12 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
13 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
14 Everyone is permitted to copy and distribute verbatim copies
15 of this license document, but changing it is not allowed.
16
17 Preamble
18
19 The licenses for most software are designed to take away your
20freedom to share and change it. By contrast, the GNU General Public
21License is intended to guarantee your freedom to share and change free
22software--to make sure the software is free for all its users. This
23General Public License applies to most of the Free Software
24Foundation's software and to any other program whose authors commit to
25using it. (Some other Free Software Foundation software is covered by
26the GNU Library General Public License instead.) You can apply it to
27your programs, too.
28
29 When we speak of free software, we are referring to freedom, not
30price. Our General Public Licenses are designed to make sure that you
31have the freedom to distribute copies of free software (and charge for
32this service if you wish), that you receive source code or can get it
33if you want it, that you can change the software or use pieces of it
34in new free programs; and that you know you can do these things.
35
36 To protect your rights, we need to make restrictions that forbid
37anyone to deny you these rights or to ask you to surrender the rights.
38These restrictions translate to certain responsibilities for you if you
39distribute copies of the software, or if you modify it.
40
41 For example, if you distribute copies of such a program, whether
42gratis or for a fee, you must give the recipients all the rights that
43you have. You must make sure that they, too, receive or can get the
44source code. And you must show them these terms so they know their
45rights.
46
47 We protect your rights with two steps: (1) copyright the software, and
48(2) offer you this license which gives you legal permission to copy,
49distribute and/or modify the software.
50
51 Also, for each author's protection and ours, we want to make certain
52that everyone understands that there is no warranty for this free
53software. If the software is modified by someone else and passed on, we
54want its recipients to know that what they have is not the original, so
55that any problems introduced by others will not reflect on the original
56authors' reputations.
57
58 Finally, any free program is threatened constantly by software
59patents. We wish to avoid the danger that redistributors of a free
60program will individually obtain patent licenses, in effect making the
61program proprietary. To prevent this, we have made it clear that any
62patent must be licensed for everyone's free use or not licensed at all.
63
64 The precise terms and conditions for copying, distribution and
65modification follow.
66
67 GNU GENERAL PUBLIC LICENSE
68 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
69
70 0. This License applies to any program or other work which contains
71a notice placed by the copyright holder saying it may be distributed
72under the terms of this General Public License. The "Program", below,
73refers to any such program or work, and a "work based on the Program"
74means either the Program or any derivative work under copyright law:
75that is to say, a work containing the Program or a portion of it,
76either verbatim or with modifications and/or translated into another
77language. (Hereinafter, translation is included without limitation in
78the term "modification".) Each licensee is addressed as "you".
79
80Activities other than copying, distribution and modification are not
81covered by this License; they are outside its scope. The act of
82running the Program is not restricted, and the output from the Program
83is covered only if its contents constitute a work based on the
84Program (independent of having been made by running the Program).
85Whether that is true depends on what the Program does.
86
87 1. You may copy and distribute verbatim copies of the Program's
88source code as you receive it, in any medium, provided that you
89conspicuously and appropriately publish on each copy an appropriate
90copyright notice and disclaimer of warranty; keep intact all the
91notices that refer to this License and to the absence of any warranty;
92and give any other recipients of the Program a copy of this License
93along with the Program.
94
95You may charge a fee for the physical act of transferring a copy, and
96you may at your option offer warranty protection in exchange for a fee.
97
98 2. You may modify your copy or copies of the Program or any portion
99of it, thus forming a work based on the Program, and copy and
100distribute such modifications or work under the terms of Section 1
101above, provided that you also meet all of these conditions:
102
103 a) You must cause the modified files to carry prominent notices
104 stating that you changed the files and the date of any change.
105
106 b) You must cause any work that you distribute or publish, that in
107 whole or in part contains or is derived from the Program or any
108 part thereof, to be licensed as a whole at no charge to all third
109 parties under the terms of this License.
110
111 c) If the modified program normally reads commands interactively
112 when run, you must cause it, when started running for such
113 interactive use in the most ordinary way, to print or display an
114 announcement including an appropriate copyright notice and a
115 notice that there is no warranty (or else, saying that you provide
116 a warranty) and that users may redistribute the program under
117 these conditions, and telling the user how to view a copy of this
118 License. (Exception: if the Program itself is interactive but
119 does not normally print such an announcement, your work based on
120 the Program is not required to print an announcement.)
