1 2Terms of Perl itself 3 4a) the GNU General Public License as published by the Free 5 Software Foundation; either version 1, or (at your option) any 6 later version, or 7b) the "Artistic License" 8 9---------------------------------------------------------------------------- 10 11The General Public License (GPL) 12Version 2, June 1991 13 14Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, 15Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute 16verbatim copies of this license document, but changing it is not allowed. 17 18Preamble 19 20The licenses for most software are designed to take away your freedom to share 21and change it. By contrast, the GNU General Public License is intended to 22guarantee your freedom to share and change free software--to make sure the 23software is free for all its users. This General Public License applies to most of 24the Free Software Foundation's software and to any other program whose 25authors commit to using it. (Some other Free Software Foundation software is 26covered by the GNU Library General Public License instead.) You can apply it to 27your programs, too. 28 29When we speak of free software, we are referring to freedom, not price. Our 30General Public Licenses are designed to make sure that you have the freedom 31to distribute copies of free software (and charge for this service if you wish), that 32you receive source code or can get it if you want it, that you can change the 33software or use pieces of it in new free programs; and that you know you can do 34these things. 35 36To protect your rights, we need to make restrictions that forbid anyone to deny 37you these rights or to ask you to surrender the rights. These restrictions 38translate to certain responsibilities for you if you distribute copies of the 39software, or if you modify it. 40 41For example, if you distribute copies of such a program, whether gratis or for a 42fee, you must give the recipients all the rights that you have. You must make 43sure that they, too, receive or can get the source code. And you must show 44them these terms so they know their rights. 45 46We protect your rights with two steps: (1) copyright the software, and (2) offer 47you this license which gives you legal permission to copy, distribute and/or 48modify the software. 49 50Also, for each author's protection and ours, we want to make certain that 51everyone understands that there is no warranty for this free software. If the 52software is modified by someone else and passed on, we want its recipients to 53know that what they have is not the original, so that any problems introduced by 54others will not reflect on the original authors' reputations. 55 56Finally, any free program is threatened constantly by software patents. We wish 57to avoid the danger that redistributors of a free program will individually obtain 58patent licenses, in effect making the program proprietary. To prevent this, we 59have made it clear that any patent must be licensed for everyone's free use or 60not licensed at all. 61 62The precise terms and conditions for copying, distribution and modification 63follow. 64 65GNU GENERAL PUBLIC LICENSE 66TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND 67MODIFICATION 68 690. This License applies to any program or other work which contains a notice 70placed by the copyright holder saying it may be distributed under the terms of 71this General Public License. The "Program", below, refers to any such program 72or work, and a "work based on the Program" means either the Program or any 73derivative work under copyright law: that is to say, a work containing the 74Program or a portion of it, either verbatim or with modifications and/or translated 75into another language. (Hereinafter, translation is included without limitation in 76the term "modification".) Each licensee is addressed as "you". 77 78Activities other than copying, distribution and modification are not covered by 79this License; they are outside its scope. The act of running the Program is not 80restricted, and the output from the Program is covered only if its contents 81constitute a work based on the Program (independent of having been made by 82running the Program). Whether that is true depends on what the Program does. 83 841. You may copy and distribute verbatim copies of the Program's source code as 85you receive it, in any medium, provided that you conspicuously and appropriately 86publish on each copy an appropriate copyright notice and disclaimer of warranty; 87keep intact all the notices that refer to this License and to the absence of any 88warranty; and give any other recipients of the Program a copy of this License 89along with the Program. 90 91You may charge a fee for the physical act of transferring a copy, and you may at 92your option offer warranty protection in exchange for a fee. 93 942. You may modify your copy or copies of the Program or any portion of it, thus 95forming a work based on the Program, and copy and distribute such 96modifications or work under the terms of Section 1 above, provided that you also 97meet all of these conditions: 98 99a) You must cause the modified files to carry prominent notices stating that you 100changed the files and the date of any change. 101 102b) You must cause any work that you distribute or publish, that in whole or in 103part contains or is derived from the Program or any part thereof, to be licensed 104as a whole at no charge to all third parties under the terms of this License. 105 106c) If the modified program normally reads commands interactively when run, you 107must cause it, when started running for such interactive use in the most ordinary 108way, to print or display an announcement including an appropriate copyright 109notice and a notice that there is no warranty (or else, saying that you provide a 110warranty) and that users may redistribute the program under these conditions, 111and telling the user how to view a copy of this License. (Exception: if the 112Program itself is interactive but does not normally print such an announcement, 113your work based on the Program is not required to print an announcement.) 