1 root 1.10 This program is released under the GPLv3 with the additional exemption that
2     compiling, linking, and/or using OpenSSL is allowed. You may provide
3     binary packages linked to the OpenSSL libraries, provided that all other
4     requirements of the GPL are met.

6 root 1.10 Some files in this package are licensed with different, but hopefully
7     compatible, licenses.

11     GNU GENERAL PUBLIC LICENSE
12     Version 3, 29 June 2007
13    
14     Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
15 pcg 1.1 Everyone is permitted to copy and distribute verbatim copies
16     of this license document, but changing it is not allowed.
17    
18 root 1.10 Preamble
19    
20     The GNU General Public License is a free, copyleft license for
21     software and other kinds of works.
22 pcg 1.1
23 root 1.10 The licenses for most software and other practical works are designed
24     to take away your freedom to share and change the works. By contrast,
25     the GNU General Public License is intended to guarantee your freedom to
26     share and change all versions of a program--to make sure it remains free
27     software for all its users. We, the Free Software Foundation, use the
28     GNU General Public License for most of our software; it applies also to
29     any other work released this way by its authors. You can apply it to
30 pcg 1.1 your programs, too.
31    
32     When we speak of free software, we are referring to freedom, not
33     price. Our General Public Licenses are designed to make sure that you
34     have the freedom to distribute copies of free software (and charge for
35 root 1.10 them if you wish), that you receive source code or can get it if you
36     want it, that you can change the software or use pieces of it in new
37     free programs, and that you know you can do these things.
38    
39     To protect your rights, we need to prevent others from denying you
40     these rights or asking you to surrender the rights. Therefore, you have
41     certain responsibilities if you distribute copies of the software, or if
42     you modify it: responsibilities to respect the freedom of others.
43 pcg 1.1
44     For example, if you distribute copies of such a program, whether
45 root 1.10 gratis or for a fee, you must pass on to the recipients the same
46     freedoms that you received. You must make sure that they, too, receive
47     or can get the source code. And you must show them these terms so they
48     know their rights.
49    
50     Developers that use the GNU GPL protect your rights with two steps:
51     (1) assert copyright on the software, and (2) offer you this License
52     giving you legal permission to copy, distribute and/or modify it.
53    
54     For the developers' and authors' protection, the GPL clearly explains
55     that there is no warranty for this free software. For both users' and
56     authors' sake, the GPL requires that modified versions be marked as
57     changed, so that their problems will not be attributed erroneously to
58     authors of previous versions.
59    
60     Some devices are designed to deny users access to install or run
61     modified versions of the software inside them, although the manufacturer
62     can do so. This is fundamentally incompatible with the aim of
63     protecting users' freedom to change the software. The systematic
64     pattern of such abuse occurs in the area of products for individuals to
65     use, which is precisely where it is most unacceptable. Therefore, we
66     have designed this version of the GPL to prohibit the practice for those
67     products. If such problems arise substantially in other domains, we
68     stand ready to extend this provision to those domains in future versions
69     of the GPL, as needed to protect the freedom of users.
70    
71     Finally, every program is threatened constantly by software patents.
72     States should not allow patents to restrict development and use of
73     software on general-purpose computers, but in those that do, we wish to
74     avoid the special danger that patents applied to a free program could
75     make it effectively proprietary. To prevent this, the GPL assures that
76     patents cannot be used to render the program non-free.
77 pcg 1.1
78     The precise terms and conditions for copying, distribution and
79     modification follow.
80 root 1.10
81     TERMS AND CONDITIONS
82    
83     0. Definitions.
84    
85     "This License" refers to version 3 of the GNU General Public License.
86    
87     "Copyright" also means copyright-like laws that apply to other kinds of
88     works, such as semiconductor masks.
89    
90     "The Program" refers to any copyrightable work licensed under this
91     License. Each licensee is addressed as "you". "Licensees" and
92     "recipients" may be individuals or organizations.
93    
94     To "modify" a work means to copy from or adapt all or part of the work
95     in a fashion requiring copyright permission, other than the making of an
96     exact copy. The resulting work is called a "modified version" of the
97     earlier work or a work "based on" the earlier work.
