7 1.1 christos Everyone is permitted to copy and distribute verbatim copies
8 1.1 christos of this license document, but changing it is not allowed.
9 1.1 christos
10 1.1 christos Preamble
11 1.1 christos
12 1.1 christos The licenses for most software are designed to take away your
13 1.1 christos freedom to share and change it. By contrast, the GNU General Public
14 1.1 christos License is intended to guarantee your freedom to share and change free
15 1.1 christos software--to make sure the software is free for all its users. This
16 1.1 christos General Public License applies to most of the Free Software
17 1.1 christos Foundation's software and to any other program whose authors commit to
18 1.1 christos using it. (Some other Free Software Foundation software is covered by
19 1.1 christos the GNU Library General Public License instead.) You can apply it to
20 1.1 christos your programs, too.
21 1.1 christos
22 1.1 christos When we speak of free software, we are referring to freedom, not
23 1.1 christos price. Our General Public Licenses are designed to make sure that you
24 1.1 christos have the freedom to distribute copies of free software (and charge for
25 1.1 christos this service if you wish), that you receive source code or can get it
26 1.1 christos if you want it, that you can change the software or use pieces of it
27 1.1 christos in new free programs; and that you know you can do these things.
28 1.1 christos
29 1.1 christos To protect your rights, we need to make restrictions that forbid
30 1.1 christos anyone to deny you these rights or to ask you to surrender the rights.
31 1.1 christos These restrictions translate to certain responsibilities for you if you
32 1.1 christos distribute copies of the software, or if you modify it.
33 1.1 christos
34 1.1 christos For example, if you distribute copies of such a program, whether
35 1.1 christos gratis or for a fee, you must give the recipients all the rights that
36 1.1 christos you have. You must make sure that they, too, receive or can get the
37 1.1 christos source code. And you must show them these terms so they know their
38 1.1 christos rights.
39 1.1 christos
40 1.1 christos We protect your rights with two steps: (1) copyright the software, and
41 1.1 christos (2) offer you this license which gives you legal permission to copy,
42 1.1 christos distribute and/or modify the software.
43 1.1 christos
44 1.1 christos Also, for each author's protection and ours, we want to make certain
45 1.1 christos that everyone understands that there is no warranty for this free
46 1.1 christos software. If the software is modified by someone else and passed on, we
47 1.1 christos want its recipients to know that what they have is not the original, so
48 1.1 christos that any problems introduced by others will not reflect on the original
49 1.1 christos authors' reputations.
50 1.1 christos
51 1.1 christos Finally, any free program is threatened constantly by software
52 1.1 christos patents. We wish to avoid the danger that redistributors of a free
53 1.1 christos program will individually obtain patent licenses, in effect making the
54 1.1 christos program proprietary. To prevent this, we have made it clear that any
55 1.1 christos patent must be licensed for everyone's free use or not licensed at all.
56 1.1 christos
57 1.1 christos The precise terms and conditions for copying, distribution and
58 1.1 christos modification follow.
59 1.1 christos
61 1.1 christos GNU GENERAL PUBLIC LICENSE
62 1.1 christos TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
63 1.1 christos
64 1.1 christos 0. This License applies to any program or other work which contains
65 1.1 christos a notice placed by the copyright holder saying it may be distributed
66 1.1 christos under the terms of this General Public License. The "Program", below,
67 1.1 christos refers to any such program or work, and a "work based on the Program"
68 1.1 christos means either the Program or any derivative work under copyright law:
69 1.1 christos that is to say, a work containing the Program or a portion of it,
70 1.1 christos either verbatim or with modifications and/or translated into another
71 1.1 christos language. (Hereinafter, translation is included without limitation in
72 1.1 christos the term "modification".) Each licensee is addressed as "you".
73 1.1 christos
74 1.1 christos Activities other than copying, distribution and modification are not
75 1.1 christos covered by this License; they are outside its scope. The act of
76 1.1 christos running the Program is not restricted, and the output from the Program
77 1.1 christos is covered only if its contents constitute a work based on the
78 1.1 christos Program (independent of having been made by running the Program).
79 1.1 christos Whether that is true depends on what the Program does.
80 1.1 christos
81 1.1 christos 1. You may copy and distribute verbatim copies of the Program's
82 1.1 christos source code as you receive it, in any medium, provided that you
83 1.1 christos conspicuously and appropriately publish on each copy an appropriate
84 1.1 christos copyright notice and disclaimer of warranty; keep intact all the
85 1.1 christos notices that refer to this License and to the absence of any warranty;
86 1.1 christos and give any other recipients of the Program a copy of this License
87 1.1 christos along with the Program.
