12 GNU LESSER GENERAL PUBLIC LICENSE
13 Version 3, 29 June 2007
14
15 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
16 Everyone is permitted to copy and distribute verbatim copies
17 of this license document, but changing it is not allowed.
18
19
20 This version of the GNU Lesser General Public License incorporates
21the terms and conditions of version 3 of the GNU General Public
22License, supplemented by the additional permissions listed below.
23
24 0. Additional Definitions.
25
26 As used herein, "this License" refers to version 3 of the GNU Lesser
27General Public License, and the "GNU GPL" refers to version 3 of the GNU
28General Public License.
29
30 "The Library" refers to a covered work governed by this License,
31other than an Application or a Combined Work as defined below.
32
33 An "Application" is any work that makes use of an interface provided
34by the Library, but which is not otherwise based on the Library.
35Defining a subclass of a class defined by the Library is deemed a mode
36of using an interface provided by the Library.
37
38 A "Combined Work" is a work produced by combining or linking an
39Application with the Library. The particular version of the Library
40with which the Combined Work was made is also called the "Linked
41Version".
42
43 The "Minimal Corresponding Source" for a Combined Work means the
44Corresponding Source for the Combined Work, excluding any source code
45for portions of the Combined Work that, considered in isolation, are
46based on the Application, and not on the Linked Version.
47
48 The "Corresponding Application Code" for a Combined Work means the
49object code and/or source code for the Application, including any data
50and utility programs needed for reproducing the Combined Work from the
51Application, but excluding the System Libraries of the Combined Work.
52
53 1. Exception to Section 3 of the GNU GPL.
54
55 You may convey a covered work under sections 3 and 4 of this License
56without being bound by section 3 of the GNU GPL.
57
58 2. Conveying Modified Versions.
59
60 If you modify a copy of the Library, and, in your modifications, a
61facility refers to a function or data to be supplied by an Application
62that uses the facility (other than as an argument passed when the
63facility is invoked), then you may convey a copy of the modified
64version:
65
66 a) under this License, provided that you make a good faith effort to
67 ensure that, in the event an Application does not supply the
68 function or data, the facility still operates, and performs
69 whatever part of its purpose remains meaningful, or
70
71 b) under the GNU GPL, with none of the additional permissions of
72 this License applicable to that copy.
73
74 3. Object Code Incorporating Material from Library Header Files.
75
76 The object code form of an Application may incorporate material from
77a header file that is part of the Library. You may convey such object
78code under terms of your choice, provided that, if the incorporated
79material is not limited to numerical parameters, data structure
80layouts and accessors, or small macros, inline functions and templates
81(ten or fewer lines in length), you do both of the following:
82
83 a) Give prominent notice with each copy of the object code that the
84 Library is used in it and that the Library and its use are
85 covered by this License.
86
87 b) Accompany the object code with a copy of the GNU GPL and this license
88 document.
89
90 4. Combined Works.
91
92 You may convey a Combined Work under terms of your choice that,
93taken together, effectively do not restrict modification of the
94portions of the Library contained in the Combined Work and reverse
95engineering for debugging such modifications, if you also do each of
96the following:
97
98 a) Give prominent notice with each copy of the Combined Work that
99 the Library is used in it and that the Library and its use are
100 covered by this License.
101
102 b) Accompany the Combined Work with a copy of the GNU GPL and this license
103 document.
104
105 c) For a Combined Work that displays copyright notices during
106 execution, include the copyright notice for the Library among
107 these notices, as well as a reference directing the user to the
108 copies of the GNU GPL and this license document.
