permissions.
367    
368     When you convey a copy of a covered work, you may at your option
369     remove any additional permissions from that copy, or from any part of
370     it. (Additional permissions may be written to require their own
371     removal in certain cases when you modify the work.) You may place
372     additional permissions on material, added by you to a covered work,
373     for which you have or can give appropriate copyright permission.
374    
375     Notwithstanding any other provision of this License, for material you
376     add to a covered work, you may (if authorized by the copyright holders of
377     that material) supplement the terms of this License with terms:
378    
379     a) Disclaiming warranty or limiting liability differently from the
380     terms of sections 15 and 16 of this License; or
381    
382     b) Requiring preservation of specified reasonable legal notices or
383     author attributions in that material or in the Appropriate Legal
384     Notices displayed by works containing it; or
385    
386     c) Prohibiting misrepresentation of the origin of that material, or
387     requiring that modified versions of such material be marked in
388     reasonable ways as different from the original version; or
389    
390     d) Limiting the use for publicity purposes of names of licensors or
391     authors of the material; or
392    
393     e) Declining to grant rights under trademark law for use of some
394     trade names, trademarks, or service marks; or
395    
396     f) Requiring indemnification of licensors and authors of that
397     material by anyone who conveys the material (or modified versions of
398     it) with contractual assumptions of liability to the recipient, for
399     any liability that these contractual assumptions directly impose on
400     those licensors and authors.
401    
402     All other non-permissive additional terms are considered "further
403     restrictions" within the meaning of section 10. If the Program as you
404     received it, or any part of it, contains a notice stating that it is
405     governed by this License along with a term that is a further
406     restriction, you may remove that term. If a license document contains
407     a further restriction but permits relicensing or conveying under this
408     License, you may add to a covered work material governed by the terms
409     of that license document, provided that the further restriction does
410     not survive such relicensing or conveying.
411    
412     If you add terms to a covered work in accord with this section, you
413     must place, in the relevant source files, a statement of the
414     additional terms that apply to those files, or a notice indicating
415     where to find the applicable terms.
416    
417     Additional terms, permissive or non-permissive, may be stated in the
418     form of a separately written license, or stated as exceptions;
419     the above requirements apply either way.
420    
421     8. Termination.
422    
423     You may not propagate or modify a covered work except as expressly
424     provided under this License. Any attempt otherwise to propagate or
425     modify it is void, and will automatically terminate your rights under
426     this License (including any patent licenses granted under the third
427     paragraph of section 11).
428    
429     However, if you cease all violation of this License, then your
430     license from a particular copyright holder is reinstated (a)
431     provisionally, unless and until the copyright holder explicitly and
432     finally terminates your license, and (b) permanently, if the copyright
433     holder fails to notify you of the violation by some reasonable means
434     prior to 60 days after the cessation.
435    
436     Moreover, your license from a particular copyright holder is
437     reinstated permanently if the copyright holder notifies you of the
438     violation by some reasonable means, this is the first time you have
439     received notice of violation of this License (for any work) from that
440     copyright holder, and you cure the violation prior to 30 days after
441     your receipt of the notice.
442    
443     Termination of your rights under this section does not terminate the
444     licenses of parties who have received copies or rights from you under
445     this License. If your rights have been terminated and not permanently
446     reinstated, you do not qualify to receive new licenses for the same
447     material under section 10.
448    
449     9. Acceptance Not Required for Having Copies.
450    
451     You are not required to accept this License in order to receive or
452     run a copy of the Program. Ancillary propagation of a covered work
453     occurring solely as a consequence of using peer-to-peer transmission
454     to receive a copy likewise does not require acceptance. However,
455     nothing other than this License grants you permission to propagate or
456     modify any covered work. These actions infringe copyright if you do
457     not accept this License. Therefore, by modifying or propagating a
458     covered work, you indicate your acceptance of this License to do so.
459    
460     10. Automatic Licensing of Downstream Recipients.
461    
462     Each time you convey a covered work, the recipient automatically
463     receives a license from the original licensors, to run, modify and
464     propagate that work, subject to this License. You are not responsible
465     for enforcing compliance by third parties with this License.
466    
467     An "entity transaction" is a transaction transferring control of an
468     organization, or substantially all assets of one, or subdividing an
469     organization, or merging organizations. If propagation of a covered
470     work results from an entity transaction, each party to that
471     transaction who receives a copy of the work also receives whatever
472     licenses to the work the party's predecessor in interest had or could
473     give under the previous paragraph, plus a right to possession of the
474     Corresponding Source of the work from the predecessor in interest, if
475     the predecessor has it or can get it with reasonable efforts.
