41 Version 2, June 1991
42
43 rizwank 1.1 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
44 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
45 Everyone is permitted to copy and distribute verbatim copies
46 of this license document, but changing it is not allowed.
47
48 Preamble
49
50 The licenses for most software are designed to take away your
51 freedom to share and change it. By contrast, the GNU General Public
52 License is intended to guarantee your freedom to share and change free
53 software--to make sure the software is free for all its users. This
54 General Public License applies to most of the Free Software
55 Foundation's software and to any other program whose authors commit to
56 using it. (Some other Free Software Foundation software is covered by
57 the GNU Library General Public License instead.) You can apply it to
58 your programs, too.
59
60 When we speak of free software, we are referring to freedom, not
61 price. Our General Public Licenses are designed to make sure that you
62 have the freedom to distribute copies of free software (and charge for
63 this service if you wish), that you receive source code or can get it
64 rizwank 1.1 if you want it, that you can change the software or use pieces of it
65 in new free programs; and that you know you can do these things.
66
67 To protect your rights, we need to make restrictions that forbid
68 anyone to deny you these rights or to ask you to surrender the rights.
69 These restrictions translate to certain responsibilities for you if you
70 distribute copies of the software, or if you modify it.
71
72 For example, if you distribute copies of such a program, whether
73 gratis or for a fee, you must give the recipients all the rights that
74 you have. You must make sure that they, too, receive or can get the
75 source code. And you must show them these terms so they know their
76 rights.
77
78 We protect your rights with two steps: (1) copyright the software, and
79 (2) offer you this license which gives you legal permission to copy,
80 distribute and/or modify the software.
81
82 Also, for each author's protection and ours, we want to make certain
83 that everyone understands that there is no warranty for this free
84 software. If the software is modified by someone else and passed on, we
85 rizwank 1.1 want its recipients to know that what they have is not the original, so
86 that any problems introduced by others will not reflect on the original
87 authors' reputations.
88
89 Finally, any free program is threatened constantly by software
90 patents. We wish to avoid the danger that redistributors of a free
91 program will individually obtain patent licenses, in effect making the
92 program proprietary. To prevent this, we have made it clear that any
93 patent must be licensed for everyone's free use or not licensed at all.
94
95 The precise terms and conditions for copying, distribution and
96 modification follow.
97
98 GNU GENERAL PUBLIC LICENSE
99 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
100
101 0. This License applies to any program or other work which contains
102 a notice placed by the copyright holder saying it may be distributed
103 under the terms of this General Public License. The "Program", below,
104 refers to any such program or work, and a "work based on the Program"
105 means either the Program or any derivative work under copyright law:
106 rizwank 1.1 that is to say, a work containing the Program or a portion of it,
107 either verbatim or with modifications and/or translated into another
108 language. (Hereinafter, translation is included without limitation in
109 the term "modification".) Each licensee is addressed as "you".
110
111 Activities other than copying, distribution and modification are not
112 covered by this License; they are outside its scope. The act of
113 running the Program is not restricted, and the output from the Program
114 is covered only if its contents constitute a work based on the
115 Program (independent of having been made by running the Program).
116 Whether that is true depends on what the Program does.
117
118 1. You may copy and distribute verbatim copies of the Program's
119 source code as you receive it, in any medium, provided that you
120 conspicuously and appropriately publish on each copy an appropriate
121 copyright notice and disclaimer of warranty; keep intact all the
122 notices that refer to this License and to the absence of any warranty;
123 and give any other recipients of the Program a copy of this License
124 along with the Program.
125
126 You may charge a fee for the physical act of transferring a copy, and
127 rizwank 1.1 you may at your option offer warranty protection in exchange for a fee.
128
129 2. You may modify your copy or copies of the Program or any portion
130 of it, thus forming a work based on the Program, and copy and
131 distribute such modifications or work under the terms of Section 1
132 above, provided that you also meet all of these conditions:
133
134 a) You must cause the modified files to carry prominent notices
135 stating that you changed the files and the date of any change.
136
137 b) You must cause any work that you distribute or publish, that in
138 whole or in part contains or is derived from the Program or any
139 part thereof, to be licensed as a whole at no charge to all third
140 parties under the terms of this License.
141
142 c) If the modified program normally reads commands interactively
143 when run, you must cause it, when started running for such
144 interactive use in the most ordinary way, to print or display an
145 announcement including an appropriate copyright notice and a
146 notice that there is no warranty (or else, saying that you provide
147 a warranty) and that users may redistribute the program under
148 rizwank 1.1 these conditions, and telling the user how to view a copy of this
149 License. (Exception: if the Program itself is interactive but
150 does not normally print such an announcement, your work based on
151 the Program is not required to print an announcement.)