109
110 d) Do one of the following:
111
112 0) Convey the Minimal Corresponding Source under the terms of this
113 License, and the Corresponding Application Code in a form
114 suitable for, and under terms that permit, the user to
115 recombine or relink the Application with a modified version of
116 the Linked Version to produce a modified Combined Work, in the
117 manner specified by section 6 of the GNU GPL for conveying
118 Corresponding Source.
119
120 1) Use a suitable shared library mechanism for linking with the
121 Library. A suitable mechanism is one that (a) uses at run time
122 a copy of the Library already present on the user's computer
123 system, and (b) will operate properly with a modified version
124 of the Library that is interface-compatible with the Linked
125 Version.
126
127 e) Provide Installation Information, but only if you would otherwise
128 be required to provide such information under section 6 of the
129 GNU GPL, and only to the extent that such information is
130 necessary to install and execute a modified version of the
131 Combined Work produced by recombining or relinking the
132 Application with a modified version of the Linked Version. (If
133 you use option 4d0, the Installation Information must accompany
134 the Minimal Corresponding Source and Corresponding Application
135 Code. If you use option 4d1, you must provide the Installation
136 Information in the manner specified by section 6 of the GNU GPL
137 for conveying Corresponding Source.)
138
139 5. Combined Libraries.
140
141 You may place library facilities that are a work based on the
142Library side by side in a single library together with other library
143facilities that are not Applications and are not covered by this
144License, and convey such a combined library under terms of your
145choice, if you do both of the following:
146
147 a) Accompany the combined library with a copy of the same work based
148 on the Library, uncombined with any other library facilities,
149 conveyed under the terms of this License.
150
151 b) Give prominent notice with the combined library that part of it
152 is a work based on the Library, and explaining where to find the
153 accompanying uncombined form of the same work.
154
155 6. Revised Versions of the GNU Lesser General Public License.
156
157 The Free Software Foundation may publish revised and/or new versions
158of the GNU Lesser General Public License from time to time. Such new
159versions will be similar in spirit to the present version, but may
160differ in detail to address new problems or concerns.
161
162 Each version is given a distinguishing version number. If the
163Library as you received it specifies that a certain numbered version
164of the GNU Lesser General Public License "or any later version"
165applies to it, you have the option of following the terms and
166conditions either of that published version or of any later version
167published by the Free Software Foundation. If the Library as you
168received it does not specify a version number of the GNU Lesser
169General Public License, you may choose any version of the GNU Lesser
170General Public License ever published by the Free Software Foundation.
171
172 If the Library as you received it specifies that a proxy can decide
173whether future versions of the GNU Lesser General Public License shall
174apply, that proxy's public statement of acceptance of any version is
175permanent authorization for you to choose that version for the
176Library.

624ce48e
KL
184
185 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
186 Everyone is permitted to copy and distribute verbatim copies
187 of this license document, but changing it is not allowed.
188
9b1afdde 189 Preamble
624ce48e
KL
190
191 The GNU General Public License is a free, copyleft license for
192software and other kinds of works.
193
194 The licenses for most software and other practical works are designed
195to take away your freedom to share and change the works. By contrast,
196the GNU General Public License is intended to guarantee your freedom to
197share and change all versions of a program--to make sure it remains free
198software for all its users. We, the Free Software Foundation, use the
199GNU General Public License for most of our software; it applies also to
200any other work released this way by its authors. You can apply it to
201your programs, too.
202
203 When we speak of free software, we are referring to freedom, not
204price. Our General Public Licenses are designed to make sure that you
205have the freedom to distribute copies of free software (and charge for
206them if you wish), that you receive source code or can get it if you
207want it, that you can change the software or use pieces of it in new
208free programs, and that you know you can do these things.
209
210 To protect your rights, we need to prevent others from denying you
211these rights or asking you to surrender the rights. Therefore, you have
212certain responsibilities if you distribute copies of the software, or if
213you modify it: responsibilities to respect the freedom of others.
214
215 For example, if you distribute copies of such a program, whether
216gratis or for a fee, you must pass on to the recipients the same
217freedoms that you received. You must make sure that they, too, receive
218or can get the source code. And you must show them these terms so they
219know their rights.
220
221 Developers that use the GNU GPL protect your rights with two steps:
222(1) assert copyright on the software, and (2) offer you this License
223giving you legal permission to copy, distribute and/or modify it.
224
225 For the developers' and authors' protection, the GPL clearly explains
226that there is no warranty for this free software. For both users' and
227authors' sake, the GPL requires that modified versions be marked as
228changed, so that their problems will not be attributed erroneously to
229authors of previous versions.
