44 Everyone is permitted to copy and distribute verbatim copies
45 of this license document, but changing it is not allowed.
46
47 Preamble
48
49 The licenses for most software are designed to take away your
50 freedom to share and change it. By contrast, the GNU General Public
51 License is intended to guarantee your freedom to share and change free
52 software--to make sure the software is free for all its users. This
53 General Public License applies to most of the Free Software
54 Foundation's software and to any other program whose authors commit to
55 using it. (Some other Free Software Foundation software is covered by
56 the GNU Library General Public License instead.) You can apply it to
57 your programs, too.
58
59 When we speak of free software, we are referring to freedom, not
60 price. Our General Public Licenses are designed to make sure that you
61 have the freedom to distribute copies of free software (and charge for
62 this service if you wish), that you receive source code or can get it
63 if you want it, that you can change the software or use pieces of it
64 in new free programs; and that you know you can do these things.
65
66 To protect your rights, we need to make restrictions that forbid
67 anyone to deny you these rights or to ask you to surrender the rights.
68 These restrictions translate to certain responsibilities for you if you
69 distribute copies of the software, or if you modify it.
70
71 For example, if you distribute copies of such a program, whether
72 gratis or for a fee, you must give the recipients all the rights that
73 you have. You must make sure that they, too, receive or can get the
74 source code. And you must show them these terms so they know their
75 rights.
76
77 We protect your rights with two steps: (1) copyright the software, and
78 (2) offer you this license which gives you legal permission to copy,
79 distribute and/or modify the software.
80
81 Also, for each author's protection and ours, we want to make certain
82 that everyone understands that there is no warranty for this free
83 software. If the software is modified by someone else and passed on, we
84 want its recipients to know that what they have is not the original, so
85 that any problems introduced by others will not reflect on the original
86 authors' reputations.
87
88 Finally, any free program is threatened constantly by software
89 patents. We wish to avoid the danger that redistributors of a free
90 program will individually obtain patent licenses, in effect making the
91 program proprietary. To prevent this, we have made it clear that any
92 patent must be licensed for everyone's free use or not licensed at all.
93
94 The precise terms and conditions for copying, distribution and
95 modification follow.
96
97 GNU GENERAL PUBLIC LICENSE
98 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
99
100 0. This License applies to any program or other work which contains
101 a notice placed by the copyright holder saying it may be distributed
102 under the terms of this General Public License. The "Program", below,
103 refers to any such program or work, and a "work based on the Program"
104 means either the Program or any derivative work under copyright law:
105 that is to say, a work containing the Program or a portion of it,
106 either verbatim or with modifications and/or translated into another
107 language. (Hereinafter, translation is included without limitation in
108 the term "modification".) Each licensee is addressed as "you".
109
110 Activities other than copying, distribution and modification are not
111 covered by this License; they are outside its scope. The act of
112 running the Program is not restricted, and the output from the Program
113 is covered only if its contents constitute a work based on the
114 Program (independent of having been made by running the Program).
115 Whether that is true depends on what the Program does.
116
117 1. You may copy and distribute verbatim copies of the Program's
118 source code as you receive it, in any medium, provided that you
119 conspicuously and appropriately publish on each copy an appropriate
120 copyright notice and disclaimer of warranty; keep intact all the
121 notices that refer to this License and to the absence of any warranty;
122 and give any other recipients of the Program a copy of this License
123 along with the Program.
124
125 You may charge a fee for the physical act of transferring a copy, and
126 you may at your option offer warranty protection in exchange for a fee.
127
128 2. You may modify your copy or copies of the Program or any portion
129 of it, thus forming a work based on the Program, and copy and
130 distribute such modifications or work under the terms of Section 1
131 above, provided that you also meet all of these conditions:
132
133 a) You must cause the modified files to carry prominent notices
134 stating that you changed the files and the date of any change.
135
136 b) You must cause any work that you distribute or publish, that in
137 whole or in part contains or is derived from the Program or any
138 part thereof, to be licensed as a whole at no charge to all third
139 parties under the terms of this License.
140
141 c) If the modified program normally reads commands interactively
142 when run, you must cause it, when started running for such
143 interactive use in the most ordinary way, to print or display an
144 announcement including an appropriate copyright notice and a
145 notice that there is no warranty (or else, saying that you provide
146 a warranty) and that users may redistribute the program under
147 these conditions, and telling the user how to view a copy of this
148 License. (Exception: if the Program itself is interactive but
149 does not normally print such an announcement, your work based on
150 the Program is not required to print an announcement.)
