1Terms of Perl itself 2 3a) the GNU General Public License as published by the Free 4 Software Foundation; either version 1, or (at your option) any 5 later version, or 6b) the "Artistic License" 7 8--------------------------------------------------------------------------- 9 10The General Public License (GPL) 11Version 2, June 1991 12 13Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, 14Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute 15verbatim copies of this license document, but changing it is not allowed. 16 17Preamble 18 19The licenses for most software are designed to take away your freedom to share 20and change it. By contrast, the GNU General Public License is intended to 21guarantee your freedom to share and change free software--to make sure the 22software is free for all its users. This General Public License applies to most of 23the Free Software Foundation's software and to any other program whose 24authors commit to using it. (Some other Free Software Foundation software is 25covered by the GNU Library General Public License instead.) You can apply it to 26your programs, too. 27 28When we speak of free software, we are referring to freedom, not price. Our 29General Public Licenses are designed to make sure that you have the freedom 30to distribute copies of free software (and charge for this service if you wish), that 31you receive source code or can get it if you want it, that you can change the 32software or use pieces of it in new free programs; and that you know you can do 33these things. 34 35To protect your rights, we need to make restrictions that forbid anyone to deny 36you these rights or to ask you to surrender the rights. These restrictions 37translate to certain responsibilities for you if you distribute copies of the 38software, or if you modify it. 39 40For example, if you distribute copies of such a program, whether gratis or for a 41fee, you must give the recipients all the rights that you have. You must make 42sure that they, too, receive or can get the source code. And you must show 43them these terms so they know their rights. 44 45We protect your rights with two steps: (1) copyright the software, and (2) offer 46you this license which gives you legal permission to copy, distribute and/or 47modify the software. 48 49Also, for each author's protection and ours, we want to make certain that 50everyone understands that there is no warranty for this free software. If the 51software is modified by someone else and passed on, we want its recipients to 52know that what they have is not the original, so that any problems introduced by 53others will not reflect on the original authors' reputations. 54 55Finally, any free program is threatened constantly by software patents. We wish 56to avoid the danger that redistributors of a free program will individually obtain 57patent licenses, in effect making the program proprietary. To prevent this, we 58have made it clear that any patent must be licensed for everyone's free use or 59not licensed at all. 60 61The precise terms and conditions for copying, distribution and modification 62follow. 63 64GNU GENERAL PUBLIC LICENSE 65TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND 66MODIFICATION 67 680. This License applies to any program or other work which contains a notice 69placed by the copyright holder saying it may be distributed under the terms of 70this General Public License. The "Program", below, refers to any such program 71or work, and a "work based on the Program" means either the Program or any 72derivative work under copyright law: that is to say, a work containing the 73Program or a portion of it, either verbatim or with modifications and/or translated 74into another language. (Hereinafter, translation is included without limitation in 75the term "modification".) Each licensee is addressed as "you". 76 77Activities other than copying, distribution and modification are not covered by 78this License; they are outside its scope. The act of running the Program is not 79restricted, and the output from the Program is covered only if its contents 80constitute a work based on the Program (independent of having been made by 81running the Program). Whether that is true depends on what the Program does. 82 831. You may copy and distribute verbatim copies of the Program's source code as 84you receive it, in any medium, provided that you conspicuously and appropriately 85publish on each copy an appropriate copyright notice and disclaimer of warranty; 86keep intact all the notices that refer to this License and to the absence of any 87warranty; and give any other recipients of the Program a copy of this License 88along with the Program. 89 90You may charge a fee for the physical act of transferring a copy, and you may at 91your option offer warranty protection in exchange for a fee. 92 932. You may modify your copy or copies of the Program or any portion of it, thus 94forming a work based on the Program, and copy and distribute such 95modifications or work under the terms of Section 1 above, provided that you also 96meet all of these conditions: 97 98a) You must cause the modified files to carry prominent notices stating that you 99changed the files and the date of any change. 100 101b) You must cause any work that you distribute or publish, that in whole or in 102part contains or is derived from the Program or any part thereof, to be licensed 103as a whole at no charge to all third parties under the terms of this License. 104 105c) If the modified program normally reads commands interactively when run, you 106must cause it, when started running for such interactive use in the most ordinary 107way, to print or display an announcement including an appropriate copyright 108notice and a notice that there is no warranty (or else, saying that you provide a 109warranty) and that users may redistribute the program under these conditions, 110and telling the user how to view a copy of this License. (Exception: if the 111Program itself is interactive but does not normally print such an announcement, 112your work based on the Program is not required to print an announcement.) 113 114These requirements apply to the modified work as a whole. If identifiable 115sections of that work are not derived from the Program, and can be reasonably 116considered independent and separate works in themselves, then this License, 117and its terms, do not apply to those sections when you distribute them as 118separate works. But when you distribute the same sections as part of a whole 119which is a work based on the Program, the distribution of the whole must be on 120the terms of this License, whose permissions for other licensees extend to the 121entire whole, and thus to each and every part regardless of who wrote it. 122 123Thus, it is not the intent of this section to claim rights or contest your rights to 124work written entirely by you; rather, the intent is to exercise the right to control 125the distribution of derivative or collective works based on the Program. 