| 31 | For those of you that choose to use the GNU General Public License, | |
| 32 | my interpretation of the GNU General Public License is that no Perl | |
| 33 | script falls under the terms of the GPL unless you explicitly put | |
| 34 | said script under the terms of the GPL yourself. Furthermore, any | |
| 35 | object code linked with perl does not automatically fall under the | |
| 36 | terms of the GPL, provided such object code only adds definitions | |
| 37 | of subroutines and variables, and does not otherwise impair the | |
| 38 | resulting interpreter from executing any standard Perl script. I | |
| 39 | consider linking in C subroutines in this manner to be the moral | |
| 40 | equivalent of defining subroutines in the Perl language itself. You | |
| 41 | may sell such an object file as proprietary provided that you provide | |
| 42 | or offer to provide the Perl source, as specified by the GNU General | |
| 43 | Public License. (This is merely an alternate way of specifying input | |
| 44 | to the program.) You may also sell a binary produced by the dumping of | |
| 45 | a running Perl script that belongs to you, provided that you provide or | |
| 46 | offer to provide the Perl source as specified by the GPL. (The | |
| 47 | fact that a Perl interpreter and your code are in the same binary file | |
| 48 | is, in this case, a form of mere aggregation.) This is my interpretation | |
| 49 | of the GPL. If you still have concerns or difficulties understanding | |
| 50 | my intent, feel free to contact me. Of course, the Artistic License | |
| 51 | spells all this out for your protection, so you may prefer to use that. | |

| 56 | GNU GENERAL PUBLIC LICENSE | |
| 57 | Version 1, February 1989 | |
| 58 | ||
| 59 | Copyright (C) 1989 Free Software Foundation, Inc. | |
| 60 | 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA | |
| 61 | ||
| 62 | Everyone is permitted to copy and distribute verbatim copies | |
| 63 | of this license document, but changing it is not allowed. | |
| 64 | ||
| 65 | Preamble | |
| 66 | ||
| 67 | The license agreements of most software companies try to keep users | |
| 68 | at the mercy of those companies. By contrast, our General Public | |
| 69 | License is intended to guarantee your freedom to share and change free | |
| 70 | software--to make sure the software is free for all its users. The | |
| 71 | General Public License applies to the Free Software Foundation's | |
| 72 | software and to any other program whose authors commit to using it. | |
| 73 | You can use it for your programs, too. | |
| 74 | ||
| 75 | When we speak of free software, we are referring to freedom, not | |
| 76 | price. Specifically, the General Public License is designed to make | |
| 77 | sure that you have the freedom to give away or sell copies of free | |
| 78 | software, that you receive source code or can get it if you want it, | |
| 79 | that you can change the software or use pieces of it in new free | |
| 80 | programs; and that you know you can do these things. | |
| 81 | ||
| 82 | To protect your rights, we need to make restrictions that forbid | |
| 83 | anyone to deny you these rights or to ask you to surrender the rights. | |
| 84 | These restrictions translate to certain responsibilities for you if you | |
| 85 | distribute copies of the software, or if you modify it. | |
| 86 | ||
| 87 | For example, if you distribute copies of a such a program, whether | |
| 88 | gratis or for a fee, you must give the recipients all the rights that | |
| 89 | you have. You must make sure that they, too, receive or can get the | |
| 90 | source code. And you must tell them their rights. | |
| 91 | ||
| 92 | We protect your rights with two steps: (1) copyright the software, and | |
| 93 | (2) offer you this license which gives you legal permission to copy, | |
| 94 | distribute and/or modify the software. | |
| 95 | ||
| 96 | Also, for each author's protection and ours, we want to make certain | |
| 97 | that everyone understands that there is no warranty for this free | |
| 98 | software. If the software is modified by someone else and passed on, we | |
| 99 | want its recipients to know that what they have is not the original, so | |
| 100 | that any problems introduced by others will not reflect on the original | |
| 101 | authors' reputations. | |
| 102 | ||
| 103 | The precise terms and conditions for copying, distribution and | |
| 104 | modification follow. | |
| 105 | ||
| 106 | GNU GENERAL PUBLIC LICENSE | |
| 107 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION | |
| 108 | ||
| 109 | 0. This License Agreement applies to any program or other work which | |
| 110 | contains a notice placed by the copyright holder saying it may be | |
| 111 | distributed under the terms of this General Public License. The | |
| 112 | "Program", below, refers to any such program or work, and a "work based | |
| 113 | on the Program" means either the Program or any work containing the | |
| 114 | Program or a portion of it, either verbatim or with modifications. Each | |
| 115 | licensee is addressed as "you". | |
| 116 | ||
| 117 | 1. You may copy and distribute verbatim copies of the Program's source | |
| 118 | code as you receive it, in any medium, provided that you conspicuously and | |
| 119 | appropriately publish on each copy an appropriate copyright notice and | |
| 120 | disclaimer of warranty; keep intact all the notices that refer to this | |
| 121 | General Public License and to the absence of any warranty; and give any | |
| 122 | other recipients of the Program a copy of this General Public License | |
| 123 | along with the Program. You may charge a fee for the physical act of | |
| 124 | transferring a copy. | |
| 125 | ||
| 126 | 2. You may modify your copy or copies of the Program or any portion of | |
| 127 | it, and copy and distribute such modifications under the terms of Paragraph | |
| 128 | 1 above, provided that you also do the following: | |
| 129 | ||
| 130 | a) cause the modified files to carry prominent notices stating that | |
| 131 | you changed the files and the date of any change; and | |
| 132 | ||
| 133 | b) cause the whole of any work that you distribute or publish, that | |
| 134 | in whole or in part contains the Program or any part thereof, either | |
| 135 | with or without modifications, to be licensed at no charge to all | |
| 136 | third parties under the terms of this General Public License (except | |
| 137 | that you may choose to grant warranty protection to some or all | |
| 138 | third parties, at your option). | |
| 139 | ||
| 140 | c) If the modified program normally reads commands interactively when | |
| 141 | run, you must cause it, when started running for such interactive use | |
| 142 | in the simplest and most usual way, to print or display an | |
| 143 | announcement including an appropriate copyright notice and a notice | |
| 144 | that there is no warranty (or else, saying that you provide a | |
| 145 | warranty) and that users may redistribute the program under these | |
| 146 | conditions, and telling the user how to view a copy of this General | |
| 147 | Public License. | |
| 148 | ||
| 149 | d) You may charge a fee for the physical act of transferring a | |
| 150 | copy, and you may at your option offer warranty protection in | |
| 151 | exchange for a fee. | |
| 152 | ||
| 153 | Mere aggregation of another independent work with the Program (or its | |
| 154 | derivative) on a volume of a storage or distribution medium does not bring | |
| 155 | the other work under the scope of these terms. | |
| 156 | ||
| 157 | 3. You may copy and distribute the Program (or a portion or derivative of | |
| 158 | it, under Paragraph 2) in object code or executable form under the terms of | |
| 159 | Paragraphs 1 and 2 above provided that you also do one of the following: | |
| 160 | ||
| 161 | a) accompany it with the complete corresponding machine-readable | |
| 162 | source code, which must be distributed under the terms of | |
| 163 | Paragraphs 1 and 2 above; or, | |
| 164 | ||
| 165 | b) accompany it with a written offer, valid for at least three | |
| 166 | years, to give any third party free (except for a nominal charge | |
| 167 | for the cost of distribution) a complete machine-readable copy of the | |
| 168 | corresponding source code, to be distributed under the terms of | |
| 169 | Paragraphs 1 and 2 above; or, | |
| 170 | ||
| 171 | c) accompany it with the information you received as to where the | |
| 172 | corresponding source code may be obtained. (This alternative is | |
| 173 | allowed only for noncommercial distribution and only if you | |
| 174 | received the program in object code or executable form alone.) | |
| 175 | ||
| 176 | Source code for a work means the preferred form of the work for making | |
| 177 | modifications to it. For an executable file, complete source code means | |
| 178 | all the source code for all modules it contains; but, as a special | |
| 179 | exception, it need not include source code for modules which are standard | |
| 180 | libraries that accompany the operating system on which the executable | |
