6 Everyone is permitted to copy and distribute verbatim copies
7 of this license document, but changing it is not allowed.
9 [This is the first released version of the Lesser GPL. It also counts
10 as the successor of the GNU Library Public License, version 2, hence
11 the version number 2.1.]
15 The licenses for most software are designed to take away your
16 freedom to share and change it. By contrast, the GNU General Public
17 Licenses are intended to guarantee your freedom to share and change
18 free software--to make sure the software is free for all its users.
20 This license, the Lesser General Public License, applies to some
21 specially designated software packages--typically libraries--of the
22 Free Software Foundation and other authors who decide to use it. You
23 can use it too, but we suggest you first think carefully about whether
24 this license or the ordinary General Public License is the better
25 strategy to use in any particular case, based on the explanations
28 When we speak of free software, we are referring to freedom of use,
29 not price. Our General Public Licenses are designed to make sure that
30 you have the freedom to distribute copies of free software (and charge
31 for this service if you wish); that you receive source code or can get
32 it if you want it; that you can change the software and use pieces of
33 it in new free programs; and that you are informed that you can do
36 To protect your rights, we need to make restrictions that forbid
37 distributors to deny you these rights or to ask you to surrender these
38 rights. These restrictions translate to certain responsibilities for
39 you if you distribute copies of the library or if you modify it.
41 For example, if you distribute copies of the library, whether gratis
42 or for a fee, you must give the recipients all the rights that we gave
43 you. You must make sure that they, too, receive or can get the source
44 code. If you link other code with the library, you must provide
45 complete object files to the recipients, so that they can relink them
46 with the library after making changes to the library and recompiling
47 it. And you must show them these terms so they know their rights.
49 We protect your rights with a two-step method: (1) we copyright the
50 library, and (2) we offer you this license, which gives you legal
51 permission to copy, distribute and/or modify the library.
53 To protect each distributor, we want to make it very clear that
54 there is no warranty for the free library. Also, if the library is
55 modified by someone else and passed on, the recipients should know
56 that what they have is not the original version, so that the original
57 author's reputation will not be affected by problems that might be
60 Finally, software patents pose a constant threat to the existence of
61 any free program. We wish to make sure that a company cannot
62 effectively restrict the users of a free program by obtaining a
63 restrictive license from a patent holder. Therefore, we insist that
64 any patent license obtained for a version of the library must be
65 consistent with the full freedom of use specified in this license.
67 Most GNU software, including some libraries, is covered by the
68 ordinary GNU General Public License. This license, the GNU Lesser
69 General Public License, applies to certain designated libraries, and
70 is quite different from the ordinary General Public License. We use
71 this license for certain libraries in order to permit linking those
72 libraries into non-free programs.
74 When a program is linked with a library, whether statically or using
75 a shared library, the combination of the two is legally speaking a
76 combined work, a derivative of the original library. The ordinary
77 General Public License therefore permits such linking only if the
78 entire combination fits its criteria of freedom. The Lesser General
79 Public License permits more lax criteria for linking other code with
82 We call this license the "Lesser" General Public License because it
83 does Less to protect the user's freedom than the ordinary General
84 Public License. It also provides other free software developers Less
85 of an advantage over competing non-free programs. These disadvantages
86 are the reason we use the ordinary General Public License for many
87 libraries. However, the Lesser license provides advantages in certain
88 special circumstances.
90 For example, on rare occasions, there may be a special need to
91 encourage the widest possible use of a certain library, so that it
92 becomes a de-facto standard. To achieve this, non-free programs must
93 be allowed to use the library. A more frequent case is that a free
94 library does the same job as widely used non-free libraries. In this
95 case, there is little to gain by limiting the free library to free
96 software only, so we use the Lesser General Public License.
98 In other cases, permission to use a particular library in non-free
99 programs enables a greater number of people to use a large body of
100 free software. For example, permission to use the GNU C Library in
101 non-free programs enables many more people to use the whole GNU
102 operating system, as well as its variant, the GNU/Linux operating
105 Although the Lesser General Public License is Less protective of the
106 users' freedom, it does ensure that the user of a program that is
107 linked with the Library has the freedom and the wherewithal to run
108 that program using a modified version of the Library.
