39=================================
40
41Version 3, 29 June 2007
42
43Copyright &copy; 2007 Free Software Foundation, Inc. &lt;<http://fsf.org/>&gt;
44
45Everyone is permitted to copy and distribute verbatim copies
46of this license document, but changing it is not allowed.
47
48
49This version of the GNU Lesser General Public License incorporates
50the terms and conditions of version 3 of the GNU General Public
51License, supplemented by the additional permissions listed below.
52
53### 0. Additional Definitions.
54
55As used herein, &ldquo;this License&rdquo; refers to version 3 of the GNU Lesser
56General Public License, and the &ldquo;GNU GPL&rdquo; refers to version 3 of the GNU
57General Public License.
58
59&ldquo;The Library&rdquo; refers to a covered work governed by this License,
60other than an Application or a Combined Work as defined below.
61
62An &ldquo;Application&rdquo; is any work that makes use of an interface provided
63by the Library, but which is not otherwise based on the Library.
64Defining a subclass of a class defined by the Library is deemed a mode
65of using an interface provided by the Library.
66
67A &ldquo;Combined Work&rdquo; is a work produced by combining or linking an
68Application with the Library. The particular version of the Library
69with which the Combined Work was made is also called the &ldquo;Linked
70Version&rdquo;.
71
72The &ldquo;Minimal Corresponding Source&rdquo; for a Combined Work means the
73Corresponding Source for the Combined Work, excluding any source code
74for portions of the Combined Work that, considered in isolation, are
75based on the Application, and not on the Linked Version.
76
77The &ldquo;Corresponding Application Code&rdquo; for a Combined Work means the
78object code and/or source code for the Application, including any data
79and utility programs needed for reproducing the Combined Work from the
80Application, but excluding the System Libraries of the Combined Work.
81
82### 1. Exception to Section 3 of the GNU GPL.
83
84You may convey a covered work under sections 3 and 4 of this License
85without being bound by section 3 of the GNU GPL.
86
87### 2. Conveying Modified Versions.
88
89If you modify a copy of the Library, and, in your modifications, a
90facility refers to a function or data to be supplied by an Application
91that uses the facility (other than as an argument passed when the
92facility is invoked), then you may convey a copy of the modified
93version:
94
95* a) under this License, provided that you make a good faith effort to
96ensure that, in the event an Application does not supply the
97function or data, the facility still operates, and performs
98whatever part of its purpose remains meaningful, or
99
100* b) under the GNU GPL, with none of the additional permissions of
101this License applicable to that copy.
102
103### 3. Object Code Incorporating Material from Library Header Files.
104
105The object code form of an Application may incorporate material from
106a header file that is part of the Library. You may convey such object
107code under terms of your choice, provided that, if the incorporated
108material is not limited to numerical parameters, data structure
109layouts and accessors, or small macros, inline functions and templates
110(ten or fewer lines in length), you do both of the following:
111
112* a) Give prominent notice with each copy of the object code that the
113Library is used in it and that the Library and its use are
114covered by this License.
115* b) Accompany the object code with a copy of the GNU GPL and this license
116document.
117
118### 4. Combined Works.
119
120You may convey a Combined Work under terms of your choice that,
121taken together, effectively do not restrict modification of the
122portions of the Library contained in the Combined Work and reverse
123engineering for debugging such modifications, if you also do each of
124the following:
125
126* a) Give prominent notice with each copy of the Combined Work that
127the Library is used in it and that the Library and its use are
128covered by this License.
129
130* b) Accompany the Combined Work with a copy of the GNU GPL and this license
131document.
132
133* c) For a Combined Work that displays copyright notices during
134execution, include the copyright notice for the Library among
135these notices, as well as a reference directing the user to the
136copies of the GNU GPL and this license document.
137
138* d) Do one of the following:
139 - 0) Convey the Minimal Corresponding Source under the terms of this
140License, and the Corresponding Application Code in a form
141suitable for, and under terms that permit, the user to
142recombine or relink the Application with a modified version of
143the Linked Version to produce a modified Combined Work, in the
144manner specified by section 6 of the GNU GPL for conveying
145Corresponding Source.
