6 | 3ef693a0 | bellard | Everyone is permitted to copy and distribute verbatim copies |
7 | 3ef693a0 | bellard | of this license document, but changing it is not allowed. |
8 | 3ef693a0 | bellard | |
9 | 3ef693a0 | bellard | Preamble |
10 | 3ef693a0 | bellard | |
11 | 3ef693a0 | bellard | The licenses for most software are designed to take away your |
12 | 3ef693a0 | bellard | freedom to share and change it. By contrast, the GNU General Public |
13 | 3ef693a0 | bellard | License is intended to guarantee your freedom to share and change free |
14 | 3ef693a0 | bellard | software--to make sure the software is free for all its users. This |
15 | 3ef693a0 | bellard | General Public License applies to most of the Free Software |
16 | 3ef693a0 | bellard | Foundation's software and to any other program whose authors commit to |
17 | 3ef693a0 | bellard | using it. (Some other Free Software Foundation software is covered by |
18 | 3ef693a0 | bellard | the GNU Library General Public License instead.) You can apply it to |
19 | 3ef693a0 | bellard | your programs, too. |
20 | 3ef693a0 | bellard | |
21 | 3ef693a0 | bellard | When we speak of free software, we are referring to freedom, not |
22 | 3ef693a0 | bellard | price. Our General Public Licenses are designed to make sure that you |
23 | 3ef693a0 | bellard | have the freedom to distribute copies of free software (and charge for |
24 | 3ef693a0 | bellard | this service if you wish), that you receive source code or can get it |
25 | 3ef693a0 | bellard | if you want it, that you can change the software or use pieces of it |
26 | 3ef693a0 | bellard | in new free programs; and that you know you can do these things. |
27 | 3ef693a0 | bellard | |
28 | 3ef693a0 | bellard | To protect your rights, we need to make restrictions that forbid |
29 | 3ef693a0 | bellard | anyone to deny you these rights or to ask you to surrender the rights. |
30 | 3ef693a0 | bellard | These restrictions translate to certain responsibilities for you if you |
31 | 3ef693a0 | bellard | distribute copies of the software, or if you modify it. |
32 | 3ef693a0 | bellard | |
33 | 3ef693a0 | bellard | For example, if you distribute copies of such a program, whether |
34 | 3ef693a0 | bellard | gratis or for a fee, you must give the recipients all the rights that |
35 | 3ef693a0 | bellard | you have. You must make sure that they, too, receive or can get the |
36 | 3ef693a0 | bellard | source code. And you must show them these terms so they know their |
37 | 3ef693a0 | bellard | rights. |
38 | 3ef693a0 | bellard | |
39 | 3ef693a0 | bellard | We protect your rights with two steps: (1) copyright the software, and |
40 | 3ef693a0 | bellard | (2) offer you this license which gives you legal permission to copy, |
41 | 3ef693a0 | bellard | distribute and/or modify the software. |
42 | 3ef693a0 | bellard | |
43 | 3ef693a0 | bellard | Also, for each author's protection and ours, we want to make certain |
44 | 3ef693a0 | bellard | that everyone understands that there is no warranty for this free |
45 | 3ef693a0 | bellard | software. If the software is modified by someone else and passed on, we |
46 | 3ef693a0 | bellard | want its recipients to know that what they have is not the original, so |
47 | 3ef693a0 | bellard | that any problems introduced by others will not reflect on the original |
48 | 3ef693a0 | bellard | authors' reputations. |
49 | 3ef693a0 | bellard | |
50 | 3ef693a0 | bellard | Finally, any free program is threatened constantly by software |
51 | 3ef693a0 | bellard | patents. We wish to avoid the danger that redistributors of a free |
52 | 3ef693a0 | bellard | program will individually obtain patent licenses, in effect making the |
53 | 3ef693a0 | bellard | program proprietary. To prevent this, we have made it clear that any |
54 | 3ef693a0 | bellard | patent must be licensed for everyone's free use or not licensed at all. |
55 | 3ef693a0 | bellard | |
56 | 3ef693a0 | bellard | The precise terms and conditions for copying, distribution and |