110 The precise terms and conditions for copying, distribution and
111 modification follow. Pay close attention to the difference between a
112 "work based on the library" and a "work that uses the library". The
113 former contains code derived from the library, whereas the latter must
114 be combined with the library in order to run.
116 GNU LESSER GENERAL PUBLIC LICENSE
117 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
119 0. This License Agreement applies to any software library or other
120 program which contains a notice placed by the copyright holder or
121 other authorized party saying it may be distributed under the terms of
122 this Lesser General Public License (also called "this License").
123 Each licensee is addressed as "you".
125 A "library" means a collection of software functions and/or data
126 prepared so as to be conveniently linked with application programs
127 (which use some of those functions and data) to form executables.
129 The "Library", below, refers to any such software library or work
130 which has been distributed under these terms. A "work based on the
131 Library" means either the Library or any derivative work under
132 copyright law: that is to say, a work containing the Library or a
133 portion of it, either verbatim or with modifications and/or translated
134 straightforwardly into another language. (Hereinafter, translation is
135 included without limitation in the term "modification".)
137 "Source code" for a work means the preferred form of the work for
138 making modifications to it. For a library, complete source code means
139 all the source code for all modules it contains, plus any associated
140 interface definition files, plus the scripts used to control
141 compilation and installation of the library.
143 Activities other than copying, distribution and modification are not
144 covered by this License; they are outside its scope. The act of
145 running a program using the Library is not restricted, and output from
146 such a program is covered only if its contents constitute a work based
147 on the Library (independent of the use of the Library in a tool for
148 writing it). Whether that is true depends on what the Library does
149 and what the program that uses the Library does.
151 1. You may copy and distribute verbatim copies of the Library's
152 complete source code as you receive it, in any medium, provided that
153 you conspicuously and appropriately publish on each copy an
154 appropriate copyright notice and disclaimer of warranty; keep intact
155 all the notices that refer to this License and to the absence of any
156 warranty; and distribute a copy of this License along with the
159 You may charge a fee for the physical act of transferring a copy,
160 and you may at your option offer warranty protection in exchange for a
163 2. You may modify your copy or copies of the Library or any portion
164 of it, thus forming a work based on the Library, and copy and
165 distribute such modifications or work under the terms of Section 1
166 above, provided that you also meet all of these conditions:
168 a) The modified work must itself be a software library.
170 b) You must cause the files modified to carry prominent notices
171 stating that you changed the files and the date of any change.
173 c) You must cause the whole of the work to be licensed at no
174 charge to all third parties under the terms of this License.
176 d) If a facility in the modified Library refers to a function or a
177 table of data to be supplied by an application program that uses
178 the facility, other than as an argument passed when the facility
179 is invoked, then you must make a good faith effort to ensure that,
180 in the event an application does not supply such function or
181 table, the facility still operates, and performs whatever part of
182 its purpose remains meaningful.
184 (For example, a function in a library to compute square roots has
185 a purpose that is entirely well-defined independent of the
186 application. Therefore, Subsection 2d requires that any
187 application-supplied function or table used by this function must
188 be optional: if the application does not supply it, the square
189 root function must still compute square roots.)
191 These requirements apply to the modified work as a whole. If
192 identifiable sections of that work are not derived from the Library,
193 and can be reasonably considered independent and separate works in
194 themselves, then this License, and its terms, do not apply to those
195 sections when you distribute them as separate works. But when you
196 distribute the same sections as part of a whole which is a work based
197 on the Library, the distribution of the whole must be on the terms of
198 this License, whose permissions for other licensees extend to the
199 entire whole, and thus to each and every part regardless of who wrote
202 Thus, it is not the intent of this section to claim rights or contest
203 your rights to work written entirely by you; rather, the intent is to
204 exercise the right to control the distribution of derivative or
205 collective works based on the Library.
