37 --- Artistic --------------------------------------------------------------
43 The "Artistic License"
47 The intent of this document is to state the conditions under which a
48 Package may be copied, such that the Copyright Holder maintains some
49 semblance of artistic control over the development of the package,
50 while giving the users of the package the right to use and distribute
51 the Package in a more-or-less customary fashion, plus the right to make
52 reasonable modifications.
56 "Package" refers to the collection of files distributed by the
57 Copyright Holder, and derivatives of that collection of files
58 created through textual modification.
60 "Standard Version" refers to such a Package if it has not been
61 modified, or has been modified in accordance with the wishes
62 of the Copyright Holder as specified below.
64 "Copyright Holder" is whoever is named in the copyright or
65 copyrights for the package.
67 "You" is you, if you're thinking about copying or distributing
70 "Reasonable copying fee" is whatever you can justify on the
71 basis of media cost, duplication charges, time of people involved,
72 and so on. (You will not be required to justify it to the
73 Copyright Holder, but only to the computing community at large
74 as a market that must bear the fee.)
76 "Freely Available" means that no fee is charged for the item
77 itself, though there may be fees involved in handling the item.
78 It also means that recipients of the item may redistribute it
79 under the same conditions they received it.
81 1. You may make and give away verbatim copies of the source form of the
82 Standard Version of this Package without restriction, provided that you
83 duplicate all of the original copyright notices and associated disclaimers.
85 2. You may apply bug fixes, portability fixes and other modifications
86 derived from the Public Domain or from the Copyright Holder. A Package
87 modified in such a way shall still be considered the Standard Version.
89 3. You may otherwise modify your copy of this Package in any way, provided
90 that you insert a prominent notice in each changed file stating how and
91 when you changed that file, and provided that you do at least ONE of the
94 a) place your modifications in the Public Domain or otherwise make them
95 Freely Available, such as by posting said modifications to Usenet or
96 an equivalent medium, or placing the modifications on a major archive
97 site such as uunet.uu.net, or by allowing the Copyright Holder to include
98 your modifications in the Standard Version of the Package.
100 b) use the modified Package only within your corporation or organization.
102 c) rename any non-standard executables so the names do not conflict
103 with standard executables, which must also be provided, and provide
104 a separate manual page for each non-standard executable that clearly
105 documents how it differs from the Standard Version.
107 d) make other distribution arrangements with the Copyright Holder.
109 4. You may distribute the programs of this Package in object code or
110 executable form, provided that you do at least ONE of the following:
112 a) distribute a Standard Version of the executables and library files,
113 together with instructions (in the manual page or equivalent) on where
114 to get the Standard Version.
116 b) accompany the distribution with the machine-readable source of
117 the Package with your modifications.
119 c) give non-standard executables non-standard names, and clearly
120 document the differences in manual pages (or equivalent), together
121 with instructions on where to get the Standard Version.
123 d) make other distribution arrangements with the Copyright Holder.
125 5. You may charge a reasonable copying fee for any distribution of this
126 Package. You may charge any fee you choose for support of this
127 Package. You may not charge a fee for this Package itself. However,
128 you may distribute this Package in aggregate with other (possibly
129 commercial) programs as part of a larger (possibly commercial) software
130 distribution provided that you do not advertise this Package as a
131 product of your own. You may embed this Package's interpreter within
132 an executable of yours (by linking); this shall be construed as a mere
133 form of aggregation, provided that the complete Standard Version of the
134 interpreter is so embedded.
136 6. The scripts and library files supplied as input to or produced as
137 output from the programs of this Package do not automatically fall
138 under the copyright of this Package, but belong to whoever generated
139 them, and may be sold commercially, and may be aggregated with this
140 Package. If such scripts or library files are aggregated with this
141 Package via the so-called "undump" or "unexec" methods of producing a
142 binary executable image, then distribution of such an image shall
143 neither be construed as a distribution of this Package nor shall it
144 fall under the restrictions of Paragraphs 3 and 4, provided that you do
145 not represent such an executable image as a Standard Version of this
148 7. C subroutines (or comparably compiled subroutines in other
149 languages) supplied by you and linked into this Package in order to
150 emulate subroutines and variables of the language defined by this
151 Package shall not be considered part of this Package, but are the
152 equivalent of input as in Paragraph 6, provided these subroutines do
153 not change the language in any way that would cause it to fail the
154 regression tests for the language.
