7 This software is free-as-in-speech software, and may be used, distributed,
8 and modified under the terms of either the GNU General Public Licence
9 version 2 or the Artistic Licence. It's up to you which one you use. The
10 full text of the licences can be found in the files GPL2.txt and
11 ARTISTIC.txt, respectively.
14 --- ARTISTIC.txt ----------------------------------------------------------
19 The "Artistic License"
23 The intent of this document is to state the conditions under which a
24 Package may be copied, such that the Copyright Holder maintains some
25 semblance of artistic control over the development of the package,
26 while giving the users of the package the right to use and distribute
27 the Package in a more-or-less customary fashion, plus the right to make
28 reasonable modifications.
32 "Package" refers to the collection of files distributed by the
33 Copyright Holder, and derivatives of that collection of files
34 created through textual modification.
36 "Standard Version" refers to such a Package if it has not been
37 modified, or has been modified in accordance with the wishes
38 of the Copyright Holder as specified below.
40 "Copyright Holder" is whoever is named in the copyright or
41 copyrights for the package.
43 "You" is you, if you're thinking about copying or distributing
46 "Reasonable copying fee" is whatever you can justify on the
47 basis of media cost, duplication charges, time of people involved,
48 and so on. (You will not be required to justify it to the
49 Copyright Holder, but only to the computing community at large
50 as a market that must bear the fee.)
52 "Freely Available" means that no fee is charged for the item
53 itself, though there may be fees involved in handling the item.
54 It also means that recipients of the item may redistribute it
55 under the same conditions they received it.
57 1. You may make and give away verbatim copies of the source form of the
58 Standard Version of this Package without restriction, provided that you
59 duplicate all of the original copyright notices and associated disclaimers.
61 2. You may apply bug fixes, portability fixes and other modifications
62 derived from the Public Domain or from the Copyright Holder. A Package
63 modified in such a way shall still be considered the Standard Version.
65 3. You may otherwise modify your copy of this Package in any way, provided
66 that you insert a prominent notice in each changed file stating how and
67 when you changed that file, and provided that you do at least ONE of the
70 a) place your modifications in the Public Domain or otherwise make them
71 Freely Available, such as by posting said modifications to Usenet or
72 an equivalent medium, or placing the modifications on a major archive
73 site such as uunet.uu.net, or by allowing the Copyright Holder to include
74 your modifications in the Standard Version of the Package.
76 b) use the modified Package only within your corporation or organization.
78 c) rename any non-standard executables so the names do not conflict
79 with standard executables, which must also be provided, and provide
80 a separate manual page for each non-standard executable that clearly
81 documents how it differs from the Standard Version.
83 d) make other distribution arrangements with the Copyright Holder.
85 4. You may distribute the programs of this Package in object code or
86 executable form, provided that you do at least ONE of the following:
88 a) distribute a Standard Version of the executables and library files,
89 together with instructions (in the manual page or equivalent) on where
90 to get the Standard Version.
92 b) accompany the distribution with the machine-readable source of
93 the Package with your modifications.
95 c) give non-standard executables non-standard names, and clearly
96 document the differences in manual pages (or equivalent), together
97 with instructions on where to get the Standard Version.
99 d) make other distribution arrangements with the Copyright Holder.
101 5. You may charge a reasonable copying fee for any distribution of this
102 Package. You may charge any fee you choose for support of this
103 Package. You may not charge a fee for this Package itself. However,
104 you may distribute this Package in aggregate with other (possibly
105 commercial) programs as part of a larger (possibly commercial) software
106 distribution provided that you do not advertise this Package as a
107 product of your own. You may embed this Package's interpreter within
108 an executable of yours (by linking); this shall be construed as a mere
109 form of aggregation, provided that the complete Standard Version of the
110 interpreter is so embedded.
112 6. The scripts and library files supplied as input to or produced as
113 output from the programs of this Package do not automatically fall
114 under the copyright of this Package, but belong to whoever generated
115 them, and may be sold commercially, and may be aggregated with this
116 Package. If such scripts or library files are aggregated with this
117 Package via the so-called "undump" or "unexec" methods of producing a
118 binary executable image, then distribution of such an image shall
119 neither be construed as a distribution of this Package nor shall it
120 fall under the restrictions of Paragraphs 3 and 4, provided that you do
121 not represent such an executable image as a Standard Version of this
124 7. C subroutines (or comparably compiled subroutines in other
125 languages) supplied by you and linked into this Package in order to
126 emulate subroutines and variables of the language defined by this
127 Package shall not be considered part of this Package, but are the
128 equivalent of input as in Paragraph 6, provided these subroutines do
129 not change the language in any way that would cause it to fail the
130 regression tests for the language.