207 In addition, mere aggregation of another work not based on the Library
208 with the Library (or with a work based on the Library) on a volume of
209 a storage or distribution medium does not bring the other work under
210 the scope of this License.
212 3. You may opt to apply the terms of the ordinary GNU General Public
213 License instead of this License to a given copy of the Library. To do
214 this, you must alter all the notices that refer to this License, so
215 that they refer to the ordinary GNU General Public License, version 2,
216 instead of to this License. (If a newer version than version 2 of the
217 ordinary GNU General Public License has appeared, then you can specify
218 that version instead if you wish.) Do not make any other change in
221 Once this change is made in a given copy, it is irreversible for
222 that copy, so the ordinary GNU General Public License applies to all
223 subsequent copies and derivative works made from that copy.
225 This option is useful when you wish to copy part of the code of
226 the Library into a program that is not a library.
228 4. You may copy and distribute the Library (or a portion or
229 derivative of it, under Section 2) in object code or executable form
230 under the terms of Sections 1 and 2 above provided that you accompany
231 it with the complete corresponding machine-readable source code, which
232 must be distributed under the terms of Sections 1 and 2 above on a
233 medium customarily used for software interchange.
235 If distribution of object code is made by offering access to copy
236 from a designated place, then offering equivalent access to copy the
237 source code from the same place satisfies the requirement to
238 distribute the source code, even though third parties are not
239 compelled to copy the source along with the object code.
241 5. A program that contains no derivative of any portion of the
242 Library, but is designed to work with the Library by being compiled or
243 linked with it, is called a "work that uses the Library". Such a
244 work, in isolation, is not a derivative work of the Library, and
245 therefore falls outside the scope of this License.
247 However, linking a "work that uses the Library" with the Library
248 creates an executable that is a derivative of the Library (because it
249 contains portions of the Library), rather than a "work that uses the
250 library". The executable is therefore covered by this License.
251 Section 6 states terms for distribution of such executables.
253 When a "work that uses the Library" uses material from a header file
254 that is part of the Library, the object code for the work may be a
255 derivative work of the Library even though the source code is not.
256 Whether this is true is especially significant if the work can be
257 linked without the Library, or if the work is itself a library. The
258 threshold for this to be true is not precisely defined by law.
260 If such an object file uses only numerical parameters, data
261 structure layouts and accessors, and small macros and small inline
262 functions (ten lines or less in length), then the use of the object
263 file is unrestricted, regardless of whether it is legally a derivative
264 work. (Executables containing this object code plus portions of the
265 Library will still fall under Section 6.)
267 Otherwise, if the work is a derivative of the Library, you may
268 distribute the object code for the work under the terms of Section 6.
269 Any executables containing that work also fall under Section 6,
270 whether or not they are linked directly with the Library itself.
272 6. As an exception to the Sections above, you may also combine or
273 link a "work that uses the Library" with the Library to produce a
274 work containing portions of the Library, and distribute that work
275 under terms of your choice, provided that the terms permit
276 modification of the work for the customer's own use and reverse
277 engineering for debugging such modifications.
279 You must give prominent notice with each copy of the work that the
280 Library is used in it and that the Library and its use are covered by
281 this License. You must supply a copy of this License. If the work
282 during execution displays copyright notices, you must include the
283 copyright notice for the Library among them, as well as a reference
284 directing the user to the copy of this License. Also, you must do one
287 a) Accompany the work with the complete corresponding
288 machine-readable source code for the Library including whatever
289 changes were used in the work (which must be distributed under
290 Sections 1 and 2 above); and, if the work is an executable linked
291 with the Library, with the complete machine-readable "work that
292 uses the Library", as object code and/or source code, so that the
293 user can modify the Library and then relink to produce a modified
294 executable containing the modified Library. (It is understood
295 that the user who changes the contents of definitions files in the
296 Library will not necessarily be able to recompile the application
297 to use the modified definitions.)
