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
21 the terms and conditions of version 3 of the GNU General Public
22 License, 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
27 General Public License, and the "GNU GPL" refers to version 3 of the GNU
28 General Public License.
29
30 "The Library" refers to a covered work governed by this License,
31 other than an Application or a Combined Work as defined below.
32
33 An "Application" is any work that makes use of an interface provided
34 by the Library, but which is not otherwise based on the Library.
35 Defining a subclass of a class defined by the Library is deemed a mode
36 of using an interface provided by the Library.
37
38 A "Combined Work" is a work produced by combining or linking an
39 Application with the Library. The particular version of the Library
40 with which the Combined Work was made is also called the "Linked
41 Version".
42
43 The "Minimal Corresponding Source" for a Combined Work means the
44 Corresponding Source for the Combined Work, excluding any source code
45 for portions of the Combined Work that, considered in isolation, are
46 based on the Application, and not on the Linked Version.
47
48 The "Corresponding Application Code" for a Combined Work means the
49 object code and/or source code for the Application, including any data
50 and utility programs needed for reproducing the Combined Work from the
51 Application, 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
56 without 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
61 facility refers to a function or data to be supplied by an Application
62 that uses the facility (other than as an argument passed when the
63 facility is invoked), then you may convey a copy of the modified
64 version:
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
77 a header file that is part of the Library. You may convey such object
78 code under terms of your choice, provided that, if the incorporated
79 material is not limited to numerical parameters, data structure
80 layouts 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,
93 taken together, effectively do not restrict modification of the
94 portions of the Library contained in the Combined Work and reverse
95 engineering for debugging such modifications, if you also do each of
96 the 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
142 Library side by side in a single library together with other library
143 facilities that are not Applications and are not covered by this
144 License, and convey such a combined library under terms of your
145 choice, 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
158 of the GNU Lesser General Public License from time to time. Such new
159 versions will be similar in spirit to the present version, but may
160 differ in detail to address new problems or concerns.
161
162 Each version is given a distinguishing version number. If the
163 Library as you received it specifies that a certain numbered version
164 of the GNU Lesser General Public License "or any later version"
165 applies to it, you have the option of following the terms and
166 conditions either of that published version or of any later version
167 published by the Free Software Foundation. If the Library as you
168 received it does not specify a version number of the GNU Lesser
169 General Public License, you may choose any version of the GNU Lesser
170 General Public License ever published by the Free Software Foundation.
171
172 If the Library as you received it specifies that a proxy can decide
173 whether future versions of the GNU Lesser General Public License shall
174 apply, that proxy's public statement of acceptance of any version is
175 permanent authorization for you to choose that version for the
176 Library.

182 GNU GENERAL PUBLIC LICENSE
183 Version 3, 29 June 2007
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
189 Preamble
190
191 The GNU General Public License is a free, copyleft license for
192 software and other kinds of works.
193
194 The licenses for most software and other practical works are designed
195 to take away your freedom to share and change the works. By contrast,
196 the GNU General Public License is intended to guarantee your freedom to
197 share and change all versions of a program--to make sure it remains free
198 software for all its users. We, the Free Software Foundation, use the
199 GNU General Public License for most of our software; it applies also to
200 any other work released this way by its authors. You can apply it to
201 your programs, too.
202
203 When we speak of free software, we are referring to freedom, not
204 price. Our General Public Licenses are designed to make sure that you
205 have the freedom to distribute copies of free software (and charge for
206 them if you wish), that you receive source code or can get it if you
207 want it, that you can change the software or use pieces of it in new
208 free programs, and that you know you can do these things.
209
210 To protect your rights, we need to prevent others from denying you
211 these rights or asking you to surrender the rights. Therefore, you have
212 certain responsibilities if you distribute copies of the software, or if
213 you modify it: responsibilities to respect the freedom of others.
