22 <p> Copyright (C) 1989, 1991 Free Software Foundation, Inc.
23 <br> 675 Mass Ave, Cambridge, MA 02139, USA
24 <br> Everyone is permitted to copy and distribute verbatim copies
25 <br> of this license document, but changing it is not allowed.
26
27 <h3 align=center>Preamble</h3>
28
29 <p>
30 The licenses for most software are designed to take away your
31 freedom to share and change it. By contrast, the GNU General Public
32 License is intended to guarantee your freedom to share and change free
33 software&mdash;to make sure the software is free for all its users. This
34 General Public License applies to most of the Free Software
35 Foundation's software and to any other program whose authors commit to
36 using it. (Some other Free Software Foundation software is covered by
37 the GNU Library General Public License instead.) You can apply it to
38 your programs, too.
39
40 <p>
41 When we speak of free software, we are referring to freedom, not
42 price. Our General Public Licenses are designed to make sure that you
43 have the freedom to distribute copies of free software (and charge for
44 this service if you wish), that you receive source code or can get it
45 if you want it, that you can change the software or use pieces of it
46 in new free programs; and that you know you can do these things.
47
48 <p>
49 To protect your rights, we need to make restrictions that forbid
50 anyone to deny you these rights or to ask you to surrender the rights.
51 These restrictions translate to certain responsibilities for you if you
52 distribute copies of the software, or if you modify it.
53
54 <p>
55 For example, if you distribute copies of such a program, whether
56 gratis or for a fee, you must give the recipients all the rights that
57 you have. You must make sure that they, too, receive or can get the
58 source code. And you must show them these terms so they know their
59 rights.
60
61 <p>
62 We protect your rights with two steps: (1) copyright the software, and
63 (2) offer you this license which gives you legal permission to copy,
64 distribute and/or modify the software.
65
66 <p>
67 Also, for each author's protection and ours, we want to make certain
68 that everyone understands that there is no warranty for this free
69 software. If the software is modified by someone else and passed on, we
70 want its recipients to know that what they have is not the original, so
71 that any problems introduced by others will not reflect on the original
72 authors' reputations.
73
74 <p>
75 Finally, any free program is threatened constantly by software
76 patents. We wish to avoid the danger that redistributors of a free
77 program will individually obtain patent licenses, in effect making the
78 program proprietary. To prevent this, we have made it clear that any
79 patent must be licensed for everyone's free use or not licensed at all.
80
81 <p>
82 The precise terms and conditions for copying, distribution and
83 modification follow.
84

86 <h3 align=center>GNU GENERAL PUBLIC LICENSE</h3>
87
88 <p align=center>
89 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
90
91 <p>
92 0. This License applies to any program or other work which contains
93 a notice placed by the copyright holder saying it may be distributed
94 under the terms of this General Public License. The "Program", below,
95 refers to any such program or work, and a "work based on the Program"
96 means either the Program or any derivative work under copyright law:
97 that is to say, a work containing the Program or a portion of it,
98 either verbatim or with modifications and/or translated into another
99 language. (Hereinafter, translation is included without limitation in
100 the term "modification".) Each licensee is addressed as "you".
101
102 <p>
103 Activities other than copying, distribution and modification are not
104 covered by this License; they are outside its scope. The act of
105 running the Program is not restricted, and the output from the Program
106 is covered only if its contents constitute a work based on the
107 Program (independent of having been made by running the Program).
108 Whether that is true depends on what the Program does.
109
110 <p>
111 1. You may copy and distribute verbatim copies of the Program's
112 source code as you receive it, in any medium, provided that you
113 conspicuously and appropriately publish on each copy an appropriate
114 copyright notice and disclaimer of warranty; keep intact all the
115 notices that refer to this License and to the absence of any warranty;
116 and give any other recipients of the Program a copy of this License
117 along with the Program.
118
119 <p>
120 You may charge a fee for the physical act of transferring a copy, and
121 you may at your option offer warranty protection in exchange for a fee.
122
123 <p>
124 2. You may modify your copy or copies of the Program or any portion
125 of it, thus forming a work based on the Program, and copy and
126 distribute such modifications or work under the terms of Section 1
127 above, provided that you also meet all of these conditions:
128
129 <p><blockquote>
130 a) You must cause the modified files to carry prominent notices
131 stating that you changed the files and the date of any change.
132
133 <p>
134 b) You must cause any work that you distribute or publish, that in
135 whole or in part contains or is derived from the Program or any
136 part thereof, to be licensed as a whole at no charge to all third
137 parties under the terms of this License.
