12 PLEASE NOTE: It is the current maintainers intention to keep the dual
13 licensing intact. Until this notice is removed, releases will continue to
14 be available under both the standard GPL and the less restrictive Artistic
17 Verbatim copies of both licenses are included below:
21 --- The Artistic License 1.0 ---
23 The "Artistic License"
27 The intent of this document is to state the conditions under which a
28 Package may be copied, such that the Copyright Holder maintains some
29 semblance of artistic control over the development of the package,
30 while giving the users of the package the right to use and distribute
31 the Package in a more-or-less customary fashion, plus the right to make
32 reasonable modifications.
36 "Package" refers to the collection of files distributed by the
37 Copyright Holder, and derivatives of that collection of files
38 created through textual modification.
40 "Standard Version" refers to such a Package if it has not been
41 modified, or has been modified in accordance with the wishes
42 of the Copyright Holder as specified below.
44 "Copyright Holder" is whoever is named in the copyright or
45 copyrights for the package.
47 "You" is you, if you're thinking about copying or distributing
50 "Reasonable copying fee" is whatever you can justify on the
51 basis of media cost, duplication charges, time of people involved,
52 and so on. (You will not be required to justify it to the
53 Copyright Holder, but only to the computing community at large
54 as a market that must bear the fee.)
56 "Freely Available" means that no fee is charged for the item
57 itself, though there may be fees involved in handling the item.
58 It also means that recipients of the item may redistribute it
59 under the same conditions they received it.
61 1. You may make and give away verbatim copies of the source form of the
62 Standard Version of this Package without restriction, provided that you
63 duplicate all of the original copyright notices and associated disclaimers.
65 2. You may apply bug fixes, portability fixes and other modifications
66 derived from the Public Domain or from the Copyright Holder. A Package
67 modified in such a way shall still be considered the Standard Version.
69 3. You may otherwise modify your copy of this Package in any way, provided
70 that you insert a prominent notice in each changed file stating how and
71 when you changed that file, and provided that you do at least ONE of the
74 a) place your modifications in the Public Domain or otherwise make them
75 Freely Available, such as by posting said modifications to Usenet or
76 an equivalent medium, or placing the modifications on a major archive
77 site such as uunet.uu.net, or by allowing the Copyright Holder to include
78 your modifications in the Standard Version of the Package.
80 b) use the modified Package only within your corporation or organization.
82 c) rename any non-standard executables so the names do not conflict
83 with standard executables, which must also be provided, and provide
84 a separate manual page for each non-standard executable that clearly
85 documents how it differs from the Standard Version.
87 d) make other distribution arrangements with the Copyright Holder.
89 4. You may distribute the programs of this Package in object code or
90 executable form, provided that you do at least ONE of the following:
92 a) distribute a Standard Version of the executables and library files,
93 together with instructions (in the manual page or equivalent) on where
94 to get the Standard Version.
96 b) accompany the distribution with the machine-readable source of
97 the Package with your modifications.
99 c) give non-standard executables non-standard names, and clearly
100 document the differences in manual pages (or equivalent), together
101 with instructions on where to get the Standard Version.
103 d) make other distribution arrangements with the Copyright Holder.
105 5. You may charge a reasonable copying fee for any distribution of this
106 Package. You may charge any fee you choose for support of this
107 Package. You may not charge a fee for this Package itself. However,
108 you may distribute this Package in aggregate with other (possibly
109 commercial) programs as part of a larger (possibly commercial) software
110 distribution provided that you do not advertise this Package as a
111 product of your own. You may embed this Package's interpreter within
112 an executable of yours (by linking); this shall be construed as a mere
113 form of aggregation, provided that the complete Standard Version of the
114 interpreter is so embedded.
116 6. The scripts and library files supplied as input to or produced as
117 output from the programs of this Package do not automatically fall
118 under the copyright of this Package, but belong to whoever generated
119 them, and may be sold commercially, and may be aggregated with this
120 Package. If such scripts or library files are aggregated with this
121 Package via the so-called "undump" or "unexec" methods of producing a
122 binary executable image, then distribution of such an image shall
123 neither be construed as a distribution of this Package nor shall it
124 fall under the restrictions of Paragraphs 3 and 4, provided that you do
125 not represent such an executable image as a Standard Version of this
128 7. C subroutines (or comparably compiled subroutines in other
129 languages) supplied by you and linked into this Package in order to
130 emulate subroutines and variables of the language defined by this
131 Package shall not be considered part of this Package, but are the
132 equivalent of input as in Paragraph 6, provided these subroutines do
133 not change the language in any way that would cause it to fail the
134 regression tests for the language.
