38 Everyone is permitted to copy and distribute verbatim copies
39 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
58 in 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, and
72 (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 GNU GENERAL PUBLIC LICENSE
92 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
94 0. This License applies to any program or other work which contains
95 a notice placed by the copyright holder saying it may be distributed
96 under the terms of this General Public License. The "Program", below,
97 refers to any such program or work, and a "work based on the Program"
98 means either the Program or any derivative work under copyright law:
99 that is to say, a work containing the Program or a portion of it,
100 either verbatim or with modifications and/or translated into another
101 language. (Hereinafter, translation is included without limitation in
102 the term "modification".) Each licensee is addressed as "you".
104 Activities other than copying, distribution and modification are not
105 covered by this License; they are outside its scope. The act of
106 running the Program is not restricted, and the output from the Program
107 is covered only if its contents constitute a work based on the
108 Program (independent of having been made by running the Program).
109 Whether that is true depends on what the Program does.
111 1. 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 warranty;
116 and give any other recipients of the Program a copy of this License
117 along with the Program.
119 You may charge a fee for the physical act of transferring a copy, and
120 you may at your option offer warranty protection in exchange for a fee.
122 2. You may modify your copy or copies of the Program or any portion
123 of it, thus forming a work based on the Program, and copy and
124 distribute such modifications or work under the terms of Section 1
125 above, provided that you also meet all of these conditions:
127 a) You must cause the modified files to carry prominent notices
128 stating that you changed the files and the date of any change.
130 b) You must cause any work that you distribute or publish, that in
131 whole or in part contains or is derived from the Program or any
132 part thereof, to be licensed as a whole at no charge to all third
133 parties under the terms of this License.
135 c) If the modified program normally reads commands interactively
136 when run, you must cause it, when started running for such
137 interactive use in the most ordinary way, to print or display an
138 announcement including an appropriate copyright notice and a
139 notice that there is no warranty (or else, saying that you provide
140 a warranty) and that users may redistribute the program under
141 these conditions, and telling the user how to view a copy of this
142 License. (Exception: if the Program itself is interactive but
143 does not normally print such an announcement, your work based on
144 the Program is not required to print an announcement.)
146 These requirements apply to the modified work as a whole. If
147 identifiable sections of that work are not derived from the Program,
148 and can be reasonably considered independent and separate works in
149 themselves, then this License, and its terms, do not apply to those
150 sections when you distribute them as separate works. But when you
151 distribute the same sections as part of a whole which is a work based
152 on the Program, the distribution of the whole must be on the terms of
153 this License, whose permissions for other licensees extend to the
154 entire whole, and thus to each and every part regardless of who wrote it.
156 Thus, it is not the intent of this section to claim rights or contest
157 your rights to work written entirely by you; rather, the intent is to
158 exercise the right to control the distribution of derivative or
159 collective works based on the Program.
161 In addition, mere aggregation of another work not based on the Program
162 with the Program (or with a work based on the Program) on a volume of
163 a storage or distribution medium does not bring the other work under
164 the scope of this License.
166 3. You may copy and distribute the Program (or a work based on it,
167 under Section 2) in object code or executable form under the terms of
168 Sections 1 and 2 above provided that you also do one of the following:
170 a) Accompany it with the complete corresponding machine-readable
171 source code, which must be distributed under the terms of Sections
172 1 and 2 above on a medium customarily used for software interchange; or,
174 b) Accompany it with a written offer, valid for at least three
175 years, to give any third party, for a charge no more than your
176 cost of physically performing source distribution, a complete
177 machine-readable copy of the corresponding source code, to be
178 distributed under the terms of Sections 1 and 2 above on a medium
179 customarily used for software interchange; or,
181 c) Accompany it with the information you received as to the offer
182 to distribute corresponding source code. (This alternative is
183 allowed only for noncommercial distribution and only if you
184 received the program in object code or executable form with such
185 an offer, in accord with Subsection b above.)
187 The source code for a work means the preferred form of the work for
188 making modifications to it. For an executable work, complete source
189 code means all the source code for all modules it contains, plus any
190 associated interface definition files, plus the scripts used to
191 control compilation and installation of the executable. However, as a
192 special exception, the source code distributed need not include
193 anything that is normally distributed (in either source or binary
194 form) with the major components (compiler, kernel, and so on) of the
195 operating system on which the executable runs, unless that component
196 itself accompanies the executable.