214
215 For example, if you distribute copies of such a program, whether
216 gratis or for a fee, you must pass on to the recipients the same
217 freedoms that you received. You must make sure that they, too, receive
218 or can get the source code. And you must show them these terms so they
219 know 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
223 giving you legal permission to copy, distribute and/or modify it.
224
225 For the developers' and authors' protection, the GPL clearly explains
226 that there is no warranty for this free software. For both users' and
227 authors' sake, the GPL requires that modified versions be marked as
228 changed, so that their problems will not be attributed erroneously to
229 authors of previous versions.
230
231 Some devices are designed to deny users access to install or run
232 modified versions of the software inside them, although the manufacturer
233 can do so. This is fundamentally incompatible with the aim of
234 protecting users' freedom to change the software. The systematic
235 pattern of such abuse occurs in the area of products for individuals to
236 use, which is precisely where it is most unacceptable. Therefore, we
237 have designed this version of the GPL to prohibit the practice for those
238 products. If such problems arise substantially in other domains, we
239 stand ready to extend this provision to those domains in future versions
240 of the GPL, as needed to protect the freedom of users.
241
242 Finally, every program is threatened constantly by software patents.
243 States should not allow patents to restrict development and use of
244 software on general-purpose computers, but in those that do, we wish to
245 avoid the special danger that patents applied to a free program could
246 make it effectively proprietary. To prevent this, the GPL assures that
247 patents cannot be used to render the program non-free.
248
249 The precise terms and conditions for copying, distribution and
250 modification follow.
251
252 TERMS AND CONDITIONS
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
259 works, such as semiconductor masks.
260
261 "The Program" refers to any copyrightable work licensed under this
262 License. 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
266 in a fashion requiring copyright permission, other than the making of an
267 exact copy. The resulting work is called a "modified version" of the
268 earlier work or a work "based on" the earlier work.
269
270 A "covered work" means either the unmodified Program or a work based
271 on the Program.
272
273 To "propagate" a work means to do anything with it that, without
274 permission, would make you directly or secondarily liable for
275 infringement under applicable copyright law, except executing it on a
276 computer or modifying a private copy. Propagation includes copying,
277 distribution (with or without modification), making available to the
278 public, and in some countries other activities as well.
279
280 To "convey" a work means any kind of propagation that enables other
281 parties to make or receive copies. Mere interaction with a user through
282 a computer network, with no transfer of a copy, is not conveying.
283
284 An interactive user interface displays "Appropriate Legal Notices"
285 to the extent that it includes a convenient and prominently visible
286 feature that (1) displays an appropriate copyright notice, and (2)
287 tells the user that there is no warranty for the work (except to the
288 extent that warranties are provided), that licensees may convey the
289 work under this License, and how to view a copy of this License. If
290 the interface presents a list of user commands or options, such as a
291 menu, 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
296 for making modifications to it. "Object code" means any non-source
297 form of a work.
298
299 A "Standard Interface" means an interface that either is an official
300 standard defined by a recognized standards body, or, in the case of
301 interfaces specified for a particular programming language, one that
302 is widely used among developers working in that language.
303
304 The "System Libraries" of an executable work include anything, other
305 than the work as a whole, that (a) is included in the normal form of
306 packaging a Major Component, but which is not part of that Major
307 Component, and (b) serves only to enable use of the work with that
308 Major Component, or to implement a Standard Interface for which an
309 implementation 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
313 produce 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
316 the source code needed to generate, install, and (for an executable
317 work) run the object code and to modify the work, including scripts to
318 control those activities. However, it does not include the work's
319 System Libraries, or general-purpose tools or generally available free
320 programs which are used unmodified in performing those activities but
321 which are not part of the work. For example, Corresponding Source
322 includes interface definition files associated with source files for
323 the work, and the source code for shared libraries and dynamically
324 linked subprograms that the work is specifically designed to require,
325 such as by intimate data communication or control flow between those
326 subprograms and other parts of the work.
