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 Library 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
307 along with this program; if not, write to the Free Software
308 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
311 Also add information on how to contact you by electronic and paper mail.
313 If the program is interactive, make it output a short notice like this
314 when it starts in an interactive mode:
316 Gnomovision version 69, Copyright (C) year name of author
317 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
318 This is free software, and you are welcome to redistribute it
319 under certain conditions; type `show c' for details.
321 The hypothetical commands `show w' and `show c' should show the appropriate
322 parts of the General Public License. Of course, the commands you use may
323 be called something other than `show w' and `show c'; they could even be
324 mouse-clicks or menu items--whatever suits your program.
326 You should also get your employer (if you work as a programmer) or your
327 school, if any, to sign a "copyright disclaimer" for the program, if
328 necessary. Here is a sample; alter the names:
330 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
331 `Gnomovision' (which makes passes at compilers) written by James Hacker.
333 <signature of Ty Coon>, 1 April 1989
334 Ty Coon, President of Vice
336 This General Public License does not permit incorporating your program into
337 proprietary programs. If your program is a subroutine library, you may
338 consider it more useful to permit linking proprietary applications with the
339 library. If this is what you want to do, use the GNU Library General
340 Public License instead of this License.
341 ===========================================================================
342 GNU LESSER GENERAL PUBLIC LICENSE
343 Version 2.1, February 1999
345 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
346 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
347 Everyone is permitted to copy and distribute verbatim copies
348 of this license document, but changing it is not allowed.
350 [This is the first released version of the Lesser GPL. It also counts
351 as the successor of the GNU Library Public License, version 2, hence
352 the version number 2.1.]
356 The licenses for most software are designed to take away your
357 freedom to share and change it. By contrast, the GNU General Public
358 Licenses are intended to guarantee your freedom to share and change
359 free software--to make sure the software is free for all its users.
361 This license, the Lesser General Public License, applies to some
362 specially designated software packages--typically libraries--of the
363 Free Software Foundation and other authors who decide to use it. You
364 can use it too, but we suggest you first think carefully about whether
365 this license or the ordinary General Public License is the better
366 strategy to use in any particular case, based on the explanations below.
368 When we speak of free software, we are referring to freedom of use,
369 not price. Our General Public Licenses are designed to make sure that
370 you have the freedom to distribute copies of free software (and charge
371 for this service if you wish); that you receive source code or can get
372 it if you want it; that you can change the software and use pieces of
373 it in new free programs; and that you are informed that you can do
376 To protect your rights, we need to make restrictions that forbid
377 distributors to deny you these rights or to ask you to surrender these
378 rights. These restrictions translate to certain responsibilities for
379 you if you distribute copies of the library or if you modify it.
381 For example, if you distribute copies of the library, whether gratis
382 or for a fee, you must give the recipients all the rights that we gave
383 you. You must make sure that they, too, receive or can get the source
384 code. If you link other code with the library, you must provide
385 complete object files to the recipients, so that they can relink them
386 with the library after making changes to the library and recompiling
387 it. And you must show them these terms so they know their rights.
389 We protect your rights with a two-step method: (1) we copyright the
390 library, and (2) we offer you this license, which gives you legal
391 permission to copy, distribute and/or modify the library.
393 To protect each distributor, we want to make it very clear that
394 there is no warranty for the free library. Also, if the library is
395 modified by someone else and passed on, the recipients should know
396 that what they have is not the original version, so that the original
397 author's reputation will not be affected by problems that might be
398 introduced by others.
400 Finally, software patents pose a constant threat to the existence of
401 any free program. We wish to make sure that a company cannot
402 effectively restrict the users of a free program by obtaining a
403 restrictive license from a patent holder. Therefore, we insist that
404 any patent license obtained for a version of the library must be
405 consistent with the full freedom of use specified in this license.
407 Most GNU software, including some libraries, is covered by the
408 ordinary GNU General Public License. This license, the GNU Lesser
409 General Public License, applies to certain designated libraries, and
410 is quite different from the ordinary General Public License. We use
411 this license for certain libraries in order to permit linking those
412 libraries into non-free programs.
