16 1. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
17 How to use this License for your documents
21 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple
22 Place - Suite 330, Boston, MA 02111-1307, USA Everyone is permitted
23 to copy and distribute verbatim copies of this license document, but
24 changing it is not allowed.
28 The licenses for most software are designed to take away your freedom
29 to share and change it. By contrast, the GNU General Public License is
30 intended to guarantee your freedom to share and change free
31 software--to make sure the software is free for all its users. This
32 General Public License applies to most of the Free Software
33 Foundation's software and to any other program whose authors commit to
34 using it. (Some other Free Software Foundation software is covered by
35 the GNU Library General Public License instead.) You can apply it to
38 When we speak of free software, we are referring to freedom, not price.
39 Our General Public Licenses are designed to make sure that you have the
40 freedom to distribute copies of free software (and charge for this
41 service if you wish), that you receive source code or can get it if you
42 want it, that you can change the software or use pieces of it in new
43 free programs; and that you know you can do these things.
45 To protect your rights, we need to make restrictions that forbid anyone
46 to deny you these rights or to ask you to surrender the rights. These
47 restrictions translate to certain responsibilities for you if you
48 distribute copies of the software, or if you modify it.
50 For example, if you distribute copies of such a program, whether gratis
51 or for a fee, you must give the recipients all the rights that you
52 have. You must make sure that they, too, receive or can get the source
53 code. And you must show them these terms so they know their rights.
55 We protect your rights with two steps: (1) copyright the software, and
56 (2) offer you this license which gives you legal permission to copy,
57 distribute and/or modify the software.
59 Also, for each author's protection and ours, we want to make certain
60 that everyone understands that there is no warranty for this free
61 software. If the software is modified by someone else and passed on, we
62 want its recipients to know that what they have is not the original, so
63 that any problems introduced by others will not reflect on the original
66 Finally, any free program is threatened constantly by software patents.
67 We wish to avoid the danger that redistributors of a free program will
68 individually obtain patent licenses, in effect making the program
69 proprietary. To prevent this, we have made it clear that any patent
70 must be licensed for everyone's free use or not licensed at all.
72 The precise terms and conditions for copying, distribution and
75 1. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
77 0. This License applies to any program or other work which contains a
78 notice placed by the copyright holder saying it may be distributed
79 under the terms of this General Public License. The "Program", below,
80 refers to any such program or work, and a "work based on the Program"
81 means either the Program or any derivative work under copyright law:
82 that is to say, a work containing the Program or a portion of it,
83 either verbatim or with modifications and/or translated into another
84 language. (Hereinafter, translation is included without limitation in
85 the term "modification".) Each licensee is addressed as "you".
87 Activities other than copying, distribution and modification are not
88 covered by this License; they are outside its scope. The act of running
89 the Program is not restricted, and the output from the Program is
90 covered only if its contents constitute a work based on the Program
91 (independent of having been made by running the Program). Whether that
92 is true depends on what the Program does.
94 1. You may copy and distribute verbatim copies of the Program's source
95 code as you receive it, in any medium, provided that you conspicuously
96 and appropriately publish on each copy an appropriate copyright notice
97 and disclaimer of warranty; keep intact all the notices that refer to
98 this License and to the absence of any warranty; and give any other
99 recipients of the Program a copy of this License along with the
102 You may charge a fee for the physical act of transferring a copy, and
103 you may at your option offer warranty protection in exchange for a fee.
105 2. You may modify your copy or copies of the Program or any portion of
106 it, thus forming a work based on the Program, and copy and distribute
107 such modifications or work under the terms of Section 1 above, provided
108 that you also meet all of these conditions:
110 * a) You must cause the modified files to carry prominent notices
111 stating that you changed the files and the date of any change.
113 * b) You must cause any work that you distribute or publish, that in
114 whole or in part contains or is derived from the Program or any part
115 thereof, to be licensed as a whole at no charge to all third parties
116 under the terms of this License.
118 * c) If the modified program normally reads commands interactively when
119 run, you must cause it, when started running for such interactive use
120 in the most ordinary way, to print or display an announcement including
121 an appropriate copyright notice and a notice that there is no warranty
122 (or else, saying that you provide a warranty) and that users may
123 redistribute the program under these conditions, and telling the user
124 how to view a copy of this License. (Exception: if the Program itself
125 is interactive but does not normally print such an announcement, your
126 work based on the Program is not required to print an announcement.)