299 b) Use a suitable shared library mechanism for linking with the
300 Library. A suitable mechanism is one that (1) uses at run time a
301 copy of the library already present on the user's computer system,
302 rather than copying library functions into the executable, and (2)
303 will operate properly with a modified version of the library, if
304 the user installs one, as long as the modified version is
305 interface-compatible with the version that the work was made with.
307 c) Accompany the work with a written offer, valid for at least
308 three years, to give the same user the materials specified in
309 Subsection 6a, above, for a charge no more than the cost of
310 performing this distribution.
312 d) If distribution of the work is made by offering access to copy
313 from a designated place, offer equivalent access to copy the above
314 specified materials from the same place.
316 e) Verify that the user has already received a copy of these
317 materials or that you have already sent this user a copy.
319 For an executable, the required form of the "work that uses the
320 Library" must include any data and utility programs needed for
321 reproducing the executable from it. However, as a special exception,
322 the materials to be distributed need not include anything that is
323 normally distributed (in either source or binary form) with the major
324 components (compiler, kernel, and so on) of the operating system on
325 which the executable runs, unless that component itself accompanies
328 It may happen that this requirement contradicts the license
329 restrictions of other proprietary libraries that do not normally
330 accompany the operating system. Such a contradiction means you cannot
331 use both them and the Library together in an executable that you
334 7. You may place library facilities that are a work based on the
335 Library side-by-side in a single library together with other library
336 facilities not covered by this License, and distribute such a combined
337 library, provided that the separate distribution of the work based on
338 the Library and of the other library facilities is otherwise
339 permitted, and provided that you do these two things:
341 a) Accompany the combined library with a copy of the same work
342 based on the Library, uncombined with any other library
343 facilities. This must be distributed under the terms of the
346 b) Give prominent notice with the combined library of the fact
347 that part of it is a work based on the Library, and explaining
348 where to find the accompanying uncombined form of the same work.
350 8. You may not copy, modify, sublicense, link with, or distribute
351 the Library except as expressly provided under this License. Any
352 attempt otherwise to copy, modify, sublicense, link with, or
353 distribute the Library is void, and will automatically terminate your
354 rights under this License. However, parties who have received copies,
355 or rights, from you under this License will not have their licenses
356 terminated so long as such parties remain in full compliance.
358 9. You are not required to accept this License, since you have not
359 signed it. However, nothing else grants you permission to modify or
360 distribute the Library or its derivative works. These actions are
361 prohibited by law if you do not accept this License. Therefore, by
362 modifying or distributing the Library (or any work based on the
363 Library), you indicate your acceptance of this License to do so, and
364 all its terms and conditions for copying, distributing or modifying
365 the Library or works based on it.
367 10. Each time you redistribute the Library (or any work based on the
368 Library), the recipient automatically receives a license from the
369 original licensor to copy, distribute, link with or modify the Library
370 subject to these terms and conditions. You may not impose any further
371 restrictions on the recipients' exercise of the rights granted herein.
372 You are not responsible for enforcing compliance by third parties with
375 11. If, as a consequence of a court judgment or allegation of patent
376 infringement or for any other reason (not limited to patent issues),
377 conditions are imposed on you (whether by court order, agreement or
378 otherwise) that contradict the conditions of this License, they do not
379 excuse you from the conditions of this License. If you cannot
380 distribute so as to satisfy simultaneously your obligations under this
381 License and any other pertinent obligations, then as a consequence you
382 may not distribute the Library at all. For example, if a patent
383 license would not permit royalty-free redistribution of the Library by
384 all those who receive copies directly or indirectly through you, then
385 the only way you could satisfy both it and this License would be to
386 refrain entirely from distribution of the Library.
388 If any portion of this section is held invalid or unenforceable under
389 any particular circumstance, the balance of the section is intended to
390 apply, and the section as a whole is intended to apply in other
393 It is not the purpose of this section to induce you to infringe any
394 patents or other property right claims or to contest validity of any
395 such claims; this section has the sole purpose of protecting the
396 integrity of the free software distribution system which is
397 implemented by public license practices. Many people have made
398 generous contributions to the wide range of software distributed
399 through that system in reliance on consistent application of that
400 system; it is up to the author/donor to decide if he or she is willing
401 to distribute software through any other system and a licensee cannot
404 This section is intended to make thoroughly clear what is believed to
405 be a consequence of the rest of this License.
