26 <title>GNU General Public License</title>
27 <sect1>
28 <title>Preamble</title>
29 <para> The licenses for most software are designed to take away your
30 freedom to share and change it. By contrast, the GNU General Public License is
31 intended to guarantee your freedom to share and change
32 free software - to make sure the software is free for all its users.
33 This General Public License applies to most of the Free Software
34 Foundation's software and to any other program whose authors commit
35 to using it. (Some other Free Software Foundation software is covered
36 by the GNU Library General Public License instead.) You can apply it
37 to your programs, too.
38 </para>
39 <para> When we speak of free software, we are referring to freedom, not price.
40 Our General Public Licenses are designed to make sure that you have the
41 freedom to distribute copies of free software (and charge for this
42 service if you wish), that you receive source code or can get it if you
43 want it, that you can change the software or use pieces of it in new free
44 programs; and that you know you can do these things.
45 </para>
46 <para> To protect your rights, we need to make restrictions that forbid anyone
47 to deny you these rights or to ask you to surrender the rights. These
48 restrictions translate to certain responsibilities for you if you distribute
49 copies of the software, or if you modify it.
50 </para>
51 <para> For example, if you distribute copies of such a program, whether gratis or
52 for a fee, you must give the recipients all the rights that you have. You
53 must make sure that they, too, receive or can get the source code. And you
54 must show them these terms so they know their rights.
55 </para>
56 <para> We protect your rights with two steps:
57 <orderedlist>
58 <listitem>
59 <para> copyright the software, and
60 </para>
61 </listitem>
62 <listitem>
63 <para> offer you this license which gives you legal permission to copy,
64 distribute and/or modify the software.
65 </para>
66 </listitem>
67 </orderedlist>
68 </para>
69 <para> Also, for each author's protection and ours, we want to make certain that
70 everyone understands that there is no warranty for this free software. If
71 the software is modified by someone else and passed on, we want its
72 recipients to know that what they have is not the original, so that any
73 problems introduced by others will not reflect on the original authors'
74 reputations.
75 </para>
76 <para> Finally, any free program is threatened constantly by software patents.
77 We wish to avoid the danger that redistributors of a free program will
78 individually obtain patent licenses, in effect making the program
79 proprietary. To prevent this, we have made it clear that any patent must be
80 licensed for everyone's free use or not licensed at all.
81 </para>
82 <para> The precise terms and conditions for copying, distribution and modification
83 follow.
84 </para>
85 </sect1>
86 <sect1>
87 <title>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</title>
88 <sect2>
89 <title>Section 0</title>
90 <para> This License applies to any program or other work which contains a notice
91 placed by the copyright holder saying it may be distributed under the terms
92 of this General Public License. The "Program", below, refers to any such
93 program or work, and a
94 <quote>work based on the Program
95 </quote> means either
96 the Program or any derivative work under copyright law: that is to say, a
97 work containing the Program or a portion of it, either verbatim or with
98 modifications and/or translated into another language. (Hereinafter, translation
99 is included without limitation in the term
100 <quote>modification
101 </quote>.) Each licensee is addressed as <quote>you</quote>.
102 </para>
103 <para> Activities other than copying, distribution and modification are not covered by
104 this License; they are outside its scope. The act of running the Program is not
105 restricted, and the output from the Program is covered only if its contents
106 constitute a work based on the Program (independent of having been made by running
107 the Program). Whether that is true depends on what the Program does.
108 </para>
109 </sect2>
110 <sect2 id="sect1">
111 <title>Section 1</title>
112 <para> You may copy and distribute verbatim copies of the Program's source code as you
113 receive it, in any medium, provided that you conspicuously and appropriately
114 publish on each copy an appropriate copyright notice and disclaimer of warranty;
115 keep intact all the notices that refer to this License and to the absence of any
116 warranty; and give any other recipients of the Program a copy of this License
117 along with the Program.
118 </para>
119 <para> You may charge a fee for the physical act of transferring a copy, and you may at
120 your option offer warranty protection in exchange for a fee.
121 </para>
122 </sect2>
123 <sect2 id="sect2">
124 <title>Section 2</title>
125 <para> You may modify your copy or copies of the Program or any portion of it, thus
126 forming a work based on the Program, and copy and distribute such modifications
127 or work under the terms of
128 <link linkend="sect1">Section 1
129 </link> above, provided
130 that you also meet all of these conditions:
131 <orderedlist>
132 <listitem>
133 <para> You must cause the modified files to carry prominent notices stating that
134 you changed the files and the date of any change.
135 </para>
136 </listitem>
137 <listitem>
138 <para> You must cause any work that you distribute or publish, that in whole or
139 in part contains or is derived from the Program or any part thereof, to be
140 licensed as a whole at no charge to all third parties under the terms of
141 this License.
142 </para>
143 </listitem>
144 <listitem>
145 <para> If the modified program normally reads commands interactively when run, you
146 must cause it, when started running for such interactive use in the most
147 ordinary way, to print or display an announcement including an appropriate
148 copyright notice and a notice that there is no warranty (or else, saying
149 that you provide a warranty) and that users may redistribute the program
150 under these conditions, and telling the user how to view a copy of this
151 License.
152 <note>
153 <title>Exception:
154 </title>
155 <para> If the Program itself is interactive but does not normally print such an
156 announcement, your work based on the Program is not required to print an
157 announcement.)
158 </para>
159 </note>
160 </para>
161 </listitem>
162 </orderedlist>
163 </para>
164 <para> These requirements apply to the modified work as a whole. If identifiable sections
165 of that work are not derived from the Program, and can be reasonably considered
166 independent and separate works in themselves, then this License, and its terms,
167 do not apply to those sections when you distribute them as separate works. But when
168 you distribute the same sections as part of a whole which is a work based on the
169 Program, the distribution of the whole must be on the terms of this License, whose
170 permissions for other licensees extend to the entire whole, and thus to each and
171 every part regardless of who wrote it.