476    
477     You may not impose any further restrictions on the exercise of the
478     rights granted or affirmed under this License. For example, you may
479     not impose a license fee, royalty, or other charge for exercise of
480     rights granted under this License, and you may not initiate litigation
481     (including a cross-claim or counterclaim in a lawsuit) alleging that
482     any patent claim is infringed by making, using, selling, offering for
483     sale, or importing the Program or any portion of it.
484    
485     11. Patents.
486    
487     A "contributor" is a copyright holder who authorizes use under this
488     License of the Program or a work on which the Program is based. The
489     work thus licensed is called the contributor's "contributor version".
490    
491     A contributor's "essential patent claims" are all patent claims
492     owned or controlled by the contributor, whether already acquired or
493     hereafter acquired, that would be infringed by some manner, permitted
494     by this License, of making, using, or selling its contributor version,
495     but do not include claims that would be infringed only as a
496     consequence of further modification of the contributor version. For
497     purposes of this definition, "control" includes the right to grant
498     patent sublicenses in a manner consistent with the requirements of
499     this License.
500    
501     Each contributor grants you a non-exclusive, worldwide, royalty-free
502     patent license under the contributor's essential patent claims, to
503     make, use, sell, offer for sale, import and otherwise run, modify and
504     propagate the contents of its contributor version.
505    
506     In the following three paragraphs, a "patent license" is any express
507     agreement or commitment, however denominated, not to enforce a patent
508     (such as an express permission to practice a patent or covenant not to
509     sue for patent infringement). To "grant" such a patent license to a
510     party means to make such an agreement or commitment not to enforce a
511     patent against the party.
512    
513     If you convey a covered work, knowingly relying on a patent license,
514     and the Corresponding Source of the work is not available for anyone
515     to copy, free of charge and under the terms of this License, through a
516     publicly available network server or other readily accessible means,
517     then you must either (1) cause the Corresponding Source to be so
518     available, or (2) arrange to deprive yourself of the benefit of the
519     patent license for this particular work, or (3) arrange, in a manner
520     consistent with the requirements of this License, to extend the patent
521     license to downstream recipients. "Knowingly relying" means you have
522     actual knowledge that, but for the patent license, your conveying the
523     covered work in a country, or your recipient's use of the covered work
524     in a country, would infringe one or more identifiable patents in that
525     country that you have reason to believe are valid.
526    
527     If, pursuant to or in connection with a single transaction or
528     arrangement, you convey, or propagate by procuring conveyance of, a
529     covered work, and grant a patent license to some of the parties
530     receiving the covered work authorizing them to use, propagate, modify
531     or convey a specific copy of the covered work, then the patent license
532     you grant is automatically extended to all recipients of the covered
533     work and works based on it.
534    
535     A patent license is "discriminatory" if it does not include within
536     the scope of its coverage, prohibits the exercise of, or is
537     conditioned on the non-exercise of one or more of the rights that are
538     specifically granted under this License. You may not convey a covered
539     work if you are a party to an arrangement with a third party that is
540     in the business of distributing software, under which you make payment
541     to the third party based on the extent of your activity of conveying
542     the work, and under which the third party grants, to any of the
543     parties who would receive the covered work from you, a discriminatory
544     patent license (a) in connection with copies of the covered work
545     conveyed by you (or copies made from those copies), or (b) primarily
546     for and in connection with specific products or compilations that
547     contain the covered work, unless you entered into that arrangement,
548     or that patent license was granted, prior to 28 March 2007.
549    
550     Nothing in this License shall be construed as excluding or limiting
551     any implied license or other defenses to infringement that may
552     otherwise be available to you under applicable patent law.
553    
554     12. No Surrender of Others' Freedom.
555    
556     If conditions are imposed on you (whether by court order, agreement or
557     otherwise) that contradict the conditions of this License, they do not
558     excuse you from the conditions of this License. If you cannot convey a
559     covered work so as to satisfy simultaneously your obligations under this
560     License and any other pertinent obligations, then as a consequence you may
561     not convey it at all. For example, if you agree to terms that obligate you
562     to collect a royalty for further conveying from those to whom you convey
563     the Program, the only way you could satisfy both those terms and this
564     License would be to refrain entirely from conveying the Program.
565    
566     13. Use with the GNU Affero General Public License.
