12 Everyone is permitted to copy and distribute verbatim copies
13 of this license document, but changing it is not allowed.
14
15 Preamble
16
17 The licenses for most software are designed to take away your
18freedom to share and change it. By contrast, the GNU General Public
19License is intended to guarantee your freedom to share and change free
20software--to make sure the software is free for all its users. This
21General Public License applies to most of the Free Software
22Foundation's software and to any other program whose authors commit to
23using it. (Some other Free Software Foundation software is covered by
24the GNU Library General Public License instead.) You can apply it to
25your programs, too.
26
27 When we speak of free software, we are referring to freedom, not
28price. Our General Public Licenses are designed to make sure that you
29have the freedom to distribute copies of free software (and charge for
30this service if you wish), that you receive source code or can get it
31if you want it, that you can change the software or use pieces of it
32in new free programs; and that you know you can do these things.
33
34 To protect your rights, we need to make restrictions that forbid
35anyone to deny you these rights or to ask you to surrender the rights.
36These restrictions translate to certain responsibilities for you if you
37distribute copies of the software, or if you modify it.
38
39 For example, if you distribute copies of such a program, whether
40gratis or for a fee, you must give the recipients all the rights that
41you have. You must make sure that they, too, receive or can get the
42source code. And you must show them these terms so they know their
43rights.
44
45 We protect your rights with two steps: (1) copyright the software, and
46(2) offer you this license which gives you legal permission to copy,
47distribute and/or modify the software.
48
49 Also, for each author's protection and ours, we want to make certain
50that everyone understands that there is no warranty for this free
51software. If the software is modified by someone else and passed on, we
52want its recipients to know that what they have is not the original, so
53that any problems introduced by others will not reflect on the original
54authors' reputations.
55
56 Finally, any free program is threatened constantly by software
57patents. We wish to avoid the danger that redistributors of a free
58program will individually obtain patent licenses, in effect making the
59program proprietary. To prevent this, we have made it clear that any
60patent must be licensed for everyone's free use or not licensed at all.
61
62 The precise terms and conditions for copying, distribution and
63modification follow.
64
65 GNU GENERAL PUBLIC LICENSE
66 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
67
68 0. This License applies to any program or other work which contains
69a notice placed by the copyright holder saying it may be distributed
70under the terms of this General Public License. The "Program", below,
71refers to any such program or work, and a "work based on the Program"
72means either the Program or any derivative work under copyright law:
73that is to say, a work containing the Program or a portion of it,
74either verbatim or with modifications and/or translated into another
75language. (Hereinafter, translation is included without limitation in
76the term "modification".) Each licensee is addressed as "you".
77
78Activities other than copying, distribution and modification are not
79covered by this License; they are outside its scope. The act of
80running the Program is not restricted, and the output from the Program
81is covered only if its contents constitute a work based on the
82Program (independent of having been made by running the Program).
83Whether that is true depends on what the Program does.
84
85 1. You may copy and distribute verbatim copies of the Program's
86source code as you receive it, in any medium, provided that you
87conspicuously and appropriately publish on each copy an appropriate
88copyright notice and disclaimer of warranty; keep intact all the
89notices that refer to this License and to the absence of any warranty;
90and give any other recipients of the Program a copy of this License
91along with the Program.
92
93You may charge a fee for the physical act of transferring a copy, and
94you may at your option offer warranty protection in exchange for a fee.
95
96 2. You may modify your copy or copies of the Program or any portion
97of it, thus forming a work based on the Program, and copy and
98distribute such modifications or work under the terms of Section 1
99above, provided that you also meet all of these conditions:
100
101 a) You must cause the modified files to carry prominent notices
102 stating that you changed the files and the date of any change.
103
104 b) You must cause any work that you distribute or publish, that in
105 whole or in part contains or is derived from the Program or any
106 part thereof, to be licensed as a whole at no charge to all third
107 parties under the terms of this License.
108
109 c) If the modified program normally reads commands interactively
110 when run, you must cause it, when started running for such
111 interactive use in the most ordinary way, to print or display an
112 announcement including an appropriate copyright notice and a
113 notice that there is no warranty (or else, saying that you provide
114 a warranty) and that users may redistribute the program under
115 these conditions, and telling the user how to view a copy of this
116 License. (Exception: if the Program itself is interactive but
117 does not normally print such an announcement, your work based on
118 the Program is not required to print an announcement.)