| 181 | file runs, or for standard header files or definitions files that | |
| 182 | accompany that operating system. | |
| 183 | ||
| 184 | 4. You may not copy, modify, sublicense, distribute or transfer the | |
| 185 | Program except as expressly provided under this General Public License. | |
| 186 | Any attempt otherwise to copy, modify, sublicense, distribute or transfer | |
| 187 | the Program is void, and will automatically terminate your rights to use | |
| 188 | the Program under this License. However, parties who have received | |
| 189 | copies, or rights to use copies, from you under this General Public | |
| 190 | License will not have their licenses terminated so long as such parties | |
| 191 | remain in full compliance. | |
| 192 | ||
| 193 | 5. By copying, distributing or modifying the Program (or any work based | |
| 194 | on the Program) you indicate your acceptance of this license to do so, | |
| 195 | and all its terms and conditions. | |
| 196 | ||
| 197 | 6. Each time you redistribute the Program (or any work based on the | |
| 198 | Program), the recipient automatically receives a license from the original | |
| 199 | licensor to copy, distribute or modify the Program subject to these | |
| 200 | terms and conditions. You may not impose any further restrictions on the | |
| 201 | recipients' exercise of the rights granted herein. | |
| 202 | ||
| 203 | 7. The Free Software Foundation may publish revised and/or new versions | |
| 204 | of the General Public License from time to time. Such new versions will | |
| 205 | be similar in spirit to the present version, but may differ in detail to | |
| 206 | address new problems or concerns. | |
| 207 | ||
| 208 | Each version is given a distinguishing version number. If the Program | |
| 209 | specifies a version number of the license which applies to it and "any | |
| 210 | later version", you have the option of following the terms and conditions | |
| 211 | either of that version or of any later version published by the Free | |
| 212 | Software Foundation. If the Program does not specify a version number of | |
| 213 | the license, you may choose any version ever published by the Free Software | |
| 214 | Foundation. | |
| 215 | ||
| 216 | 8. If you wish to incorporate parts of the Program into other free | |
| 217 | programs whose distribution conditions are different, write to the author | |
| 218 | to ask for permission. For software which is copyrighted by the Free | |
| 219 | Software Foundation, write to the Free Software Foundation; we sometimes | |
| 220 | make exceptions for this. Our decision will be guided by the two goals | |
| 221 | of preserving the free status of all derivatives of our free software and | |
| 222 | of promoting the sharing and reuse of software generally. | |
| 223 | ||
| 224 | NO WARRANTY | |
| 225 | ||
| 226 | 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY | |
| 227 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN | |
| 228 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES | |
| 229 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED | |
| 230 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF | |
| 231 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS | |
| 232 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE | |
| 233 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, | |
| 234 | REPAIR OR CORRECTION. | |
| 235 | ||
| 236 | 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
| 237 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR | |
| 238 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, | |
| 239 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING | |
| 240 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED | |
| 241 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY | |
| 242 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER | |
| 243 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE | |
| 244 | POSSIBILITY OF SUCH DAMAGES. | |
| 245 | ||
| 246 | END OF TERMS AND CONDITIONS | |
| 247 | ||
| 248 | Appendix: How to Apply These Terms to Your New Programs | |
| 249 | ||
| 250 | If you develop a new program, and you want it to be of the greatest | |
| 251 | possible use to humanity, the best way to achieve this is to make it | |
| 252 | free software which everyone can redistribute and change under these | |
| 253 | terms. | |
| 254 | ||
| 255 | To do so, attach the following notices to the program. It is safest to | |
| 256 | attach them to the start of each source file to most effectively convey | |