407 12. If the distribution and/or use of the Library is restricted in
408 certain countries either by patents or by copyrighted interfaces, the
409 original copyright holder who places the Library under this License
410 may add an explicit geographical distribution limitation excluding those
411 countries, so that distribution is permitted only in or among
412 countries not thus excluded. In such case, this License incorporates
413 the limitation as if written in the body of this License.
415 13. The Free Software Foundation may publish revised and/or new
416 versions of the Lesser General Public License from time to time.
417 Such new versions will be similar in spirit to the present version,
418 but may differ in detail to address new problems or concerns.
420 Each version is given a distinguishing version number. If the Library
421 specifies a version number of this License which applies to it and
422 "any later version", you have the option of following the terms and
423 conditions either of that version or of any later version published by
424 the Free Software Foundation. If the Library does not specify a
425 license version number, you may choose any version ever published by
426 the Free Software Foundation.
428 14. If you wish to incorporate parts of the Library into other free
429 programs whose distribution conditions are incompatible with these,
430 write to the author to ask for permission. For software which is
431 copyrighted by the Free Software Foundation, write to the Free
432 Software Foundation; we sometimes make exceptions for this. Our
433 decision will be guided by the two goals of preserving the free status
434 of all derivatives of our free software and of promoting the sharing
435 and reuse of software generally.
439 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
440 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
441 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
442 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
443 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
444 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
445 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
446 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
447 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
449 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
450 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
451 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
452 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
453 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
454 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
455 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
456 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
457 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
460 END OF TERMS AND CONDITIONS
462 How to Apply These Terms to Your New Libraries
464 If you develop a new library, and you want it to be of the greatest
465 possible use to the public, we recommend making it free software that
466 everyone can redistribute and change. You can do so by permitting
467 redistribution under these terms (or, alternatively, under the terms
468 of the ordinary General Public License).
470 To apply these terms, attach the following notices to the library.
471 It is safest to attach them to the start of each source file to most
472 effectively convey the exclusion of warranty; and each file should
473 have at least the "copyright" line and a pointer to where the full
477 <one line to give the library's name and a brief idea of what it does.>
478 Copyright (C) <year> <name of author>
480 This library is free software; you can redistribute it and/or
481 modify it under the terms of the GNU Lesser General Public
482 License as published by the Free Software Foundation; either
483 version 2.1 of the License, or (at your option) any later version.
485 This library is distributed in the hope that it will be useful,
486 but WITHOUT ANY WARRANTY; without even the implied warranty of
487 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
488 Lesser General Public License for more details.
490 You should have received a copy of the GNU Lesser General Public
491 License along with this library; if not, write to the Free Software
492 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
494 Also add information on how to contact you by electronic and paper mail.
496 You should also get your employer (if you work as a programmer) or
497 your school, if any, to sign a "copyright disclaimer" for the library,
498 if necessary. Here is a sample; alter the names:

511 GNU GENERAL PUBLIC LICENSE
514 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
515 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
516 Everyone is permitted to copy and distribute verbatim copies
517 of this license document, but changing it is not allowed.
521 The licenses for most software are designed to take away your
522 freedom to share and change it. By contrast, the GNU General Public
523 License is intended to guarantee your freedom to share and change free
524 software--to make sure the software is free for all its users. This
525 General Public License applies to most of the Free Software
526 Foundation's software and to any other program whose authors commit to
527 using it. (Some other Free Software Foundation software is covered by
528 the GNU Lesser General Public License instead.) You can apply it to
531 When we speak of free software, we are referring to freedom, not
532 price. Our General Public Licenses are designed to make sure that you
533 have the freedom to distribute copies of free software (and charge for
534 this service if you wish), that you receive source code or can get it
535 if you want it, that you can change the software or use pieces of it
536 in new free programs; and that you know you can do these things.
