1 root 1.2 Take note of the GNU Affero License (COPYING.GNU), which applies to part
2     of this release, which means you have to follow the requirements laid out
3     in section 13. of both licenses.
4 root 1.1
5     GNU GENERAL PUBLIC LICENSE
6     Version 3, 29 June 2007
7    
8     Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
9     Everyone is permitted to copy and distribute verbatim copies
10     of this license document, but changing it is not allowed.
11    
12     Preamble
13    
14     The GNU General Public License is a free, copyleft license for
15     software and other kinds of works.
16    
17     The licenses for most software and other practical works are designed
18     to take away your freedom to share and change the works. By contrast,
19     the GNU General Public License is intended to guarantee your freedom to
20     share and change all versions of a program--to make sure it remains free
21     software for all its users. We, the Free Software Foundation, use the
22     GNU General Public License for most of our software; it applies also to
23     any other work released this way by its authors. You can apply it to
24     your programs, too.
25    
26     When we speak of free software, we are referring to freedom, not
27     price. Our General Public Licenses are designed to make sure that you
28     have the freedom to distribute copies of free software (and charge for
29     them if you wish), that you receive source code or can get it if you
30     want it, that you can change the software or use pieces of it in new
31     free programs, and that you know you can do these things.
32    
33     To protect your rights, we need to prevent others from denying you
34     these rights or asking you to surrender the rights. Therefore, you have
35     certain responsibilities if you distribute copies of the software, or if
36     you modify it: responsibilities to respect the freedom of others.
37    
38     For example, if you distribute copies of such a program, whether
39     gratis or for a fee, you must pass on to the recipients the same
40     freedoms that you received. You must make sure that they, too, receive
41     or can get the source code. And you must show them these terms so they
42     know their rights.
43    
44     Developers that use the GNU GPL protect your rights with two steps:
45     (1) assert copyright on the software, and (2) offer you this License
46     giving you legal permission to copy, distribute and/or modify it.
47    
48     For the developers' and authors' protection, the GPL clearly explains
49     that there is no warranty for this free software. For both users' and
50     authors' sake, the GPL requires that modified versions be marked as
51     changed, so that their problems will not be attributed erroneously to
52     authors of previous versions.
53    
54     Some devices are designed to deny users access to install or run
55     modified versions of the software inside them, although the manufacturer
56     can do so. This is fundamentally incompatible with the aim of
57     protecting users' freedom to change the software. The systematic
58     pattern of such abuse occurs in the area of products for individuals to
59     use, which is precisely where it is most unacceptable. Therefore, we
60     have designed this version of the GPL to prohibit the practice for those
61     products. If such problems arise substantially in other domains, we
62     stand ready to extend this provision to those domains in future versions
63     of the GPL, as needed to protect the freedom of users.
64    
65     Finally, every program is threatened constantly by software patents.
66     States should not allow patents to restrict development and use of
67     software on general-purpose computers, but in those that do, we wish to
68     avoid the special danger that patents applied to a free program could
69     make it effectively proprietary. To prevent this, the GPL assures that
70     patents cannot be used to render the program non-free.
71    
72     The precise terms and conditions for copying, distribution and
73     modification follow.
74    
75     TERMS AND CONDITIONS
76    
77     0. Definitions.
78    
79     "This License" refers to version 3 of the GNU General Public License.
80    
81     "Copyright" also means copyright-like laws that apply to other kinds of
82     works, such as semiconductor masks.
83    
84     "The Program" refers to any copyrightable work licensed under this
85     License. Each licensee is addressed as "you". "Licensees" and
86     "recipients" may be individuals or organizations.
87    
88     To "modify" a work means to copy from or adapt all or part of the work
89     in a fashion requiring copyright permission, other than the making of an
90     exact copy. The resulting work is called a "modified version" of the
91     earlier work or a work "based on" the earlier work.
92    
93     A "covered work" means either the unmodified Program or a work based
94     on the Program.
95    
96     To "propagate" a work means to do anything with it that, without
97     permission, would make you directly or secondarily liable for
98     infringement under applicable copyright law, except executing it on a
99     computer or modifying a private copy. Propagation includes copying,
100     distribution (with or without modification), making available to the
101     public, and in some countries other activities as well.