119
120These requirements apply to the modified work as a whole. If
121identifiable sections of that work are not derived from the Program,
122and can be reasonably considered independent and separate works in
123themselves, then this License, and its terms, do not apply to those
124sections when you distribute them as separate works. But when you
125distribute the same sections as part of a whole which is a work based
126on the Program, the distribution of the whole must be on the terms of
127this License, whose permissions for other licensees extend to the
128entire whole, and thus to each and every part regardless of who wrote it.
129
130Thus, it is not the intent of this section to claim rights or contest
131your rights to work written entirely by you; rather, the intent is to
132exercise the right to control the distribution of derivative or
133collective works based on the Program.
134
135In addition, mere aggregation of another work not based on the Program
136with the Program (or with a work based on the Program) on a volume of
137a storage or distribution medium does not bring the other work under
138the scope of this License.
139
140 3. You may copy and distribute the Program (or a work based on it,
141under Section 2) in object code or executable form under the terms of
142Sections 1 and 2 above provided that you also do one of the following:
143
144 a) Accompany it with the complete corresponding machine-readable
145 source code, which must be distributed under the terms of Sections
146 1 and 2 above on a medium customarily used for software interchange; or,
147
148 b) Accompany it with a written offer, valid for at least three
149 years, to give any third party, for a charge no more than your
150 cost of physically performing source distribution, a complete
151 machine-readable copy of the corresponding source code, to be
152 distributed under the terms of Sections 1 and 2 above on a medium
153 customarily used for software interchange; or,
154
155 c) Accompany it with the information you received as to the offer
156 to distribute corresponding source code. (This alternative is
157 allowed only for noncommercial distribution and only if you
158 received the program in object code or executable form with such
159 an offer, in accord with Subsection b above.)
160
161The source code for a work means the preferred form of the work for
162making modifications to it. For an executable work, complete source
163code means all the source code for all modules it contains, plus any
164associated interface definition files, plus the scripts used to
165control compilation and installation of the executable. However, as a
166special exception, the source code distributed need not include
167anything that is normally distributed (in either source or binary
168form) with the major components (compiler, kernel, and so on) of the
169operating system on which the executable runs, unless that component
170itself accompanies the executable.
171
172If distribution of executable or object code is made by offering
173access to copy from a designated place, then offering equivalent
174access to copy the source code from the same place counts as
175distribution of the source code, even though third parties are not
176compelled to copy the source along with the object code.
177
178 4. You may not copy, modify, sublicense, or distribute the Program
179except as expressly provided under this License. Any attempt
180otherwise to copy, modify, sublicense or distribute the Program is
181void, and will automatically terminate your rights under this License.
182However, parties who have received copies, or rights, from you under
183this License will not have their licenses terminated so long as such
184parties remain in full compliance.
185
186 5. You are not required to accept this License, since you have not
187signed it. However, nothing else grants you permission to modify or
188distribute the Program or its derivative works. These actions are
189prohibited by law if you do not accept this License. Therefore, by
190modifying or distributing the Program (or any work based on the
191Program), you indicate your acceptance of this License to do so, and
192all its terms and conditions for copying, distributing or modifying
193the Program or works based on it.
194
195 6. Each time you redistribute the Program (or any work based on the
196Program), the recipient automatically receives a license from the
197original licensor to copy, distribute or modify the Program subject to
198these terms and conditions. You may not impose any further
199restrictions on the recipients' exercise of the rights granted herein.
200You are not responsible for enforcing compliance by third parties to
201this License.
202
203 7. If, as a consequence of a court judgment or allegation of patent
204infringement or for any other reason (not limited to patent issues),
205conditions are imposed on you (whether by court order, agreement or
206otherwise) that contradict the conditions of this License, they do not
207excuse you from the conditions of this License. If you cannot
208distribute so as to satisfy simultaneously your obligations under this
209License and any other pertinent obligations, then as a consequence you
210may not distribute the Program at all. For example, if a patent
211license would not permit royalty-free redistribution of the Program by
212all those who receive copies directly or indirectly through you, then
213the only way you could satisfy both it and this License would be to
214refrain entirely from distribution of the Program.
215
216If any portion of this section is held invalid or unenforceable under
217any particular circumstance, the balance of the section is intended to
218apply and the section as a whole is intended to apply in other
219circumstances.