| 257 | the exclusion of warranty; and each file should have at least the | |
| 258 | "copyright" line and a pointer to where the full notice is found. | |
| 259 | ||
| 260 | <one line to give the program's name and a brief idea of what it does.> | |
| 261 | Copyright (C) 19yy <name of author> | |
| 262 | ||
| 263 | This program is free software; you can redistribute it and/or modify | |
| 264 | it under the terms of the GNU General Public License as published by | |
| 265 | the Free Software Foundation; either version 1, or (at your option) | |
| 266 | any later version. | |
| 267 | ||
| 268 | This program is distributed in the hope that it will be useful, | |
| 269 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |
| 270 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | |
| 271 | GNU General Public License for more details. | |
| 272 | ||
| 273 | You should have received a copy of the GNU General Public License | |
| 274 | along with this program; if not, write to the Free Software | |
| 275 | Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA | |
| 276 | ||
| 277 | ||
| 278 | Also add information on how to contact you by electronic and paper mail. | |
| 279 | ||
| 280 | If the program is interactive, make it output a short notice like this | |
| 281 | when it starts in an interactive mode: | |
| 282 | ||
| 283 | Gnomovision version 69, Copyright (C) 19xx name of author | |
| 284 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. | |
| 285 | This is free software, and you are welcome to redistribute it | |
| 286 | under certain conditions; type `show c' for details. | |
| 287 | ||
| 288 | The hypothetical commands `show w' and `show c' should show the | |
| 289 | appropriate parts of the General Public License. Of course, the | |
| 290 | commands you use may be called something other than `show w' and `show | |
| 291 | c'; they could even be mouse-clicks or menu items--whatever suits your | |
| 292 | program. | |
| 293 | ||
| 294 | You should also get your employer (if you work as a programmer) or your | |
| 295 | school, if any, to sign a "copyright disclaimer" for the program, if | |
| 296 | necessary. Here a sample; alter the names: | |
| 297 | ||
| 298 | Yoyodyne, Inc., hereby disclaims all copyright interest in the | |
| 299 | program `Gnomovision' (a program to direct compilers to make passes | |
| 300 | at assemblers) written by James Hacker. | |

| 307 | ||
| 308 | --- Artistic -------------------------------------------------------------- | |
| 309 | ||
| 310 | The "Artistic License" | |
| 311 | ||
| 312 | Preamble | |
| 313 | ||
| 314 | The intent of this document is to state the conditions under which a | |
| 315 | Package may be copied, such that the Copyright Holder maintains some | |
| 316 | semblance of artistic control over the development of the package, | |
| 317 | while giving the users of the package the right to use and distribute | |
| 318 | the Package in a more-or-less customary fashion, plus the right to make | |
| 319 | reasonable modifications. | |
| 320 | ||
| 321 | Definitions: | |
| 322 | ||
| 323 | "Package" refers to the collection of files distributed by the | |
| 324 | Copyright Holder, and derivatives of that collection of files | |
| 325 | created through textual modification. | |
| 326 | ||
| 327 | "Standard Version" refers to such a Package if it has not been | |
| 328 | modified, or has been modified in accordance with the wishes | |
| 329 | of the Copyright Holder as specified below. | |
| 330 | ||
| 331 | "Copyright Holder" is whoever is named in the copyright or | |
| 332 | copyrights for the package. | |
| 333 | ||
| 334 | "You" is you, if you're thinking about copying or distributing | |
| 335 | this Package. | |
| 336 | ||
| 337 | "Reasonable copying fee" is whatever you can justify on the | |
| 338 | basis of media cost, duplication charges, time of people involved, | |
| 339 | and so on. (You will not be required to justify it to the | |
| 340 | Copyright Holder, but only to the computing community at large | |
| 341 | as a market that must bear the fee.) | |
| 342 | ||
| 343 | "Freely Available" means that no fee is charged for the item | |
| 344 | itself, though there may be fees involved in handling the item. | |
| 345 | It also means that recipients of the item may redistribute it | |
| 346 | under the same conditions they received it. | |
| 347 | ||
| 348 | 1. You may make and give away verbatim copies of the source form of the | |
| 349 | Standard Version of this Package without restriction, provided that you | |
