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

334 | ||
335 | This General Public License does not permit incorporating your program into | |
336 | proprietary programs. If your program is a subroutine library, you may | |
337 | consider it more useful to permit linking proprietary applications with the | |
338 | library. If this is what you want to do, use the GNU Library General Public | |
339 | License instead of this License. |
