34 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
35 675 Mass Ave, Cambridge, MA 02139, USA
37 Everyone is permitted to copy and distribute verbatim copies
38 of this license document, but changing it is not allowed.
43 The licenses for most software are designed to take away your
44 freedom to share and change it. By contrast, the GNU General Public
45 License is intended to guarantee your freedom to share and change free
46 software--to make sure the software is free for all its users. This
47 General Public License applies to most of the Free Software
48 Foundation's software and to any other program whose authors commit to
49 using it. (Some other Free Software Foundation software is covered by
50 the GNU Library General Public License instead.) You can apply it to
53 When we speak of free software, we are referring to freedom, not
54 price. Our General Public Licenses are designed to make sure that you
55 have the freedom to distribute copies of free software (and charge for
56 this service if you wish), that you receive source code or can get it
57 if you want it, that you can change the software or use pieces of it in
58 new free programs; and that you know you can do these things.
60 To protect your rights, we need to make restrictions that forbid
61 anyone to deny you these rights or to ask you to surrender the rights.
62 These restrictions translate to certain responsibilities for you if you
63 distribute copies of the software, or if you modify it.
65 For example, if you distribute copies of such a program, whether
66 gratis or for a fee, you must give the recipients all the rights that
67 you have. You must make sure that they, too, receive or can get the
68 source code. And you must show them these terms so they know their
71 We protect your rights with two steps: (1) copyright the software,
72 and (2) offer you this license which gives you legal permission to copy,
73 distribute and/or modify the software.
75 Also, for each author's protection and ours, we want to make certain
76 that everyone understands that there is no warranty for this free
77 software. If the software is modified by someone else and passed on, we
78 want its recipients to know that what they have is not the original, so
79 that any problems introduced by others will not reflect on the original
82 Finally, any free program is threatened constantly by software
83 patents. We wish to avoid the danger that redistributors of a free
84 program will individually obtain patent licenses, in effect making the
85 program proprietary. To prevent this, we have made it clear that any
86 patent must be licensed for everyone's free use or not licensed at all.
88 The precise terms and conditions for copying, distribution and
91 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
93 1. This License applies to any program or other work which contains a
94 notice placed by the copyright holder saying it may be distributed
95 under the terms of this General Public License. The "Program",
96 below, refers to any such program or work, and a "work based on
97 the Program" means either the Program or any derivative work under
98 copyright law: that is to say, a work containing the Program or a
99 portion of it, either verbatim or with modifications and/or
100 translated into another language. (Hereinafter, translation is
101 included without limitation in the term "modification".) Each
102 licensee is addressed as "you".
104 Activities other than copying, distribution and modification are
105 not covered by this License; they are outside its scope. The act
106 of running the Program is not restricted, and the output from the
107 Program is covered only if its contents constitute a work based on
108 the Program (independent of having been made by running the
109 Program). Whether that is true depends on what the Program does.
111 2. You may copy and distribute verbatim copies of the Program's
112 source code as you receive it, in any medium, provided that you
113 conspicuously and appropriately publish on each copy an appropriate
114 copyright notice and disclaimer of warranty; keep intact all the
115 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
117 this License along with the Program.
119 You may charge a fee for the physical act of transferring a copy,
120 and you may at your option offer warranty protection in exchange
123 3. You may modify your copy or copies of the Program or any portion
124 of it, thus forming a work based on the Program, and copy and
125 distribute such modifications or work under the terms of Section 1
126 above, provided that you also meet all of these conditions:
128 a. You must cause the modified files to carry prominent notices
129 stating that you changed the files and the date of any change.
131 b. You must cause any work that you distribute or publish, that
132 in whole or in part contains or is derived from the Program
133 or any part thereof, to be licensed as a whole at no charge
134 to all third parties under the terms of this License.
136 c. If the modified program normally reads commands interactively
137 when run, you must cause it, when started running for such
138 interactive use in the most ordinary way, to print or display
139 an announcement including an appropriate copyright notice and
140 a notice that there is no warranty (or else, saying that you
141 provide a warranty) and that users may redistribute the
142 program under these conditions, and telling the user how to
143 view a copy of this License. (Exception: if the Program
144 itself is interactive but does not normally print such an
145 announcement, your work based on the Program is not required
146 to print an announcement.)
148 These requirements apply to the modified work as a whole. If
149 identifiable sections of that work are not derived from the
150 Program, and can be reasonably considered independent and separate
151 works in themselves, then this License, and its terms, do not
152 apply to those sections when you distribute them as separate
153 works. But when you distribute the same sections as part of a
154 whole which is a work based on the Program, the distribution of
155 the whole must be on the terms of this License, whose permissions
156 for other licensees extend to the entire whole, and thus to each
157 and every part regardless of who wrote it.
159 Thus, it is not the intent of this section to claim rights or
160 contest your rights to work written entirely by you; rather, the
161 intent is to exercise the right to control the distribution of
162 derivative or collective works based on the Program.
164 In addition, mere aggregation of another work not based on the
165 Program with the Program (or with a work based on the Program) on
166 a volume of a storage or distribution medium does not bring the
167 other work under the scope of this License.