128 These requirements apply to the modified work as a whole. If
129 identifiable sections of that work are not derived from the Program,
130 and can be reasonably considered independent and separate works in
131 themselves, then this License, and its terms, do not apply to those
132 sections when you distribute them as separate works. But when you
133 distribute the same sections as part of a whole which is a work based
134 on the Program, the distribution of the whole must be on the terms of
135 this License, whose permissions for other licensees extend to the
136 entire whole, and thus to each and every part regardless of who wrote
139 Thus, it is not the intent of this section to claim rights or contest
140 your rights to work written entirely by you; rather, the intent is to
141 exercise the right to control the distribution of derivative or
142 collective works based on the Program.
144 In addition, mere aggregation of another work not based on the Program
145 with the Program (or with a work based on the Program) on a volume of a
146 storage or distribution medium does not bring the other work under the
147 scope of this License.
149 3. You may copy and distribute the Program (or a work based on it,
150 under Section 2) in object code or executable form under the terms of
151 Sections 1 and 2 above provided that you also do one of the following:
153 * a) Accompany it with the complete corresponding machine-readable
154 source code, which must be distributed under the terms of Sections 1
155 and 2 above on a medium customarily used for software interchange; or,
157 * b) Accompany it with a written offer, valid for at least three years,
158 to give any third party, for a charge no more than your cost of
159 physically performing source distribution, a complete machine-readable
160 copy of the corresponding source code, to be distributed under the
161 terms of Sections 1 and 2 above on a medium customarily used for
162 software interchange; or,
164 * c) Accompany it with the information you received as to the offer to
165 distribute corresponding source code. (This alternative is allowed only
166 for noncommercial distribution and only if you received the program in
167 object code or executable form with such an offer, in accord with
170 The source code for a work means the preferred form of the work for
171 making modifications to it. For an executable work, complete source
172 code means all the source code for all modules it contains, plus any
173 associated interface definition files, plus the scripts used to control
174 compilation and installation of the executable. However, as a special
175 exception, the source code distributed need not include anything that
176 is normally distributed (in either source or binary form) with the
177 major components (compiler, kernel, and so on) of the operating system
178 on which the executable runs, unless that component itself accompanies
181 If distribution of executable or object code is made by offering access
182 to copy from a designated place, then offering equivalent access to
183 copy the source code from the same place counts as distribution of the
184 source code, even though third parties are not compelled to copy the
185 source along with the object code.
187 4. You may not copy, modify, sublicense, or distribute the Program
188 except as expressly provided under this License. Any attempt otherwise
189 to copy, modify, sublicense or distribute the Program is void, and will
190 automatically terminate your rights under this License. However,
191 parties who have received copies, or rights, from you under this
192 License will not have their licenses terminated so long as such parties
193 remain in full compliance.
195 5. You are not required to accept this License, since you have not
196 signed it. However, nothing else grants you permission to modify or
197 distribute the Program or its derivative works. These actions are
198 prohibited by law if you do not accept this License. Therefore, by
199 modifying or distributing the Program (or any work based on the
200 Program), you indicate your acceptance of this License to do so, and
201 all its terms and conditions for copying, distributing or modifying the
202 Program or works based on it.
204 6. Each time you redistribute the Program (or any work based on the
205 Program), the recipient automatically receives a license from the
206 original licensor to copy, distribute or modify the Program subject to
207 these terms and conditions. You may not impose any further restrictions
208 on the recipients' exercise of the rights granted herein. You are not
209 responsible for enforcing compliance by third parties to this License.
211 7. If, as a consequence of a court judgment or allegation of patent
212 infringement or for any other reason (not limited to patent issues),
213 conditions are imposed on you (whether by court order, agreement or
214 otherwise) that contradict the conditions of this License, they do not
215 excuse you from the conditions of this License. If you cannot
216 distribute so as to satisfy simultaneously your obligations under this
217 License and any other pertinent obligations, then as a consequence you
218 may not distribute the Program at all. For example, if a patent license
219 would not permit royalty-free redistribution of the Program by all
220 those who receive copies directly or indirectly through you, then the
221 only way you could satisfy both it and this License would be to refrain
222 entirely from distribution of the Program.