156 8. Aggregation of this Package with a commercial distribution is always
157 permitted provided that the use of this Package is embedded; that is,
158 when no overt attempt is made to make this Package's interfaces visible
159 to the end user of the commercial distribution. Such use shall not be
160 construed as a distribution of this Package.
162 9. The name of the Copyright Holder may not be used to endorse or promote
163 products derived from this software without specific prior written permission.
165 10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
166 IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
167 WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

174 GNU GENERAL PUBLIC LICENSE
177 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
178 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
179 Everyone is permitted to copy and distribute verbatim copies
180 of this license document, but changing it is not allowed.
184 The licenses for most software are designed to take away your
185 freedom to share and change it. By contrast, the GNU General Public
186 License is intended to guarantee your freedom to share and change free
187 software--to make sure the software is free for all its users. This
188 General Public License applies to most of the Free Software
189 Foundation's software and to any other program whose authors commit to
190 using it. (Some other Free Software Foundation software is covered by
191 the GNU Lesser General Public License instead.) You can apply it to
194 When we speak of free software, we are referring to freedom, not
195 price. Our General Public Licenses are designed to make sure that you
196 have the freedom to distribute copies of free software (and charge for
197 this service if you wish), that you receive source code or can get it
198 if you want it, that you can change the software or use pieces of it
199 in new free programs; and that you know you can do these things.
201 To protect your rights, we need to make restrictions that forbid
202 anyone to deny you these rights or to ask you to surrender the rights.
203 These restrictions translate to certain responsibilities for you if you
204 distribute copies of the software, or if you modify it.
206 For example, if you distribute copies of such a program, whether
207 gratis or for a fee, you must give the recipients all the rights that
208 you have. You must make sure that they, too, receive or can get the
209 source code. And you must show them these terms so they know their
212 We protect your rights with two steps: (1) copyright the software, and
213 (2) offer you this license which gives you legal permission to copy,
214 distribute and/or modify the software.
216 Also, for each author's protection and ours, we want to make certain
217 that everyone understands that there is no warranty for this free
218 software. If the software is modified by someone else and passed on, we
219 want its recipients to know that what they have is not the original, so
220 that any problems introduced by others will not reflect on the original
221 authors' reputations.
223 Finally, any free program is threatened constantly by software
224 patents. We wish to avoid the danger that redistributors of a free
225 program will individually obtain patent licenses, in effect making the
226 program proprietary. To prevent this, we have made it clear that any
227 patent must be licensed for everyone's free use or not licensed at all.
229 The precise terms and conditions for copying, distribution and
232 GNU GENERAL PUBLIC LICENSE
233 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
235 0. This License applies to any program or other work which contains
236 a notice placed by the copyright holder saying it may be distributed
237 under the terms of this General Public License. The "Program", below,
238 refers to any such program or work, and a "work based on the Program"
239 means either the Program or any derivative work under copyright law:
240 that is to say, a work containing the Program or a portion of it,
241 either verbatim or with modifications and/or translated into another
242 language. (Hereinafter, translation is included without limitation in
243 the term "modification".) Each licensee is addressed as "you".
245 Activities other than copying, distribution and modification are not
246 covered by this License; they are outside its scope. The act of
247 running the Program is not restricted, and the output from the Program
248 is covered only if its contents constitute a work based on the
249 Program (independent of having been made by running the Program).
250 Whether that is true depends on what the Program does.
252 1. You may copy and distribute verbatim copies of the Program's
253 source code as you receive it, in any medium, provided that you
254 conspicuously and appropriately publish on each copy an appropriate
255 copyright notice and disclaimer of warranty; keep intact all the
256 notices that refer to this License and to the absence of any warranty;
257 and give any other recipients of the Program a copy of this License
258 along with the Program.
260 You may charge a fee for the physical act of transferring a copy, and
261 you may at your option offer warranty protection in exchange for a fee.
263 2. You may modify your copy or copies of the Program or any portion
264 of it, thus forming a work based on the Program, and copy and
265 distribute such modifications or work under the terms of Section 1
266 above, provided that you also meet all of these conditions:
268 a) You must cause the modified files to carry prominent notices
269 stating that you changed the files and the date of any change.
271 b) You must cause any work that you distribute or publish, that in
272 whole or in part contains or is derived from the Program or any
273 part thereof, to be licensed as a whole at no charge to all third
274 parties under the terms of this License.
