177 Everyone is permitted to copy and distribute verbatim copies
178 of this license document, but changing it is not allowed.
182 The licenses for most software are designed to take away your
183 freedom to share and change it. By contrast, the GNU General Public
184 License is intended to guarantee your freedom to share and change free
185 software--to make sure the software is free for all its users. This
186 General Public License applies to most of the Free Software
187 Foundation's software and to any other program whose authors commit to
188 using it. (Some other Free Software Foundation software is covered by
189 the GNU Library General Public License instead.) You can apply it to
192 When we speak of free software, we are referring to freedom, not
193 price. Our General Public Licenses are designed to make sure that you
194 have the freedom to distribute copies of free software (and charge for
195 this service if you wish), that you receive source code or can get it
196 if you want it, that you can change the software or use pieces of it
197 in new free programs; and that you know you can do these things.
199 To protect your rights, we need to make restrictions that forbid
200 anyone to deny you these rights or to ask you to surrender the rights.
201 These restrictions translate to certain responsibilities for you if you
202 distribute copies of the software, or if you modify it.
204 For example, if you distribute copies of such a program, whether
205 gratis or for a fee, you must give the recipients all the rights that
206 you have. You must make sure that they, too, receive or can get the
207 source code. And you must show them these terms so they know their
210 We protect your rights with two steps: (1) copyright the software, and
211 (2) offer you this license which gives you legal permission to copy,
212 distribute and/or modify the software.
214 Also, for each author's protection and ours, we want to make certain
215 that everyone understands that there is no warranty for this free
216 software. If the software is modified by someone else and passed on, we
217 want its recipients to know that what they have is not the original, so
218 that any problems introduced by others will not reflect on the original
219 authors' reputations.
221 Finally, any free program is threatened constantly by software
222 patents. We wish to avoid the danger that redistributors of a free
223 program will individually obtain patent licenses, in effect making the
224 program proprietary. To prevent this, we have made it clear that any
225 patent must be licensed for everyone's free use or not licensed at all.
227 The precise terms and conditions for copying, distribution and
230 GNU GENERAL PUBLIC LICENSE
231 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
233 0. This License applies to any program or other work which contains
234 a notice placed by the copyright holder saying it may be distributed
235 under the terms of this General Public License. The "Program", below,
236 refers to any such program or work, and a "work based on the Program"
237 means either the Program or any derivative work under copyright law:
238 that is to say, a work containing the Program or a portion of it,
239 either verbatim or with modifications and/or translated into another
240 language. (Hereinafter, translation is included without limitation in
241 the term "modification".) Each licensee is addressed as "you".
243 Activities other than copying, distribution and modification are not
244 covered by this License; they are outside its scope. The act of
245 running the Program is not restricted, and the output from the Program
246 is covered only if its contents constitute a work based on the
247 Program (independent of having been made by running the Program).
248 Whether that is true depends on what the Program does.
250 1. You may copy and distribute verbatim copies of the Program's
251 source code as you receive it, in any medium, provided that you
252 conspicuously and appropriately publish on each copy an appropriate
253 copyright notice and disclaimer of warranty; keep intact all the
254 notices that refer to this License and to the absence of any warranty;
255 and give any other recipients of the Program a copy of this License
256 along with the Program.
258 You may charge a fee for the physical act of transferring a copy, and
259 you may at your option offer warranty protection in exchange for a fee.
261 2. You may modify your copy or copies of the Program or any portion
262 of it, thus forming a work based on the Program, and copy and
263 distribute such modifications or work under the terms of Section 1
264 above, provided that you also meet all of these conditions:
266 a) You must cause the modified files to carry prominent notices
267 stating that you changed the files and the date of any change.
269 b) You must cause any work that you distribute or publish, that in
270 whole or in part contains or is derived from the Program or any
271 part thereof, to be licensed as a whole at no charge to all third
272 parties under the terms of this License.
274 c) If the modified program normally reads commands interactively
275 when run, you must cause it, when started running for such
276 interactive use in the most ordinary way, to print or display an
277 announcement including an appropriate copyright notice and a
278 notice that there is no warranty (or else, saying that you provide
279 a warranty) and that users may redistribute the program under
280 these conditions, and telling the user how to view a copy of this
281 License. (Exception: if the Program itself is interactive but
282 does not normally print such an announcement, your work based on
283 the Program is not required to print an announcement.)