146 - 1) Use a suitable shared library mechanism for linking with the
147Library. A suitable mechanism is one that (a) uses at run time
148a copy of the Library already present on the user's computer
149system, and (b) will operate properly with a modified version
150of the Library that is interface-compatible with the Linked
151Version.
152
153* e) Provide Installation Information, but only if you would otherwise
154be required to provide such information under section 6 of the
155GNU GPL, and only to the extent that such information is
156necessary to install and execute a modified version of the
157Combined Work produced by recombining or relinking the
158Application with a modified version of the Linked Version. (If
159you use option 4d0, the Installation Information must accompany
160the Minimal Corresponding Source and Corresponding Application
161Code. If you use option 4d1, you must provide the Installation
162Information in the manner specified by section 6 of the GNU GPL
163for conveying Corresponding Source.)
164
165### 5. Combined Libraries.
166
167You may place library facilities that are a work based on the
168Library side by side in a single library together with other library
169facilities that are not Applications and are not covered by this
170License, and convey such a combined library under terms of your
171choice, if you do both of the following:
172
173* a) Accompany the combined library with a copy of the same work based
174on the Library, uncombined with any other library facilities,
175conveyed under the terms of this License.
176* b) Give prominent notice with the combined library that part of it
177is a work based on the Library, and explaining where to find the
178accompanying uncombined form of the same work.
179
180### 6. Revised Versions of the GNU Lesser General Public License.
181
182The Free Software Foundation may publish revised and/or new versions
183of the GNU Lesser General Public License from time to time. Such new
184versions will be similar in spirit to the present version, but may
185differ in detail to address new problems or concerns.
186
187Each version is given a distinguishing version number. If the
188Library as you received it specifies that a certain numbered version
189of the GNU Lesser General Public License &ldquo;or any later version&rdquo;
190applies to it, you have the option of following the terms and
191conditions either of that published version or of any later version
192published by the Free Software Foundation. If the Library as you
193received it does not specify a version number of the GNU Lesser
194General Public License, you may choose any version of the GNU Lesser
195General Public License ever published by the Free Software Foundation.
196
197If the Library as you received it specifies that a proxy can decide
198whether future versions of the GNU Lesser General Public License shall
199apply, that proxy's public statement of acceptance of any version is
200permanent authorization for you to choose that version for the
201Library.
202
203GNU GENERAL PUBLIC LICENSE
204==========================
205
206Version 3, 29 June 2007
207
208> Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
209 Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
210
211# Preamble
212
213 The GNU General Public License is a free, copyleft license for
214software and other kinds of works.
215
216 The licenses for most software and other practical works are designed
217to take away your freedom to share and change the works. By contrast,
218the GNU General Public License is intended to guarantee your freedom to
219share and change all versions of a program--to make sure it remains free
220software for all its users. We, the Free Software Foundation, use the
221GNU General Public License for most of our software; it applies also to
222any other work released this way by its authors. You can apply it to
223your programs, too.
224
225 When we speak of free software, we are referring to freedom, not
226price. Our General Public Licenses are designed to make sure that you
227have the freedom to distribute copies of free software (and charge for
228them if you wish), that you receive source code or can get it if you
229want it, that you can change the software or use pieces of it in new
230free programs, and that you know you can do these things.
231
232 To protect your rights, we need to prevent others from denying you
233these rights or asking you to surrender the rights. Therefore, you have
234certain responsibilities if you distribute copies of the software, or if
235you modify it: responsibilities to respect the freedom of others.
236
237 For example, if you distribute copies of such a program, whether
238gratis or for a fee, you must pass on to the recipients the same
239freedoms that you received. You must make sure that they, too, receive
240or can get the source code. And you must show them these terms so they
241know their rights.
242
243 Developers that use the GNU GPL protect your rights with two steps:
244(1) assert copyright on the software, and (2) offer you this License
245giving you legal permission to copy, distribute and/or modify it.
246
247 For the developers' and authors' protection, the GPL clearly explains
248that there is no warranty for this free software. For both users' and
249authors' sake, the GPL requires that modified versions be marked as
250changed, so that their problems will not be attributed erroneously to
251authors of previous versions.
