70 GNU GENERAL PUBLIC LICENSE
73 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
74 59 Temple Place, Suite 330, Boston, MA 02111, USA
75 Everyone is permitted to copy and distribute verbatim copies
76 of this license document, but changing it is not allowed.
80 The licenses for most software are designed to take away your
81 freedom to share and change it. By contrast, the GNU General Public
82 License is intended to guarantee your freedom to share and change free
83 software--to make sure the software is free for all its users. This
84 General Public License applies to most of the Free Software
85 Foundation's software and to any other program whose authors commit to
86 using it. (Some other Free Software Foundation software is covered by
87 the GNU Library General Public License instead.) You can apply it to
90 When we speak of free software, we are referring to freedom, not
91 price. Our General Public Licenses are designed to make sure that you
92 have the freedom to distribute copies of free software (and charge for
93 this service if you wish), that you receive source code or can get it
94 if you want it, that you can change the software or use pieces of it
95 in new free programs; and that you know you can do these things.
97 To protect your rights, we need to make restrictions that forbid
98 anyone to deny you these rights or to ask you to surrender the rights.
99 These restrictions translate to certain responsibilities for you if you
100 distribute copies of the software, or if you modify it.
102 For example, if you distribute copies of such a program, whether
103 gratis or for a fee, you must give the recipients all the rights that
104 you have. You must make sure that they, too, receive or can get the
105 source code. And you must show them these terms so they know their
108 We protect your rights with two steps: (1) copyright the software, and
109 (2) offer you this license which gives you legal permission to copy,
110 distribute and/or modify the software.
112 Also, for each author's protection and ours, we want to make certain
113 that everyone understands that there is no warranty for this free
114 software. If the software is modified by someone else and passed on, we
115 want its recipients to know that what they have is not the original, so
116 that any problems introduced by others will not reflect on the original
117 authors' reputations.
119 Finally, any free program is threatened constantly by software
120 patents. We wish to avoid the danger that redistributors of a free
121 program will individually obtain patent licenses, in effect making the
122 program proprietary. To prevent this, we have made it clear that any
123 patent must be licensed for everyone's free use or not licensed at all.
125 The precise terms and conditions for copying, distribution and
128 GNU GENERAL PUBLIC LICENSE
129 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
131 0. This License applies to any program or other work which contains
132 a notice placed by the copyright holder saying it may be distributed
133 under the terms of this General Public License. The "Program", below,
134 refers to any such program or work, and a "work based on the Program"
135 means either the Program or any derivative work under copyright law:
136 that is to say, a work containing the Program or a portion of it,
137 either verbatim or with modifications and/or translated into another
138 language. (Hereinafter, translation is included without limitation in
139 the term "modification".) Each licensee is addressed as "you".
141 Activities other than copying, distribution and modification are not
142 covered by this License; they are outside its scope. The act of
143 running the Program is not restricted, and the output from the Program
144 is covered only if its contents constitute a work based on the
145 Program (independent of having been made by running the Program).
146 Whether that is true depends on what the Program does.
148 1. You may copy and distribute verbatim copies of the Program's
149 source code as you receive it, in any medium, provided that you
150 conspicuously and appropriately publish on each copy an appropriate
151 copyright notice and disclaimer of warranty; keep intact all the
152 notices that refer to this License and to the absence of any warranty;
153 and give any other recipients of the Program a copy of this License
154 along with the Program.
156 You may charge a fee for the physical act of transferring a copy, and
157 you may at your option offer warranty protection in exchange for a fee.
159 2. You may modify your copy or copies of the Program or any portion
160 of it, thus forming a work based on the Program, and copy and
161 distribute such modifications or work under the terms of Section 1
162 above, provided that you also meet all of these conditions:
164 a) You must cause the modified files to carry prominent notices
165 stating that you changed the files and the date of any change.
167 b) You must cause any work that you distribute or publish, that in
168 whole or in part contains or is derived from the Program or any
169 part thereof, to be licensed as a whole at no charge to all third
170 parties under the terms of this License.
