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

49 GNU GENERAL PUBLIC LICENSE
50 Version 1, February 1989
52 Copyright (C) 1989 Free Software Foundation, Inc.
53 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
55 Everyone is permitted to copy and distribute verbatim copies
56 of this license document, but changing it is not allowed.
60 The license agreements of most software companies try to keep users
61 at the mercy of those companies. By contrast, our General Public
62 License is intended to guarantee your freedom to share and change free
63 software--to make sure the software is free for all its users. The
64 General Public License applies to the Free Software Foundation's
65 software and to any other program whose authors commit to using it.
66 You can use it for your programs, too.
68 When we speak of free software, we are referring to freedom, not
69 price. Specifically, the General Public License is designed to make
70 sure that you have the freedom to give away or sell copies of free
71 software, that you receive source code or can get it if you want it,
72 that you can change the software or use pieces of it in new free
73 programs; and that you know you can do these things.
75 To protect your rights, we need to make restrictions that forbid
76 anyone to deny you these rights or to ask you to surrender the rights.
77 These restrictions translate to certain responsibilities for you if you
78 distribute copies of the software, or if you modify it.
80 For example, if you distribute copies of a such a program, whether
81 gratis or for a fee, you must give the recipients all the rights that
82 you have. You must make sure that they, too, receive or can get the
83 source code. And you must tell them their rights.
85 We protect your rights with two steps: (1) copyright the software, and
86 (2) offer you this license which gives you legal permission to copy,
87 distribute and/or modify the software.
89 Also, for each author's protection and ours, we want to make certain
90 that everyone understands that there is no warranty for this free
91 software. If the software is modified by someone else and passed on, we
92 want its recipients to know that what they have is not the original, so
93 that any problems introduced by others will not reflect on the original
96 The precise terms and conditions for copying, distribution and
99 GNU GENERAL PUBLIC LICENSE
100 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
102 0. This License Agreement applies to any program or other work which
103 contains a notice placed by the copyright holder saying it may be
104 distributed under the terms of this General Public License. The
105 "Program", below, refers to any such program or work, and a "work based
106 on the Program" means either the Program or any work containing the
107 Program or a portion of it, either verbatim or with modifications. Each
108 licensee is addressed as "you".
110 1. You may copy and distribute verbatim copies of the Program's source
111 code as you receive it, in any medium, provided that you conspicuously and
112 appropriately publish on each copy an appropriate copyright notice and
113 disclaimer of warranty; keep intact all the notices that refer to this
114 General Public License and to the absence of any warranty; and give any
115 other recipients of the Program a copy of this General Public License
116 along with the Program. You may charge a fee for the physical act of
119 2. You may modify your copy or copies of the Program or any portion of
120 it, and copy and distribute such modifications under the terms of Paragraph
121 1 above, provided that you also do the following:
123 a) cause the modified files to carry prominent notices stating that
124 you changed the files and the date of any change; and
126 b) cause the whole of any work that you distribute or publish, that
127 in whole or in part contains the Program or any part thereof, either
128 with or without modifications, to be licensed at no charge to all
129 third parties under the terms of this General Public License (except
130 that you may choose to grant warranty protection to some or all
131 third parties, at your option).
133 c) If the modified program normally reads commands interactively when
134 run, you must cause it, when started running for such interactive use
135 in the simplest and most usual way, to print or display an
136 announcement including an appropriate copyright notice and a notice
137 that there is no warranty (or else, saying that you provide a
138 warranty) and that users may redistribute the program under these
139 conditions, and telling the user how to view a copy of this General
142 d) You may charge a fee for the physical act of transferring a
143 copy, and you may at your option offer warranty protection in
146 Mere aggregation of another independent work with the Program (or its
147 derivative) on a volume of a storage or distribution medium does not bring
148 the other work under the scope of these terms.
150 3. You may copy and distribute the Program (or a portion or derivative of
151 it, under Paragraph 2) in object code or executable form under the terms of
152 Paragraphs 1 and 2 above provided that you also do one of the following:
154 a) accompany it with the complete corresponding machine-readable
155 source code, which must be distributed under the terms of
156 Paragraphs 1 and 2 above; or,
158 b) accompany it with a written offer, valid for at least three
159 years, to give any third party free (except for a nominal charge
160 for the cost of distribution) a complete machine-readable copy of the
161 corresponding source code, to be distributed under the terms of
162 Paragraphs 1 and 2 above; or,
164 c) accompany it with the information you received as to where the
165 corresponding source code may be obtained. (This alternative is
166 allowed only for noncommercial distribution and only if you
167 received the program in object code or executable form alone.)