538 To protect your rights, we need to make restrictions that forbid
539 anyone to deny you these rights or to ask you to surrender the rights.
540 These restrictions translate to certain responsibilities for you if you
541 distribute copies of the software, or if you modify it.
543 For example, if you distribute copies of such a program, whether
544 gratis or for a fee, you must give the recipients all the rights that
545 you have. You must make sure that they, too, receive or can get the
546 source code. And you must show them these terms so they know their
549 We protect your rights with two steps: (1) copyright the software, and
550 (2) offer you this license which gives you legal permission to copy,
551 distribute and/or modify the software.
553 Also, for each author's protection and ours, we want to make certain
554 that everyone understands that there is no warranty for this free
555 software. If the software is modified by someone else and passed on, we
556 want its recipients to know that what they have is not the original, so
557 that any problems introduced by others will not reflect on the original
558 authors' reputations.
560 Finally, any free program is threatened constantly by software
561 patents. We wish to avoid the danger that redistributors of a free
562 program will individually obtain patent licenses, in effect making the
563 program proprietary. To prevent this, we have made it clear that any
564 patent must be licensed for everyone's free use or not licensed at all.
566 The precise terms and conditions for copying, distribution and
569 GNU GENERAL PUBLIC LICENSE
570 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
572 0. This License applies to any program or other work which contains
573 a notice placed by the copyright holder saying it may be distributed
574 under the terms of this General Public License. The "Program", below,
575 refers to any such program or work, and a "work based on the Program"
576 means either the Program or any derivative work under copyright law:
577 that is to say, a work containing the Program or a portion of it,
578 either verbatim or with modifications and/or translated into another
579 language. (Hereinafter, translation is included without limitation in
580 the term "modification".) Each licensee is addressed as "you".
582 Activities other than copying, distribution and modification are not
583 covered by this License; they are outside its scope. The act of
584 running the Program is not restricted, and the output from the Program
585 is covered only if its contents constitute a work based on the
586 Program (independent of having been made by running the Program).
587 Whether that is true depends on what the Program does.
589 1. You may copy and distribute verbatim copies of the Program's
590 source code as you receive it, in any medium, provided that you
591 conspicuously and appropriately publish on each copy an appropriate
592 copyright notice and disclaimer of warranty; keep intact all the
593 notices that refer to this License and to the absence of any warranty;
594 and give any other recipients of the Program a copy of this License
595 along with the Program.
597 You may charge a fee for the physical act of transferring a copy, and
598 you may at your option offer warranty protection in exchange for a fee.
600 2. You may modify your copy or copies of the Program or any portion
601 of it, thus forming a work based on the Program, and copy and
602 distribute such modifications or work under the terms of Section 1
603 above, provided that you also meet all of these conditions:
605 a) You must cause the modified files to carry prominent notices
606 stating that you changed the files and the date of any change.
608 b) You must cause any work that you distribute or publish, that in
609 whole or in part contains or is derived from the Program or any
610 part thereof, to be licensed as a whole at no charge to all third
611 parties under the terms of this License.
613 c) If the modified program normally reads commands interactively
614 when run, you must cause it, when started running for such
615 interactive use in the most ordinary way, to print or display an
616 announcement including an appropriate copyright notice and a
617 notice that there is no warranty (or else, saying that you provide
618 a warranty) and that users may redistribute the program under
619 these conditions, and telling the user how to view a copy of this
620 License. (Exception: if the Program itself is interactive but
621 does not normally print such an announcement, your work based on
622 the Program is not required to print an announcement.)
624 These requirements apply to the modified work as a whole. If
625 identifiable sections of that work are not derived from the Program,
626 and can be reasonably considered independent and separate works in
627 themselves, then this License, and its terms, do not apply to those
628 sections when you distribute them as separate works. But when you
629 distribute the same sections as part of a whole which is a work based
630 on the Program, the distribution of the whole must be on the terms of
631 this License, whose permissions for other licensees extend to the
632 entire whole, and thus to each and every part regardless of who wrote it.