172 </para>
173 <para> Thus, it is not the intent of this section to claim rights or contest your rights
174 to work written entirely by you; rather, the intent is to exercise the right to control
175 the distribution of derivative or collective works based on the Program.
176 </para>
177 <para> In addition, mere aggregation of another work not based on the Program with the Program
178 (or with a work based on the Program) on a volume of a storage or distribution medium
179 does not bring the other work under the scope of this License.
180 </para>
181 </sect2>
182 <sect2>
183 <title>Section 3
184 </title>
185 <para> You may copy and distribute the Program (or a work based on it, under
186 <link linkend="sect2">Section 2
187 </link> in object code or executable form under the terms of
188 <link linkend="sect1">Sections 1
189 </link> and
190 <link linkend="sect2">2
191 </link> above provided that you also do one of the following:
192 <orderedlist>
193 <listitem>
194 <para> Accompany it with the complete corresponding machine-readable source code, which
195 must be distributed under the terms of Sections 1 and 2 above on a medium
196 customarily used for software interchange; or,
197 </para>
198 </listitem>
199 <listitem>
200 <para> Accompany it with a written offer, valid for at least three years, to give any
201 third party, for a charge no more than your cost of physically performing source
202 distribution, a complete machine-readable copy of the corresponding source code,
203 to be distributed under the terms of Sections 1 and 2 above on a medium customarily
204 used for software interchange; or,
205 </para>
206 </listitem>
207 <listitem>
208 <para> Accompany it with the information you received as to the offer to distribute
209 corresponding source code. (This alternative is allowed only for noncommercial
210 distribution and only if you received the program in object code or executable form
211 with such an offer, in accord with Subsection b above.)
212 </para>
213 </listitem>
214 </orderedlist>
215 </para>
216 <para> The source code for a work means the preferred form of the work for making modifications
217 to it. For an executable work, complete source code means all the source code for all modules
218 it contains, plus any associated interface definition files, plus the scripts used to control
219 compilation and installation of the executable. However, as a special exception, the source
220 code distributed need not include anything that is normally distributed (in either source or
221 binary form) with the major components (compiler, kernel, and so on) of the operating system
222 on which the executable runs, unless that component itself accompanies the executable.
223 </para>
224 <para> If distribution of executable or object code is made by offering access to copy from a
225 designated place, then offering equivalent access to copy the source code from the same place
226 counts as distribution of the source code, even though third parties are not compelled to
227 copy the source along with the object code.
228 </para>
229 </sect2>
230 <sect2>
231 <title>Section 4
232 </title>
233 <para> You may not copy, modify, sublicense, or distribute the Program except as expressly provided
234 under this License. Any attempt otherwise to copy, modify, sublicense or distribute the
235 Program is void, and will automatically terminate your rights under this License. However,
236 parties who have received copies, or rights, from you under this License will not have their
237 licenses terminated so long as such parties remain in full compliance.
238 </para>
239 </sect2>
240 <sect2>
241 <title>Section 5
242 </title>
243 <para> You are not required to accept this License, since you have not signed it. However, nothing
244 else grants you permission to modify or distribute the Program or its derivative works.
245 These actions are prohibited by law if you do not accept this License. Therefore, by modifying
246 or distributing the Program (or any work based on the Program), you indicate your acceptance
247 of this License to do so, and all its terms and conditions for copying, distributing or
248 modifying the Program or works based on it.
249 </para>
250 </sect2>
251 <sect2>
252 <title>Section 6
253 </title>
254 <para> Each time you redistribute the Program (or any work based on the Program), the recipient
255 automatically receives a license from the original licensor to copy, distribute or modify
256 the Program subject to these terms and conditions. You may not impose any further restrictions
257 on the recipients' exercise of the rights granted herein. You are not responsible for enforcing
258 compliance by third parties to this License.
259 </para>
260 </sect2>
261 <sect2>
262 <title>Section 7
263 </title>
264 <para> If, as a consequence of a court judgment or allegation of patent infringement or for any other
265 reason (not limited to patent issues), conditions are imposed on you (whether by court order,
266 agreement or otherwise) that contradict the conditions of this License, they do not excuse you
267 from the conditions of this License. If you cannot distribute so as to satisfy simultaneously
268 your obligations under this License and any other pertinent obligations, then as a consequence
269 you may not distribute the Program at all. For example, if a patent license would not permit
270 royalty-free redistribution of the Program by all those who receive copies directly or
271 indirectly through you, then the only way you could satisfy both it and this License would be
272 to refrain entirely from distribution of the Program.
273 </para>
274 <para> If any portion of this section is held invalid or unenforceable under any particular circumstance,
275 the balance of the section is intended to apply and the section as a whole is intended to apply
276 in other circumstances.
277 </para>
278 <para> It is not the purpose of this section to induce you to infringe any patents or other property
279 right claims or to contest validity of any such claims; this section has the sole purpose of
280 protecting the integrity of the free software distribution system, which is implemented by public
281 license practices. Many people have made generous contributions to the wide range of software
282 distributed through that system in reliance on consistent application of that system; it is up
283 to the author/donor to decide if he or she is willing to distribute software through any other
284 system and a licensee cannot impose that choice.
285 </para>
286 <para> This section is intended to make thoroughly clear what is believed to be a consequence of the
287 rest of this License.
288 </para>
289 </sect2>
290 <sect2>
291 <title>Section 8
292 </title>
293 <para> If the distribution and/or use of the Program is restricted in certain countries either by patents
294 or by copyrighted interfaces, the original copyright holder who places the Program under this License
295 may add an explicit geographical distribution limitation excluding those countries, so that
296 distribution is permitted only in or among countries not thus excluded. In such case, this License
297 incorporates the limitation as if written in the body of this License.