151
152 These requirements apply to the modified work as a whole. If
153 identifiable sections of that work are not derived from the Program,
154 and can be reasonably considered independent and separate works in
155 themselves, then this License, and its terms, do not apply to those
156 sections when you distribute them as separate works. But when you
157 distribute the same sections as part of a whole which is a work based
158 on the Program, the distribution of the whole must be on the terms of
159 this License, whose permissions for other licensees extend to the
160 entire whole, and thus to each and every part regardless of who wrote it.
161
162 Thus, it is not the intent of this section to claim rights or contest
163 your rights to work written entirely by you; rather, the intent is to
164 exercise the right to control the distribution of derivative or
165 collective works based on the Program.
166
167 In addition, mere aggregation of another work not based on the Program
168 with the Program (or with a work based on the Program) on a volume of
169 a storage or distribution medium does not bring the other work under
170 the scope of this License.
171
172 3. You may copy and distribute the Program (or a work based on it,
173 under Section 2) in object code or executable form under the terms of
174 Sections 1 and 2 above provided that you also do one of the following:
175
176 a) Accompany it with the complete corresponding machine-readable
177 source code, which must be distributed under the terms of Sections
178 1 and 2 above on a medium customarily used for software interchange; or,
179
180 b) Accompany it with a written offer, valid for at least three
181 years, to give any third party, for a charge no more than your
182 cost of physically performing source distribution, a complete
183 machine-readable copy of the corresponding source code, to be
184 distributed under the terms of Sections 1 and 2 above on a medium
185 customarily used for software interchange; or,
186
187 c) Accompany it with the information you received as to the offer
188 to distribute corresponding source code. (This alternative is
189 allowed only for noncommercial distribution and only if you
190 received the program in object code or executable form with such
191 an offer, in accord with Subsection b above.)
192
193 The source code for a work means the preferred form of the work for
194 making modifications to it. For an executable work, complete source
195 code means all the source code for all modules it contains, plus any
196 associated interface definition files, plus the scripts used to
197 control compilation and installation of the executable. However, as a
198 special exception, the source code distributed need not include
199 anything that is normally distributed (in either source or binary
200 form) with the major components (compiler, kernel, and so on) of the
201 operating system on which the executable runs, unless that component
202 itself accompanies the executable.
203
204 If distribution of executable or object code is made by offering
205 access to copy from a designated place, then offering equivalent
206 access to copy the source code from the same place counts as
207 distribution of the source code, even though third parties are not
208 compelled to copy the source along with the object code.
209
210 4. You may not copy, modify, sublicense, or distribute the Program
211 except as expressly provided under this License. Any attempt
212 otherwise to copy, modify, sublicense or distribute the Program is
213 void, and will automatically terminate your rights under this License.
214 However, parties who have received copies, or rights, from you under
215 this License will not have their licenses terminated so long as such
216 parties remain in full compliance.
217
218 5. You are not required to accept this License, since you have not
219 signed it. However, nothing else grants you permission to modify or
220 distribute the Program or its derivative works. These actions are
221 prohibited by law if you do not accept this License. Therefore, by
222 modifying or distributing the Program (or any work based on the
223 Program), you indicate your acceptance of this License to do so, and
224 all its terms and conditions for copying, distributing or modifying
225 the Program or works based on it.
226
227 6. Each time you redistribute the Program (or any work based on the
228 Program), the recipient automatically receives a license from the
229 original licensor to copy, distribute or modify the Program subject to
230 these terms and conditions. You may not impose any further
231 restrictions on the recipients' exercise of the rights granted herein.
232 You are not responsible for enforcing compliance by third parties to
233 this License.
234
235 7. If, as a consequence of a court judgment or allegation of patent
236 infringement or for any other reason (not limited to patent issues),
237 conditions are imposed on you (whether by court order, agreement or
238 otherwise) that contradict the conditions of this License, they do not
239 excuse you from the conditions of this License. If you cannot
240 distribute so as to satisfy simultaneously your obligations under this
241 License and any other pertinent obligations, then as a consequence you
242 may not distribute the Program at all. For example, if a patent
243 license would not permit royalty-free redistribution of the Program by
244 all those who receive copies directly or indirectly through you, then
245 the only way you could satisfy both it and this License would be to
246 refrain entirely from distribution of the Program.
247
248 If any portion of this section is held invalid or unenforceable under
249 any particular circumstance, the balance of the section is intended to
250 apply and the section as a whole is intended to apply in other
251 circumstances.
