25 Everyone is permitted to copy and distribute verbatim copies
26 of this license document, but changing it is not allowed.
31 <H2><A NAME="SEC3">Preamble</A></H2>
34 The licenses for most software are designed to take away your
35 freedom to share and change it. By contrast, the GNU General Public
36 License is intended to guarantee your freedom to share and change free
37 software--to make sure the software is free for all its users. This
38 General Public License applies to most of the Free Software
39 Foundation's software and to any other program whose authors commit to
40 using it. (Some other Free Software Foundation software is covered by
41 the GNU Library General Public License instead.) You can apply it to
46 When we speak of free software, we are referring to freedom, not
47 price. Our General Public Licenses are designed to make sure that you
48 have the freedom to distribute copies of free software (and charge for
49 this service if you wish), that you receive source code or can get it
50 if you want it, that you can change the software or use pieces of it
51 in new free programs; and that you know you can do these things.
55 To protect your rights, we need to make restrictions that forbid
56 anyone to deny you these rights or to ask you to surrender the rights.
57 These restrictions translate to certain responsibilities for you if you
58 distribute copies of the software, or if you modify it.
62 For example, if you distribute copies of such a program, whether
63 gratis or for a fee, you must give the recipients all the rights that
64 you have. You must make sure that they, too, receive or can get the
65 source code. And you must show them these terms so they know their
70 We protect your rights with two steps: (1) copyright the software, and
71 (2) offer you this license which gives you legal permission to copy,
72 distribute and/or modify the software.
76 Also, for each author's protection and ours, we want to make certain
77 that everyone understands that there is no warranty for this free
78 software. If the software is modified by someone else and passed on, we
79 want its recipients to know that what they have is not the original, so
80 that any problems introduced by others will not reflect on the original
85 Finally, any free program is threatened constantly by software
86 patents. We wish to avoid the danger that redistributors of a free
87 program will individually obtain patent licenses, in effect making the
88 program proprietary. To prevent this, we have made it clear that any
89 patent must be licensed for everyone's free use or not licensed at all.
93 The precise terms and conditions for copying, distribution and
99 <H2><A NAME="SEC4">TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</A></H2>
105 This License applies to any program or other work which contains
106 a notice placed by the copyright holder saying it may be distributed
107 under the terms of this General Public License. The "Program", below,
108 refers to any such program or work, and a "work based on the Program"
109 means either the Program or any derivative work under copyright law:
110 that is to say, a work containing the Program or a portion of it,
111 either verbatim or with modifications and/or translated into another
112 language. (Hereinafter, translation is included without limitation in
113 the term "modification".) Each licensee is addressed as "you".
115 Activities other than copying, distribution and modification are not
116 covered by this License; they are outside its scope. The act of
117 running the Program is not restricted, and the output from the Program
118 is covered only if its contents constitute a work based on the
119 Program (independent of having been made by running the Program).
120 Whether that is true depends on what the Program does.
124 You may copy and distribute verbatim copies of the Program's
125 source code as you receive it, in any medium, provided that you
126 conspicuously and appropriately publish on each copy an appropriate
127 copyright notice and disclaimer of warranty; keep intact all the
128 notices that refer to this License and to the absence of any warranty;
129 and give any other recipients of the Program a copy of this License
130 along with the Program.
132 You may charge a fee for the physical act of transferring a copy, and
133 you may at your option offer warranty protection in exchange for a fee.
137 You may modify your copy or copies of the Program or any portion
138 of it, thus forming a work based on the Program, and copy and
139 distribute such modifications or work under the terms of Section 1
140 above, provided that you also meet all of these conditions:
146 You must cause the modified files to carry prominent notices
147 stating that you changed the files and the date of any change.
151 You must cause any work that you distribute or publish, that in
152 whole or in part contains or is derived from the Program or any
153 part thereof, to be licensed as a whole at no charge to all third
154 parties under the terms of this License.
158 If the modified program normally reads commands interactively
159 when run, you must cause it, when started running for such
160 interactive use in the most ordinary way, to print or display an
161 announcement including an appropriate copyright notice and a
162 notice that there is no warranty (or else, saying that you provide
163 a warranty) and that users may redistribute the program under
164 these conditions, and telling the user how to view a copy of this
165 License. (Exception: if the Program itself is interactive but
166 does not normally print such an announcement, your work based on
167 the Program is not required to print an announcement.)
