147 \& Everyone is permitted to copy and distribute verbatim copies
148 \& of this license document, but changing it is not allowed.
151 .IX Subsection "Preamble"
153 \& The licenses for most software are designed to take away your
154 \&freedom to share and change it. By contrast, the GNU General Public
155 \&License is intended to guarantee your freedom to share and change free
156 \&software---to make sure the software is free for all its users. This
157 \&General Public License applies to most of the Free Software
158 \&Foundation's software and to any other program whose authors commit to
159 \&using it. (Some other Free Software Foundation software is covered by
160 \&the GNU Library General Public License instead.) You can apply it to
161 \&your programs, too.
165 \& When we speak of free software, we are referring to freedom, not
166 \&price. Our General Public Licenses are designed to make sure that you
167 \&have the freedom to distribute copies of free software (and charge for
168 \&this service if you wish), that you receive source code or can get it
169 \&if you want it, that you can change the software or use pieces of it
170 \&in new free programs; and that you know you can do these things.
174 \& To protect your rights, we need to make restrictions that forbid
175 \&anyone to deny you these rights or to ask you to surrender the rights.
176 \&These restrictions translate to certain responsibilities for you if you
177 \&distribute copies of the software, or if you modify it.
181 \& For example, if you distribute copies of such a program, whether
182 \&gratis or for a fee, you must give the recipients all the rights that
183 \&you have. You must make sure that they, too, receive or can get the
184 \&source code. And you must show them these terms so they know their
189 \& We protect your rights with two steps: (1) copyright the software, and
190 \&(2) offer you this license which gives you legal permission to copy,
191 \&distribute and/or modify the software.
195 \& Also, for each author's protection and ours, we want to make certain
196 \&that everyone understands that there is no warranty for this free
197 \&software. If the software is modified by someone else and passed on, we
198 \&want its recipients to know that what they have is not the original, so
199 \&that any problems introduced by others will not reflect on the original
200 \&authors' reputations.
204 \& Finally, any free program is threatened constantly by software
205 \&patents. We wish to avoid the danger that redistributors of a free
206 \&program will individually obtain patent licenses, in effect making the
207 \&program proprietary. To prevent this, we have made it clear that any
208 \&patent must be licensed for everyone's free use or not licensed at all.
212 \& The precise terms and conditions for copying, distribution and
213 \&modification follow.
215 .Sh "\s-1TERMS\s0 \s-1AND\s0 \s-1CONDITIONS\s0 \s-1FOR\s0 \s-1COPYING\s0, \s-1DISTRIBUTION\s0 \s-1AND\s0 \s-1MODIFICATION\s0"
216 .IX Subsection "TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION"
218 This License applies to any program or other work which contains
219 a notice placed by the copyright holder saying it may be distributed
220 under the terms of this General Public License. The ``Program'', below,
221 refers to any such program or work, and a ``work based on the Program''
222 means either the Program or any derivative work under copyright law:
223 that is to say, a work containing the Program or a portion of it,
224 either verbatim or with modifications and/or translated into another
225 language. (Hereinafter, translation is included without limitation in
226 the term ``modification''.) Each licensee is addressed as ``you''.
228 Activities other than copying, distribution and modification are not
229 covered by this License; they are outside its scope. The act of
230 running the Program is not restricted, and the output from the Program
231 is covered only if its contents constitute a work based on the
232 Program (independent of having been made by running the Program).
233 Whether that is true depends on what the Program does.
235 You may copy and distribute verbatim copies of the Program's
236 source code as you receive it, in any medium, provided that you
237 conspicuously and appropriately publish on each copy an appropriate
238 copyright notice and disclaimer of warranty; keep intact all the
239 notices that refer to this License and to the absence of any warranty;
240 and give any other recipients of the Program a copy of this License
241 along with the Program.
243 You may charge a fee for the physical act of transferring a copy, and
244 you may at your option offer warranty protection in exchange for a fee.
246 You may modify your copy or copies of the Program or any portion
247 of it, thus forming a work based on the Program, and copy and
248 distribute such modifications or work under the terms of Section 1
249 above, provided that you also meet all of these conditions:
252 You must cause the modified files to carry prominent notices
253 stating that you changed the files and the date of any change.
255 You must cause any work that you distribute or publish, that in
256 whole or in part contains or is derived from the Program or any
257 part thereof, to be licensed as a whole at no charge to all third
258 parties under the terms of this License.
260 If the modified program normally reads commands interactively
261 when run, you must cause it, when started running for such
262 interactive use in the most ordinary way, to print or display an
263 announcement including an appropriate copyright notice and a
264 notice that there is no warranty (or else, saying that you provide
265 a warranty) and that users may redistribute the program under
266 these conditions, and telling the user how to view a copy of this
267 License. (Exception: if the Program itself is interactive but
268 does not normally print such an announcement, your work based on
269 the Program is not required to print an announcement.)
273 These requirements apply to the modified work as a whole. If
274 identifiable sections of that work are not derived from the Program,
275 and can be reasonably considered independent and separate works in
276 themselves, then this License, and its terms, do not apply to those
277 sections when you distribute them as separate works. But when you
278 distribute the same sections as part of a whole which is a work based
279 on the Program, the distribution of the whole must be on the terms of
280 this License, whose permissions for other licensees extend to the
281 entire whole, and thus to each and every part regardless of who wrote it.
283 Thus, it is not the intent of this section to claim rights or contest
284 your rights to work written entirely by you; rather, the intent is to
285 exercise the right to control the distribution of derivative or
286 collective works based on the Program.
