54 GNU GENERAL PUBLIC LICENSE
57 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
58 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
59 Everyone is permitted to copy and distribute verbatim copies
60 of this license document, but changing it is not allowed.
64 The licenses for most software are designed to take away your
65 freedom to share and change it. By contrast, the GNU General Public
66 License is intended to guarantee your freedom to share and change free
67 software--to make sure the software is free for all its users. This
68 General Public License applies to most of the Free Software
69 Foundation's software and to any other program whose authors commit to
70 using it. (Some other Free Software Foundation software is covered by
71 the GNU Lesser General Public License instead.) You can apply it to
74 When we speak of free software, we are referring to freedom, not
75 price. Our General Public Licenses are designed to make sure that you
76 have the freedom to distribute copies of free software (and charge for
77 this service if you wish), that you receive source code or can get it
78 if you want it, that you can change the software or use pieces of it
79 in new free programs; and that you know you can do these things.
81 To protect your rights, we need to make restrictions that forbid
82 anyone to deny you these rights or to ask you to surrender the rights.
83 These restrictions translate to certain responsibilities for you if you
84 distribute copies of the software, or if you modify it.
86 For example, if you distribute copies of such a program, whether
87 gratis or for a fee, you must give the recipients all the rights that
88 you have. You must make sure that they, too, receive or can get the
89 source code. And you must show them these terms so they know their
92 We protect your rights with two steps: (1) copyright the software, and
93 (2) offer you this license which gives you legal permission to copy,
94 distribute and/or modify the software.
96 Also, for each author's protection and ours, we want to make certain
97 that everyone understands that there is no warranty for this free
98 software. If the software is modified by someone else and passed on, we
99 want its recipients to know that what they have is not the original, so
100 that any problems introduced by others will not reflect on the original
101 authors' reputations.
103 Finally, any free program is threatened constantly by software
104 patents. We wish to avoid the danger that redistributors of a free
105 program will individually obtain patent licenses, in effect making the
106 program proprietary. To prevent this, we have made it clear that any
107 patent must be licensed for everyone's free use or not licensed at all.
109 The precise terms and conditions for copying, distribution and
112 GNU GENERAL PUBLIC LICENSE
113 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
115 0. This License applies to any program or other work which contains
116 a notice placed by the copyright holder saying it may be distributed
117 under the terms of this General Public License. The "Program", below,
118 refers to any such program or work, and a "work based on the Program"
119 means either the Program or any derivative work under copyright law:
120 that is to say, a work containing the Program or a portion of it,
121 either verbatim or with modifications and/or translated into another
122 language. (Hereinafter, translation is included without limitation in
123 the term "modification".) Each licensee is addressed as "you".
125 Activities other than copying, distribution and modification are not
126 covered by this License; they are outside its scope. The act of
127 running the Program is not restricted, and the output from the Program
128 is covered only if its contents constitute a work based on the
129 Program (independent of having been made by running the Program).
130 Whether that is true depends on what the Program does.
132 1. You may copy and distribute verbatim copies of the Program's
133 source code as you receive it, in any medium, provided that you
134 conspicuously and appropriately publish on each copy an appropriate
135 copyright notice and disclaimer of warranty; keep intact all the
136 notices that refer to this License and to the absence of any warranty;
137 and give any other recipients of the Program a copy of this License
138 along with the Program.
140 You may charge a fee for the physical act of transferring a copy, and
141 you may at your option offer warranty protection in exchange for a fee.
143 2. You may modify your copy or copies of the Program or any portion
144 of it, thus forming a work based on the Program, and copy and
145 distribute such modifications or work under the terms of Section 1
146 above, provided that you also meet all of these conditions:
148 a) You must cause the modified files to carry prominent notices
149 stating that you changed the files and the date of any change.
151 b) You must cause any work that you distribute or publish, that in
152 whole or in part contains or is derived from the Program or any
153 part thereof, to be licensed as a whole at no charge to all third
154 parties under the terms of this License.
156 c) If the modified program normally reads commands interactively
157 when run, you must cause it, when started running for such
158 interactive use in the most ordinary way, to print or display an
159 announcement including an appropriate copyright notice and a
160 notice that there is no warranty (or else, saying that you provide
161 a warranty) and that users may redistribute the program under
162 these conditions, and telling the user how to view a copy of this
163 License. (Exception: if the Program itself is interactive but
164 does not normally print such an announcement, your work based on
165 the Program is not required to print an announcement.)
167 These requirements apply to the modified work as a whole. If
168 identifiable sections of that work are not derived from the Program,
169 and can be reasonably considered independent and separate works in
170 themselves, then this License, and its terms, do not apply to those
171 sections when you distribute them as separate works. But when you
172 distribute the same sections as part of a whole which is a work based
173 on the Program, the distribution of the whole must be on the terms of
174 this License, whose permissions for other licensees extend to the
175 entire whole, and thus to each and every part regardless of who wrote it.
177 Thus, it is not the intent of this section to claim rights or contest
178 your rights to work written entirely by you; rather, the intent is to
179 exercise the right to control the distribution of derivative or
180 collective works based on the Program.