252
253 Some devices are designed to deny users access to install or run
254modified versions of the software inside them, although the manufacturer
255can do so. This is fundamentally incompatible with the aim of
256protecting users' freedom to change the software. The systematic
257pattern of such abuse occurs in the area of products for individuals to
258use, which is precisely where it is most unacceptable. Therefore, we
259have designed this version of the GPL to prohibit the practice for those
260products. If such problems arise substantially in other domains, we
261stand ready to extend this provision to those domains in future versions
262of the GPL, as needed to protect the freedom of users.
263
264 Finally, every program is threatened constantly by software patents.
265States should not allow patents to restrict development and use of
266software on general-purpose computers, but in those that do, we wish to
267avoid the special danger that patents applied to a free program could
268make it effectively proprietary. To prevent this, the GPL assures that
269patents cannot be used to render the program non-free.
270
271 The precise terms and conditions for copying, distribution and
272modification follow.
273
274# TERMS AND CONDITIONS
275
276## 0. Definitions.
277
278 _"This License"_ refers to version 3 of the GNU General Public License.
279
280 _"Copyright"_ also means copyright-like laws that apply to other kinds of
281works, such as semiconductor masks.
282
283 _"The Program"_ refers to any copyrightable work licensed under this
284License. Each licensee is addressed as _"you"_. _"Licensees"_ and
285"recipients" may be individuals or organizations.
286
287 To _"modify"_ a work means to copy from or adapt all or part of the work
288in a fashion requiring copyright permission, other than the making of an
289exact copy. The resulting work is called a _"modified version"_ of the
290earlier work or a work _"based on"_ the earlier work.
291
292 A _"covered work"_ means either the unmodified Program or a work based
293on the Program.
294
295 To _"propagate"_ a work means to do anything with it that, without
296permission, would make you directly or secondarily liable for
297infringement under applicable copyright law, except executing it on a
298computer or modifying a private copy. Propagation includes copying,
299distribution (with or without modification), making available to the
300public, and in some countries other activities as well.
301
302 To _"convey"_ a work means any kind of propagation that enables other
303parties to make or receive copies. Mere interaction with a user through
304a computer network, with no transfer of a copy, is not conveying.
305
306 An interactive user interface displays "Appropriate Legal Notices"
307to the extent that it includes a convenient and prominently visible
308feature that (1) displays an appropriate copyright notice, and (2)
309tells the user that there is no warranty for the work (except to the
310extent that warranties are provided), that licensees may convey the
311work under this License, and how to view a copy of this License. If
312the interface presents a list of user commands or options, such as a
313menu, a prominent item in the list meets this criterion.
314
315## 1. Source Code.
316
317 The _"source code"_ for a work means the preferred form of the work
318for making modifications to it. _"Object code"_ means any non-source
319form of a work.
320
321 A _"Standard Interface"_ means an interface that either is an official
322standard defined by a recognized standards body, or, in the case of
323interfaces specified for a particular programming language, one that
324is widely used among developers working in that language.
325
326 The _"System Libraries"_ of an executable work include anything, other
327than the work as a whole, that (a) is included in the normal form of
328packaging a Major Component, but which is not part of that Major
329Component, and (b) serves only to enable use of the work with that
330Major Component, or to implement a Standard Interface for which an
331implementation is available to the public in source code form. A
332"Major Component", in this context, means a major essential component
333(kernel, window system, and so on) of the specific operating system
334(if any) on which the executable work runs, or a compiler used to
335produce the work, or an object code interpreter used to run it.
336
337 The _"Corresponding Source"_ for a work in object code form means all
338the source code needed to generate, install, and (for an executable
339work) run the object code and to modify the work, including scripts to
340control those activities. However, it does not include the work's
341System Libraries, or general-purpose tools or generally available free
342programs which are used unmodified in performing those activities but
343which are not part of the work. For example, Corresponding Source
344includes interface definition files associated with source files for
345the work, and the source code for shared libraries and dynamically
346linked subprograms that the work is specifically designed to require,
347such as by intimate data communication or control flow between those
348subprograms and other parts of the work.
349
350 The Corresponding Source need not include anything that users
351can regenerate automatically from other parts of the Corresponding
352Source.
353
354 The Corresponding Source for a work in source code form is that
355same work.
356
357## 2. Basic Permissions.