138
139 <p>
140 c) If the modified program normally reads commands interactively
141 when run, you must cause it, when started running for such
142 interactive use in the most ordinary way, to print or display an
143 announcement including an appropriate copyright notice and a
144 notice that there is no warranty (or else, saying that you provide
145 a warranty) and that users may redistribute the program under
146 these conditions, and telling the user how to view a copy of this
147 License. (Exception: if the Program itself is interactive but
148 does not normally print such an announcement, your work based on
149 the Program is not required to print an announcement.)
150 </blockquote>
151
152 <p>
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 <p>
164 Thus, it is not the intent of this section to claim rights or contest
165 your rights to work written entirely by you; rather, the intent is to
166 exercise the right to control the distribution of derivative or
167 collective works based on the Program.
168
169 <p>
170 In addition, mere aggregation of another work not based on the Program
171 with the Program (or with a work based on the Program) on a volume of
172 a storage or distribution medium does not bring the other work under
173 the scope of this License.
174
175 <p>
176 3. You may copy and distribute the Program (or a work based on it,
177 under Section 2) in object code or executable form under the terms of
178 Sections 1 and 2 above provided that you also do one of the following:
179
180 <p><blockquote>
181 a) Accompany it with the complete corresponding machine-readable
182 source code, which must be distributed under the terms of Sections
183 1 and 2 above on a medium customarily used for software interchange; or,
184
185 <p>
186 b) Accompany it with a written offer, valid for at least three
187 years, to give any third party, for a charge no more than your
188 cost of physically performing source distribution, a complete
189 machine-readable copy of the corresponding source code, to be
190 distributed under the terms of Sections 1 and 2 above on a medium
191 customarily used for software interchange; or,
192
193 <p>
194 c) Accompany it with the information you received as to the offer
195 to distribute corresponding source code. (This alternative is
196 allowed only for noncommercial distribution and only if you
197 received the program in object code or executable form with such
198 an offer, in accord with Subsection b above.)
199 </blockquote>
200
201 <p>
202 The source code for a work means the preferred form of the work for
203 making modifications to it. For an executable work, complete source
204 code means all the source code for all modules it contains, plus any
205 associated interface definition files, plus the scripts used to
206 control compilation and installation of the executable. However, as a
207 special exception, the source code distributed need not include
208 anything that is normally distributed (in either source or binary
209 form) with the major components (compiler, kernel, and so on) of the
210 operating system on which the executable runs, unless that component
211 itself accompanies the executable.
212
213 <p>
214 If distribution of executable or object code is made by offering
215 access to copy from a designated place, then offering equivalent
216 access to copy the source code from the same place counts as
217 distribution of the source code, even though third parties are not
218 compelled to copy the source along with the object code.
219
220 <p>
221 4. You may not copy, modify, sublicense, or distribute the Program
222 except as expressly provided under this License. Any attempt
223 otherwise to copy, modify, sublicense or distribute the Program is
224 void, and will automatically terminate your rights under this License.
225 However, parties who have received copies, or rights, from you under
226 this License will not have their licenses terminated so long as such
227 parties remain in full compliance.
228
229 <p>
230 5. You are not required to accept this License, since you have not
231 signed it. However, nothing else grants you permission to modify or
232 distribute the Program or its derivative works. These actions are
233 prohibited by law if you do not accept this License. Therefore, by
234 modifying or distributing the Program (or any work based on the
235 Program), you indicate your acceptance of this License to do so, and
236 all its terms and conditions for copying, distributing or modifying
237 the Program or works based on it.
238
239 <p>
240 6. Each time you redistribute the Program (or any work based on the
241 Program), the recipient automatically receives a license from the
242 original licensor to copy, distribute or modify the Program subject to
243 these terms and conditions. You may not impose any further
244 restrictions on the recipients' exercise of the rights granted herein.
245 You are not responsible for enforcing compliance by third parties to
246 this License.
247
248 <p>
249 7. If, as a consequence of a court judgment or allegation of patent
250 infringement or for any other reason (not limited to patent issues),
251 conditions are imposed on you (whether by court order, agreement or
252 otherwise) that contradict the conditions of this License, they do not
253 excuse you from the conditions of this License. If you cannot
254 distribute so as to satisfy simultaneously your obligations under this
255 License and any other pertinent obligations, then as a consequence you
256 may not distribute the Program at all. For example, if a patent
257 license would not permit royalty-free redistribution of the Program by
258 all those who receive copies directly or indirectly through you, then
259 the only way you could satisfy both it and this License would be to
260 refrain entirely from distribution of the Program.
261
262 <p>
263 If any portion of this section is held invalid or unenforceable under
264 any particular circumstance, the balance of the section is intended to
265 apply and the section as a whole is intended to apply in other
266 circumstances.