88 1.1 christos
89 1.1 christos You may charge a fee for the physical act of transferring a copy, and
90 1.1 christos you may at your option offer warranty protection in exchange for a fee.
91 1.1 christos
92 1.1 christos 2. You may modify your copy or copies of the Program or any portion
93 1.1 christos of it, thus forming a work based on the Program, and copy and
94 1.1 christos distribute such modifications or work under the terms of Section 1
95 1.1 christos above, provided that you also meet all of these conditions:
96 1.1 christos
97 1.1 christos a) You must cause the modified files to carry prominent notices
98 1.1 christos stating that you changed the files and the date of any change.
99 1.1 christos
100 1.1 christos b) You must cause any work that you distribute or publish, that in
101 1.1 christos whole or in part contains or is derived from the Program or any
102 1.1 christos part thereof, to be licensed as a whole at no charge to all third
103 1.1 christos parties under the terms of this License.
104 1.1 christos
105 1.1 christos c) If the modified program normally reads commands interactively
106 1.1 christos when run, you must cause it, when started running for such
107 1.1 christos interactive use in the most ordinary way, to print or display an
108 1.1 christos announcement including an appropriate copyright notice and a
109 1.1 christos notice that there is no warranty (or else, saying that you provide
110 1.1 christos a warranty) and that users may redistribute the program under
111 1.1 christos these conditions, and telling the user how to view a copy of this
112 1.1 christos License. (Exception: if the Program itself is interactive but
113 1.1 christos does not normally print such an announcement, your work based on
114 1.1 christos the Program is not required to print an announcement.)
115 1.1 christos
117 1.1 christos These requirements apply to the modified work as a whole. If
118 1.1 christos identifiable sections of that work are not derived from the Program,
119 1.1 christos and can be reasonably considered independent and separate works in
120 1.1 christos themselves, then this License, and its terms, do not apply to those
121 1.1 christos sections when you distribute them as separate works. But when you
122 1.1 christos distribute the same sections as part of a whole which is a work based
123 1.1 christos on the Program, the distribution of the whole must be on the terms of
124 1.1 christos this License, whose permissions for other licensees extend to the
125 1.1 christos entire whole, and thus to each and every part regardless of who wrote it.
126 1.1 christos
127 1.1 christos Thus, it is not the intent of this section to claim rights or contest
128 1.1 christos your rights to work written entirely by you; rather, the intent is to
129 1.1 christos exercise the right to control the distribution of derivative or
130 1.1 christos collective works based on the Program.
131 1.1 christos
132 1.1 christos In addition, mere aggregation of another work not based on the Program
133 1.1 christos with the Program (or with a work based on the Program) on a volume of
134 1.1 christos a storage or distribution medium does not bring the other work under
135 1.1 christos the scope of this License.
136 1.1 christos
137 1.1 christos 3. You may copy and distribute the Program (or a work based on it,
138 1.1 christos under Section 2) in object code or executable form under the terms of
139 1.1 christos Sections 1 and 2 above provided that you also do one of the following:
140 1.1 christos
141 1.1 christos a) Accompany it with the complete corresponding machine-readable
142 1.1 christos source code, which must be distributed under the terms of Sections
143 1.1 christos 1 and 2 above on a medium customarily used for software interchange; or,
144 1.1 christos
145 1.1 christos b) Accompany it with a written offer, valid for at least three
146 1.1 christos years, to give any third party, for a charge no more than your
147 1.1 christos cost of physically performing source distribution, a complete
148 1.1 christos machine-readable copy of the corresponding source code, to be
149 1.1 christos distributed under the terms of Sections 1 and 2 above on a medium
150 1.1 christos customarily used for software interchange; or,
151 1.1 christos
152 1.1 christos c) Accompany it with the information you received as to the offer
153 1.1 christos to distribute corresponding source code. (This alternative is
154 1.1 christos allowed only for noncommercial distribution and only if you
155 1.1 christos received the program in object code or executable form with such
156 1.1 christos an offer, in accord with Subsection b above.)
157 1.1 christos
158 1.1 christos The source code for a work means the preferred form of the work for
159 1.1 christos making modifications to it. For an executable work, complete source
160 1.1 christos code means all the source code for all modules it contains, plus any
161 1.1 christos associated interface definition files, plus the scripts used to
162 1.1 christos control compilation and installation of the executable. However, as a
163 1.1 christos special exception, the source code distributed need not include
164 1.1 christos anything that is normally distributed (in either source or binary
165 1.1 christos form) with the major components (compiler, kernel, and so on) of the
166 1.1 christos operating system on which the executable runs, unless that component
167 1.1 christos itself accompanies the executable.