358
359 All rights granted under this License are granted for the term of
360copyright on the Program, and are irrevocable provided the stated
361conditions are met. This License explicitly affirms your unlimited
362permission to run the unmodified Program. The output from running a
363covered work is covered by this License only if the output, given its
364content, constitutes a covered work. This License acknowledges your
365rights of fair use or other equivalent, as provided by copyright law.
366
367 You may make, run and propagate covered works that you do not
368convey, without conditions so long as your license otherwise remains
369in force. You may convey covered works to others for the sole purpose
370of having them make modifications exclusively for you, or provide you
371with facilities for running those works, provided that you comply with
372the terms of this License in conveying all material for which you do
373not control copyright. Those thus making or running the covered works
374for you must do so exclusively on your behalf, under your direction
375and control, on terms that prohibit them from making any copies of
376your copyrighted material outside their relationship with you.
377
378 Conveying under any other circumstances is permitted solely under
379the conditions stated below. Sublicensing is not allowed; section 10
380makes it unnecessary.
381
382## 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
383
384 No covered work shall be deemed part of an effective technological
385measure under any applicable law fulfilling obligations under article
38611 of the WIPO copyright treaty adopted on 20 December 1996, or
387similar laws prohibiting or restricting circumvention of such
388measures.
389
390 When you convey a covered work, you waive any legal power to forbid
391circumvention of technological measures to the extent such circumvention
392is effected by exercising rights under this License with respect to
393the covered work, and you disclaim any intention to limit operation or
394modification of the work as a means of enforcing, against the work's
395users, your or third parties' legal rights to forbid circumvention of
396technological measures.
397
398## 4. Conveying Verbatim Copies.
399
400 You may convey verbatim copies of the Program's source code as you
401receive it, in any medium, provided that you conspicuously and
402appropriately publish on each copy an appropriate copyright notice;
403keep intact all notices stating that this License and any
404non-permissive terms added in accord with section 7 apply to the code;
405keep intact all notices of the absence of any warranty; and give all
406recipients a copy of this License along with the Program.
407
408 You may charge any price or no price for each copy that you convey,
409and you may offer support or warranty protection for a fee.
410
411## 5. Conveying Modified Source Versions.
412
413 You may convey a work based on the Program, or the modifications to
414produce it from the Program, in the form of source code under the
415terms of section 4, provided that you also meet all of these conditions:
416
417 a) The work must carry prominent notices stating that you modified
418 it, and giving a relevant date.
419
420 b) The work must carry prominent notices stating that it is
421 released under this License and any conditions added under section
422 7. This requirement modifies the requirement in section 4 to
423 "keep intact all notices".
424
425 c) You must license the entire work, as a whole, under this
426 License to anyone who comes into possession of a copy. This
427 License will therefore apply, along with any applicable section 7
428 additional terms, to the whole of the work, and all its parts,
429 regardless of how they are packaged. This License gives no
430 permission to license the work in any other way, but it does not
431 invalidate such permission if you have separately received it.
432
433 d) If the work has interactive user interfaces, each must display
434 Appropriate Legal Notices; however, if the Program has interactive
435 interfaces that do not display Appropriate Legal Notices, your
436 work need not make them do so.
437
438 A compilation of a covered work with other separate and independent
439works, which are not by their nature extensions of the covered work,
440and which are not combined with it such as to form a larger program,
441in or on a volume of a storage or distribution medium, is called an
442"aggregate" if the compilation and its resulting copyright are not
443used to limit the access or legal rights of the compilation's users
444beyond what the individual works permit. Inclusion of a covered work
445in an aggregate does not cause this License to apply to the other
446parts of the aggregate.
447
448## 6. Conveying Non-Source Forms.
449
450 You may convey a covered work in object code form under the terms
451of sections 4 and 5, provided that you also convey the
452machine-readable Corresponding Source under the terms of this License,
453in one of these ways:
454
455 a) Convey the object code in, or embodied in, a physical product
456 (including a physical distribution medium), accompanied by the
457 Corresponding Source fixed on a durable physical medium
458 customarily used for software interchange.