414 When a program is linked with a library, whether statically or using
415 a shared library, the combination of the two is legally speaking a
416 combined work, a derivative of the original library. The ordinary
417 General Public License therefore permits such linking only if the
418 entire combination fits its criteria of freedom. The Lesser General
419 Public License permits more lax criteria for linking other code with
422 We call this license the "Lesser" General Public License because it
423 does Less to protect the user's freedom than the ordinary General
424 Public License. It also provides other free software developers Less
425 of an advantage over competing non-free programs. These disadvantages
426 are the reason we use the ordinary General Public License for many
427 libraries. However, the Lesser license provides advantages in certain
428 special circumstances.
430 For example, on rare occasions, there may be a special need to
431 encourage the widest possible use of a certain library, so that it becomes
432 a de-facto standard. To achieve this, non-free programs must be
433 allowed to use the library. A more frequent case is that a free
434 library does the same job as widely used non-free libraries. In this
435 case, there is little to gain by limiting the free library to free
436 software only, so we use the Lesser General Public License.
438 In other cases, permission to use a particular library in non-free
439 programs enables a greater number of people to use a large body of
440 free software. For example, permission to use the GNU C Library in
441 non-free programs enables many more people to use the whole GNU
442 operating system, as well as its variant, the GNU/Linux operating
445 Although the Lesser General Public License is Less protective of the
446 users' freedom, it does ensure that the user of a program that is
447 linked with the Library has the freedom and the wherewithal to run
448 that program using a modified version of the Library.
450 The precise terms and conditions for copying, distribution and
451 modification follow. Pay close attention to the difference between a
452 "work based on the library" and a "work that uses the library". The
453 former contains code derived from the library, whereas the latter must
454 be combined with the library in order to run.
456 GNU LESSER GENERAL PUBLIC LICENSE
457 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
459 0. This License Agreement applies to any software library or other
460 program which contains a notice placed by the copyright holder or
461 other authorized party saying it may be distributed under the terms of
462 this Lesser General Public License (also called "this License").
463 Each licensee is addressed as "you".
465 A "library" means a collection of software functions and/or data
466 prepared so as to be conveniently linked with application programs
467 (which use some of those functions and data) to form executables.
469 The "Library", below, refers to any such software library or work
470 which has been distributed under these terms. A "work based on the
471 Library" means either the Library or any derivative work under
472 copyright law: that is to say, a work containing the Library or a
473 portion of it, either verbatim or with modifications and/or translated
474 straightforwardly into another language. (Hereinafter, translation is
475 included without limitation in the term "modification".)
477 "Source code" for a work means the preferred form of the work for
478 making modifications to it. For a library, complete source code means
479 all the source code for all modules it contains, plus any associated
480 interface definition files, plus the scripts used to control compilation
481 and installation of the library.
483 Activities other than copying, distribution and modification are not
484 covered by this License; they are outside its scope. The act of
485 running a program using the Library is not restricted, and output from
486 such a program is covered only if its contents constitute a work based
487 on the Library (independent of the use of the Library in a tool for
488 writing it). Whether that is true depends on what the Library does
489 and what the program that uses the Library does.
491 1. You may copy and distribute verbatim copies of the Library's
492 complete source code as you receive it, in any medium, provided that
493 you conspicuously and appropriately publish on each copy an
494 appropriate copyright notice and disclaimer of warranty; keep intact
495 all the notices that refer to this License and to the absence of any
496 warranty; and distribute a copy of this License along with the
499 You may charge a fee for the physical act of transferring a copy,
500 and you may at your option offer warranty protection in exchange for a
503 2. You may modify your copy or copies of the Library or any portion
504 of it, thus forming a work based on the Library, and copy and
505 distribute such modifications or work under the terms of Section 1
506 above, provided that you also meet all of these conditions:
508 a) The modified work must itself be a software library.
510 b) You must cause the files modified to carry prominent notices
511 stating that you changed the files and the date of any change.
513 c) You must cause the whole of the work to be licensed at no
514 charge to all third parties under the terms of this License.
