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