285 These requirements apply to the modified work as a whole. If
286 identifiable sections of that work are not derived from the Program,
287 and can be reasonably considered independent and separate works in
288 themselves, then this License, and its terms, do not apply to those
289 sections when you distribute them as separate works. But when you
290 distribute the same sections as part of a whole which is a work based
291 on the Program, the distribution of the whole must be on the terms of
292 this License, whose permissions for other licensees extend to the
293 entire whole, and thus to each and every part regardless of who wrote it.
295 Thus, it is not the intent of this section to claim rights or contest
296 your rights to work written entirely by you; rather, the intent is to
297 exercise the right to control the distribution of derivative or
298 collective works based on the Program.
300 In addition, mere aggregation of another work not based on the Program
301 with the Program (or with a work based on the Program) on a volume of
302 a storage or distribution medium does not bring the other work under
303 the scope of this License.
305 3. You may copy and distribute the Program (or a work based on it,
306 under Section 2) in object code or executable form under the terms of
307 Sections 1 and 2 above provided that you also do one of the following:
309 a) Accompany it with the complete corresponding machine-readable
310 source code, which must be distributed under the terms of Sections
311 1 and 2 above on a medium customarily used for software interchange; or,
313 b) Accompany it with a written offer, valid for at least three
314 years, to give any third party, for a charge no more than your
315 cost of physically performing source distribution, a complete
316 machine-readable copy of the corresponding source code, to be
317 distributed under the terms of Sections 1 and 2 above on a medium
318 customarily used for software interchange; or,
320 c) Accompany it with the information you received as to the offer
321 to distribute corresponding source code. (This alternative is
322 allowed only for noncommercial distribution and only if you
323 received the program in object code or executable form with such
324 an offer, in accord with Subsection b above.)
326 The source code for a work means the preferred form of the work for
327 making modifications to it. For an executable work, complete source
328 code means all the source code for all modules it contains, plus any
329 associated interface definition files, plus the scripts used to
330 control compilation and installation of the executable. However, as a
331 special exception, the source code distributed need not include
332 anything that is normally distributed (in either source or binary
333 form) with the major components (compiler, kernel, and so on) of the
334 operating system on which the executable runs, unless that component
335 itself accompanies the executable.
337 If distribution of executable or object code is made by offering
338 access to copy from a designated place, then offering equivalent
339 access to copy the source code from the same place counts as
340 distribution of the source code, even though third parties are not
341 compelled to copy the source along with the object code.
343 4. You may not copy, modify, sublicense, or distribute the Program
344 except as expressly provided under this License. Any attempt
345 otherwise to copy, modify, sublicense or distribute the Program is
346 void, and will automatically terminate your rights under this License.
347 However, parties who have received copies, or rights, from you under
348 this License will not have their licenses terminated so long as such
349 parties remain in full compliance.
351 5. You are not required to accept this License, since you have not
352 signed it. However, nothing else grants you permission to modify or
353 distribute the Program or its derivative works. These actions are
354 prohibited by law if you do not accept this License. Therefore, by
355 modifying or distributing the Program (or any work based on the
356 Program), you indicate your acceptance of this License to do so, and
357 all its terms and conditions for copying, distributing or modifying
358 the Program or works based on it.
360 6. Each time you redistribute the Program (or any work based on the
361 Program), the recipient automatically receives a license from the
362 original licensor to copy, distribute or modify the Program subject to
363 these terms and conditions. You may not impose any further
364 restrictions on the recipients' exercise of the rights granted herein.
365 You are not responsible for enforcing compliance by third parties to
368 7. If, as a consequence of a court judgment or allegation of patent
369 infringement or for any other reason (not limited to patent issues),
370 conditions are imposed on you (whether by court order, agreement or
371 otherwise) that contradict the conditions of this License, they do not
372 excuse you from the conditions of this License. If you cannot
373 distribute so as to satisfy simultaneously your obligations under this
374 License and any other pertinent obligations, then as a consequence you
375 may not distribute the Program at all. For example, if a patent
376 license would not permit royalty-free redistribution of the Program by
377 all those who receive copies directly or indirectly through you, then
378 the only way you could satisfy both it and this License would be to
379 refrain entirely from distribution of the Program.