98    
99     A "covered work" means either the unmodified Program or a work based
100     on the Program.
101    
102     To "propagate" a work means to do anything with it that, without
103     permission, would make you directly or secondarily liable for
104     infringement under applicable copyright law, except executing it on a
105     computer or modifying a private copy. Propagation includes copying,
106     distribution (with or without modification), making available to the
107     public, and in some countries other activities as well.
108    
109     To "convey" a work means any kind of propagation that enables other
110     parties to make or receive copies. Mere interaction with a user through
111     a computer network, with no transfer of a copy, is not conveying.
112    
113     An interactive user interface displays "Appropriate Legal Notices"
114     to the extent that it includes a convenient and prominently visible
115     feature that (1) displays an appropriate copyright notice, and (2)
116     tells the user that there is no warranty for the work (except to the
117     extent that warranties are provided), that licensees may convey the
118     work under this License, and how to view a copy of this License. If
119     the interface presents a list of user commands or options, such as a
120     menu, a prominent item in the list meets this criterion.
121    
122     1. Source Code.
123    
124     The "source code" for a work means the preferred form of the work
125     for making modifications to it. "Object code" means any non-source
126     form of a work.
127    
128     A "Standard Interface" means an interface that either is an official
129     standard defined by a recognized standards body, or, in the case of
130     interfaces specified for a particular programming language, one that
131     is widely used among developers working in that language.
132    
133     The "System Libraries" of an executable work include anything, other
134     than the work as a whole, that (a) is included in the normal form of
135     packaging a Major Component, but which is not part of that Major
136     Component, and (b) serves only to enable use of the work with that
137     Major Component, or to implement a Standard Interface for which an
138     implementation is available to the public in source code form. A
139     "Major Component", in this context, means a major essential component
140     (kernel, window system, and so on) of the specific operating system
141     (if any) on which the executable work runs, or a compiler used to
142     produce the work, or an object code interpreter used to run it.
143    
144     The "Corresponding Source" for a work in object code form means all
145     the source code needed to generate, install, and (for an executable
146     work) run the object code and to modify the work, including scripts to
147     control those activities. However, it does not include the work's
148     System Libraries, or general-purpose tools or generally available free
149     programs which are used unmodified in performing those activities but
150     which are not part of the work. For example, Corresponding Source
151     includes interface definition files associated with source files for
152     the work, and the source code for shared libraries and dynamically
153     linked subprograms that the work is specifically designed to require,
154     such as by intimate data communication or control flow between those
155     subprograms and other parts of the work.
156    
157     The Corresponding Source need not include anything that users
158     can regenerate automatically from other parts of the Corresponding
159     Source.
160    
161     The Corresponding Source for a work in source code form is that
162     same work.
163    
164     2. Basic Permissions.
165    
166     All rights granted under this License are granted for the term of
167     copyright on the Program, and are irrevocable provided the stated
168     conditions are met. This License explicitly affirms your unlimited
169     permission to run the unmodified Program. The output from running a
170     covered work is covered by this License only if the output, given its
171     content, constitutes a covered work. This License acknowledges your
172     rights of fair use or other equivalent, as provided by copyright law.
173    
174     You may make, run and propagate covered works that you do not
175     convey, without conditions so long as your license otherwise remains
176     in force. You may convey covered works to others for the sole purpose
177     of having them make modifications exclusively for you, or provide you
178     with facilities for running those works, provided that you comply with
179     the terms of this License in conveying all material for which you do
180     not control copyright. Those thus making or running the covered works
181     for you must do so exclusively on your behalf, under your direction
182     and control, on terms that prohibit them from making any copies of
183     your copyrighted material outside their relationship with you.
184    
185     Conveying under any other circumstances is permitted solely under
186     the conditions stated below. Sublicensing is not allowed; section 10
187     makes it unnecessary.
188    
189     3. Protecting Users' Legal Rights From Anti-Circumvention Law.
190    
191     No covered work shall be deemed part of an effective technological
192     measure under any applicable law fulfilling obligations under article
193     11 of the WIPO copyright treaty adopted on 20 December 1996, or
194     similar laws prohibiting or restricting circumvention of such
195     measures.