132 8. Aggregation of this Package with a commercial distribution is always
133 permitted provided that the use of this Package is embedded; that is,
134 when no overt attempt is made to make this Package's interfaces visible
135 to the end user of the commercial distribution. Such use shall not be
136 construed as a distribution of this Package.
138 9. The name of the Copyright Holder may not be used to endorse or promote
139 products derived from this software without specific prior written permission.
141 10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
142 IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
143 WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

153 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
154 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
155 Everyone is permitted to copy and distribute verbatim copies
156 of this license document, but changing it is not allowed.
160 The licenses for most software are designed to take away your
161 freedom to share and change it. By contrast, the GNU General Public
162 License is intended to guarantee your freedom to share and change free
163 software--to make sure the software is free for all its users. This
164 General Public License applies to most of the Free Software
165 Foundation's software and to any other program whose authors commit to
166 using it. (Some other Free Software Foundation software is covered by
167 the GNU Lesser General Public License instead.) You can apply it to
170 When we speak of free software, we are referring to freedom, not
171 price. Our General Public Licenses are designed to make sure that you
172 have the freedom to distribute copies of free software (and charge for
173 this service if you wish), that you receive source code or can get it
174 if you want it, that you can change the software or use pieces of it
175 in new free programs; and that you know you can do these things.
177 To protect your rights, we need to make restrictions that forbid
178 anyone to deny you these rights or to ask you to surrender the rights.
179 These restrictions translate to certain responsibilities for you if you
180 distribute copies of the software, or if you modify it.
182 For example, if you distribute copies of such a program, whether
183 gratis or for a fee, you must give the recipients all the rights that
184 you have. You must make sure that they, too, receive or can get the
185 source code. And you must show them these terms so they know their
188 We protect your rights with two steps: (1) copyright the software, and
189 (2) offer you this license which gives you legal permission to copy,
190 distribute and/or modify the software.
192 Also, for each author's protection and ours, we want to make certain
193 that everyone understands that there is no warranty for this free
194 software. If the software is modified by someone else and passed on, we
195 want its recipients to know that what they have is not the original, so
196 that any problems introduced by others will not reflect on the original
197 authors' reputations.
199 Finally, any free program is threatened constantly by software
200 patents. We wish to avoid the danger that redistributors of a free
201 program will individually obtain patent licenses, in effect making the
202 program proprietary. To prevent this, we have made it clear that any
203 patent must be licensed for everyone's free use or not licensed at all.
205 The precise terms and conditions for copying, distribution and
208 GNU GENERAL PUBLIC LICENSE
209 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
211 0. This License applies to any program or other work which contains
212 a notice placed by the copyright holder saying it may be distributed
213 under the terms of this General Public License. The "Program", below,
214 refers to any such program or work, and a "work based on the Program"
215 means either the Program or any derivative work under copyright law:
216 that is to say, a work containing the Program or a portion of it,
217 either verbatim or with modifications and/or translated into another
218 language. (Hereinafter, translation is included without limitation in
219 the term "modification".) Each licensee is addressed as "you".
221 Activities other than copying, distribution and modification are not
222 covered by this License; they are outside its scope. The act of
223 running the Program is not restricted, and the output from the Program
224 is covered only if its contents constitute a work based on the
225 Program (independent of having been made by running the Program).
226 Whether that is true depends on what the Program does.
228 1. You may copy and distribute verbatim copies of the Program's
229 source code as you receive it, in any medium, provided that you
230 conspicuously and appropriately publish on each copy an appropriate
231 copyright notice and disclaimer of warranty; keep intact all the
232 notices that refer to this License and to the absence of any warranty;
233 and give any other recipients of the Program a copy of this License
234 along with the Program.
236 You may charge a fee for the physical act of transferring a copy, and
237 you may at your option offer warranty protection in exchange for a fee.
239 2. You may modify your copy or copies of the Program or any portion
240 of it, thus forming a work based on the Program, and copy and
241 distribute such modifications or work under the terms of Section 1
242 above, provided that you also meet all of these conditions:
244 a) You must cause the modified files to carry prominent notices
245 stating that you changed the files and the date of any change.