516 d) If a facility in the modified Library refers to a function or a
517 table of data to be supplied by an application program that uses
518 the facility, other than as an argument passed when the facility
519 is invoked, then you must make a good faith effort to ensure that,
520 in the event an application does not supply such function or
521 table, the facility still operates, and performs whatever part of
522 its purpose remains meaningful.
524 (For example, a function in a library to compute square roots has
525 a purpose that is entirely well-defined independent of the
526 application. Therefore, Subsection 2d requires that any
527 application-supplied function or table used by this function must
528 be optional: if the application does not supply it, the square
529 root function must still compute square roots.)
531 These requirements apply to the modified work as a whole. If
532 identifiable sections of that work are not derived from the Library,
533 and can be reasonably considered independent and separate works in
534 themselves, then this License, and its terms, do not apply to those
535 sections when you distribute them as separate works. But when you
536 distribute the same sections as part of a whole which is a work based
537 on the Library, the distribution of the whole must be on the terms of
538 this License, whose permissions for other licensees extend to the
539 entire whole, and thus to each and every part regardless of who wrote
542 Thus, it is not the intent of this section to claim rights or contest
543 your rights to work written entirely by you; rather, the intent is to
544 exercise the right to control the distribution of derivative or
545 collective works based on the Library.
547 In addition, mere aggregation of another work not based on the Library
548 with the Library (or with a work based on the Library) on a volume of
549 a storage or distribution medium does not bring the other work under
550 the scope of this License.
552 3. You may opt to apply the terms of the ordinary GNU General Public
553 License instead of this License to a given copy of the Library. To do
554 this, you must alter all the notices that refer to this License, so
555 that they refer to the ordinary GNU General Public License, version 2,
556 instead of to this License. (If a newer version than version 2 of the
557 ordinary GNU General Public License has appeared, then you can specify
558 that version instead if you wish.) Do not make any other change in
561 Once this change is made in a given copy, it is irreversible for
562 that copy, so the ordinary GNU General Public License applies to all
563 subsequent copies and derivative works made from that copy.
565 This option is useful when you wish to copy part of the code of
566 the Library into a program that is not a library.
568 4. You may copy and distribute the Library (or a portion or
569 derivative of it, under Section 2) in object code or executable form
570 under the terms of Sections 1 and 2 above provided that you accompany
571 it with the complete corresponding machine-readable source code, which
572 must be distributed under the terms of Sections 1 and 2 above on a
573 medium customarily used for software interchange.
575 If distribution of object code is made by offering access to copy
576 from a designated place, then offering equivalent access to copy the
577 source code from the same place satisfies the requirement to
578 distribute the source code, even though third parties are not
579 compelled to copy the source along with the object code.
581 5. A program that contains no derivative of any portion of the
582 Library, but is designed to work with the Library by being compiled or
583 linked with it, is called a "work that uses the Library". Such a
584 work, in isolation, is not a derivative work of the Library, and
585 therefore falls outside the scope of this License.
587 However, linking a "work that uses the Library" with the Library
588 creates an executable that is a derivative of the Library (because it
589 contains portions of the Library), rather than a "work that uses the
590 library". The executable is therefore covered by this License.
591 Section 6 states terms for distribution of such executables.
593 When a "work that uses the Library" uses material from a header file
594 that is part of the Library, the object code for the work may be a
595 derivative work of the Library even though the source code is not.
596 Whether this is true is especially significant if the work can be
597 linked without the Library, or if the work is itself a library. The
598 threshold for this to be true is not precisely defined by law.
600 If such an object file uses only numerical parameters, data
601 structure layouts and accessors, and small macros and small inline
602 functions (ten lines or less in length), then the use of the object
603 file is unrestricted, regardless of whether it is legally a derivative
604 work. (Executables containing this object code plus portions of the
605 Library will still fall under Section 6.)
607 Otherwise, if the work is a derivative of the Library, you may
608 distribute the object code for the work under the terms of Section 6.
609 Any executables containing that work also fall under Section 6,
610 whether or not they are linked directly with the Library itself.
612 6. As an exception to the Sections above, you may also combine or
613 link a "work that uses the Library" with the Library to produce a
614 work containing portions of the Library, and distribute that work
615 under terms of your choice, provided that the terms permit
616 modification of the work for the customer's own use and reverse
617 engineering for debugging such modifications.