230
231 Some devices are designed to deny users access to install or run
232modified versions of the software inside them, although the manufacturer
233can do so. This is fundamentally incompatible with the aim of
234protecting users' freedom to change the software. The systematic
235pattern of such abuse occurs in the area of products for individuals to
236use, which is precisely where it is most unacceptable. Therefore, we
237have designed this version of the GPL to prohibit the practice for those
238products. If such problems arise substantially in other domains, we
239stand ready to extend this provision to those domains in future versions
240of the GPL, as needed to protect the freedom of users.
241
242 Finally, every program is threatened constantly by software patents.
243States should not allow patents to restrict development and use of
244software on general-purpose computers, but in those that do, we wish to
245avoid the special danger that patents applied to a free program could
246make it effectively proprietary. To prevent this, the GPL assures that
247patents cannot be used to render the program non-free.
248
249 The precise terms and conditions for copying, distribution and
250modification follow.
251
9b1afdde 252 TERMS AND CONDITIONS
624ce48e
KL
253
254 0. Definitions.
255
256 "This License" refers to version 3 of the GNU General Public License.
257
258 "Copyright" also means copyright-like laws that apply to other kinds of
259works, such as semiconductor masks.
260
261 "The Program" refers to any copyrightable work licensed under this
262License. Each licensee is addressed as "you". "Licensees" and
263"recipients" may be individuals or organizations.
264
265 To "modify" a work means to copy from or adapt all or part of the work
266in a fashion requiring copyright permission, other than the making of an
267exact copy. The resulting work is called a "modified version" of the
268earlier work or a work "based on" the earlier work.
269
270 A "covered work" means either the unmodified Program or a work based
271on the Program.
272
273 To "propagate" a work means to do anything with it that, without
274permission, would make you directly or secondarily liable for
275infringement under applicable copyright law, except executing it on a
276computer or modifying a private copy. Propagation includes copying,
277distribution (with or without modification), making available to the
278public, and in some countries other activities as well.
279
280 To "convey" a work means any kind of propagation that enables other
281parties to make or receive copies. Mere interaction with a user through
282a computer network, with no transfer of a copy, is not conveying.
283
284 An interactive user interface displays "Appropriate Legal Notices"
285to the extent that it includes a convenient and prominently visible
286feature that (1) displays an appropriate copyright notice, and (2)
287tells the user that there is no warranty for the work (except to the
288extent that warranties are provided), that licensees may convey the
289work under this License, and how to view a copy of this License. If
290the interface presents a list of user commands or options, such as a
291menu, a prominent item in the list meets this criterion.
292
293 1. Source Code.
294
295 The "source code" for a work means the preferred form of the work
296for making modifications to it. "Object code" means any non-source
297form of a work.
298
299 A "Standard Interface" means an interface that either is an official
300standard defined by a recognized standards body, or, in the case of
301interfaces specified for a particular programming language, one that
302is widely used among developers working in that language.
303
304 The "System Libraries" of an executable work include anything, other
305than the work as a whole, that (a) is included in the normal form of
306packaging a Major Component, but which is not part of that Major
307Component, and (b) serves only to enable use of the work with that
308Major Component, or to implement a Standard Interface for which an
309implementation is available to the public in source code form. A
310"Major Component", in this context, means a major essential component
311(kernel, window system, and so on) of the specific operating system
312(if any) on which the executable work runs, or a compiler used to
313produce the work, or an object code interpreter used to run it.
314
315 The "Corresponding Source" for a work in object code form means all
316the source code needed to generate, install, and (for an executable
317work) run the object code and to modify the work, including scripts to
318control those activities. However, it does not include the work's
319System Libraries, or general-purpose tools or generally available free
320programs which are used unmodified in performing those activities but
321which are not part of the work. For example, Corresponding Source
322includes interface definition files associated with source files for
323the work, and the source code for shared libraries and dynamically
324linked subprograms that the work is specifically designed to require,
325such as by intimate data communication or control flow between those
326subprograms and other parts of the work.
327
328 The Corresponding Source need not include anything that users
329can regenerate automatically from other parts of the Corresponding
330Source.
331
332 The Corresponding Source for a work in source code form is that
333same work.
334
335 2. Basic Permissions.