267
268 <p>
269 It is not the purpose of this section to induce you to infringe any
270 patents or other property right claims or to contest validity of any
271 such claims; this section has the sole purpose of protecting the
272 integrity of the free software distribution system, which is
273 implemented by public license practices. Many people have made
274 generous contributions to the wide range of software distributed
275 through that system in reliance on consistent application of that
276 system; it is up to the author/donor to decide if he or she is willing
277 to distribute software through any other system and a licensee cannot
278 impose that choice.
279
280 <p>
281 This section is intended to make thoroughly clear what is believed to
282 be a consequence of the rest of this License.
283
284 <p>
285 8. If the distribution and/or use of the Program is restricted in
286 certain countries either by patents or by copyrighted interfaces, the
287 original copyright holder who places the Program under this License
288 may add an explicit geographical distribution limitation excluding
289 those countries, so that distribution is permitted only in or among
290 countries not thus excluded. In such case, this License incorporates
291 the limitation as if written in the body of this License.
292
293 <p>
294 9. The Free Software Foundation may publish revised and/or new versions
295 of the General Public License from time to time. Such new versions will
296 be similar in spirit to the present version, but may differ in detail to
297 address new problems or concerns.
298
299 <p>
300 Each version is given a distinguishing version number. If the Program
301 specifies a version number of this License which applies to it and "any
302 later version", you have the option of following the terms and conditions
303 either of that version or of any later version published by the Free
304 Software Foundation. If the Program does not specify a version number of
305 this License, you may choose any version ever published by the Free Software
306 Foundation.
307
308 <p>
309 10. If you wish to incorporate parts of the Program into other free
310 programs whose distribution conditions are different, write to the author
311 to ask for permission. For software which is copyrighted by the Free
312 Software Foundation, write to the Free Software Foundation; we sometimes
313 make exceptions for this. Our decision will be guided by the two goals
314 of preserving the free status of all derivatives of our free software and
315 of promoting the sharing and reuse of software generally.
316
317 <p align=center>NO WARRANTY
318
319 <p>
320 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
321 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
322 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
323 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
324 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
325 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
326 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
327 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
328 REPAIR OR CORRECTION.
329
330 <p>
331 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
332 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
333 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
334 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
335 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
336 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
337 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
338 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
339 POSSIBILITY OF SUCH DAMAGES.
340
341 <p align=center>END OF TERMS AND CONDITIONS
342
343 <p><hr>
344
345 <h3 align=center>Appendix: How to Apply These Terms to Your New Programs</h3>
346
347 <p>
348 If you develop a new program, and you want it to be of the greatest
349 possible use to the public, the best way to achieve this is to make it
350 free software which everyone can redistribute and change under these terms.
351
352 <p>
353 To do so, attach the following notices to the program. It is safest
354 to attach them to the start of each source file to most effectively
355 convey the exclusion of warranty; and each file should have at least
356 the "copyright" line and a pointer to where the full notice is found.
357
358 <p><pre>
359 &lt;one line to give the program's name and a brief idea of what it does.&gt;
360 Copyright (C) 19yy &lt;name of author&gt;
361
362 This program is free software; you can redistribute it and/or modify
363 it under the terms of the GNU General Public License as published by
364 the Free Software Foundation; either version 2 of the License, or
365 (at your option) any later version.
366
367 This program is distributed in the hope that it will be useful,
368 but WITHOUT ANY WARRANTY; without even the implied warranty of
369 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
370 GNU General Public License for more details.
371
372 You should have received a copy of the GNU General Public License
373 along with this program; if not, write to the Free Software
374 Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
375 </pre>
376
377 <p>
378 Also add information on how to contact you by electronic and paper mail.
379
380 <p>
381 If the program is interactive, make it output a short notice like this
382 when it starts in an interactive mode:
383
384 <p><pre>
385 Gnomovision version 69, Copyright (C) 19yy name of author
386 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
387 This is free software, and you are welcome to redistribute it
388 under certain conditions; type `show c' for details.
389 </pre>
390
391 <p>
392 The hypothetical commands `show w' and `show c' should show the appropriate
393 parts of the General Public License. Of course, the commands you use may
394 be called something other than `show w' and `show c'; they could even be
395 mouse-clicks or menu items&mdash;whatever suits your program.
396
397 <p>
398 You should also get your employer (if you work as a programmer) or your
399 school, if any, to sign a "copyright disclaimer" for the program, if
400 necessary. Here is a sample; alter the names:
401
402 <p><blockquote>
403 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
404 `Gnomovision' (which makes passes at compilers) written by James Hacker.
405
406 <p>
407 &lt;signature of Ty Coon&gt;, 1 April 1989
408 <br>Ty Coon, President of Vice
409 </blockquote>
410
411 <p>
412 This General Public License does not permit incorporating your program into
413 proprietary programs. If your program is a subroutine library, you may
414 consider it more useful to permit linking proprietary applications with the
415 library. If this is what you want to do, use the GNU Library General
416 Public License instead of this License.