126 127In addition, mere aggregation of another work not based on the Program with the 128Program (or with a work based on the Program) on a volume of a storage or 129distribution medium does not bring the other work under the scope of this 130License. 131 1323. You may copy and distribute the Program (or a work based on it, under 133Section 2) in object code or executable form under the terms of Sections 1 and 2 134above provided that you also do one of the following: 135 136a) Accompany it with the complete corresponding machine-readable source 137code, which must be distributed under the terms of Sections 1 and 2 above on a 138medium customarily used for software interchange; or, 139 140b) Accompany it with a written offer, valid for at least three years, to give any 141third party, for a charge no more than your cost of physically performing source 142distribution, a complete machine-readable copy of the corresponding source 143code, to be distributed under the terms of Sections 1 and 2 above on a medium 144customarily used for software interchange; or, 145 146c) Accompany it with the information you received as to the offer to distribute 147corresponding source code. (This alternative is allowed only for noncommercial 148distribution and only if you received the program in object code or executable 149form with such an offer, in accord with Subsection b above.) 150 151The source code for a work means the preferred form of the work for making 152modifications to it. For an executable work, complete source code means all the 153source code for all modules it contains, plus any associated interface definition 154files, plus the scripts used to control compilation and installation of the 155executable. However, as a special exception, the source code distributed need 156not include anything that is normally distributed (in either source or binary form) 157with the major components (compiler, kernel, and so on) of the operating system 158on which the executable runs, unless that component itself accompanies the 159executable. 160 161If distribution of executable or object code is made by offering access to copy 162from a designated place, then offering equivalent access to copy the source 163code from the same place counts as distribution of the source code, even though 164third parties are not compelled to copy the source along with the object code. 165 1664. You may not copy, modify, sublicense, or distribute the Program except as 167expressly provided under this License. Any attempt otherwise to copy, modify, 168sublicense or distribute the Program is void, and will automatically terminate 169your rights under this License. However, parties who have received copies, or 170rights, from you under this License will not have their licenses terminated so long 171as such parties remain in full compliance. 172 1735. You are not required to accept this License, since you have not signed it. 174However, nothing else grants you permission to modify or distribute the Program 175or its derivative works. These actions are prohibited by law if you do not accept 176this License. Therefore, by modifying or distributing the Program (or any work 177based on the Program), you indicate your acceptance of this License to do so, 178and all its terms and conditions for copying, distributing or modifying the 179Program or works based on it. 180 1816. Each time you redistribute the Program (or any work based on the Program), 182the recipient automatically receives a license from the original licensor to copy, 183distribute or modify the Program subject to these terms and conditions. You 184may not impose any further restrictions on the recipients' exercise of the rights 185granted herein. You are not responsible for enforcing compliance by third parties 186to this License. 187 1887. If, as a consequence of a court judgment or allegation of patent infringement 189or for any other reason (not limited to patent issues), conditions are imposed on 190you (whether by court order, agreement or otherwise) that contradict the 191conditions of this License, they do not excuse you from the conditions of this 192License. If you cannot distribute so as to satisfy simultaneously your obligations 193under this License and any other pertinent obligations, then as a consequence 194you may not distribute the Program at all. For example, if a patent license would 195not permit royalty-free redistribution of the Program by all those who receive 196copies directly or indirectly through you, then the only way you could satisfy 197both it and this License would be to refrain entirely from distribution of the 198Program. 199 200If any portion of this section is held invalid or unenforceable under any particular 201circumstance, the balance of the section is intended to apply and the section as 202a whole is intended to apply in other circumstances. 203 204It is not the purpose of this section to induce you to infringe any patents or other 205property right claims or to contest validity of any such claims; this section has 206the sole purpose of protecting the integrity of the free software distribution 207system, which is implemented by public license practices. Many people have 208made generous contributions to the wide range of software distributed through 209that system in reliance on consistent application of that system; it is up to the 210author/donor to decide if he or she is willing to distribute software through any 211other system and a licensee cannot impose that choice. 212 213This section is intended to make thoroughly clear what is believed to be a 214consequence of the rest of this License. 215 2168. If the distribution and/or use of the Program is restricted in certain countries 217either by patents or by copyrighted interfaces, the original copyright holder who 218places the Program under this License may add an explicit geographical 219distribution limitation excluding those countries, so that distribution is permitted 220only in or among countries not thus excluded. In such case, this License 221incorporates the limitation as if written in the body of this License. 222 2239. The Free Software Foundation may publish revised and/or new versions of the 224General Public License from time to time. Such new versions will be similar in 225spirit to the present version, but may differ in detail to address new problems or 226concerns. 227 228Each version is given a distinguishing version number. If the Program specifies a 229version number of this License which applies to it and "any later version", you 230have the option of following the terms and conditions either of that version or of 231any later version published by the Free Software Foundation. If the Program does 232not specify a version number of this License, you may choose any version ever 233published by the Free Software Foundation. 234 23510. If you wish to incorporate parts of the Program into other free programs 236whose distribution conditions are different, write to the author to ask for 237permission. For software which is copyrighted by the Free Software Foundation, 238write to the Free Software Foundation; we sometimes make exceptions for this. 239Our decision will be guided by the two goals of preserving the free status of all 240derivatives of our free software and of promoting the sharing and reuse of 241software generally. 