634 Thus, it is not the intent of this section to claim rights or contest
635 your rights to work written entirely by you; rather, the intent is to
636 exercise the right to control the distribution of derivative or
637 collective works based on the Program.
639 In addition, mere aggregation of another work not based on the Program
640 with the Program (or with a work based on the Program) on a volume of
641 a storage or distribution medium does not bring the other work under
642 the scope of this License.
644 3. You may copy and distribute the Program (or a work based on it,
645 under Section 2) in object code or executable form under the terms of
646 Sections 1 and 2 above provided that you also do one of the following:
648 a) Accompany it with the complete corresponding machine-readable
649 source code, which must be distributed under the terms of Sections
650 1 and 2 above on a medium customarily used for software interchange; or,
652 b) Accompany it with a written offer, valid for at least three
653 years, to give any third party, for a charge no more than your
654 cost of physically performing source distribution, a complete
655 machine-readable copy of the corresponding source code, to be
656 distributed under the terms of Sections 1 and 2 above on a medium
657 customarily used for software interchange; or,
659 c) Accompany it with the information you received as to the offer
660 to distribute corresponding source code. (This alternative is
661 allowed only for noncommercial distribution and only if you
662 received the program in object code or executable form with such
663 an offer, in accord with Subsection b above.)
665 The source code for a work means the preferred form of the work for
666 making modifications to it. For an executable work, complete source
667 code means all the source code for all modules it contains, plus any
668 associated interface definition files, plus the scripts used to
669 control compilation and installation of the executable. However, as a
670 special exception, the source code distributed need not include
671 anything that is normally distributed (in either source or binary
672 form) with the major components (compiler, kernel, and so on) of the
673 operating system on which the executable runs, unless that component
674 itself accompanies the executable.
676 If distribution of executable or object code is made by offering
677 access to copy from a designated place, then offering equivalent
678 access to copy the source code from the same place counts as
679 distribution of the source code, even though third parties are not
680 compelled to copy the source along with the object code.
682 4. You may not copy, modify, sublicense, or distribute the Program
683 except as expressly provided under this License. Any attempt
684 otherwise to copy, modify, sublicense or distribute the Program is
685 void, and will automatically terminate your rights under this License.
686 However, parties who have received copies, or rights, from you under
687 this License will not have their licenses terminated so long as such
688 parties remain in full compliance.
690 5. You are not required to accept this License, since you have not
691 signed it. However, nothing else grants you permission to modify or
692 distribute the Program or its derivative works. These actions are
693 prohibited by law if you do not accept this License. Therefore, by
694 modifying or distributing the Program (or any work based on the
695 Program), you indicate your acceptance of this License to do so, and
696 all its terms and conditions for copying, distributing or modifying
697 the Program or works based on it.
699 6. Each time you redistribute the Program (or any work based on the
700 Program), the recipient automatically receives a license from the
701 original licensor to copy, distribute or modify the Program subject to
702 these terms and conditions. You may not impose any further
703 restrictions on the recipients' exercise of the rights granted herein.
704 You are not responsible for enforcing compliance by third parties to
707 7. If, as a consequence of a court judgment or allegation of patent
708 infringement or for any other reason (not limited to patent issues),
709 conditions are imposed on you (whether by court order, agreement or
710 otherwise) that contradict the conditions of this License, they do not
711 excuse you from the conditions of this License. If you cannot
712 distribute so as to satisfy simultaneously your obligations under this
713 License and any other pertinent obligations, then as a consequence you
714 may not distribute the Program at all. For example, if a patent
715 license would not permit royalty-free redistribution of the Program by
716 all those who receive copies directly or indirectly through you, then
717 the only way you could satisfy both it and this License would be to
718 refrain entirely from distribution of the Program.
