1 root 1.3 Take note of the GNU Affero License (COPYING.Affero), which applies to
2     part of this release, which means you have to follow the requirements laid
3     out in section 13. of both licenses.

5     Note that ALL changed introduced by the Deliantra team are under the
6     Affero GNU Public License.
7 root 1.1
8     GNU GENERAL PUBLIC LICENSE
9     Version 3, 29 June 2007
10    
11     Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
12     Everyone is permitted to copy and distribute verbatim copies
13     of this license document, but changing it is not allowed.
14    
15     Preamble
16    
17     The GNU General Public License is a free, copyleft license for
18     software and other kinds of works.
19    
20     The licenses for most software and other practical works are designed
21     to take away your freedom to share and change the works. By contrast,
22     the GNU General Public License is intended to guarantee your freedom to
23     share and change all versions of a program--to make sure it remains free
24     software for all its users. We, the Free Software Foundation, use the
25     GNU General Public License for most of our software; it applies also to
26     any other work released this way by its authors. You can apply it to
27     your programs, too.
28    
29     When we speak of free software, we are referring to freedom, not
30     price. Our General Public Licenses are designed to make sure that you
31     have the freedom to distribute copies of free software (and charge for
32     them if you wish), that you receive source code or can get it if you
33     want it, that you can change the software or use pieces of it in new
34     free programs, and that you know you can do these things.
35    
36     To protect your rights, we need to prevent others from denying you
37     these rights or asking you to surrender the rights. Therefore, you have
38     certain responsibilities if you distribute copies of the software, or if
39     you modify it: responsibilities to respect the freedom of others.
40    
41     For example, if you distribute copies of such a program, whether
42     gratis or for a fee, you must pass on to the recipients the same
43     freedoms that you received. You must make sure that they, too, receive
44     or can get the source code. And you must show them these terms so they
45     know their rights.
46    
47     Developers that use the GNU GPL protect your rights with two steps:
48     (1) assert copyright on the software, and (2) offer you this License
49     giving you legal permission to copy, distribute and/or modify it.
50    
51     For the developers' and authors' protection, the GPL clearly explains
52     that there is no warranty for this free software. For both users' and
53     authors' sake, the GPL requires that modified versions be marked as
54     changed, so that their problems will not be attributed erroneously to
55     authors of previous versions.
56    
57     Some devices are designed to deny users access to install or run
58     modified versions of the software inside them, although the manufacturer
59     can do so. This is fundamentally incompatible with the aim of
60     protecting users' freedom to change the software. The systematic
61     pattern of such abuse occurs in the area of products for individuals to
62     use, which is precisely where it is most unacceptable. Therefore, we
63     have designed this version of the GPL to prohibit the practice for those
64     products. If such problems arise substantially in other domains, we
65     stand ready to extend this provision to those domains in future versions
66     of the GPL, as needed to protect the freedom of users.
67    
68     Finally, every program is threatened constantly by software patents.
69     States should not allow patents to restrict development and use of
70     software on general-purpose computers, but in those that do, we wish to
71     avoid the special danger that patents applied to a free program could
72     make it effectively proprietary. To prevent this, the GPL assures that
73     patents cannot be used to render the program non-free.
74    
75     The precise terms and conditions for copying, distribution and
76     modification follow.
77    
78     TERMS AND CONDITIONS
79    
80     0. Definitions.
81    
82     "This License" refers to version 3 of the GNU General Public License.
83    
84     "Copyright" also means copyright-like laws that apply to other kinds of
85     works, such as semiconductor masks.
86    
87     "The Program" refers to any copyrightable work licensed under this
88     License. Each licensee is addressed as "you". "Licensees" and
89     "recipients" may be individuals or organizations.
90    
91     To "modify" a work means to copy from or adapt all or part of the work
92     in a fashion requiring copyright permission, other than the making of an
93     exact copy. The resulting work is called a "modified version" of the
94     earlier work or a work "based on" the earlier work.
95    
96     A "covered work" means either the unmodified Program or a work based
97     on the Program.
