|

|
14 Everyone is permitted to copy and distribute verbatim copies |
|
15 of this license document, but changing it is not allowed. |
|
16 |
|
17 Preamble |
|
18 |
|
19 The licenses for most software are designed to take away your |
|
20 freedom to share and change it. By contrast, the GNU General Public |
|
21 License is intended to guarantee your freedom to share and change free |
|
22 software--to make sure the software is free for all its users. This |
|
23 General Public License applies to most of the Free Software |
|
24 Foundation's software and to any other program whose authors commit to |
|
25 using it. (Some other Free Software Foundation software is covered by |
|
26 the GNU Library General Public License instead.) You can apply it to |
|
27 your programs, too. |
|
28 |
|
29 When we speak of free software, we are referring to freedom, not |
|
30 price. Our General Public Licenses are designed to make sure that you |
|
31 have the freedom to distribute copies of free software (and charge for |
|
32 this service if you wish), that you receive source code or can get it |
|
33 if you want it, that you can change the software or use pieces of it |
|
34 in new free programs; and that you know you can do these things. |
|
35 |
|
36 To protect your rights, we need to make restrictions that forbid |
|
37 anyone to deny you these rights or to ask you to surrender the rights. |
|
38 These restrictions translate to certain responsibilities for you if you |
|
39 distribute copies of the software, or if you modify it. |
|
40 |
|
41 For example, if you distribute copies of such a program, whether |
|
42 gratis or for a fee, you must give the recipients all the rights that |
|
43 you have. You must make sure that they, too, receive or can get the |
|
44 source code. And you must show them these terms so they know their |
|
45 rights. |
|
46 |
|
47 We protect your rights with two steps: (1) copyright the software, and |
|
48 (2) offer you this license which gives you legal permission to copy, |
|
49 distribute and/or modify the software. |
|
50 |
|
51 Also, for each author's protection and ours, we want to make certain |
|
52 that everyone understands that there is no warranty for this free |
|
53 software. If the software is modified by someone else and passed on, we |
|
54 want its recipients to know that what they have is not the original, so |
|
55 that any problems introduced by others will not reflect on the original |
|
56 authors' reputations. |
|
57 |
|
58 Finally, any free program is threatened constantly by software |
|
59 patents. We wish to avoid the danger that redistributors of a free |
|
60 program will individually obtain patent licenses, in effect making the |
|
61 program proprietary. To prevent this, we have made it clear that any |
|
62 patent must be licensed for everyone's free use or not licensed at all. |
|
63 |
|
64 The precise terms and conditions for copying, distribution and |
|
65 modification follow. |
|
66 |
|
67 GNU GENERAL PUBLIC LICENSE |
|
68 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
|
69 |
|
70 0. This License applies to any program or other work which contains |
|
71 a notice placed by the copyright holder saying it may be distributed |
|
72 under the terms of this General Public License. The "Program", below, |
|
73 refers to any such program or work, and a "work based on the Program" |
|
74 means either the Program or any derivative work under copyright law: |
|
75 that is to say, a work containing the Program or a portion of it, |
|
76 either verbatim or with modifications and/or translated into another |
|
77 language. (Hereinafter, translation is included without limitation in |
|
78 the term "modification".) Each licensee is addressed as "you". |
|
79 |
|
80 Activities other than copying, distribution and modification are not |
|
81 covered by this License; they are outside its scope. The act of |
|
82 running the Program is not restricted, and the output from the Program |
|
83 is covered only if its contents constitute a work based on the |
|
84 Program (independent of having been made by running the Program). |
|
85 Whether that is true depends on what the Program does. |
|
86 |
|
87 1. You may copy and distribute verbatim copies of the Program's |
|
88 source code as you receive it, in any medium, provided that you |
|
89 conspicuously and appropriately publish on each copy an appropriate |
|
90 copyright notice and disclaimer of warranty; keep intact all the |
|
91 notices that refer to this License and to the absence of any warranty; |
|
92 and give any other recipients of the Program a copy of this License |
|
93 along with the Program. |
|
94 |
|
95 You may charge a fee for the physical act of transferring a copy, and |
|
96 you may at your option offer warranty protection in exchange for a fee. |
|
97 |
|