336
337 All rights granted under this License are granted for the term of
338copyright on the Program, and are irrevocable provided the stated
339conditions are met. This License explicitly affirms your unlimited
340permission to run the unmodified Program. The output from running a
341covered work is covered by this License only if the output, given its
342content, constitutes a covered work. This License acknowledges your
343rights of fair use or other equivalent, as provided by copyright law.
344
345 You may make, run and propagate covered works that you do not
346convey, without conditions so long as your license otherwise remains
347in force. You may convey covered works to others for the sole purpose
348of having them make modifications exclusively for you, or provide you
349with facilities for running those works, provided that you comply with
350the terms of this License in conveying all material for which you do
351not control copyright. Those thus making or running the covered works
352for you must do so exclusively on your behalf, under your direction
353and control, on terms that prohibit them from making any copies of
354your copyrighted material outside their relationship with you.
355
356 Conveying under any other circumstances is permitted solely under
357the conditions stated below. Sublicensing is not allowed; section 10
358makes it unnecessary.
359
360 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
361
362 No covered work shall be deemed part of an effective technological
363measure under any applicable law fulfilling obligations under article
36411 of the WIPO copyright treaty adopted on 20 December 1996, or
365similar laws prohibiting or restricting circumvention of such
366measures.
367
368 When you convey a covered work, you waive any legal power to forbid
369circumvention of technological measures to the extent such circumvention
370is effected by exercising rights under this License with respect to
371the covered work, and you disclaim any intention to limit operation or
372modification of the work as a means of enforcing, against the work's
373users, your or third parties' legal rights to forbid circumvention of
374technological measures.
375
376 4. Conveying Verbatim Copies.
377
378 You may convey verbatim copies of the Program's source code as you
379receive it, in any medium, provided that you conspicuously and
380appropriately publish on each copy an appropriate copyright notice;
381keep intact all notices stating that this License and any
382non-permissive terms added in accord with section 7 apply to the code;
383keep intact all notices of the absence of any warranty; and give all
384recipients a copy of this License along with the Program.
385
386 You may charge any price or no price for each copy that you convey,
387and you may offer support or warranty protection for a fee.
388
389 5. Conveying Modified Source Versions.
390
391 You may convey a work based on the Program, or the modifications to
392produce it from the Program, in the form of source code under the
393terms of section 4, provided that you also meet all of these conditions:
394
395 a) The work must carry prominent notices stating that you modified
396 it, and giving a relevant date.
397
398 b) The work must carry prominent notices stating that it is
399 released under this License and any conditions added under section
400 7. This requirement modifies the requirement in section 4 to
401 "keep intact all notices".
402
403 c) You must license the entire work, as a whole, under this
404 License to anyone who comes into possession of a copy. This
405 License will therefore apply, along with any applicable section 7
406 additional terms, to the whole of the work, and all its parts,
407 regardless of how they are packaged. This License gives no
408 permission to license the work in any other way, but it does not
409 invalidate such permission if you have separately received it.
410
411 d) If the work has interactive user interfaces, each must display
412 Appropriate Legal Notices; however, if the Program has interactive
413 interfaces that do not display Appropriate Legal Notices, your
414 work need not make them do so.
415
416 A compilation of a covered work with other separate and independent
417works, which are not by their nature extensions of the covered work,
418and which are not combined with it such as to form a larger program,
419in or on a volume of a storage or distribution medium, is called an
420"aggregate" if the compilation and its resulting copyright are not
421used to limit the access or legal rights of the compilation's users
422beyond what the individual works permit. Inclusion of a covered work
423in an aggregate does not cause this License to apply to the other
424parts of the aggregate.
425
426 6. Conveying Non-Source Forms.
427
428 You may convey a covered work in object code form under the terms
429of sections 4 and 5, provided that you also convey the
430machine-readable Corresponding Source under the terms of this License,
431in one of these ways:
432
433 a) Convey the object code in, or embodied in, a physical product
434 (including a physical distribution medium), accompanied by the
435 Corresponding Source fixed on a durable physical medium
436 customarily used for software interchange.