327
328 The Corresponding Source need not include anything that users
329 can regenerate automatically from other parts of the Corresponding
330 Source.
331
332 The Corresponding Source for a work in source code form is that
333 same work.
334
335 2. Basic Permissions.
336
337 All rights granted under this License are granted for the term of
338 copyright on the Program, and are irrevocable provided the stated
339 conditions are met. This License explicitly affirms your unlimited
340 permission to run the unmodified Program. The output from running a
341 covered work is covered by this License only if the output, given its
342 content, constitutes a covered work. This License acknowledges your
343 rights 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
346 convey, without conditions so long as your license otherwise remains
347 in force. You may convey covered works to others for the sole purpose
348 of having them make modifications exclusively for you, or provide you
349 with facilities for running those works, provided that you comply with
350 the terms of this License in conveying all material for which you do
351 not control copyright. Those thus making or running the covered works
352 for you must do so exclusively on your behalf, under your direction
353 and control, on terms that prohibit them from making any copies of
354 your copyrighted material outside their relationship with you.
355
356 Conveying under any other circumstances is permitted solely under
357 the conditions stated below. Sublicensing is not allowed; section 10
358 makes 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
363 measure under any applicable law fulfilling obligations under article
364 11 of the WIPO copyright treaty adopted on 20 December 1996, or
365 similar laws prohibiting or restricting circumvention of such
366 measures.
367
368 When you convey a covered work, you waive any legal power to forbid
369 circumvention of technological measures to the extent such circumvention
370 is effected by exercising rights under this License with respect to
371 the covered work, and you disclaim any intention to limit operation or
372 modification of the work as a means of enforcing, against the work's
373 users, your or third parties' legal rights to forbid circumvention of
374 technological measures.
375
376 4. Conveying Verbatim Copies.
377
378 You may convey verbatim copies of the Program's source code as you
379 receive it, in any medium, provided that you conspicuously and
380 appropriately publish on each copy an appropriate copyright notice;
381 keep intact all notices stating that this License and any
382 non-permissive terms added in accord with section 7 apply to the code;
383 keep intact all notices of the absence of any warranty; and give all
384 recipients 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,
387 and 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
392 produce it from the Program, in the form of source code under the
393 terms 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
417 works, which are not by their nature extensions of the covered work,
418 and which are not combined with it such as to form a larger program,
419 in or on a volume of a storage or distribution medium, is called an
420 "aggregate" if the compilation and its resulting copyright are not
421 used to limit the access or legal rights of the compilation's users
422 beyond what the individual works permit. Inclusion of a covered work
423 in an aggregate does not cause this License to apply to the other
424 parts 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
429 of sections 4 and 5, provided that you also convey the
430 machine-readable Corresponding Source under the terms of this License,
431 in 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
475 from the Corresponding Source as a System Library, need not be
476 included in conveying the object code work.
477
478 A "User Product" is either (1) a "consumer product", which means any
479 tangible personal property which is normally used for personal, family,
480 or household purposes, or (2) anything designed or sold for incorporation
481 into a dwelling. In determining whether a product is a consumer product,
482 doubtful cases shall be resolved in favor of coverage. For a particular
483 product received by a particular user, "normally used" refers to a
484 typical or common use of that class of product, regardless of the status
485 of the particular user or of the way in which the particular user
486 actually uses, or expects or is expected to use, the product. A product
487 is a consumer product regardless of whether the product has substantial
488 commercial, industrial or non-consumer uses, unless such uses represent
489 the only significant mode of use of the product.
490
491 "Installation Information" for a User Product means any methods,
492 procedures, authorization keys, or other information required to install
493 and execute modified versions of a covered work in that User Product from
494 a modified version of its Corresponding Source. The information must
495 suffice to ensure that the continued functioning of the modified object
496 code is in no case prevented or interfered with solely because
497 modification has been made.