198 If distribution of executable or object code is made by offering
199 access to copy from a designated place, then offering equivalent
200 access to copy the source code from the same place counts as
201 distribution of the source code, even though third parties are not
202 compelled to copy the source along with the object code.
204 4. You may not copy, modify, sublicense, or distribute the Program
205 except as expressly provided under this License. Any attempt
206 otherwise to copy, modify, sublicense or distribute the Program is
207 void, and will automatically terminate your rights under this License.
208 However, parties who have received copies, or rights, from you under
209 this License will not have their licenses terminated so long as such
210 parties remain in full compliance.
212 5. You are not required to accept this License, since you have not
213 signed it. However, nothing else grants you permission to modify or
214 distribute the Program or its derivative works. These actions are
215 prohibited by law if you do not accept this License. Therefore, by
216 modifying or distributing the Program (or any work based on the
217 Program), you indicate your acceptance of this License to do so, and
218 all its terms and conditions for copying, distributing or modifying
219 the Program or works based on it.
221 6. Each time you redistribute the Program (or any work based on the
222 Program), the recipient automatically receives a license from the
223 original licensor to copy, distribute or modify the Program subject to
224 these terms and conditions. You may not impose any further
225 restrictions on the recipients' exercise of the rights granted herein.
226 You are not responsible for enforcing compliance by third parties to
229 7. If, as a consequence of a court judgment or allegation of patent
230 infringement or for any other reason (not limited to patent issues),
231 conditions are imposed on you (whether by court order, agreement or
232 otherwise) that contradict the conditions of this License, they do not
233 excuse you from the conditions of this License. If you cannot
234 distribute so as to satisfy simultaneously your obligations under this
235 License and any other pertinent obligations, then as a consequence you
236 may not distribute the Program at all. For example, if a patent
237 license would not permit royalty-free redistribution of the Program by
238 all those who receive copies directly or indirectly through you, then
239 the only way you could satisfy both it and this License would be to
240 refrain entirely from distribution of the Program.
242 If any portion of this section is held invalid or unenforceable under
243 any particular circumstance, the balance of the section is intended to
244 apply and the section as a whole is intended to apply in other
247 It is not the purpose of this section to induce you to infringe any
248 patents or other property right claims or to contest validity of any
249 such claims; this section has the sole purpose of protecting the
250 integrity of the free software distribution system, which is
251 implemented by public license practices. Many people have made
252 generous contributions to the wide range of software distributed
253 through that system in reliance on consistent application of that
254 system; it is up to the author/donor to decide if he or she is willing
255 to distribute software through any other system and a licensee cannot
258 This section is intended to make thoroughly clear what is believed to
259 be a consequence of the rest of this License.
261 8. If the distribution and/or use of the Program is restricted in
262 certain countries either by patents or by copyrighted interfaces, the
263 original copyright holder who places the Program under this License
264 may add an explicit geographical distribution limitation excluding
265 those countries, so that distribution is permitted only in or among
266 countries not thus excluded. In such case, this License incorporates
267 the limitation as if written in the body of this License.
269 9. The Free Software Foundation may publish revised and/or new versions
270 of the General Public License from time to time. Such new versions will
271 be similar in spirit to the present version, but may differ in detail to
272 address new problems or concerns.
274 Each version is given a distinguishing version number. If the Program
275 specifies a version number of this License which applies to it and "any
276 later version", you have the option of following the terms and conditions
277 either of that version or of any later version published by the Free
278 Software Foundation. If the Program does not specify a version number of
279 this License, you may choose any version ever published by the Free Software
282 10. If you wish to incorporate parts of the Program into other free
283 programs whose distribution conditions are different, write to the author
284 to ask for permission. For software which is copyrighted by the Free
285 Software Foundation, write to the Free Software Foundation; we sometimes
286 make exceptions for this. Our decision will be guided by the two goals
287 of preserving the free status of all derivatives of our free software and
288 of promoting the sharing and reuse of software generally.
292 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
293 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
294 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
295 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
296 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
297 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
298 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
299 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
300 REPAIR OR CORRECTION.
302 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
303 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
304 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
305 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
306 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
307 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
308 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
309 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
310 POSSIBILITY OF SUCH DAMAGES.
