6 Everyone is permitted to copy and distribute verbatim copies
7 of this license document, but changing it is not allowed.
11 The licenses for most software are designed to take away your
12 freedom to share and change it. By contrast, the GNU General Public
13 License is intended to guarantee your freedom to share and change free
14 software--to make sure the software is free for all its users. This
15 General Public License applies to most of the Free Software
16 Foundation's software and to any other program whose authors commit to
17 using it. (Some other Free Software Foundation software is covered by
18 the GNU Lesser General Public License instead.) You can apply it to
21 When we speak of free software, we are referring to freedom, not
22 price. Our General Public Licenses are designed to make sure that you
23 have the freedom to distribute copies of free software (and charge for
24 this service if you wish), that you receive source code or can get it
25 if you want it, that you can change the software or use pieces of it
26 in new free programs; and that you know you can do these things.
28 To protect your rights, we need to make restrictions that forbid
29 anyone to deny you these rights or to ask you to surrender the rights.
30 These restrictions translate to certain responsibilities for you if you
31 distribute copies of the software, or if you modify it.
33 For example, if you distribute copies of such a program, whether
34 gratis or for a fee, you must give the recipients all the rights that
35 you have. You must make sure that they, too, receive or can get the
36 source code. And you must show them these terms so they know their
39 We protect your rights with two steps: (1) copyright the software, and
40 (2) offer you this license which gives you legal permission to copy,
41 distribute and/or modify the software.
43 Also, for each author's protection and ours, we want to make certain
44 that everyone understands that there is no warranty for this free
45 software. If the software is modified by someone else and passed on, we
46 want its recipients to know that what they have is not the original, so
47 that any problems introduced by others will not reflect on the original
50 Finally, any free program is threatened constantly by software
51 patents. We wish to avoid the danger that redistributors of a free
52 program will individually obtain patent licenses, in effect making the
53 program proprietary. To prevent this, we have made it clear that any
54 patent must be licensed for everyone's free use or not licensed at all.
56 The precise terms and conditions for copying, distribution and
59 GNU GENERAL PUBLIC LICENSE
60 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
62 0. This License applies to any program or other work which contains
63 a notice placed by the copyright holder saying it may be distributed
64 under the terms of this General Public License. The "Program", below,
65 refers to any such program or work, and a "work based on the Program"
66 means either the Program or any derivative work under copyright law:
67 that is to say, a work containing the Program or a portion of it,
68 either verbatim or with modifications and/or translated into another
69 language. (Hereinafter, translation is included without limitation in
70 the term "modification".) Each licensee is addressed as "you".
72 Activities other than copying, distribution and modification are not
73 covered by this License; they are outside its scope. The act of
74 running the Program is not restricted, and the output from the Program
75 is covered only if its contents constitute a work based on the
76 Program (independent of having been made by running the Program).
77 Whether that is true depends on what the Program does.
79 1. You may copy and distribute verbatim copies of the Program's
80 source code as you receive it, in any medium, provided that you
81 conspicuously and appropriately publish on each copy an appropriate
82 copyright notice and disclaimer of warranty; keep intact all the
83 notices that refer to this License and to the absence of any warranty;
84 and give any other recipients of the Program a copy of this License
85 along with the Program.
87 You may charge a fee for the physical act of transferring a copy, and
88 you may at your option offer warranty protection in exchange for a fee.
90 2. You may modify your copy or copies of the Program or any portion
91 of it, thus forming a work based on the Program, and copy and
92 distribute such modifications or work under the terms of Section 1
93 above, provided that you also meet all of these conditions:
95 a) You must cause the modified files to carry prominent notices
96 stating that you changed the files and the date of any change.
98 b) You must cause any work that you distribute or publish, that in
99 whole or in part contains or is derived from the Program or any
100 part thereof, to be licensed as a whole at no charge to all third
101 parties under the terms of this License.
103 c) If the modified program normally reads commands interactively
104 when run, you must cause it, when started running for such
105 interactive use in the most ordinary way, to print or display an
106 announcement including an appropriate copyright notice and a
107 notice that there is no warranty (or else, saying that you provide
108 a warranty) and that users may redistribute the program under
109 these conditions, and telling the user how to view a copy of this
110 License. (Exception: if the Program itself is interactive but
111 does not normally print such an announcement, your work based on
112 the Program is not required to print an announcement.)
114 These requirements apply to the modified work as a whole. If
115 identifiable sections of that work are not derived from the Program,
116 and can be reasonably considered independent and separate works in
117 themselves, then this License, and its terms, do not apply to those
118 sections when you distribute them as separate works. But when you
119 distribute the same sections as part of a whole which is a work based
120 on the Program, the distribution of the whole must be on the terms of
121 this License, whose permissions for other licensees extend to the
122 entire whole, and thus to each and every part regardless of who wrote it.
124 Thus, it is not the intent of this section to claim rights or contest
125 your rights to work written entirely by you; rather, the intent is to
126 exercise the right to control the distribution of derivative or
127 collective works based on the Program.
129 In addition, mere aggregation of another work not based on the Program
130 with the Program (or with a work based on the Program) on a volume of
131 a storage or distribution medium does not bring the other work under
132 the scope of this License.
134 3. You may copy and distribute the Program (or a work based on it,
135 under Section 2) in object code or executable form under the terms of
136 Sections 1 and 2 above provided that you also do one of the following:
138 a) Accompany it with the complete corresponding machine-readable
139 source code, which must be distributed under the terms of Sections
140 1 and 2 above on a medium customarily used for software interchange; or,
142 b) Accompany it with a written offer, valid for at least three
143 years, to give any third party, for a charge no more than your
144 cost of physically performing source distribution, a complete
145 machine-readable copy of the corresponding source code, to be
146 distributed under the terms of Sections 1 and 2 above on a medium
147 customarily used for software interchange; or,
149 c) Accompany it with the information you received as to the offer
150 to distribute corresponding source code. (This alternative is
151 allowed only for noncommercial distribution and only if you
152 received the program in object code or executable form with such
153 an offer, in accord with Subsection b above.)
155 The source code for a work means the preferred form of the work for
156 making modifications to it. For an executable work, complete source
157 code means all the source code for all modules it contains, plus any
158 associated interface definition files, plus the scripts used to
159 control compilation and installation of the executable. However, as a
160 special exception, the source code distributed need not include
161 anything that is normally distributed (in either source or binary
162 form) with the major components (compiler, kernel, and so on) of the
163 operating system on which the executable runs, unless that component
164 itself accompanies the executable.
166 If distribution of executable or object code is made by offering
167 access to copy from a designated place, then offering equivalent
168 access to copy the source code from the same place counts as
169 distribution of the source code, even though third parties are not
170 compelled to copy the source along with the object code.
172 4. You may not copy, modify, sublicense, or distribute the Program
173 except as expressly provided under this License. Any attempt
174 otherwise to copy, modify, sublicense or distribute the Program is
175 void, and will automatically terminate your rights under this License.
176 However, parties who have received copies, or rights, from you under
177 this License will not have their licenses terminated so long as such
178 parties remain in full compliance.
180 5. You are not required to accept this License, since you have not
181 signed it. However, nothing else grants you permission to modify or
182 distribute the Program or its derivative works. These actions are
183 prohibited by law if you do not accept this License. Therefore, by
184 modifying or distributing the Program (or any work based on the
185 Program), you indicate your acceptance of this License to do so, and
186 all its terms and conditions for copying, distributing or modifying
187 the Program or works based on it.