152
153 These requirements apply to the modified work as a whole. If
154 identifiable sections of that work are not derived from the Program,
155 and can be reasonably considered independent and separate works in
156 themselves, then this License, and its terms, do not apply to those
157 sections when you distribute them as separate works. But when you
158 distribute the same sections as part of a whole which is a work based
159 on the Program, the distribution of the whole must be on the terms of
160 this License, whose permissions for other licensees extend to the
161 entire whole, and thus to each and every part regardless of who wrote it.
162
163 Thus, it is not the intent of this section to claim rights or contest
164 your rights to work written entirely by you; rather, the intent is to
165 exercise the right to control the distribution of derivative or
166 collective works based on the Program.
167
168 In addition, mere aggregation of another work not based on the Program
169 rizwank 1.1 with the Program (or with a work based on the Program) on a volume of
170 a storage or distribution medium does not bring the other work under
171 the scope of this License.
172
173 3. You may copy and distribute the Program (or a work based on it,
174 under Section 2) in object code or executable form under the terms of
175 Sections 1 and 2 above provided that you also do one of the following:
176
177 a) Accompany it with the complete corresponding machine-readable
178 source code, which must be distributed under the terms of Sections
179 1 and 2 above on a medium customarily used for software interchange; or,
180
181 b) Accompany it with a written offer, valid for at least three
182 years, to give any third party, for a charge no more than your
183 cost of physically performing source distribution, a complete
184 machine-readable copy of the corresponding source code, to be
185 distributed under the terms of Sections 1 and 2 above on a medium
186 customarily used for software interchange; or,
187
188 c) Accompany it with the information you received as to the offer
189 to distribute corresponding source code. (This alternative is
190 rizwank 1.1 allowed only for noncommercial distribution and only if you
191 received the program in object code or executable form with such
192 an offer, in accord with Subsection b above.)
193
194 The source code for a work means the preferred form of the work for
195 making modifications to it. For an executable work, complete source
196 code means all the source code for all modules it contains, plus any
197 associated interface definition files, plus the scripts used to
198 control compilation and installation of the executable. However, as a
199 special exception, the source code distributed need not include
200 anything that is normally distributed (in either source or binary
201 form) with the major components (compiler, kernel, and so on) of the
202 operating system on which the executable runs, unless that component
203 itself accompanies the executable.
204
205 If distribution of executable or object code is made by offering
206 access to copy from a designated place, then offering equivalent
207 access to copy the source code from the same place counts as
208 distribution of the source code, even though third parties are not
209 compelled to copy the source along with the object code.
210
211 rizwank 1.1 4. You may not copy, modify, sublicense, or distribute the Program
212 except as expressly provided under this License. Any attempt
213 otherwise to copy, modify, sublicense or distribute the Program is
214 void, and will automatically terminate your rights under this License.
215 However, parties who have received copies, or rights, from you under
216 this License will not have their licenses terminated so long as such
217 parties remain in full compliance.
218
219 5. You are not required to accept this License, since you have not
220 signed it. However, nothing else grants you permission to modify or
221 distribute the Program or its derivative works. These actions are
222 prohibited by law if you do not accept this License. Therefore, by
223 modifying or distributing the Program (or any work based on the
224 Program), you indicate your acceptance of this License to do so, and
225 all its terms and conditions for copying, distributing or modifying
226 the Program or works based on it.
227
228 6. Each time you redistribute the Program (or any work based on the
229 Program), the recipient automatically receives a license from the
230 original licensor to copy, distribute or modify the Program subject to
231 these terms and conditions. You may not impose any further
232 rizwank 1.1 restrictions on the recipients' exercise of the rights granted herein.
233 You are not responsible for enforcing compliance by third parties to
234 this License.
235
236 7. If, as a consequence of a court judgment or allegation of patent
237 infringement or for any other reason (not limited to patent issues),
238 conditions are imposed on you (whether by court order, agreement or
239 otherwise) that contradict the conditions of this License, they do not
240 excuse you from the conditions of this License. If you cannot
241 distribute so as to satisfy simultaneously your obligations under this
242 License and any other pertinent obligations, then as a consequence you
243 may not distribute the Program at all. For example, if a patent
244 license would not permit royalty-free redistribution of the Program by
245 all those who receive copies directly or indirectly through you, then
246 the only way you could satisfy both it and this License would be to
247 refrain entirely from distribution of the Program.
248
249 If any portion of this section is held invalid or unenforceable under
250 any particular circumstance, the balance of the section is intended to
251 apply and the section as a whole is intended to apply in other
252 circumstances.
