20 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See either
21 the GNU General Public License or the Artistic License for more details.

32 For those of you that choose to use the GNU General Public License,
33 my interpretation of the GNU General Public License is that no Perl
34 script falls under the terms of the GPL unless you explicitly put
35 said script under the terms of the GPL yourself. Furthermore, any
36 object code linked with perl does not automatically fall under the
37 terms of the GPL, provided such object code only adds definitions
38 of subroutines and variables, and does not otherwise impair the
39 resulting interpreter from executing any standard Perl script. I
40 consider linking in C subroutines in this manner to be the moral
41 equivalent of defining subroutines in the Perl language itself. You
42 may sell such an object file as proprietary provided that you provide
43 or offer to provide the Perl source, as specified by the GNU General
44 Public License. (This is merely an alternate way of specifying input
45 to the program.) You may also sell a binary produced by the dumping of
46 a running Perl script that belongs to you, provided that you provide or
47 offer to provide the Perl source as specified by the GPL. (The
48 fact that a Perl interpreter and your code are in the same binary file
49 is, in this case, a form of mere aggregation.) This is my interpretation
50 of the GPL. If you still have concerns or difficulties understanding
51 my intent, feel free to contact me. Of course, the Artistic License
52 spells all this out for your protection, so you may prefer to use that.

57 GNU GENERAL PUBLIC LICENSE
58 Version 1, February 1989
60 Copyright (C) 1989 Free Software Foundation, Inc.
61 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
63 Everyone is permitted to copy and distribute verbatim copies
64 of this license document, but changing it is not allowed.
68 The license agreements of most software companies try to keep users
69 at the mercy of those companies. By contrast, our General Public
70 License is intended to guarantee your freedom to share and change free
71 software--to make sure the software is free for all its users. The
72 General Public License applies to the Free Software Foundation's
73 software and to any other program whose authors commit to using it.
74 You can use it for your programs, too.
76 When we speak of free software, we are referring to freedom, not
77 price. Specifically, the General Public License is designed to make
78 sure that you have the freedom to give away or sell copies of free
79 software, that you receive source code or can get it if you want it,
80 that you can change the software or use pieces of it in new free
81 programs; and that you know you can do these things.
83 To protect your rights, we need to make restrictions that forbid
84 anyone to deny you these rights or to ask you to surrender the rights.
85 These restrictions translate to certain responsibilities for you if you
86 distribute copies of the software, or if you modify it.
88 For example, if you distribute copies of a such a program, whether
89 gratis or for a fee, you must give the recipients all the rights that
90 you have. You must make sure that they, too, receive or can get the
91 source code. And you must tell them their rights.
93 We protect your rights with two steps: (1) copyright the software, and
94 (2) offer you this license which gives you legal permission to copy,
95 distribute and/or modify the software.
97 Also, for each author's protection and ours, we want to make certain
98 that everyone understands that there is no warranty for this free
99 software. If the software is modified by someone else and passed on, we
100 want its recipients to know that what they have is not the original, so
101 that any problems introduced by others will not reflect on the original
102 authors' reputations.
104 The precise terms and conditions for copying, distribution and
107 GNU GENERAL PUBLIC LICENSE
108 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
110 0. This License Agreement applies to any program or other work which
111 contains a notice placed by the copyright holder saying it may be
112 distributed under the terms of this General Public License. The
113 "Program", below, refers to any such program or work, and a "work based
114 on the Program" means either the Program or any work containing the
115 Program or a portion of it, either verbatim or with modifications. Each
116 licensee is addressed as "you".
118 1. You may copy and distribute verbatim copies of the Program's source
119 code as you receive it, in any medium, provided that you conspicuously and
120 appropriately publish on each copy an appropriate copyright notice and
121 disclaimer of warranty; keep intact all the notices that refer to this
122 General Public License and to the absence of any warranty; and give any
123 other recipients of the Program a copy of this General Public License
124 along with the Program. You may charge a fee for the physical act of
127 2. You may modify your copy or copies of the Program or any portion of
128 it, and copy and distribute such modifications under the terms of Paragraph
129 1 above, provided that you also do the following:
131 a) cause the modified files to carry prominent notices stating that
132 you changed the files and the date of any change; and
134 b) cause the whole of any work that you distribute or publish, that
135 in whole or in part contains the Program or any part thereof, either
136 with or without modifications, to be licensed at no charge to all
137 third parties under the terms of this General Public License (except
138 that you may choose to grant warranty protection to some or all
139 third parties, at your option).
141 c) If the modified program normally reads commands interactively when
142 run, you must cause it, when started running for such interactive use
143 in the simplest and most usual way, to print or display an
144 announcement including an appropriate copyright notice and a notice
145 that there is no warranty (or else, saying that you provide a
146 warranty) and that users may redistribute the program under these
147 conditions, and telling the user how to view a copy of this General
150 d) You may charge a fee for the physical act of transferring a
151 copy, and you may at your option offer warranty protection in
154 Mere aggregation of another independent work with the Program (or its
155 derivative) on a volume of a storage or distribution medium does not bring
156 the other work under the scope of these terms.