98    
99     To "propagate" a work means to do anything with it that, without
100     permission, would make you directly or secondarily liable for
101     infringement under applicable copyright law, except executing it on a
102     computer or modifying a private copy. Propagation includes copying,
103     distribution (with or without modification), making available to the
104     public, and in some countries other activities as well.
105    
106     To "convey" a work means any kind of propagation that enables other
107     parties to make or receive copies. Mere interaction with a user through
108     a computer network, with no transfer of a copy, is not conveying.
109    
110     An interactive user interface displays "Appropriate Legal Notices"
111     to the extent that it includes a convenient and prominently visible
112     feature that (1) displays an appropriate copyright notice, and (2)
113     tells the user that there is no warranty for the work (except to the
114     extent that warranties are provided), that licensees may convey the
115     work under this License, and how to view a copy of this License. If
116     the interface presents a list of user commands or options, such as a
117     menu, a prominent item in the list meets this criterion.
118    
119     1. Source Code.
120    
121     The "source code" for a work means the preferred form of the work
122     for making modifications to it. "Object code" means any non-source
123     form of a work.
124    
125     A "Standard Interface" means an interface that either is an official
126     standard defined by a recognized standards body, or, in the case of
127     interfaces specified for a particular programming language, one that
128     is widely used among developers working in that language.
129    
130     The "System Libraries" of an executable work include anything, other
131     than the work as a whole, that (a) is included in the normal form of
132     packaging a Major Component, but which is not part of that Major
133     Component, and (b) serves only to enable use of the work with that
134     Major Component, or to implement a Standard Interface for which an
135     implementation is available to the public in source code form. A
136     "Major Component", in this context, means a major essential component
137     (kernel, window system, and so on) of the specific operating system
138     (if any) on which the executable work runs, or a compiler used to
139     produce the work, or an object code interpreter used to run it.
140    
141     The "Corresponding Source" for a work in object code form means all
142     the source code needed to generate, install, and (for an executable
143     work) run the object code and to modify the work, including scripts to
144     control those activities. However, it does not include the work's
145     System Libraries, or general-purpose tools or generally available free
146     programs which are used unmodified in performing those activities but
147     which are not part of the work. For example, Corresponding Source
148     includes interface definition files associated with source files for
149     the work, and the source code for shared libraries and dynamically
150     linked subprograms that the work is specifically designed to require,
151     such as by intimate data communication or control flow between those
152     subprograms and other parts of the work.
153    
154     The Corresponding Source need not include anything that users
155     can regenerate automatically from other parts of the Corresponding
156     Source.
157    
158     The Corresponding Source for a work in source code form is that
159     same work.
160    
161     2. Basic Permissions.
162    
163     All rights granted under this License are granted for the term of
164     copyright on the Program, and are irrevocable provided the stated
165     conditions are met. This License explicitly affirms your unlimited
166     permission to run the unmodified Program. The output from running a
167     covered work is covered by this License only if the output, given its
168     content, constitutes a covered work. This License acknowledges your
169     rights of fair use or other equivalent, as provided by copyright law.
170    
171     You may make, run and propagate covered works that you do not
172     convey, without conditions so long as your license otherwise remains
173     in force. You may convey covered works to others for the sole purpose
174     of having them make modifications exclusively for you, or provide you
175     with facilities for running those works, provided that you comply with
176     the terms of this License in conveying all material for which you do
177     not control copyright. Those thus making or running the covered works
178     for you must do so exclusively on your behalf, under your direction
179     and control, on terms that prohibit them from making any copies of
180     your copyrighted material outside their relationship with you.
181    
182     Conveying under any other circumstances is permitted solely under
183     the conditions stated below. Sublicensing is not allowed; section 10
184     makes it unnecessary.
185    
186     3. Protecting Users' Legal Rights From Anti-Circumvention Law.
187    
188     No covered work shall be deemed part of an effective technological
189     measure under any applicable law fulfilling obligations under article
190     11 of the WIPO copyright treaty adopted on 20 December 1996, or
191     similar laws prohibiting or restricting circumvention of such
192     measures.