169 Source code for a work means the preferred form of the work for making
170 modifications to it. For an executable file, complete source code means
171 all the source code for all modules it contains; but, as a special
172 exception, it need not include source code for modules which are standard
173 libraries that accompany the operating system on which the executable
174 file runs, or for standard header files or definitions files that
175 accompany that operating system.
177 4. You may not copy, modify, sublicense, distribute or transfer the
178 Program except as expressly provided under this General Public License.
179 Any attempt otherwise to copy, modify, sublicense, distribute or transfer
180 the Program is void, and will automatically terminate your rights to use
181 the Program under this License. However, parties who have received
182 copies, or rights to use copies, from you under this General Public
183 License will not have their licenses terminated so long as such parties
184 remain in full compliance.
186 5. By copying, distributing or modifying the Program (or any work based
187 on the Program) you indicate your acceptance of this license to do so,
188 and all its terms and conditions.
190 6. Each time you redistribute the Program (or any work based on the
191 Program), the recipient automatically receives a license from the original
192 licensor to copy, distribute or modify the Program subject to these
193 terms and conditions. You may not impose any further restrictions on the
194 recipients' exercise of the rights granted herein.
196 7. The Free Software Foundation may publish revised and/or new versions
197 of the General Public License from time to time. Such new versions will
198 be similar in spirit to the present version, but may differ in detail to
199 address new problems or concerns.
201 Each version is given a distinguishing version number. If the Program
202 specifies a version number of the license which applies to it and "any
203 later version", you have the option of following the terms and conditions
204 either of that version or of any later version published by the Free
205 Software Foundation. If the Program does not specify a version number of
206 the license, you may choose any version ever published by the Free Software
209 8. If you wish to incorporate parts of the Program into other free
210 programs whose distribution conditions are different, write to the author
211 to ask for permission. For software which is copyrighted by the Free
212 Software Foundation, write to the Free Software Foundation; we sometimes
213 make exceptions for this. Our decision will be guided by the two goals
214 of preserving the free status of all derivatives of our free software and
215 of promoting the sharing and reuse of software generally.
219 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
220 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
221 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
222 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
223 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
224 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
225 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
226 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
227 REPAIR OR CORRECTION.
229 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
230 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
231 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
232 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
233 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
234 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
235 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
236 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
237 POSSIBILITY OF SUCH DAMAGES.
239 END OF TERMS AND CONDITIONS
241 Appendix: How to Apply These Terms to Your New Programs
243 If you develop a new program, and you want it to be of the greatest
244 possible use to humanity, the best way to achieve this is to make it
245 free software which everyone can redistribute and change under these
248 To do so, attach the following notices to the program. It is safest to
249 attach them to the start of each source file to most effectively convey
250 the exclusion of warranty; and each file should have at least the
251 "copyright" line and a pointer to where the full notice is found.
253 <one line to give the program's name and a brief idea of what it does.>
254 Copyright (C) 19yy <name of author>
256 This program is free software; you can redistribute it and/or modify
257 it under the terms of the GNU General Public License as published by
258 the Free Software Foundation; either version 1, or (at your option)
261 This program is distributed in the hope that it will be useful,
262 but WITHOUT ANY WARRANTY; without even the implied warranty of
263 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
264 GNU General Public License for more details.
266 You should have received a copy of the GNU General Public License
267 along with this program; if not, write to the Free Software
268 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA
271 Also add information on how to contact you by electronic and paper mail.
273 If the program is interactive, make it output a short notice like this
274 when it starts in an interactive mode:
276 Gnomovision version 69, Copyright (C) 19xx name of author
277 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
278 This is free software, and you are welcome to redistribute it
279 under certain conditions; type `show c' for details.
281 The hypothetical commands `show w' and `show c' should show the
282 appropriate parts of the General Public License. Of course, the
283 commands you use may be called something other than `show w' and `show
284 c'; they could even be mouse-clicks or menu items--whatever suits your
287 You should also get your employer (if you work as a programmer) or your
288 school, if any, to sign a "copyright disclaimer" for the program, if
289 necessary. Here a sample; alter the names:
291 Yoyodyne, Inc., hereby disclaims all copyright interest in the
292 program `Gnomovision' (a program to direct compilers to make passes
293 at assemblers) written by James Hacker.

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