189 6. Each time you redistribute the Program (or any work based on the
190 Program), the recipient automatically receives a license from the
191 original licensor to copy, distribute or modify the Program subject to
192 these terms and conditions. You may not impose any further
193 restrictions on the recipients' exercise of the rights granted herein.
194 You are not responsible for enforcing compliance by third parties to
197 7. If, as a consequence of a court judgment or allegation of patent
198 infringement or for any other reason (not limited to patent issues),
199 conditions are imposed on you (whether by court order, agreement or
200 otherwise) that contradict the conditions of this License, they do not
201 excuse you from the conditions of this License. If you cannot
202 distribute so as to satisfy simultaneously your obligations under this
203 License and any other pertinent obligations, then as a consequence you
204 may not distribute the Program at all. For example, if a patent
205 license would not permit royalty-free redistribution of the Program by
206 all those who receive copies directly or indirectly through you, then
207 the only way you could satisfy both it and this License would be to
208 refrain entirely from distribution of the Program.
210 If any portion of this section is held invalid or unenforceable under
211 any particular circumstance, the balance of the section is intended to
212 apply and the section as a whole is intended to apply in other
215 It is not the purpose of this section to induce you to infringe any
216 patents or other property right claims or to contest validity of any
217 such claims; this section has the sole purpose of protecting the
218 integrity of the free software distribution system, which is
219 implemented by public license practices. Many people have made
220 generous contributions to the wide range of software distributed
221 through that system in reliance on consistent application of that
222 system; it is up to the author/donor to decide if he or she is willing
223 to distribute software through any other system and a licensee cannot
226 This section is intended to make thoroughly clear what is believed to
227 be a consequence of the rest of this License.
229 8. If the distribution and/or use of the Program is restricted in
230 certain countries either by patents or by copyrighted interfaces, the
231 original copyright holder who places the Program under this License
232 may add an explicit geographical distribution limitation excluding
233 those countries, so that distribution is permitted only in or among
234 countries not thus excluded. In such case, this License incorporates
235 the limitation as if written in the body of this License.
237 9. The Free Software Foundation may publish revised and/or new versions
238 of the General Public License from time to time. Such new versions will
239 be similar in spirit to the present version, but may differ in detail to
240 address new problems or concerns.
242 Each version is given a distinguishing version number. If the Program
243 specifies a version number of this License which applies to it and "any
244 later version", you have the option of following the terms and conditions
245 either of that version or of any later version published by the Free
246 Software Foundation. If the Program does not specify a version number of
247 this License, you may choose any version ever published by the Free Software
250 10. If you wish to incorporate parts of the Program into other free
251 programs whose distribution conditions are different, write to the author
252 to ask for permission. For software which is copyrighted by the Free
253 Software Foundation, write to the Free Software Foundation; we sometimes
254 make exceptions for this. Our decision will be guided by the two goals
255 of preserving the free status of all derivatives of our free software and
256 of promoting the sharing and reuse of software generally.
260 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
261 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
262 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
263 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
264 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
265 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
266 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
267 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
268 REPAIR OR CORRECTION.
270 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
271 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
272 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
273 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
274 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
275 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
276 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
277 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
278 POSSIBILITY OF SUCH DAMAGES.
280 END OF TERMS AND CONDITIONS
282 How to Apply These Terms to Your New Programs
284 If you develop a new program, and you want it to be of the greatest
285 possible use to the public, the best way to achieve this is to make it
286 free software which everyone can redistribute and change under these terms.
288 To do so, attach the following notices to the program. It is safest
289 to attach them to the start of each source file to most effectively
290 convey the exclusion of warranty; and each file should have at least
291 the "copyright" line and a pointer to where the full notice is found.
293 <one line to give the program's name and a brief idea of what it does.>
294 Copyright (C) <year> <name of author>
296 This program is free software; you can redistribute it and/or modify
297 it under the terms of the GNU General Public License as published by
298 the Free Software Foundation; either version 2 of the License, or
299 (at your option) any later version.
301 This program is distributed in the hope that it will be useful,
302 but WITHOUT ANY WARRANTY; without even the implied warranty of
303 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
304 GNU General Public License for more details.
306 You should have received a copy of the GNU General Public License along
307 with this program; if not, write to the Free Software Foundation, Inc.,
308 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
310 Also add information on how to contact you by electronic and paper mail.
312 If the program is interactive, make it output a short notice like this
313 when it starts in an interactive mode:
315 Gnomovision version 69, Copyright (C) year name of author
316 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
317 This is free software, and you are welcome to redistribute it
318 under certain conditions; type `show c' for details.
320 The hypothetical commands `show w' and `show c' should show the appropriate
321 parts of the General Public License. Of course, the commands you use may
322 be called something other than `show w' and `show c'; they could even be
323 mouse-clicks or menu items--whatever suits your program.
325 You should also get your employer (if you work as a programmer) or your
326 school, if any, to sign a "copyright disclaimer" for the program, if
327 necessary. Here is a sample; alter the names:
329 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
330 `Gnomovision' (which makes passes at compilers) written by James Hacker.
332 <signature of Ty Coon>, 1 April 1989
333 Ty Coon, President of Vice
335 This General Public License does not permit incorporating your program into
336 proprietary programs. If your program is a subroutine library, you may
337 consider it more useful to permit linking proprietary applications with the
338 library. If this is what you want to do, use the GNU Lesser General
339 Public License instead of this License.
340 GNU GENERAL PUBLIC LICENSE
341 Version 3, 29 June 2007
343 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
344 Everyone is permitted to copy and distribute verbatim copies
345 of this license document, but changing it is not allowed.
349 The GNU General Public License is a free, copyleft license for
350 software and other kinds of works.
352 The licenses for most software and other practical works are designed
353 to take away your freedom to share and change the works. By contrast,
354 the GNU General Public License is intended to guarantee your freedom to
355 share and change all versions of a program--to make sure it remains free
356 software for all its users. We, the Free Software Foundation, use the
357 GNU General Public License for most of our software; it applies also to
358 any other work released this way by its authors. You can apply it to
361 When we speak of free software, we are referring to freedom, not
362 price. Our General Public Licenses are designed to make sure that you
363 have the freedom to distribute copies of free software (and charge for
364 them if you wish), that you receive source code or can get it if you
365 want it, that you can change the software or use pieces of it in new
366 free programs, and that you know you can do these things.
368 To protect your rights, we need to prevent others from denying you
369 these rights or asking you to surrender the rights. Therefore, you have
370 certain responsibilities if you distribute copies of the software, or if
371 you modify it: responsibilities to respect the freedom of others.
373 For example, if you distribute copies of such a program, whether
374 gratis or for a fee, you must pass on to the recipients the same
375 freedoms that you received. You must make sure that they, too, receive
376 or can get the source code. And you must show them these terms so they
379 Developers that use the GNU GPL protect your rights with two steps:
380 (1) assert copyright on the software, and (2) offer you this License
381 giving you legal permission to copy, distribute and/or modify it.
383 For the developers' and authors' protection, the GPL clearly explains
384 that there is no warranty for this free software. For both users' and
385 authors' sake, the GPL requires that modified versions be marked as
386 changed, so that their problems will not be attributed erroneously to
387 authors of previous versions.