196    
197     When you convey a covered work, you waive any legal power to forbid
198     circumvention of technological measures to the extent such circumvention
199     is effected by exercising rights under this License with respect to
200     the covered work, and you disclaim any intention to limit operation or
201     modification of the work as a means of enforcing, against the work's
202     users, your or third parties' legal rights to forbid circumvention of
203     technological measures.
204    
205     4. Conveying Verbatim Copies.
206    
207     You may convey verbatim copies of the Program's source code as you
208     receive it, in any medium, provided that you conspicuously and
209     appropriately publish on each copy an appropriate copyright notice;
210     keep intact all notices stating that this License and any
211     non-permissive terms added in accord with section 7 apply to the code;
212     keep intact all notices of the absence of any warranty; and give all
213     recipients a copy of this License along with the Program.
214    
215     You may charge any price or no price for each copy that you convey,
216     and you may offer support or warranty protection for a fee.
217    
218     5. Conveying Modified Source Versions.
219    
220     You may convey a work based on the Program, or the modifications to
221     produce it from the Program, in the form of source code under the
222     terms of section 4, provided that you also meet all of these conditions:
223    
224     a) The work must carry prominent notices stating that you modified
225     it, and giving a relevant date.
226    
227     b) The work must carry prominent notices stating that it is
228     released under this License and any conditions added under section
229     7. This requirement modifies the requirement in section 4 to
230     "keep intact all notices".
231    
232     c) You must license the entire work, as a whole, under this
233     License to anyone who comes into possession of a copy. This
234     License will therefore apply, along with any applicable section 7
235     additional terms, to the whole of the work, and all its parts,
236     regardless of how they are packaged. This License gives no
237     permission to license the work in any other way, but it does not
238     invalidate such permission if you have separately received it.
239    
240     d) If the work has interactive user interfaces, each must display
241     Appropriate Legal Notices; however, if the Program has interactive
242     interfaces that do not display Appropriate Legal Notices, your
243     work need not make them do so.
244    
245     A compilation of a covered work with other separate and independent
246     works, which are not by their nature extensions of the covered work,
247     and which are not combined with it such as to form a larger program,
248     in or on a volume of a storage or distribution medium, is called an
249     "aggregate" if the compilation and its resulting copyright are not
250     used to limit the access or legal rights of the compilation's users
251     beyond what the individual works permit. Inclusion of a covered work
252     in an aggregate does not cause this License to apply to the other
253     parts of the aggregate.
254    
255     6. Conveying Non-Source Forms.
256    
257     You may convey a covered work in object code form under the terms
258     of sections 4 and 5, provided that you also convey the
259     machine-readable Corresponding Source under the terms of this License,
260     in one of these ways:
261    
262     a) Convey the object code in, or embodied in, a physical product
263     (including a physical distribution medium), accompanied by the
264     Corresponding Source fixed on a durable physical medium
265     customarily used for software interchange.
266    
267     b) Convey the object code in, or embodied in, a physical product
268     (including a physical distribution medium), accompanied by a
269     written offer, valid for at least three years and valid for as
270     long as you offer spare parts or customer support for that product
271     model, to give anyone who possesses the object code either (1) a
272     copy of the Corresponding Source for all the software in the
273     product that is covered by this License, on a durable physical
274     medium customarily used for software interchange, for a price no
275     more than your reasonable cost of physically performing this
276     conveying of source, or (2) access to copy the
277     Corresponding Source from a network server at no charge.
278    
279     c) Convey individual copies of the object code with a copy of the
280     written offer to provide the Corresponding Source. This
281     alternative is allowed only occasionally and noncommercially, and
282     only if you received the object code with such an offer, in accord
283     with subsection 6b.
284    
285     d) Convey the object code by offering access from a designated
286     place (gratis or for a charge), and offer equivalent access to the
287     Corresponding Source in the same way through the same place at no
288     further charge. You need not require recipients to copy the
289     Corresponding Source along with the object code. If the place to
290     copy the object code is a network server, the Corresponding Source
291     may be on a different server (operated by you or a third party)
292     that supports equivalent copying facilities, provided you maintain
293     clear directions next to the object code saying where to find the
294     Corresponding Source. Regardless of what server hosts the
295     Corresponding Source, you remain obligated to ensure that it is
296     available for as long as needed to satisfy these requirements.