247 b) You must cause any work that you distribute or publish, that in
248 whole or in part contains or is derived from the Program or any
249 part thereof, to be licensed as a whole at no charge to all third
250 parties under the terms of this License.
252 c) If the modified program normally reads commands interactively
253 when run, you must cause it, when started running for such
254 interactive use in the most ordinary way, to print or display an
255 announcement including an appropriate copyright notice and a
256 notice that there is no warranty (or else, saying that you provide
257 a warranty) and that users may redistribute the program under
258 these conditions, and telling the user how to view a copy of this
259 License. (Exception: if the Program itself is interactive but
260 does not normally print such an announcement, your work based on
261 the Program is not required to print an announcement.)
263 These requirements apply to the modified work as a whole. If
264 identifiable sections of that work are not derived from the Program,
265 and can be reasonably considered independent and separate works in
266 themselves, then this License, and its terms, do not apply to those
267 sections when you distribute them as separate works. But when you
268 distribute the same sections as part of a whole which is a work based
269 on the Program, the distribution of the whole must be on the terms of
270 this License, whose permissions for other licensees extend to the
271 entire whole, and thus to each and every part regardless of who wrote it.
273 Thus, it is not the intent of this section to claim rights or contest
274 your rights to work written entirely by you; rather, the intent is to
275 exercise the right to control the distribution of derivative or
276 collective works based on the Program.
278 In addition, mere aggregation of another work not based on the Program
279 with the Program (or with a work based on the Program) on a volume of
280 a storage or distribution medium does not bring the other work under
281 the scope of this License.
283 3. You may copy and distribute the Program (or a work based on it,
284 under Section 2) in object code or executable form under the terms of
285 Sections 1 and 2 above provided that you also do one of the following:
287 a) Accompany it with the complete corresponding machine-readable
288 source code, which must be distributed under the terms of Sections
289 1 and 2 above on a medium customarily used for software interchange; or,
291 b) Accompany it with a written offer, valid for at least three
292 years, to give any third party, for a charge no more than your
293 cost of physically performing source distribution, a complete
294 machine-readable copy of the corresponding source code, to be
295 distributed under the terms of Sections 1 and 2 above on a medium
296 customarily used for software interchange; or,
298 c) Accompany it with the information you received as to the offer
299 to distribute corresponding source code. (This alternative is
300 allowed only for noncommercial distribution and only if you
301 received the program in object code or executable form with such
302 an offer, in accord with Subsection b above.)
304 The source code for a work means the preferred form of the work for
305 making modifications to it. For an executable work, complete source
306 code means all the source code for all modules it contains, plus any
307 associated interface definition files, plus the scripts used to
308 control compilation and installation of the executable. However, as a
309 special exception, the source code distributed need not include
310 anything that is normally distributed (in either source or binary
311 form) with the major components (compiler, kernel, and so on) of the
312 operating system on which the executable runs, unless that component
313 itself accompanies the executable.
315 If distribution of executable or object code is made by offering
316 access to copy from a designated place, then offering equivalent
317 access to copy the source code from the same place counts as
318 distribution of the source code, even though third parties are not
319 compelled to copy the source along with the object code.
321 4. You may not copy, modify, sublicense, or distribute the Program
322 except as expressly provided under this License. Any attempt
323 otherwise to copy, modify, sublicense or distribute the Program is
324 void, and will automatically terminate your rights under this License.
325 However, parties who have received copies, or rights, from you under
326 this License will not have their licenses terminated so long as such
327 parties remain in full compliance.
329 5. You are not required to accept this License, since you have not
330 signed it. However, nothing else grants you permission to modify or
331 distribute the Program or its derivative works. These actions are
332 prohibited by law if you do not accept this License. Therefore, by
333 modifying or distributing the Program (or any work based on the
334 Program), you indicate your acceptance of this License to do so, and
335 all its terms and conditions for copying, distributing or modifying
336 the Program or works based on it.
338 6. Each time you redistribute the Program (or any work based on the
339 Program), the recipient automatically receives a license from the
340 original licensor to copy, distribute or modify the Program subject to
341 these terms and conditions. You may not impose any further
342 restrictions on the recipients' exercise of the rights granted herein.
343 You are not responsible for enforcing compliance by third parties to
346 7. If, as a consequence of a court judgment or allegation of patent
347 infringement or for any other reason (not limited to patent issues),
348 conditions are imposed on you (whether by court order, agreement or
349 otherwise) that contradict the conditions of this License, they do not
350 excuse you from the conditions of this License. If you cannot
351 distribute so as to satisfy simultaneously your obligations under this
352 License and any other pertinent obligations, then as a consequence you
353 may not distribute the Program at all. For example, if a patent
354 license would not permit royalty-free redistribution of the Program by
355 all those who receive copies directly or indirectly through you, then
356 the only way you could satisfy both it and this License would be to
357 refrain entirely from distribution of the Program.