170 These requirements apply to the modified work as a whole. If
171 identifiable sections of that work are not derived from the Program,
172 and can be reasonably considered independent and separate works in
173 themselves, then this License, and its terms, do not apply to those
174 sections when you distribute them as separate works. But when you
175 distribute the same sections as part of a whole which is a work based
176 on the Program, the distribution of the whole must be on the terms of
177 this License, whose permissions for other licensees extend to the
178 entire whole, and thus to each and every part regardless of who wrote it.
180 Thus, it is not the intent of this section to claim rights or contest
181 your rights to work written entirely by you; rather, the intent is to
182 exercise the right to control the distribution of derivative or
183 collective works based on the Program.
185 In addition, mere aggregation of another work not based on the Program
186 with the Program (or with a work based on the Program) on a volume of
187 a storage or distribution medium does not bring the other work under
188 the scope of this License.
192 You may copy and distribute the Program (or a work based on it,
193 under Section 2) in object code or executable form under the terms of
194 Sections 1 and 2 above provided that you also do one of the following:
200 Accompany it with the complete corresponding machine-readable
201 source code, which must be distributed under the terms of Sections
202 1 and 2 above on a medium customarily used for software interchange; or,
206 Accompany it with a written offer, valid for at least three
207 years, to give any third party, for a charge no more than your
208 cost of physically performing source distribution, a complete
209 machine-readable copy of the corresponding source code, to be
210 distributed under the terms of Sections 1 and 2 above on a medium
211 customarily used for software interchange; or,
215 Accompany it with the information you received as to the offer
216 to distribute corresponding source code. (This alternative is
217 allowed only for noncommercial distribution and only if you
218 received the program in object code or executable form with such
219 an offer, in accord with Subsection b above.)
222 The source code for a work means the preferred form of the work for
223 making modifications to it. For an executable work, complete source
224 code means all the source code for all modules it contains, plus any
225 associated interface definition files, plus the scripts used to
226 control compilation and installation of the executable. However, as a
227 special exception, the source code distributed need not include
228 anything that is normally distributed (in either source or binary
229 form) with the major components (compiler, kernel, and so on) of the
230 operating system on which the executable runs, unless that component
231 itself accompanies the executable.
233 If distribution of executable or object code is made by offering
234 access to copy from a designated place, then offering equivalent
235 access to copy the source code from the same place counts as
236 distribution of the source code, even though third parties are not
237 compelled to copy the source along with the object code.
241 You may not copy, modify, sublicense, or distribute the Program
242 except as expressly provided under this License. Any attempt
243 otherwise to copy, modify, sublicense or distribute the Program is
244 void, and will automatically terminate your rights under this License.
245 However, parties who have received copies, or rights, from you under
246 this License will not have their licenses terminated so long as such
247 parties remain in full compliance.
251 You are not required to accept this License, since you have not
252 signed it. However, nothing else grants you permission to modify or
253 distribute the Program or its derivative works. These actions are
254 prohibited by law if you do not accept this License. Therefore, by
255 modifying or distributing the Program (or any work based on the
256 Program), you indicate your acceptance of this License to do so, and
257 all its terms and conditions for copying, distributing or modifying
258 the Program or works based on it.
262 Each time you redistribute the Program (or any work based on the
263 Program), the recipient automatically receives a license from the
264 original licensor to copy, distribute or modify the Program subject to
265 these terms and conditions. You may not impose any further
266 restrictions on the recipients' exercise of the rights granted herein.
267 You are not responsible for enforcing compliance by third parties to
272 If, as a consequence of a court judgment or allegation of patent
273 infringement or for any other reason (not limited to patent issues),
274 conditions are imposed on you (whether by court order, agreement or
275 otherwise) that contradict the conditions of this License, they do not
276 excuse you from the conditions of this License. If you cannot
277 distribute so as to satisfy simultaneously your obligations under this
278 License and any other pertinent obligations, then as a consequence you
279 may not distribute the Program at all. For example, if a patent
280 license would not permit royalty-free redistribution of the Program by
281 all those who receive copies directly or indirectly through you, then
282 the only way you could satisfy both it and this License would be to
283 refrain entirely from distribution of the Program.