437
438 b) Convey the object code in, or embodied in, a physical product
439 (including a physical distribution medium), accompanied by a
440 written offer, valid for at least three years and valid for as
441 long as you offer spare parts or customer support for that product
442 model, to give anyone who possesses the object code either (1) a
443 copy of the Corresponding Source for all the software in the
444 product that is covered by this License, on a durable physical
445 medium customarily used for software interchange, for a price no
446 more than your reasonable cost of physically performing this
447 conveying of source, or (2) access to copy the
448 Corresponding Source from a network server at no charge.
449
450 c) Convey individual copies of the object code with a copy of the
451 written offer to provide the Corresponding Source. This
452 alternative is allowed only occasionally and noncommercially, and
453 only if you received the object code with such an offer, in accord
454 with subsection 6b.
455
456 d) Convey the object code by offering access from a designated
457 place (gratis or for a charge), and offer equivalent access to the
458 Corresponding Source in the same way through the same place at no
459 further charge. You need not require recipients to copy the
460 Corresponding Source along with the object code. If the place to
461 copy the object code is a network server, the Corresponding Source
462 may be on a different server (operated by you or a third party)
463 that supports equivalent copying facilities, provided you maintain
464 clear directions next to the object code saying where to find the
465 Corresponding Source. Regardless of what server hosts the
466 Corresponding Source, you remain obligated to ensure that it is
467 available for as long as needed to satisfy these requirements.
468
469 e) Convey the object code using peer-to-peer transmission, provided
470 you inform other peers where the object code and Corresponding
471 Source of the work are being offered to the general public at no
472 charge under subsection 6d.
473
474 A separable portion of the object code, whose source code is excluded
475from the Corresponding Source as a System Library, need not be
476included in conveying the object code work.
477
478 A "User Product" is either (1) a "consumer product", which means any
479tangible personal property which is normally used for personal, family,
480or household purposes, or (2) anything designed or sold for incorporation
481into a dwelling. In determining whether a product is a consumer product,
482doubtful cases shall be resolved in favor of coverage. For a particular
483product received by a particular user, "normally used" refers to a
484typical or common use of that class of product, regardless of the status
485of the particular user or of the way in which the particular user
486actually uses, or expects or is expected to use, the product. A product
487is a consumer product regardless of whether the product has substantial
488commercial, industrial or non-consumer uses, unless such uses represent
489the only significant mode of use of the product.
490
491 "Installation Information" for a User Product means any methods,
492procedures, authorization keys, or other information required to install
493and execute modified versions of a covered work in that User Product from
494a modified version of its Corresponding Source. The information must
495suffice to ensure that the continued functioning of the modified object
496code is in no case prevented or interfered with solely because
497modification has been made.
498
499 If you convey an object code work under this section in, or with, or
500specifically for use in, a User Product, and the conveying occurs as
501part of a transaction in which the right of possession and use of the
502User Product is transferred to the recipient in perpetuity or for a
503fixed term (regardless of how the transaction is characterized), the
504Corresponding Source conveyed under this section must be accompanied
505by the Installation Information. But this requirement does not apply
506if neither you nor any third party retains the ability to install
507modified object code on the User Product (for example, the work has
508been installed in ROM).
509
510 The requirement to provide Installation Information does not include a
511requirement to continue to provide support service, warranty, or updates
512for a work that has been modified or installed by the recipient, or for
513the User Product in which it has been modified or installed. Access to a
514network may be denied when the modification itself materially and
515adversely affects the operation of the network or violates the rules and
516protocols for communication across the network.
517
518 Corresponding Source conveyed, and Installation Information provided,
519in accord with this section must be in a format that is publicly
520documented (and with an implementation available to the public in
521source code form), and must require no special password or key for
522unpacking, reading or copying.
523
524 7. Additional Terms.
525
526 "Additional permissions" are terms that supplement the terms of this
527License by making exceptions from one or more of its conditions.
528Additional permissions that are applicable to the entire Program shall
529be treated as though they were included in this License, to the extent
530that they are valid under applicable law. If additional permissions
531apply only to part of the Program, that part may be used separately
532under those permissions, but the entire Program remains governed by
533this License without regard to the additional permissions.
534
535 When you convey a copy of a covered work, you may at your option
536remove any additional permissions from that copy, or from any part of
537it. (Additional permissions may be written to require their own
538removal in certain cases when you modify the work.) You may place
539additional permissions on material, added by you to a covered work,
540for which you have or can give appropriate copyright permission.