182 In addition, mere aggregation of another work not based on the Program
183 with the Program (or with a work based on the Program) on a volume of
184 a storage or distribution medium does not bring the other work under
185 the scope of this License.
187 3. You may copy and distribute the Program (or a work based on it,
188 under Section 2) in object code or executable form under the terms of
189 Sections 1 and 2 above provided that you also do one of the following:
191 a) Accompany it with the complete corresponding machine-readable
192 source code, which must be distributed under the terms of Sections
193 1 and 2 above on a medium customarily used for software interchange; or,
195 b) Accompany it with a written offer, valid for at least three
196 years, to give any third party, for a charge no more than your
197 cost of physically performing source distribution, a complete
198 machine-readable copy of the corresponding source code, to be
199 distributed under the terms of Sections 1 and 2 above on a medium
200 customarily used for software interchange; or,
202 c) Accompany it with the information you received as to the offer
203 to distribute corresponding source code. (This alternative is
204 allowed only for noncommercial distribution and only if you
205 received the program in object code or executable form with such
206 an offer, in accord with Subsection b above.)
208 The source code for a work means the preferred form of the work for
209 making modifications to it. For an executable work, complete source
210 code means all the source code for all modules it contains, plus any
211 associated interface definition files, plus the scripts used to
212 control compilation and installation of the executable. However, as a
213 special exception, the source code distributed need not include
214 anything that is normally distributed (in either source or binary
215 form) with the major components (compiler, kernel, and so on) of the
216 operating system on which the executable runs, unless that component
217 itself accompanies the executable.
219 If distribution of executable or object code is made by offering
220 access to copy from a designated place, then offering equivalent
221 access to copy the source code from the same place counts as
222 distribution of the source code, even though third parties are not
223 compelled to copy the source along with the object code.
225 4. You may not copy, modify, sublicense, or distribute the Program
226 except as expressly provided under this License. Any attempt
227 otherwise to copy, modify, sublicense or distribute the Program is
228 void, and will automatically terminate your rights under this License.
229 However, parties who have received copies, or rights, from you under
230 this License will not have their licenses terminated so long as such
231 parties remain in full compliance.
233 5. You are not required to accept this License, since you have not
234 signed it. However, nothing else grants you permission to modify or
235 distribute the Program or its derivative works. These actions are
236 prohibited by law if you do not accept this License. Therefore, by
237 modifying or distributing the Program (or any work based on the
238 Program), you indicate your acceptance of this License to do so, and
239 all its terms and conditions for copying, distributing or modifying
240 the Program or works based on it.
242 6. Each time you redistribute the Program (or any work based on the
243 Program), the recipient automatically receives a license from the
244 original licensor to copy, distribute or modify the Program subject to
245 these terms and conditions. You may not impose any further
246 restrictions on the recipients' exercise of the rights granted herein.
247 You are not responsible for enforcing compliance by third parties to
250 7. If, as a consequence of a court judgment or allegation of patent
251 infringement or for any other reason (not limited to patent issues),
252 conditions are imposed on you (whether by court order, agreement or
253 otherwise) that contradict the conditions of this License, they do not
254 excuse you from the conditions of this License. If you cannot
255 distribute so as to satisfy simultaneously your obligations under this
256 License and any other pertinent obligations, then as a consequence you
257 may not distribute the Program at all. For example, if a patent
258 license would not permit royalty-free redistribution of the Program by
259 all those who receive copies directly or indirectly through you, then
260 the only way you could satisfy both it and this License would be to
261 refrain entirely from distribution of the Program.
263 If any portion of this section is held invalid or unenforceable under
264 any particular circumstance, the balance of the section is intended to
265 apply and the section as a whole is intended to apply in other
268 It is not the purpose of this section to induce you to infringe any
269 patents or other property right claims or to contest validity of any
270 such claims; this section has the sole purpose of protecting the
271 integrity of the free software distribution system, which is
272 implemented by public license practices. Many people have made
273 generous contributions to the wide range of software distributed
274 through that system in reliance on consistent application of that
275 system; it is up to the author/donor to decide if he or she is willing
276 to distribute software through any other system and a licensee cannot
279 This section is intended to make thoroughly clear what is believed to
280 be a consequence of the rest of this License.
282 8. If the distribution and/or use of the Program is restricted in
283 certain countries either by patents or by copyrighted interfaces, the
284 original copyright holder who places the Program under this License
285 may add an explicit geographical distribution limitation excluding
286 those countries, so that distribution is permitted only in or among
287 countries not thus excluded. In such case, this License incorporates
288 the limitation as if written in the body of this License.
290 9. The Free Software Foundation may publish revised and/or new versions
291 of the General Public License from time to time. Such new versions will
292 be similar in spirit to the present version, but may differ in detail to
293 address new problems or concerns.