619 You must give prominent notice with each copy of the work that the
620 Library is used in it and that the Library and its use are covered by
621 this License. You must supply a copy of this License. If the work
622 during execution displays copyright notices, you must include the
623 copyright notice for the Library among them, as well as a reference
624 directing the user to the copy of this License. Also, you must do one
627 a) Accompany the work with the complete corresponding
628 machine-readable source code for the Library including whatever
629 changes were used in the work (which must be distributed under
630 Sections 1 and 2 above); and, if the work is an executable linked
631 with the Library, with the complete machine-readable "work that
632 uses the Library", as object code and/or source code, so that the
633 user can modify the Library and then relink to produce a modified
634 executable containing the modified Library. (It is understood
635 that the user who changes the contents of definitions files in the
636 Library will not necessarily be able to recompile the application
637 to use the modified definitions.)
639 b) Use a suitable shared library mechanism for linking with the
640 Library. A suitable mechanism is one that (1) uses at run time a
641 copy of the library already present on the user's computer system,
642 rather than copying library functions into the executable, and (2)
643 will operate properly with a modified version of the library, if
644 the user installs one, as long as the modified version is
645 interface-compatible with the version that the work was made with.
647 c) Accompany the work with a written offer, valid for at
648 least three years, to give the same user the materials
649 specified in Subsection 6a, above, for a charge no more
650 than the cost of performing this distribution.
652 d) If distribution of the work is made by offering access to copy
653 from a designated place, offer equivalent access to copy the above
654 specified materials from the same place.
656 e) Verify that the user has already received a copy of these
657 materials or that you have already sent this user a copy.
659 For an executable, the required form of the "work that uses the
660 Library" must include any data and utility programs needed for
661 reproducing the executable from it. However, as a special exception,
662 the materials to be distributed need not include anything that is
663 normally distributed (in either source or binary form) with the major
664 components (compiler, kernel, and so on) of the operating system on
665 which the executable runs, unless that component itself accompanies
668 It may happen that this requirement contradicts the license
669 restrictions of other proprietary libraries that do not normally
670 accompany the operating system. Such a contradiction means you cannot
671 use both them and the Library together in an executable that you
674 7. You may place library facilities that are a work based on the
675 Library side-by-side in a single library together with other library
676 facilities not covered by this License, and distribute such a combined
677 library, provided that the separate distribution of the work based on
678 the Library and of the other library facilities is otherwise
679 permitted, and provided that you do these two things:
681 a) Accompany the combined library with a copy of the same work
682 based on the Library, uncombined with any other library
683 facilities. This must be distributed under the terms of the
686 b) Give prominent notice with the combined library of the fact
687 that part of it is a work based on the Library, and explaining
688 where to find the accompanying uncombined form of the same work.
690 8. You may not copy, modify, sublicense, link with, or distribute
691 the Library except as expressly provided under this License. Any
692 attempt otherwise to copy, modify, sublicense, link with, or
693 distribute the Library is void, and will automatically terminate your
694 rights under this License. However, parties who have received copies,
695 or rights, from you under this License will not have their licenses
696 terminated so long as such parties remain in full compliance.
698 9. You are not required to accept this License, since you have not
699 signed it. However, nothing else grants you permission to modify or
700 distribute the Library or its derivative works. These actions are
701 prohibited by law if you do not accept this License. Therefore, by
702 modifying or distributing the Library (or any work based on the
703 Library), you indicate your acceptance of this License to do so, and
704 all its terms and conditions for copying, distributing or modifying
705 the Library or works based on it.
707 10. Each time you redistribute the Library (or any work based on the
708 Library), the recipient automatically receives a license from the
709 original licensor to copy, distribute, link with or modify the Library
710 subject to these terms and conditions. You may not impose any further
711 restrictions on the recipients' exercise of the rights granted herein.