459
460 b) Convey the object code in, or embodied in, a physical product
461 (including a physical distribution medium), accompanied by a
462 written offer, valid for at least three years and valid for as
463 long as you offer spare parts or customer support for that product
464 model, to give anyone who possesses the object code either (1) a
465 copy of the Corresponding Source for all the software in the
466 product that is covered by this License, on a durable physical
467 medium customarily used for software interchange, for a price no
468 more than your reasonable cost of physically performing this
469 conveying of source, or (2) access to copy the
470 Corresponding Source from a network server at no charge.
471
472 c) Convey individual copies of the object code with a copy of the
473 written offer to provide the Corresponding Source. This
474 alternative is allowed only occasionally and noncommercially, and
475 only if you received the object code with such an offer, in accord
476 with subsection 6b.
477
478 d) Convey the object code by offering access from a designated
479 place (gratis or for a charge), and offer equivalent access to the
480 Corresponding Source in the same way through the same place at no
481 further charge. You need not require recipients to copy the
482 Corresponding Source along with the object code. If the place to
483 copy the object code is a network server, the Corresponding Source
484 may be on a different server (operated by you or a third party)
485 that supports equivalent copying facilities, provided you maintain
486 clear directions next to the object code saying where to find the
487 Corresponding Source. Regardless of what server hosts the
488 Corresponding Source, you remain obligated to ensure that it is
489 available for as long as needed to satisfy these requirements.
490
491 e) Convey the object code using peer-to-peer transmission, provided
492 you inform other peers where the object code and Corresponding
493 Source of the work are being offered to the general public at no
494 charge under subsection 6d.
495
496 A separable portion of the object code, whose source code is excluded
497from the Corresponding Source as a System Library, need not be
498included in conveying the object code work.
499
500 A _"User Product"_ is either (1) a _"consumer product"_, which means any
501tangible personal property which is normally used for personal, family,
502or household purposes, or (2) anything designed or sold for incorporation
503into a dwelling. In determining whether a product is a consumer product,
504doubtful cases shall be resolved in favor of coverage. For a particular
505product received by a particular user, "normally used" refers to a
506typical or common use of that class of product, regardless of the status
507of the particular user or of the way in which the particular user
508actually uses, or expects or is expected to use, the product. A product
509is a consumer product regardless of whether the product has substantial
510commercial, industrial or non-consumer uses, unless such uses represent
511the only significant mode of use of the product.
512
513 _"Installation Information"_ for a User Product means any methods,
514procedures, authorization keys, or other information required to install
515and execute modified versions of a covered work in that User Product from
516a modified version of its Corresponding Source. The information must
517suffice to ensure that the continued functioning of the modified object
518code is in no case prevented or interfered with solely because
519modification has been made.
520
521 If you convey an object code work under this section in, or with, or
522specifically for use in, a User Product, and the conveying occurs as
523part of a transaction in which the right of possession and use of the
524User Product is transferred to the recipient in perpetuity or for a
525fixed term (regardless of how the transaction is characterized), the
526Corresponding Source conveyed under this section must be accompanied
527by the Installation Information. But this requirement does not apply
528if neither you nor any third party retains the ability to install
529modified object code on the User Product (for example, the work has
530been installed in ROM).
531
532 The requirement to provide Installation Information does not include a
533requirement to continue to provide support service, warranty, or updates
534for a work that has been modified or installed by the recipient, or for
535the User Product in which it has been modified or installed. Access to a
536network may be denied when the modification itself materially and
537adversely affects the operation of the network or violates the rules and
538protocols for communication across the network.
539
540 Corresponding Source conveyed, and Installation Information provided,
541in accord with this section must be in a format that is publicly
542documented (and with an implementation available to the public in
543source code form), and must require no special password or key for
544unpacking, reading or copying.
545
546## 7. Additional Terms.
547
548 _"Additional permissions"_ are terms that supplement the terms of this
549License by making exceptions from one or more of its conditions.
550Additional permissions that are applicable to the entire Program shall
551be treated as though they were included in this License, to the extent
552that they are valid under applicable law. If additional permissions
553apply only to part of the Program, that part may be used separately
554under those permissions, but the entire Program remains governed by
555this License without regard to the additional permissions.
