31 GNU GENERAL PUBLIC LICENSE
34 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
35 51 Franklin Street, Fifth Floor, Boston, MA 02111-1307, USA.
36 Everyone is permitted to copy and distribute verbatim copies
37 of this license document, but changing it is not allowed.
41 The licenses for most software are designed to take away your
42 freedom to share and change it. By contrast, the GNU General Public
43 License is intended to guarantee your freedom to share and change free
44 software--to make sure the software is free for all its users. This
45 General Public License applies to most of the Free Software
46 Foundation's software and to any other program whose authors commit to
47 using it. (Some other Free Software Foundation software is covered by
48 the GNU Library General Public License instead.) You can apply it to
51 When we speak of free software, we are referring to freedom, not
52 price. Our General Public Licenses are designed to make sure that you
53 have the freedom to distribute copies of free software (and charge for
54 this service if you wish), that you receive source code or can get it
55 if you want it, that you can change the software or use pieces of it
56 in new free programs; and that you know you can do these things.
58 To protect your rights, we need to make restrictions that forbid
59 anyone to deny you these rights or to ask you to surrender the rights.
60 These restrictions translate to certain responsibilities for you if you
61 distribute copies of the software, or if you modify it.
63 For example, if you distribute copies of such a program, whether
64 gratis or for a fee, you must give the recipients all the rights that
65 you have. You must make sure that they, too, receive or can get the
66 source code. And you must show them these terms so they know their
69 We protect your rights with two steps: (1) copyright the software, and
70 (2) offer you this license which gives you legal permission to copy,
71 distribute and/or modify the software.
73 Also, for each author's protection and ours, we want to make certain
74 that everyone understands that there is no warranty for this free
75 software. If the software is modified by someone else and passed on, we
76 want its recipients to know that what they have is not the original, so
77 that any problems introduced by others will not reflect on the original
80 Finally, any free program is threatened constantly by software
81 patents. We wish to avoid the danger that redistributors of a free
82 program will individually obtain patent licenses, in effect making the
83 program proprietary. To prevent this, we have made it clear that any
84 patent must be licensed for everyone's free use or not licensed at all.
86 The precise terms and conditions for copying, distribution and
89 GNU GENERAL PUBLIC LICENSE
90 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
92 0. This License applies to any program or other work which contains
93 a notice placed by the copyright holder saying it may be distributed
94 under the terms of this General Public License. The "Program", below,
95 refers to any such program or work, and a "work based on the Program"
96 means either the Program or any derivative work under copyright law:
97 that is to say, a work containing the Program or a portion of it,
98 either verbatim or with modifications and/or translated into another
99 language. (Hereinafter, translation is included without limitation in
100 the term "modification".) Each licensee is addressed as "you".
102 Activities other than copying, distribution and modification are not
103 covered by this License; they are outside its scope. The act of
104 running the Program is not restricted, and the output from the Program
105 is covered only if its contents constitute a work based on the
106 Program (independent of having been made by running the Program).
107 Whether that is true depends on what the Program does.
109 1. You may copy and distribute verbatim copies of the Program's
110 source code as you receive it, in any medium, provided that you
111 conspicuously and appropriately publish on each copy an appropriate
112 copyright notice and disclaimer of warranty; keep intact all the
113 notices that refer to this License and to the absence of any warranty;
114 and give any other recipients of the Program a copy of this License
115 along with the Program.
117 You may charge a fee for the physical act of transferring a copy, and
118 you may at your option offer warranty protection in exchange for a fee.
120 2. You may modify your copy or copies of the Program or any portion
121 of it, thus forming a work based on the Program, and copy and
122 distribute such modifications or work under the terms of Section 1
123 above, provided that you also meet all of these conditions:
125 a) You must cause the modified files to carry prominent notices
126 stating that you changed the files and the date of any change.
128 b) You must cause any work that you distribute or publish, that in
129 whole or in part contains or is derived from the Program or any
130 part thereof, to be licensed as a whole at no charge to all third
131 parties under the terms of this License.
133 c) If the modified program normally reads commands interactively
134 when run, you must cause it, when started running for such
135 interactive use in the most ordinary way, to print or display an
136 announcement including an appropriate copyright notice and a
137 notice that there is no warranty (or else, saying that you provide
138 a warranty) and that users may redistribute the program under
139 these conditions, and telling the user how to view a copy of this
140 License. (Exception: if the Program itself is interactive but
141 does not normally print such an announcement, your work based on
142 the Program is not required to print an announcement.)