381 If any portion of this section is held invalid or unenforceable under
382 any particular circumstance, the balance of the section is intended to
383 apply and the section as a whole is intended to apply in other
386 It is not the purpose of this section to induce you to infringe any
387 patents or other property right claims or to contest validity of any
388 such claims; this section has the sole purpose of protecting the
389 integrity of the free software distribution system, which is
390 implemented by public license practices. Many people have made
391 generous contributions to the wide range of software distributed
392 through that system in reliance on consistent application of that
393 system; it is up to the author/donor to decide if he or she is willing
394 to distribute software through any other system and a licensee cannot
397 This section is intended to make thoroughly clear what is believed to
398 be a consequence of the rest of this License.
400 8. If the distribution and/or use of the Program is restricted in
401 certain countries either by patents or by copyrighted interfaces, the
402 original copyright holder who places the Program under this License
403 may add an explicit geographical distribution limitation excluding
404 those countries, so that distribution is permitted only in or among
405 countries not thus excluded. In such case, this License incorporates
406 the limitation as if written in the body of this License.
408 9. The Free Software Foundation may publish revised and/or new versions
409 of the General Public License from time to time. Such new versions will
410 be similar in spirit to the present version, but may differ in detail to
411 address new problems or concerns.
413 Each version is given a distinguishing version number. If the Program
414 specifies a version number of this License which applies to it and "any
415 later version", you have the option of following the terms and conditions
416 either of that version or of any later version published by the Free
417 Software Foundation. If the Program does not specify a version number of
418 this License, you may choose any version ever published by the Free Software
421 10. If you wish to incorporate parts of the Program into other free
422 programs whose distribution conditions are different, write to the author
423 to ask for permission. For software which is copyrighted by the Free
424 Software Foundation, write to the Free Software Foundation; we sometimes
425 make exceptions for this. Our decision will be guided by the two goals
426 of preserving the free status of all derivatives of our free software and
427 of promoting the sharing and reuse of software generally.
431 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
432 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
433 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
434 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
435 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
436 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
437 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
438 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
439 REPAIR OR CORRECTION.
441 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
442 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
443 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
444 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
445 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
446 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
447 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
448 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
449 POSSIBILITY OF SUCH DAMAGES.
451 END OF TERMS AND CONDITIONS
453 How to Apply These Terms to Your New Programs
455 If you develop a new program, and you want it to be of the greatest
456 possible use to the public, the best way to achieve this is to make it
457 free software which everyone can redistribute and change under these terms.
459 To do so, attach the following notices to the program. It is safest
460 to attach them to the start of each source file to most effectively
461 convey the exclusion of warranty; and each file should have at least
462 the "copyright" line and a pointer to where the full notice is found.
464 <one line to give the program's name and a brief idea of what it does.>
465 Copyright (C) <year> <name of author>
467 This program is free software; you can redistribute it and/or modify
468 it under the terms of the GNU General Public License as published by
469 the Free Software Foundation; either version 2 of the License, or
470 (at your option) any later version.
472 This program is distributed in the hope that it will be useful,
473 but WITHOUT ANY WARRANTY; without even the implied warranty of
474 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
475 GNU General Public License for more details.
477 You should have received a copy of the GNU General Public License
478 along with this program; if not, write to the Free Software
479 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
482 Also add information on how to contact you by electronic and paper mail.
484 If the program is interactive, make it output a short notice like this
485 when it starts in an interactive mode:
487 Gnomovision version 69, Copyright (C) year name of author
488 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
489 This is free software, and you are welcome to redistribute it
490 under certain conditions; type `show c' for details.
492 The hypothetical commands `show w' and `show c' should show the appropriate
493 parts of the General Public License. Of course, the commands you use may
494 be called something other than `show w' and `show c'; they could even be
495 mouse-clicks or menu items--whatever suits your program.
497 You should also get your employer (if you work as a programmer) or your
498 school, if any, to sign a "copyright disclaimer" for the program, if
499 necessary. Here is a sample; alter the names:
501 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
502 `Gnomovision' (which makes passes at compilers) written by James Hacker.

507 This General Public License does not permit incorporating your program into
508 proprietary programs. If your program is a subroutine library, you may
509 consider it more useful to permit linking proprietary applications with the
510 library. If this is what you want to do, use the GNU Library General
511 Public License instead of this License.