102    
103     To "convey" a work means any kind of propagation that enables other
104     parties to make or receive copies. Mere interaction with a user through
105     a computer network, with no transfer of a copy, is not conveying.
106    
107     An interactive user interface displays "Appropriate Legal Notices"
108     to the extent that it includes a convenient and prominently visible
109     feature that (1) displays an appropriate copyright notice, and (2)
110     tells the user that there is no warranty for the work (except to the
111     extent that warranties are provided), that licensees may convey the
112     work under this License, and how to view a copy of this License. If
113     the interface presents a list of user commands or options, such as a
114     menu, a prominent item in the list meets this criterion.
115    
116     1. Source Code.
117    
118     The "source code" for a work means the preferred form of the work
119     for making modifications to it. "Object code" means any non-source
120     form of a work.
121    
122     A "Standard Interface" means an interface that either is an official
123     standard defined by a recognized standards body, or, in the case of
124     interfaces specified for a particular programming language, one that
125     is widely used among developers working in that language.
126    
127     The "System Libraries" of an executable work include anything, other
128     than the work as a whole, that (a) is included in the normal form of
129     packaging a Major Component, but which is not part of that Major
130     Component, and (b) serves only to enable use of the work with that
131     Major Component, or to implement a Standard Interface for which an
132     implementation is available to the public in source code form. A
133     "Major Component", in this context, means a major essential component
134     (kernel, window system, and so on) of the specific operating system
135     (if any) on which the executable work runs, or a compiler used to
136     produce the work, or an object code interpreter used to run it.
137    
138     The "Corresponding Source" for a work in object code form means all
139     the source code needed to generate, install, and (for an executable
140     work) run the object code and to modify the work, including scripts to
141     control those activities. However, it does not include the work's
142     System Libraries, or general-purpose tools or generally available free
143     programs which are used unmodified in performing those activities but
144     which are not part of the work. For example, Corresponding Source
145     includes interface definition files associated with source files for
146     the work, and the source code for shared libraries and dynamically
147     linked subprograms that the work is specifically designed to require,
148     such as by intimate data communication or control flow between those
149     subprograms and other parts of the work.
150    
151     The Corresponding Source need not include anything that users
152     can regenerate automatically from other parts of the Corresponding
153     Source.
154    
155     The Corresponding Source for a work in source code form is that
156     same work.
157    
158     2. Basic Permissions.
159    
160     All rights granted under this License are granted for the term of
161     copyright on the Program, and are irrevocable provided the stated
162     conditions are met. This License explicitly affirms your unlimited
163     permission to run the unmodified Program. The output from running a
164     covered work is covered by this License only if the output, given its
165     content, constitutes a covered work. This License acknowledges your
166     rights of fair use or other equivalent, as provided by copyright law.
167    
168     You may make, run and propagate covered works that you do not
169     convey, without conditions so long as your license otherwise remains
170     in force. You may convey covered works to others for the sole purpose
171     of having them make modifications exclusively for you, or provide you
172     with facilities for running those works, provided that you comply with
173     the terms of this License in conveying all material for which you do
174     not control copyright. Those thus making or running the covered works
175     for you must do so exclusively on your behalf, under your direction
176     and control, on terms that prohibit them from making any copies of
177     your copyrighted material outside their relationship with you.
178    
179     Conveying under any other circumstances is permitted solely under
180     the conditions stated below. Sublicensing is not allowed; section 10
181     makes it unnecessary.
182    
183     3. Protecting Users' Legal Rights From Anti-Circumvention Law.
184    
185     No covered work shall be deemed part of an effective technological
186     measure under any applicable law fulfilling obligations under article
187     11 of the WIPO copyright treaty adopted on 20 December 1996, or
188     similar laws prohibiting or restricting circumvention of such
189     measures.