389 Some devices are designed to deny users access to install or run
390 modified versions of the software inside them, although the manufacturer
391 can do so. This is fundamentally incompatible with the aim of
392 protecting users' freedom to change the software. The systematic
393 pattern of such abuse occurs in the area of products for individuals to
394 use, which is precisely where it is most unacceptable. Therefore, we
395 have designed this version of the GPL to prohibit the practice for those
396 products. If such problems arise substantially in other domains, we
397 stand ready to extend this provision to those domains in future versions
398 of the GPL, as needed to protect the freedom of users.
400 Finally, every program is threatened constantly by software patents.
401 States should not allow patents to restrict development and use of
402 software on general-purpose computers, but in those that do, we wish to
403 avoid the special danger that patents applied to a free program could
404 make it effectively proprietary. To prevent this, the GPL assures that
405 patents cannot be used to render the program non-free.
407 The precise terms and conditions for copying, distribution and
414 "This License" refers to version 3 of the GNU General Public License.
416 "Copyright" also means copyright-like laws that apply to other kinds of
417 works, such as semiconductor masks.
419 "The Program" refers to any copyrightable work licensed under this
420 License. Each licensee is addressed as "you". "Licensees" and
421 "recipients" may be individuals or organizations.
423 To "modify" a work means to copy from or adapt all or part of the work
424 in a fashion requiring copyright permission, other than the making of an
425 exact copy. The resulting work is called a "modified version" of the
426 earlier work or a work "based on" the earlier work.
428 A "covered work" means either the unmodified Program or a work based
431 To "propagate" a work means to do anything with it that, without
432 permission, would make you directly or secondarily liable for
433 infringement under applicable copyright law, except executing it on a
434 computer or modifying a private copy. Propagation includes copying,
435 distribution (with or without modification), making available to the
436 public, and in some countries other activities as well.
438 To "convey" a work means any kind of propagation that enables other
439 parties to make or receive copies. Mere interaction with a user through
440 a computer network, with no transfer of a copy, is not conveying.
442 An interactive user interface displays "Appropriate Legal Notices"
443 to the extent that it includes a convenient and prominently visible
444 feature that (1) displays an appropriate copyright notice, and (2)
445 tells the user that there is no warranty for the work (except to the
446 extent that warranties are provided), that licensees may convey the
447 work under this License, and how to view a copy of this License. If
448 the interface presents a list of user commands or options, such as a
449 menu, a prominent item in the list meets this criterion.
453 The "source code" for a work means the preferred form of the work
454 for making modifications to it. "Object code" means any non-source
457 A "Standard Interface" means an interface that either is an official
458 standard defined by a recognized standards body, or, in the case of
459 interfaces specified for a particular programming language, one that
460 is widely used among developers working in that language.
462 The "System Libraries" of an executable work include anything, other
463 than the work as a whole, that (a) is included in the normal form of
464 packaging a Major Component, but which is not part of that Major
465 Component, and (b) serves only to enable use of the work with that
466 Major Component, or to implement a Standard Interface for which an
467 implementation is available to the public in source code form. A
468 "Major Component", in this context, means a major essential component
469 (kernel, window system, and so on) of the specific operating system
470 (if any) on which the executable work runs, or a compiler used to
471 produce the work, or an object code interpreter used to run it.
473 The "Corresponding Source" for a work in object code form means all
474 the source code needed to generate, install, and (for an executable
475 work) run the object code and to modify the work, including scripts to
476 control those activities. However, it does not include the work's
477 System Libraries, or general-purpose tools or generally available free
478 programs which are used unmodified in performing those activities but
479 which are not part of the work. For example, Corresponding Source
480 includes interface definition files associated with source files for
481 the work, and the source code for shared libraries and dynamically
482 linked subprograms that the work is specifically designed to require,
483 such as by intimate data communication or control flow between those
484 subprograms and other parts of the work.
486 The Corresponding Source need not include anything that users
487 can regenerate automatically from other parts of the Corresponding
490 The Corresponding Source for a work in source code form is that
493 2. Basic Permissions.
495 All rights granted under this License are granted for the term of
496 copyright on the Program, and are irrevocable provided the stated
497 conditions are met. This License explicitly affirms your unlimited
498 permission to run the unmodified Program. The output from running a
499 covered work is covered by this License only if the output, given its
500 content, constitutes a covered work. This License acknowledges your
501 rights of fair use or other equivalent, as provided by copyright law.
503 You may make, run and propagate covered works that you do not
504 convey, without conditions so long as your license otherwise remains
505 in force. You may convey covered works to others for the sole purpose
506 of having them make modifications exclusively for you, or provide you
507 with facilities for running those works, provided that you comply with
508 the terms of this License in conveying all material for which you do
509 not control copyright. Those thus making or running the covered works
510 for you must do so exclusively on your behalf, under your direction
511 and control, on terms that prohibit them from making any copies of
512 your copyrighted material outside their relationship with you.
514 Conveying under any other circumstances is permitted solely under
515 the conditions stated below. Sublicensing is not allowed; section 10
516 makes it unnecessary.
518 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
520 No covered work shall be deemed part of an effective technological
521 measure under any applicable law fulfilling obligations under article
522 11 of the WIPO copyright treaty adopted on 20 December 1996, or
523 similar laws prohibiting or restricting circumvention of such
526 When you convey a covered work, you waive any legal power to forbid
527 circumvention of technological measures to the extent such circumvention
528 is effected by exercising rights under this License with respect to
529 the covered work, and you disclaim any intention to limit operation or
530 modification of the work as a means of enforcing, against the work's
531 users, your or third parties' legal rights to forbid circumvention of
532 technological measures.
534 4. Conveying Verbatim Copies.
536 You may convey verbatim copies of the Program's source code as you
537 receive it, in any medium, provided that you conspicuously and
538 appropriately publish on each copy an appropriate copyright notice;
539 keep intact all notices stating that this License and any
540 non-permissive terms added in accord with section 7 apply to the code;
541 keep intact all notices of the absence of any warranty; and give all
542 recipients a copy of this License along with the Program.
544 You may charge any price or no price for each copy that you convey,
545 and you may offer support or warranty protection for a fee.
547 5. Conveying Modified Source Versions.
549 You may convey a work based on the Program, or the modifications to
550 produce it from the Program, in the form of source code under the
551 terms of section 4, provided that you also meet all of these conditions:
553 a) The work must carry prominent notices stating that you modified
554 it, and giving a relevant date.
556 b) The work must carry prominent notices stating that it is
557 released under this License and any conditions added under section
558 7. This requirement modifies the requirement in section 4 to
559 "keep intact all notices".
561 c) You must license the entire work, as a whole, under this
562 License to anyone who comes into possession of a copy. This
563 License will therefore apply, along with any applicable section 7
564 additional terms, to the whole of the work, and all its parts,
565 regardless of how they are packaged. This License gives no
566 permission to license the work in any other way, but it does not
567 invalidate such permission if you have separately received it.
569 d) If the work has interactive user interfaces, each must display
570 Appropriate Legal Notices; however, if the Program has interactive
571 interfaces that do not display Appropriate Legal Notices, your
572 work need not make them do so.
574 A compilation of a covered work with other separate and independent
575 works, which are not by their nature extensions of the covered work,
576 and which are not combined with it such as to form a larger program,
577 in or on a volume of a storage or distribution medium, is called an
578 "aggregate" if the compilation and its resulting copyright are not
579 used to limit the access or legal rights of the compilation's users
580 beyond what the individual works permit. Inclusion of a covered work
581 in an aggregate does not cause this License to apply to the other
582 parts of the aggregate.