220
221It is not the purpose of this section to induce you to infringe any
222patents or other property right claims or to contest validity of any
223such claims; this section has the sole purpose of protecting the
224integrity of the free software distribution system, which is
225implemented by public license practices. Many people have made
226generous contributions to the wide range of software distributed
227through that system in reliance on consistent application of that
228system; it is up to the author/donor to decide if he or she is willing
229to distribute software through any other system and a licensee cannot
230impose that choice.
231
232This section is intended to make thoroughly clear what is believed to
233be a consequence of the rest of this License.
234
235 8. If the distribution and/or use of the Program is restricted in
236certain countries either by patents or by copyrighted interfaces, the
237original copyright holder who places the Program under this License
238may add an explicit geographical distribution limitation excluding
239those countries, so that distribution is permitted only in or among
240countries not thus excluded. In such case, this License incorporates
241the limitation as if written in the body of this License.
242
243 9. The Free Software Foundation may publish revised and/or new versions
244of the General Public License from time to time. Such new versions will
245be similar in spirit to the present version, but may differ in detail to
246address new problems or concerns.
247
248Each version is given a distinguishing version number. If the Program
249specifies a version number of this License which applies to it and "any
250later version", you have the option of following the terms and conditions
251either of that version or of any later version published by the Free
252Software Foundation. If the Program does not specify a version number of
253this License, you may choose any version ever published by the Free Software
254Foundation.
255
256 10. If you wish to incorporate parts of the Program into other free
257programs whose distribution conditions are different, write to the author
258to ask for permission. For software which is copyrighted by the Free
259Software Foundation, write to the Free Software Foundation; we sometimes
260make exceptions for this. Our decision will be guided by the two goals
261of preserving the free status of all derivatives of our free software and
262of promoting the sharing and reuse of software generally.
263
264 NO WARRANTY
265
266 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
267FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
268OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
269PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
270OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
271MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
272TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
273PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
274REPAIR OR CORRECTION.
275
276 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
277WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
278REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
279INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
280OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
281TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
282YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
283PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
284POSSIBILITY OF SUCH DAMAGES.
285
286 END OF TERMS AND CONDITIONS
287
288 How to Apply These Terms to Your New Programs
289
290 If you develop a new program, and you want it to be of the greatest
291possible use to the public, the best way to achieve this is to make it
292free software which everyone can redistribute and change under these terms.
293
294 To do so, attach the following notices to the program. It is safest
295to attach them to the start of each source file to most effectively
296convey the exclusion of warranty; and each file should have at least
297the "copyright" line and a pointer to where the full notice is found.
298
299 <one line to give the program's name and a brief idea of what it does.>
300 Copyright (C) <year> <name of author>
301
302 This program is free software; you can redistribute it and/or modify
303 it under the terms of the GNU General Public License as published by
304 the Free Software Foundation; either version 2 of the License, or
305 (at your option) any later version.
306
307 This program is distributed in the hope that it will be useful,
308 but WITHOUT ANY WARRANTY; without even the implied warranty of
309 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
310 GNU General Public License for more details.
311
312 You should have received a copy of the GNU General Public License
313 along with this program; if not, write to the Free Software
314 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
315
316
317Also add information on how to contact you by electronic and paper mail.
318
319If the program is interactive, make it output a short notice like this
320when it starts in an interactive mode:
321
322 Gnomovision version 69, Copyright (C) year name of author
323 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
324 This is free software, and you are welcome to redistribute it
325 under certain conditions; type `show c' for details.
326
327The hypothetical commands `show w' and `show c' should show the appropriate
328parts of the General Public License. Of course, the commands you use may
329be called something other than `show w' and `show c'; they could even be
330mouse-clicks or menu items--whatever suits your program.
331
332You should also get your employer (if you work as a programmer) or your
333school, if any, to sign a "copyright disclaimer" for the program, if
334necessary. Here is a sample; alter the names:
335
336 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
337 `Gnomovision' (which makes passes at compilers) written by James Hacker.
338
339 <signature of Ty Coon>, 1 April 1989
340 Ty Coon, President of Vice
341
342This General Public License does not permit incorporating your program into
343proprietary programs. If your program is a subroutine library, you may
344consider it more useful to permit linking proprietary applications with the
345library. If this is what you want to do, use the GNU Library General
346Public License instead of this License.