57 | 3ef693a0 | bellard | modification follow. |
58 | 3ef693a0 | bellard | |
59 | 3ef693a0 | bellard | GNU GENERAL PUBLIC LICENSE |
60 | 3ef693a0 | bellard | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
61 | 3ef693a0 | bellard | |
62 | 3ef693a0 | bellard | 0. This License applies to any program or other work which contains |
63 | 3ef693a0 | bellard | a notice placed by the copyright holder saying it may be distributed |
64 | 3ef693a0 | bellard | under the terms of this General Public License. The "Program", below, |
65 | 3ef693a0 | bellard | refers to any such program or work, and a "work based on the Program" |
66 | 3ef693a0 | bellard | means either the Program or any derivative work under copyright law: |
67 | 3ef693a0 | bellard | that is to say, a work containing the Program or a portion of it, |
68 | 3ef693a0 | bellard | either verbatim or with modifications and/or translated into another |
69 | 3ef693a0 | bellard | language. (Hereinafter, translation is included without limitation in |
70 | 3ef693a0 | bellard | the term "modification".) Each licensee is addressed as "you". |
71 | 3ef693a0 | bellard | |
72 | 3ef693a0 | bellard | Activities other than copying, distribution and modification are not |
73 | 3ef693a0 | bellard | covered by this License; they are outside its scope. The act of |
74 | 3ef693a0 | bellard | running the Program is not restricted, and the output from the Program |
75 | 3ef693a0 | bellard | is covered only if its contents constitute a work based on the |
76 | 3ef693a0 | bellard | Program (independent of having been made by running the Program). |
77 | 3ef693a0 | bellard | Whether that is true depends on what the Program does. |
78 | 3ef693a0 | bellard | |
79 | 3ef693a0 | bellard | 1. You may copy and distribute verbatim copies of the Program's |
80 | 3ef693a0 | bellard | source code as you receive it, in any medium, provided that you |
81 | 3ef693a0 | bellard | conspicuously and appropriately publish on each copy an appropriate |
82 | 3ef693a0 | bellard | copyright notice and disclaimer of warranty; keep intact all the |
83 | 3ef693a0 | bellard | notices that refer to this License and to the absence of any warranty; |
84 | 3ef693a0 | bellard | and give any other recipients of the Program a copy of this License |
85 | 3ef693a0 | bellard | along with the Program. |
86 | 3ef693a0 | bellard | |
87 | 3ef693a0 | bellard | You may charge a fee for the physical act of transferring a copy, and |
88 | 3ef693a0 | bellard | you may at your option offer warranty protection in exchange for a fee. |
89 | 3ef693a0 | bellard | |
90 | 3ef693a0 | bellard | 2. You may modify your copy or copies of the Program or any portion |
91 | 3ef693a0 | bellard | of it, thus forming a work based on the Program, and copy and |
92 | 3ef693a0 | bellard | distribute such modifications or work under the terms of Section 1 |
93 | 3ef693a0 | bellard | above, provided that you also meet all of these conditions: |
94 | 3ef693a0 | bellard | |
95 | 3ef693a0 | bellard | a) You must cause the modified files to carry prominent notices |
96 | 3ef693a0 | bellard | stating that you changed the files and the date of any change. |
97 | 3ef693a0 | bellard | |
98 | 3ef693a0 | bellard | b) You must cause any work that you distribute or publish, that in |
99 | 3ef693a0 | bellard | whole or in part contains or is derived from the Program or any |
100 | 3ef693a0 | bellard | part thereof, to be licensed as a whole at no charge to all third |
101 | 3ef693a0 | bellard | parties under the terms of this License. |
102 | 3ef693a0 | bellard | |
103 | 3ef693a0 | bellard | c) If the modified program normally reads commands interactively |
104 | 3ef693a0 | bellard | when run, you must cause it, when started running for such |
105 | 3ef693a0 | bellard | interactive use in the most ordinary way, to print or display an |
106 | 3ef693a0 | bellard | announcement including an appropriate copyright notice and a |
107 | 3ef693a0 | bellard | notice that there is no warranty (or else, saying that you provide |
108 | 3ef693a0 | bellard | a warranty) and that users may redistribute the program under |
109 | 3ef693a0 | bellard | these conditions, and telling the user how to view a copy of this |
110 | 3ef693a0 | bellard | License. (Exception: if the Program itself is interactive but |
111 | 3ef693a0 | bellard | does not normally print such an announcement, your work based on |
112 | 3ef693a0 | bellard | the Program is not required to print an announcement.) |
113 | 3ef693a0 | bellard | |
114 | 3ef693a0 | bellard | These requirements apply to the modified work as a whole. If |
115 | 3ef693a0 | bellard | identifiable sections of that work are not derived from the Program, |
116 | 3ef693a0 | bellard | and can be reasonably considered independent and separate works in |
117 | 3ef693a0 | bellard | themselves, then this License, and its terms, do not apply to those |
118 | 3ef693a0 | bellard | sections when you distribute them as separate works. But when you |
119 | 3ef693a0 | bellard | distribute the same sections as part of a whole which is a work based |
120 | 3ef693a0 | bellard | on the Program, the distribution of the whole must be on the terms of |
121 | 3ef693a0 | bellard | this License, whose permissions for other licensees extend to the |
122 | 3ef693a0 | bellard | entire whole, and thus to each and every part regardless of who wrote it. |
123 | 3ef693a0 | bellard | |
124 | 3ef693a0 | bellard | Thus, it is not the intent of this section to claim rights or contest |
125 | 3ef693a0 | bellard | your rights to work written entirely by you; rather, the intent is to |
126 | 3ef693a0 | bellard | exercise the right to control the distribution of derivative or |
127 | 3ef693a0 | bellard | collective works based on the Program. |
128 | 3ef693a0 | bellard | |
129 | 3ef693a0 | bellard | In addition, mere aggregation of another work not based on the Program |
130 | 3ef693a0 | bellard | with the Program (or with a work based on the Program) on a volume of |
131 | 3ef693a0 | bellard | a storage or distribution medium does not bring the other work under |
132 | 3ef693a0 | bellard | the scope of this License. |
133 | 3ef693a0 | bellard | |
134 | 3ef693a0 | bellard | 3. You may copy and distribute the Program (or a work based on it, |
135 | 3ef693a0 | bellard | under Section 2) in object code or executable form under the terms of |
136 | 3ef693a0 | bellard | Sections 1 and 2 above provided that you also do one of the following: |
137 | 3ef693a0 | bellard | |
138 | 3ef693a0 | bellard | a) Accompany it with the complete corresponding machine-readable |
139 | 3ef693a0 | bellard | source code, which must be distributed under the terms of Sections |
140 | 3ef693a0 | bellard | 1 and 2 above on a medium customarily used for software interchange; or, |
141 | 3ef693a0 | bellard | |
142 | 3ef693a0 | bellard | b) Accompany it with a written offer, valid for at least three |
143 | 3ef693a0 | bellard | years, to give any third party, for a charge no more than your |
144 | 3ef693a0 | bellard | cost of physically performing source distribution, a complete |
145 | 3ef693a0 | bellard | machine-readable copy of the corresponding source code, to be |
146 | 3ef693a0 | bellard | distributed under the terms of Sections 1 and 2 above on a medium |
147 | 3ef693a0 | bellard | customarily used for software interchange; or, |
148 | 3ef693a0 | bellard | |
149 | 3ef693a0 | bellard | c) Accompany it with the information you received as to the offer |
150 | 3ef693a0 | bellard | to distribute corresponding source code. (This alternative is |
151 | 3ef693a0 | bellard | allowed only for noncommercial distribution and only if you |
152 | 3ef693a0 | bellard | received the program in object code or executable form with such |
153 | 3ef693a0 | bellard | an offer, in accord with Subsection b above.) |
154 | 3ef693a0 | bellard | |
155 | 3ef693a0 | bellard | The source code for a work means the preferred form of the work for |
156 | 3ef693a0 | bellard | making modifications to it. For an executable work, complete source |
157 | 3ef693a0 | bellard | code means all the source code for all modules it contains, plus any |
158 | 3ef693a0 | bellard | associated interface definition files, plus the scripts used to |
159 | 3ef693a0 | bellard | control compilation and installation of the executable. However, as a |
160 | 3ef693a0 | bellard | special exception, the source code distributed need not include |
161 | 3ef693a0 | bellard | anything that is normally distributed (in either source or binary |
162 | 3ef693a0 | bellard | form) with the major components (compiler, kernel, and so on) of the |
163 | 3ef693a0 | bellard | operating system on which the executable runs, unless that component |
164 | 3ef693a0 | bellard | itself accompanies the executable. |
165 | 3ef693a0 | bellard | |
166 | 3ef693a0 | bellard | If distribution of executable or object code is made by offering |
167 | 3ef693a0 | bellard | access to copy from a designated place, then offering equivalent |
168 | 3ef693a0 | bellard | access to copy the source code from the same place counts as |
169 | 3ef693a0 | bellard | distribution of the source code, even though third parties are not |
170 | 3ef693a0 | bellard | compelled to copy the source along with the object code. |
171 | 3ef693a0 | bellard | |
172 | 3ef693a0 | bellard | 4. You may not copy, modify, sublicense, or distribute the Program |
173 | 3ef693a0 | bellard | except as expressly provided under this License. Any attempt |
174 | 3ef693a0 | bellard | otherwise to copy, modify, sublicense or distribute the Program is |
175 | 3ef693a0 | bellard | void, and will automatically terminate your rights under this License. |
176 | 3ef693a0 | bellard | However, parties who have received copies, or rights, from you under |
177 | 3ef693a0 | bellard | this License will not have their licenses terminated so long as such |
178 | 3ef693a0 | bellard | parties remain in full compliance. |
179 | 3ef693a0 | bellard | |
180 | 3ef693a0 | bellard | 5. You are not required to accept this License, since you have not |
181 | 3ef693a0 | bellard | signed it. However, nothing else grants you permission to modify or |
182 | 3ef693a0 | bellard | distribute the Program or its derivative works. These actions are |
183 | 3ef693a0 | bellard | prohibited by law if you do not accept this License. Therefore, by |
184 | 3ef693a0 | bellard | modifying or distributing the Program (or any work based on the |
185 | 3ef693a0 | bellard | Program), you indicate your acceptance of this License to do so, and |
186 | 3ef693a0 | bellard | all its terms and conditions for copying, distributing or modifying |
187 | 3ef693a0 | bellard | the Program or works based on it. |
188 | 3ef693a0 | bellard | |
189 | 3ef693a0 | bellard | 6. Each time you redistribute the Program (or any work based on the |
190 | 3ef693a0 | bellard | Program), the recipient automatically receives a license from the |
191 | 3ef693a0 | bellard | original licensor to copy, distribute or modify the Program subject to |
192 | 3ef693a0 | bellard | these terms and conditions. You may not impose any further |
193 | 3ef693a0 | bellard | restrictions on the recipients' exercise of the rights granted herein. |
194 | 3ef693a0 | bellard | You are not responsible for enforcing compliance by third parties to |
195 | 3ef693a0 | bellard | this License. |
196 | 3ef693a0 | bellard | |
197 | 3ef693a0 | bellard | 7. If, as a consequence of a court judgment or allegation of patent |
198 | 3ef693a0 | bellard | infringement or for any other reason (not limited to patent issues), |
199 | 3ef693a0 | bellard | conditions are imposed on you (whether by court order, agreement or |
200 | 3ef693a0 | bellard | otherwise) that contradict the conditions of this License, they do not |
201 | 3ef693a0 | bellard | excuse you from the conditions of this License. If you cannot |
202 | 3ef693a0 | bellard | distribute so as to satisfy simultaneously your obligations under this |
203 | 3ef693a0 | bellard | License and any other pertinent obligations, then as a consequence you |
204 | 3ef693a0 | bellard | may not distribute the Program at all. For example, if a patent |
205 | 3ef693a0 | bellard | license would not permit royalty-free redistribution of the Program by |
206 | 3ef693a0 | bellard | all those who receive copies directly or indirectly through you, then |
207 | 3ef693a0 | bellard | the only way you could satisfy both it and this License would be to |
208 | 3ef693a0 | bellard | refrain entirely from distribution of the Program. |
209 | 3ef693a0 | bellard | |
210 | 3ef693a0 | bellard | If any portion of this section is held invalid or unenforceable under |
211 | 3ef693a0 | bellard | any particular circumstance, the balance of the section is intended to |
212 | 3ef693a0 | bellard | apply and the section as a whole is intended to apply in other |
213 | 3ef693a0 | bellard | circumstances. |
214 | 3ef693a0 | bellard | |
215 | 3ef693a0 | bellard | It is not the purpose of this section to induce you to infringe any |
216 | 3ef693a0 | bellard | patents or other property right claims or to contest validity of any |
217 | 3ef693a0 | bellard | such claims; this section has the sole purpose of protecting the |
218 | 3ef693a0 | bellard | integrity of the free software distribution system, which is |
219 | 3ef693a0 | bellard | implemented by public license practices. Many people have made |
220 | 3ef693a0 | bellard | generous contributions to the wide range of software distributed |
221 | 3ef693a0 | bellard | through that system in reliance on consistent application of that |
222 | 3ef693a0 | bellard | system; it is up to the author/donor to decide if he or she is willing |
223 | 3ef693a0 | bellard | to distribute software through any other system and a licensee cannot |
224 | 3ef693a0 | bellard | impose that choice. |
225 | 3ef693a0 | bellard | |
226 | 3ef693a0 | bellard | This section is intended to make thoroughly clear what is believed to |
227 | 3ef693a0 | bellard | be a consequence of the rest of this License. |
228 | 3ef693a0 | bellard | |
229 | 3ef693a0 | bellard | 8. If the distribution and/or use of the Program is restricted in |
230 | 3ef693a0 | bellard | certain countries either by patents or by copyrighted interfaces, the |
231 | 3ef693a0 | bellard | original copyright holder who places the Program under this License |
232 | 3ef693a0 | bellard | may add an explicit geographical distribution limitation excluding |
233 | 3ef693a0 | bellard | those countries, so that distribution is permitted only in or among |
234 | 3ef693a0 | bellard | countries not thus excluded. In such case, this License incorporates |
235 | 3ef693a0 | bellard | the limitation as if written in the body of this License. |
236 | 3ef693a0 | bellard | |
237 | 3ef693a0 | bellard | 9. The Free Software Foundation may publish revised and/or new versions |
238 | 3ef693a0 | bellard | of the General Public License from time to time. Such new versions will |
239 | 3ef693a0 | bellard | be similar in spirit to the present version, but may differ in detail to |
240 | 3ef693a0 | bellard | address new problems or concerns. |
241 | 3ef693a0 | bellard | |
242 | 3ef693a0 | bellard | Each version is given a distinguishing version number. If the Program |
243 | 3ef693a0 | bellard | specifies a version number of this License which applies to it and "any |
244 | 3ef693a0 | bellard | later version", you have the option of following the terms and conditions |
245 | 3ef693a0 | bellard | either of that version or of any later version published by the Free |
246 | 3ef693a0 | bellard | Software Foundation. If the Program does not specify a version number of |
247 | 3ef693a0 | bellard | this License, you may choose any version ever published by the Free Software |
248 | 3ef693a0 | bellard | Foundation. |
249 | 3ef693a0 | bellard | |
250 | 3ef693a0 | bellard | 10. If you wish to incorporate parts of the Program into other free |
251 | 3ef693a0 | bellard | programs whose distribution conditions are different, write to the author |
252 | 3ef693a0 | bellard | to ask for permission. For software which is copyrighted by the Free |
253 | 3ef693a0 | bellard | Software Foundation, write to the Free Software Foundation; we sometimes |
254 | 3ef693a0 | bellard | make exceptions for this. Our decision will be guided by the two goals |
255 | 3ef693a0 | bellard | of preserving the free status of all derivatives of our free software and |
256 | 3ef693a0 | bellard | of promoting the sharing and reuse of software generally. |
257 | 3ef693a0 | bellard | |
258 | 3ef693a0 | bellard | NO WARRANTY |
259 | 3ef693a0 | bellard | |
260 | 3ef693a0 | bellard | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
261 | 3ef693a0 | bellard | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |
262 | 3ef693a0 | bellard | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
263 | 3ef693a0 | bellard | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |
264 | 3ef693a0 | bellard | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
265 | 3ef693a0 | bellard | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
266 | 3ef693a0 | bellard | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
267 | 3ef693a0 | bellard | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
268 | 3ef693a0 | bellard | REPAIR OR CORRECTION. |
269 | 3ef693a0 | bellard | |
270 | 3ef693a0 | bellard | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |

282 | 3ef693a0 | bellard | How to Apply These Terms to Your New Programs |
283 | 3ef693a0 | bellard | |
284 | 3ef693a0 | bellard | If you develop a new program, and you want it to be of the greatest |
285 | 3ef693a0 | bellard | possible use to the public, the best way to achieve this is to make it |
286 | 3ef693a0 | bellard | free software which everyone can redistribute and change under these terms. |
287 | 3ef693a0 | bellard | |
288 | 3ef693a0 | bellard | To do so, attach the following notices to the program. It is safest |
289 | 3ef693a0 | bellard | to attach them to the start of each source file to most effectively |
290 | 3ef693a0 | bellard | convey the exclusion of warranty; and each file should have at least |
291 | 3ef693a0 | bellard | the "copyright" line and a pointer to where the full notice is found. |
292 | 3ef693a0 | bellard | |
293 | 3ef693a0 | bellard | <one line to give the program's name and a brief idea of what it does.> |

306 | 3ef693a0 | bellard | You should have received a copy of the GNU General Public License |
307 | 3ef693a0 | bellard | along with this program; if not, write to the Free Software |

309 | 3ef693a0 | bellard | |
310 | 3ef693a0 | bellard | Also add information on how to contact you by electronic and paper mail. |
311 | 3ef693a0 | bellard | |
312 | 3ef693a0 | bellard | If the program is interactive, make it output a short notice like this |
313 | 3ef693a0 | bellard | when it starts in an interactive mode: |
314 | 3ef693a0 | bellard | |
315 | 3ef693a0 | bellard | Gnomovision version 69, Copyright (C) 19yy name of author |
316 | 3ef693a0 | bellard | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
317 | 3ef693a0 | bellard | This is free software, and you are welcome to redistribute it |
318 | 3ef693a0 | bellard | under certain conditions; type `show c' for details. |
319 | 3ef693a0 | bellard | |
320 | 3ef693a0 | bellard | The hypothetical commands `show w' and `show c' should show the appropriate |
321 | 3ef693a0 | bellard | parts of the General Public License. Of course, the commands you use may |
322 | 3ef693a0 | bellard | be called something other than `show w' and `show c'; they could even be |
323 | 3ef693a0 | bellard | mouse-clicks or menu items--whatever suits your program. |
324 | 3ef693a0 | bellard | |
325 | 3ef693a0 | bellard | You should also get your employer (if you work as a programmer) or your |
326 | 3ef693a0 | bellard | school, if any, to sign a "copyright disclaimer" for the program, if |
327 | 3ef693a0 | bellard | necessary. Here is a sample; alter the names: |