288 In addition, mere aggregation of another work not based on the Program
289 with the Program (or with a work based on the Program) on a volume of
290 a storage or distribution medium does not bring the other work under
291 the scope of this License.
294 You may copy and distribute the Program (or a work based on it,
295 under Section 2) in object code or executable form under the terms of
296 Sections 1 and 2 above provided that you also do one of the following:
299 Accompany it with the complete corresponding machine-readable
300 source code, which must be distributed under the terms of Sections
301 1 and 2 above on a medium customarily used for software interchange; or,
303 Accompany it with a written offer, valid for at least three
304 years, to give any third party, for a charge no more than your
305 cost of physically performing source distribution, a complete
306 machine-readable copy of the corresponding source code, to be
307 distributed under the terms of Sections 1 and 2 above on a medium
308 customarily used for software interchange; or,
310 Accompany it with the information you received as to the offer
311 to distribute corresponding source code. (This alternative is
312 allowed only for noncommercial distribution and only if you
313 received the program in object code or executable form with such
314 an offer, in accord with Subsection b above.)
318 The source code for a work means the preferred form of the work for
319 making modifications to it. For an executable work, complete source
320 code means all the source code for all modules it contains, plus any
321 associated interface definition files, plus the scripts used to
322 control compilation and installation of the executable. However, as a
323 special exception, the source code distributed need not include
324 anything that is normally distributed (in either source or binary
325 form) with the major components (compiler, kernel, and so on) of the
326 operating system on which the executable runs, unless that component
327 itself accompanies the executable.
329 If distribution of executable or object code is made by offering
330 access to copy from a designated place, then offering equivalent
331 access to copy the source code from the same place counts as
332 distribution of the source code, even though third parties are not
333 compelled to copy the source along with the object code.
336 You may not copy, modify, sublicense, or distribute the Program
337 except as expressly provided under this License. Any attempt
338 otherwise to copy, modify, sublicense or distribute the Program is
339 void, and will automatically terminate your rights under this License.
340 However, parties who have received copies, or rights, from you under
341 this License will not have their licenses terminated so long as such
342 parties remain in full compliance.
344 You are not required to accept this License, since you have not
345 signed it. However, nothing else grants you permission to modify or
346 distribute the Program or its derivative works. These actions are
347 prohibited by law if you do not accept this License. Therefore, by
348 modifying or distributing the Program (or any work based on the
349 Program), you indicate your acceptance of this License to do so, and
350 all its terms and conditions for copying, distributing or modifying
351 the Program or works based on it.
353 Each time you redistribute the Program (or any work based on the
354 Program), the recipient automatically receives a license from the
355 original licensor to copy, distribute or modify the Program subject to
356 these terms and conditions. You may not impose any further
357 restrictions on the recipients' exercise of the rights granted herein.
358 You are not responsible for enforcing compliance by third parties to
361 If, as a consequence of a court judgment or allegation of patent
362 infringement or for any other reason (not limited to patent issues),
363 conditions are imposed on you (whether by court order, agreement or
364 otherwise) that contradict the conditions of this License, they do not
365 excuse you from the conditions of this License. If you cannot
366 distribute so as to satisfy simultaneously your obligations under this
367 License and any other pertinent obligations, then as a consequence you
368 may not distribute the Program at all. For example, if a patent
369 license would not permit royalty-free redistribution of the Program by
370 all those who receive copies directly or indirectly through you, then
371 the only way you could satisfy both it and this License would be to
372 refrain entirely from distribution of the Program.
374 If any portion of this section is held invalid or unenforceable under
375 any particular circumstance, the balance of the section is intended to
376 apply and the section as a whole is intended to apply in other
379 It is not the purpose of this section to induce you to infringe any
380 patents or other property right claims or to contest validity of any
381 such claims; this section has the sole purpose of protecting the
382 integrity of the free software distribution system, which is
383 implemented by public license practices. Many people have made
384 generous contributions to the wide range of software distributed
385 through that system in reliance on consistent application of that
386 system; it is up to the author/donor to decide if he or she is willing
387 to distribute software through any other system and a licensee cannot
390 This section is intended to make thoroughly clear what is believed to
391 be a consequence of the rest of this License.
393 If the distribution and/or use of the Program is restricted in
394 certain countries either by patents or by copyrighted interfaces, the
395 original copyright holder who places the Program under this License
396 may add an explicit geographical distribution limitation excluding
397 those countries, so that distribution is permitted only in or among
398 countries not thus excluded. In such case, this License incorporates
399 the limitation as if written in the body of this License.
401 The Free Software Foundation may publish revised and/or new versions
402 of the General Public License from time to time. Such new versions will
403 be similar in spirit to the present version, but may differ in detail to
404 address new problems or concerns.
406 Each version is given a distinguishing version number. If the Program
407 specifies a version number of this License which applies to it and ``any
408 later version'', you have the option of following the terms and conditions
409 either of that version or of any later version published by the Free
410 Software Foundation. If the Program does not specify a version number of
411 this License, you may choose any version ever published by the Free Software
415 If you wish to incorporate parts of the Program into other free
416 programs whose distribution conditions are different, write to the author
417 to ask for permission. For software which is copyrighted by the Free
418 Software Foundation, write to the Free Software Foundation; we sometimes
419 make exceptions for this. Our decision will be guided by the two goals
420 of preserving the free status of all derivatives of our free software and
421 of promoting the sharing and reuse of software generally.