584 6. Conveying Non-Source Forms.
586 You may convey a covered work in object code form under the terms
587 of sections 4 and 5, provided that you also convey the
588 machine-readable Corresponding Source under the terms of this License,
589 in one of these ways:
591 a) Convey the object code in, or embodied in, a physical product
592 (including a physical distribution medium), accompanied by the
593 Corresponding Source fixed on a durable physical medium
594 customarily used for software interchange.
596 b) Convey the object code in, or embodied in, a physical product
597 (including a physical distribution medium), accompanied by a
598 written offer, valid for at least three years and valid for as
599 long as you offer spare parts or customer support for that product
600 model, to give anyone who possesses the object code either (1) a
601 copy of the Corresponding Source for all the software in the
602 product that is covered by this License, on a durable physical
603 medium customarily used for software interchange, for a price no
604 more than your reasonable cost of physically performing this
605 conveying of source, or (2) access to copy the
606 Corresponding Source from a network server at no charge.
608 c) Convey individual copies of the object code with a copy of the
609 written offer to provide the Corresponding Source. This
610 alternative is allowed only occasionally and noncommercially, and
611 only if you received the object code with such an offer, in accord
614 d) Convey the object code by offering access from a designated
615 place (gratis or for a charge), and offer equivalent access to the
616 Corresponding Source in the same way through the same place at no
617 further charge. You need not require recipients to copy the
618 Corresponding Source along with the object code. If the place to
619 copy the object code is a network server, the Corresponding Source
620 may be on a different server (operated by you or a third party)
621 that supports equivalent copying facilities, provided you maintain
622 clear directions next to the object code saying where to find the
623 Corresponding Source. Regardless of what server hosts the
624 Corresponding Source, you remain obligated to ensure that it is
625 available for as long as needed to satisfy these requirements.
627 e) Convey the object code using peer-to-peer transmission, provided
628 you inform other peers where the object code and Corresponding
629 Source of the work are being offered to the general public at no
630 charge under subsection 6d.
632 A separable portion of the object code, whose source code is excluded
633 from the Corresponding Source as a System Library, need not be
634 included in conveying the object code work.
636 A "User Product" is either (1) a "consumer product", which means any
637 tangible personal property which is normally used for personal, family,
638 or household purposes, or (2) anything designed or sold for incorporation
639 into a dwelling. In determining whether a product is a consumer product,
640 doubtful cases shall be resolved in favor of coverage. For a particular
641 product received by a particular user, "normally used" refers to a
642 typical or common use of that class of product, regardless of the status
643 of the particular user or of the way in which the particular user
644 actually uses, or expects or is expected to use, the product. A product
645 is a consumer product regardless of whether the product has substantial
646 commercial, industrial or non-consumer uses, unless such uses represent
647 the only significant mode of use of the product.
649 "Installation Information" for a User Product means any methods,
650 procedures, authorization keys, or other information required to install
651 and execute modified versions of a covered work in that User Product from
652 a modified version of its Corresponding Source. The information must
653 suffice to ensure that the continued functioning of the modified object
654 code is in no case prevented or interfered with solely because
655 modification has been made.
657 If you convey an object code work under this section in, or with, or
658 specifically for use in, a User Product, and the conveying occurs as
659 part of a transaction in which the right of possession and use of the
660 User Product is transferred to the recipient in perpetuity or for a
661 fixed term (regardless of how the transaction is characterized), the
662 Corresponding Source conveyed under this section must be accompanied
663 by the Installation Information. But this requirement does not apply
664 if neither you nor any third party retains the ability to install
665 modified object code on the User Product (for example, the work has
666 been installed in ROM).
668 The requirement to provide Installation Information does not include a
669 requirement to continue to provide support service, warranty, or updates
670 for a work that has been modified or installed by the recipient, or for
671 the User Product in which it has been modified or installed. Access to a
672 network may be denied when the modification itself materially and
673 adversely affects the operation of the network or violates the rules and
674 protocols for communication across the network.
676 Corresponding Source conveyed, and Installation Information provided,
677 in accord with this section must be in a format that is publicly
678 documented (and with an implementation available to the public in
679 source code form), and must require no special password or key for
680 unpacking, reading or copying.
684 "Additional permissions" are terms that supplement the terms of this
685 License by making exceptions from one or more of its conditions.
686 Additional permissions that are applicable to the entire Program shall
687 be treated as though they were included in this License, to the extent
688 that they are valid under applicable law. If additional permissions
689 apply only to part of the Program, that part may be used separately
690 under those permissions, but the entire Program remains governed by
691 this License without regard to the additional permissions.
693 When you convey a copy of a covered work, you may at your option
694 remove any additional permissions from that copy, or from any part of
695 it. (Additional permissions may be written to require their own
696 removal in certain cases when you modify the work.) You may place
697 additional permissions on material, added by you to a covered work,
698 for which you have or can give appropriate copyright permission.
700 Notwithstanding any other provision of this License, for material you
701 add to a covered work, you may (if authorized by the copyright holders of
702 that material) supplement the terms of this License with terms:
704 a) Disclaiming warranty or limiting liability differently from the
705 terms of sections 15 and 16 of this License; or
707 b) Requiring preservation of specified reasonable legal notices or
708 author attributions in that material or in the Appropriate Legal
709 Notices displayed by works containing it; or
711 c) Prohibiting misrepresentation of the origin of that material, or
712 requiring that modified versions of such material be marked in
713 reasonable ways as different from the original version; or
715 d) Limiting the use for publicity purposes of names of licensors or
716 authors of the material; or
718 e) Declining to grant rights under trademark law for use of some
719 trade names, trademarks, or service marks; or
721 f) Requiring indemnification of licensors and authors of that
722 material by anyone who conveys the material (or modified versions of
723 it) with contractual assumptions of liability to the recipient, for
724 any liability that these contractual assumptions directly impose on
725 those licensors and authors.
727 All other non-permissive additional terms are considered "further
728 restrictions" within the meaning of section 10. If the Program as you
729 received it, or any part of it, contains a notice stating that it is
730 governed by this License along with a term that is a further
731 restriction, you may remove that term. If a license document contains
732 a further restriction but permits relicensing or conveying under this
733 License, you may add to a covered work material governed by the terms
734 of that license document, provided that the further restriction does
735 not survive such relicensing or conveying.
737 If you add terms to a covered work in accord with this section, you
738 must place, in the relevant source files, a statement of the
739 additional terms that apply to those files, or a notice indicating
740 where to find the applicable terms.
742 Additional terms, permissive or non-permissive, may be stated in the
743 form of a separately written license, or stated as exceptions;
744 the above requirements apply either way.
748 You may not propagate or modify a covered work except as expressly
749 provided under this License. Any attempt otherwise to propagate or
750 modify it is void, and will automatically terminate your rights under
751 this License (including any patent licenses granted under the third
752 paragraph of section 11).
754 However, if you cease all violation of this License, then your
755 license from a particular copyright holder is reinstated (a)
756 provisionally, unless and until the copyright holder explicitly and
757 finally terminates your license, and (b) permanently, if the copyright
758 holder fails to notify you of the violation by some reasonable means
759 prior to 60 days after the cessation.