541
542 Notwithstanding any other provision of this License, for material you
543add to a covered work, you may (if authorized by the copyright holders of
544that material) supplement the terms of this License with terms:
545
546 a) Disclaiming warranty or limiting liability differently from the
547 terms of sections 15 and 16 of this License; or
548
549 b) Requiring preservation of specified reasonable legal notices or
550 author attributions in that material or in the Appropriate Legal
551 Notices displayed by works containing it; or
552
553 c) Prohibiting misrepresentation of the origin of that material, or
554 requiring that modified versions of such material be marked in
555 reasonable ways as different from the original version; or
556
557 d) Limiting the use for publicity purposes of names of licensors or
558 authors of the material; or
559
560 e) Declining to grant rights under trademark law for use of some
561 trade names, trademarks, or service marks; or
562
563 f) Requiring indemnification of licensors and authors of that
564 material by anyone who conveys the material (or modified versions of
565 it) with contractual assumptions of liability to the recipient, for
566 any liability that these contractual assumptions directly impose on
567 those licensors and authors.
568
569 All other non-permissive additional terms are considered "further
570restrictions" within the meaning of section 10. If the Program as you
571received it, or any part of it, contains a notice stating that it is
572governed by this License along with a term that is a further
573restriction, you may remove that term. If a license document contains
574a further restriction but permits relicensing or conveying under this
575License, you may add to a covered work material governed by the terms
576of that license document, provided that the further restriction does
577not survive such relicensing or conveying.
578
579 If you add terms to a covered work in accord with this section, you
580must place, in the relevant source files, a statement of the
581additional terms that apply to those files, or a notice indicating
582where to find the applicable terms.
583
584 Additional terms, permissive or non-permissive, may be stated in the
585form of a separately written license, or stated as exceptions;
586the above requirements apply either way.
587
588 8. Termination.
589
590 You may not propagate or modify a covered work except as expressly
591provided under this License. Any attempt otherwise to propagate or
592modify it is void, and will automatically terminate your rights under
593this License (including any patent licenses granted under the third
594paragraph of section 11).
595
596 However, if you cease all violation of this License, then your
597license from a particular copyright holder is reinstated (a)
598provisionally, unless and until the copyright holder explicitly and
599finally terminates your license, and (b) permanently, if the copyright
600holder fails to notify you of the violation by some reasonable means
601prior to 60 days after the cessation.
602
603 Moreover, your license from a particular copyright holder is
604reinstated permanently if the copyright holder notifies you of the
605violation by some reasonable means, this is the first time you have
606received notice of violation of this License (for any work) from that
607copyright holder, and you cure the violation prior to 30 days after
608your receipt of the notice.
609
610 Termination of your rights under this section does not terminate the
611licenses of parties who have received copies or rights from you under
612this License. If your rights have been terminated and not permanently
613reinstated, you do not qualify to receive new licenses for the same
614material under section 10.
615
616 9. Acceptance Not Required for Having Copies.
617
618 You are not required to accept this License in order to receive or
619run a copy of the Program. Ancillary propagation of a covered work
620occurring solely as a consequence of using peer-to-peer transmission
621to receive a copy likewise does not require acceptance. However,
622nothing other than this License grants you permission to propagate or
623modify any covered work. These actions infringe copyright if you do
624not accept this License. Therefore, by modifying or propagating a
625covered work, you indicate your acceptance of this License to do so.
626
627 10. Automatic Licensing of Downstream Recipients.
628
629 Each time you convey a covered work, the recipient automatically
630receives a license from the original licensors, to run, modify and
631propagate that work, subject to this License. You are not responsible
632for enforcing compliance by third parties with this License.
633
634 An "entity transaction" is a transaction transferring control of an
635organization, or substantially all assets of one, or subdividing an
636organization, or merging organizations. If propagation of a covered
637work results from an entity transaction, each party to that
638transaction who receives a copy of the work also receives whatever
639licenses to the work the party's predecessor in interest had or could
640give under the previous paragraph, plus a right to possession of the
641Corresponding Source of the work from the predecessor in interest, if
642the predecessor has it or can get it with reasonable efforts.