193    
194     When you convey a covered work, you waive any legal power to forbid
195     circumvention of technological measures to the extent such circumvention
196     is effected by exercising rights under this License with respect to
197     the covered work, and you disclaim any intention to limit operation or
198     modification of the work as a means of enforcing, against the work's
199     users, your or third parties' legal rights to forbid circumvention of
200     technological measures.
201    
202     4. Conveying Verbatim Copies.
203    
204     You may convey verbatim copies of the Program's source code as you
205     receive it, in any medium, provided that you conspicuously and
206     appropriately publish on each copy an appropriate copyright notice;
207     keep intact all notices stating that this License and any
208     non-permissive terms added in accord with section 7 apply to the code;
209     keep intact all notices of the absence of any warranty; and give all
210     recipients a copy of this License along with the Program.
211    
212     You may charge any price or no price for each copy that you convey,
213     and you may offer support or warranty protection for a fee.
214    
215     5. Conveying Modified Source Versions.
216    
217     You may convey a work based on the Program, or the modifications to
218     produce it from the Program, in the form of source code under the
219     terms of section 4, provided that you also meet all of these conditions:
220    
221     a) The work must carry prominent notices stating that you modified
222     it, and giving a relevant date.
223    
224     b) The work must carry prominent notices stating that it is
225     released under this License and any conditions added under section
226     7. This requirement modifies the requirement in section 4 to
227     "keep intact all notices".
228    
229     c) You must license the entire work, as a whole, under this
230     License to anyone who comes into possession of a copy. This
231     License will therefore apply, along with any applicable section 7
232     additional terms, to the whole of the work, and all its parts,
233     regardless of how they are packaged. This License gives no
234     permission to license the work in any other way, but it does not
235     invalidate such permission if you have separately received it.
236    
237     d) If the work has interactive user interfaces, each must display
238     Appropriate Legal Notices; however, if the Program has interactive
239     interfaces that do not display Appropriate Legal Notices, your
240     work need not make them do so.
241    
242     A compilation of a covered work with other separate and independent
243     works, which are not by their nature extensions of the covered work,
244     and which are not combined with it such as to form a larger program,
245     in or on a volume of a storage or distribution medium, is called an
246     "aggregate" if the compilation and its resulting copyright are not
247     used to limit the access or legal rights of the compilation's users
248     beyond what the individual works permit. Inclusion of a covered work
249     in an aggregate does not cause this License to apply to the other
250     parts of the aggregate.
251    
252     6. Conveying Non-Source Forms.
253    
254     You may convey a covered work in object code form under the terms
255     of sections 4 and 5, provided that you also convey the
256     machine-readable Corresponding Source under the terms of this License,
257     in one of these ways:
258    
259     a) Convey the object code in, or embodied in, a physical product
260     (including a physical distribution medium), accompanied by the
261     Corresponding Source fixed on a durable physical medium
262     customarily used for software interchange.
263    
264     b) Convey the object code in, or embodied in, a physical product
265     (including a physical distribution medium), accompanied by a
266     written offer, valid for at least three years and valid for as
267     long as you offer spare parts or customer support for that product
268     model, to give anyone who possesses the object code either (1) a
269     copy of the Corresponding Source for all the software in the
270     product that is covered by this License, on a durable physical
271     medium customarily used for software interchange, for a price no
272     more than your reasonable cost of physically performing this
273     conveying of source, or (2) access to copy the
274     Corresponding Source from a network server at no charge.
275    
276     c) Convey individual copies of the object code with a copy of the
277     written offer to provide the Corresponding Source. This
278     alternative is allowed only occasionally and noncommercially, and
279     only if you received the object code with such an offer, in accord
280     with subsection 6b.
281    
282     d) Convey the object code by offering access from a designated
283     place (gratis or for a charge), and offer equivalent access to the
284     Corresponding Source in the same way through the same place at no
285     further charge. You need not require recipients to copy the
286     Corresponding Source along with the object code. If the place to
287     copy the object code is a network server, the Corresponding Source
288     may be on a different server (operated by you or a third party)
289     that supports equivalent copying facilities, provided you maintain
290     clear directions next to the object code saying where to find the
291     Corresponding Source. Regardless of what server hosts the
292     Corresponding Source, you remain obligated to ensure that it is
293     available for as long as needed to satisfy these requirements.