761 Moreover, your license from a particular copyright holder is
762 reinstated permanently if the copyright holder notifies you of the
763 violation by some reasonable means, this is the first time you have
764 received notice of violation of this License (for any work) from that
765 copyright holder, and you cure the violation prior to 30 days after
766 your receipt of the notice.
768 Termination of your rights under this section does not terminate the
769 licenses of parties who have received copies or rights from you under
770 this License. If your rights have been terminated and not permanently
771 reinstated, you do not qualify to receive new licenses for the same
772 material under section 10.
774 9. Acceptance Not Required for Having Copies.
776 You are not required to accept this License in order to receive or
777 run a copy of the Program. Ancillary propagation of a covered work
778 occurring solely as a consequence of using peer-to-peer transmission
779 to receive a copy likewise does not require acceptance. However,
780 nothing other than this License grants you permission to propagate or
781 modify any covered work. These actions infringe copyright if you do
782 not accept this License. Therefore, by modifying or propagating a
783 covered work, you indicate your acceptance of this License to do so.
785 10. Automatic Licensing of Downstream Recipients.
787 Each time you convey a covered work, the recipient automatically
788 receives a license from the original licensors, to run, modify and
789 propagate that work, subject to this License. You are not responsible
790 for enforcing compliance by third parties with this License.
792 An "entity transaction" is a transaction transferring control of an
793 organization, or substantially all assets of one, or subdividing an
794 organization, or merging organizations. If propagation of a covered
795 work results from an entity transaction, each party to that
796 transaction who receives a copy of the work also receives whatever
797 licenses to the work the party's predecessor in interest had or could
798 give under the previous paragraph, plus a right to possession of the
799 Corresponding Source of the work from the predecessor in interest, if
800 the predecessor has it or can get it with reasonable efforts.
802 You may not impose any further restrictions on the exercise of the
803 rights granted or affirmed under this License. For example, you may
804 not impose a license fee, royalty, or other charge for exercise of
805 rights granted under this License, and you may not initiate litigation
806 (including a cross-claim or counterclaim in a lawsuit) alleging that
807 any patent claim is infringed by making, using, selling, offering for
808 sale, or importing the Program or any portion of it.
812 A "contributor" is a copyright holder who authorizes use under this
813 License of the Program or a work on which the Program is based. The
814 work thus licensed is called the contributor's "contributor version".
816 A contributor's "essential patent claims" are all patent claims
817 owned or controlled by the contributor, whether already acquired or
818 hereafter acquired, that would be infringed by some manner, permitted
819 by this License, of making, using, or selling its contributor version,
820 but do not include claims that would be infringed only as a
821 consequence of further modification of the contributor version. For
822 purposes of this definition, "control" includes the right to grant
823 patent sublicenses in a manner consistent with the requirements of
826 Each contributor grants you a non-exclusive, worldwide, royalty-free
827 patent license under the contributor's essential patent claims, to
828 make, use, sell, offer for sale, import and otherwise run, modify and
829 propagate the contents of its contributor version.
831 In the following three paragraphs, a "patent license" is any express
832 agreement or commitment, however denominated, not to enforce a patent
833 (such as an express permission to practice a patent or covenant not to
834 sue for patent infringement). To "grant" such a patent license to a
835 party means to make such an agreement or commitment not to enforce a
836 patent against the party.
838 If you convey a covered work, knowingly relying on a patent license,
839 and the Corresponding Source of the work is not available for anyone
840 to copy, free of charge and under the terms of this License, through a
841 publicly available network server or other readily accessible means,
842 then you must either (1) cause the Corresponding Source to be so
843 available, or (2) arrange to deprive yourself of the benefit of the
844 patent license for this particular work, or (3) arrange, in a manner
845 consistent with the requirements of this License, to extend the patent
846 license to downstream recipients. "Knowingly relying" means you have
847 actual knowledge that, but for the patent license, your conveying the
848 covered work in a country, or your recipient's use of the covered work
849 in a country, would infringe one or more identifiable patents in that
850 country that you have reason to believe are valid.
852 If, pursuant to or in connection with a single transaction or
853 arrangement, you convey, or propagate by procuring conveyance of, a
854 covered work, and grant a patent license to some of the parties
855 receiving the covered work authorizing them to use, propagate, modify
856 or convey a specific copy of the covered work, then the patent license
857 you grant is automatically extended to all recipients of the covered
858 work and works based on it.
860 A patent license is "discriminatory" if it does not include within
861 the scope of its coverage, prohibits the exercise of, or is
862 conditioned on the non-exercise of one or more of the rights that are
863 specifically granted under this License. You may not convey a covered
864 work if you are a party to an arrangement with a third party that is
865 in the business of distributing software, under which you make payment
866 to the third party based on the extent of your activity of conveying
867 the work, and under which the third party grants, to any of the
868 parties who would receive the covered work from you, a discriminatory
869 patent license (a) in connection with copies of the covered work
870 conveyed by you (or copies made from those copies), or (b) primarily
871 for and in connection with specific products or compilations that
872 contain the covered work, unless you entered into that arrangement,
873 or that patent license was granted, prior to 28 March 2007.
875 Nothing in this License shall be construed as excluding or limiting
876 any implied license or other defenses to infringement that may
877 otherwise be available to you under applicable patent law.
879 12. No Surrender of Others' Freedom.
881 If conditions are imposed on you (whether by court order, agreement or
882 otherwise) that contradict the conditions of this License, they do not
883 excuse you from the conditions of this License. If you cannot convey a
884 covered work so as to satisfy simultaneously your obligations under this
885 License and any other pertinent obligations, then as a consequence you may
886 not convey it at all. For example, if you agree to terms that obligate you
887 to collect a royalty for further conveying from those to whom you convey
888 the Program, the only way you could satisfy both those terms and this
889 License would be to refrain entirely from conveying the Program.
891 13. Use with the GNU Affero General Public License.
893 Notwithstanding any other provision of this License, you have
894 permission to link or combine any covered work with a work licensed
895 under version 3 of the GNU Affero General Public License into a single
896 combined work, and to convey the resulting work. The terms of this
897 License will continue to apply to the part which is the covered work,
898 but the special requirements of the GNU Affero General Public License,
899 section 13, concerning interaction through a network will apply to the
902 14. Revised Versions of this License.
904 The Free Software Foundation may publish revised and/or new versions of
905 the GNU General Public License from time to time. Such new versions will
906 be similar in spirit to the present version, but may differ in detail to
907 address new problems or concerns.
909 Each version is given a distinguishing version number. If the
910 Program specifies that a certain numbered version of the GNU General
911 Public License "or any later version" applies to it, you have the
912 option of following the terms and conditions either of that numbered
913 version or of any later version published by the Free Software
914 Foundation. If the Program does not specify a version number of the
915 GNU General Public License, you may choose any version ever published
916 by the Free Software Foundation.
918 If the Program specifies that a proxy can decide which future
919 versions of the GNU General Public License can be used, that proxy's
920 public statement of acceptance of a version permanently authorizes you
921 to choose that version for the Program.
923 Later license versions may give you additional or different
924 permissions. However, no additional obligations are imposed on any
925 author or copyright holder as a result of your choosing to follow a
928 15. Disclaimer of Warranty.
930 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
931 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
932 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
933 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
934 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
935 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
936 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
937 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
939 16. Limitation of Liability.
941 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
942 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
943 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
944 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
945 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
946 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
947 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
948 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
951 17. Interpretation of Sections 15 and 16.