297    
298     e) Convey the object code using peer-to-peer transmission, provided
299     you inform other peers where the object code and Corresponding
300     Source of the work are being offered to the general public at no
301     charge under subsection 6d.
302    
303     A separable portion of the object code, whose source code is excluded
304     from the Corresponding Source as a System Library, need not be
305     included in conveying the object code work.
306    
307     A "User Product" is either (1) a "consumer product", which means any
308     tangible personal property which is normally used for personal, family,
309     or household purposes, or (2) anything designed or sold for incorporation
310     into a dwelling. In determining whether a product is a consumer product,
311     doubtful cases shall be resolved in favor of coverage. For a particular
312     product received by a particular user, "normally used" refers to a
313     typical or common use of that class of product, regardless of the status
314     of the particular user or of the way in which the particular user
315     actually uses, or expects or is expected to use, the product. A product
316     is a consumer product regardless of whether the product has substantial
317     commercial, industrial or non-consumer uses, unless such uses represent
318     the only significant mode of use of the product.
319    
320     "Installation Information" for a User Product means any methods,
321     procedures, authorization keys, or other information required to install
322     and execute modified versions of a covered work in that User Product from
323     a modified version of its Corresponding Source. The information must
324     suffice to ensure that the continued functioning of the modified object
325     code is in no case prevented or interfered with solely because
326     modification has been made.
327    
328     If you convey an object code work under this section in, or with, or
329     specifically for use in, a User Product, and the conveying occurs as
330     part of a transaction in which the right of possession and use of the
331     User Product is transferred to the recipient in perpetuity or for a
332     fixed term (regardless of how the transaction is characterized), the
333     Corresponding Source conveyed under this section must be accompanied
334     by the Installation Information. But this requirement does not apply
335     if neither you nor any third party retains the ability to install
336     modified object code on the User Product (for example, the work has
337     been installed in ROM).
338    
339     The requirement to provide Installation Information does not include a
340     requirement to continue to provide support service, warranty, or updates
341     for a work that has been modified or installed by the recipient, or for
342     the User Product in which it has been modified or installed. Access to a
343     network may be denied when the modification itself materially and
344     adversely affects the operation of the network or violates the rules and
345     protocols for communication across the network.
346    
347     Corresponding Source conveyed, and Installation Information provided,
348     in accord with this section must be in a format that is publicly
349     documented (and with an implementation available to the public in
350     source code form), and must require no special password or key for
351     unpacking, reading or copying.
352    
353     7. Additional Terms.
354    
355     "Additional permissions" are terms that supplement the terms of this
356     License by making exceptions from one or more of its conditions.
357     Additional permissions that are applicable to the entire Program shall
358     be treated as though they were included in this License, to the extent
359     that they are valid under applicable law. If additional permissions
360     apply only to part of the Program, that part may be used separately
361     under those permissions, but the entire Program remains governed by
362     this License without regard to the additional permissions.
363    
364     When you convey a copy of a covered work, you may at your option
365     remove any additional permissions from that copy, or from any part of
366     it. (Additional permissions may be written to require their own
367     removal in certain cases when you modify the work.) You may place
368     additional permissions on material, added by you to a covered work,
369     for which you have or can give appropriate copyright permission.
370    
371     Notwithstanding any other provision of this License, for material you
372     add to a covered work, you may (if authorized by the copyright holders of
373     that material) supplement the terms of this License with terms:
374    
375     a) Disclaiming warranty or limiting liability differently from the
376     terms of sections 15 and 16 of this License; or
377    
378     b) Requiring preservation of specified reasonable legal notices or
379     author attributions in that material or in the Appropriate Legal
380     Notices displayed by works containing it; or
381    
382     c) Prohibiting misrepresentation of the origin of that material, or
383     requiring that modified versions of such material be marked in
384     reasonable ways as different from the original version; or
385    
386     d) Limiting the use for publicity purposes of names of licensors or
387     authors of the material; or
388    
389     e) Declining to grant rights under trademark law for use of some
390     trade names, trademarks, or service marks; or
391    
392     f) Requiring indemnification of licensors and authors of that
393     material by anyone who conveys the material (or modified versions of
394     it) with contractual assumptions of liability to the recipient, for
395     any liability that these contractual assumptions directly impose on
396     those licensors and authors.