190    
191     When you convey a covered work, you waive any legal power to forbid
192     circumvention of technological measures to the extent such circumvention
193     is effected by exercising rights under this License with respect to
194     the covered work, and you disclaim any intention to limit operation or
195     modification of the work as a means of enforcing, against the work's
196     users, your or third parties' legal rights to forbid circumvention of
197     technological measures.
198    
199     4. Conveying Verbatim Copies.
200    
201     You may convey verbatim copies of the Program's source code as you
202     receive it, in any medium, provided that you conspicuously and
203     appropriately publish on each copy an appropriate copyright notice;
204     keep intact all notices stating that this License and any
205     non-permissive terms added in accord with section 7 apply to the code;
206     keep intact all notices of the absence of any warranty; and give all
207     recipients a copy of this License along with the Program.
208    
209     You may charge any price or no price for each copy that you convey,
210     and you may offer support or warranty protection for a fee.
211    
212     5. Conveying Modified Source Versions.
213    
214     You may convey a work based on the Program, or the modifications to
215     produce it from the Program, in the form of source code under the
216     terms of section 4, provided that you also meet all of these conditions:
217    
218     a) The work must carry prominent notices stating that you modified
219     it, and giving a relevant date.
220    
221     b) The work must carry prominent notices stating that it is
222     released under this License and any conditions added under section
223     7. This requirement modifies the requirement in section 4 to
224     "keep intact all notices".
225    
226     c) You must license the entire work, as a whole, under this
227     License to anyone who comes into possession of a copy. This
228     License will therefore apply, along with any applicable section 7
229     additional terms, to the whole of the work, and all its parts,
230     regardless of how they are packaged. This License gives no
231     permission to license the work in any other way, but it does not
232     invalidate such permission if you have separately received it.
233    
234     d) If the work has interactive user interfaces, each must display
235     Appropriate Legal Notices; however, if the Program has interactive
236     interfaces that do not display Appropriate Legal Notices, your
237     work need not make them do so.
238    
239     A compilation of a covered work with other separate and independent
240     works, which are not by their nature extensions of the covered work,
241     and which are not combined with it such as to form a larger program,
242     in or on a volume of a storage or distribution medium, is called an
243     "aggregate" if the compilation and its resulting copyright are not
244     used to limit the access or legal rights of the compilation's users
245     beyond what the individual works permit. Inclusion of a covered work
246     in an aggregate does not cause this License to apply to the other
247     parts of the aggregate.
248    
249     6. Conveying Non-Source Forms.
250    
251     You may convey a covered work in object code form under the terms
252     of sections 4 and 5, provided that you also convey the
253     machine-readable Corresponding Source under the terms of this License,
254     in one of these ways:
255    
256     a) Convey the object code in, or embodied in, a physical product
257     (including a physical distribution medium), accompanied by the
258     Corresponding Source fixed on a durable physical medium
259     customarily used for software interchange.
260    
261     b) Convey the object code in, or embodied in, a physical product
262     (including a physical distribution medium), accompanied by a
263     written offer, valid for at least three years and valid for as
264     long as you offer spare parts or customer support for that product
265     model, to give anyone who possesses the object code either (1) a
266     copy of the Corresponding Source for all the software in the
267     product that is covered by this License, on a durable physical
268     medium customarily used for software interchange, for a price no
269     more than your reasonable cost of physically performing this
270     conveying of source, or (2) access to copy the
271     Corresponding Source from a network server at no charge.
272    
273     c) Convey individual copies of the object code with a copy of the
274     written offer to provide the Corresponding Source. This
275     alternative is allowed only occasionally and noncommercially, and
276     only if you received the object code with such an offer, in accord
277     with subsection 6b.
278    
279     d) Convey the object code by offering access from a designated
280     place (gratis or for a charge), and offer equivalent access to the
281     Corresponding Source in the same way through the same place at no
282     further charge. You need not require recipients to copy the
283     Corresponding Source along with the object code. If the place to
284     copy the object code is a network server, the Corresponding Source
285     may be on a different server (operated by you or a third party)
286     that supports equivalent copying facilities, provided you maintain
287     clear directions next to the object code saying where to find the
288     Corresponding Source. Regardless of what server hosts the
289     Corresponding Source, you remain obligated to ensure that it is
290     available for as long as needed to satisfy these requirements.
