24 <h3>Version 2, June 1991</h3>
25 <p>
26 Copyright (C) 1989, 1991 Free Software Foundation, Inc.<br>
27 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA<br>
28 Everyone is permitted to copy and distribute verbatim copies<br>
29 of this license document, but changing it is not allowed.<br>
30 </p>
31 <h3>Preamble</h3>
32 <p>
33 The licenses for most software are designed to take away your
34 freedom to share and change it. By contrast, the GNU General Public
35 License is intended to guarantee your freedom to share and change free
36 software--to make sure the software is free for all its users. This
37 General Public License applies to most of the Free Software
38 Foundation's software and to any other program whose authors commit to
39 using it. (Some other Free Software Foundation software is covered by
40 the GNU Lesser General Public License instead.) You can apply it to
41 your programs, too.
42 </p>
43 <p>
44 When we speak of free software, we are referring to freedom, not
45 price. Our General Public Licenses are designed to make sure that you
46 have the freedom to distribute copies of free software (and charge for
47 this service if you wish), that you receive source code or can get it
48 if you want it, that you can change the software or use pieces of it
49 in new free programs; and that you know you can do these things.
50 </p>
51 <p>
52 To protect your rights, we need to make restrictions that forbid
53 anyone to deny you these rights or to ask you to surrender the rights.
54 These restrictions translate to certain responsibilities for you if you
55 distribute copies of the software, or if you modify it.
56 </p>
57 <p>
58 For example, if you distribute copies of such a program, whether
59 gratis or for a fee, you must give the recipients all the rights that
60 you have. You must make sure that they, too, receive or can get the
61 source code. And you must show them these terms so they know their
62 rights.
63 </p>
64 <p>
65 We protect your rights with two steps: (1) copyright the software, and
66 (2) offer you this license which gives you legal permission to copy,
67 distribute and/or modify the software.
68 </p>
69 <p>
70 Also, for each author's protection and ours, we want to make certain
71 that everyone understands that there is no warranty for this free
72 software. If the software is modified by someone else and passed on, we
73 want its recipients to know that what they have is not the original, so
74 that any problems introduced by others will not reflect on the original
75 authors' reputations.
76 </p>
77 <p>
78 Finally, any free program is threatened constantly by software
79 patents. We wish to avoid the danger that redistributors of a free
80 program will individually obtain patent licenses, in effect making the
81 program proprietary. To prevent this, we have made it clear that any
82 patent must be licensed for everyone's free use or not licensed at all.
83 </p>
84 <p>
85 The precise terms and conditions for copying, distribution and
86 modification follow.
87 </p>
88 <h3>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</h3>
89 <p>
90 <strong>0.</strong>
91 This License applies to any program or other work which contains
92 a notice placed by the copyright holder saying it may be distributed
93 under the terms of this General Public License. The "Program", below,
94 refers to any such program or work, and a "work based on the Program"
95 means either the Program or any derivative work under copyright law:
96 that is to say, a work containing the Program or a portion of it,
97 either verbatim or with modifications and/or translated into another
98 language. (Hereinafter, translation is included without limitation in
99 the term "modification".) Each licensee is addressed as "you".
100 </p>
101 <p>
102 Activities other than copying, distribution and modification are not
103 covered by this License; they are outside its scope. The act of
104 running the Program is not restricted, and the output from the Program
105 is covered only if its contents constitute a work based on the
106 Program (independent of having been made by running the Program).
107 Whether that is true depends on what the Program does.
108 </p>
109 <p>
110 <strong>1.</strong>
111 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 </p>
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 </p>
123 <p>
124 <strong>2.</strong>
125 You may modify your copy or copies of the Program or any portion
126 of it, thus forming a work based on the Program, and copy and
127 distribute such modifications or work under the terms of Section 1
128 above, provided that you also meet all of these conditions:
129 </p>
130 <dl>
131 <dt></dt>
132 <dd>
133 <strong>a)</strong>
134 You must cause the modified files to carry prominent notices
135 stating that you changed the files and the date of any change.
136 </dd>
137 <dt></dt>
138 <dd>
139 <strong>b)</strong>
140 You must cause any work that you distribute or publish, that in
141 whole or in part contains or is derived from the Program or any
142 part thereof, to be licensed as a whole at no charge to all third
143 parties under the terms of this License.
144 </dd>
145 <dt></dt>
146 <dd>
147 <strong>c)</strong>
148 If the modified program normally reads commands interactively
149 when run, you must cause it, when started running for such
150 interactive use in the most ordinary way, to print or display an
151 announcement including an appropriate copyright notice and a
152 notice that there is no warranty (or else, saying that you provide
153 a warranty) and that users may redistribute the program under
154 these conditions, and telling the user how to view a copy of this
155 License. (Exception: if the Program itself is interactive but
156 does not normally print such an announcement, your work based on
157 the Program is not required to print an announcement.)
158 </dd>
159 </dl>
160 <p>
161 These requirements apply to the modified work as a whole. If
162 identifiable sections of that work are not derived from the Program,
163 and can be reasonably considered independent and separate works in
164 themselves, then this License, and its terms, do not apply to those
165 sections when you distribute them as separate works. But when you
166 distribute the same sections as part of a whole which is a work based
167 on the Program, the distribution of the whole must be on the terms of
168 this License, whose permissions for other licensees extend to the
169 entire whole, and thus to each and every part regardless of who wrote it.
170 </p>
171 <p>
172 Thus, it is not the intent of this section to claim rights or contest
173 your rights to work written entirely by you; rather, the intent is to
174 exercise the right to control the distribution of derivative or
175 collective works based on the Program.
176 </p>
177 <p>
178 In addition, mere aggregation of another work not based on the Program
179 with the Program (or with a work based on the Program) on a volume of
180 a storage or distribution medium does not bring the other work under
181 the scope of this License.
182 </p>
183 <p>
184 <strong>3.</strong>
185 You may copy and distribute the Program (or a work based on it,
186 under Section 2) in object code or executable form under the terms of
187 Sections 1 and 2 above provided that you also do one of the following:
188 </p>
189
190 <!-- we use this doubled UL to get the sub-sections indented, -->
191 <!-- while making the bullets as unobvious as possible. -->
192 <dl>
193 <dt></dt>
194 <dd>
195 <strong>a)</strong>
196 Accompany it with the complete corresponding machine-readable
197 source code, which must be distributed under the terms of Sections
198 1 and 2 above on a medium customarily used for software interchange; or,
199 </dd>
200 <dt></dt>
201 <dd>
202 <strong>b)</strong>
203 Accompany it with a written offer, valid for at least three
204 years, to give any third party, for a charge no more than your
205 cost of physically performing source distribution, a complete
206 machine-readable copy of the corresponding source code, to be
207 distributed under the terms of Sections 1 and 2 above on a medium
208 customarily used for software interchange; or,
209 </dd>
210 <dt></dt>
211 <dd>
212 <strong>c)</strong>
213 Accompany it with the information you received as to the offer
214 to distribute corresponding source code. (This alternative is
215 allowed only for noncommercial distribution and only if you
216 received the program in object code or executable form with such
217 an offer, in accord with Subsection b above.)
218 </dd>
219 </dl>
220 <p>
221 The source code for a work means the preferred form of the work for
222 making modifications to it. For an executable work, complete source
223 code means all the source code for all modules it contains, plus any
224 associated interface definition files, plus the scripts used to
225 control compilation and installation of the executable. However, as a
226 special exception, the source code distributed need not include
227 anything that is normally distributed (in either source or binary
228 form) with the major components (compiler, kernel, and so on) of the
229 operating system on which the executable runs, unless that component
230 itself accompanies the executable.
231 </p>
232 <p>
233 If distribution of executable or object code is made by offering
234 access to copy from a designated place, then offering equivalent
235 access to copy the source code from the same place counts as
236 distribution of the source code, even though third parties are not
237 compelled to copy the source along with the object code.
238 </p>
239 <p>
240 <strong>4.</strong>
241 You may not copy, modify, sublicense, or distribute the Program
242 except as expressly provided under this License. Any attempt
243 otherwise to copy, modify, sublicense or distribute the Program is
244 void, and will automatically terminate your rights under this License.
245 However, parties who have received copies, or rights, from you under
246 this License will not have their licenses terminated so long as such
247 parties remain in full compliance.
248 </p>
249 <p>
250 <strong>5.</strong>
251 You are not required to accept this License, since you have not
252 signed it. However, nothing else grants you permission to modify or
253 distribute the Program or its derivative works. These actions are
254 prohibited by law if you do not accept this License. Therefore, by
255 modifying or distributing the Program (or any work based on the
256 Program), you indicate your acceptance of this License to do so, and
257 all its terms and conditions for copying, distributing or modifying
258 the Program or works based on it.
259 </p>
260 <p>
261 <strong>6.</strong>
262 Each time you redistribute the Program (or any work based on the
263 Program), the recipient automatically receives a license from the
264 original licensor to copy, distribute or modify the Program subject to
265 these terms and conditions. You may not impose any further
266 restrictions on the recipients' exercise of the rights granted herein.
267 You are not responsible for enforcing compliance by third parties to
268 this License.
269 </p>
270 <p>
271 <strong>7.</strong>
272 If, as a consequence of a court judgment or allegation of patent
273 infringement or for any other reason (not limited to patent issues),
274 conditions are imposed on you (whether by court order, agreement or
275 otherwise) that contradict the conditions of this License, they do not
276 excuse you from the conditions of this License. If you cannot
277 distribute so as to satisfy simultaneously your obligations under this
278 License and any other pertinent obligations, then as a consequence you
279 may not distribute the Program at all. For example, if a patent
280 license would not permit royalty-free redistribution of the Program by
281 all those who receive copies directly or indirectly through you, then
282 the only way you could satisfy both it and this License would be to
283 refrain entirely from distribution of the Program.
284 </p>
285 <p>
286 If any portion of this section is held invalid or unenforceable under
287 any particular circumstance, the balance of the section is intended to
288 apply and the section as a whole is intended to apply in other
289 circumstances.
290 </p>
291 <p>
292 It is not the purpose of this section to induce you to infringe any
293 patents or other property right claims or to contest validity of any
294 such claims; this section has the sole purpose of protecting the
295 integrity of the free software distribution system, which is
296 implemented by public license practices. Many people have made
297 generous contributions to the wide range of software distributed
298 through that system in reliance on consistent application of that
299 system; it is up to the author/donor to decide if he or she is willing
300 to distribute software through any other system and a licensee cannot
301 impose that choice.
302 </p>
303 <p>
304 This section is intended to make thoroughly clear what is believed to
305 be a consequence of the rest of this License.
306 </p>
307 <p>
308 <strong>8.</strong>
309 If the distribution and/or use of the Program is restricted in
310 certain countries either by patents or by copyrighted interfaces, the
311 original copyright holder who places the Program under this License
312 may add an explicit geographical distribution limitation excluding
313 those countries, so that distribution is permitted only in or among
314 countries not thus excluded. In such case, this License incorporates
315 the limitation as if written in the body of this License.
316 </p>
317 <p>
318 <strong>9.</strong>
319 The Free Software Foundation may publish revised and/or new versions
320 of the General Public License from time to time. Such new versions will
321 be similar in spirit to the present version, but may differ in detail to
322 address new problems or concerns.