397    
398     All other non-permissive additional terms are considered "further
399     restrictions" within the meaning of section 10. If the Program as you
400     received it, or any part of it, contains a notice stating that it is
401     governed by this License along with a term that is a further
402     restriction, you may remove that term. If a license document contains
403     a further restriction but permits relicensing or conveying under this
404     License, you may add to a covered work material governed by the terms
405     of that license document, provided that the further restriction does
406     not survive such relicensing or conveying.
407    
408     If you add terms to a covered work in accord with this section, you
409     must place, in the relevant source files, a statement of the
410     additional terms that apply to those files, or a notice indicating
411     where to find the applicable terms.
412    
413     Additional terms, permissive or non-permissive, may be stated in the
414     form of a separately written license, or stated as exceptions;
415     the above requirements apply either way.
416    
417     8. Termination.
418    
419     You may not propagate or modify a covered work except as expressly
420     provided under this License. Any attempt otherwise to propagate or
421     modify it is void, and will automatically terminate your rights under
422     this License (including any patent licenses granted under the third
423     paragraph of section 11).
424    
425     However, if you cease all violation of this License, then your
426     license from a particular copyright holder is reinstated (a)
427     provisionally, unless and until the copyright holder explicitly and
428     finally terminates your license, and (b) permanently, if the copyright
429     holder fails to notify you of the violation by some reasonable means
430     prior to 60 days after the cessation.
431    
432     Moreover, your license from a particular copyright holder is
433     reinstated permanently if the copyright holder notifies you of the
434     violation by some reasonable means, this is the first time you have
435     received notice of violation of this License (for any work) from that
436     copyright holder, and you cure the violation prior to 30 days after
437     your receipt of the notice.
438    
439     Termination of your rights under this section does not terminate the
440     licenses of parties who have received copies or rights from you under
441     this License. If your rights have been terminated and not permanently
442     reinstated, you do not qualify to receive new licenses for the same
443     material under section 10.
444    
445     9. Acceptance Not Required for Having Copies.
446    
447     You are not required to accept this License in order to receive or
448     run a copy of the Program. Ancillary propagation of a covered work
449     occurring solely as a consequence of using peer-to-peer transmission
450     to receive a copy likewise does not require acceptance. However,
451     nothing other than this License grants you permission to propagate or
452     modify any covered work. These actions infringe copyright if you do
453     not accept this License. Therefore, by modifying or propagating a
454     covered work, you indicate your acceptance of this License to do so.
455    
456     10. Automatic Licensing of Downstream Recipients.
457    
458     Each time you convey a covered work, the recipient automatically
459     receives a license from the original licensors, to run, modify and
460     propagate that work, subject to this License. You are not responsible
461     for enforcing compliance by third parties with this License.
462    
463     An "entity transaction" is a transaction transferring control of an
464     organization, or substantially all assets of one, or subdividing an
465     organization, or merging organizations. If propagation of a covered
466     work results from an entity transaction, each party to that
467     transaction who receives a copy of the work also receives whatever
468     licenses to the work the party's predecessor in interest had or could
469     give under the previous paragraph, plus a right to possession of the
470     Corresponding Source of the work from the predecessor in interest, if
471     the predecessor has it or can get it with reasonable efforts.
472    
473     You may not impose any further restrictions on the exercise of the
474     rights granted or affirmed under this License. For example, you may
475     not impose a license fee, royalty, or other charge for exercise of
476     rights granted under this License, and you may not initiate litigation
477     (including a cross-claim or counterclaim in a lawsuit) alleging that
478     any patent claim is infringed by making, using, selling, offering for
479     sale, or importing the Program or any portion of it.
480    
481     11. Patents.
482    
483     A "contributor" is a copyright holder who authorizes use under this
484     License of the Program or a work on which the Program is based. The
485     work thus licensed is called the contributor's "contributor version".