953 If the disclaimer of warranty and limitation of liability provided
954 above cannot be given local legal effect according to their terms,
955 reviewing courts shall apply local law that most closely approximates
956 an absolute waiver of all civil liability in connection with the
957 Program, unless a warranty or assumption of liability accompanies a
958 copy of the Program in return for a fee.
960 END OF TERMS AND CONDITIONS
962 How to Apply These Terms to Your New Programs
964 If you develop a new program, and you want it to be of the greatest
965 possible use to the public, the best way to achieve this is to make it
966 free software which everyone can redistribute and change under these terms.
968 To do so, attach the following notices to the program. It is safest
969 to attach them to the start of each source file to most effectively
970 state the exclusion of warranty; and each file should have at least
971 the "copyright" line and a pointer to where the full notice is found.
973 <one line to give the program's name and a brief idea of what it does.>
974 Copyright (C) <year> <name of author>
976 This program is free software: you can redistribute it and/or modify
977 it under the terms of the GNU General Public License as published by
978 the Free Software Foundation, either version 3 of the License, or
979 (at your option) any later version.
981 This program is distributed in the hope that it will be useful,
982 but WITHOUT ANY WARRANTY; without even the implied warranty of
983 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
984 GNU General Public License for more details.
986 You should have received a copy of the GNU General Public License
987 along with this program. If not, see <http://www.gnu.org/licenses/>.
989 Also add information on how to contact you by electronic and paper mail.
991 If the program does terminal interaction, make it output a short
992 notice like this when it starts in an interactive mode:
994 <program> Copyright (C) <year> <name of author>
995 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
996 This is free software, and you are welcome to redistribute it
997 under certain conditions; type `show c' for details.
999 The hypothetical commands `show w' and `show c' should show the appropriate
1000 parts of the General Public License. Of course, your program's commands
1001 might be different; for a GUI interface, you would use an "about box".
1003 You should also get your employer (if you work as a programmer) or school,
1004 if any, to sign a "copyright disclaimer" for the program, if necessary.
1005 For more information on this, and how to apply and follow the GNU GPL, see
1006 <http://www.gnu.org/licenses/>.
1008 The GNU General Public License does not permit incorporating your program
1009 into proprietary programs. If your program is a subroutine library, you
1010 may consider it more useful to permit linking proprietary applications with
1011 the library. If this is what you want to do, use the GNU Lesser General
1012 Public License instead of this License. But first, please read
1013 <http://www.gnu.org/philosophy/why-not-lgpl.html>.
1014 GNU LESSER GENERAL PUBLIC LICENSE
1015 Version 2.1, February 1999
1017 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
1018 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
1019 Everyone is permitted to copy and distribute verbatim copies
1020 of this license document, but changing it is not allowed.
1022 [This is the first released version of the Lesser GPL. It also counts
1023 as the successor of the GNU Library Public License, version 2, hence
1024 the version number 2.1.]
1028 The licenses for most software are designed to take away your
1029 freedom to share and change it. By contrast, the GNU General Public
1030 Licenses are intended to guarantee your freedom to share and change
1031 free software--to make sure the software is free for all its users.
1033 This license, the Lesser General Public License, applies to some
1034 specially designated software packages--typically libraries--of the
1035 Free Software Foundation and other authors who decide to use it. You
1036 can use it too, but we suggest you first think carefully about whether
1037 this license or the ordinary General Public License is the better
1038 strategy to use in any particular case, based on the explanations below.
1040 When we speak of free software, we are referring to freedom of use,
1041 not price. Our General Public Licenses are designed to make sure that
1042 you have the freedom to distribute copies of free software (and charge
1043 for this service if you wish); that you receive source code or can get
1044 it if you want it; that you can change the software and use pieces of
1045 it in new free programs; and that you are informed that you can do
1048 To protect your rights, we need to make restrictions that forbid
1049 distributors to deny you these rights or to ask you to surrender these
1050 rights. These restrictions translate to certain responsibilities for
1051 you if you distribute copies of the library or if you modify it.
1053 For example, if you distribute copies of the library, whether gratis
1054 or for a fee, you must give the recipients all the rights that we gave
1055 you. You must make sure that they, too, receive or can get the source
1056 code. If you link other code with the library, you must provide
1057 complete object files to the recipients, so that they can relink them
1058 with the library after making changes to the library and recompiling
1059 it. And you must show them these terms so they know their rights.
1061 We protect your rights with a two-step method: (1) we copyright the
1062 library, and (2) we offer you this license, which gives you legal
1063 permission to copy, distribute and/or modify the library.
1065 To protect each distributor, we want to make it very clear that
1066 there is no warranty for the free library. Also, if the library is
1067 modified by someone else and passed on, the recipients should know
1068 that what they have is not the original version, so that the original
1069 author's reputation will not be affected by problems that might be
1070 introduced by others.
1072 Finally, software patents pose a constant threat to the existence of
1073 any free program. We wish to make sure that a company cannot
1074 effectively restrict the users of a free program by obtaining a
1075 restrictive license from a patent holder. Therefore, we insist that
1076 any patent license obtained for a version of the library must be
1077 consistent with the full freedom of use specified in this license.
1079 Most GNU software, including some libraries, is covered by the
1080 ordinary GNU General Public License. This license, the GNU Lesser
1081 General Public License, applies to certain designated libraries, and
1082 is quite different from the ordinary General Public License. We use
1083 this license for certain libraries in order to permit linking those
1084 libraries into non-free programs.
1086 When a program is linked with a library, whether statically or using
1087 a shared library, the combination of the two is legally speaking a
1088 combined work, a derivative of the original library. The ordinary
1089 General Public License therefore permits such linking only if the
1090 entire combination fits its criteria of freedom. The Lesser General
1091 Public License permits more lax criteria for linking other code with
1094 We call this license the "Lesser" General Public License because it
1095 does Less to protect the user's freedom than the ordinary General
1096 Public License. It also provides other free software developers Less
1097 of an advantage over competing non-free programs. These disadvantages
1098 are the reason we use the ordinary General Public License for many
1099 libraries. However, the Lesser license provides advantages in certain
1100 special circumstances.
1102 For example, on rare occasions, there may be a special need to
1103 encourage the widest possible use of a certain library, so that it becomes
1104 a de-facto standard. To achieve this, non-free programs must be
1105 allowed to use the library. A more frequent case is that a free
1106 library does the same job as widely used non-free libraries. In this
1107 case, there is little to gain by limiting the free library to free
1108 software only, so we use the Lesser General Public License.
1110 In other cases, permission to use a particular library in non-free
1111 programs enables a greater number of people to use a large body of
1112 free software. For example, permission to use the GNU C Library in
1113 non-free programs enables many more people to use the whole GNU
1114 operating system, as well as its variant, the GNU/Linux operating
1117 Although the Lesser General Public License is Less protective of the
1118 users' freedom, it does ensure that the user of a program that is
1119 linked with the Library has the freedom and the wherewithal to run
1120 that program using a modified version of the Library.
1122 The precise terms and conditions for copying, distribution and
1123 modification follow. Pay close attention to the difference between a
1124 "work based on the library" and a "work that uses the library". The
1125 former contains code derived from the library, whereas the latter must
1126 be combined with the library in order to run.
1128 GNU LESSER GENERAL PUBLIC LICENSE
1129 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
1131 0. This License Agreement applies to any software library or other
1132 program which contains a notice placed by the copyright holder or
1133 other authorized party saying it may be distributed under the terms of
1134 this Lesser General Public License (also called "this License").