498
499 If you convey an object code work under this section in, or with, or
500 specifically for use in, a User Product, and the conveying occurs as
501 part of a transaction in which the right of possession and use of the
502 User Product is transferred to the recipient in perpetuity or for a
503 fixed term (regardless of how the transaction is characterized), the
504 Corresponding Source conveyed under this section must be accompanied
505 by the Installation Information. But this requirement does not apply
506 if neither you nor any third party retains the ability to install
507 modified object code on the User Product (for example, the work has
508 been installed in ROM).
509
510 The requirement to provide Installation Information does not include a
511 requirement to continue to provide support service, warranty, or updates
512 for a work that has been modified or installed by the recipient, or for
513 the User Product in which it has been modified or installed. Access to a
514 network may be denied when the modification itself materially and
515 adversely affects the operation of the network or violates the rules and
516 protocols for communication across the network.
517
518 Corresponding Source conveyed, and Installation Information provided,
519 in accord with this section must be in a format that is publicly
520 documented (and with an implementation available to the public in
521 source code form), and must require no special password or key for
522 unpacking, reading or copying.
523
524 7. Additional Terms.
525
526 "Additional permissions" are terms that supplement the terms of this
527 License by making exceptions from one or more of its conditions.
528 Additional permissions that are applicable to the entire Program shall
529 be treated as though they were included in this License, to the extent
530 that they are valid under applicable law. If additional permissions
531 apply only to part of the Program, that part may be used separately
532 under those permissions, but the entire Program remains governed by
533 this License without regard to the additional permissions.
534
535 When you convey a copy of a covered work, you may at your option
536 remove any additional permissions from that copy, or from any part of
537 it. (Additional permissions may be written to require their own
538 removal in certain cases when you modify the work.) You may place
539 additional permissions on material, added by you to a covered work,
540 for which you have or can give appropriate copyright permission.
541
542 Notwithstanding any other provision of this License, for material you
543 add to a covered work, you may (if authorized by the copyright holders of
544 that 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
570 restrictions" within the meaning of section 10. If the Program as you
571 received it, or any part of it, contains a notice stating that it is
572 governed by this License along with a term that is a further
573 restriction, you may remove that term. If a license document contains
574 a further restriction but permits relicensing or conveying under this
575 License, you may add to a covered work material governed by the terms
576 of that license document, provided that the further restriction does
577 not survive such relicensing or conveying.
578
579 If you add terms to a covered work in accord with this section, you
580 must place, in the relevant source files, a statement of the
581 additional terms that apply to those files, or a notice indicating
582 where to find the applicable terms.
583
584 Additional terms, permissive or non-permissive, may be stated in the
585 form of a separately written license, or stated as exceptions;
586 the above requirements apply either way.
587
588 8. Termination.
589
590 You may not propagate or modify a covered work except as expressly
591 provided under this License. Any attempt otherwise to propagate or
592 modify it is void, and will automatically terminate your rights under
593 this License (including any patent licenses granted under the third
594 paragraph of section 11).
595
596 However, if you cease all violation of this License, then your
597 license from a particular copyright holder is reinstated (a)
598 provisionally, unless and until the copyright holder explicitly and
599 finally terminates your license, and (b) permanently, if the copyright
600 holder fails to notify you of the violation by some reasonable means
601 prior to 60 days after the cessation.
602
603 Moreover, your license from a particular copyright holder is
604 reinstated permanently if the copyright holder notifies you of the
605 violation by some reasonable means, this is the first time you have
606 received notice of violation of this License (for any work) from that
607 copyright holder, and you cure the violation prior to 30 days after
608 your receipt of the notice.