295 Each version is given a distinguishing version number. If the Program
296 specifies a version number of this License which applies to it and "any
297 later version", you have the option of following the terms and conditions
298 either of that version or of any later version published by the Free
299 Software Foundation. If the Program does not specify a version number of
300 this License, you may choose any version ever published by the Free Software
303 10. If you wish to incorporate parts of the Program into other free
304 programs whose distribution conditions are different, write to the author
305 to ask for permission. For software which is copyrighted by the Free
306 Software Foundation, write to the Free Software Foundation; we sometimes
307 make exceptions for this. Our decision will be guided by the two goals
308 of preserving the free status of all derivatives of our free software and
309 of promoting the sharing and reuse of software generally.
313 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
314 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
315 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
316 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
317 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
318 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
319 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
320 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
321 REPAIR OR CORRECTION.
323 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
324 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
325 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
326 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
327 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
328 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
329 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
330 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
331 POSSIBILITY OF SUCH DAMAGES.
333 END OF TERMS AND CONDITIONS
335 How to Apply These Terms to Your New Programs
337 If you develop a new program, and you want it to be of the greatest
338 possible use to the public, the best way to achieve this is to make it
339 free software which everyone can redistribute and change under these terms.
341 To do so, attach the following notices to the program. It is safest
342 to attach them to the start of each source file to most effectively
343 convey the exclusion of warranty; and each file should have at least
344 the "copyright" line and a pointer to where the full notice is found.
346 <one line to give the program's name and a brief idea of what it does.>
347 Copyright (C) <year> <name of author>
349 This program is free software; you can redistribute it and/or modify
350 it under the terms of the GNU General Public License as published by
351 the Free Software Foundation; either version 2 of the License, or
352 (at your option) any later version.
354 This program is distributed in the hope that it will be useful,
355 but WITHOUT ANY WARRANTY; without even the implied warranty of
356 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
357 GNU General Public License for more details.
359 You should have received a copy of the GNU General Public License along
360 with this program; if not, write to the Free Software Foundation, Inc.,
361 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
363 Also add information on how to contact you by electronic and paper mail.
365 If the program is interactive, make it output a short notice like this
366 when it starts in an interactive mode:
368 Gnomovision version 69, Copyright (C) year name of author
369 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
370 This is free software, and you are welcome to redistribute it
371 under certain conditions; type `show c' for details.
373 The hypothetical commands `show w' and `show c' should show the appropriate
374 parts of the General Public License. Of course, the commands you use may
375 be called something other than `show w' and `show c'; they could even be
376 mouse-clicks or menu items--whatever suits your program.
378 You should also get your employer (if you work as a programmer) or your
379 school, if any, to sign a "copyright disclaimer" for the program, if
380 necessary. Here is a sample; alter the names:
382 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
383 `Gnomovision' (which makes passes at compilers) written by James Hacker.

388 This General Public License does not permit incorporating your program into
389 proprietary programs. If your program is a subroutine library, you may
390 consider it more useful to permit linking proprietary applications with the
391 library. If this is what you want to do, use the GNU Lesser General
392 Public License instead of this License.
399 <h2 class="SECT2"><a name="HISTORY" id="HISTORY">12.2. History</a></h2>
400 <p>A long time ago, there was the <span class="APPLICATION">Internet
401 Junkbuster</span>, by Anonymous Coders and Junkbusters Corporation.
402 This saved many users a lot of pain in the early days of web
403 advertising and user tracking.</p>
404 <p>But the web, its protocols and standards, and with it, the
405 techniques for forcing ads on users, give up autonomy over their
406 browsing, and for tracking them, keeps evolving. Unfortunately, the
407 <span class="APPLICATION">Internet Junkbuster</span> did not. Version
408 2.0.2, published in 1998, was the last official release, available from
409 Junkbusters Corporation. Fortunately, it had been released under the
410 GNU <a href="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
411 target="_top">GPL</a>, which allowed further development by others.</p>
412 <p>So Stefan Waldherr started maintaining an improved version of the
413 software, to which eventually a number of people contributed patches.
414 It could already replace banners with a transparent image, and had a
415 first version of pop-up killing, but it was still very closely based on
416 the original, with all its limitations, such as the lack of HTTP/1.1
417 support, flexible per-site configuration, or content modification. The
418 last release from this effort was version 2.0.2-10, published in
420 <p>Then, some <a href=
421 "https://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
422 "_top">developers</a> picked up the thread, and started turning the
423 software inside out, upside down, and then reassembled it, adding many
425 "https://www.privoxy.org/user-manual/introduction.html#FEATURES"
426 target="_top">new features</a> along the way.</p>
427 <p>The result of this is <span class="APPLICATION">Privoxy</span>,
428 whose first stable version, 3.0, was released August, 2002.</p>
429 <p>As of 2012 the Junkbusters Corporation's website
430 (http://www.junkbusters.com/) has been shut down, but Privoxy is still

589 <p>Privoxy is based in part on code originally developed by Junkbusters
590 Corp. and Anonymous Coders.</p>
591 <p>Privoxy heavily relies on Philip Hazel's PCRE.</p>
592 <p>The code to filter compressed content makes use of zlib which is
593 written by Jean-loup Gailly and Mark Adler.</p>
594 <p>On systems that lack snprintf(), Privoxy is using a version written
595 by Mark Martinec. On systems that lack strptime(), Privoxy is using the
596 one from the GNU C Library written by Ulrich Drepper.</p>