294    
295     e) Convey the object code using peer-to-peer transmission, provided
296     you inform other peers where the object code and Corresponding
297     Source of the work are being offered to the general public at no
298     charge under subsection 6d.
299    
300     A separable portion of the object code, whose source code is excluded
301     from the Corresponding Source as a System Library, need not be
302     included in conveying the object code work.
303    
304     A "User Product" is either (1) a "consumer product", which means any
305     tangible personal property which is normally used for personal, family,
306     or household purposes, or (2) anything designed or sold for incorporation
307     into a dwelling. In determining whether a product is a consumer product,
308     doubtful cases shall be resolved in favor of coverage. For a particular
309     product received by a particular user, "normally used" refers to a
310     typical or common use of that class of product, regardless of the status
311     of the particular user or of the way in which the particular user
312     actually uses, or expects or is expected to use, the product. A product
313     is a consumer product regardless of whether the product has substantial
314     commercial, industrial or non-consumer uses, unless such uses represent
315     the only significant mode of use of the product.
316    
317     "Installation Information" for a User Product means any methods,
318     procedures, authorization keys, or other information required to install
319     and execute modified versions of a covered work in that User Product from
320     a modified version of its Corresponding Source. The information must
321     suffice to ensure that the continued functioning of the modified object
322     code is in no case prevented or interfered with solely because
323     modification has been made.
324    
325     If you convey an object code work under this section in, or with, or
326     specifically for use in, a User Product, and the conveying occurs as
327     part of a transaction in which the right of possession and use of the
328     User Product is transferred to the recipient in perpetuity or for a
329     fixed term (regardless of how the transaction is characterized), the
330     Corresponding Source conveyed under this section must be accompanied
331     by the Installation Information. But this requirement does not apply
332     if neither you nor any third party retains the ability to install
333     modified object code on the User Product (for example, the work has
334     been installed in ROM).
335    
336     The requirement to provide Installation Information does not include a
337     requirement to continue to provide support service, warranty, or updates
338     for a work that has been modified or installed by the recipient, or for
339     the User Product in which it has been modified or installed. Access to a
340     network may be denied when the modification itself materially and
341     adversely affects the operation of the network or violates the rules and
342     protocols for communication across the network.
343    
344     Corresponding Source conveyed, and Installation Information provided,
345     in accord with this section must be in a format that is publicly
346     documented (and with an implementation available to the public in
347     source code form), and must require no special password or key for
348     unpacking, reading or copying.
349    
350     7. Additional Terms.
351    
352     "Additional permissions" are terms that supplement the terms of this
353     License by making exceptions from one or more of its conditions.
354     Additional permissions that are applicable to the entire Program shall
355     be treated as though they were included in this License, to the extent
356     that they are valid under applicable law. If additional permissions
357     apply only to part of the Program, that part may be used separately
358     under those permissions, but the entire Program remains governed by
359     this License without regard to the additional permissions.
360    
361     When you convey a copy of a covered work, you may at your option
362     remove any additional permissions from that copy, or from any part of
363     it. (Additional permissions may be written to require their own
364     removal in certain cases when you modify the work.) You may place
365     additional permissions on material, added by you to a covered work,
366     for which you have or can give appropriate copyright permission.
367    
368     Notwithstanding any other provision of this License, for material you
369     add to a covered work, you may (if authorized by the copyright holders of
370     that material) supplement the terms of this License with terms:
371    
372     a) Disclaiming warranty or limiting liability differently from the
373     terms of sections 15 and 16 of this License; or
374    
375     b) Requiring preservation of specified reasonable legal notices or
376     author attributions in that material or in the Appropriate Legal
377     Notices displayed by works containing it; or
378    
379     c) Prohibiting misrepresentation of the origin of that material, or
380     requiring that modified versions of such material be marked in
381     reasonable ways as different from the original version; or
382    
383     d) Limiting the use for publicity purposes of names of licensors or
384     authors of the material; or
385    
386     e) Declining to grant rights under trademark law for use of some
387     trade names, trademarks, or service marks; or
388    
389     f) Requiring indemnification of licensors and authors of that
390     material by anyone who conveys the material (or modified versions of
391     it) with contractual assumptions of liability to the recipient, for
392     any liability that these contractual assumptions directly impose on
393     those licensors and authors.