643
644 You may not impose any further restrictions on the exercise of the
645rights granted or affirmed under this License. For example, you may
646not impose a license fee, royalty, or other charge for exercise of
647rights granted under this License, and you may not initiate litigation
648(including a cross-claim or counterclaim in a lawsuit) alleging that
649any patent claim is infringed by making, using, selling, offering for
650sale, or importing the Program or any portion of it.
651
652 11. Patents.
653
654 A "contributor" is a copyright holder who authorizes use under this
655License of the Program or a work on which the Program is based. The
656work thus licensed is called the contributor's "contributor version".
657
658 A contributor's "essential patent claims" are all patent claims
659owned or controlled by the contributor, whether already acquired or
660hereafter acquired, that would be infringed by some manner, permitted
661by this License, of making, using, or selling its contributor version,
662but do not include claims that would be infringed only as a
663consequence of further modification of the contributor version. For
664purposes of this definition, "control" includes the right to grant
665patent sublicenses in a manner consistent with the requirements of
666this License.
667
668 Each contributor grants you a non-exclusive, worldwide, royalty-free
669patent license under the contributor's essential patent claims, to
670make, use, sell, offer for sale, import and otherwise run, modify and
671propagate the contents of its contributor version.
672
673 In the following three paragraphs, a "patent license" is any express
674agreement or commitment, however denominated, not to enforce a patent
675(such as an express permission to practice a patent or covenant not to
676sue for patent infringement). To "grant" such a patent license to a
677party means to make such an agreement or commitment not to enforce a
678patent against the party.
679
680 If you convey a covered work, knowingly relying on a patent license,
681and the Corresponding Source of the work is not available for anyone
682to copy, free of charge and under the terms of this License, through a
683publicly available network server or other readily accessible means,
684then you must either (1) cause the Corresponding Source to be so
685available, or (2) arrange to deprive yourself of the benefit of the
686patent license for this particular work, or (3) arrange, in a manner
687consistent with the requirements of this License, to extend the patent
688license to downstream recipients. "Knowingly relying" means you have
689actual knowledge that, but for the patent license, your conveying the
690covered work in a country, or your recipient's use of the covered work
691in a country, would infringe one or more identifiable patents in that
692country that you have reason to believe are valid.
693
694 If, pursuant to or in connection with a single transaction or
695arrangement, you convey, or propagate by procuring conveyance of, a
696covered work, and grant a patent license to some of the parties
697receiving the covered work authorizing them to use, propagate, modify
698or convey a specific copy of the covered work, then the patent license
699you grant is automatically extended to all recipients of the covered
700work and works based on it.
701
702 A patent license is "discriminatory" if it does not include within
703the scope of its coverage, prohibits the exercise of, or is
704conditioned on the non-exercise of one or more of the rights that are
705specifically granted under this License. You may not convey a covered
706work if you are a party to an arrangement with a third party that is
707in the business of distributing software, under which you make payment
708to the third party based on the extent of your activity of conveying
709the work, and under which the third party grants, to any of the
710parties who would receive the covered work from you, a discriminatory
711patent license (a) in connection with copies of the covered work
712conveyed by you (or copies made from those copies), or (b) primarily
713for and in connection with specific products or compilations that
714contain the covered work, unless you entered into that arrangement,
715or that patent license was granted, prior to 28 March 2007.
716
717 Nothing in this License shall be construed as excluding or limiting
718any implied license or other defenses to infringement that may
719otherwise be available to you under applicable patent law.
720
721 12. No Surrender of Others' Freedom.
722
723 If conditions are imposed on you (whether by court order, agreement or
724otherwise) that contradict the conditions of this License, they do not
725excuse you from the conditions of this License. If you cannot convey a
726covered work so as to satisfy simultaneously your obligations under this
727License and any other pertinent obligations, then as a consequence you may
728not convey it at all. For example, if you agree to terms that obligate you
729to collect a royalty for further conveying from those to whom you convey
730the Program, the only way you could satisfy both those terms and this
731License would be to refrain entirely from conveying the Program.
732
733 13. Use with the GNU Affero General Public License.