276 c) If the modified program normally reads commands interactively
277 when run, you must cause it, when started running for such
278 interactive use in the most ordinary way, to print or display an
279 announcement including an appropriate copyright notice and a
280 notice that there is no warranty (or else, saying that you provide
281 a warranty) and that users may redistribute the program under
282 these conditions, and telling the user how to view a copy of this
283 License. (Exception: if the Program itself is interactive but
284 does not normally print such an announcement, your work based on
285 the Program is not required to print an announcement.)
287 These requirements apply to the modified work as a whole. If
288 identifiable sections of that work are not derived from the Program,
289 and can be reasonably considered independent and separate works in
290 themselves, then this License, and its terms, do not apply to those
291 sections when you distribute them as separate works. But when you
292 distribute the same sections as part of a whole which is a work based
293 on the Program, the distribution of the whole must be on the terms of
294 this License, whose permissions for other licensees extend to the
295 entire whole, and thus to each and every part regardless of who wrote it.
297 Thus, it is not the intent of this section to claim rights or contest
298 your rights to work written entirely by you; rather, the intent is to
299 exercise the right to control the distribution of derivative or
300 collective works based on the Program.
302 In addition, mere aggregation of another work not based on the Program
303 with the Program (or with a work based on the Program) on a volume of
304 a storage or distribution medium does not bring the other work under
305 the scope of this License.
307 3. You may copy and distribute the Program (or a work based on it,
308 under Section 2) in object code or executable form under the terms of
309 Sections 1 and 2 above provided that you also do one of the following:
311 a) Accompany it with the complete corresponding machine-readable
312 source code, which must be distributed under the terms of Sections
313 1 and 2 above on a medium customarily used for software interchange; or,
315 b) Accompany it with a written offer, valid for at least three
316 years, to give any third party, for a charge no more than your
317 cost of physically performing source distribution, a complete
318 machine-readable copy of the corresponding source code, to be
319 distributed under the terms of Sections 1 and 2 above on a medium
320 customarily used for software interchange; or,
322 c) Accompany it with the information you received as to the offer
323 to distribute corresponding source code. (This alternative is
324 allowed only for noncommercial distribution and only if you
325 received the program in object code or executable form with such
326 an offer, in accord with Subsection b above.)
328 The source code for a work means the preferred form of the work for
329 making modifications to it. For an executable work, complete source
330 code means all the source code for all modules it contains, plus any
331 associated interface definition files, plus the scripts used to
332 control compilation and installation of the executable. However, as a
333 special exception, the source code distributed need not include
334 anything that is normally distributed (in either source or binary
335 form) with the major components (compiler, kernel, and so on) of the
336 operating system on which the executable runs, unless that component
337 itself accompanies the executable.
339 If distribution of executable or object code is made by offering
340 access to copy from a designated place, then offering equivalent
341 access to copy the source code from the same place counts as
342 distribution of the source code, even though third parties are not
343 compelled to copy the source along with the object code.
345 4. You may not copy, modify, sublicense, or distribute the Program
346 except as expressly provided under this License. Any attempt
347 otherwise to copy, modify, sublicense or distribute the Program is
348 void, and will automatically terminate your rights under this License.
349 However, parties who have received copies, or rights, from you under
350 this License will not have their licenses terminated so long as such
351 parties remain in full compliance.
353 5. You are not required to accept this License, since you have not
354 signed it. However, nothing else grants you permission to modify or
355 distribute the Program or its derivative works. These actions are
356 prohibited by law if you do not accept this License. Therefore, by
357 modifying or distributing the Program (or any work based on the
358 Program), you indicate your acceptance of this License to do so, and
359 all its terms and conditions for copying, distributing or modifying
360 the Program or works based on it.
362 6. Each time you redistribute the Program (or any work based on the
363 Program), the recipient automatically receives a license from the
364 original licensor to copy, distribute or modify the Program subject to
365 these terms and conditions. You may not impose any further
366 restrictions on the recipients' exercise of the rights granted herein.
367 You are not responsible for enforcing compliance by third parties to
370 7. If, as a consequence of a court judgment or allegation of patent
371 infringement or for any other reason (not limited to patent issues),
372 conditions are imposed on you (whether by court order, agreement or
373 otherwise) that contradict the conditions of this License, they do not
374 excuse you from the conditions of this License. If you cannot
375 distribute so as to satisfy simultaneously your obligations under this
376 License and any other pertinent obligations, then as a consequence you
377 may not distribute the Program at all. For example, if a patent
378 license would not permit royalty-free redistribution of the Program by
379 all those who receive copies directly or indirectly through you, then
380 the only way you could satisfy both it and this License would be to
381 refrain entirely from distribution of the Program.