144 These requirements apply to the modified work as a whole. If
145 identifiable sections of that work are not derived from the Program,
146 and can be reasonably considered independent and separate works in
147 themselves, then this License, and its terms, do not apply to those
148 sections when you distribute them as separate works. But when you
149 distribute the same sections as part of a whole which is a work based
150 on the Program, the distribution of the whole must be on the terms of
151 this License, whose permissions for other licensees extend to the
152 entire whole, and thus to each and every part regardless of who wrote it.
154 Thus, it is not the intent of this section to claim rights or contest
155 your rights to work written entirely by you; rather, the intent is to
156 exercise the right to control the distribution of derivative or
157 collective works based on the Program.
159 In addition, mere aggregation of another work not based on the Program
160 with the Program (or with a work based on the Program) on a volume of
161 a storage or distribution medium does not bring the other work under
162 the scope of this License.
164 3. You may copy and distribute the Program (or a work based on it,
165 under Section 2) in object code or executable form under the terms of
166 Sections 1 and 2 above provided that you also do one of the following:
168 a) Accompany it with the complete corresponding machine-readable
169 source code, which must be distributed under the terms of Sections
170 1 and 2 above on a medium customarily used for software interchange; or,
172 b) Accompany it with a written offer, valid for at least three
173 years, to give any third party, for a charge no more than your
174 cost of physically performing source distribution, a complete
175 machine-readable copy of the corresponding source code, to be
176 distributed under the terms of Sections 1 and 2 above on a medium
177 customarily used for software interchange; or,
179 c) Accompany it with the information you received as to the offer
180 to distribute corresponding source code. (This alternative is
181 allowed only for noncommercial distribution and only if you
182 received the program in object code or executable form with such
183 an offer, in accord with Subsection b above.)
185 The source code for a work means the preferred form of the work for
186 making modifications to it. For an executable work, complete source
187 code means all the source code for all modules it contains, plus any
188 associated interface definition files, plus the scripts used to
189 control compilation and installation of the executable. However, as a
190 special exception, the source code distributed need not include
191 anything that is normally distributed (in either source or binary
192 form) with the major components (compiler, kernel, and so on) of the
193 operating system on which the executable runs, unless that component
194 itself accompanies the executable.
196 If distribution of executable or object code is made by offering
197 access to copy from a designated place, then offering equivalent
198 access to copy the source code from the same place counts as
199 distribution of the source code, even though third parties are not
200 compelled to copy the source along with the object code.
202 4. You may not copy, modify, sublicense, or distribute the Program
203 except as expressly provided under this License. Any attempt
204 otherwise to copy, modify, sublicense or distribute the Program is
205 void, and will automatically terminate your rights under this License.
206 However, parties who have received copies, or rights, from you under
207 this License will not have their licenses terminated so long as such
208 parties remain in full compliance.
210 5. You are not required to accept this License, since you have not
211 signed it. However, nothing else grants you permission to modify or
212 distribute the Program or its derivative works. These actions are
213 prohibited by law if you do not accept this License. Therefore, by
214 modifying or distributing the Program (or any work based on the
215 Program), you indicate your acceptance of this License to do so, and
216 all its terms and conditions for copying, distributing or modifying
217 the Program or works based on it.
219 6. Each time you redistribute the Program (or any work based on the
220 Program), the recipient automatically receives a license from the
221 original licensor to copy, distribute or modify the Program subject to
222 these terms and conditions. You may not impose any further
223 restrictions on the recipients' exercise of the rights granted herein.
224 You are not responsible for enforcing compliance by third parties to
227 7. If, as a consequence of a court judgment or allegation of patent
228 infringement or for any other reason (not limited to patent issues),
229 conditions are imposed on you (whether by court order, agreement or
230 otherwise) that contradict the conditions of this License, they do not
231 excuse you from the conditions of this License. If you cannot
232 distribute so as to satisfy simultaneously your obligations under this
233 License and any other pertinent obligations, then as a consequence you
234 may not distribute the Program at all. For example, if a patent
235 license would not permit royalty-free redistribution of the Program by
236 all those who receive copies directly or indirectly through you, then
237 the only way you could satisfy both it and this License would be to
238 refrain entirely from distribution of the Program.
