43 This program is free software; you can redistribute it and/or modify
44 it under the terms of either:
46 a. the GNU General Public License as published by the Free

50 b. the "Artistic License" which comes with this Kit.
52 This program is distributed in the hope that it will be useful,
53 but WITHOUT ANY WARRANTY; without even the implied warranty of
54 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See either
55 the GNU General Public License or the Artistic License for more details.
57 You should have received a copy of the Artistic License with this

66 For those of you that choose to use the GNU General Public License,
67 my interpretation of the GNU General Public License is that no Perl
68 script falls under the terms of the GPL unless you explicitly put
69 said script under the terms of the GPL yourself. Furthermore, any
70 object code linked with perl does not automatically fall under the
71 terms of the GPL, provided such object code only adds definitions
72 of subroutines and variables, and does not otherwise impair the
73 resulting interpreter from executing any standard Perl script. I
74 consider linking in C subroutines in this manner to be the moral
75 equivalent of defining subroutines in the Perl language itself. You
76 may sell such an object file as proprietary provided that you provide
77 or offer to provide the Perl source, as specified by the GNU General
78 Public License. (This is merely an alternate way of specifying input
79 to the program.) You may also sell a binary produced by the dumping of
80 a running Perl script that belongs to you, provided that you provide or
81 offer to provide the Perl source as specified by the GPL. (The
82 fact that a Perl interpreter and your code are in the same binary file
83 is, in this case, a form of mere aggregation.) This is my interpretation
84 of the GPL. If you still have concerns or difficulties understanding
85 my intent, feel free to contact me. Of course, the Artistic License
86 spells all this out for your protection, so you may prefer to use that.

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

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