383 If any portion of this section is held invalid or unenforceable under
384 any particular circumstance, the balance of the section is intended to
385 apply and the section as a whole is intended to apply in other
388 It is not the purpose of this section to induce you to infringe any
389 patents or other property right claims or to contest validity of any
390 such claims; this section has the sole purpose of protecting the
391 integrity of the free software distribution system, which is
392 implemented by public license practices. Many people have made
393 generous contributions to the wide range of software distributed
394 through that system in reliance on consistent application of that
395 system; it is up to the author/donor to decide if he or she is willing
396 to distribute software through any other system and a licensee cannot
399 This section is intended to make thoroughly clear what is believed to
400 be a consequence of the rest of this License.
402 8. If the distribution and/or use of the Program is restricted in
403 certain countries either by patents or by copyrighted interfaces, the
404 original copyright holder who places the Program under this License
405 may add an explicit geographical distribution limitation excluding
406 those countries, so that distribution is permitted only in or among
407 countries not thus excluded. In such case, this License incorporates
408 the limitation as if written in the body of this License.
410 9. The Free Software Foundation may publish revised and/or new versions
411 of the General Public License from time to time. Such new versions will
412 be similar in spirit to the present version, but may differ in detail to
413 address new problems or concerns.
415 Each version is given a distinguishing version number. If the Program
416 specifies a version number of this License which applies to it and "any
417 later version", you have the option of following the terms and conditions
418 either of that version or of any later version published by the Free
419 Software Foundation. If the Program does not specify a version number of
420 this License, you may choose any version ever published by the Free Software
423 10. If you wish to incorporate parts of the Program into other free
424 programs whose distribution conditions are different, write to the author
425 to ask for permission. For software which is copyrighted by the Free
426 Software Foundation, write to the Free Software Foundation; we sometimes
427 make exceptions for this. Our decision will be guided by the two goals
428 of preserving the free status of all derivatives of our free software and
429 of promoting the sharing and reuse of software generally.
433 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
434 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
435 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
436 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
437 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
438 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
439 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
440 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
441 REPAIR OR CORRECTION.
443 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
444 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
445 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
446 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
447 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
448 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
449 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
450 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
451 POSSIBILITY OF SUCH DAMAGES.
453 END OF TERMS AND CONDITIONS
455 How to Apply These Terms to Your New Programs
457 If you develop a new program, and you want it to be of the greatest
458 possible use to the public, the best way to achieve this is to make it
459 free software which everyone can redistribute and change under these terms.
461 To do so, attach the following notices to the program. It is safest
462 to attach them to the start of each source file to most effectively
463 convey the exclusion of warranty; and each file should have at least
464 the "copyright" line and a pointer to where the full notice is found.
466 <one line to give the program's name and a brief idea of what it does.>
467 Copyright (C) <year> <name of author>
469 This program is free software; you can redistribute it and/or modify
470 it under the terms of the GNU General Public License as published by
471 the Free Software Foundation; either version 2 of the License, or
472 (at your option) any later version.
474 This program is distributed in the hope that it will be useful,
475 but WITHOUT ANY WARRANTY; without even the implied warranty of
476 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
477 GNU General Public License for more details.
479 You should have received a copy of the GNU General Public License along
480 with this program; if not, write to the Free Software Foundation, Inc.,
481 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
483 Also add information on how to contact you by electronic and paper mail.
485 If the program is interactive, make it output a short notice like this
486 when it starts in an interactive mode:
488 Gnomovision version 69, Copyright (C) year name of author
489 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type
\x13how w'.
490 This is free software, and you are welcome to redistribute it
491 under certain conditions; type
\x13how c' for details.
493 The hypothetical commands
\x13how w' and
\x13how c' should show the appropriate
494 parts of the General Public License. Of course, the commands you use may
495 be called something other than
\x13how w' and
\x13how c'; they could even be
496 mouse-clicks or menu items--whatever suits your program.
498 You should also get your employer (if you work as a programmer) or your
499 school, if any, to sign a "copyright disclaimer" for the program, if
500 necessary. Here is a sample; alter the names:
502 Yoyodyne, Inc., hereby disclaims all copyright interest in the program

508 This General Public License does not permit incorporating your program into
509 proprietary programs. If your program is a subroutine library, you may
510 consider it more useful to permit linking proprietary applications with the
511 library. If this is what you want to do, use the GNU Lesser General
512 Public License instead of this License.