168 1.1 christos
169 1.1 christos If distribution of executable or object code is made by offering
170 1.1 christos access to copy from a designated place, then offering equivalent
171 1.1 christos access to copy the source code from the same place counts as
172 1.1 christos distribution of the source code, even though third parties are not
173 1.1 christos compelled to copy the source along with the object code.
174 1.1 christos
176 1.1 christos 4. You may not copy, modify, sublicense, or distribute the Program
177 1.1 christos except as expressly provided under this License. Any attempt
178 1.1 christos otherwise to copy, modify, sublicense or distribute the Program is
179 1.1 christos void, and will automatically terminate your rights under this License.
180 1.1 christos However, parties who have received copies, or rights, from you under
181 1.1 christos this License will not have their licenses terminated so long as such
182 1.1 christos parties remain in full compliance.
183 1.1 christos
184 1.1 christos 5. You are not required to accept this License, since you have not
185 1.1 christos signed it. However, nothing else grants you permission to modify or
186 1.1 christos distribute the Program or its derivative works. These actions are
187 1.1 christos prohibited by law if you do not accept this License. Therefore, by
188 1.1 christos modifying or distributing the Program (or any work based on the
189 1.1 christos Program), you indicate your acceptance of this License to do so, and
190 1.1 christos all its terms and conditions for copying, distributing or modifying
191 1.1 christos the Program or works based on it.
192 1.1 christos
193 1.1 christos 6. Each time you redistribute the Program (or any work based on the
194 1.1 christos Program), the recipient automatically receives a license from the
195 1.1 christos original licensor to copy, distribute or modify the Program subject to
196 1.1 christos these terms and conditions. You may not impose any further
197 1.1 christos restrictions on the recipients' exercise of the rights granted herein.
198 1.1 christos You are not responsible for enforcing compliance by third parties to
199 1.1 christos this License.
200 1.1 christos
201 1.1 christos 7. If, as a consequence of a court judgment or allegation of patent
202 1.1 christos infringement or for any other reason (not limited to patent issues),
203 1.1 christos conditions are imposed on you (whether by court order, agreement or
204 1.1 christos otherwise) that contradict the conditions of this License, they do not
205 1.1 christos excuse you from the conditions of this License. If you cannot
206 1.1 christos distribute so as to satisfy simultaneously your obligations under this
207 1.1 christos License and any other pertinent obligations, then as a consequence you
208 1.1 christos may not distribute the Program at all. For example, if a patent
209 1.1 christos license would not permit royalty-free redistribution of the Program by
210 1.1 christos all those who receive copies directly or indirectly through you, then
211 1.1 christos the only way you could satisfy both it and this License would be to
212 1.1 christos refrain entirely from distribution of the Program.
213 1.1 christos
214 1.1 christos If any portion of this section is held invalid or unenforceable under
215 1.1 christos any particular circumstance, the balance of the section is intended to
216 1.1 christos apply and the section as a whole is intended to apply in other
217 1.1 christos circumstances.
218 1.1 christos
219 1.1 christos It is not the purpose of this section to induce you to infringe any
220 1.1 christos patents or other property right claims or to contest validity of any
221 1.1 christos such claims; this section has the sole purpose of protecting the
222 1.1 christos integrity of the free software distribution system, which is
223 1.1 christos implemented by public license practices. Many people have made
224 1.1 christos generous contributions to the wide range of software distributed
225 1.1 christos through that system in reliance on consistent application of that
226 1.1 christos system; it is up to the author/donor to decide if he or she is willing
227 1.1 christos to distribute software through any other system and a licensee cannot
228 1.1 christos impose that choice.
229 1.1 christos
230 1.1 christos This section is intended to make thoroughly clear what is believed to
231 1.1 christos be a consequence of the rest of this License.
232 1.1 christos
234 1.1 christos 8. If the distribution and/or use of the Program is restricted in
235 1.1 christos certain countries either by patents or by copyrighted interfaces, the
236 1.1 christos original copyright holder who places the Program under this License
237 1.1 christos may add an explicit geographical distribution limitation excluding
238 1.1 christos those countries, so that distribution is permitted only in or among
239 1.1 christos countries not thus excluded. In such case, this License incorporates
240 1.1 christos the limitation as if written in the body of this License.
241 1.1 christos
242 1.1 christos 9. The Free Software Foundation may publish revised and/or new versions
243 1.1 christos of the General Public License from time to time. Such new versions will
244 1.1 christos be similar in spirit to the present version, but may differ in detail to
245 1.1 christos address new problems or concerns.