734
735 Notwithstanding any other provision of this License, you have
736permission to link or combine any covered work with a work licensed
737under version 3 of the GNU Affero General Public License into a single
738combined work, and to convey the resulting work. The terms of this
739License will continue to apply to the part which is the covered work,
740but the special requirements of the GNU Affero General Public License,
741section 13, concerning interaction through a network will apply to the
742combination as such.
743
744 14. Revised Versions of this License.
745
746 The Free Software Foundation may publish revised and/or new versions of
747the GNU General Public License from time to time. Such new versions will
748be similar in spirit to the present version, but may differ in detail to
749address new problems or concerns.
750
751 Each version is given a distinguishing version number. If the
752Program specifies that a certain numbered version of the GNU General
753Public License "or any later version" applies to it, you have the
754option of following the terms and conditions either of that numbered
755version or of any later version published by the Free Software
756Foundation. If the Program does not specify a version number of the
757GNU General Public License, you may choose any version ever published
758by the Free Software Foundation.
759
760 If the Program specifies that a proxy can decide which future
761versions of the GNU General Public License can be used, that proxy's
762public statement of acceptance of a version permanently authorizes you
763to choose that version for the Program.
764
765 Later license versions may give you additional or different
766permissions. However, no additional obligations are imposed on any
767author or copyright holder as a result of your choosing to follow a
768later version.
769
770 15. Disclaimer of Warranty.
771
772 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
773APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
774HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
775OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
776THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
777PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
778IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
779ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
780
781 16. Limitation of Liability.
782
783 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
784WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
785THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
786GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
787USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
788DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
789PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
790EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
791SUCH DAMAGES.
792
793 17. Interpretation of Sections 15 and 16.
794
795 If the disclaimer of warranty and limitation of liability provided
796above cannot be given local legal effect according to their terms,
797reviewing courts shall apply local law that most closely approximates
798an absolute waiver of all civil liability in connection with the
799Program, unless a warranty or assumption of liability accompanies a
800copy of the Program in return for a fee.

9b1afdde 804 How to Apply These Terms to Your New Programs
624ce48e
KL
805
806 If you develop a new program, and you want it to be of the greatest
807possible use to the public, the best way to achieve this is to make it
808free software which everyone can redistribute and change under these terms.
809
810 To do so, attach the following notices to the program. It is safest
811to attach them to the start of each source file to most effectively
812state the exclusion of warranty; and each file should have at least
813the "copyright" line and a pointer to where the full notice is found.
814
815 <one line to give the program's name and a brief idea of what it does.>
816 Copyright (C) <year> <name of author>
817
818 This program is free software: you can redistribute it and/or modify
819 it under the terms of the GNU General Public License as published by
820 the Free Software Foundation, either version 3 of the License, or
821 (at your option) any later version.
822
823 This program is distributed in the hope that it will be useful,
824 but WITHOUT ANY WARRANTY; without even the implied warranty of
825 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
826 GNU General Public License for more details.
827
828 You should have received a copy of the GNU General Public License
829 along with this program. If not, see <http://www.gnu.org/licenses/>.
830
831Also add information on how to contact you by electronic and paper mail.
832
833 If the program does terminal interaction, make it output a short
834notice like this when it starts in an interactive mode:
835
836 <program> Copyright (C) <year> <name of author>
837 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
838 This is free software, and you are welcome to redistribute it
839 under certain conditions; type `show c' for details.
840
841The hypothetical commands `show w' and `show c' should show the appropriate
842parts of the General Public License. Of course, your program's commands
843might be different; for a GUI interface, you would use an "about box".
844
845 You should also get your employer (if you work as a programmer) or school,
846if any, to sign a "copyright disclaimer" for the program, if necessary.
847For more information on this, and how to apply and follow the GNU GPL, see
848<http://www.gnu.org/licenses/>.
849
850 The GNU General Public License does not permit incorporating your program
851into proprietary programs. If your program is a subroutine library, you
852may consider it more useful to permit linking proprietary applications with
853the library. If this is what you want to do, use the GNU Lesser General
854Public License instead of this License. But first, please read
855<http://www.gnu.org/philosophy/why-not-lgpl.html>.