| 350 | duplicate all of the original copyright notices and associated disclaimers. | |
| 351 | ||
| 352 | 2. You may apply bug fixes, portability fixes and other modifications | |
| 353 | derived from the Public Domain or from the Copyright Holder. A Package | |
| 354 | modified in such a way shall still be considered the Standard Version. | |
| 355 | ||
| 356 | 3. You may otherwise modify your copy of this Package in any way, provided | |
| 357 | that you insert a prominent notice in each changed file stating how and | |
| 358 | when you changed that file, and provided that you do at least ONE of the | |
| 359 | following: | |
| 360 | ||
| 361 | a) place your modifications in the Public Domain or otherwise make them | |
| 362 | Freely Available, such as by posting said modifications to Usenet or | |
| 363 | an equivalent medium, or placing the modifications on a major archive | |
| 364 | site such as uunet.uu.net, or by allowing the Copyright Holder to include | |
| 365 | your modifications in the Standard Version of the Package. | |
| 366 | ||
| 367 | b) use the modified Package only within your corporation or organization. | |
| 368 | ||
| 369 | c) rename any non-standard executables so the names do not conflict | |
| 370 | with standard executables, which must also be provided, and provide | |
| 371 | a separate manual page for each non-standard executable that clearly | |
| 372 | documents how it differs from the Standard Version. | |
| 373 | ||
| 374 | d) make other distribution arrangements with the Copyright Holder. | |
| 375 | ||
| 376 | 4. You may distribute the programs of this Package in object code or | |
| 377 | executable form, provided that you do at least ONE of the following: | |
| 378 | ||
| 379 | a) distribute a Standard Version of the executables and library files, | |
| 380 | together with instructions (in the manual page or equivalent) on where | |
| 381 | to get the Standard Version. | |
| 382 | ||
| 383 | b) accompany the distribution with the machine-readable source of | |
| 384 | the Package with your modifications. | |
| 385 | ||
| 386 | c) give non-standard executables non-standard names, and clearly | |
| 387 | document the differences in manual pages (or equivalent), together | |
| 388 | with instructions on where to get the Standard Version. | |
| 389 | ||
| 390 | d) make other distribution arrangements with the Copyright Holder. | |
| 391 | ||
| 392 | 5. You may charge a reasonable copying fee for any distribution of this | |
| 393 | Package. You may charge any fee you choose for support of this | |
| 394 | Package. You may not charge a fee for this Package itself. However, | |
| 395 | you may distribute this Package in aggregate with other (possibly | |
| 396 | commercial) programs as part of a larger (possibly commercial) software | |
| 397 | distribution provided that you do not advertise this Package as a | |
| 398 | product of your own. You may embed this Package's interpreter within | |
| 399 | an executable of yours (by linking); this shall be construed as a mere | |
| 400 | form of aggregation, provided that the complete Standard Version of the | |
| 401 | interpreter is so embedded. | |
| 402 | ||
| 403 | 6. The scripts and library files supplied as input to or produced as | |
| 404 | output from the programs of this Package do not automatically fall | |
| 405 | under the copyright of this Package, but belong to whoever generated | |
| 406 | them, and may be sold commercially, and may be aggregated with this | |
| 407 | Package. If such scripts or library files are aggregated with this | |
| 408 | Package via the so-called "undump" or "unexec" methods of producing a | |
| 409 | binary executable image, then distribution of such an image shall | |
| 410 | neither be construed as a distribution of this Package nor shall it | |
| 411 | fall under the restrictions of Paragraphs 3 and 4, provided that you do | |
| 412 | not represent such an executable image as a Standard Version of this | |
| 413 | Package. | |
| 414 | ||
| 415 | 7. C subroutines (or comparably compiled subroutines in other | |
| 416 | languages) supplied by you and linked into this Package in order to | |
| 417 | emulate subroutines and variables of the language defined by this | |
| 418 | Package shall not be considered part of this Package, but are the | |
| 419 | equivalent of input as in Paragraph 6, provided these subroutines do | |
| 420 | not change the language in any way that would cause it to fail the | |
| 421 | regression tests for the language. | |
| 422 | ||