224 If any portion of this section is held invalid or unenforceable under
225 any particular circumstance, the balance of the section is intended to
226 apply and the section as a whole is intended to apply in other
229 It is not the purpose of this section to induce you to infringe any
230 patents or other property right claims or to contest validity of any
231 such claims; this section has the sole purpose of protecting the
232 integrity of the free software distribution system, which is
233 implemented by public license practices. Many people have made generous
234 contributions to the wide range of software distributed through that
235 system in reliance on consistent application of that system; it is up
236 to the author/donor to decide if he or she is willing to distribute
237 software through any other system and a licensee cannot impose that
240 This section is intended to make thoroughly clear what is believed to
241 be a consequence of the rest of this License.
243 8. If the distribution and/or use of the Program is restricted in
244 certain countries either by patents or by copyrighted interfaces, the
245 original copyright holder who places the Program under this License may
246 add an explicit geographical distribution limitation excluding those
247 countries, so that distribution is permitted only in or among countries
248 not thus excluded. In such case, this License incorporates the
249 limitation as if written in the body of this License.
251 9. The Free Software Foundation may publish revised and/or new versions
252 of the General Public License from time to time. Such new versions will
253 be similar in spirit to the present version, but may differ in detail
254 to address new problems or concerns.
256 Each version is given a distinguishing version number. If the Program
257 specifies a version number of this License which applies to it and "any
258 later version", you have the option of following the terms and
259 conditions either of that version or of any later version published by
260 the Free Software Foundation. If the Program does not specify a version
261 number of this License, you may choose any version ever published by
262 the Free Software Foundation.
264 10. If you wish to incorporate parts of the Program into other free
265 programs whose distribution conditions are different, write to the
266 author to ask for permission. For software which is copyrighted by the
267 Free Software Foundation, write to the Free Software Foundation; we
268 sometimes make exceptions for this. Our decision will be guided by the
269 two goals of preserving the free status of all derivatives of our free
270 software and of promoting the sharing and reuse of software generally.
274 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
275 WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
276 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
277 OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND,
278 EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
279 WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
280 ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH
281 YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
282 NECESSARY SERVICING, REPAIR OR CORRECTION.
284 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
285 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
286 AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU
287 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
288 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
289 PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
290 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
291 FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF
292 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
295 END OF TERMS AND CONDITIONS
297 How to use this License for your documents
299 If you develop a new program, and you want it to be of the greatest
300 possible use to the public, the best way to achieve this is to make it
301 free software which everyone can redistribute and change under these
304 To do so, attach the following notices to the program. It is safest to
305 attach them to the start of each source file to most effectively convey
306 the exclusion of warranty; and each file should have at least the
307 "copyright" line and a pointer to where the full notice is found.
309 one line to give the program's name and an idea of what it does.
310 Copyright (C) yyyy name of author This program is free software; you
311 can redistribute it and/or modify it under the terms of the GNU
312 General Public License as published by the Free Software Foundation;
313 either version 2 of the License, or (at your option) any later
314 version. This program is distributed in the hope that it will be
315 useful, but WITHOUT ANY WARRANTY; without even the implied warranty
316 of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
317 General Public License for more details. You should have received a
318 copy of the GNU General Public License along with this program; if
319 not, write to the Free Software Foundation, Inc., 59 Temple Place -
320 Suite 330, Boston, MA 02111-1307, USA.
322 Also add information on how to contact you by electronic and paper
325 If the program is interactive, make it output a short notice like this
326 when it starts in an interactive mode:
327 Gnomovision version 69, Copyright (C) year name of author
328 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This
329 is free software, and you are welcome to redistribute it under certain
330 conditions; type `show c' for details.
332 The hypothetical commands `show w' and `show c' should show the
333 appropriate parts of the General Public License. Of course, the
334 commands you use may be called something other than `show w' and `show
335 c'; they could even be mouse-clicks or menu items--whatever suits your
338 You should also get your employer (if you work as a programmer) or your
339 school, if any, to sign a "copyright disclaimer" for the program, if
340 necessary. Here is a sample; alter the names:
342 Yoyodyne, Inc., hereby disclaims all copyright interest in the
343 program `Gnomovision' (which makes passes at compilers) written by
346 signature of Ty Coon, 1 April 1989 Ty Coon, President of Vice
348 This General Public License does not permit incorporating your program
349 into proprietary programs. If your program is a subroutine library, you
350 may consider it more useful to permit linking proprietary applications
351 with the library. If this is what you want to do, use the GNU Library
352 General Public License instead of this License.