291    
292     e) Convey the object code using peer-to-peer transmission, provided
293     you inform other peers where the object code and Corresponding
294     Source of the work are being offered to the general public at no
295     charge under subsection 6d.
296    
297     A separable portion of the object code, whose source code is excluded
298     from the Corresponding Source as a System Library, need not be
299     included in conveying the object code work.
300    
301     A "User Product" is either (1) a "consumer product", which means any
302     tangible personal property which is normally used for personal, family,
303     or household purposes, or (2) anything designed or sold for incorporation
304     into a dwelling. In determining whether a product is a consumer product,
305     doubtful cases shall be resolved in favor of coverage. For a particular
306     product received by a particular user, "normally used" refers to a
307     typical or common use of that class of product, regardless of the status
308     of the particular user or of the way in which the particular user
309     actually uses, or expects or is expected to use, the product. A product
310     is a consumer product regardless of whether the product has substantial
311     commercial, industrial or non-consumer uses, unless such uses represent
312     the only significant mode of use of the product.
313    
314     "Installation Information" for a User Product means any methods,
315     procedures, authorization keys, or other information required to install
316     and execute modified versions of a covered work in that User Product from
317     a modified version of its Corresponding Source. The information must
318     suffice to ensure that the continued functioning of the modified object
319     code is in no case prevented or interfered with solely because
320     modification has been made.
321    
322     If you convey an object code work under this section in, or with, or
323     specifically for use in, a User Product, and the conveying occurs as
324     part of a transaction in which the right of possession and use of the
325     User Product is transferred to the recipient in perpetuity or for a
326     fixed term (regardless of how the transaction is characterized), the
327     Corresponding Source conveyed under this section must be accompanied
328     by the Installation Information. But this requirement does not apply
329     if neither you nor any third party retains the ability to install
330     modified object code on the User Product (for example, the work has
331     been installed in ROM).
332    
333     The requirement to provide Installation Information does not include a
334     requirement to continue to provide support service, warranty, or updates
335     for a work that has been modified or installed by the recipient, or for
336     the User Product in which it has been modified or installed. Access to a
337     network may be denied when the modification itself materially and
338     adversely affects the operation of the network or violates the rules and
339     protocols for communication across the network.
340    
341     Corresponding Source conveyed, and Installation Information provided,
342     in accord with this section must be in a format that is publicly
343     documented (and with an implementation available to the public in
344     source code form), and must require no special password or key for
345     unpacking, reading or copying.
346    
347     7. Additional Terms.
348    
349     "Additional permissions" are terms that supplement the terms of this
350     License by making exceptions from one or more of its conditions.
351     Additional permissions that are applicable to the entire Program shall
352     be treated as though they were included in this License, to the extent
353     that they are valid under applicable law. If additional permissions
354     apply only to part of the Program, that part may be used separately
355     under those permissions, but the entire Program remains governed by
356     this License without regard to the additional permissions.
357    
358     When you convey a copy of a covered work, you may at your option
359     remove any additional permissions from that copy, or from any part of
360     it. (Additional permissions may be written to require their own
361     removal in certain cases when you modify the work.) You may place
362     additional permissions on material, added by you to a covered work,
363     for which you have or can give appropriate copyright permission.
364    
365     Notwithstanding any other provision of this License, for material you
366     add to a covered work, you may (if authorized by the copyright holders of
367     that material) supplement the terms of this License with terms:
368    
369     a) Disclaiming warranty or limiting liability differently from the
370     terms of sections 15 and 16 of this License; or
371    
372     b) Requiring preservation of specified reasonable legal notices or
373     author attributions in that material or in the Appropriate Legal
374     Notices displayed by works containing it; or
375    
376     c) Prohibiting misrepresentation of the origin of that material, or
377     requiring that modified versions of such material be marked in
378     reasonable ways as different from the original version; or
379    
380     d) Limiting the use for publicity purposes of names of licensors or
381     authors of the material; or
382    
383     e) Declining to grant rights under trademark law for use of some
384     trade names, trademarks, or service marks; or
385    
386     f) Requiring indemnification of licensors and authors of that
387     material by anyone who conveys the material (or modified versions of
388     it) with contractual assumptions of liability to the recipient, for
389     any liability that these contractual assumptions directly impose on
390     those licensors and authors.