609
610 Termination of your rights under this section does not terminate the
611 licenses of parties who have received copies or rights from you under
612 this License. If your rights have been terminated and not permanently
613 reinstated, you do not qualify to receive new licenses for the same
614 material 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
619 run a copy of the Program. Ancillary propagation of a covered work
620 occurring solely as a consequence of using peer-to-peer transmission
621 to receive a copy likewise does not require acceptance. However,
622 nothing other than this License grants you permission to propagate or
623 modify any covered work. These actions infringe copyright if you do
624 not accept this License. Therefore, by modifying or propagating a
625 covered 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
630 receives a license from the original licensors, to run, modify and
631 propagate that work, subject to this License. You are not responsible
632 for enforcing compliance by third parties with this License.
633
634 An "entity transaction" is a transaction transferring control of an
635 organization, or substantially all assets of one, or subdividing an
636 organization, or merging organizations. If propagation of a covered
637 work results from an entity transaction, each party to that
638 transaction who receives a copy of the work also receives whatever
639 licenses to the work the party's predecessor in interest had or could
640 give under the previous paragraph, plus a right to possession of the
641 Corresponding Source of the work from the predecessor in interest, if
642 the predecessor has it or can get it with reasonable efforts.
643
644 You may not impose any further restrictions on the exercise of the
645 rights granted or affirmed under this License. For example, you may
646 not impose a license fee, royalty, or other charge for exercise of
647 rights granted under this License, and you may not initiate litigation
648 (including a cross-claim or counterclaim in a lawsuit) alleging that
649 any patent claim is infringed by making, using, selling, offering for
650 sale, 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
655 License of the Program or a work on which the Program is based. The
656 work thus licensed is called the contributor's "contributor version".
657
658 A contributor's "essential patent claims" are all patent claims
659 owned or controlled by the contributor, whether already acquired or
660 hereafter acquired, that would be infringed by some manner, permitted
661 by this License, of making, using, or selling its contributor version,
662 but do not include claims that would be infringed only as a
663 consequence of further modification of the contributor version. For
664 purposes of this definition, "control" includes the right to grant
665 patent sublicenses in a manner consistent with the requirements of
666 this License.
667
668 Each contributor grants you a non-exclusive, worldwide, royalty-free
669 patent license under the contributor's essential patent claims, to
670 make, use, sell, offer for sale, import and otherwise run, modify and
671 propagate the contents of its contributor version.
672
673 In the following three paragraphs, a "patent license" is any express
674 agreement or commitment, however denominated, not to enforce a patent
675 (such as an express permission to practice a patent or covenant not to
676 sue for patent infringement). To "grant" such a patent license to a
677 party means to make such an agreement or commitment not to enforce a
678 patent against the party.
679
680 If you convey a covered work, knowingly relying on a patent license,
681 and the Corresponding Source of the work is not available for anyone
682 to copy, free of charge and under the terms of this License, through a
683 publicly available network server or other readily accessible means,
684 then you must either (1) cause the Corresponding Source to be so
685 available, or (2) arrange to deprive yourself of the benefit of the
686 patent license for this particular work, or (3) arrange, in a manner
687 consistent with the requirements of this License, to extend the patent
688 license to downstream recipients. "Knowingly relying" means you have
689 actual knowledge that, but for the patent license, your conveying the
690 covered work in a country, or your recipient's use of the covered work
691 in a country, would infringe one or more identifiable patents in that
692 country that you have reason to believe are valid.
693
694 If, pursuant to or in connection with a single transaction or
695 arrangement, you convey, or propagate by procuring conveyance of, a
696 covered work, and grant a patent license to some of the parties
697 receiving the covered work authorizing them to use, propagate, modify
698 or convey a specific copy of the covered work, then the patent license
699 you grant is automatically extended to all recipients of the covered
700 work and works based on it.