556
557 When you convey a copy of a covered work, you may at your option
558remove any additional permissions from that copy, or from any part of
559it. (Additional permissions may be written to require their own
560removal in certain cases when you modify the work.) You may place
561additional permissions on material, added by you to a covered work,
562for which you have or can give appropriate copyright permission.
563
564 Notwithstanding any other provision of this License, for material you
565add to a covered work, you may (if authorized by the copyright holders of
566that material) supplement the terms of this License with terms:
567
568 a) Disclaiming warranty or limiting liability differently from the
569 terms of sections 15 and 16 of this License; or
570
571 b) Requiring preservation of specified reasonable legal notices or
572 author attributions in that material or in the Appropriate Legal
573 Notices displayed by works containing it; or
574
575 c) Prohibiting misrepresentation of the origin of that material, or
576 requiring that modified versions of such material be marked in
577 reasonable ways as different from the original version; or
578
579 d) Limiting the use for publicity purposes of names of licensors or
580 authors of the material; or
581
582 e) Declining to grant rights under trademark law for use of some
583 trade names, trademarks, or service marks; or
584
585 f) Requiring indemnification of licensors and authors of that
586 material by anyone who conveys the material (or modified versions of
587 it) with contractual assumptions of liability to the recipient, for
588 any liability that these contractual assumptions directly impose on
589 those licensors and authors.
590
591 All other non-permissive additional terms are considered "further
592restrictions" within the meaning of section 10. If the Program as you
593received it, or any part of it, contains a notice stating that it is
594governed by this License along with a term that is a further
595restriction, you may remove that term. If a license document contains
596a further restriction but permits relicensing or conveying under this
597License, you may add to a covered work material governed by the terms
598of that license document, provided that the further restriction does
599not survive such relicensing or conveying.
600
601 If you add terms to a covered work in accord with this section, you
602must place, in the relevant source files, a statement of the
603additional terms that apply to those files, or a notice indicating
604where to find the applicable terms.
605
606 Additional terms, permissive or non-permissive, may be stated in the
607form of a separately written license, or stated as exceptions;
608the above requirements apply either way.
609
610## 8. Termination.
611
612 You may not propagate or modify a covered work except as expressly
613provided under this License. Any attempt otherwise to propagate or
614modify it is void, and will automatically terminate your rights under
615this License (including any patent licenses granted under the third
616paragraph of section 11).
617
618 However, if you cease all violation of this License, then your
619license from a particular copyright holder is reinstated (a)
620provisionally, unless and until the copyright holder explicitly and
621finally terminates your license, and (b) permanently, if the copyright
622holder fails to notify you of the violation by some reasonable means
623prior to 60 days after the cessation.
624
625 Moreover, your license from a particular copyright holder is
626reinstated permanently if the copyright holder notifies you of the
627violation by some reasonable means, this is the first time you have
628received notice of violation of this License (for any work) from that
629copyright holder, and you cure the violation prior to 30 days after
630your receipt of the notice.
631
632 Termination of your rights under this section does not terminate the
633licenses of parties who have received copies or rights from you under
634this License. If your rights have been terminated and not permanently
635reinstated, you do not qualify to receive new licenses for the same
636material under section 10.
637
638## 9. Acceptance Not Required for Having Copies.
639
640 You are not required to accept this License in order to receive or
641run a copy of the Program. Ancillary propagation of a covered work
642occurring solely as a consequence of using peer-to-peer transmission
643to receive a copy likewise does not require acceptance. However,
644nothing other than this License grants you permission to propagate or
645modify any covered work. These actions infringe copyright if you do
646not accept this License. Therefore, by modifying or propagating a
647covered work, you indicate your acceptance of this License to do so.
648
649## 10. Automatic Licensing of Downstream Recipients.
650
651 Each time you convey a covered work, the recipient automatically
652receives a license from the original licensors, to run, modify and
653propagate that work, subject to this License. You are not responsible
654for enforcing compliance by third parties with this License.
655
656 An _"entity transaction"_ is a transaction transferring control of an
657organization, or substantially all assets of one, or subdividing an
658organization, or merging organizations. If propagation of a covered
659work results from an entity transaction, each party to that
660transaction who receives a copy of the work also receives whatever
661licenses to the work the party's predecessor in interest had or could
662give under the previous paragraph, plus a right to possession of the
663Corresponding Source of the work from the predecessor in interest, if
664the predecessor has it or can get it with reasonable efforts.