240 If any portion of this section is held invalid or unenforceable under
241 any particular circumstance, the balance of the section is intended to
242 apply and the section as a whole is intended to apply in other
245 It is not the purpose of this section to induce you to infringe any
246 patents or other property right claims or to contest validity of any
247 such claims; this section has the sole purpose of protecting the
248 integrity of the free software distribution system, which is
249 implemented by public license practices. Many people have made
250 generous contributions to the wide range of software distributed
251 through that system in reliance on consistent application of that
252 system; it is up to the author/donor to decide if he or she is willing
253 to distribute software through any other system and a licensee cannot
256 This section is intended to make thoroughly clear what is believed to
257 be a consequence of the rest of this License.
259 8. If the distribution and/or use of the Program is restricted in
260 certain countries either by patents or by copyrighted interfaces, the
261 original copyright holder who places the Program under this License
262 may add an explicit geographical distribution limitation excluding
263 those countries, so that distribution is permitted only in or among
264 countries not thus excluded. In such case, this License incorporates
265 the limitation as if written in the body of this License.
267 9. The Free Software Foundation may publish revised and/or new versions
268 of the General Public License from time to time. Such new versions will
269 be similar in spirit to the present version, but may differ in detail to
270 address new problems or concerns.
272 Each version is given a distinguishing version number. If the Program
273 specifies a version number of this License which applies to it and "any
274 later version", you have the option of following the terms and conditions
275 either of that version or of any later version published by the Free
276 Software Foundation. If the Program does not specify a version number of
277 this License, you may choose any version ever published by the Free Software
280 10. If you wish to incorporate parts of the Program into other free
281 programs whose distribution conditions are different, write to the author
282 to ask for permission. For software which is copyrighted by the Free
283 Software Foundation, write to the Free Software Foundation; we sometimes
284 make exceptions for this. Our decision will be guided by the two goals
285 of preserving the free status of all derivatives of our free software and
286 of promoting the sharing and reuse of software generally.
290 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
291 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
292 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
293 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
294 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
295 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
296 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
297 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
298 REPAIR OR CORRECTION.
300 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
301 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
302 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
303 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
304 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
305 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
306 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
307 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
308 POSSIBILITY OF SUCH DAMAGES.
310 END OF TERMS AND CONDITIONS
312 Appendix: How to Apply These Terms to Your New Programs
314 If you develop a new program, and you want it to be of the greatest
315 possible use to the public, the best way to achieve this is to make it
316 free software which everyone can redistribute and change under these terms.
318 To do so, attach the following notices to the program. It is safest
319 to attach them to the start of each source file to most effectively
320 convey the exclusion of warranty; and each file should have at least
321 the "copyright" line and a pointer to where the full notice is found.
323 <one line to give the program's name and a brief idea of what it does.>
324 Copyright (C) 19yy <name of author>
326 This program is free software; you can redistribute it and/or modify
327 it under the terms of the GNU General Public License as published by
328 the Free Software Foundation; either version 2 of the License, or
329 (at your option) any later version.
331 This program is distributed in the hope that it will be useful,
332 but WITHOUT ANY WARRANTY; without even the implied warranty of
333 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
334 GNU General Public License for more details.
336 You should have received a copy of the GNU General Public License
337 along with this program; if not, write to the Free Software Foundation,
338 Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02111-1307, USA.
340 Also add information on how to contact you by electronic and paper mail.
342 If the program is interactive, make it output a short notice like this
343 when it starts in an interactive mode:
345 Gnomovision version 69, Copyright (C) 19yy name of author
346 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
347 This is free software, and you are welcome to redistribute it
348 under certain conditions; type `show c' for details.
350 The hypothetical commands `show w' and `show c' should show the appropriate
351 parts of the General Public License. Of course, the commands you use may
352 be called something other than `show w' and `show c'; they could even be
353 mouse-clicks or menu items--whatever suits your program.
355 You should also get your employer (if you work as a programmer) or your
356 school, if any, to sign a "copyright disclaimer" for the program, if
357 necessary. Here is a sample; alter the names:
359 Yoyodyne, Inc., hereby disclaims all copyright interest in the program

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