98 2. You may modify your copy or copies of the Program or any portion |
|
99 of it, thus forming a work based on the Program, and copy and |
|
100 distribute such modifications or work under the terms of Section 1 |
|
101 above, provided that you also meet all of these conditions: |
|
102 |
|
103 a) You must cause the modified files to carry prominent notices |
|
104 stating that you changed the files and the date of any change. |
|
105 |
|
106 b) You must cause any work that you distribute or publish, that in |
|
107 whole or in part contains or is derived from the Program or any |
|
108 part thereof, to be licensed as a whole at no charge to all third |
|
109 parties under the terms of this License. |
|
110 |
|
111 c) If the modified program normally reads commands interactively |
|
112 when run, you must cause it, when started running for such |
|
113 interactive use in the most ordinary way, to print or display an |
|
114 announcement including an appropriate copyright notice and a |
|
115 notice that there is no warranty (or else, saying that you provide |
|
116 a warranty) and that users may redistribute the program under |
|
117 these conditions, and telling the user how to view a copy of this |
|
118 License. (Exception: if the Program itself is interactive but |
|
119 does not normally print such an announcement, your work based on |
|
120 the Program is not required to print an announcement.) |
|
121 |
|
122 These requirements apply to the modified work as a whole. If |
|
123 identifiable sections of that work are not derived from the Program, |
|
124 and can be reasonably considered independent and separate works in |
|
125 themselves, then this License, and its terms, do not apply to those |
|
126 sections when you distribute them as separate works. But when you |
|
127 distribute the same sections as part of a whole which is a work based |
|
128 on the Program, the distribution of the whole must be on the terms of |
|
129 this License, whose permissions for other licensees extend to the |
|
130 entire whole, and thus to each and every part regardless of who wrote it. |
|
131 |
|
132 Thus, it is not the intent of this section to claim rights or contest |
|
133 your rights to work written entirely by you; rather, the intent is to |
|
134 exercise the right to control the distribution of derivative or |
|
135 collective works based on the Program. |
|
136 |
|
137 In addition, mere aggregation of another work not based on the Program |
|
138 with the Program (or with a work based on the Program) on a volume of |
|
139 a storage or distribution medium does not bring the other work under |
|
140 the scope of this License. |
|
141 |
|
142 3. You may copy and distribute the Program (or a work based on it, |
|
143 under Section 2) in object code or executable form under the terms of |
|
144 Sections 1 and 2 above provided that you also do one of the following: |
|
145 |
|
146 a) Accompany it with the complete corresponding machine-readable |
|
147 source code, which must be distributed under the terms of Sections |
|
148 1 and 2 above on a medium customarily used for software interchange; or, |
|
149 |
|
150 b) Accompany it with a written offer, valid for at least three |
|
151 years, to give any third party, for a charge no more than your |
|
152 cost of physically performing source distribution, a complete |
|
153 machine-readable copy of the corresponding source code, to be |
|
154 distributed under the terms of Sections 1 and 2 above on a medium |
|
155 customarily used for software interchange; or, |
|
156 |
|
157 c) Accompany it with the information you received as to the offer |
|
158 to distribute corresponding source code. (This alternative is |
|
159 allowed only for noncommercial distribution and only if you |
|
160 received the program in object code or executable form with such |
|
161 an offer, in accord with Subsection b above.) |
|
162 |
|
163 The source code for a work means the preferred form of the work for |
|
164 making modifications to it. For an executable work, complete source |
|
165 code means all the source code for all modules it contains, plus any |
|
166 associated interface definition files, plus the scripts used to |
|
167 control compilation and installation of the executable. However, as a |
|
168 special exception, the source code distributed need not include |
|
169 anything that is normally distributed (in either source or binary |
|
170 form) with the major components (compiler, kernel, and so on) of the |
|
171 operating system on which the executable runs, unless that component |
|
172 itself accompanies the executable. |
|
173 |
|
174 If distribution of executable or object code is made by offering |
|
175 access to copy from a designated place, then offering equivalent |
|
176 access to copy the source code from the same place counts as |
|
177 distribution of the source code, even though third parties are not |
|
178 compelled to copy the source along with the object code. |
|
179 |
|
180 4. You may not copy, modify, sublicense, or distribute the Program |
|
181 except as expressly provided under this License. Any attempt |
|
182 otherwise to copy, modify, sublicense or distribute the Program is |
|
183 void, and will automatically terminate your rights under this License. |
|
184 However, parties who have received copies, or rights, from you under |
|
185 this License will not have their licenses terminated so long as such |
|
186 parties remain in full compliance. |
|
187 |
|
188 5. You are not required to accept this License, since you have not |
|
189 signed it. However, nothing else grants you permission to modify or |
|
190 distribute the Program or its derivative works. These actions are |
|
191 prohibited by law if you do not accept this License. Therefore, by |
|
192 modifying or distributing the Program (or any work based on the |
|
193 Program), you indicate your acceptance of this License to do so, and |
|
194 all its terms and conditions for copying, distributing or modifying |
|
195 the Program or works based on it. |
|
196 |
|
197 6. Each time you redistribute the Program (or any work based on the |
|
198 Program), the recipient automatically receives a license from the |
|
199 original licensor to copy, distribute or modify the Program subject to |
|
200 these terms and conditions. You may not impose any further |
|
201 restrictions on the recipients' exercise of the rights granted herein. |
|
202 You are not responsible for enforcing compliance by third parties to |
|
203 this License. |
|
204 |
|
205 7. If, as a consequence of a court judgment or allegation of patent |
|
206 infringement or for any other reason (not limited to patent issues), |
|
207 conditions are imposed on you (whether by court order, agreement or |
|
208 otherwise) that contradict the conditions of this License, they do not |
|
209 excuse you from the conditions of this License. If you cannot |
|
210 distribute so as to satisfy simultaneously your obligations under this |
|
211 License and any other pertinent obligations, then as a consequence you |
|
212 may not distribute the Program at all. For example, if a patent |
|
213 license would not permit royalty-free redistribution of the Program by |
|
214 all those who receive copies directly or indirectly through you, then |
|
215 the only way you could satisfy both it and this License would be to |
|
216 refrain entirely from distribution of the Program. |
|
217 |
|
218 If any portion of this section is held invalid or unenforceable under |
|
219 any particular circumstance, the balance of the section is intended to |
|
220 apply and the section as a whole is intended to apply in other |
|
221 circumstances. |
|
222 |
|
223 It is not the purpose of this section to induce you to infringe any |
|
224 patents or other property right claims or to contest validity of any |
|
225 such claims; this section has the sole purpose of protecting the |
|
226 integrity of the free software distribution system, which is |
|
227 implemented by public license practices. Many people have made |
|
228 generous contributions to the wide range of software distributed |
|
229 through that system in reliance on consistent application of that |
|
230 system; it is up to the author/donor to decide if he or she is willing |
|
231 to distribute software through any other system and a licensee cannot |
|
232 impose that choice. |
|
233 |
|
234 This section is intended to make thoroughly clear what is believed to |
|
235 be a consequence of the rest of this License. |
|
236 |
|
237 8. If the distribution and/or use of the Program is restricted in |
|
238 certain countries either by patents or by copyrighted interfaces, the |
|
239 original copyright holder who places the Program under this License |
|
240 may add an explicit geographical distribution limitation excluding |
|
241 those countries, so that distribution is permitted only in or among |
|
242 countries not thus excluded. In such case, this License incorporates |
|
243 the limitation as if written in the body of this License. |
|
244 |
|
245 9. The Free Software Foundation may publish revised and/or new versions |
|
246 of the General Public License from time to time. Such new versions will |
|
247 be similar in spirit to the present version, but may differ in detail to |
|
248 address new problems or concerns. |
|
249 |
|
250 Each version is given a distinguishing version number. If the Program |
|
251 specifies a version number of this License which applies to it and "any |
|
252 later version", you have the option of following the terms and conditions |
|
253 either of that version or of any later version published by the Free |
|
254 Software Foundation. If the Program does not specify a version number of |
|
255 this License, you may choose any version ever published by the Free Software |
|
256 Foundation. |
|
257 |
|
258 10. If you wish to incorporate parts of the Program into other free |
|
259 programs whose distribution conditions are different, write to the author |
|
260 to ask for permission. For software which is copyrighted by the Free |
|
261 Software Foundation, write to the Free Software Foundation; we sometimes |
|
262 make exceptions for this. Our decision will be guided by the two goals |
|
263 of preserving the free status of all derivatives of our free software and |
|
264 of promoting the sharing and reuse of software generally. |
|
265 |
|
266 NO WARRANTY |
|
267 |
|
268 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
|
269 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |
|
270 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
|
271 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |
|
272 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
|
273 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
|
274 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
|
275 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
|
276 REPAIR OR CORRECTION. |
|
277 |
|
278 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
|
279 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR |
|
280 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, |
|
281 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING |
|
282 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED |
|
283 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY |
|
284 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER |
|
285 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE |
|
286 POSSIBILITY OF SUCH DAMAGES. |
|
287 |
|
288 END OF TERMS AND CONDITIONS |
|
289 |
|
290 Appendix: How to Apply These Terms to Your New Programs |
|
291 |
|
292 If you develop a new program, and you want it to be of the greatest |
|
293 possible use to the public, the best way to achieve this is to make it |
|
294 free software which everyone can redistribute and change under these terms. |
|
295 |
|
296 To do so, attach the following notices to the program. It is safest |
|
297 to attach them to the start of each source file to most effectively |
|
298 convey the exclusion of warranty; and each file should have at least |
|
299 the "copyright" line and a pointer to where the full notice is found. |
|
300 |
|
301 <one line to give the program's name and a brief idea of what it does.> |
|
302 Copyright (C) 19yy <name of author> |
|
303 |
|
304 This program is free software; you can redistribute it and/or modify |
|
305 it under the terms of the GNU General Public License as published by |
|
306 the Free Software Foundation; either version 2 of the License, or |
|
307 (at your option) any later version. |
|
308 |
|
309 This program is distributed in the hope that it will be useful, |
|
310 but WITHOUT ANY WARRANTY; without even the implied warranty of |
|
311 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
|
312 GNU General Public License for more details. |
|
313 |
|
314 You should have received a copy of the GNU General Public License |
|
315 along with this program; if not, write to the Free Software |
|
316 Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. |
|
317 |
|
318 Also add information on how to contact you by electronic and paper mail. |
|
319 |
|
320 If the program is interactive, make it output a short notice like this |
|
321 when it starts in an interactive mode: |
|
322 |
|
323 Gnomovision version 69, Copyright (C) 19yy name of author |
|
324 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
|
325 This is free software, and you are welcome to redistribute it |
|
326 under certain conditions; type `show c' for details. |
|
327 |
|
328 The hypothetical commands `show w' and `show c' should show the appropriate |
|
329 parts of the General Public License. Of course, the commands you use may |
|
330 be called something other than `show w' and `show c'; they could even be |
|
331 mouse-clicks or menu items--whatever suits your program. |
|
332 |
|
333 You should also get your employer (if you work as a programmer) or your |
|
334 school, if any, to sign a "copyright disclaimer" for the program, if |
|
335 necessary. Here is a sample; alter the names: |
|
336 |
|
337 Yoyodyne, Inc., hereby disclaims all copyright interest in the program |
|
338 `Gnomovision' (which makes passes at compilers) written by James Hacker. |

342 |
|
343 This General Public License does not permit incorporating your program into |
|
344 proprietary programs. If your program is a subroutine library, you may |
|
345 consider it more useful to permit linking proprietary applications with the |
|
346 library. If this is what you want to do, use the GNU Library General |
|
347 Public License instead of this License. |