285 If any portion of this section is held invalid or unenforceable under
286 any particular circumstance, the balance of the section is intended to
287 apply and the section as a whole is intended to apply in other
290 It is not the purpose of this section to induce you to infringe any
291 patents or other property right claims or to contest validity of any
292 such claims; this section has the sole purpose of protecting the
293 integrity of the free software distribution system, which is
294 implemented by public license practices. Many people have made
295 generous contributions to the wide range of software distributed
296 through that system in reliance on consistent application of that
297 system; it is up to the author/donor to decide if he or she is willing
298 to distribute software through any other system and a licensee cannot
301 This section is intended to make thoroughly clear what is believed to
302 be a consequence of the rest of this License.
306 If the distribution and/or use of the Program is restricted in
307 certain countries either by patents or by copyrighted interfaces, the
308 original copyright holder who places the Program under this License
309 may add an explicit geographical distribution limitation excluding
310 those countries, so that distribution is permitted only in or among
311 countries not thus excluded. In such case, this License incorporates
312 the limitation as if written in the body of this License.
316 The Free Software Foundation may publish revised and/or new versions
317 of the General Public License from time to time. Such new versions will
318 be similar in spirit to the present version, but may differ in detail to
319 address new problems or concerns.
321 Each version is given a distinguishing version number. If the Program
322 specifies a version number of this License which applies to it and "any
323 later version", you have the option of following the terms and conditions
324 either of that version or of any later version published by the Free
325 Software Foundation. If the Program does not specify a version number of
326 this License, you may choose any version ever published by the Free Software
331 If you wish to incorporate parts of the Program into other free
332 programs whose distribution conditions are different, write to the author
333 to ask for permission. For software which is copyrighted by the Free
334 Software Foundation, write to the Free Software Foundation; we sometimes
335 make exceptions for this. Our decision will be guided by the two goals
336 of preserving the free status of all derivatives of our free software and
337 of promoting the sharing and reuse of software generally.
341 <P><STRONG>NO WARRANTY</STRONG>
345 BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
346 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
347 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
348 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
349 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
350 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
351 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
352 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
353 REPAIR OR CORRECTION.
357 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
358 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
359 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
360 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
361 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
362 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
363 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
364 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
365 POSSIBILITY OF SUCH DAMAGES.
369 <H2>END OF TERMS AND CONDITIONS</H2>
373 <H2><A NAME="SEC5">How to Apply These Terms to Your New Programs</A></H2>
376 If you develop a new program, and you want it to be of the greatest
377 possible use to the public, the best way to achieve this is to make it
378 free software which everyone can redistribute and change under these terms.
382 To do so, attach the following notices to the program. It is safest
383 to attach them to the start of each source file to most effectively
384 convey the exclusion of warranty; and each file should have at least
385 the "copyright" line and a pointer to where the full notice is found.
390 <VAR>one line to give the program's name and a brief idea of what it does.</VAR>
391 Copyright (C) 19<VAR>yy</VAR> <VAR>name of author</VAR>
393 This program is free software; you can redistribute it and/or modify
394 it under the terms of the GNU General Public License as published by
395 the Free Software Foundation; either version 2 of the License, or
396 (at your option) any later version.
398 This program is distributed in the hope that it will be useful,
399 but WITHOUT ANY WARRANTY; without even the implied warranty of
400 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
401 GNU General Public License for more details.
403 You should have received a copy of the GNU General Public License
404 along with this program; if not, write to the Free Software
405 Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
409 Also add information on how to contact you by electronic and paper mail.
413 If the program is interactive, make it output a short notice like this
414 when it starts in an interactive mode:
419 Gnomovision version 69, Copyright (C) 19<VAR>yy</VAR> <VAR>name of author</VAR>
420 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
422 This is free software, and you are welcome to redistribute it
423 under certain conditions; type `show c' for details.
427 The hypothetical commands <SAMP>`show w'</SAMP> and <SAMP>`show c'</SAMP> should show
428 the appropriate parts of the General Public License. Of course, the
429 commands you use may be called something other than <SAMP>`show w'</SAMP> and
430 <SAMP>`show c'</SAMP>; they could even be mouse-clicks or menu items--whatever
435 You should also get your employer (if you work as a programmer) or your
436 school, if any, to sign a "copyright disclaimer" for the program, if
437 necessary. Here is a sample; alter the names:

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