114 115These requirements apply to the modified work as a whole. If identifiable 116sections of that work are not derived from the Program, and can be reasonably 117considered independent and separate works in themselves, then this License, 118and its terms, do not apply to those sections when you distribute them as 119separate works. But when you distribute the same sections as part of a whole 120which is a work based on the Program, the distribution of the whole must be on 121the terms of this License, whose permissions for other licensees extend to the 122entire whole, and thus to each and every part regardless of who wrote it. 123 124Thus, it is not the intent of this section to claim rights or contest your rights to 125work written entirely by you; rather, the intent is to exercise the right to control 126the distribution of derivative or collective works based on the Program. 127 128In addition, mere aggregation of another work not based on the Program with the 129Program (or with a work based on the Program) on a volume of a storage or 130distribution medium does not bring the other work under the scope of this 131License. 132 1333. You may copy and distribute the Program (or a work based on it, under 134Section 2) in object code or executable form under the terms of Sections 1 and 2 135above provided that you also do one of the following: 136 137a) Accompany it with the complete corresponding machine-readable source 138code, which must be distributed under the terms of Sections 1 and 2 above on a 139medium customarily used for software interchange; or, 140 141b) Accompany it with a written offer, valid for at least three years, to give any 142third party, for a charge no more than your cost of physically performing source 143distribution, a complete machine-readable copy of the corresponding source 144code, to be distributed under the terms of Sections 1 and 2 above on a medium 145customarily used for software interchange; or, 146 147c) Accompany it with the information you received as to the offer to distribute 148corresponding source code. (This alternative is allowed only for noncommercial 149distribution and only if you received the program in object code or executable 150form with such an offer, in accord with Subsection b above.) 151 152The source code for a work means the preferred form of the work for making 153modifications to it. For an executable work, complete source code means all the 154source code for all modules it contains, plus any associated interface definition 155files, plus the scripts used to control compilation and installation of the 156executable. However, as a special exception, the source code distributed need 157not include anything that is normally distributed (in either source or binary form) 158with the major components (compiler, kernel, and so on) of the operating system 159on which the executable runs, unless that component itself accompanies the 160executable. 161 162If distribution of executable or object code is made by offering access to copy 163from a designated place, then offering equivalent access to copy the source 164code from the same place counts as distribution of the source code, even though 165third parties are not compelled to copy the source along with the object code. 166 1674. You may not copy, modify, sublicense, or distribute the Program except as 168expressly provided under this License. Any attempt otherwise to copy, modify, 169sublicense or distribute the Program is void, and will automatically terminate 170your rights under this License. However, parties who have received copies, or 171rights, from you under this License will not have their licenses terminated so long 172as such parties remain in full compliance. 173 1745. You are not required to accept this License, since you have not signed it. 175However, nothing else grants you permission to modify or distribute the Program 176or its derivative works. These actions are prohibited by law if you do not accept 177this License. Therefore, by modifying or distributing the Program (or any work 178based on the Program), you indicate your acceptance of this License to do so, 179and all its terms and conditions for copying, distributing or modifying the 180Program or works based on it. 181 1826. Each time you redistribute the Program (or any work based on the Program), 183the recipient automatically receives a license from the original licensor to copy, 184distribute or modify the Program subject to these terms and conditions. You 185may not impose any further restrictions on the recipients' exercise of the rights 186granted herein. You are not responsible for enforcing compliance by third parties 187to this License. 188 1897. If, as a consequence of a court judgment or allegation of patent infringement 190or for any other reason (not limited to patent issues), conditions are imposed on 191you (whether by court order, agreement or otherwise) that contradict the 192conditions of this License, they do not excuse you from the conditions of this 193License. If you cannot distribute so as to satisfy simultaneously your obligations 194under this License and any other pertinent obligations, then as a consequence 195you may not distribute the Program at all. For example, if a patent license would 196not permit royalty-free redistribution of the Program by all those who receive 197copies directly or indirectly through you, then the only way you could satisfy 198both it and this License would be to refrain entirely from distribution of the 199Program. 200 201If any portion of this section is held invalid or unenforceable under any particular 202circumstance, the balance of the section is intended to apply and the section as 203a whole is intended to apply in other circumstances. 