391    
392     All other non-permissive additional terms are considered "further
393     restrictions" within the meaning of section 10. If the Program as you
394     received it, or any part of it, contains a notice stating that it is
395     governed by this License along with a term that is a further
396     restriction, you may remove that term. If a license document contains
397     a further restriction but permits relicensing or conveying under this
398     License, you may add to a covered work material governed by the terms
399     of that license document, provided that the further restriction does
400     not survive such relicensing or conveying.
401    
402     If you add terms to a covered work in accord with this section, you
403     must place, in the relevant source files, a statement of the
404     additional terms that apply to those files, or a notice indicating
405     where to find the applicable terms.
406    
407     Additional terms, permissive or non-permissive, may be stated in the
408     form of a separately written license, or stated as exceptions;
409     the above requirements apply either way.
410    
411     8. Termination.
412    
413     You may not propagate or modify a covered work except as expressly
414     provided under this License. Any attempt otherwise to propagate or
415     modify it is void, and will automatically terminate your rights under
416     this License (including any patent licenses granted under the third
417     paragraph of section 11).
418    
419     However, if you cease all violation of this License, then your
420     license from a particular copyright holder is reinstated (a)
421     provisionally, unless and until the copyright holder explicitly and
422     finally terminates your license, and (b) permanently, if the copyright
423     holder fails to notify you of the violation by some reasonable means
424     prior to 60 days after the cessation.
425    
426     Moreover, your license from a particular copyright holder is
427     reinstated permanently if the copyright holder notifies you of the
428     violation by some reasonable means, this is the first time you have
429     received notice of violation of this License (for any work) from that
430     copyright holder, and you cure the violation prior to 30 days after
431     your receipt of the notice.
432    
433     Termination of your rights under this section does not terminate the
434     licenses of parties who have received copies or rights from you under
435     this License. If your rights have been terminated and not permanently
436     reinstated, you do not qualify to receive new licenses for the same
437     material under section 10.
438    
439     9. Acceptance Not Required for Having Copies.
440    
441     You are not required to accept this License in order to receive or
442     run a copy of the Program. Ancillary propagation of a covered work
443     occurring solely as a consequence of using peer-to-peer transmission
444     to receive a copy likewise does not require acceptance. However,
445     nothing other than this License grants you permission to propagate or
446     modify any covered work. These actions infringe copyright if you do
447     not accept this License. Therefore, by modifying or propagating a
448     covered work, you indicate your acceptance of this License to do so.
449    
450     10. Automatic Licensing of Downstream Recipients.
451    
452     Each time you convey a covered work, the recipient automatically
453     receives a license from the original licensors, to run, modify and
454     propagate that work, subject to this License. You are not responsible
455     for enforcing compliance by third parties with this License.
456    
457     An "entity transaction" is a transaction transferring control of an
458     organization, or substantially all assets of one, or subdividing an
459     organization, or merging organizations. If propagation of a covered
460     work results from an entity transaction, each party to that
461     transaction who receives a copy of the work also receives whatever
462     licenses to the work the party's predecessor in interest had or could
463     give under the previous paragraph, plus a right to possession of the
464     Corresponding Source of the work from the predecessor in interest, if
465     the predecessor has it or can get it with reasonable efforts.
466    
467     You may not impose any further restrictions on the exercise of the
468     rights granted or affirmed under this License. For example, you may
469     not impose a license fee, royalty, or other charge for exercise of
470     rights granted under this License, and you may not initiate litigation
471     (including a cross-claim or counterclaim in a lawsuit) alleging that
472     any patent claim is infringed by making, using, selling, offering for
473     sale, or importing the Program or any portion of it.
474    
475     11. Patents.
476    
477     A "contributor" is a copyright holder who authorizes use under this
478     License of the Program or a work on which the Program is based. The
479     work thus licensed is called the contributor's "contributor version".