305 in detail to address new problems or concerns.
306 </para>
307 <para> Each version is given a distinguishing version number. If the Program specifies a version number of
308 this License which applies to it and "any later version", you have the option of following the terms
309 and conditions either of that version or of any later version published by the Free Software
310 Foundation. If the Program does not specify a version number of this License, you may choose any
311 version ever published by the Free Software Foundation.

318 conditions are different, write to the author to ask for permission. For software which is copyrighted
319 by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions
320 for this. Our decision will be guided by the two goals of preserving the free status of all
321 derivatives of our free software and of promoting the sharing and reuse of software generally.

330 INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
331 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE

341 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED

351 <title>How to Apply These Terms to Your New Programs
352 </title>
353 <para>
354 If you develop a new program, and you want it to be of the greatest
355 possible use to the public, the best way to achieve this is to make it
356 free software which everyone can redistribute and change under these terms.
357 </para>
358 <para>
359 To do so, attach the following notices to the program. It is safest
360 to attach them to the start of each source file to most effectively
361 convey the exclusion of warranty; and each file should have at least
362 the "copyright" line and a pointer to where the full notice is found.

370 it under the terms of the GNU General Public License as published by

394 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
395 This is free software, and you are welcome to redistribute it
396 under certain conditions; type `show c' for details.
397 </para>
398 <para>
399 The hypothetical commands `show w' and `show c' should show the appropriate
400 parts of the General Public License. Of course, the commands you use may
401 be called something other than `show w' and `show c'; they could even be
402 mouse-clicks or menu items--whatever suits your program.

404 <para>
405 You should also get your employer (if you work as a programmer) or your

422 Public License instead of this License.