246 1.1 christos
247 1.1 christos Each version is given a distinguishing version number. If the Program
248 1.1 christos specifies a version number of this License which applies to it and "any
249 1.1 christos later version", you have the option of following the terms and conditions
250 1.1 christos either of that version or of any later version published by the Free
251 1.1 christos Software Foundation. If the Program does not specify a version number of
252 1.1 christos this License, you may choose any version ever published by the Free Software
253 1.1 christos Foundation.
254 1.1 christos
255 1.1 christos 10. If you wish to incorporate parts of the Program into other free
256 1.1 christos programs whose distribution conditions are different, write to the author
257 1.1 christos to ask for permission. For software which is copyrighted by the Free
258 1.1 christos Software Foundation, write to the Free Software Foundation; we sometimes
259 1.1 christos make exceptions for this. Our decision will be guided by the two goals
260 1.1 christos of preserving the free status of all derivatives of our free software and
261 1.1 christos of promoting the sharing and reuse of software generally.
262 1.1 christos
263 1.1 christos NO WARRANTY
264 1.1 christos
265 1.1 christos 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
266 1.1 christos FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
267 1.1 christos OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
268 1.1 christos PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
269 1.1 christos OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
270 1.1 christos MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
271 1.1 christos TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
272 1.1 christos PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
273 1.1 christos REPAIR OR CORRECTION.
274 1.1 christos
275 1.1 christos 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
276 1.1 christos WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
277 1.1 christos REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
278 1.1 christos INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
279 1.1 christos OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
280 1.1 christos TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
281 1.1 christos YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
282 1.1 christos PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
283 1.1 christos POSSIBILITY OF SUCH DAMAGES.
284 1.1 christos
285 1.1 christos END OF TERMS AND CONDITIONS
286 1.1 christos
288 1.1 christos How to Apply These Terms to Your New Programs
289 1.1 christos
290 1.1 christos If you develop a new program, and you want it to be of the greatest
291 1.1 christos possible use to the public, the best way to achieve this is to make it
292 1.1 christos free software which everyone can redistribute and change under these terms.
293 1.1 christos
294 1.1 christos To do so, attach the following notices to the program. It is safest
295 1.1 christos to attach them to the start of each source file to most effectively
296 1.1 christos convey the exclusion of warranty; and each file should have at least
297 1.1 christos the "copyright" line and a pointer to where the full notice is found.
298 1.1 christos
299 1.1 christos <one line to give the program's name and a brief idea of what it does.>
300 1.1 christos Copyright (C) 19yy <name of author>
301 1.1 christos
302 1.1 christos This program is free software; you can redistribute it and/or modify
303 1.1 christos it under the terms of the GNU General Public License as published by
304 1.1 christos the Free Software Foundation; either version 2 of the License, or
305 1.1 christos (at your option) any later version.
306 1.1 christos
307 1.1 christos This program is distributed in the hope that it will be useful,
308 1.1 christos but WITHOUT ANY WARRANTY; without even the implied warranty of
309 1.1 christos MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
310 1.1 christos GNU General Public License for more details.
311 1.1 christos
312 1.1 christos You should have received a copy of the GNU General Public License
313 1.1 christos along with this program; if not, write to the Free Software Foundation,
314 1.1 christos Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
315 1.1 christos
316 1.1 christos
317 1.1 christos Also add information on how to contact you by electronic and paper mail.
318 1.1 christos
319 1.1 christos If the program is interactive, make it output a short notice like this
320 1.1 christos when it starts in an interactive mode:
321 1.1 christos
322 1.1 christos Gnomovision version 69, Copyright (C) 19yy name of author
323 1.1 christos Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
324 1.1 christos This is free software, and you are welcome to redistribute it
325 1.1 christos under certain conditions; type `show c' for details.
326 1.1 christos
327 1.1 christos The hypothetical commands `show w' and `show c' should show the appropriate
328 1.1 christos parts of the General Public License. Of course, the commands you use may
329 1.1 christos be called something other than `show w' and `show c'; they could even be
330 1.1 christos mouse-clicks or menu items--whatever suits your program.
331 1.1 christos
332 1.1 christos You should also get your employer (if you work as a programmer) or your
333 1.1 christos school, if any, to sign a "copyright disclaimer" for the program, if
334 1.1 christos necessary. Here is a sample; alter the names:
335 1.1 christos
336 1.1 christos Yoyodyne, Inc., hereby disclaims all copyright interest in the program
337 1.1 christos `Gnomovision' (which makes passes at compilers) written by James Hacker.

341 1.1 christos
342 This General Public License does not permit incorporating your program into
343 proprietary programs. If your program is a subroutine library, you may
344 consider it more useful to permit linking proprietary applications with the
345 library. If this is what you want to do, use the GNU Library General
346 Public License instead of this License.
347