480    
481     A contributor's "essential patent claims" are all patent claims
482     owned or controlled by the contributor, whether already acquired or
483     hereafter acquired, that would be infringed by some manner, permitted
484     by this License, of making, using, or selling its contributor version,
485     but do not include claims that would be infringed only as a
486     consequence of further modification of the contributor version. For
487     purposes of this definition, "control" includes the right to grant
488     patent sublicenses in a manner consistent with the requirements of
489     this License.
490    
491     Each contributor grants you a non-exclusive, worldwide, royalty-free
492     patent license under the contributor's essential patent claims, to
493     make, use, sell, offer for sale, import and otherwise run, modify and
494     propagate the contents of its contributor version.
495    
496     In the following three paragraphs, a "patent license" is any express
497     agreement or commitment, however denominated, not to enforce a patent
498     (such as an express permission to practice a patent or covenant not to
499     sue for patent infringement). To "grant" such a patent license to a
500     party means to make such an agreement or commitment not to enforce a
501     patent against the party.
502    
503     If you convey a covered work, knowingly relying on a patent license,
504     and the Corresponding Source of the work is not available for anyone
505     to copy, free of charge and under the terms of this License, through a
506     publicly available network server or other readily accessible means,
507     then you must either (1) cause the Corresponding Source to be so
508     available, or (2) arrange to deprive yourself of the benefit of the
509     patent license for this particular work, or (3) arrange, in a manner
510     consistent with the requirements of this License, to extend the patent
511     license to downstream recipients. "Knowingly relying" means you have
512     actual knowledge that, but for the patent license, your conveying the
513     covered work in a country, or your recipient's use of the covered work
514     in a country, would infringe one or more identifiable patents in that
515     country that you have reason to believe are valid.
516    
517     If, pursuant to or in connection with a single transaction or
518     arrangement, you convey, or propagate by procuring conveyance of, a
519     covered work, and grant a patent license to some of the parties
520     receiving the covered work authorizing them to use, propagate, modify
521     or convey a specific copy of the covered work, then the patent license
522     you grant is automatically extended to all recipients of the covered
523     work and works based on it.
524    
525     A patent license is "discriminatory" if it does not include within
526     the scope of its coverage, prohibits the exercise of, or is
527     conditioned on the non-exercise of one or more of the rights that are
528     specifically granted under this License. You may not convey a covered
529     work if you are a party to an arrangement with a third party that is
530     in the business of distributing software, under which you make payment
531     to the third party based on the extent of your activity of conveying
532     the work, and under which the third party grants, to any of the
533     parties who would receive the covered work from you, a discriminatory
534     patent license (a) in connection with copies of the covered work
535     conveyed by you (or copies made from those copies), or (b) primarily
536     for and in connection with specific products or compilations that
537     contain the covered work, unless you entered into that arrangement,
538     or that patent license was granted, prior to 28 March 2007.
539    
540     Nothing in this License shall be construed as excluding or limiting
541     any implied license or other defenses to infringement that may
542     otherwise be available to you under applicable patent law.
543    
544     12. No Surrender of Others' Freedom.
545    
546     If conditions are imposed on you (whether by court order, agreement or
547     otherwise) that contradict the conditions of this License, they do not
548     excuse you from the conditions of this License. If you cannot convey a
549     covered work so as to satisfy simultaneously your obligations under this
550     License and any other pertinent obligations, then as a consequence you may
551     not convey it at all. For example, if you agree to terms that obligate you
552     to collect a royalty for further conveying from those to whom you convey
553     the Program, the only way you could satisfy both those terms and this
554     License would be to refrain entirely from conveying the Program.
555    
556     13. Use with the GNU Affero General Public License.
557    
558     Notwithstanding any other provision of this License, you have
559     permission to link or combine any covered work with a work licensed
560     under version 3 of the GNU Affero General Public License into a single
561     combined work, and to convey the resulting work. The terms of this
562     License will continue to apply to the part which is the covered work,
563     but the special requirements of the GNU Affero General Public License,
564     section 13, concerning interaction through a network will apply to the
565     combination as such.