665
666 You may not impose any further restrictions on the exercise of the
667rights granted or affirmed under this License. For example, you may
668not impose a license fee, royalty, or other charge for exercise of
669rights granted under this License, and you may not initiate litigation
670(including a cross-claim or counterclaim in a lawsuit) alleging that
671any patent claim is infringed by making, using, selling, offering for
672sale, or importing the Program or any portion of it.
673
674## 11. Patents.
675
676 A _"contributor"_ is a copyright holder who authorizes use under this
677License of the Program or a work on which the Program is based. The
678work thus licensed is called the contributor's "contributor version".
679
680 A contributor's _"essential patent claims"_ are all patent claims
681owned or controlled by the contributor, whether already acquired or
682hereafter acquired, that would be infringed by some manner, permitted
683by this License, of making, using, or selling its contributor version,
684but do not include claims that would be infringed only as a
685consequence of further modification of the contributor version. For
686purposes of this definition, "control" includes the right to grant
687patent sublicenses in a manner consistent with the requirements of
688this License.
689
690 Each contributor grants you a non-exclusive, worldwide, royalty-free
691patent license under the contributor's essential patent claims, to
692make, use, sell, offer for sale, import and otherwise run, modify and
693propagate the contents of its contributor version.
694
695 In the following three paragraphs, a "patent license" is any express
696agreement or commitment, however denominated, not to enforce a patent
697(such as an express permission to practice a patent or covenant not to
698sue for patent infringement). To "grant" such a patent license to a
699party means to make such an agreement or commitment not to enforce a
700patent against the party.
701
702 If you convey a covered work, knowingly relying on a patent license,
703and the Corresponding Source of the work is not available for anyone
704to copy, free of charge and under the terms of this License, through a
705publicly available network server or other readily accessible means,
706then you must either (1) cause the Corresponding Source to be so
707available, or (2) arrange to deprive yourself of the benefit of the
708patent license for this particular work, or (3) arrange, in a manner
709consistent with the requirements of this License, to extend the patent
710license to downstream recipients. "Knowingly relying" means you have
711actual knowledge that, but for the patent license, your conveying the
712covered work in a country, or your recipient's use of the covered work
713in a country, would infringe one or more identifiable patents in that
714country that you have reason to believe are valid.
715
716 If, pursuant to or in connection with a single transaction or
717arrangement, you convey, or propagate by procuring conveyance of, a
718covered work, and grant a patent license to some of the parties
719receiving the covered work authorizing them to use, propagate, modify
720or convey a specific copy of the covered work, then the patent license
721you grant is automatically extended to all recipients of the covered
722work and works based on it.
723
724 A patent license is "discriminatory" if it does not include within
725the scope of its coverage, prohibits the exercise of, or is
726conditioned on the non-exercise of one or more of the rights that are
727specifically granted under this License. You may not convey a covered
728work if you are a party to an arrangement with a third party that is
729in the business of distributing software, under which you make payment
730to the third party based on the extent of your activity of conveying
731the work, and under which the third party grants, to any of the
732parties who would receive the covered work from you, a discriminatory
733patent license (a) in connection with copies of the covered work
734conveyed by you (or copies made from those copies), or (b) primarily
735for and in connection with specific products or compilations that
736contain the covered work, unless you entered into that arrangement,
737or that patent license was granted, prior to 28 March 2007.
738
739 Nothing in this License shall be construed as excluding or limiting
740any implied license or other defenses to infringement that may
741otherwise be available to you under applicable patent law.
742
743## 12. No Surrender of Others' Freedom.
744
745 If conditions are imposed on you (whether by court order, agreement or
746otherwise) that contradict the conditions of this License, they do not
747excuse you from the conditions of this License. If you cannot convey a
748covered work so as to satisfy simultaneously your obligations under this
749License and any other pertinent obligations, then as a consequence you may
750not convey it at all. For example, if you agree to terms that obligate you
751to collect a royalty for further conveying from those to whom you convey
752the Program, the only way you could satisfy both those terms and this
753License would be to refrain entirely from conveying the Program.
754
755## 13. Use with the GNU Affero General Public License.
