58 GNU GENERAL PUBLIC LICENSE
61 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
62 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
63 Everyone is permitted to copy and distribute verbatim copies
64 of this license document, but changing it is not allowed.
68 The licenses for most software are designed to take away your
69 freedom to share and change it. By contrast, the GNU General Public
70 License is intended to guarantee your freedom to share and change free
71 software--to make sure the software is free for all its users. This
72 General Public License applies to most of the Free Software
73 Foundation's software and to any other program whose authors commit to
74 using it. (Some other Free Software Foundation software is covered by
75 the GNU Library General Public License instead.) You can apply it to
78 When we speak of free software, we are referring to freedom, not
79 price. Our General Public Licenses are designed to make sure that you
80 have the freedom to distribute copies of free software (and charge for
81 this service if you wish), that you receive source code or can get it
82 if you want it, that you can change the software or use pieces of it
83 in new free programs; and that you know you can do these things.
85 To protect your rights, we need to make restrictions that forbid
86 anyone to deny you these rights or to ask you to surrender the rights.
87 These restrictions translate to certain responsibilities for you if you
88 distribute copies of the software, or if you modify it.
90 For example, if you distribute copies of such a program, whether
91 gratis or for a fee, you must give the recipients all the rights that
92 you have. You must make sure that they, too, receive or can get the
93 source code. And you must show them these terms so they know their
96 We protect your rights with two steps: (1) copyright the software, and
97 (2) offer you this license which gives you legal permission to copy,
98 distribute and/or modify the software.
100 Also, for each author's protection and ours, we want to make certain
101 that everyone understands that there is no warranty for this free
102 software. If the software is modified by someone else and passed on, we
103 want its recipients to know that what they have is not the original, so
104 that any problems introduced by others will not reflect on the original
105 authors' reputations.
107 Finally, any free program is threatened constantly by software
108 patents. We wish to avoid the danger that redistributors of a free
109 program will individually obtain patent licenses, in effect making the
110 program proprietary. To prevent this, we have made it clear that any
111 patent must be licensed for everyone's free use or not licensed at all.
113 The precise terms and conditions for copying, distribution and
116 GNU GENERAL PUBLIC LICENSE
117 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
119 0. This License applies to any program or other work which contains
120 a notice placed by the copyright holder saying it may be distributed
121 under the terms of this General Public License. The "Program", below,
122 refers to any such program or work, and a "work based on the Program"
123 means either the Program or any derivative work under copyright law:
124 that is to say, a work containing the Program or a portion of it,
125 either verbatim or with modifications and/or translated into another
126 language. (Hereinafter, translation is included without limitation in
127 the term "modification".) Each licensee is addressed as "you".
129 Activities other than copying, distribution and modification are not
130 covered by this License; they are outside its scope. The act of
131 running the Program is not restricted, and the output from the Program
132 is covered only if its contents constitute a work based on the
133 Program (independent of having been made by running the Program).
134 Whether that is true depends on what the Program does.
136 1. You may copy and distribute verbatim copies of the Program's
137 source code as you receive it, in any medium, provided that you
138 conspicuously and appropriately publish on each copy an appropriate
139 copyright notice and disclaimer of warranty; keep intact all the
140 notices that refer to this License and to the absence of any warranty;
141 and give any other recipients of the Program a copy of this License
142 along with the Program.
144 You may charge a fee for the physical act of transferring a copy, and
145 you may at your option offer warranty protection in exchange for a fee.
147 2. You may modify your copy or copies of the Program or any portion
148 of it, thus forming a work based on the Program, and copy and
149 distribute such modifications or work under the terms of Section 1
150 above, provided that you also meet all of these conditions:
152 a) You must cause the modified files to carry prominent notices
153 stating that you changed the files and the date of any change.
155 b) You must cause any work that you distribute or publish, that in
156 whole or in part contains or is derived from the Program or any
157 part thereof, to be licensed as a whole at no charge to all third
158 parties under the terms of this License.
160 c) If the modified program normally reads commands interactively
161 when run, you must cause it, when started running for such
162 interactive use in the most ordinary way, to print or display an
163 announcement including an appropriate copyright notice and a
164 notice that there is no warranty (or else, saying that you provide
165 a warranty) and that users may redistribute the program under
166 these conditions, and telling the user how to view a copy of this
167 License. (Exception: if the Program itself is interactive but
168 does not normally print such an announcement, your work based on
169 the Program is not required to print an announcement.)