242 243NO WARRANTY 244 24511. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS 246NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 247APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE 248COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM 249"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR 250IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 251MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE 252ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE 253PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, 254YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR 255CORRECTION. 256 25712. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED 258TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY 259WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS 260PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 261GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES 262ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM 263(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING 264RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 265PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY 266OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS 267BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 268 269END OF TERMS AND CONDITIONS 270 271 272--------------------------------------------------------------------------- 273 274The Artistic License 275 276Preamble 277 278The intent of this document is to state the conditions under which a Package 279may be copied, such that the Copyright Holder maintains some semblance of 280artistic control over the development of the package, while giving the users of the 281package the right to use and distribute the Package in a more-or-less customary 282fashion, plus the right to make reasonable modifications. 283 284Definitions: 285 286- "Package" refers to the collection of files distributed by the Copyright 287 Holder, and derivatives of that collection of files created through textual 288 modification. 289- "Standard Version" refers to such a Package if it has not been modified, 290 or has been modified in accordance with the wishes of the Copyright 291 Holder. 292- "Copyright Holder" is whoever is named in the copyright or copyrights for 293 the package. 294- "You" is you, if you're thinking about copying or distributing this Package. 295- "Reasonable copying fee" is whatever you can justify on the basis of 296 media cost, duplication charges, time of people involved, and so on. (You 297 will not be required to justify it to the Copyright Holder, but only to the 298 computing community at large as a market that must bear the fee.) 299- "Freely Available" means that no fee is charged for the item itself, though 300 there may be fees involved in handling the item. It also means that 301 recipients of the item may redistribute it under the same conditions they 302 received it. 303 3041. You may make and give away verbatim copies of the source form of the 305Standard Version of this Package without restriction, provided that you duplicate 306all of the original copyright notices and associated disclaimers. 307 3082. You may apply bug fixes, portability fixes and other modifications derived from 309the Public Domain or from the Copyright Holder. A Package modified in such a 310way shall still be considered the Standard Version. 311 3123. You may otherwise modify your copy of this Package in any way, provided 313that you insert a prominent notice in each changed file stating how and when 314you changed that file, and provided that you do at least ONE of the following: 315 316 a) place your modifications in the Public Domain or otherwise 317 make them Freely Available, such as by posting said modifications 318 to Usenet or an equivalent medium, or placing the modifications on 319 a major archive site such as ftp.uu.net, or by allowing the 320 Copyright Holder to include your modifications in the Standard 321 Version of the Package. 322 323 b) use the modified Package only within your corporation or 324 organization. 325 326 c) rename any non-standard executables so the names do not 327 conflict with standard executables, which must also be provided, 328 and provide a separate manual page for each non-standard 329 executable that clearly documents how it differs from the Standard 330 Version. 331 332 d) make other distribution arrangements with the Copyright Holder. 333 3344. You may distribute the programs of this Package in object code or executable 335form, provided that you do at least ONE of the following: 336 337 a) distribute a Standard Version of the executables and library 338 files, together with instructions (in the manual page or equivalent) 339 on where to get the Standard Version. 340 341 b) accompany the distribution with the machine-readable source of 342 the Package with your modifications. 343 344 c) accompany any non-standard executables with their 345 corresponding Standard Version executables, giving the 346 non-standard executables non-standard names, and clearly 347 documenting the differences in manual pages (or equivalent), 348 together with instructions on where to get the Standard Version. 349 350 d) make other distribution arrangements with the Copyright Holder. 351 3525. You may charge a reasonable copying fee for any distribution of this Package. 353You may charge any fee you choose for support of this Package. You may not 354charge a fee for this Package itself. However, you may distribute this Package in 355aggregate with other (possibly commercial) programs as part of a larger 356(possibly commercial) software distribution provided that you do not advertise 357this Package as a product of your own. 358 3596. The scripts and library files supplied as input to or produced as output from 360the programs of this Package do not automatically fall under the copyright of this 361Package, but belong to whomever generated them, and may be sold 362commercially, and may be aggregated with this Package. 363 3647. C or perl subroutines supplied by you and linked into this Package shall not 365be considered part of this Package. 366 3678. Aggregation of this Package with a commercial distribution is always permitted 368provided that the use of this Package is embedded; that is, when no overt attempt 369is made to make this Package's interfaces visible to the end user of the 370commercial distribution. Such use shall not be construed as a distribution of 371this Package. 372 3739. The name of the Copyright Holder may not be used to endorse or promote 374products derived from this software without specific prior written permission. 375 37610. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR 377IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED 378WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR 379PURPOSE. 380 381The End 382 383 384