121
122These requirements apply to the modified work as a whole. If
123identifiable sections of that work are not derived from the Program,
124and can be reasonably considered independent and separate works in
125themselves, then this License, and its terms, do not apply to those
126sections when you distribute them as separate works. But when you
127distribute the same sections as part of a whole which is a work based
128on the Program, the distribution of the whole must be on the terms of
129this License, whose permissions for other licensees extend to the
130entire whole, and thus to each and every part regardless of who wrote it.
131
132Thus, it is not the intent of this section to claim rights or contest
133your rights to work written entirely by you; rather, the intent is to
134exercise the right to control the distribution of derivative or
135collective works based on the Program.
136
137In addition, mere aggregation of another work not based on the Program
138with the Program (or with a work based on the Program) on a volume of
139a storage or distribution medium does not bring the other work under
140the scope of this License.
141
142 3. You may copy and distribute the Program (or a work based on it,
143under Section 2) in object code or executable form under the terms of
144Sections 1 and 2 above provided that you also do one of the following:
145
146 a) Accompany it with the complete corresponding machine-readable
147 source code, which must be distributed under the terms of Sections
148 1 and 2 above on a medium customarily used for software interchange; or,
149
150 b) Accompany it with a written offer, valid for at least three
151 years, to give any third party, for a charge no more than your
152 cost of physically performing source distribution, a complete
153 machine-readable copy of the corresponding source code, to be
154 distributed under the terms of Sections 1 and 2 above on a medium
155 customarily used for software interchange; or,
156
157 c) Accompany it with the information you received as to the offer
158 to distribute corresponding source code. (This alternative is
159 allowed only for noncommercial distribution and only if you
160 received the program in object code or executable form with such
161 an offer, in accord with Subsection b above.)
162
163The source code for a work means the preferred form of the work for
164making modifications to it. For an executable work, complete source
165code means all the source code for all modules it contains, plus any
166associated interface definition files, plus the scripts used to
167control compilation and installation of the executable. However, as a
168special exception, the source code distributed need not include
169anything that is normally distributed (in either source or binary
170form) with the major components (compiler, kernel, and so on) of the
171operating system on which the executable runs, unless that component
172itself accompanies the executable.
173
174If distribution of executable or object code is made by offering
175access to copy from a designated place, then offering equivalent
176access to copy the source code from the same place counts as
177distribution of the source code, even though third parties are not
178compelled to copy the source along with the object code.
179
180 4. You may not copy, modify, sublicense, or distribute the Program
181except as expressly provided under this License. Any attempt
182otherwise to copy, modify, sublicense or distribute the Program is
183void, and will automatically terminate your rights under this License.
184However, parties who have received copies, or rights, from you under
185this License will not have their licenses terminated so long as such
186parties remain in full compliance.
187
188 5. You are not required to accept this License, since you have not
189signed it. However, nothing else grants you permission to modify or
190distribute the Program or its derivative works. These actions are
191prohibited by law if you do not accept this License. Therefore, by
192modifying or distributing the Program (or any work based on the
193Program), you indicate your acceptance of this License to do so, and
194all its terms and conditions for copying, distributing or modifying
195the Program or works based on it.
196
197 6. Each time you redistribute the Program (or any work based on the
198Program), the recipient automatically receives a license from the
199original licensor to copy, distribute or modify the Program subject to
200these terms and conditions. You may not impose any further
201restrictions on the recipients' exercise of the rights granted herein.
202You are not responsible for enforcing compliance by third parties to
203this License.
204
205 7. If, as a consequence of a court judgment or allegation of patent
206infringement or for any other reason (not limited to patent issues),
207conditions are imposed on you (whether by court order, agreement or
208otherwise) that contradict the conditions of this License, they do not
209excuse you from the conditions of this License. If you cannot
210distribute so as to satisfy simultaneously your obligations under this
211License and any other pertinent obligations, then as a consequence you
212may not distribute the Program at all. For example, if a patent
213license would not permit royalty-free redistribution of the Program by
214all those who receive copies directly or indirectly through you, then
215the only way you could satisfy both it and this License would be to
216refrain entirely from distribution of the Program.
217
218If any portion of this section is held invalid or unenforceable under
219any particular circumstance, the balance of the section is intended to
220apply and the section as a whole is intended to apply in other
221circumstances.