171 These requirements apply to the modified work as a whole. If
172 identifiable sections of that work are not derived from the Program,
173 and can be reasonably considered independent and separate works in
174 themselves, then this License, and its terms, do not apply to those
175 sections when you distribute them as separate works. But when you
176 distribute the same sections as part of a whole which is a work based
177 on the Program, the distribution of the whole must be on the terms of
178 this License, whose permissions for other licensees extend to the
179 entire whole, and thus to each and every part regardless of who wrote it.
181 Thus, it is not the intent of this section to claim rights or contest
182 your rights to work written entirely by you; rather, the intent is to
183 exercise the right to control the distribution of derivative or
184 collective works based on the Program.
186 In addition, mere aggregation of another work not based on the Program
187 with the Program (or with a work based on the Program) on a volume of
188 a storage or distribution medium does not bring the other work under
189 the scope of this License.
191 3. You may copy and distribute the Program (or a work based on it,
192 under Section 2) in object code or executable form under the terms of
193 Sections 1 and 2 above provided that you also do one of the following:
195 a) Accompany it with the complete corresponding machine-readable
196 source code, which must be distributed under the terms of Sections
197 1 and 2 above on a medium customarily used for software interchange; or,
199 b) Accompany it with a written offer, valid for at least three
200 years, to give any third party, for a charge no more than your
201 cost of physically performing source distribution, a complete
202 machine-readable copy of the corresponding source code, to be
203 distributed under the terms of Sections 1 and 2 above on a medium
204 customarily used for software interchange; or,
206 c) Accompany it with the information you received as to the offer
207 to distribute corresponding source code. (This alternative is
208 allowed only for noncommercial distribution and only if you
209 received the program in object code or executable form with such
210 an offer, in accord with Subsection b above.)
212 The source code for a work means the preferred form of the work for
213 making modifications to it. For an executable work, complete source
214 code means all the source code for all modules it contains, plus any
215 associated interface definition files, plus the scripts used to
216 control compilation and installation of the executable. However, as a
217 special exception, the source code distributed need not include
218 anything that is normally distributed (in either source or binary
219 form) with the major components (compiler, kernel, and so on) of the
220 operating system on which the executable runs, unless that component
221 itself accompanies the executable.
223 If distribution of executable or object code is made by offering
224 access to copy from a designated place, then offering equivalent
225 access to copy the source code from the same place counts as
226 distribution of the source code, even though third parties are not
227 compelled to copy the source along with the object code.
229 4. You may not copy, modify, sublicense, or distribute the Program
230 except as expressly provided under this License. Any attempt
231 otherwise to copy, modify, sublicense or distribute the Program is
232 void, and will automatically terminate your rights under this License.
233 However, parties who have received copies, or rights, from you under
234 this License will not have their licenses terminated so long as such
235 parties remain in full compliance.
237 5. You are not required to accept this License, since you have not
238 signed it. However, nothing else grants you permission to modify or
239 distribute the Program or its derivative works. These actions are
240 prohibited by law if you do not accept this License. Therefore, by
241 modifying or distributing the Program (or any work based on the
242 Program), you indicate your acceptance of this License to do so, and
243 all its terms and conditions for copying, distributing or modifying
244 the Program or works based on it.
246 6. Each time you redistribute the Program (or any work based on the
247 Program), the recipient automatically receives a license from the
248 original licensor to copy, distribute or modify the Program subject to
249 these terms and conditions. You may not impose any further
250 restrictions on the recipients' exercise of the rights granted herein.
251 You are not responsible for enforcing compliance by third parties to
254 7. If, as a consequence of a court judgment or allegation of patent
255 infringement or for any other reason (not limited to patent issues),
256 conditions are imposed on you (whether by court order, agreement or
257 otherwise) that contradict the conditions of this License, they do not
258 excuse you from the conditions of this License. If you cannot
259 distribute so as to satisfy simultaneously your obligations under this
260 License and any other pertinent obligations, then as a consequence you
261 may not distribute the Program at all. For example, if a patent
262 license would not permit royalty-free redistribution of the Program by
263 all those who receive copies directly or indirectly through you, then
264 the only way you could satisfy both it and this License would be to
265 refrain entirely from distribution of the Program.