172 c) If the modified program normally reads commands interactively
173 when run, you must cause it, when started running for such
174 interactive use in the most ordinary way, to print or display an
175 announcement including an appropriate copyright notice and a
176 notice that there is no warranty (or else, saying that you provide
177 a warranty) and that users may redistribute the program under
178 these conditions, and telling the user how to view a copy of this
179 License. (Exception: if the Program itself is interactive but
180 does not normally print such an announcement, your work based on
181 the Program is not required to print an announcement.)
183 These requirements apply to the modified work as a whole. If
184 identifiable sections of that work are not derived from the Program,
185 and can be reasonably considered independent and separate works in
186 themselves, then this License, and its terms, do not apply to those
187 sections when you distribute them as separate works. But when you
188 distribute the same sections as part of a whole which is a work based
189 on the Program, the distribution of the whole must be on the terms of
190 this License, whose permissions for other licensees extend to the
191 entire whole, and thus to each and every part regardless of who wrote it.
193 Thus, it is not the intent of this section to claim rights or contest
194 your rights to work written entirely by you; rather, the intent is to
195 exercise the right to control the distribution of derivative or
196 collective works based on the Program.
198 In addition, mere aggregation of another work not based on the Program
199 with the Program (or with a work based on the Program) on a volume of
200 a storage or distribution medium does not bring the other work under
201 the scope of this License.
203 3. You may copy and distribute the Program (or a work based on it,
204 under Section 2) in object code or executable form under the terms of
205 Sections 1 and 2 above provided that you also do one of the following:
207 a) Accompany it with the complete corresponding machine-readable
208 source code, which must be distributed under the terms of Sections
209 1 and 2 above on a medium customarily used for software interchange; or,
211 b) Accompany it with a written offer, valid for at least three
212 years, to give any third party, for a charge no more than your
213 cost of physically performing source distribution, a complete
214 machine-readable copy of the corresponding source code, to be
215 distributed under the terms of Sections 1 and 2 above on a medium
216 customarily used for software interchange; or,
218 c) Accompany it with the information you received as to the offer
219 to distribute corresponding source code. (This alternative is
220 allowed only for noncommercial distribution and only if you
221 received the program in object code or executable form with such
222 an offer, in accord with Subsection b above.)
224 The source code for a work means the preferred form of the work for
225 making modifications to it. For an executable work, complete source
226 code means all the source code for all modules it contains, plus any
227 associated interface definition files, plus the scripts used to
228 control compilation and installation of the executable. However, as a
229 special exception, the source code distributed need not include
230 anything that is normally distributed (in either source or binary
231 form) with the major components (compiler, kernel, and so on) of the
232 operating system on which the executable runs, unless that component
233 itself accompanies the executable.
235 If distribution of executable or object code is made by offering
236 access to copy from a designated place, then offering equivalent
237 access to copy the source code from the same place counts as
238 distribution of the source code, even though third parties are not
239 compelled to copy the source along with the object code.
241 4. 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.
249 5. You are not required to accept this License, since you have not
250 signed it. However, nothing else grants you permission to modify or
251 distribute the Program or its derivative works. These actions are
252 prohibited by law if you do not accept this License. Therefore, by
253 modifying or distributing the Program (or any work based on the
254 Program), you indicate your acceptance of this License to do so, and
255 all its terms and conditions for copying, distributing or modifying
256 the Program or works based on it.
258 6. Each time you redistribute the Program (or any work based on the
259 Program), the recipient automatically receives a license from the
260 original licensor to copy, distribute or modify the Program subject to
261 these terms and conditions. You may not impose any further
262 restrictions on the recipients' exercise of the rights granted herein.
263 You are not responsible for enforcing compliance by third parties to
266 7. If, as a consequence of a court judgment or allegation of patent
267 infringement or for any other reason (not limited to patent issues),
268 conditions are imposed on you (whether by court order, agreement or
269 otherwise) that contradict the conditions of this License, they do not
270 excuse you from the conditions of this License. If you cannot
271 distribute so as to satisfy simultaneously your obligations under this
272 License and any other pertinent obligations, then as a consequence you
273 may not distribute the Program at all. For example, if a patent
274 license would not permit royalty-free redistribution of the Program by
275 all those who receive copies directly or indirectly through you, then
276 the only way you could satisfy both it and this License would be to
277 refrain entirely from distribution of the Program.