567    
568     Notwithstanding any other provision of this License, you have
569     permission to link or combine any covered work with a work licensed
570     under version 3 of the GNU Affero General Public License into a single
571     combined work, and to convey the resulting work. The terms of this
572     License will continue to apply to the part which is the covered work,
573     but the special requirements of the GNU Affero General Public License,
574     section 13, concerning interaction through a network will apply to the
575     combination as such.
576    
577     14. Revised Versions of this License.
578    
579     The Free Software Foundation may publish revised and/or new versions of
580     the GNU General Public License from time to time. Such new versions will
581     be similar in spirit to the present version, but may differ in detail to
582     address new problems or concerns.
583    
584     Each version is given a distinguishing version number. If the
585     Program specifies that a certain numbered version of the GNU General
586     Public License "or any later version" applies to it, you have the
587     option of following the terms and conditions either of that numbered
588     version or of any later version published by the Free Software
589     Foundation. If the Program does not specify a version number of the
590     GNU General Public License, you may choose any version ever published
591     by the Free Software Foundation.
592    
593     If the Program specifies that a proxy can decide which future
594     versions of the GNU General Public License can be used, that proxy's
595     public statement of acceptance of a version permanently authorizes you
596     to choose that version for the Program.
597    
598     Later license versions may give you additional or different
599     permissions. However, no additional obligations are imposed on any
600     author or copyright holder as a result of your choosing to follow a
601     later version.
602    
603     15. Disclaimer of Warranty.
604    
605     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
606     APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
607     HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
608     OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
609     THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
610     PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
611     IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
612     ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
613    
614     16. Limitation of Liability.
615    
616     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
617     WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
618     THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
619     GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
620     USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
621     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
622     PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
623     EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
624     SUCH DAMAGES.
625    
626     17. Interpretation of Sections 15 and 16.
627    
628     If the disclaimer of warranty and limitation of liability provided
629     above cannot be given local legal effect according to their terms,
630     reviewing courts shall apply local law that most closely approximates
631     an absolute waiver of all civil liability in connection with the
632     Program, unless a warranty or assumption of liability accompanies a
633     copy of the Program in return for a fee.
634    
635     END OF TERMS AND CONDITIONS
636    
637     How to Apply These Terms to Your New Programs
638    
639     If you develop a new program, and you want it to be of the greatest
640     possible use to the public, the best way to achieve this is to make it
641     free software which everyone can redistribute and change under these terms.
642    
643     To do so, attach the following notices to the program. It is safest
644     to attach them to the start of each source file to most effectively
645     state the exclusion of warranty; and each file should have at least
646     the "copyright" line and a pointer to where the full notice is found.
647    
648     <one line to give the program's name and a brief idea of what it does.>
649     Copyright (C) <year> <name of author>
650    
651     This program is free software: you can redistribute it and/or modify
652     it under the terms of the GNU General Public License as published by
653     the Free Software Foundation, either version 3 of the License, or
654     (at your option) any later version.
655    
656     This program is distributed in the hope that it will be useful,
657     but WITHOUT ANY WARRANTY; without even the implied warranty of
658     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
659     GNU General Public License for more details.
660    
661     You should have received a copy of the GNU General Public License
662     along with this program. If not, see <http://www.gnu.org/licenses/>.
663    
664     Also add information on how to contact you by electronic and paper mail.
665    
666     If the program does terminal interaction, make it output a short
667     notice like this when it starts in an interactive mode:
668    
669     <program> Copyright (C) <year> <name of author>
670     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
671     This is free software, and you are welcome to redistribute it
672     under certain conditions; type `show c' for details.
673    
674     The hypothetical commands `show w' and `show c' should show the appropriate
675     parts of the General Public License. Of course, your program's commands
676     might be different; for a GUI interface, you would use an "about box".
677    
678     You should also get your employer (if you work as a programmer) or school,
679     if any, to sign a "copyright disclaimer" for the program, if necessary.
680     For more information on this, and how to apply and follow the GNU GPL, see
681     <http://www.gnu.org/licenses/>.
682    
683     The GNU General Public License does not permit incorporating your program
684     into proprietary programs. If your program is a subroutine library, you
685     may consider it more useful to permit linking proprietary applications with
686     the library. If this is what you want to do, use the GNU Lesser General
687     Public License instead of this License. But first, please read
688     <http://www.gnu.org/philosophy/why-not-lgpl.html>.