566    
567     14. Revised Versions of this License.
568    
569     The Free Software Foundation may publish revised and/or new versions of
570     the GNU General Public License from time to time. Such new versions will
571     be similar in spirit to the present version, but may differ in detail to
572     address new problems or concerns.
573    
574     Each version is given a distinguishing version number. If the
575     Program specifies that a certain numbered version of the GNU General
576     Public License "or any later version" applies to it, you have the
577     option of following the terms and conditions either of that numbered
578     version or of any later version published by the Free Software
579     Foundation. If the Program does not specify a version number of the
580     GNU General Public License, you may choose any version ever published
581     by the Free Software Foundation.
582    
583     If the Program specifies that a proxy can decide which future
584     versions of the GNU General Public License can be used, that proxy's
585     public statement of acceptance of a version permanently authorizes you
586     to choose that version for the Program.
587    
588     Later license versions may give you additional or different
589     permissions. However, no additional obligations are imposed on any
590     author or copyright holder as a result of your choosing to follow a
591     later version.
592    
593     15. Disclaimer of Warranty.
594    
595     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
596     APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
597     HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
598     OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
599     THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
600     PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
601     IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
602     ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
603    
604     16. Limitation of Liability.
605    
606     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
607     WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
608     THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
609     GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
610     USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
611     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
612     PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
613     EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
614     SUCH DAMAGES.
615    
616     17. Interpretation of Sections 15 and 16.
617    
618     If the disclaimer of warranty and limitation of liability provided
619     above cannot be given local legal effect according to their terms,
620     reviewing courts shall apply local law that most closely approximates
621     an absolute waiver of all civil liability in connection with the
622     Program, unless a warranty or assumption of liability accompanies a
623     copy of the Program in return for a fee.
624    
625     END OF TERMS AND CONDITIONS
626    
627     How to Apply These Terms to Your New Programs
628    
629     If you develop a new program, and you want it to be of the greatest
630     possible use to the public, the best way to achieve this is to make it
631     free software which everyone can redistribute and change under these terms.
632    
633     To do so, attach the following notices to the program. It is safest
634     to attach them to the start of each source file to most effectively
635     state the exclusion of warranty; and each file should have at least
636     the "copyright" line and a pointer to where the full notice is found.
637    
638     <one line to give the program's name and a brief idea of what it does.>
639     Copyright (C) <year> <name of author>
640    
641     This program is free software: you can redistribute it and/or modify
642     it under the terms of the GNU General Public License as published by
643     the Free Software Foundation, either version 3 of the License, or
644     (at your option) any later version.
645    
646     This program is distributed in the hope that it will be useful,
647     but WITHOUT ANY WARRANTY; without even the implied warranty of
648     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
649     GNU General Public License for more details.
650    
651     You should have received a copy of the GNU General Public License
652     along with this program. If not, see <http://www.gnu.org/licenses/>.
653    
654     Also add information on how to contact you by electronic and paper mail.
655    
656     If the program does terminal interaction, make it output a short
657     notice like this when it starts in an interactive mode:
658    
659     <program> Copyright (C) <year> <name of author>
660     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
661     This is free software, and you are welcome to redistribute it
662     under certain conditions; type `show c' for details.
663    
664     The hypothetical commands `show w' and `show c' should show the appropriate
665     parts of the General Public License. Of course, your program's commands
666     might be different; for a GUI interface, you would use an "about box".
667    
668     You should also get your employer (if you work as a programmer) or school,
669     if any, to sign a "copyright disclaimer" for the program, if necessary.
670     For more information on this, and how to apply and follow the GNU GPL, see
671     <http://www.gnu.org/licenses/>.
672    
673     The GNU General Public License does not permit incorporating your program
674     into proprietary programs. If your program is a subroutine library, you
675     may consider it more useful to permit linking proprietary applications with
676     the library. If this is what you want to do, use the GNU Lesser General
677     Public License instead of this License. But first, please read
678     <http://www.gnu.org/philosophy/why-not-lgpl.html>.