136 8. Aggregation of this Package with a commercial distribution is always
137 permitted provided that the use of this Package is embedded; that is,
138 when no overt attempt is made to make this Package's interfaces visible
139 to the end user of the commercial distribution. Such use shall not be
140 construed as a distribution of this Package.
142 9. The name of the Copyright Holder may not be used to endorse or promote
143 products derived from this software without specific prior written permission.
145 10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
146 IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
147 WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

160 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
162 Everyone is permitted to copy and distribute verbatim copies
163 of this license document, but changing it is not allowed.
167 The license agreements of most software companies try to keep users
168 at the mercy of those companies. By contrast, our General Public
169 License is intended to guarantee your freedom to share and change free
170 software--to make sure the software is free for all its users. The
171 General Public License applies to the Free Software Foundation's
172 software and to any other program whose authors commit to using it.
173 You can use it for your programs, too.
175 When we speak of free software, we are referring to freedom, not
176 price. Specifically, the General Public License is designed to make
177 sure that you have the freedom to give away or sell copies of free
178 software, that you receive source code or can get it if you want it,
179 that you can change the software or use pieces of it in new free
180 programs; and that you know you can do these things.
182 To protect your rights, we need to make restrictions that forbid
183 anyone to deny you these rights or to ask you to surrender the rights.
184 These restrictions translate to certain responsibilities for you if you
185 distribute copies of the software, or if you modify it.
187 For example, if you distribute copies of a such a program, whether
188 gratis or for a fee, you must give the recipients all the rights that
189 you have. You must make sure that they, too, receive or can get the
190 source code. And you must tell them their rights.
192 We protect your rights with two steps: (1) copyright the software, and
193 (2) offer you this license which gives you legal permission to copy,
194 distribute and/or modify the software.
196 Also, for each author's protection and ours, we want to make certain
197 that everyone understands that there is no warranty for this free
198 software. If the software is modified by someone else and passed on, we
199 want its recipients to know that what they have is not the original, so
200 that any problems introduced by others will not reflect on the original
201 authors' reputations.
203 The precise terms and conditions for copying, distribution and
206 GNU GENERAL PUBLIC LICENSE
207 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
209 0. This License Agreement applies to any program or other work which
210 contains a notice placed by the copyright holder saying it may be
211 distributed under the terms of this General Public License. The
212 "Program", below, refers to any such program or work, and a "work based
213 on the Program" means either the Program or any work containing the
214 Program or a portion of it, either verbatim or with modifications. Each
215 licensee is addressed as "you".
217 1. You may copy and distribute verbatim copies of the Program's source
218 code as you receive it, in any medium, provided that you conspicuously and
219 appropriately publish on each copy an appropriate copyright notice and
220 disclaimer of warranty; keep intact all the notices that refer to this
221 General Public License and to the absence of any warranty; and give any
222 other recipients of the Program a copy of this General Public License
223 along with the Program. You may charge a fee for the physical act of
226 2. You may modify your copy or copies of the Program or any portion of
227 it, and copy and distribute such modifications under the terms of Paragraph
228 1 above, provided that you also do the following:
230 a) cause the modified files to carry prominent notices stating that
231 you changed the files and the date of any change; and
233 b) cause the whole of any work that you distribute or publish, that
234 in whole or in part contains the Program or any part thereof, either
235 with or without modifications, to be licensed at no charge to all
236 third parties under the terms of this General Public License (except
237 that you may choose to grant warranty protection to some or all
238 third parties, at your option).
240 c) If the modified program normally reads commands interactively when
241 run, you must cause it, when started running for such interactive use
242 in the simplest and most usual way, to print or display an
243 announcement including an appropriate copyright notice and a notice
244 that there is no warranty (or else, saying that you provide a
245 warranty) and that users may redistribute the program under these
246 conditions, and telling the user how to view a copy of this General
249 d) You may charge a fee for the physical act of transferring a
250 copy, and you may at your option offer warranty protection in
253 Mere aggregation of another independent work with the Program (or its
254 derivative) on a volume of a storage or distribution medium does not bring
255 the other work under the scope of these terms.
257 3. You may copy and distribute the Program (or a portion or derivative of
258 it, under Paragraph 2) in object code or executable form under the terms of
259 Paragraphs 1 and 2 above provided that you also do one of the following:
261 a) accompany it with the complete corresponding machine-readable
262 source code, which must be distributed under the terms of
263 Paragraphs 1 and 2 above; or,
265 b) accompany it with a written offer, valid for at least three
266 years, to give any third party free (except for a nominal charge
267 for the cost of distribution) a complete machine-readable copy of the
268 corresponding source code, to be distributed under the terms of
269 Paragraphs 1 and 2 above; or,
271 c) accompany it with the information you received as to where the
272 corresponding source code may be obtained. (This alternative is
273 allowed only for noncommercial distribution and only if you
274 received the program in object code or executable form alone.)