267 If any portion of this section is held invalid or unenforceable under
268 any particular circumstance, the balance of the section is intended to
269 apply and the section as a whole is intended to apply in other
272 It is not the purpose of this section to induce you to infringe any
273 patents or other property right claims or to contest validity of any
274 such claims; this section has the sole purpose of protecting the
275 integrity of the free software distribution system, which is
276 implemented by public license practices. Many people have made
277 generous contributions to the wide range of software distributed
278 through that system in reliance on consistent application of that
279 system; it is up to the author/donor to decide if he or she is willing
280 to distribute software through any other system and a licensee cannot
283 This section is intended to make thoroughly clear what is believed to
284 be a consequence of the rest of this License.
286 8. If the distribution and/or use of the Program is restricted in
287 certain countries either by patents or by copyrighted interfaces, the
288 original copyright holder who places the Program under this License
289 may add an explicit geographical distribution limitation excluding
290 those countries, so that distribution is permitted only in or among
291 countries not thus excluded. In such case, this License incorporates
292 the limitation as if written in the body of this License.
294 9. The Free Software Foundation may publish revised and/or new versions
295 of the General Public License from time to time. Such new versions will
296 be similar in spirit to the present version, but may differ in detail to
297 address new problems or concerns.
299 Each version is given a distinguishing version number. If the Program
300 specifies a version number of this License which applies to it and "any
301 later version", you have the option of following the terms and conditions
302 either of that version or of any later version published by the Free
303 Software Foundation. If the Program does not specify a version number of
304 this License, you may choose any version ever published by the Free Software
307 10. If you wish to incorporate parts of the Program into other free
308 programs whose distribution conditions are different, write to the author
309 to ask for permission. For software which is copyrighted by the Free
310 Software Foundation, write to the Free Software Foundation; we sometimes
311 make exceptions for this. Our decision will be guided by the two goals
312 of preserving the free status of all derivatives of our free software and
313 of promoting the sharing and reuse of software generally.
317 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
318 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
319 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
320 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
321 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
322 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
323 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
324 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
325 REPAIR OR CORRECTION.
327 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
328 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
329 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
330 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
331 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
332 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
333 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
334 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
335 POSSIBILITY OF SUCH DAMAGES.
337 END OF TERMS AND CONDITIONS
339 How to Apply These Terms to Your New Programs
341 If you develop a new program
, and you want it to be of the greatest
342 possible
use to the public
, the best way to achieve this is to make it
343 free software which everyone can redistribute
and change under these terms
.
345 To
do so
, attach the following notices to the program
. It is safest
346 to attach them to the start of
each source file to most effectively
347 convey the exclusion of warranty
; and each file should have at least
348 the
"copyright" line
and a pointer to where the full notice is found
.
350 <one line to give the program
's name and a brief idea of what it does.>
351 Copyright (C) <year> <name of author>
353 This program is free software; you can redistribute it and/or modify
354 it under the terms of the GNU General Public License as published by
355 the Free Software Foundation; either version 2 of the License, or
356 (at your option) any later version.
358 This program is distributed in the hope that it will be useful,
359 but WITHOUT ANY WARRANTY; without even the implied warranty of
360 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
361 GNU General Public License for more details.
363 You should have received a copy of the GNU General Public License
364 along with this program; if not, write to the Free Software
365 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
368 Also add information on how to contact you by electronic and paper mail.
370 If the program is interactive, make it output a short notice like this
371 when it starts in an interactive mode:
373 Gnomovision version 69, Copyright (C) year name of author
374 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
375 This is free software
, and you are welcome to redistribute it
376 under certain conditions
; type
`show c' for details.
378 The hypothetical commands `show w
' and `show c' should show the appropriate
379 parts of the General Public License
. Of course
, the commands you
use may
380 be called something other than
`show w' and `show c
'; they could even be
381 mouse-clicks or menu items--whatever suits your program.
383 You should also get your employer (if you work as a programmer) or your
384 school, if any, to sign a "copyright disclaimer" for the program, if
385 necessary. Here is a sample; alter the names:
387 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
388 `Gnomovision' (which makes passes at compilers
) written by James Hacker

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