279 If any portion of this section is held invalid or unenforceable under
280 any particular circumstance, the balance of the section is intended to
281 apply and the section as a whole is intended to apply in other
284 It is not the purpose of this section to induce you to infringe any
285 patents or other property right claims or to contest validity of any
286 such claims; this section has the sole purpose of protecting the
287 integrity of the free software distribution system, which is
288 implemented by public license practices. Many people have made
289 generous contributions to the wide range of software distributed
290 through that system in reliance on consistent application of that
291 system; it is up to the author/donor to decide if he or she is willing
292 to distribute software through any other system and a licensee cannot
295 This section is intended to make thoroughly clear what is believed to
296 be a consequence of the rest of this License.
298 8. If the distribution and/or use of the Program is restricted in
299 certain countries either by patents or by copyrighted interfaces, the
300 original copyright holder who places the Program under this License
301 may add an explicit geographical distribution limitation excluding
302 those countries, so that distribution is permitted only in or among
303 countries not thus excluded. In such case, this License incorporates
304 the limitation as if written in the body of this License.
306 9. The Free Software Foundation may publish revised and/or new versions
307 of the General Public License from time to time. Such new versions will
308 be similar in spirit to the present version, but may differ in detail to
309 address new problems or concerns.
311 Each version is given a distinguishing version number. If the Program
312 specifies a version number of this License which applies to it and "any
313 later version", you have the option of following the terms and conditions
314 either of that version or of any later version published by the Free
315 Software Foundation. If the Program does not specify a version number of
316 this License, you may choose any version ever published by the Free Software
319 10. If you wish to incorporate parts of the Program into other free
320 programs whose distribution conditions are different, write to the author
321 to ask for permission. For software which is copyrighted by the Free
322 Software Foundation, write to the Free Software Foundation; we sometimes
323 make exceptions for this. Our decision will be guided by the two goals
324 of preserving the free status of all derivatives of our free software and
325 of promoting the sharing and reuse of software generally.
329 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
330 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
331 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
332 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
333 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
334 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
335 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
336 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
337 REPAIR OR CORRECTION.
339 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
340 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
341 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
342 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
343 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
344 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
345 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
346 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
347 POSSIBILITY OF SUCH DAMAGES.
349 END OF TERMS AND CONDITIONS
351 Appendix: How to Apply These Terms to Your New Programs
353 If you develop a new program, and you want it to be of the greatest
354 possible use to the public, the best way to achieve this is to make it
355 free software which everyone can redistribute and change under these terms.
357 To do so, attach the following notices to the program. It is safest
358 to attach them to the start of each source file to most effectively
359 convey the exclusion of warranty; and each file should have at least
360 the "copyright" line and a pointer to where the full notice is found.
362 <one line to give the program's name and a brief idea of what it does.>

366 it under the terms of the GNU General Public License as published by
367 the Free Software Foundation; either version 2 of the License, or
368 (at your option) any later version.
370 This program is distributed in the hope that it will be useful,
371 but WITHOUT ANY WARRANTY; without even the implied warranty of
372 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
373 GNU General Public License for more details.

376 along with this program; if not, write to the Free Software
377 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111, USA.
379 Also add information on how to contact you by electronic and paper mail.
381 If the program is interactive, make it output a short notice like this
382 when it starts in an interactive mode:
384 Gnomovision version 69, Copyright (C) 19yy name of author
385 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
386 This is free software, and you are welcome to redistribute it
387 under certain conditions; type `show c' for details.
389 The hypothetical commands `show w' and `show c' should show the appropriate
390 parts of the General Public License. Of course, the commands you use may
391 be called something other than `show w' and `show c'; they could even be
392 mouse-clicks or menu items--whatever suits your program.
394 You should also get your employer (if you work as a programmer) or your
395 school, if any, to sign a "copyright disclaimer" for the program, if
396 necessary. Here is a sample; alter the names:

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