276 Source code for a work means the preferred form of the work for making
277 modifications to it. For an executable file, complete source code means
278 all the source code for all modules it contains; but, as a special
279 exception, it need not include source code for modules which are standard
280 libraries that accompany the operating system on which the executable
281 file runs, or for standard header files or definitions files that
282 accompany that operating system.
284 4. You may not copy, modify, sublicense, distribute or transfer the
285 Program except as expressly provided under this General Public License.
286 Any attempt otherwise to copy, modify, sublicense, distribute or transfer
287 the Program is void, and will automatically terminate your rights to use
288 the Program under this License. However, parties who have received
289 copies, or rights to use copies, from you under this General Public
290 License will not have their licenses terminated so long as such parties
291 remain in full compliance.
293 5. By copying, distributing or modifying the Program (or any work based
294 on the Program) you indicate your acceptance of this license to do so,
295 and all its terms and conditions.
297 6. Each time you redistribute the Program (or any work based on the
298 Program), the recipient automatically receives a license from the original
299 licensor to copy, distribute or modify the Program subject to these
300 terms and conditions. You may not impose any further restrictions on the
301 recipients' exercise of the rights granted herein.
303 7. The Free Software Foundation may publish revised and/or new versions
304 of the General Public License from time to time. Such new versions will
305 be similar in spirit to the present version, but may differ in detail to
306 address new problems or concerns.
308 Each version is given a distinguishing version number. If the Program
309 specifies a version number of the license which applies to it and "any
310 later version", you have the option of following the terms and conditions
311 either of that version or of any later version published by the Free
312 Software Foundation. If the Program does not specify a version number of
313 the license, you may choose any version ever published by the Free Software
316 8. If you wish to incorporate parts of the Program into other free
317 programs whose distribution conditions are different, write to the author
318 to ask for permission. For software which is copyrighted by the Free
319 Software Foundation, write to the Free Software Foundation; we sometimes
320 make exceptions for this. Our decision will be guided by the two goals
321 of preserving the free status of all derivatives of our free software and
322 of promoting the sharing and reuse of software generally.
326 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
327 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
328 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
329 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
330 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
331 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
332 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
333 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
334 REPAIR OR CORRECTION.
336 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
337 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
338 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
339 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
340 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
341 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
342 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
343 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
344 POSSIBILITY OF SUCH DAMAGES.
346 END OF TERMS AND CONDITIONS
348 Appendix: How to Apply These Terms to Your New Programs
350 If you develop a new program, and you want it to be of the greatest
351 possible use to humanity, the best way to achieve this is to make it
352 free software which everyone can redistribute and change under these
355 To do so, attach the following notices to the program. It is safest to
356 attach them to the start of each source file to most effectively convey
357 the exclusion of warranty; and each file should have at least the
358 "copyright" line and a pointer to where the full notice is found.
360 <one line to give the program's name and a brief idea of what it does.>
361 Copyright (C) 19yy <name of author>
363 This program is free software; you can redistribute it and/or modify
364 it under the terms of the GNU General Public License as published by
365 the Free Software Foundation; either version 1, or (at your option)
368 This program is distributed in the hope that it will be useful,
369 but WITHOUT ANY WARRANTY; without even the implied warranty of
370 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
371 GNU General Public License for more details.
373 You should have received a copy of the GNU General Public License
374 along with this program; if not, write to the Free Software
375 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA
378 Also add information on how to contact you by electronic and paper mail.
380 If the program is interactive, make it output a short notice like this
381 when it starts in an interactive mode:
383 Gnomovision version 69, Copyright (C) 19xx name of author
384 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
385 This is free software, and you are welcome to redistribute it
386 under certain conditions; type `show c' for details.
388 The hypothetical commands `show w' and `show c' should show the
389 appropriate parts of the General Public License. Of course, the
390 commands you use may be called something other than `show w' and `show
391 c'; they could even be mouse-clicks or menu items--whatever suits your
394 You should also get your employer (if you work as a programmer) or your
395 school, if any, to sign a "copyright disclaimer" for the program, if
396 necessary. Here a sample; alter the names:
398 Yoyodyne, Inc., hereby disclaims all copyright interest in the
399 program `Gnomovision' (a program to direct compilers to make passes
400 at assemblers) written by James Hacker.