222
223It is not the purpose of this section to induce you to infringe any
224patents or other property right claims or to contest validity of any
225such claims; this section has the sole purpose of protecting the
226integrity of the free software distribution system, which is
227implemented by public license practices. Many people have made
228generous contributions to the wide range of software distributed
229through that system in reliance on consistent application of that
230system; it is up to the author/donor to decide if he or she is willing
231to distribute software through any other system and a licensee cannot
232impose that choice.
233
234This section is intended to make thoroughly clear what is believed to
235be a consequence of the rest of this License.
236
237 8. If the distribution and/or use of the Program is restricted in
238certain countries either by patents or by copyrighted interfaces, the
239original copyright holder who places the Program under this License
240may add an explicit geographical distribution limitation excluding
241those countries, so that distribution is permitted only in or among
242countries not thus excluded. In such case, this License incorporates
243the limitation as if written in the body of this License.
244
245 9. The Free Software Foundation may publish revised and/or new versions
246of the General Public License from time to time. Such new versions will
247be similar in spirit to the present version, but may differ in detail to
248address new problems or concerns.
249
250Each version is given a distinguishing version number. If the Program
251specifies a version number of this License which applies to it and "any
252later version", you have the option of following the terms and conditions
253either of that version or of any later version published by the Free
254Software Foundation. If the Program does not specify a version number of
255this License, you may choose any version ever published by the Free Software
256Foundation.
257
258 10. If you wish to incorporate parts of the Program into other free
259programs whose distribution conditions are different, write to the author
260to ask for permission. For software which is copyrighted by the Free
261Software Foundation, write to the Free Software Foundation; we sometimes
262make exceptions for this. Our decision will be guided by the two goals
263of preserving the free status of all derivatives of our free software and
264of promoting the sharing and reuse of software generally.
265
266 NO WARRANTY
267
268 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
269FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
270OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
271PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
272OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
273MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
274TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
275PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
276REPAIR OR CORRECTION.
277
278 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
279WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
280REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
281INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
282OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
283TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
284YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
285PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
286POSSIBILITY OF SUCH DAMAGES.
287
288 END OF TERMS AND CONDITIONS
289
290 How to Apply These Terms to Your New Programs
291
292 If you develop a new program, and you want it to be of the greatest
293possible use to the public, the best way to achieve this is to make it
294free software which everyone can redistribute and change under these terms.
295
296 To do so, attach the following notices to the program. It is safest
297to attach them to the start of each source file to most effectively
298convey the exclusion of warranty; and each file should have at least
299the "copyright" line and a pointer to where the full notice is found.
300
301 <one line to give the program's name and a brief idea of what it does.>
302 Copyright (C) <year> <name of author>
303
304 This program is free software; you can redistribute it and/or modify
305 it under the terms of the GNU General Public License as published by
306 the Free Software Foundation; either version 2 of the License, or
307 (at your option) any later version.
308
309 This program is distributed in the hope that it will be useful,
310 but WITHOUT ANY WARRANTY; without even the implied warranty of
311 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
312 GNU General Public License for more details.
313
314 You should have received a copy of the GNU General Public License
315 along with this program; if not, write to the Free Software
316 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
317
318
319Also add information on how to contact you by electronic and paper mail.
320
321If the program is interactive, make it output a short notice like this
322when it starts in an interactive mode:
323
324 Gnomovision version 69, Copyright (C) year name of author
325 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
326 This is free software, and you are welcome to redistribute it
327 under certain conditions; type `show c' for details.
328
329The hypothetical commands `show w' and `show c' should show the appropriate
330parts of the General Public License. Of course, the commands you use may
331be called something other than `show w' and `show c'; they could even be
332mouse-clicks or menu items--whatever suits your program.
333
334You should also get your employer (if you work as a programmer) or your
335school, if any, to sign a "copyright disclaimer" for the program, if
336necessary. Here is a sample; alter the names:
337
338 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
339 `Gnomovision' (which makes passes at compilers) written by James Hacker.

342 Ty Coon, President of Vice
343
344This General Public License does not permit incorporating your program into
345proprietary programs. If your program is a subroutine library, you may
346consider it more useful to permit linking proprietary applications with the
347library. If this is what you want to do, use the GNU Library General
348Public License instead of this License.
