8 GNU GENERAL PUBLIC LICENSE
9 Version 2, June 1991
10
11 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
12 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
13 Everyone is permitted to copy and distribute verbatim copies
14 of this license document, but changing it is not allowed.
15
16 Preamble
17
18 The licenses for most software are designed to take away your
19 freedom to share and change it. By contrast, the GNU General Public
20 License is intended to guarantee your freedom to share and change free
21 software--to make sure the software is free for all its users. This
22 General Public License applies to most of the Free Software
23 Foundation's software and to any other program whose authors commit to
24 using it. (Some other Free Software Foundation software is covered by
25 the GNU Library General Public License instead.) You can apply it to
26 your programs, too.
27
28 When we speak of free software, we are referring to freedom, not
29 price. Our General Public Licenses are designed to make sure that you
30 have the freedom to distribute copies of free software (and charge for
31 this service if you wish), that you receive source code or can get it
32 if you want it, that you can change the software or use pieces of it
33 in new free programs; and that you know you can do these things.
34
35 To protect your rights, we need to make restrictions that forbid
36 anyone to deny you these rights or to ask you to surrender the rights.
37 These restrictions translate to certain responsibilities for you if you
38 distribute copies of the software, or if you modify it.
39
40 For example, if you distribute copies of such a program, whether
41 gratis or for a fee, you must give the recipients all the rights that
42 you have. You must make sure that they, too, receive or can get the
43 source code. And you must show them these terms so they know their
44 rights.
45
46 We protect your rights with two steps: (1) copyright the software, and
47 (2) offer you this license which gives you legal permission to copy,
48 distribute and/or modify the software.
49
50 Also, for each author's protection and ours, we want to make certain
51 that everyone understands that there is no warranty for this free
52 software. If the software is modified by someone else and passed on, we
53 want its recipients to know that what they have is not the original, so
54 that any problems introduced by others will not reflect on the original
55 authors' reputations.
56
57 Finally, any free program is threatened constantly by software
58 patents. We wish to avoid the danger that redistributors of a free
59 program will individually obtain patent licenses, in effect making the
60 program proprietary. To prevent this, we have made it clear that any
61 patent must be licensed for everyone's free use or not licensed at all.
62
63 The precise terms and conditions for copying, distribution and
64 modification follow.
65
66 GNU GENERAL PUBLIC LICENSE
67 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
68
69 0. This License applies to any program or other work which contains
70 a notice placed by the copyright holder saying it may be distributed
71 under the terms of this General Public License. The "Program", below,
72 refers to any such program or work, and a "work based on the Program"
73 means either the Program or any derivative work under copyright law:
74 that is to say, a work containing the Program or a portion of it,
75 either verbatim or with modifications and/or translated into another
76 language. (Hereinafter, translation is included without limitation in
77 the term "modification".) Each licensee is addressed as "you".
78
79 Activities other than copying, distribution and modification are not
80 covered by this License; they are outside its scope. The act of
81 running the Program is not restricted, and the output from the Program
82 is covered only if its contents constitute a work based on the
83 Program (independent of having been made by running the Program).
84 Whether that is true depends on what the Program does.
85
86 1. You may copy and distribute verbatim copies of the Program's
87 source code as you receive it, in any medium, provided that you
88 conspicuously and appropriately publish on each copy an appropriate
89 copyright notice and disclaimer of warranty; keep intact all the
90 notices that refer to this License and to the absence of any warranty;
91 and give any other recipients of the Program a copy of this License
92 along with the Program.
93
94 You may charge a fee for the physical act of transferring a copy, and
95 you may at your option offer warranty protection in exchange for a fee.
96
97 2. You may modify your copy or copies of the Program or any portion
98 of it, thus forming a work based on the Program, and copy and
99 distribute such modifications or work under the terms of Section 1
100 above, provided that you also meet all of these conditions:
101
102 a) You must cause the modified files to carry prominent notices
103 stating that you changed the files and the date of any change.
104
105 b) You must cause any work that you distribute or publish, that in
106 whole or in part contains or is derived from the Program or any
107 part thereof, to be licensed as a whole at no charge to all third
108 parties under the terms of this License.
109
110 c) If the modified program normally reads commands interactively
111 when run, you must cause it, when started running for such
112 interactive use in the most ordinary way, to print or display an
113 announcement including an appropriate copyright notice and a
114 notice that there is no warranty (or else, saying that you provide
115 a warranty) and that users may redistribute the program under
116 these conditions, and telling the user how to view a copy of this
117 License. (Exception: if the Program itself is interactive but
118 does not normally print such an announcement, your work based on
119 the Program is not required to print an announcement.)