756
757 Notwithstanding any other provision of this License, you have
758permission to link or combine any covered work with a work licensed
759under version 3 of the GNU Affero General Public License into a single
760combined work, and to convey the resulting work. The terms of this
761License will continue to apply to the part which is the covered work,
762but the special requirements of the GNU Affero General Public License,
763section 13, concerning interaction through a network will apply to the
764combination as such.
765
766## 14. Revised Versions of this License.
767
768 The Free Software Foundation may publish revised and/or new versions of
769the GNU General Public License from time to time. Such new versions will
770be similar in spirit to the present version, but may differ in detail to
771address new problems or concerns.
772
773 Each version is given a distinguishing version number. If the
774Program specifies that a certain numbered version of the GNU General
775Public License "or any later version" applies to it, you have the
776option of following the terms and conditions either of that numbered
777version or of any later version published by the Free Software
778Foundation. If the Program does not specify a version number of the
779GNU General Public License, you may choose any version ever published
780by the Free Software Foundation.
781
782 If the Program specifies that a proxy can decide which future
783versions of the GNU General Public License can be used, that proxy's
784public statement of acceptance of a version permanently authorizes you
785to choose that version for the Program.
786
787 Later license versions may give you additional or different
788permissions. However, no additional obligations are imposed on any
789author or copyright holder as a result of your choosing to follow a
790later version.
791
792## 15. Disclaimer of Warranty.
793
794 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
795APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
796HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
797OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
798THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
799PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
800IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
801ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
802
803## 16. Limitation of Liability.
804
805 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
806WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
807THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
808GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
809USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
810DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
811PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
812EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
813SUCH DAMAGES.
814
815## 17. Interpretation of Sections 15 and 16.
816
817 If the disclaimer of warranty and limitation of liability provided
818above cannot be given local legal effect according to their terms,
819reviewing courts shall apply local law that most closely approximates
820an absolute waiver of all civil liability in connection with the
821Program, unless a warranty or assumption of liability accompanies a
822copy of the Program in return for a fee.
823

827
828# How to Apply These Terms to Your New Programs
829
830 If you develop a new program, and you want it to be of the greatest
831possible use to the public, the best way to achieve this is to make it
832free software which everyone can redistribute and change under these terms.
833
834 To do so, attach the following notices to the program. It is safest
835to attach them to the start of each source file to most effectively
836state the exclusion of warranty; and each file should have at least
837the "copyright" line and a pointer to where the full notice is found.
838
839 <one line to give the program's name and a brief idea of what it does.>
840 Copyright (C) <year> <name of author>
841
842 This program is free software: you can redistribute it and/or modify
843 it under the terms of the GNU General Public License as published by
844 the Free Software Foundation, either version 3 of the License, or
845 (at your option) any later version.
846
847 This program is distributed in the hope that it will be useful,
848 but WITHOUT ANY WARRANTY; without even the implied warranty of
849 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
850 GNU General Public License for more details.
851
852 You should have received a copy of the GNU General Public License
853 along with this program. If not, see <http://www.gnu.org/licenses/>.
854
855Also add information on how to contact you by electronic and paper mail.
856
857 If the program does terminal interaction, make it output a short
858notice like this when it starts in an interactive mode:
859
860 <program> Copyright (C) <year> <name of author>
861 This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.
862 This is free software, and you are welcome to redistribute it
863 under certain conditions; type 'show c' for details.
864
865 The hypothetical commands _'show w'_ and _'show c'_ should show the appropriate
866parts of the General Public License. Of course, your program's commands
867might be different; for a GUI interface, you would use an "about box".
868
869 You should also get your employer (if you work as a programmer) or school,
870if any, to sign a "copyright disclaimer" for the program, if necessary.
871For more information on this, and how to apply and follow the GNU GPL, see
872<http://www.gnu.org/licenses/>.
873
874 The GNU General Public License does not permit incorporating your program
875into proprietary programs. If your program is a subroutine library, you
876may consider it more useful to permit linking proprietary applications with
877the library. If this is what you want to do, use the GNU Lesser General
878Public License instead of this License. But first, please read
879<http://www.gnu.org/philosophy/why-not-lgpl.html>.