169 4. You may copy and distribute the Program (or a work based on it,
170 under Section 2) in object code or executable form under the terms
171 of Sections 1 and 2 above provided that you also do one of the
174 a. Accompany it with the complete corresponding machine-readable
175 source code, which must be distributed under the terms of
176 Sections 1 and 2 above on a medium customarily used for
177 software interchange; or,
179 b. Accompany it with a written offer, valid for at least three
180 years, to give any third party, for a charge no more than your
181 cost of physically performing source distribution, a complete
182 machine-readable copy of the corresponding source code, to be
183 distributed under the terms of Sections 1 and 2 above on a
184 medium customarily used for software interchange; or,
186 c. Accompany it with the information you received as to the offer
187 to distribute corresponding source code. (This alternative is
188 allowed only for noncommercial distribution and only if you
189 received the program in object code or executable form with
190 such an offer, in accord with Subsection b above.)
192 The source code for a work means the preferred form of the work for
193 making modifications to it. For an executable work, complete
194 source code means all the source code for all modules it contains,
195 plus any associated interface definition files, plus the scripts
196 used to control compilation and installation of the executable.
197 However, as a special exception, the source code distributed need
198 not include anything that is normally distributed (in either
199 source or binary form) with the major components (compiler,
200 kernel, and so on) of the operating system on which the executable
201 runs, unless that component itself accompanies the executable.
203 If distribution of executable or object code is made by offering
204 access to copy from a designated place, then offering equivalent
205 access to copy the source code from the same place counts as
206 distribution of the source code, even though third parties are not
207 compelled to copy the source along with the object code.
209 5. You may not copy, modify, sublicense, or distribute the Program
210 except as expressly provided under this License. Any attempt
211 otherwise to copy, modify, sublicense or distribute the Program is
212 void, and will automatically terminate your rights under this
213 License. However, parties who have received copies, or rights,
214 from you under this License will not have their licenses
215 terminated so long as such parties remain in full compliance.
217 6. You are not required to accept this License, since you have not
218 signed it. However, nothing else grants you permission to modify
219 or distribute the Program or its derivative works. These actions
220 are prohibited by law if you do not accept this License.
221 Therefore, by modifying or distributing the Program (or any work
222 based on the Program), you indicate your acceptance of this
223 License to do so, and all its terms and conditions for copying,
224 distributing or modifying the Program or works based on it.
226 7. Each time you redistribute the Program (or any work based on the
227 Program), the recipient automatically receives a license from the
228 original licensor to copy, distribute or modify the Program
229 subject to these terms and conditions. You may not impose any
230 further restrictions on the recipients' exercise of the rights
231 granted herein. You are not responsible for enforcing compliance
232 by third parties to this License.
234 8. If, as a consequence of a court judgment or allegation of patent
235 infringement or for any other reason (not limited to patent
236 issues), conditions are imposed on you (whether by court order,
237 agreement or otherwise) that contradict the conditions of this
238 License, they do not excuse you from the conditions of this
239 License. If you cannot distribute so as to satisfy simultaneously
240 your obligations under this License and any other pertinent
241 obligations, then as a consequence you may not distribute the
242 Program at all. For example, if a patent license would not permit
243 royalty-free redistribution of the Program by all those who
244 receive copies directly or indirectly through you, then the only
245 way you could satisfy both it and this License would be to refrain
246 entirely from distribution of the Program.
248 If any portion of this section is held invalid or unenforceable
249 under any particular circumstance, the balance of the section is
250 intended to apply and the section as a whole is intended to apply
251 in other circumstances.
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
255 any such claims; this section has the sole purpose of protecting
256 the 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
261 willing to distribute software through any other system and a
262 licensee cannot impose that choice.
264 This section is intended to make thoroughly clear what is believed
265 to be a consequence of the rest of this License.
267 9. If the distribution and/or use of the Program is restricted in
268 certain countries either by patents or by copyrighted interfaces,
269 the original copyright holder who places the Program under this
270 License may add an explicit geographical distribution limitation
271 excluding those countries, so that distribution is permitted only
272 in or among countries not thus excluded. In such case, this
273 License incorporates the limitation as if written in the body of
276 10. The Free Software Foundation may publish revised and/or new
277 versions of the General Public License from time to time. Such
278 new versions will be similar in spirit to the present version, but
279 may differ in detail to address new problems or concerns.
281 Each version is given a distinguishing version number. If the
282 Program specifies a version number of this License which applies
283 to it and "any later version", you have the option of following
284 the terms and conditions either of that version or of any later
285 version published by the Free Software Foundation. If the Program
286 does not specify a version number of this License, you may choose
287 any version ever published by the Free Software Foundation.
289 11. If you wish to incorporate parts of the Program into other free
290 programs whose distribution conditions are different, write to the
291 author to ask for permission. For software which is copyrighted
292 by the Free Software Foundation, write to the Free Software
293 Foundation; we sometimes make exceptions for this. Our decision
294 will be guided by the two goals of preserving the free status of
295 all derivatives of our free software and of promoting the sharing
296 and reuse of software generally.
300 12. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
301 WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
302 LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
303 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
304 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
305 NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
306 FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
307 QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
308 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
309 SERVICING, REPAIR OR CORRECTION.
311 13. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
312 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
313 MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
314 LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
315 INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
316 INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
317 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
318 OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
319 OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
320 ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
322 END OF TERMS AND CONDITIONS
324 How to Apply These Terms to Your New Programs
325 =============================================
327 If you develop a new program, and you want it to be of the greatest
328 possible use to the public, the best way to achieve this is to make it
329 free software which everyone can redistribute and change under these
332 To do so, attach the following notices to the program. It is safest
333 to attach them to the start of each source file to most effectively
334 convey the exclusion of warranty; and each file should have at least
335 the "copyright" line and a pointer to where the full notice is found.
337 ONE LINE TO GIVE THE PROGRAM'S NAME AND AN IDEA OF WHAT IT DOES.
