|
22 Everyone is permitted to copy and distribute verbatim copies |
|
23 of this license document, but changing it is not allowed. |
|
24 |
|
25 Preamble |
|
26 |
|
27 The licenses for most software are designed to take away your |
|
28 freedom to share and change it. By contrast, the GNU General Public |
|
29 License is intended to guarantee your freedom to share and change free |
|
30 software--to make sure the software is free for all its users. This |
|
31 General Public License applies to most of the Free Software |
|
32 Foundation's software and to any other program whose authors commit to |
|
33 using it. (Some other Free Software Foundation software is covered by |
|
34 the GNU Library General Public License instead.) You can apply it to |
|
35 your programs, too. |
|
36 |
|
37 When we speak of free software, we are referring to freedom, not |
|
38 price. Our General Public Licenses are designed to make sure that you |
|
39 have the freedom to distribute copies of free software (and charge for |
|
40 this service if you wish), that you receive source code or can get it |
|
41 if you want it, that you can change the software or use pieces of it |
|
42 in new free programs; and that you know you can do these things. |
|
43 |
|
44 To protect your rights, we need to make restrictions that forbid |
|
45 anyone to deny you these rights or to ask you to surrender the rights. |
|
46 These restrictions translate to certain responsibilities for you if you |
|
47 distribute copies of the software, or if you modify it. |
|
48 |
|
49 For example, if you distribute copies of such a program, whether |
|
50 gratis or for a fee, you must give the recipients all the rights that |
|
51 you have. You must make sure that they, too, receive or can get the |
|
52 source code. And you must show them these terms so they know their |
|
53 rights. |
|
54 |
|
55 We protect your rights with two steps: (1) copyright the software, and |
|
56 (2) offer you this license which gives you legal permission to copy, |
|
57 distribute and/or modify the software. |
|
58 |
|
59 Also, for each author's protection and ours, we want to make certain |
|
60 that everyone understands that there is no warranty for this free |
|
61 software. If the software is modified by someone else and passed on, we |
|
62 want its recipients to know that what they have is not the original, so |
|
63 that any problems introduced by others will not reflect on the original |
|
64 authors' reputations. |
|
65 |
|
66 Finally, any free program is threatened constantly by software |
|
67 patents. We wish to avoid the danger that redistributors of a free |
|
68 program will individually obtain patent licenses, in effect making the |
|
69 program proprietary. To prevent this, we have made it clear that any |
|
70 patent must be licensed for everyone's free use or not licensed at all. |
|
71 |
|
72 The precise terms and conditions for copying, distribution and |
|
73 modification follow. |
|
74 |
|
75 GNU GENERAL PUBLIC LICENSE |
|
76 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
|
77 |
|
78 0. This License applies to any program or other work which contains |
|
79 a notice placed by the copyright holder saying it may be distributed |
|
80 under the terms of this General Public License. The "Program", below, |
|
81 refers to any such program or work, and a "work based on the Program" |
|
82 means either the Program or any derivative work under copyright law: |
|
83 that is to say, a work containing the Program or a portion of it, |
|
84 either verbatim or with modifications and/or translated into another |
|
85 language. (Hereinafter, translation is included without limitation in |
|
86 the term "modification".) Each licensee is addressed as "you". |
|
87 |
|
88 Activities other than copying, distribution and modification are not |
|
89 covered by this License; they are outside its scope. The act of |
|
90 running the Program is not restricted, and the output from the Program |
|
91 is covered only if its contents constitute a work based on the |
|
92 Program (independent of having been made by running the Program). |
|
93 Whether that is true depends on what the Program does. |
|
94 |
|
95 1. You may copy and distribute verbatim copies of the Program's |
|
96 source code as you receive it, in any medium, provided that you |
|
97 conspicuously and appropriately publish on each copy an appropriate |
|
98 copyright notice and disclaimer of warranty; keep intact all the |
|
99 notices that refer to this License and to the absence of any warranty; |
|
100 and give any other recipients of the Program a copy of this License |
|
101 along with the Program. |
|
102 |
|
103 You may charge a fee for the physical act of transferring a copy, and |
|
104 you may at your option offer warranty protection in exchange for a fee. |
|
105 |
|