120
121 These requirements apply to the modified work as a whole. If
122 identifiable sections of that work are not derived from the Program,
123 and can be reasonably considered independent and separate works in
124 themselves, then this License, and its terms, do not apply to those
125 sections when you distribute them as separate works. But when you
126 distribute the same sections as part of a whole which is a work based
127 on the Program, the distribution of the whole must be on the terms of
128 this License, whose permissions for other licensees extend to the
129 entire whole, and thus to each and every part regardless of who wrote it.
130
131 Thus, it is not the intent of this section to claim rights or contest
132 your rights to work written entirely by you; rather, the intent is to
133 exercise the right to control the distribution of derivative or
134 collective works based on the Program.
135
136 In addition, mere aggregation of another work not based on the Program
137 with the Program (or with a work based on the Program) on a volume of
138 a storage or distribution medium does not bring the other work under
139 the scope of this License.
140
141 3. You may copy and distribute the Program (or a work based on it,
142 under Section 2) in object code or executable form under the terms of
143 Sections 1 and 2 above provided that you also do one of the following:
144
145 a) Accompany it with the complete corresponding machine-readable
146 source code, which must be distributed under the terms of Sections
147 1 and 2 above on a medium customarily used for software interchange; or,
148
149 b) Accompany it with a written offer, valid for at least three
150 years, to give any third party, for a charge no more than your
151 cost of physically performing source distribution, a complete
152 machine-readable copy of the corresponding source code, to be
153 distributed under the terms of Sections 1 and 2 above on a medium
154 customarily used for software interchange; or,
155
156 c) Accompany it with the information you received as to the offer
157 to distribute corresponding source code. (This alternative is
158 allowed only for noncommercial distribution and only if you
159 received the program in object code or executable form with such
160 an offer, in accord with Subsection b above.)
161
162 The source code for a work means the preferred form of the work for
163 making modifications to it. For an executable work, complete source
164 code means all the source code for all modules it contains, plus any
165 associated interface definition files, plus the scripts used to
166 control compilation and installation of the executable. However, as a
167 special exception, the source code distributed need not include
168 anything that is normally distributed (in either source or binary
169 form) with the major components (compiler, kernel, and so on) of the
170 operating system on which the executable runs, unless that component
171 itself accompanies the executable.
172
173 If distribution of executable or object code is made by offering
174 access to copy from a designated place, then offering equivalent
175 access to copy the source code from the same place counts as
176 distribution of the source code, even though third parties are not
177 compelled to copy the source along with the object code.
178
179 4. You may not copy, modify, sublicense, or distribute the Program
180 except as expressly provided under this License. Any attempt
181 otherwise to copy, modify, sublicense or distribute the Program is
182 void, and will automatically terminate your rights under this License.
183 However, parties who have received copies, or rights, from you under
184 this License will not have their licenses terminated so long as such
185 parties remain in full compliance.
186
187 5. You are not required to accept this License, since you have not
188 signed it. However, nothing else grants you permission to modify or
189 distribute the Program or its derivative works. These actions are
190 prohibited by law if you do not accept this License. Therefore, by
191 modifying or distributing the Program (or any work based on the
192 Program), you indicate your acceptance of this License to do so, and
193 all its terms and conditions for copying, distributing or modifying
194 the Program or works based on it.
195
196 6. Each time you redistribute the Program (or any work based on the
197 Program), the recipient automatically receives a license from the
198 original licensor to copy, distribute or modify the Program subject to
199 these terms and conditions. You may not impose any further
200 restrictions on the recipients' exercise of the rights granted herein.
201 You are not responsible for enforcing compliance by third parties to
202 this License.
203
204 7. If, as a consequence of a court judgment or allegation of patent
205 infringement or for any other reason (not limited to patent issues),
206 conditions are imposed on you (whether by court order, agreement or
207 otherwise) that contradict the conditions of this License, they do not
208 excuse you from the conditions of this License. If you cannot
209 distribute so as to satisfy simultaneously your obligations under this
210 License and any other pertinent obligations, then as a consequence you
211 may not distribute the Program at all. For example, if a patent
212 license would not permit royalty-free redistribution of the Program by
213 all those who receive copies directly or indirectly through you, then
214 the only way you could satisfy both it and this License would be to
215 refrain entirely from distribution of the Program.