486    
487     A contributor's "essential patent claims" are all patent claims
488     owned or controlled by the contributor, whether already acquired or
489     hereafter acquired, that would be infringed by some manner, permitted
490     by this License, of making, using, or selling its contributor version,
491     but do not include claims that would be infringed only as a
492     consequence of further modification of the contributor version. For
493     purposes of this definition, "control" includes the right to grant
494     patent sublicenses in a manner consistent with the requirements of
495 pcg 1.1 this License.
496    
497 root 1.10 Each contributor grants you a non-exclusive, worldwide, royalty-free
498     patent license under the contributor's essential patent claims, to
499     make, use, sell, offer for sale, import and otherwise run, modify and
500     propagate the contents of its contributor version.
501    
502     In the following three paragraphs, a "patent license" is any express
503     agreement or commitment, however denominated, not to enforce a patent
504     (such as an express permission to practice a patent or covenant not to
505     sue for patent infringement). To "grant" such a patent license to a
506     party means to make such an agreement or commitment not to enforce a
507     patent against the party.
508    
509     If you convey a covered work, knowingly relying on a patent license,
510     and the Corresponding Source of the work is not available for anyone
511     to copy, free of charge and under the terms of this License, through a
512     publicly available network server or other readily accessible means,
513     then you must either (1) cause the Corresponding Source to be so
514     available, or (2) arrange to deprive yourself of the benefit of the
515     patent license for this particular work, or (3) arrange, in a manner
516     consistent with the requirements of this License, to extend the patent
517     license to downstream recipients. "Knowingly relying" means you have
518     actual knowledge that, but for the patent license, your conveying the
519     covered work in a country, or your recipient's use of the covered work
520     in a country, would infringe one or more identifiable patents in that
521     country that you have reason to believe are valid.
522    
523     If, pursuant to or in connection with a single transaction or
524     arrangement, you convey, or propagate by procuring conveyance of, a
525     covered work, and grant a patent license to some of the parties
526     receiving the covered work authorizing them to use, propagate, modify
527     or convey a specific copy of the covered work, then the patent license
528     you grant is automatically extended to all recipients of the covered
529     work and works based on it.
530    
531     A patent license is "discriminatory" if it does not include within
532     the scope of its coverage, prohibits the exercise of, or is
533     conditioned on the non-exercise of one or more of the rights that are
534     specifically granted under this License. You may not convey a covered
535     work if you are a party to an arrangement with a third party that is
536     in the business of distributing software, under which you make payment
537     to the third party based on the extent of your activity of conveying
538     the work, and under which the third party grants, to any of the
539     parties who would receive the covered work from you, a discriminatory
540     patent license (a) in connection with copies of the covered work
541     conveyed by you (or copies made from those copies), or (b) primarily
542     for and in connection with specific products or compilations that
543     contain the covered work, unless you entered into that arrangement,
544     or that patent license was granted, prior to 28 March 2007.
545    
546     Nothing in this License shall be construed as excluding or limiting
547     any implied license or other defenses to infringement that may
548     otherwise be available to you under applicable patent law.
549    
550     12. No Surrender of Others' Freedom.
551    
552     If conditions are imposed on you (whether by court order, agreement or
553 pcg 1.1 otherwise) that contradict the conditions of this License, they do not
554 root 1.10 excuse you from the conditions of this License. If you cannot convey a
555     covered work so as to satisfy simultaneously your obligations under this
556     License and any other pertinent obligations, then as a consequence you may
557     not convey it at all. For example, if you agree to terms that obligate you
558     to collect a royalty for further conveying from those to whom you convey
559     the Program, the only way you could satisfy both those terms and this
560     License would be to refrain entirely from conveying the Program.
561    
562     13. Use with the GNU Affero General Public License.
563    
564     Notwithstanding any other provision of this License, you have
565     permission to link or combine any covered work with a work licensed
566     under version 3 of the GNU Affero General Public License into a single
567     combined work, and to convey the resulting work. The terms of this
568     License will continue to apply to the part which is the covered work,
569     but the special requirements of the GNU Affero General Public License,
570     section 13, concerning interaction through a network will apply to the
571     combination as such.
572    
573     14. Revised Versions of this License.