1135 Each licensee is addressed as "you".
1137 A "library" means a collection of software functions and/or data
1138 prepared so as to be conveniently linked with application programs
1139 (which use some of those functions and data) to form executables.
1141 The "Library", below, refers to any such software library or work
1142 which has been distributed under these terms. A "work based on the
1143 Library" means either the Library or any derivative work under
1144 copyright law: that is to say, a work containing the Library or a
1145 portion of it, either verbatim or with modifications and/or translated
1146 straightforwardly into another language. (Hereinafter, translation is
1147 included without limitation in the term "modification".)
1149 "Source code" for a work means the preferred form of the work for
1150 making modifications to it. For a library, complete source code means
1151 all the source code for all modules it contains, plus any associated
1152 interface definition files, plus the scripts used to control compilation
1153 and installation of the library.
1155 Activities other than copying, distribution and modification are not
1156 covered by this License; they are outside its scope. The act of
1157 running a program using the Library is not restricted, and output from
1158 such a program is covered only if its contents constitute a work based
1159 on the Library (independent of the use of the Library in a tool for
1160 writing it). Whether that is true depends on what the Library does
1161 and what the program that uses the Library does.
1163 1. You may copy and distribute verbatim copies of the Library's
1164 complete source code as you receive it, in any medium, provided that
1165 you conspicuously and appropriately publish on each copy an
1166 appropriate copyright notice and disclaimer of warranty; keep intact
1167 all the notices that refer to this License and to the absence of any
1168 warranty; and distribute a copy of this License along with the
1171 You may charge a fee for the physical act of transferring a copy,
1172 and you may at your option offer warranty protection in exchange for a
1175 2. You may modify your copy or copies of the Library or any portion
1176 of it, thus forming a work based on the Library, and copy and
1177 distribute such modifications or work under the terms of Section 1
1178 above, provided that you also meet all of these conditions:
1180 a) The modified work must itself be a software library.
1182 b) You must cause the files modified to carry prominent notices
1183 stating that you changed the files and the date of any change.
1185 c) You must cause the whole of the work to be licensed at no
1186 charge to all third parties under the terms of this License.
1188 d) If a facility in the modified Library refers to a function or a
1189 table of data to be supplied by an application program that uses
1190 the facility, other than as an argument passed when the facility
1191 is invoked, then you must make a good faith effort to ensure that,
1192 in the event an application does not supply such function or
1193 table, the facility still operates, and performs whatever part of
1194 its purpose remains meaningful.
1196 (For example, a function in a library to compute square roots has
1197 a purpose that is entirely well-defined independent of the
1198 application. Therefore, Subsection 2d requires that any
1199 application-supplied function or table used by this function must
1200 be optional: if the application does not supply it, the square
1201 root function must still compute square roots.)
1203 These requirements apply to the modified work as a whole. If
1204 identifiable sections of that work are not derived from the Library,
1205 and can be reasonably considered independent and separate works in
1206 themselves, then this License, and its terms, do not apply to those
1207 sections when you distribute them as separate works. But when you
1208 distribute the same sections as part of a whole which is a work based
1209 on the Library, the distribution of the whole must be on the terms of
1210 this License, whose permissions for other licensees extend to the
1211 entire whole, and thus to each and every part regardless of who wrote
1214 Thus, it is not the intent of this section to claim rights or contest
1215 your rights to work written entirely by you; rather, the intent is to
1216 exercise the right to control the distribution of derivative or
1217 collective works based on the Library.
1219 In addition, mere aggregation of another work not based on the Library
1220 with the Library (or with a work based on the Library) on a volume of
1221 a storage or distribution medium does not bring the other work under
1222 the scope of this License.
1224 3. You may opt to apply the terms of the ordinary GNU General Public
1225 License instead of this License to a given copy of the Library. To do
1226 this, you must alter all the notices that refer to this License, so
1227 that they refer to the ordinary GNU General Public License, version 2,
1228 instead of to this License. (If a newer version than version 2 of the
1229 ordinary GNU General Public License has appeared, then you can specify
1230 that version instead if you wish.) Do not make any other change in
1233 Once this change is made in a given copy, it is irreversible for
1234 that copy, so the ordinary GNU General Public License applies to all
1235 subsequent copies and derivative works made from that copy.
1237 This option is useful when you wish to copy part of the code of
1238 the Library into a program that is not a library.
1240 4. You may copy and distribute the Library (or a portion or
1241 derivative of it, under Section 2) in object code or executable form
1242 under the terms of Sections 1 and 2 above provided that you accompany
1243 it with the complete corresponding machine-readable source code, which
1244 must be distributed under the terms of Sections 1 and 2 above on a
1245 medium customarily used for software interchange.
1247 If distribution of object code is made by offering access to copy
1248 from a designated place, then offering equivalent access to copy the
1249 source code from the same place satisfies the requirement to
1250 distribute the source code, even though third parties are not
1251 compelled to copy the source along with the object code.
1253 5. A program that contains no derivative of any portion of the
1254 Library, but is designed to work with the Library by being compiled or
1255 linked with it, is called a "work that uses the Library". Such a
1256 work, in isolation, is not a derivative work of the Library, and
1257 therefore falls outside the scope of this License.
1259 However, linking a "work that uses the Library" with the Library
1260 creates an executable that is a derivative of the Library (because it
1261 contains portions of the Library), rather than a "work that uses the
1262 library". The executable is therefore covered by this License.
1263 Section 6 states terms for distribution of such executables.
1265 When a "work that uses the Library" uses material from a header file
1266 that is part of the Library, the object code for the work may be a
1267 derivative work of the Library even though the source code is not.
1268 Whether this is true is especially significant if the work can be
1269 linked without the Library, or if the work is itself a library. The
1270 threshold for this to be true is not precisely defined by law.
1272 If such an object file uses only numerical parameters, data
1273 structure layouts and accessors, and small macros and small inline
1274 functions (ten lines or less in length), then the use of the object
1275 file is unrestricted, regardless of whether it is legally a derivative
1276 work. (Executables containing this object code plus portions of the
1277 Library will still fall under Section 6.)
1279 Otherwise, if the work is a derivative of the Library, you may
1280 distribute the object code for the work under the terms of Section 6.
1281 Any executables containing that work also fall under Section 6,
1282 whether or not they are linked directly with the Library itself.
1284 6. As an exception to the Sections above, you may also combine or
1285 link a "work that uses the Library" with the Library to produce a
1286 work containing portions of the Library, and distribute that work
1287 under terms of your choice, provided that the terms permit
1288 modification of the work for the customer's own use and reverse
1289 engineering for debugging such modifications.
1291 You must give prominent notice with each copy of the work that the
1292 Library is used in it and that the Library and its use are covered by
1293 this License. You must supply a copy of this License. If the work
1294 during execution displays copyright notices, you must include the
1295 copyright notice for the Library among them, as well as a reference
1296 directing the user to the copy of this License. Also, you must do one
1299 a) Accompany the work with the complete corresponding
1300 machine-readable source code for the Library including whatever
1301 changes were used in the work (which must be distributed under
1302 Sections 1 and 2 above); and, if the work is an executable linked
1303 with the Library, with the complete machine-readable "work that
1304 uses the Library", as object code and/or source code, so that the
1305 user can modify the Library and then relink to produce a modified
1306 executable containing the modified Library. (It is understood
1307 that the user who changes the contents of definitions files in the
1308 Library will not necessarily be able to recompile the application
1309 to use the modified definitions.)