394    
395     All other non-permissive additional terms are considered "further
396     restrictions" within the meaning of section 10. If the Program as you
397     received it, or any part of it, contains a notice stating that it is
398     governed by this License along with a term that is a further
399     restriction, you may remove that term. If a license document contains
400     a further restriction but permits relicensing or conveying under this
401     License, you may add to a covered work material governed by the terms
402     of that license document, provided that the further restriction does
403     not survive such relicensing or conveying.
404    
405     If you add terms to a covered work in accord with this section, you
406     must place, in the relevant source files, a statement of the
407     additional terms that apply to those files, or a notice indicating
408     where to find the applicable terms.
409    
410     Additional terms, permissive or non-permissive, may be stated in the
411     form of a separately written license, or stated as exceptions;
412     the above requirements apply either way.
413    
414     8. Termination.
415    
416     You may not propagate or modify a covered work except as expressly
417     provided under this License. Any attempt otherwise to propagate or
418     modify it is void, and will automatically terminate your rights under
419     this License (including any patent licenses granted under the third
420     paragraph of section 11).
421    
422     However, if you cease all violation of this License, then your
423     license from a particular copyright holder is reinstated (a)
424     provisionally, unless and until the copyright holder explicitly and
425     finally terminates your license, and (b) permanently, if the copyright
426     holder fails to notify you of the violation by some reasonable means
427     prior to 60 days after the cessation.
428    
429     Moreover, your license from a particular copyright holder is
430     reinstated permanently if the copyright holder notifies you of the
431     violation by some reasonable means, this is the first time you have
432     received notice of violation of this License (for any work) from that
433     copyright holder, and you cure the violation prior to 30 days after
434     your receipt of the notice.
435    
436     Termination of your rights under this section does not terminate the
437     licenses of parties who have received copies or rights from you under
438     this License. If your rights have been terminated and not permanently
439     reinstated, you do not qualify to receive new licenses for the same
440     material under section 10.
441    
442     9. Acceptance Not Required for Having Copies.
443    
444     You are not required to accept this License in order to receive or
445     run a copy of the Program. Ancillary propagation of a covered work
446     occurring solely as a consequence of using peer-to-peer transmission
447     to receive a copy likewise does not require acceptance. However,
448     nothing other than this License grants you permission to propagate or
449     modify any covered work. These actions infringe copyright if you do
450     not accept this License. Therefore, by modifying or propagating a
451     covered work, you indicate your acceptance of this License to do so.
452    
453     10. Automatic Licensing of Downstream Recipients.
454    
455     Each time you convey a covered work, the recipient automatically
456     receives a license from the original licensors, to run, modify and
457     propagate that work, subject to this License. You are not responsible
458     for enforcing compliance by third parties with this License.
459    
460     An "entity transaction" is a transaction transferring control of an
461     organization, or substantially all assets of one, or subdividing an
462     organization, or merging organizations. If propagation of a covered
463     work results from an entity transaction, each party to that
464     transaction who receives a copy of the work also receives whatever
465     licenses to the work the party's predecessor in interest had or could
466     give under the previous paragraph, plus a right to possession of the
467     Corresponding Source of the work from the predecessor in interest, if
468     the predecessor has it or can get it with reasonable efforts.
469    
470     You may not impose any further restrictions on the exercise of the
471     rights granted or affirmed under this License. For example, you may
472     not impose a license fee, royalty, or other charge for exercise of
473     rights granted under this License, and you may not initiate litigation
474     (including a cross-claim or counterclaim in a lawsuit) alleging that
475     any patent claim is infringed by making, using, selling, offering for
476     sale, or importing the Program or any portion of it.
477    
478     11. Patents.