158 3. You may copy and distribute the Program (or a portion or derivative of
159 it, under Paragraph 2) in object code or executable form under the terms of
160 Paragraphs 1 and 2 above provided that you also do one of the following:
162 a) accompany it with the complete corresponding machine-readable
163 source code, which must be distributed under the terms of
164 Paragraphs 1 and 2 above; or,
166 b) accompany it with a written offer, valid for at least three
167 years, to give any third party free (except for a nominal charge
168 for the cost of distribution) a complete machine-readable copy of the
169 corresponding source code, to be distributed under the terms of
170 Paragraphs 1 and 2 above; or,
172 c) accompany it with the information you received as to where the
173 corresponding source code may be obtained. (This alternative is
174 allowed only for noncommercial distribution and only if you
175 received the program in object code or executable form alone.)
177 Source code for a work means the preferred form of the work for making
178 modifications to it. For an executable file, complete source code means
179 all the source code for all modules it contains; but, as a special
180 exception, it need not include source code for modules which are standard
181 libraries that accompany the operating system on which the executable
182 file runs, or for standard header files or definitions files that
183 accompany that operating system.
185 4. You may not copy, modify, sublicense, distribute or transfer the
186 Program except as expressly provided under this General Public License.
187 Any attempt otherwise to copy, modify, sublicense, distribute or transfer
188 the Program is void, and will automatically terminate your rights to use
189 the Program under this License. However, parties who have received
190 copies, or rights to use copies, from you under this General Public
191 License will not have their licenses terminated so long as such parties
192 remain in full compliance.
194 5. By copying, distributing or modifying the Program (or any work based
195 on the Program) you indicate your acceptance of this license to do so,
196 and all its terms and conditions.
198 6. Each time you redistribute the Program (or any work based on the
199 Program), the recipient automatically receives a license from the original
200 licensor to copy, distribute or modify the Program subject to these
201 terms and conditions. You may not impose any further restrictions on the
202 recipients' exercise of the rights granted herein.
204 7. The Free Software Foundation may publish revised and/or new versions
205 of the General Public License from time to time. Such new versions will
206 be similar in spirit to the present version, but may differ in detail to
207 address new problems or concerns.
209 Each version is given a distinguishing version number. If the Program
210 specifies a version number of the license which applies to it and "any
211 later version", you have the option of following the terms and conditions
212 either of that version or of any later version published by the Free
213 Software Foundation. If the Program does not specify a version number of
214 the license, you may choose any version ever published by the Free Software
217 8. If you wish to incorporate parts of the Program into other free
218 programs whose distribution conditions are different, write to the author
219 to ask for permission. For software which is copyrighted by the Free
220 Software Foundation, write to the Free Software Foundation; we sometimes
221 make exceptions for this. Our decision will be guided by the two goals
222 of preserving the free status of all derivatives of our free software and
223 of promoting the sharing and reuse of software generally.
227 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
228 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
229 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
230 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
231 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
232 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
233 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
234 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
235 REPAIR OR CORRECTION.
237 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
238 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
239 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
240 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
241 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
242 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
243 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
244 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
245 POSSIBILITY OF SUCH DAMAGES.
247 END OF TERMS AND CONDITIONS
249 Appendix: How to Apply These Terms to Your New Programs
251 If you develop a new program, and you want it to be of the greatest
252 possible use to humanity, the best way to achieve this is to make it
253 free software which everyone can redistribute and change under these
256 To do so, attach the following notices to the program. It is safest to
257 attach them to the start of each source file to most effectively convey
258 the exclusion of warranty; and each file should have at least the
259 "copyright" line and a pointer to where the full notice is found.
261 <one line to give the program's name and a brief idea of what it does.>
262 Copyright (C) 19yy <name of author>
264 This program is free software; you can redistribute it and/or modify
265 it under the terms of the GNU General Public License as published by
266 the Free Software Foundation; either version 1, or (at your option)
269 This program is distributed in the hope that it will be useful,
270 but WITHOUT ANY WARRANTY; without even the implied warranty of
271 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
272 GNU General Public License for more details.
274 You should have received a copy of the GNU General Public License
275 along with this program; if not, write to the Free Software
276 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA
279 Also add information on how to contact you by electronic and paper mail.
281 If the program is interactive, make it output a short notice like this
282 when it starts in an interactive mode:
284 Gnomovision version 69, Copyright (C) 19xx name of author
285 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
286 This is free software, and you are welcome to redistribute it
287 under certain conditions; type `show c' for details.
289 The hypothetical commands `show w' and `show c' should show the
290 appropriate parts of the General Public License. Of course, the
291 commands you use may be called something other than `show w' and `show
292 c'; they could even be mouse-clicks or menu items--whatever suits your
295 You should also get your employer (if you work as a programmer) or your
296 school, if any, to sign a "copyright disclaimer" for the program, if
297 necessary. Here a sample; alter the names:
299 Yoyodyne, Inc., hereby disclaims all copyright interest in the
300 program `Gnomovision' (a program to direct compilers to make passes
301 at assemblers) written by James Hacker.