1311 b) Use a suitable shared library mechanism for linking with the
1312 Library. A suitable mechanism is one that (1) uses at run time a
1313 copy of the library already present on the user's computer system,
1314 rather than copying library functions into the executable, and (2)
1315 will operate properly with a modified version of the library, if
1316 the user installs one, as long as the modified version is
1317 interface-compatible with the version that the work was made with.
1319 c) Accompany the work with a written offer, valid for at
1320 least three years, to give the same user the materials
1321 specified in Subsection 6a, above, for a charge no more
1322 than the cost of performing this distribution.
1324 d) If distribution of the work is made by offering access to copy
1325 from a designated place, offer equivalent access to copy the above
1326 specified materials from the same place.
1328 e) Verify that the user has already received a copy of these
1329 materials or that you have already sent this user a copy.
1331 For an executable, the required form of the "work that uses the
1332 Library" must include any data and utility programs needed for
1333 reproducing the executable from it. However, as a special exception,
1334 the materials to be distributed need not include anything that is
1335 normally distributed (in either source or binary form) with the major
1336 components (compiler, kernel, and so on) of the operating system on
1337 which the executable runs, unless that component itself accompanies
1340 It may happen that this requirement contradicts the license
1341 restrictions of other proprietary libraries that do not normally
1342 accompany the operating system. Such a contradiction means you cannot
1343 use both them and the Library together in an executable that you
1346 7. You may place library facilities that are a work based on the
1347 Library side-by-side in a single library together with other library
1348 facilities not covered by this License, and distribute such a combined
1349 library, provided that the separate distribution of the work based on
1350 the Library and of the other library facilities is otherwise
1351 permitted, and provided that you do these two things:
1353 a) Accompany the combined library with a copy of the same work
1354 based on the Library, uncombined with any other library
1355 facilities. This must be distributed under the terms of the
1358 b) Give prominent notice with the combined library of the fact
1359 that part of it is a work based on the Library, and explaining
1360 where to find the accompanying uncombined form of the same work.
1362 8. You may not copy, modify, sublicense, link with, or distribute
1363 the Library except as expressly provided under this License. Any
1364 attempt otherwise to copy, modify, sublicense, link with, or
1365 distribute the Library is void, and will automatically terminate your
1366 rights under this License. However, parties who have received copies,
1367 or rights, from you under this License will not have their licenses
1368 terminated so long as such parties remain in full compliance.
1370 9. You are not required to accept this License, since you have not
1371 signed it. However, nothing else grants you permission to modify or
1372 distribute the Library or its derivative works. These actions are
1373 prohibited by law if you do not accept this License. Therefore, by
1374 modifying or distributing the Library (or any work based on the
1375 Library), you indicate your acceptance of this License to do so, and
1376 all its terms and conditions for copying, distributing or modifying
1377 the Library or works based on it.
1379 10. Each time you redistribute the Library (or any work based on the
1380 Library), the recipient automatically receives a license from the
1381 original licensor to copy, distribute, link with or modify the Library
1382 subject to these terms and conditions. You may not impose any further
1383 restrictions on the recipients' exercise of the rights granted herein.
1384 You are not responsible for enforcing compliance by third parties with
1387 11. If, as a consequence of a court judgment or allegation of patent
1388 infringement or for any other reason (not limited to patent issues),
1389 conditions are imposed on you (whether by court order, agreement or
1390 otherwise) that contradict the conditions of this License, they do not
1391 excuse you from the conditions of this License. If you cannot
1392 distribute so as to satisfy simultaneously your obligations under this
1393 License and any other pertinent obligations, then as a consequence you
1394 may not distribute the Library at all. For example, if a patent
1395 license would not permit royalty-free redistribution of the Library by
1396 all those who receive copies directly or indirectly through you, then
1397 the only way you could satisfy both it and this License would be to
1398 refrain entirely from distribution of the Library.
1400 If any portion of this section is held invalid or unenforceable under any
1401 particular circumstance, the balance of the section is intended to apply,
1402 and the section as a whole is intended to apply in other circumstances.
1404 It is not the purpose of this section to induce you to infringe any
1405 patents or other property right claims or to contest validity of any
1406 such claims; this section has the sole purpose of protecting the
1407 integrity of the free software distribution system which is
1408 implemented by public license practices. Many people have made
1409 generous contributions to the wide range of software distributed
1410 through that system in reliance on consistent application of that
1411 system; it is up to the author/donor to decide if he or she is willing
1412 to distribute software through any other system and a licensee cannot
1415 This section is intended to make thoroughly clear what is believed to
1416 be a consequence of the rest of this License.
1418 12. If the distribution and/or use of the Library is restricted in
1419 certain countries either by patents or by copyrighted interfaces, the
1420 original copyright holder who places the Library under this License may add
1421 an explicit geographical distribution limitation excluding those countries,
1422 so that distribution is permitted only in or among countries not thus
1423 excluded. In such case, this License incorporates the limitation as if
1424 written in the body of this License.
1426 13. The Free Software Foundation may publish revised and/or new
1427 versions of the Lesser General Public License from time to time.
1428 Such new versions will be similar in spirit to the present version,
1429 but may differ in detail to address new problems or concerns.
1431 Each version is given a distinguishing version number. If the Library
1432 specifies a version number of this License which applies to it and
1433 "any later version", you have the option of following the terms and
1434 conditions either of that version or of any later version published by
1435 the Free Software Foundation. If the Library does not specify a
1436 license version number, you may choose any version ever published by
1437 the Free Software Foundation.
1439 14. If you wish to incorporate parts of the Library into other free
1440 programs whose distribution conditions are incompatible with these,
1441 write to the author to ask for permission. For software which is
1442 copyrighted by the Free Software Foundation, write to the Free
1443 Software Foundation; we sometimes make exceptions for this. Our
1444 decision will be guided by the two goals of preserving the free status
1445 of all derivatives of our free software and of promoting the sharing
1446 and reuse of software generally.
1450 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
1451 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
1452 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
1453 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
1454 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
1455 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
1456 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
1457 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
1458 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
1460 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
1461 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
1462 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
1463 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
1464 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
1465 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
1466 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
1467 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
1468 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
1471 END OF TERMS AND CONDITIONS
1473 How to Apply These Terms to Your New Libraries
1475 If you develop a new library, and you want it to be of the greatest
1476 possible use to the public, we recommend making it free software that
1477 everyone can redistribute and change. You can do so by permitting
1478 redistribution under these terms (or, alternatively, under the terms of the
1479 ordinary General Public License).
1481 To apply these terms, attach the following notices to the library. It is
1482 safest to attach them to the start of each source file to most effectively
1483 convey the exclusion of warranty; and each file should have at least the
1484 "copyright" line and a pointer to where the full notice is found.
1486 <one line to give the library's name and a brief idea of what it does.>
1487 Copyright (C) <year> <name of author>
1489 This library is free software; you can redistribute it and/or
1490 modify it under the terms of the GNU Lesser General Public
1491 License as published by the Free Software Foundation; either

1494 This library is distributed in the hope that it will be useful,
1495 but WITHOUT ANY WARRANTY; without even the implied warranty of

1507 necessary. Here is a sample; alter the names:
