20 | Everyone is permitted to copy and distribute verbatim copies | |
21 | of this license document, but changing it is not allowed. | |

24 | @unnumberedsec Preamble | |
25 | ||
26 | The license agreements of most software companies try to keep users | |
27 | at the mercy of those companies. By contrast, our General Public | |
28 | License is intended to guarantee your freedom to share and change free | |
29 | software---to make sure the software is free for all its users. The | |
30 | General Public License applies to the Free Software Foundation's | |
31 | software and to any other program whose authors commit to using it. | |
32 | You can use it for your programs, too. | |
33 | ||
34 | When we speak of free software, we are referring to freedom, not | |
35 | price. Specifically, the General Public License is designed to make | |
36 | sure that you have the freedom to give away or sell copies of free | |
37 | software, that you receive source code or can get it if you want it, | |
38 | that you can change the software or use pieces of it in new free | |
39 | programs; and that you know you can do these things. | |
40 | ||
41 | To protect your rights, we need to make restrictions that forbid | |
42 | anyone to deny you these rights or to ask you to surrender the rights. | |
43 | These restrictions translate to certain responsibilities for you if you | |
44 | distribute copies of the software, or if you modify it. | |
45 | ||
46 | For example, if you distribute copies of a such a program, whether | |
47 | gratis or for a fee, you must give the recipients all the rights that | |
48 | you have. You must make sure that they, too, receive or can get the | |
49 | source code. And you must tell them their rights. | |
50 | ||
51 | We protect your rights with two steps: (1) copyright the software, and | |
52 | (2) offer you this license which gives you legal permission to copy, | |
53 | distribute and/or modify the software. | |
54 | ||
55 | Also, for each author's protection and ours, we want to make certain | |
56 | that everyone understands that there is no warranty for this free | |
57 | software. If the software is modified by someone else and passed on, we | |
58 | want its recipients to know that what they have is not the original, so | |
59 | that any problems introduced by others will not reflect on the original | |
60 | authors' reputations. | |
61 | ||
62 | The precise terms and conditions for copying, distribution and | |
63 | modification follow. | |

73 | @item | |
74 | This License Agreement applies to any program or other work which | |
75 | contains a notice placed by the copyright holder saying it may be | |
76 | distributed under the terms of this General Public License. The | |
77 | ``Program'', below, refers to any such program or work, and a ``work based | |
78 | on the Program'' means either the Program or any work containing the | |
79 | Program or a portion of it, either verbatim or with modifications. Each | |
80 | licensee is addressed as ``you''. | |
81 | ||
82 | @item | |
83 | You may copy and distribute verbatim copies of the Program's source | |
84 | code 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 | General Public License and to the absence of any warranty; and give any | |
88 | other recipients of the Program a copy of this General Public License | |
89 | along with the Program. You may charge a fee for the physical act of | |
90 | transferring a copy. | |
91 | ||
92 | @item | |
93 | You may modify your copy or copies of the Program or any portion of | |
94 | it, and copy and distribute such modifications under the terms of Paragraph | |
95 | 1 above, provided that you also do the following: | |
96 | ||
97 | @itemize @bullet | |
98 | @item | |
99 | cause the modified files to carry prominent notices stating that | |
100 | you changed the files and the date of any change; and | |
101 | ||
102 | @item | |
103 | cause the whole of any work that you distribute or publish, that | |
104 | in whole or in part contains the Program or any part thereof, either | |
105 | with or without modifications, to be licensed at no charge to all | |
106 | third parties under the terms of this General Public License (except | |
107 | that you may choose to grant warranty protection to some or all | |
108 | third parties, at your option). | |
109 | ||
110 | @item | |
111 | If the modified program normally reads commands interactively when | |
112 | run, you must cause it, when started running for such interactive use | |
113 | in the simplest and most usual way, to print or display an | |
114 | announcement including an appropriate copyright notice and a notice | |
115 | that there is no warranty (or else, saying that you provide a | |
116 | warranty) and that users may redistribute the program under these | |
117 | conditions, and telling the user how to view a copy of this General | |
118 | Public License. | |
119 | ||
120 | @item | |
121 | You may charge a fee for the physical act of transferring a | |
122 | copy, and you may at your option offer warranty protection in | |
123 | exchange for a fee. | |
124 | @end itemize | |
125 | ||
126 | Mere aggregation of another independent work with the Program (or its | |
127 | derivative) on a volume of a storage or distribution medium does not bring | |
128 | the other work under the scope of these terms. | |
129 | ||
130 | @item | |
131 | You may copy and distribute the Program (or a portion or derivative of | |
132 | it, under Paragraph 2) in object code or executable form under the terms of | |
133 | Paragraphs 1 and 2 above provided that you also do one of the following: | |
134 | ||
135 | @itemize @bullet | |
136 | @item | |
137 | accompany it with the complete corresponding machine-readable | |
138 | source code, which must be distributed under the terms of | |
139 | Paragraphs 1 and 2 above; or, | |
140 | ||
141 | @item | |
142 | accompany it with a written offer, valid for at least three | |
143 | years, to give any third party free (except for a nominal charge | |
144 | for the cost of distribution) a complete machine-readable copy of the | |
145 | corresponding source code, to be distributed under the terms of | |
146 | Paragraphs 1 and 2 above; or, | |
147 | ||
148 | @item | |
149 | accompany it with the information you received as to where the | |
150 | corresponding source code may be obtained. (This alternative is | |
151 | allowed only for noncommercial distribution and only if you | |
152 | received the program in object code or executable form alone.) | |
153 | @end itemize | |
154 | ||
155 | Source code for a work means the preferred form of the work for making | |
156 | modifications to it. For an executable file, complete source code means | |
157 | all the source code for all modules it contains; but, as a special | |
158 | exception, it need not include source code for modules which are standard | |
159 | libraries that accompany the operating system on which the executable | |
160 | file runs, or for standard header files or definitions files that | |
161 | accompany that operating system. | |
162 | ||
163 | @item | |
164 | You may not copy, modify, sublicense, distribute or transfer the | |
165 | Program except as expressly provided under this General Public License. | |
166 | Any attempt otherwise to copy, modify, sublicense, distribute or transfer | |
167 | the Program is void, and will automatically terminate your rights to use | |
168 | the Program under this License. However, parties who have received | |
169 | copies, or rights to use copies, from you under this General Public | |
170 | License will not have their licenses terminated so long as such parties | |
171 | remain in full compliance. | |
172 | ||
173 | @item | |
174 | By copying, distributing or modifying the Program (or any work based | |
175 | on the Program) you indicate your acceptance of this license to do so, | |
176 | and all its terms and conditions. | |
177 | ||
178 | @item | |
179 | Each time you redistribute the Program (or any work based on the | |
180 | Program), the recipient automatically receives a license from the original | |
181 | licensor to copy, distribute or modify the Program subject to these | |
182 | terms and conditions. You may not impose any further restrictions on the | |
183 | recipients' exercise of the rights granted herein. | |
184 | ||
185 | @item | |
186 | The Free Software Foundation may publish revised and/or new versions | |
187 | of the General Public License from time to time. Such new versions will | |
188 | be similar in spirit to the present version, but may differ in detail to | |
189 | address new problems or concerns. | |
190 | ||
191 | Each version is given a distinguishing version number. If the Program | |
192 | specifies a version number of the license which applies to it and ``any | |
193 | later version'', you have the option of following the terms and conditions | |
194 | either of that version or of any later version published by the Free | |
195 | Software Foundation. If the Program does not specify a version number of | |
196 | the license, you may choose any version ever published by the Free Software | |
197 | Foundation. | |
198 | ||
199 | @item | |
200 | If you wish to incorporate parts of the Program into other free | |
201 | programs whose distribution conditions are different, write to the author | |
202 | to ask for permission. For software which is copyrighted by the Free | |
203 | Software Foundation, write to the Free Software Foundation; we sometimes | |
204 | make exceptions for this. Our decision will be guided by the two goals | |
205 | of preserving the free status of all derivatives of our free software and | |
206 | of promoting the sharing and reuse of software generally. | |

219 | PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED | |
220 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF | |
221 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS | |

232 | LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES | |
233 | SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE | |
234 | WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN | |

246 | @unnumberedsec Applying These Terms to Your New Programs | |
247 | ||
248 | If you develop a new program, and you want it to be of the greatest | |
249 | possible use to humanity, the best way to achieve this is to make it | |
250 | free software which everyone can redistribute and change under these | |
251 | terms. | |
252 | ||
253 | To do so, attach the following notices to the program. It is safest to | |
254 | attach them to the start of each source file to most effectively convey | |
255 | the exclusion of warranty; and each file should have at least the | |
256 | ``copyright'' line and a pointer to where the full notice is found. | |
257 | ||
258 | @smallexample | |
259 | @var{one line to give the program's name and a brief idea of what it does.} | |

262 | This program is free software; you can redistribute it and/or modify | |
263 | it under the terms of the GNU General Public License as published by | |

268 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |

270 | GNU General Public License for more details. | |
271 | ||
272 | You should have received a copy of the GNU General Public License | |

274 | Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. | |
275 | @end smallexample | |
276 | ||
277 | Also add information on how to contact you by electronic and paper mail. | |
278 | ||
279 | If the program is interactive, make it output a short notice like this | |
280 | when it starts in an interactive mode: | |
281 | ||
282 | @smallexample | |
283 | Gnomovision version 69, Copyright (C) 19@var{yy} @var{name of author} | |
284 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. | |
285 | This is free software, and you are welcome to redistribute it | |
286 | under certain conditions; type `show c' for details. | |
287 | @end smallexample | |
288 | ||
289 | The hypothetical commands `show w' and `show c' should show the | |
290 | appropriate parts of the General Public License. Of course, the | |
291 | commands you use may be called something other than `show w' and `show | |
292 | c'; they could even be mouse-clicks or menu items---whatever suits your | |
293 | program. | |
294 | ||
295 | You should also get your employer (if you work as a programmer) or your | |
296 | school, if any, to sign a ``copyright disclaimer'' for the program, if | |
297 | necessary. Here is a sample; alter the names: | |