106 2. You may modify your copy or copies of the Program or any portion |
|
107 of it, thus forming a work based on the Program, and copy and |
|
108 distribute such modifications or work under the terms of Section 1 |
|
109 above, provided that you also meet all of these conditions: |
|
110 |
|
111 a) You must cause the modified files to carry prominent notices |
|
112 stating that you changed the files and the date of any change. |
|
113 |
|
114 b) You must cause any work that you distribute or publish, that in |
|
115 whole or in part contains or is derived from the Program or any |
|
116 part thereof, to be licensed as a whole at no charge to all third |
|
117 parties under the terms of this License. |
|
118 |
|
119 c) If the modified program normally reads commands interactively |
|
120 when run, you must cause it, when started running for such |
|
121 interactive use in the most ordinary way, to print or display an |
|
122 announcement including an appropriate copyright notice and a |
|
123 notice that there is no warranty (or else, saying that you provide |
|
124 a warranty) and that users may redistribute the program under |
|
125 these conditions, and telling the user how to view a copy of this |
|
126 License. (Exception: if the Program itself is interactive but |
|
127 does not normally print such an announcement, your work based on |
|
128 the Program is not required to print an announcement.) |
|
129 |
|
130 These requirements apply to the modified work as a whole. If |
|
131 identifiable sections of that work are not derived from the Program, |
|
132 and can be reasonably considered independent and separate works in |
|
133 themselves, then this License, and its terms, do not apply to those |
|
134 sections when you distribute them as separate works. But when you |
|
135 distribute the same sections as part of a whole which is a work based |
|
136 on the Program, the distribution of the whole must be on the terms of |
|
137 this License, whose permissions for other licensees extend to the |
|
138 entire whole, and thus to each and every part regardless of who wrote it. |
|
139 |
|
140 Thus, it is not the intent of this section to claim rights or contest |
|
141 your rights to work written entirely by you; rather, the intent is to |
|
142 exercise the right to control the distribution of derivative or |
|
143 collective works based on the Program. |
|
144 |
|
145 In addition, mere aggregation of another work not based on the Program |
|
146 with the Program (or with a work based on the Program) on a volume of |
|
147 a storage or distribution medium does not bring the other work under |
|
148 the scope of this License. |
|
149 |
|
150 3. You may copy and distribute the Program (or a work based on it, |
|
151 under Section 2) in object code or executable form under the terms of |
|
152 Sections 1 and 2 above provided that you also do one of the following: |
|
153 |
|
154 a) Accompany it with the complete corresponding machine-readable |
|
155 source code, which must be distributed under the terms of Sections |
|
156 1 and 2 above on a medium customarily used for software interchange; or, |
|
157 |
|
158 b) Accompany it with a written offer, valid for at least three |
|
159 years, to give any third party, for a charge no more than your |
|
160 cost of physically performing source distribution, a complete |
|
161 machine-readable copy of the corresponding source code, to be |
|
162 distributed under the terms of Sections 1 and 2 above on a medium |
|
163 customarily used for software interchange; or, |
|
164 |
|
165 c) Accompany it with the information you received as to the offer |
|
166 to distribute corresponding source code. (This alternative is |
|
167 allowed only for noncommercial distribution and only if you |
|
168 received the program in object code or executable form with such |
|
169 an offer, in accord with Subsection b above.) |
|
170 |
|
171 The source code for a work means the preferred form of the work for |
|
172 making modifications to it. For an executable work, complete source |
|
173 code means all the source code for all modules it contains, plus any |
|
174 associated interface definition files, plus the scripts used to |
|
175 control compilation and installation of the executable. However, as a |
|
176 special exception, the source code distributed need not include |
|
177 anything that is normally distributed (in either source or binary |
|
178 form) with the major components (compiler, kernel, and so on) of the |
|
179 operating system on which the executable runs, unless that component |
|
180 itself accompanies the executable. |
|
181 |
|
182 If distribution of executable or object code is made by offering |
|
183 access to copy from a designated place, then offering equivalent |
|
184 access to copy the source code from the same place counts as |
|
185 distribution of the source code, even though third parties are not |
|
186 compelled to copy the source along with the object code. |
|
187 |
|
188 4. You may not copy, modify, sublicense, or distribute the Program |
|
189 except as expressly provided under this License. Any attempt |
|
190 otherwise to copy, modify, sublicense or distribute the Program is |
|
191 void, and will automatically terminate your rights under this License. |
|
192 However, parties who have received copies, or rights, from you under |
|
193 this License will not have their licenses terminated so long as such |
|
194 parties remain in full compliance. |
|
195 |
|
196 5. You are not required to accept this License, since you have not |
|
197 signed it. However, nothing else grants you permission to modify or |
|
198 distribute the Program or its derivative works. These actions are |
|
199 prohibited by law if you do not accept this License. Therefore, by |
|
200 modifying or distributing the Program (or any work based on the |
|
201 Program), you indicate your acceptance of this License to do so, and |
|
202 all its terms and conditions for copying, distributing or modifying |
|
203 the Program or works based on it. |
|
204 |
|
205 6. Each time you redistribute the Program (or any work based on the |
|
206 Program), the recipient automatically receives a license from the |
|
207 original licensor to copy, distribute or modify the Program subject to |
|
208 these terms and conditions. You may not impose any further |
|
209 restrictions on the recipients' exercise of the rights granted herein. |
|
210 You are not responsible for enforcing compliance by third parties to |
|
211 this License. |
|
212 |
|
213 7. If, as a consequence of a court judgment or allegation of patent |
|
214 infringement or for any other reason (not limited to patent issues), |
|
215 conditions are imposed on you (whether by court order, agreement or |
|
216 otherwise) that contradict the conditions of this License, they do not |
|
217 excuse you from the conditions of this License. If you cannot |
|
218 distribute so as to satisfy simultaneously your obligations under this |
|
219 License and any other pertinent obligations, then as a consequence you |
|
220 may not distribute the Program at all. For example, if a patent |
|
221 license would not permit royalty-free redistribution of the Program by |
|
222 all those who receive copies directly or indirectly through you, then |
|
223 the only way you could satisfy both it and this License would be to |
|
224 refrain entirely from distribution of the Program. |
|
225 |
|
226 If any portion of this section is held invalid or unenforceable under |
|
227 any particular circumstance, the balance of the section is intended to |
|
228 apply and the section as a whole is intended to apply in other |
|
229 circumstances. |
|
230 |
|
231 It is not the purpose of this section to induce you to infringe any |
|
232 patents or other property right claims or to contest validity of any |
|
233 such claims; this section has the sole purpose of protecting the |
|
234 integrity of the free software distribution system, which is |
|
235 implemented by public license practices. Many people have made |
|
236 generous contributions to the wide range of software distributed |
|
237 through that system in reliance on consistent application of that |
|
238 system; it is up to the author/donor to decide if he or she is willing |
|
239 to distribute software through any other system and a licensee cannot |
|
240 impose that choice. |
|
241 |
|
242 This section is intended to make thoroughly clear what is believed to |
|
243 be a consequence of the rest of this License. |
|
244 |
|
245 8. If the distribution and/or use of the Program is restricted in |
|
246 certain countries either by patents or by copyrighted interfaces, the |
|
247 original copyright holder who places the Program under this License |
|
248 may add an explicit geographical distribution limitation excluding |
|
249 those countries, so that distribution is permitted only in or among |
|
250 countries not thus excluded. In such case, this License incorporates |
|
251 the limitation as if written in the body of this License. |
|
252 |
|
253 9. The Free Software Foundation may publish revised and/or new versions |
|
254 of the General Public License from time to time. Such new versions will |
|
255 be similar in spirit to the present version, but may differ in detail to |
|
256 address new problems or concerns. |
|
257 |
|
258 Each version is given a distinguishing version number. If the Program |
|
259 specifies a version number of this License which applies to it and "any |
|
260 later version", you have the option of following the terms and conditions |
|
261 either of that version or of any later version published by the Free |
|
262 Software Foundation. If the Program does not specify a version number of |
|
263 this License, you may choose any version ever published by the Free Software |
|
264 Foundation. |
|
265 |
|
266 10. If you wish to incorporate parts of the Program into other free |
|
267 programs whose distribution conditions are different, write to the author |
|
268 to ask for permission. For software which is copyrighted by the Free |
|
269 Software Foundation, write to the Free Software Foundation; we sometimes |
|
270 make exceptions for this. Our decision will be guided by the two goals |
|
271 of preserving the free status of all derivatives of our free software and |
|
272 of promoting the sharing and reuse of software generally. |
|
273 |
|
274 NO WARRANTY |
|
275 |
|
276 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
|
277 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |
|
278 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
|
279 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |
|
280 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
|
281 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
|
282 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
|
283 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
|
284 REPAIR OR CORRECTION. |
|
285 |
|
286 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
|
287 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR |
|
288 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, |
|
289 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING |
|
290 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED |
|
291 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY |
|
292 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER |
|
293 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE |
|
294 POSSIBILITY OF SUCH DAMAGES. |
|
295 |
|
296 END OF TERMS AND CONDITIONS |
|
297 |
|
298 How to Apply These Terms to Your New Programs |
|
299 |
|
300 If you develop a new program, and you want it to be of the greatest |
|
301 possible use to the public, the best way to achieve this is to make it |
|
302 free software which everyone can redistribute and change under these terms. |
|
303 |
|
304 To do so, attach the following notices to the program. It is safest |
|
305 to attach them to the start of each source file to most effectively |
|
306 convey the exclusion of warranty; and each file should have at least |
|
307 the "copyright" line and a pointer to where the full notice is found. |
|
308 |
|
309 <one line to give the program's name and a brief idea of what it does.> |
|
310 Copyright (C) <year> <name of author> |
|
311 |
|
312 This program is free software; you can redistribute it and/or modify |
|
313 it under the terms of the GNU General Public License as published by |
|
314 the Free Software Foundation; either version 2 of the License, or |
|
315 (at your option) any later version. |
|
316 |
|
317 This program is distributed in the hope that it will be useful, |
|
318 but WITHOUT ANY WARRANTY; without even the implied warranty of |
|
319 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
|
320 GNU General Public License for more details. |
|
321 |
|
322 You should have received a copy of the GNU General Public License |
|
323 along with this program; if not, write to the Free Software |
|
324 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA |
|
325 |
|
326 |
|
327 Also add information on how to contact you by electronic and paper mail. |
|
328 |
|
329 If the program is interactive, make it output a short notice like this |
|
330 when it starts in an interactive mode: |
|
331 |
|
332 Gnomovision version 69, Copyright (C) year name of author |
|
333 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
|
334 This is free software, and you are welcome to redistribute it |
|
335 under certain conditions; type `show c' for details. |
|
336 |
|
337 The hypothetical commands `show w' and `show c' should show the appropriate |
|
338 parts of the General Public License. Of course, the commands you use may |
|
339 be called something other than `show w' and `show c'; they could even be |
|
340 mouse-clicks or menu items--whatever suits your program. |
|
341 |
|
342 You should also get your employer (if you work as a programmer) or your |
|
343 school, if any, to sign a "copyright disclaimer" for the program, if |
|
344 necessary. Here is a sample; alter the names: |
|
345 |
|
346 Yoyodyne, Inc., hereby disclaims all copyright interest in the program |
|
347 `Gnomovision' (which makes passes at compilers) written by James Hacker. |

351 |
|
352 This General Public License does not permit incorporating your program into |
|
353 proprietary programs. If your program is a subroutine library, you may |
|
354 consider it more useful to permit linking proprietary applications with the |
|
355 library. If this is what you want to do, use the GNU Library General |
|
356 Public License instead of this License. |