574 pcg 1.1
575 root 1.10 The Free Software Foundation may publish revised and/or new versions of
576     the GNU General Public License from time to time. Such new versions will
577 pcg 1.1 be similar in spirit to the present version, but may differ in detail to
578     address new problems or concerns.
579    
580 root 1.10 Each version is given a distinguishing version number. If the
581     Program specifies that a certain numbered version of the GNU General
582     Public License "or any later version" applies to it, you have the
583     option of following the terms and conditions either of that numbered
584     version or of any later version published by the Free Software
585     Foundation. If the Program does not specify a version number of the
586     GNU General Public License, you may choose any version ever published
587     by the Free Software Foundation.
588    
589     If the Program specifies that a proxy can decide which future
590     versions of the GNU General Public License can be used, that proxy's
591     public statement of acceptance of a version permanently authorizes you
592     to choose that version for the Program.
593    
594     Later license versions may give you additional or different
595     permissions. However, no additional obligations are imposed on any
596     author or copyright holder as a result of your choosing to follow a
597     later version.
598    
599     15. Disclaimer of Warranty.
600    
601     THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
602     APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
603     HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
604     OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
605     THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
606     PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
607     IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
608     ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
609    
610     16. Limitation of Liability.
611    
612     IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
613     WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
614     THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
615     GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
616     USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
617     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
618     PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
619     EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
620     SUCH DAMAGES.
621    
622     17. Interpretation of Sections 15 and 16.
623    
624     If the disclaimer of warranty and limitation of liability provided
625     above cannot be given local legal effect according to their terms,
626     reviewing courts shall apply local law that most closely approximates
627     an absolute waiver of all civil liability in connection with the
628     Program, unless a warranty or assumption of liability accompanies a
629     copy of the Program in return for a fee.
630    
631     END OF TERMS AND CONDITIONS
632    
633     How to Apply These Terms to Your New Programs
634 pcg 1.1
635     If you develop a new program, and you want it to be of the greatest
636     possible use to the public, the best way to achieve this is to make it
637     free software which everyone can redistribute and change under these terms.
638    
639     To do so, attach the following notices to the program. It is safest
640     to attach them to the start of each source file to most effectively
641 root 1.10 state the exclusion of warranty; and each file should have at least
642 pcg 1.1 the "copyright" line and a pointer to where the full notice is found.
643    
644     <one line to give the program's name and a brief idea of what it does.>
645 pcg 1.2 Copyright (C) <year> <name of author>
646 pcg 1.1
647 root 1.10 This program is free software: you can redistribute it and/or modify
648 pcg 1.1 it under the terms of the GNU General Public License as published by
649 root 1.10 the Free Software Foundation, either version 3 of the License, or
650 pcg 1.1 (at your option) any later version.
651    
652     This program is distributed in the hope that it will be useful,
653     but WITHOUT ANY WARRANTY; without even the implied warranty of
654     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
655     GNU General Public License for more details.
656    
657     You should have received a copy of the GNU General Public License
658 root 1.10 along with this program. If not, see <http://www.gnu.org/licenses/>.
659 pcg 1.1
660     Also add information on how to contact you by electronic and paper mail.
661    
662 root 1.10 If the program does terminal interaction, make it output a short
663     notice like this when it starts in an interactive mode:
664 pcg 1.1
665 root 1.10 <program> Copyright (C) <year> <name of author>
666     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
667 pcg 1.1 This is free software, and you are welcome to redistribute it
668     under certain conditions; type `show c' for details.
669    
670     The hypothetical commands `show w' and `show c' should show the appropriate
671 root 1.10 parts of the General Public License. Of course, your program's commands
672     might be different; for a GUI interface, you would use an "about box".
673    
674     You should also get your employer (if you work as a programmer) or school,
675     if any, to sign a "copyright disclaimer" for the program, if necessary.
676     For more information on this, and how to apply and follow the GNU GPL, see
677     <http://www.gnu.org/licenses/>.
678    
679     The GNU General Public License does not permit incorporating your program
680     into proprietary programs. If your program is a subroutine library, you
681     may consider it more useful to permit linking proprietary applications with
682     the library. If this is what you want to do, use the GNU Lesser General
683     Public License instead of this License. But first, please read
684     <http://www.gnu.org/philosophy/why-not-lgpl.html>.