309 --- Artistic --------------------------------------------------------------
311 The "Artistic License"
315 The intent of this document is to state the conditions under which a
316 Package may be copied, such that the Copyright Holder maintains some
317 semblance of artistic control over the development of the package,
318 while giving the users of the package the right to use and distribute
319 the Package in a more-or-less customary fashion, plus the right to make
320 reasonable modifications.
324 "Package" refers to the collection of files distributed by the
325 Copyright Holder, and derivatives of that collection of files
326 created through textual modification.
328 "Standard Version" refers to such a Package if it has not been
329 modified, or has been modified in accordance with the wishes
330 of the Copyright Holder as specified below.
332 "Copyright Holder" is whoever is named in the copyright or
333 copyrights for the package.
335 "You" is you, if you're thinking about copying or distributing
338 "Reasonable copying fee" is whatever you can justify on the
339 basis of media cost, duplication charges, time of people involved,
340 and so on. (You will not be required to justify it to the
341 Copyright Holder, but only to the computing community at large
342 as a market that must bear the fee.)
344 "Freely Available" means that no fee is charged for the item
345 itself, though there may be fees involved in handling the item.
346 It also means that recipients of the item may redistribute it
347 under the same conditions they received it.
349 1. You may make and give away verbatim copies of the source form of the
350 Standard Version of this Package without restriction, provided that you
351 duplicate all of the original copyright notices and associated disclaimers.
353 2. You may apply bug fixes, portability fixes and other modifications
354 derived from the Public Domain or from the Copyright Holder. A Package
355 modified in such a way shall still be considered the Standard Version.
357 3. You may otherwise modify your copy of this Package in any way, provided
358 that you insert a prominent notice in each changed file stating how and
359 when you changed that file, and provided that you do at least ONE of the
362 a) place your modifications in the Public Domain or otherwise make them
363 Freely Available, such as by posting said modifications to Usenet or
364 an equivalent medium, or placing the modifications on a major archive
365 site such as uunet.uu.net, or by allowing the Copyright Holder to include
366 your modifications in the Standard Version of the Package.
368 b) use the modified Package only within your corporation or organization.
370 c) rename any non-standard executables so the names do not conflict
371 with standard executables, which must also be provided, and provide
372 a separate manual page for each non-standard executable that clearly
373 documents how it differs from the Standard Version.
375 d) make other distribution arrangements with the Copyright Holder.
377 4. You may distribute the programs of this Package in object code or
378 executable form, provided that you do at least ONE of the following:
380 a) distribute a Standard Version of the executables and library files,
381 together with instructions (in the manual page or equivalent) on where
382 to get the Standard Version.
384 b) accompany the distribution with the machine-readable source of
385 the Package with your modifications.
387 c) give non-standard executables non-standard names, and clearly
388 document the differences in manual pages (or equivalent), together
389 with instructions on where to get the Standard Version.
391 d) make other distribution arrangements with the Copyright Holder.
393 5. You may charge a reasonable copying fee for any distribution of this
394 Package. You may charge any fee you choose for support of this
395 Package. You may not charge a fee for this Package itself. However,
396 you may distribute this Package in aggregate with other (possibly
397 commercial) programs as part of a larger (possibly commercial) software
398 distribution provided that you do not advertise this Package as a
399 product of your own. You may embed this Package's interpreter within
400 an executable of yours (by linking); this shall be construed as a mere
401 form of aggregation, provided that the complete Standard Version of the
402 interpreter is so embedded.
404 6. The scripts and library files supplied as input to or produced as
405 output from the programs of this Package do not automatically fall
406 under the copyright of this Package, but belong to whoever generated
407 them, and may be sold commercially, and may be aggregated with this
408 Package. If such scripts or library files are aggregated with this
409 Package via the so-called "undump" or "unexec" methods of producing a
410 binary executable image, then distribution of such an image shall
411 neither be construed as a distribution of this Package nor shall it
412 fall under the restrictions of Paragraphs 3 and 4, provided that you do
413 not represent such an executable image as a Standard Version of this
416 7. C subroutines (or comparably compiled subroutines in other
417 languages) supplied by you and linked into this Package in order to
418 emulate subroutines and variables of the language defined by this
419 Package shall not be considered part of this Package, but are the
420 equivalent of input as in Paragraph 6, provided these subroutines do
421 not change the language in any way that would cause it to fail the
422 regression tests for the language.
424 8. Aggregation of this Package with a commercial distribution is always
425 permitted provided that the use of this Package is embedded; that is,
426 when no overt attempt is made to make this Package's interfaces visible
427 to the end user of the commercial distribution. Such use shall not be
428 construed as a distribution of this Package.
430 9. The name of the Copyright Holder may not be used to endorse or promote
431 products derived from this software without specific prior written permission.
433 10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
434 IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
435 WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