252
253 It is not the purpose of this section to induce you to infringe any
254 patents or other property right claims or to contest validity of any
255 such claims; this section has the sole purpose of protecting the
256 integrity of the free software distribution system, which is
257 implemented by public license practices. Many people have made
258 generous contributions to the wide range of software distributed
259 through that system in reliance on consistent application of that
260 system; it is up to the author/donor to decide if he or she is willing
261 to distribute software through any other system and a licensee cannot
262 impose that choice.
263
264 This section is intended to make thoroughly clear what is believed to
265 be a consequence of the rest of this License.
266
267 8. If the distribution and/or use of the Program is restricted in
268 certain countries either by patents or by copyrighted interfaces, the
269 original copyright holder who places the Program under this License
270 may add an explicit geographical distribution limitation excluding
271 those countries, so that distribution is permitted only in or among
272 countries not thus excluded. In such case, this License incorporates
273 the limitation as if written in the body of this License.
274
275 9. The Free Software Foundation may publish revised and/or new versions
276 of the General Public License from time to time. Such new versions will
277 be similar in spirit to the present version, but may differ in detail to
278 address new problems or concerns.
279
280 Each version is given a distinguishing version number. If the Program
281 specifies a version number of this License which applies to it and "any
282 later version", you have the option of following the terms and conditions
283 either of that version or of any later version published by the Free
284 Software Foundation. If the Program does not specify a version number of
285 this License, you may choose any version ever published by the Free Software
286 Foundation.
287
288 10. If you wish to incorporate parts of the Program into other free
289 programs whose distribution conditions are different, write to the author
290 to ask for permission. For software which is copyrighted by the Free
291 Software Foundation, write to the Free Software Foundation; we sometimes
292 make exceptions for this. Our decision will be guided by the two goals
293 of preserving the free status of all derivatives of our free software and
294 of promoting the sharing and reuse of software generally.
295
296 NO WARRANTY
297
298 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
299 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
300 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
301 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
302 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
303 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
304 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
305 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
306 REPAIR OR CORRECTION.
307
308 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
309 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
310 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
311 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
312 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
313 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
314 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
315 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
316 POSSIBILITY OF SUCH DAMAGES.
317
318 END OF TERMS AND CONDITIONS
319
320 How to Apply These Terms to Your New Programs
321
322 If you develop a new program, and you want it to be of the greatest
323 possible use to the public, the best way to achieve this is to make it
324 free software which everyone can redistribute and change under these terms.
325
326 To do so, attach the following notices to the program. It is safest
327 to attach them to the start of each source file to most effectively
328 convey the exclusion of warranty; and each file should have at least
329 the "copyright" line and a pointer to where the full notice is found.
330
331 <one line to give the program's name and a brief idea of what it does.>
332 Copyright (C) <year> <name of author>
333
334 This program is free software; you can redistribute it and/or modify
335 it under the terms of the GNU General Public License as published by
336 the Free Software Foundation; either version 2 of the License, or
337 (at your option) any later version.
338
339 This program is distributed in the hope that it will be useful,
340 but WITHOUT ANY WARRANTY; without even the implied warranty of
341 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
342 GNU General Public License for more details.
343
344 You should have received a copy of the GNU General Public License
345 along with this program; if not, write to the Free Software
346 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
347
348
349 Also add information on how to contact you by electronic and paper mail.
350
351 If the program is interactive, make it output a short notice like this
352 when it starts in an interactive mode:
353
354 Gnomovision version 69, Copyright (C) year name of author
355 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type \`show w\'.
356 This is free software, and you are welcome to redistribute it
357 under certain conditions; type \`show c\' for details.
358
359 The hypothetical commands \`show w\' and \`show c\' should show the appropriate
360 parts of the General Public License. Of course, the commands you use may
361 be called something other than \`show w\' and \`show c\'; they could even be
362 mouse-clicks or menu items--whatever suits your program.
363
364 You should also get your employer (if you work as a programmer) or your
365 school, if any, to sign a \"copyright disclaimer\" for the program, if
366 necessary. Here is a sample; alter the names:
367
368 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
369 \`Gnomovision\' (which makes passes at compilers) written by James Hacker.

373
374 This General Public License does not permit incorporating your program into
375 proprietary programs. If your program is a subroutine library, you may
376 consider it more useful to permit linking proprietary applications with the
377 library. If this is what you want to do, use the GNU Library General
378 Public License instead of this License.