253 rizwank 1.1
254 It is not the purpose of this section to induce you to infringe any
255 patents or other property right claims or to contest validity of any
256 such claims; this section has the sole purpose of protecting the
257 integrity of the free software distribution system, which is
258 implemented by public license practices. Many people have made
259 generous contributions to the wide range of software distributed
260 through that system in reliance on consistent application of that
261 system; it is up to the author/donor to decide if he or she is willing
262 to distribute software through any other system and a licensee cannot
263 impose that choice.
264
265 This section is intended to make thoroughly clear what is believed to
266 be a consequence of the rest of this License.
267
268 8. If the distribution and/or use of the Program is restricted in
269 certain countries either by patents or by copyrighted interfaces, the
270 original copyright holder who places the Program under this License
271 may add an explicit geographical distribution limitation excluding
272 those countries, so that distribution is permitted only in or among
273 countries not thus excluded. In such case, this License incorporates
274 rizwank 1.1 the limitation as if written in the body of this License.
275
276 9. The Free Software Foundation may publish revised and/or new versions
277 of the General Public License from time to time. Such new versions will
278 be similar in spirit to the present version, but may differ in detail to
279 address new problems or concerns.
280
281 Each version is given a distinguishing version number. If the Program
282 specifies a version number of this License which applies to it and "any
283 later version", you have the option of following the terms and conditions
284 either of that version or of any later version published by the Free
285 Software Foundation. If the Program does not specify a version number of
286 this License, you may choose any version ever published by the Free Software
287 Foundation.
288
289 10. If you wish to incorporate parts of the Program into other free
290 programs whose distribution conditions are different, write to the author
291 to ask for permission. For software which is copyrighted by the Free
292 Software Foundation, write to the Free Software Foundation; we sometimes
293 make exceptions for this. Our decision will be guided by the two goals
294 of preserving the free status of all derivatives of our free software and
295 rizwank 1.1 of promoting the sharing and reuse of software generally.
296
297 NO WARRANTY
298
299 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
300 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
301 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
302 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
303 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
304 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
305 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
306 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
307 REPAIR OR CORRECTION.
308
309 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
310 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
311 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
312 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
313 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
314 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
315 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
316 rizwank 1.1 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
317 POSSIBILITY OF SUCH DAMAGES.
318
319 END OF TERMS AND CONDITIONS
320
321 How to Apply These Terms to Your New Programs
322
323 If you develop a new program, and you want it to be of the greatest
324 possible use to the public, the best way to achieve this is to make it
325 free software which everyone can redistribute and change under these terms.
326
327 To do so, attach the following notices to the program. It is safest
328 to attach them to the start of each source file to most effectively
329 convey the exclusion of warranty; and each file should have at least
330 the "copyright" line and a pointer to where the full notice is found.
331
332 <one line to give the program's name and a brief idea of what it does.>
333 Copyright (C) <year> <name of author>
334
335 This program is free software; you can redistribute it and/or modify
336 it under the terms of the GNU General Public License as published by
337 rizwank 1.1 the Free Software Foundation; either version 2 of the License, or
338 (at your option) any later version.
339
340 This program is distributed in the hope that it will be useful,
341 but WITHOUT ANY WARRANTY; without even the implied warranty of
342 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
343 GNU General Public License for more details.
344
345 You should have received a copy of the GNU General Public License
346 along with this program; if not, write to the Free Software
347 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
348
349
350 Also add information on how to contact you by electronic and paper mail.
351
352 If the program is interactive, make it output a short notice like this
353 when it starts in an interactive mode:
354
355 Gnomovision version 69, Copyright (C) year name of author
356 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
357 This is free software, and you are welcome to redistribute it
358 rizwank 1.1 under certain conditions; type `show c' for details.
359
360 The hypothetical commands `show w' and `show c' should show the appropriate
361 parts of the General Public License. Of course, the commands you use may
362 be called something other than `show w' and `show c'; they could even be
363 mouse-clicks or menu items--whatever suits your program.
364
365 You should also get your employer (if you work as a programmer) or your
366 school, if any, to sign a "copyright disclaimer" for the program, if
367 necessary. Here is a sample; alter the names:
368
369 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
370 `Gnomovision' (which makes passes at compilers) written by James Hacker.
371
372 <signature of Ty Coon>, 1 April 1989
373 Ty Coon, President of Vice
374
375 This General Public License does not permit incorporating your program into
376 proprietary programs. If your program is a subroutine library, you may
377 consider it more useful to permit linking proprietary applications with the
378 library. If this is what you want to do, use the GNU Library General
379 rizwank 1.1 Public License instead of this License.