359 If any portion of this section is held invalid or unenforceable under
360 any particular circumstance, the balance of the section is intended to
361 apply and the section as a whole is intended to apply in other
364 It is not the purpose of this section to induce you to infringe any
365 patents or other property right claims or to contest validity of any
366 such claims; this section has the sole purpose of protecting the
367 integrity of the free software distribution system, which is
368 implemented by public license practices. Many people have made
369 generous contributions to the wide range of software distributed
370 through that system in reliance on consistent application of that
371 system; it is up to the author/donor to decide if he or she is willing
372 to distribute software through any other system and a licensee cannot
375 This section is intended to make thoroughly clear what is believed to
376 be a consequence of the rest of this License.
378 8. If the distribution and/or use of the Program is restricted in
379 certain countries either by patents or by copyrighted interfaces, the
380 original copyright holder who places the Program under this License
381 may add an explicit geographical distribution limitation excluding
382 those countries, so that distribution is permitted only in or among
383 countries not thus excluded. In such case, this License incorporates
384 the limitation as if written in the body of this License.
386 9. The Free Software Foundation may publish revised and/or new versions
387 of the General Public License from time to time. Such new versions will
388 be similar in spirit to the present version, but may differ in detail to
389 address new problems or concerns.
391 Each version is given a distinguishing version number. If the Program
392 specifies a version number of this License which applies to it and "any
393 later version", you have the option of following the terms and conditions
394 either of that version or of any later version published by the Free
395 Software Foundation. If the Program does not specify a version number of
396 this License, you may choose any version ever published by the Free Software
399 10. If you wish to incorporate parts of the Program into other free
400 programs whose distribution conditions are different, write to the author
401 to ask for permission. For software which is copyrighted by the Free
402 Software Foundation, write to the Free Software Foundation; we sometimes
403 make exceptions for this. Our decision will be guided by the two goals
404 of preserving the free status of all derivatives of our free software and
405 of promoting the sharing and reuse of software generally.
409 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
410 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
411 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
412 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
413 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
414 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
415 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
416 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
417 REPAIR OR CORRECTION.
419 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
420 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
421 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
422 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
423 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
424 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
425 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
426 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
427 POSSIBILITY OF SUCH DAMAGES.
429 END OF TERMS AND CONDITIONS
431 How to Apply These Terms to Your New Programs
433 If you develop a new program, and you want it to be of the greatest
434 possible use to the public, the best way to achieve this is to make it
435 free software which everyone can redistribute and change under these terms.
437 To do so, attach the following notices to the program. It is safest
438 to attach them to the start of each source file to most effectively
439 convey the exclusion of warranty; and each file should have at least
440 the "copyright" line and a pointer to where the full notice is found.
442 <one line to give the program's name and a brief idea of what it does.>
443 Copyright (C) <year> <name of author>
445 This program is free software; you can redistribute it and/or modify
446 it under the terms of the GNU General Public License as published by
447 the Free Software Foundation; either version 2 of the License, or
448 (at your option) any later version.
450 This program is distributed in the hope that it will be useful,
451 but WITHOUT ANY WARRANTY; without even the implied warranty of
452 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
453 GNU General Public License for more details.
455 You should have received a copy of the GNU General Public License along
456 with this program; if not, write to the Free Software Foundation, Inc.,
457 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
459 Also add information on how to contact you by electronic and paper mail.
461 If the program is interactive, make it output a short notice like this
462 when it starts in an interactive mode:
464 Gnomovision version 69, Copyright (C) year name of author
465 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
466 This is free software, and you are welcome to redistribute it
467 under certain conditions; type `show c' for details.
469 The hypothetical commands `show w' and `show c' should show the appropriate
470 parts of the General Public License. Of course, the commands you use may
471 be called something other than `show w' and `show c'; they could even be
472 mouse-clicks or menu items--whatever suits your program.
474 You should also get your employer (if you work as a programmer) or your
475 school, if any, to sign a "copyright disclaimer" for the program, if
476 necessary. Here is a sample; alter the names:
478 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
479 `Gnomovision' (which makes passes at compilers) written by James Hacker.

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