479    
480     A "contributor" is a copyright holder who authorizes use under this
481     License of the Program or a work on which the Program is based. The
482     work thus licensed is called the contributor's "contributor version".
483    
484     A contributor's "essential patent claims" are all patent claims
485     owned or controlled by the contributor, whether already acquired or
486     hereafter acquired, that would be infringed by some manner, permitted
487     by this License, of making, using, or selling its contributor version,
488     but do not include claims that would be infringed only as a
489     consequence of further modification of the contributor version. For
490     purposes of this definition, "control" includes the right to grant
491     patent sublicenses in a manner consistent with the requirements of
492     this License.
493    
494     Each contributor grants you a non-exclusive, worldwide, royalty-free
495     patent license under the contributor's essential patent claims, to
496     make, use, sell, offer for sale, import and otherwise run, modify and
497     propagate the contents of its contributor version.
498    
499     In the following three paragraphs, a "patent license" is any express
500     agreement or commitment, however denominated, not to enforce a patent
501     (such as an express permission to practice a patent or covenant not to
502     sue for patent infringement). To "grant" such a patent license to a
503     party means to make such an agreement or commitment not to enforce a
504     patent against the party.
505    
506     If you convey a covered work, knowingly relying on a patent license,
507     and the Corresponding Source of the work is not available for anyone
508     to copy, free of charge and under the terms of this License, through a
509     publicly available network server or other readily accessible means,
510     then you must either (1) cause the Corresponding Source to be so
511     available, or (2) arrange to deprive yourself of the benefit of the
512     patent license for this particular work, or (3) arrange, in a manner
513     consistent with the requirements of this License, to extend the patent
514     license to downstream recipients. "Knowingly relying" means you have
515     actual knowledge that, but for the patent license, your conveying the
516     covered work in a country, or your recipient's use of the covered work
517     in a country, would infringe one or more identifiable patents in that
518     country that you have reason to believe are valid.
519    
520     If, pursuant to or in connection with a single transaction or
521     arrangement, you convey, or propagate by procuring conveyance of, a
522     covered work, and grant a patent license to some of the parties
523     receiving the covered work authorizing them to use, propagate, modify
524     or convey a specific copy of the covered work, then the patent license
525     you grant is automatically extended to all recipients of the covered
526     work and works based on it.
527    
528     A patent license is "discriminatory" if it does not include within
529     the scope of its coverage, prohibits the exercise of, or is
530     conditioned on the non-exercise of one or more of the rights that are
531     specifically granted under this License. You may not convey a covered
532     work if you are a party to an arrangement with a third party that is
533     in the business of distributing software, under which you make payment
534     to the third party based on the extent of your activity of conveying
535     the work, and under which the third party grants, to any of the
536     parties who would receive the covered work from you, a discriminatory
537     patent license (a) in connection with copies of the covered work
538     conveyed by you (or copies made from those copies), or (b) primarily
539     for and in connection with specific products or compilations that
540     contain the covered work, unless you entered into that arrangement,
541     or that patent license was granted, prior to 28 March 2007.
542    
543     Nothing in this License shall be construed as excluding or limiting
544     any implied license or other defenses to infringement that may
545     otherwise be available to you under applicable patent law.
546    
547     12. No Surrender of Others' Freedom.
548    
549     If conditions are imposed on you (whether by court order, agreement or
550     otherwise) that contradict the conditions of this License, they do not
551     excuse you from the conditions of this License. If you cannot convey a
552     covered work so as to satisfy simultaneously your obligations under this
553     License and any other pertinent obligations, then as a consequence you may
554     not convey it at all. For example, if you agree to terms that obligate you
555     to collect a royalty for further conveying from those to whom you convey
556     the Program, the only way you could satisfy both those terms and this
557     License would be to refrain entirely from conveying the Program.
558    
559     13. Use with the GNU Affero General Public License.
560    
561     Notwithstanding any other provision of this License, you have
562     permission to link or combine any covered work with a work licensed
563     under version 3 of the GNU Affero General Public License into a single
564     combined work, and to convey the resulting work. The terms of this
565     License will continue to apply to the part which is the covered work,
566     but the special requirements of the GNU Affero General Public License,
567     section 13, concerning interaction through a network will apply to the
568     combination as such.