216
217 If any portion of this section is held invalid or unenforceable under
218 any particular circumstance, the balance of the section is intended to
219 apply and the section as a whole is intended to apply in other
220 circumstances.
221
222 It is not the purpose of this section to induce you to infringe any
223 patents or other property right claims or to contest validity of any
224 such claims; this section has the sole purpose of protecting the
225 integrity of the free software distribution system, which is
226 implemented by public license practices. Many people have made
227 generous contributions to the wide range of software distributed
228 through that system in reliance on consistent application of that
229 system; it is up to the author/donor to decide if he or she is willing
230 to distribute software through any other system and a licensee cannot
231 impose that choice.
232
233 This section is intended to make thoroughly clear what is believed to
234 be a consequence of the rest of this License.
235
236 8. If the distribution and/or use of the Program is restricted in
237 certain countries either by patents or by copyrighted interfaces, the
238 original copyright holder who places the Program under this License
239 may add an explicit geographical distribution limitation excluding
240 those countries, so that distribution is permitted only in or among
241 countries not thus excluded. In such case, this License incorporates
242 the limitation as if written in the body of this License.
243
244 9. The Free Software Foundation may publish revised and/or new versions
245 of the General Public License from time to time. Such new versions will
246 be similar in spirit to the present version, but may differ in detail to
247 address new problems or concerns.
248
249 Each version is given a distinguishing version number. If the Program
250 specifies a version number of this License which applies to it and "any
251 later version", you have the option of following the terms and conditions
252 either of that version or of any later version published by the Free
253 Software Foundation. If the Program does not specify a version number of
254 this License, you may choose any version ever published by the Free Software
255 Foundation.
256
257 10. If you wish to incorporate parts of the Program into other free
258 programs whose distribution conditions are different, write to the author
259 to ask for permission. For software which is copyrighted by the Free
260 Software Foundation, write to the Free Software Foundation; we sometimes
261 make exceptions for this. Our decision will be guided by the two goals
262 of preserving the free status of all derivatives of our free software and
263 of promoting the sharing and reuse of software generally.
264
265 NO WARRANTY
266
267 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
268 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
269 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
270 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
271 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
272 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
273 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
274 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
275 REPAIR OR CORRECTION.
276
277 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
278 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
279 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
280 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
281 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
282 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
283 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
284 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
285 POSSIBILITY OF SUCH DAMAGES.
286
287 END OF TERMS AND CONDITIONS
288
289 How to Apply These Terms to Your New Programs
290
291 If you develop a new program, and you want it to be of the greatest
292 possible use to the public, the best way to achieve this is to make it
293 free software which everyone can redistribute and change under these terms.
294
295 To do so, attach the following notices to the program. It is safest
296 to attach them to the start of each source file to most effectively
297 convey the exclusion of warranty; and each file should have at least
298 the "copyright" line and a pointer to where the full notice is found.
299
300 <one line to give the program's name and a brief idea of what it does.>
301 Copyright (C) <year> <name of author>
302
303 This program is free software; you can redistribute it and/or modify
304 it under the terms of the GNU General Public License as published by
305 the Free Software Foundation; either version 2 of the License, or
306 (at your option) any later version.
307
308 This program is distributed in the hope that it will be useful,
309 but WITHOUT ANY WARRANTY; without even the implied warranty of
310 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
311 GNU General Public License for more details.
312
313 You should have received a copy of the GNU General Public License
314 along with this program; if not, write to the Free Software
315 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
316
317
318 Also add information on how to contact you by electronic and paper mail.
319
320 If the program is interactive, make it output a short notice like this
321 when it starts in an interactive mode:
322
323 Gnomovision version 69, Copyright (C) year name of author
324 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
325 This is free software, and you are welcome to redistribute it
326 under certain conditions; type `show c' for details.
327
328 The hypothetical commands `show w' and `show c' should show the appropriate
329 parts of the General Public License. Of course, the commands you use may
330 be called something other than `show w' and `show c'; they could even be
331 mouse-clicks or menu items--whatever suits your program.
332
333 You should also get your employer (if you work as a programmer) or your
334 school, if any, to sign a "copyright disclaimer" for the program, if
335 necessary. Here is a sample; alter the names:
336
337 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
338 `Gnomovision' (which makes passes at compilers) written by James Hacker.
339

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