701
702 A patent license is "discriminatory" if it does not include within
703 the scope of its coverage, prohibits the exercise of, or is
704 conditioned on the non-exercise of one or more of the rights that are
705 specifically granted under this License. You may not convey a covered
706 work if you are a party to an arrangement with a third party that is
707 in the business of distributing software, under which you make payment
708 to the third party based on the extent of your activity of conveying
709 the work, and under which the third party grants, to any of the
710 parties who would receive the covered work from you, a discriminatory
711 patent license (a) in connection with copies of the covered work
712 conveyed by you (or copies made from those copies), or (b) primarily
713 for and in connection with specific products or compilations that
714 contain the covered work, unless you entered into that arrangement,
715 or that patent license was granted, prior to 28 March 2007.
716
717 Nothing in this License shall be construed as excluding or limiting
718 any implied license or other defenses to infringement that may
719 otherwise 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
724 otherwise) that contradict the conditions of this License, they do not
725 excuse you from the conditions of this License. If you cannot convey a
726 covered work so as to satisfy simultaneously your obligations under this
727 License and any other pertinent obligations, then as a consequence you may
728 not convey it at all. For example, if you agree to terms that obligate you
729 to collect a royalty for further conveying from those to whom you convey
730 the Program, the only way you could satisfy both those terms and this
731 License 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
736 permission to link or combine any covered work with a work licensed
737 under version 3 of the GNU Affero General Public License into a single
738 combined work, and to convey the resulting work. The terms of this
739 License will continue to apply to the part which is the covered work,
740 but the special requirements of the GNU Affero General Public License,
741 section 13, concerning interaction through a network will apply to the
742 combination as such.
743
744 14. Revised Versions of this License.
745
746 The Free Software Foundation may publish revised and/or new versions of
747 the GNU General Public License from time to time. Such new versions will
748 be similar in spirit to the present version, but may differ in detail to
749 address new problems or concerns.
750
751 Each version is given a distinguishing version number. If the
752 Program specifies that a certain numbered version of the GNU General
753 Public License "or any later version" applies to it, you have the
754 option of following the terms and conditions either of that numbered
755 version or of any later version published by the Free Software
756 Foundation. If the Program does not specify a version number of the
757 GNU General Public License, you may choose any version ever published
758 by the Free Software Foundation.
759
760 If the Program specifies that a proxy can decide which future
761 versions of the GNU General Public License can be used, that proxy's
762 public statement of acceptance of a version permanently authorizes you
763 to choose that version for the Program.
764
765 Later license versions may give you additional or different
766 permissions. However, no additional obligations are imposed on any
767 author or copyright holder as a result of your choosing to follow a
768 later version.
769
770 15. Disclaimer of Warranty.
771
772 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
773 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
774 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
775 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
776 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
777 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
778 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
779 ALL 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
784 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
785 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
786 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
787 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
788 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
789 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
790 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
791 SUCH DAMAGES.
792
793 17. Interpretation of Sections 15 and 16.
794
795 If the disclaimer of warranty and limitation of liability provided
796 above cannot be given local legal effect according to their terms,
797 reviewing courts shall apply local law that most closely approximates
798 an absolute waiver of all civil liability in connection with the
799 Program, unless a warranty or assumption of liability accompanies a
800 copy of the Program in return for a fee.
801
802 END OF TERMS AND CONDITIONS
803
804 How to Apply These Terms to Your New Programs
805
806 If you develop a new program, and you want it to be of the greatest
807 possible use to the public, the best way to achieve this is to make it
808 free 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
811 to attach them to the start of each source file to most effectively
812 state the exclusion of warranty; and each file should have at least
813 the "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
831 Also 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
834 notice 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
841 The hypothetical commands `show w' and `show c' should show the appropriate
842 parts of the General Public License. Of course, your program's commands
843 might 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,
846 if any, to sign a "copyright disclaimer" for the program, if necessary.
847 For 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
851 into proprietary programs. If your program is a subroutine library, you
852 may consider it more useful to permit linking proprietary applications with
853 the library. If this is what you want to do, use the GNU Lesser General
854 Public License instead of this License. But first, please read
855 <http://www.gnu.org/philosophy/why-not-lgpl.html>.