712 You are not responsible for enforcing compliance by third parties with
715 11. If, as a consequence of a court judgment or allegation of patent
716 infringement or for any other reason (not limited to patent issues),
717 conditions are imposed on you (whether by court order, agreement or
718 otherwise) that contradict the conditions of this License, they do not
719 excuse you from the conditions of this License. If you cannot
720 distribute so as to satisfy simultaneously your obligations under this
721 License and any other pertinent obligations, then as a consequence you
722 may not distribute the Library at all. For example, if a patent
723 license would not permit royalty-free redistribution of the Library by
724 all those who receive copies directly or indirectly through you, then
725 the only way you could satisfy both it and this License would be to
726 refrain entirely from distribution of the Library.
728 If any portion of this section is held invalid or unenforceable under any
729 particular circumstance, the balance of the section is intended to apply,
730 and the section as a whole is intended to apply in other circumstances.
732 It is not the purpose of this section to induce you to infringe any
733 patents or other property right claims or to contest validity of any
734 such claims; this section has the sole purpose of protecting the
735 integrity of the free software distribution system which is
736 implemented by public license practices. Many people have made
737 generous contributions to the wide range of software distributed
738 through that system in reliance on consistent application of that
739 system; it is up to the author/donor to decide if he or she is willing
740 to distribute software through any other system and a licensee cannot
743 This section is intended to make thoroughly clear what is believed to
744 be a consequence of the rest of this License.
746 12. If the distribution and/or use of the Library is restricted in
747 certain countries either by patents or by copyrighted interfaces, the
748 original copyright holder who places the Library under this License may add
749 an explicit geographical distribution limitation excluding those countries,
750 so that distribution is permitted only in or among countries not thus
751 excluded. In such case, this License incorporates the limitation as if
752 written in the body of this License.
754 13. The Free Software Foundation may publish revised and/or new
755 versions of the Lesser General Public License from time to time.
756 Such new versions will be similar in spirit to the present version,
757 but may differ in detail to address new problems or concerns.
759 Each version is given a distinguishing version number. If the Library
760 specifies a version number of this License which applies to it and
761 "any later version", you have the option of following the terms and
762 conditions either of that version or of any later version published by
763 the Free Software Foundation. If the Library does not specify a
764 license version number, you may choose any version ever published by
765 the Free Software Foundation.
767 14. If you wish to incorporate parts of the Library into other free
768 programs whose distribution conditions are incompatible with these,
769 write to the author to ask for permission. For software which is
770 copyrighted by the Free Software Foundation, write to the Free
771 Software Foundation; we sometimes make exceptions for this. Our
772 decision will be guided by the two goals of preserving the free status
773 of all derivatives of our free software and of promoting the sharing
774 and reuse of software generally.
778 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
779 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
780 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
781 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
782 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
783 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
784 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
785 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
786 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
788 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
789 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
790 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
791 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
792 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
793 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
794 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
795 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
796 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
799 END OF TERMS AND CONDITIONS
801 How to Apply These Terms to Your New Libraries
803 If you develop a new library, and you want it to be of the greatest
804 possible use to the public, we recommend making it free software that
805 everyone can redistribute and change. You can do so by permitting
806 redistribution under these terms (or, alternatively, under the terms of the
807 ordinary General Public License).
809 To apply these terms, attach the following notices to the library. It is
810 safest to attach them to the start of each source file to most effectively
811 convey the exclusion of warranty; and each file should have at least the
812 "copyright" line and a pointer to where the full notice is found.
814 <one line to give the library's name and a brief idea of what it does.>
815 Copyright (C) <year> <name of author>
817 This library is free software; you can redistribute it and/or
818 modify it under the terms of the GNU Lesser General Public
819 License as published by the Free Software Foundation; either
820 version 2.1 of the License, or (at your option) any later version.
822 This library is distributed in the hope that it will be useful,
823 but WITHOUT ANY WARRANTY; without even the implied warranty of
824 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
825 Lesser General Public License for more details.
827 You should have received a copy of the GNU Lesser General Public
828 License along with this library; if not, write to the Free Software
829 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
831 Also add information on how to contact you by electronic and paper mail.
833 You should also get your employer (if you work as a programmer) or your
834 school, if any, to sign a "copyright disclaimer" for the library, if
835 necessary. Here is a sample; alter the names:
