72 | \gplsec{Preamble} |
73 | |
74 | The licenses for most software are designed to take away your freedom to |
75 | share and change it. By contrast, the GNU General Public License is intended |
76 | to guarantee your freedom to share and change free software---to make sure |
77 | the software is free for all its users. This General Public License applies |
78 | to most of the Free Software Foundation's software and to any other program |
79 | whose authors commit to using it. (Some other Free Software Foundation |
80 | software is covered by the GNU Library General Public License instead.) You |
81 | can apply it to your programs, too. |
82 | |
83 | When we speak of free software, we are referring to freedom, not price. Our |
84 | General Public Licenses are designed to make sure that you have the freedom |
85 | to distribute copies of free software (and charge for this service if you |
86 | wish), that you receive source code or can get it if you want it, that you |
87 | can change the software or use pieces of it in new free programs; and that |
88 | you know you can do these things. |
89 | |
90 | To protect your rights, we need to make restrictions that forbid anyone to |
91 | deny you these rights or to ask you to surrender the rights. These |
92 | restrictions translate to certain responsibilities for you if you distribute |
93 | copies of the software, or if you modify it. |
94 | |
95 | For example, if you distribute copies of such a program, whether gratis or |
96 | for a fee, you must give the recipients all the rights that you have. You |
97 | must make sure that they, too, receive or can get the source code. And you |
98 | must show them these terms so they know their rights. |
99 | |
100 | We protect your rights with two steps: (1) copyright the software, and (2) |
101 | offer you this license which gives you legal permission to copy, distribute |
102 | and/or modify the software. |
103 | |
104 | Also, for each author's protection and ours, we want to make certain that |
105 | everyone understands that there is no warranty for this free software. If |
106 | the software is modified by someone else and passed on, we want its |
107 | recipients to know that what they have is not the original, so that any |
108 | problems introduced by others will not reflect on the original authors' |
109 | reputations. |
110 | |
111 | Finally, any free program is threatened constantly by software patents. We |
112 | wish to avoid the danger that redistributors of a free program will |
113 | individually obtain patent licenses, in effect making the program |
114 | proprietary. To prevent this, we have made it clear that any patent must be |
115 | licensed for everyone's free use or not licensed at all. |
116 | |
117 | The precise terms and conditions for copying, distribution and modification |
118 | follow. |
119 | |
120 | |
121 | \gplsec{Terms and conditions for copying, distribution and modification} |
122 | |
123 | \begin{enumerate} |
124 | |
125 | \makeatletter \setcounter{\@listctr}{-1} \makeatother |
126 | |
127 | \item [0.] This License applies to any program or other work which contains a |
128 | notice placed by the copyright holder saying it may be distributed |
129 | under the terms of this General Public License. The ``Program'', |
130 | below, refers to any such program or work, and a ``work based on the |
131 | Program'' means either the Program or any derivative work under |
132 | copyright law: that is to say, a work containing the Program or a |
133 | portion of it, either verbatim or with modifications and/or translated |
134 | into another language. (Hereinafter, translation is included without |
135 | limitation in the term ``modification''.) Each licensee is addressed |
136 | as ``you''. |
137 | |
138 | Activities other than copying, distribution and modification are not |
139 | covered by this License; they are outside its scope. The act of |
140 | running the Program is not restricted, and the output from the Program |
141 | is covered only if its contents constitute a work based on the Program |
142 | (independent of having been made by running the Program). Whether that |
143 | is true depends on what the Program does. |
144 | |
145 | \item [1.] You may copy and distribute verbatim copies of the Program's |
146 | source code as you receive it, in any medium, provided that you |
147 | conspicuously and appropriately publish on each copy an appropriate |
148 | copyright notice and disclaimer of warranty; keep intact all the |
149 | notices that refer to this License and to the absence of any warranty; |
150 | and give any other recipients of the Program a copy of this License |
151 | along with the Program. |
152 | |
153 | You may charge a fee for the physical act of transferring a copy, and |
154 | you may at your option offer warranty protection in exchange for a fee. |
155 | |
156 | \item [2.] You may modify your copy or copies of the Program or any portion |
157 | of it, thus forming a work based on the Program, and copy and |
158 | distribute such modifications or work under the terms of Section 1 |
159 | above, provided that you also meet all of these conditions: |
160 | |
161 | \begin{enumerate} |
162 | |
163 | \item [(a)] You must cause the modified files to carry prominent |
164 | notices stating that you changed the files and the date of any |
165 | change. |
166 | |
167 | \item [(b)] You must cause any work that you distribute or publish, |
168 | that in whole or in part contains or is derived from the Program |
169 | or any part thereof, to be licensed as a whole at no charge to |
170 | all third parties under the terms of this License. |
171 | |
172 | \item [(c)] If the modified program normally reads commands |
173 | interactively when run, you must cause it, when started running |
174 | for such interactive use in the most ordinary way, to print or |
175 | display an announcement including an appropriate copyright notice |
176 | and a notice that there is no warranty (or else, saying that you |
177 | provide a warranty) and that users may redistribute the program |
178 | under these conditions, and telling the user how to view a copy |
179 | of this License. (Exception: if the Program itself is |
180 | interactive but does not normally print such an announcement, |
181 | your work based on the Program is not required to print an |
182 | announcement.) |
183 | |
184 | \end{enumerate} |
185 | |
186 | These requirements apply to the modified work as a whole. If |
187 | identifiable sections of that work are not derived from the Program, |
188 | and can be reasonably considered independent and separate works in |
189 | themselves, then this License, and its terms, do not apply to those |
190 | sections when you distribute them as separate works. But when you |
191 | distribute the same sections as part of a whole which is a work based |
192 | on the Program, the distribution of the whole must be on the terms of |
193 | this License, whose permissions for other licensees extend to the |
194 | entire whole, and thus to each and every part regardless of who wrote |
195 | it. |
196 | |
197 | Thus, it is not the intent of this section to claim rights or contest |
198 | your rights to work written entirely by you; rather, the intent is to |
199 | exercise the right to control the distribution of derivative or |
200 | collective works based on the Program. |
201 | |
202 | In addition, mere aggregation of another work not based on the Program |
203 | with the Program (or with a work based on the Program) on a volume of a |
204 | storage or distribution medium does not bring the other work under the |
205 | scope of this License. |
206 | |
207 | \item [3.] You may copy and distribute the Program (or a work based on it, |
208 | under Section 2) in object code or executable form under the terms of |
209 | Sections 1 and 2 above provided that you also do one of the following: |
210 | |
211 | \begin{enumerate} |
212 | |
213 | \item [(a)] Accompany it with the complete corresponding |
214 | machine-readable source code, which must be distributed under the |
215 | terms of Sections 1 and 2 above on a medium customarily used for |
216 | software interchange; or, |
217 | |
218 | \item [(b)] Accompany it with a written offer, valid for at least three |
219 | years, to give any third party, for a charge no more than your |
220 | cost of physically performing source distribution, a complete |
221 | machine-readable copy of the corresponding source code, to be |
222 | distributed under the terms of Sections 1 and 2 above on a medium |
223 | customarily used for software interchange; or, |
224 | |
225 | \item [(c)] Accompany it with the information you received as to the |
226 | offer to distribute corresponding source code. (This alternative |
227 | is allowed only for noncommercial distribution and only if you |
228 | received the program in object code or executable form with such |
229 | an offer, in accord with Subsection b above.) |
230 | |
231 | \end{enumerate} |
232 | |
233 | The source code for a work means the preferred form of the work for |
234 | making modifications to it. For an executable work, complete source |
235 | code means all the source code for all modules it contains, plus any |
236 | associated interface definition files, plus the scripts used to control |
237 | compilation and installation of the executable. However, as a special |
238 | exception, the source code distributed need not include anything that |
239 | is normally distributed (in either source or binary form) with the |
240 | major components (compiler, kernel, and so on) of the operating system |
241 | on which the executable runs, unless that component itself accompanies |
242 | the executable. |
243 | |
244 | If distribution of executable or object code is made by offering access |
245 | to copy from a designated place, then offering equivalent access to |
246 | copy the source code from the same place counts as distribution of the |
247 | source code, even though third parties are not compelled to copy the |
248 | source along with the object code. |
249 | |
250 | \item [4.] You may not copy, modify, sublicense, or distribute the Program |
251 | except as expressly provided under this License. Any attempt otherwise |
252 | to copy, modify, sublicense or distribute the Program is void, and will |
253 | automatically terminate your rights under this License. However, |
254 | parties who have received copies, or rights, from you under this |
255 | License will not have their licenses terminated so long as such parties |
256 | remain in full compliance. |
257 | |
258 | \item [5.] You are not required to accept this License, since you have not |
259 | signed it. However, nothing else grants you permission to modify or |
260 | distribute the Program or its derivative works. These actions are |
261 | prohibited by law if you do not accept this License. Therefore, by |
262 | modifying or distributing the Program (or any work based on the |
263 | Program), you indicate your acceptance of this License to do so, and |
264 | all its terms and conditions for copying, distributing or modifying the |
265 | Program or works based on it. |
266 | |
267 | \item [6.] Each time you redistribute the Program (or any work based on the |
268 | Program), the recipient automatically receives a license from the |
269 | original licensor to copy, distribute or modify the Program subject to |
270 | these terms and conditions. You may not impose any further |
271 | restrictions on the recipients' exercise of the rights granted herein. |
272 | You are not responsible for enforcing compliance by third parties to |
273 | this License. |
274 | |
275 | \item [7.] If, as a consequence of a court judgment or allegation of patent |
276 | infringement or for any other reason (not limited to patent issues), |
277 | conditions are imposed on you (whether by court order, agreement or |
278 | otherwise) that contradict the conditions of this License, they do not |
279 | excuse you from the conditions of this License. If you cannot |
280 | distribute so as to satisfy simultaneously your obligations under this |
281 | License and any other pertinent obligations, then as a consequence you |
282 | may not distribute the Program at all. For example, if a patent |
283 | license would not permit royalty-free redistribution of the Program by |
284 | all those who receive copies directly or indirectly through you, then |
285 | the only way you could satisfy both it and this License would be to |
286 | refrain entirely from distribution of the Program. |
287 | |
288 | If any portion of this section is held invalid or unenforceable under |
289 | any particular circumstance, the balance of the section is intended to |
290 | apply and the section as a whole is intended to apply in other |
291 | circumstances. |
292 | |
293 | It is not the purpose of this section to induce you to infringe any |
294 | patents or other property right claims or to contest validity of any |
295 | such claims; this section has the sole purpose of protecting the |
296 | integrity of the free software distribution system, which is |
297 | implemented by public license practices. Many people have made |
298 | generous contributions to the wide range of software distributed |
299 | through that system in reliance on consistent application of that |
300 | system; it is up to the author/donor to decide if he or she is willing |
301 | to distribute software through any other system and a licensee cannot |
302 | impose that choice. |
303 | |
304 | This section is intended to make thoroughly clear what is believed to |
305 | be a consequence of the rest of this License. |
306 | |
307 | \item [8.] If the distribution and/or use of the Program is restricted in |
308 | certain countries either by patents or by copyrighted interfaces, the |
309 | original copyright holder who places the Program under this License may |
310 | add an explicit geographical distribution limitation excluding those |
311 | countries, so that distribution is permitted only in or among countries |
312 | not thus excluded. In such case, this License incorporates the |
313 | limitation as if written in the body of this License. |
314 | |
315 | \item [9.] The Free Software Foundation may publish revised and/or new |
316 | versions of the General Public License from time to time. Such new |
317 | versions will be similar in spirit to the present version, but may |
318 | differ in detail to address new problems or concerns. |
319 | |
320 | Each version is given a distinguishing version number. If the Program |
321 | specifies a version number of this License which applies to it and |
322 | ``any later version'', you have the option of following the terms and |
323 | conditions either of that version or of any later version published by |
324 | the Free Software Foundation. If the Program does not specify a |
325 | version number of this License, you may choose any version ever |
326 | published by the Free Software Foundation. |
327 | |
328 | \item [10.] If you wish to incorporate parts of the Program into other free |
329 | programs whose distribution conditions are different, write to the |
330 | author to ask for permission. For software which is copyrighted by the |
331 | Free Software Foundation, write to the Free Software Foundation; we |
332 | sometimes make exceptions for this. Our decision will be guided by the |
333 | two goals of preserving the free status of all derivatives of our free |
334 | software and of promoting the sharing and reuse of software generally. |
335 | |
336 | \begin{center} |
337 | NO WARRANTY |
338 | \end{center} |
339 | |
340 | \bfseries |
341 | |
342 | \item [11.] Because the Program is licensed free of charge, there is no |
343 | warranty for the Program, to the extent permitted by applicable law. |
344 | except when otherwise stated in writing the copyright holders and/or |
345 | other parties provide the program ``as is'' without warranty of any |
346 | kind, either expressed or implied, including, but not limited to, the |
347 | implied warranties of merchantability and fitness for a particular |
348 | purpose. The entire risk as to the quality and performance of the |
349 | Program is with you. Should the Program prove defective, you assume |
350 | the cost of all necessary servicing, repair or correction. |
351 | |
352 | \item [12.] In no event unless required by applicable law or agreed to in |
353 | writing will any copyright holder, or any other party who may modify |
354 | and/or redistribute the program as permitted above, be liable to you |
355 | for damages, including any general, special, incidental or |
356 | consequential damages arising out of the use or inability to use the |
357 | program (including but not limited to loss of data or data being |
358 | rendered inaccurate or losses sustained by you or third parties or a |
359 | failure of the Program to operate with any other programs), even if |
360 | such holder or other party has been advised of the possibility of such |
361 | damages. |

370 | \gplsec{Appendix: How to Apply These Terms to Your New Programs} |
371 | |
372 | If you develop a new program, and you want it to be of the greatest possible |
373 | use to the public, the best way to achieve this is to make it free software |
374 | which everyone can redistribute and change under these terms. |
375 | |
376 | To do so, attach the following notices to the program. It is safest to |
377 | attach them to the start of each source file to most effectively convey the |
378 | exclusion of warranty; and each file should have at least the ``copyright'' |
379 | line and a pointer to where the full notice is found. |
380 | |
381 | \begin{verbatim} |
382 | <one line to give the program's name and a brief idea of what it does.> |
383 | Copyright (C) 19yy <name of author> |
384 | |
385 | This program is free software; you can redistribute it and/or modify |
386 | it under the terms of the GNU General Public License as published by |
387 | the Free Software Foundation; either version 2 of the License, or |
388 | (at your option) any later version. |
389 | |
390 | This program is distributed in the hope that it will be useful, |
391 | but WITHOUT ANY WARRANTY; without even the implied warranty of |
392 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
393 | GNU General Public License for more details. |
394 | |
395 | You should have received a copy of the GNU General Public License |
396 | along with this program; if not, write to the Free Software Foundation, |
397 | Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. |
398 | \end{verbatim} |
399 | |
400 | Also add information on how to contact you by electronic and paper mail. |
401 | |
402 | If the program is interactive, make it output a short notice like this when |
403 | it starts in an interactive mode: |
404 | |
405 | \begin{verbatim} |
406 | Gnomovision version 69, Copyright (C) 19yy name of author |
407 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type |
408 | `show w'. |
409 | This is free software, and you are welcome to redistribute it |
410 | under certain conditions; type `show c' for details. |
411 | \end{verbatim} |
412 | |
413 | The hypothetical commands `show w' and `show c' should show the appropriate |
414 | parts of the General Public License. Of course, the commands you use may be |
415 | called something other than `show w' and `show c'; they could even be |
416 | mouse-clicks or menu items--whatever suits your program. |
417 | |
418 | You should also get your employer (if you work as a programmer) or your |
419 | school, if any, to sign a ``copyright disclaimer'' for the program, if |
420 | necessary. Here is a sample; alter the names: |
421 | |
422 | \begin{verbatim} |
423 | Yoyodyne, Inc., hereby disclaims all copyright interest in the program |
424 | `Gnomovision' (which makes passes at compilers) written by James Hacker. |
425 | |
426 | <signature of Ty Coon>, 1 April 1989 |
427 | Ty Coon, President of Vice |
428 | \end{verbatim} |
429 | |
430 | This General Public License does not permit incorporating your program into |
431 | proprietary programs. If your program is a subroutine library, you may |
432 | consider it more useful to permit linking proprietary applications with the |
433 | library. If this is what you want to do, use the GNU Library General Public |
434 | License instead of this License. |
435 | |