569    
570     14. Revised Versions of this License.
571    
572     The Free Software Foundation may publish revised and/or new versions of
573     the GNU General Public License from time to time. Such new versions will
574     be similar in spirit to the present version, but may differ in detail to
575     address new problems or concerns.
576    
577     Each version is given a distinguishing version number. If the
578     Program specifies that a certain numbered version of the GNU General
579     Public License "or any later version" applies to it, you have the
580     option of following the terms and conditions either of that numbered
581     version or of any later version published by the Free Software
582     Foundation. If the Program does not specify a version number of the
583     GNU General Public License, you may choose any version ever published
584     by the Free Software Foundation.
585    
586     If the Program specifies that a proxy can decide which future
587     versions of the GNU General Public License can be used, that proxy's
588     public statement of acceptance of a version permanently authorizes you
589     to choose that version for the Program.
590    
591     Later license versions may give you additional or different
592     permissions. However, no additional obligations are imposed on any
593     author or copyright holder as a result of your choosing to follow a
594     later version.
595    
596     15. Disclaimer of Warranty.
597    
598     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
599     APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
600     HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
601     OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
602     THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
603     PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
604     IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
605     ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
606    
607     16. Limitation of Liability.
608    
609     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
610     WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
611     THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
612     GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
613     USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
614     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
615     PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
616     EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
617     SUCH DAMAGES.
618    
619     17. Interpretation of Sections 15 and 16.
620    
621     If the disclaimer of warranty and limitation of liability provided
622     above cannot be given local legal effect according to their terms,
623     reviewing courts shall apply local law that most closely approximates
624     an absolute waiver of all civil liability in connection with the
625     Program, unless a warranty or assumption of liability accompanies a
626     copy of the Program in return for a fee.
627    
628     END OF TERMS AND CONDITIONS
629    
630     How to Apply These Terms to Your New Programs
631    
632     If you develop a new program, and you want it to be of the greatest
633     possible use to the public, the best way to achieve this is to make it
634     free software which everyone can redistribute and change under these terms.
635    
636     To do so, attach the following notices to the program. It is safest
637     to attach them to the start of each source file to most effectively
638     state the exclusion of warranty; and each file should have at least
639     the "copyright" line and a pointer to where the full notice is found.
640    
641     <one line to give the program's name and a brief idea of what it does.>
642     Copyright (C) <year> <name of author>
643    
644     This program is free software: you can redistribute it and/or modify
645     it under the terms of the GNU General Public License as published by
646     the Free Software Foundation, either version 3 of the License, or
647     (at your option) any later version.
648    
649     This program is distributed in the hope that it will be useful,
650     but WITHOUT ANY WARRANTY; without even the implied warranty of
651     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
652     GNU General Public License for more details.
653    
654     You should have received a copy of the GNU General Public License
655     along with this program. If not, see <http://www.gnu.org/licenses/>.
656    
657     Also add information on how to contact you by electronic and paper mail.
658    
659     If the program does terminal interaction, make it output a short
660     notice like this when it starts in an interactive mode:
661    
662     <program> Copyright (C) <year> <name of author>
663     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
664     This is free software, and you are welcome to redistribute it
665     under certain conditions; type `show c' for details.
666    
667     The hypothetical commands `show w' and `show c' should show the appropriate
668     parts of the General Public License. Of course, your program's commands
669     might be different; for a GUI interface, you would use an "about box".
670    
671     You should also get your employer (if you work as a programmer) or school,
672     if any, to sign a "copyright disclaimer" for the program, if necessary.
673     For more information on this, and how to apply and follow the GNU GPL, see
674     <http://www.gnu.org/licenses/>.
675    
676     The GNU General Public License does not permit incorporating your program
677     into proprietary programs. If your program is a subroutine library, you
678     may consider it more useful to permit linking proprietary applications with
679     the library. If this is what you want to do, use the GNU Lesser General
680     Public License instead of this License. But first, please read
681     <http://www.gnu.org/philosophy/why-not-lgpl.html>.