323 </p>
324 <p>
325 Each version is given a distinguishing version number. If the Program
326 specifies a version number of this License which applies to it and "any
327 later version", you have the option of following the terms and conditions
328 either of that version or of any later version published by the Free
329 Software Foundation. If the Program does not specify a version number of
330 this License, you may choose any version ever published by the Free Software
331 Foundation.
332 </p>
333 <p>
334 <strong>10.</strong>
335 If you wish to incorporate parts of the Program into other free
336 programs whose distribution conditions are different, write to the author
337 to ask for permission. For software which is copyrighted by the Free
338 Software Foundation, write to the Free Software Foundation; we sometimes
339 make exceptions for this. Our decision will be guided by the two goals
340 of preserving the free status of all derivatives of our free software and
341 of promoting the sharing and reuse of software generally.
342 </p>
343 <p><strong>NO WARRANTY</strong></p>
344 <p>
345 <strong>11.</strong>
346 BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
347 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
348 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
349 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
350 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
351 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
352 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
353 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
354 REPAIR OR CORRECTION.
355 </p>
356 <p>
357 <strong>12.</strong>
358 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
359 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
360 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
361 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
362 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
363 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
364 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
365 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
366 POSSIBILITY OF SUCH DAMAGES.
367 </p>
368 <h3>END OF TERMS AND CONDITIONS</h3>
369 <h3>How to Apply These Terms to Your New Programs</h3>
370 <p>
371 If you develop a new program, and you want it to be of the greatest
372 possible use to the public, the best way to achieve this is to make it
373 free software which everyone can redistribute and change under these terms.
374 </p>
375 <p>
376 To do so, attach the following notices to the program. It is safest
377 to attach them to the start of each source file to most effectively
378 convey the exclusion of warranty; and each file should have at least
379 the "copyright" line and a pointer to where the full notice is found.
380 </p>
381 <blockquote>
382 <p>
383 &#60;one line to give the program's name and an idea of what it does.&#62;<br>
384 Copyright (C) yyyy &#60;name of author&#62;</p>
385 <p>
386 <p>This program is free software; you can redistribute it and/or
387 modify it under the terms of the GNU General Public License
388 as published by the Free Software Foundation; either version 2
389 of the License, or (at your option) any later version.</p>
390
391 <p>This program is distributed in the hope that it will be useful,
392 but WITHOUT ANY WARRANTY; without even the implied warranty of
393 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
394 GNU General Public License for more details.</p>
395
396 <p>You should have received a copy of the GNU General Public License
397 along with this program; if not, write to the Free Software
398 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.</p>
399 </blockquote>
400 <p>
401 Also add information on how to contact you by electronic and paper mail.
402 </p>
403 <p>
404 If the program is interactive, make it output a short notice like this
405 when it starts in an interactive mode:
406 </p>
407
408 <p>
409 Gnomovision version 69, Copyright (C) <var>year</var> <var>name of author</var>
410 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
411 type `show w'. This is free software, and you are welcome
412 to redistribute it under certain conditions; type `show c'
413 for details.
414 </p>
415 <p>
416 The hypothetical commands <samp>`show w'</samp> and <samp>`show c'</samp> should show
417 the appropriate parts of the General Public License. Of course, the
418 commands you use may be called something other than <samp>`show w'</samp> and
419 <samp>`show c'</samp>; they could even be mouse-clicks or menu items--whatever
420 suits your program.
421 </p>
422 <p>
423 You should also get your employer (if you work as a programmer) or your
424 school, if any, to sign a "copyright disclaimer" for the program, if
425 necessary. Here is a sample; alter the names:
426 </p>
427 <blockquote>
428 <p>
429 Yoyodyne, Inc., hereby disclaims all copyright
430 interest in the program `Gnomovision'
431 (which makes passes at compilers) written
432 by James Hacker.</p>
433
434 <p>
435 &#60;signature of Ty Coon&#62;, 1 April 1989
436 Ty Coon, President of Vice
437 </p>
438 </blockquote>
439 <p>
440 This General Public License does not permit incorporating your program into
441 proprietary programs. If your program is a subroutine library, you may
442 consider it more useful to permit linking proprietary applications with the
443 library. If this is what you want to do, use the
444 GNU Lesser General Public License
445 instead of this License.