720 If any portion of this section is held invalid or unenforceable under
721 any particular circumstance, the balance of the section is intended to
722 apply and the section as a whole is intended to apply in other
725 It is not the purpose of this section to induce you to infringe any
726 patents or other property right claims or to contest validity of any
727 such claims; this section has the sole purpose of protecting the
728 integrity of the free software distribution system, which is
729 implemented by public license practices. Many people have made
730 generous contributions to the wide range of software distributed
731 through that system in reliance on consistent application of that
732 system; it is up to the author/donor to decide if he or she is willing
733 to distribute software through any other system and a licensee cannot
736 This section is intended to make thoroughly clear what is believed to
737 be a consequence of the rest of this License.
739 8. If the distribution and/or use of the Program is restricted in
740 certain countries either by patents or by copyrighted interfaces, the
741 original copyright holder who places the Program under this License
742 may add an explicit geographical distribution limitation excluding
743 those countries, so that distribution is permitted only in or among
744 countries not thus excluded. In such case, this License incorporates
745 the limitation as if written in the body of this License.
747 9. The Free Software Foundation may publish revised and/or new versions
748 of the General Public License from time to time. Such new versions will
749 be similar in spirit to the present version, but may differ in detail to
750 address new problems or concerns.
752 Each version is given a distinguishing version number. If the Program
753 specifies a version number of this License which applies to it and "any
754 later version", you have the option of following the terms and conditions
755 either of that version or of any later version published by the Free
756 Software Foundation. If the Program does not specify a version number of
757 this License, you may choose any version ever published by the Free Software
760 10. If you wish to incorporate parts of the Program into other free
761 programs whose distribution conditions are different, write to the author
762 to ask for permission. For software which is copyrighted by the Free
763 Software Foundation, write to the Free Software Foundation; we sometimes
764 make exceptions for this. Our decision will be guided by the two goals
765 of preserving the free status of all derivatives of our free software and
766 of promoting the sharing and reuse of software generally.
770 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
771 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
772 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
773 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
774 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
775 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
776 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
777 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
778 REPAIR OR CORRECTION.
780 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
781 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
782 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
783 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
784 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
785 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
786 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
787 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
788 POSSIBILITY OF SUCH DAMAGES.
790 END OF TERMS AND CONDITIONS
792 How to Apply These Terms to Your New Programs
794 If you develop a new program, and you want it to be of the greatest
795 possible use to the public, the best way to achieve this is to make it
796 free software which everyone can redistribute and change under these terms.
798 To do so, attach the following notices to the program. It is safest
799 to attach them to the start of each source file to most effectively
800 convey the exclusion of warranty; and each file should have at least
801 the "copyright" line and a pointer to where the full notice is found.
803 <one line to give the program's name and a brief idea of what it does.>
804 Copyright (C) <year> <name of author>
806 This program is free software; you can redistribute it and/or modify
807 it under the terms of the GNU General Public License as published by
808 the Free Software Foundation; either version 2 of the License, or
809 (at your option) any later version.
811 This program is distributed in the hope that it will be useful,
812 but WITHOUT ANY WARRANTY; without even the implied warranty of
813 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
814 GNU General Public License for more details.
816 You should have received a copy of the GNU General Public License along
817 with this program; if not, write to the Free Software Foundation, Inc.,
818 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
820 Also add information on how to contact you by electronic and paper mail.
822 If the program is interactive, make it output a short notice like this
823 when it starts in an interactive mode:
825 Gnomovision version 69, Copyright (C) year name of author
826 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
827 This is free software, and you are welcome to redistribute it
828 under certain conditions; type `show c' for details.
830 The hypothetical commands `show w' and `show c' should show the appropriate
831 parts of the General Public License. Of course, the commands you use may
832 be called something other than `show w' and `show c'; they could even be
833 mouse-clicks or menu items--whatever suits your program.
835 You should also get your employer (if you work as a programmer) or your
836 school, if any, to sign a "copyright disclaimer" for the program, if
837 necessary. Here is a sample; alter the names:
839 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
840 `Gnomovision' (which makes passes at compilers) written by James Hacker.

845 This General Public License does not permit incorporating your program into
846 proprietary programs. If your program is a subroutine library, you may
847 consider it more useful to permit linking proprietary applications with the
848 library. If this is what you want to do, use the GNU Lesser General
849 Public License instead of this License.