204 205It is not the purpose of this section to induce you to infringe any patents or other 206property right claims or to contest validity of any such claims; this section has 207the sole purpose of protecting the integrity of the free software distribution 208system, which is implemented by public license practices. Many people have 209made generous contributions to the wide range of software distributed through 210that system in reliance on consistent application of that system; it is up to the 211author/donor to decide if he or she is willing to distribute software through any 212other system and a licensee cannot impose that choice. 213 214This section is intended to make thoroughly clear what is believed to be a 215consequence of the rest of this License. 216 2178. If the distribution and/or use of the Program is restricted in certain countries 218either by patents or by copyrighted interfaces, the original copyright holder who 219places the Program under this License may add an explicit geographical 220distribution limitation excluding those countries, so that distribution is permitted 221only in or among countries not thus excluded. In such case, this License 222incorporates the limitation as if written in the body of this License. 223 2249. The Free Software Foundation may publish revised and/or new versions of the 225General Public License from time to time. Such new versions will be similar in 226spirit to the present version, but may differ in detail to address new problems or 227concerns. 228 229Each version is given a distinguishing version number. If the Program specifies a 230version number of this License which applies to it and "any later version", you 231have the option of following the terms and conditions either of that version or of 232any later version published by the Free Software Foundation. If the Program does 233not specify a version number of this License, you may choose any version ever 234published by the Free Software Foundation. 235 23610. If you wish to incorporate parts of the Program into other free programs 237whose distribution conditions are different, write to the author to ask for 238permission. For software which is copyrighted by the Free Software Foundation, 239write to the Free Software Foundation; we sometimes make exceptions for this. 240Our decision will be guided by the two goals of preserving the free status of all 241derivatives of our free software and of promoting the sharing and reuse of 242software generally. 243 244NO WARRANTY 245 24611. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS 247NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 248APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE 249COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM 250"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR 251IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 252MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE 253ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE 254PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, 255YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR 256CORRECTION. 257 25812. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED 259TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY 260WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS 261PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 262GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES 263ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM 264(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING 265RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 266PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY 267OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS 268BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 269 270END OF TERMS AND CONDITIONS 271 272 273---------------------------------------------------------------------------- 274 275The Artistic License 276 277Preamble 278 279The intent of this document is to state the conditions under which a Package 280may be copied, such that the Copyright Holder maintains some semblance of 281artistic control over the development of the package, while giving the users of the 282package the right to use and distribute the Package in a more-or-less customary 283fashion, plus the right to make reasonable modifications. 284 285Definitions: 286 287- "Package" refers to the collection of files distributed by the Copyright 288 Holder, and derivatives of that collection of files created through textual 289 modification. 290- "Standard Version" refers to such a Package if it has not been modified, 291 or has been modified in accordance with the wishes of the Copyright 292 Holder. 293- "Copyright Holder" is whoever is named in the copyright or copyrights for 294 the package. 295- "You" is you, if you're thinking about copying or distributing this Package. 296- "Reasonable copying fee" is whatever you can justify on the basis of 297 media cost, duplication charges, time of people involved, and so on. (You 298 will not be required to justify it to the Copyright Holder, but only to the 299 computing community at large as a market that must bear the fee.) 300- "Freely Available" means that no fee is charged for the item itself, though 301 there may be fees involved in handling the item. It also means that 302 recipients of the item may redistribute it under the same conditions they 303 received it. 304 3051. You may make and give away verbatim copies of the source form of the 306Standard Version of this Package without restriction, provided that you duplicate 307all of the original copyright notices and associated disclaimers. 308 3092. You may apply bug fixes, portability fixes and other modifications derived from 310the Public Domain or from the Copyright Holder. A Package modified in such a 311way shall still be considered the Standard Version. 312 3133. You may otherwise modify your copy of this Package in any way, provided 314that you insert a prominent notice in each changed file stating how and when 315you changed that file, and provided that you do at least ONE of the following: 316 317 a) place your modifications in the Public Domain or otherwise 318 make them Freely Available, such as by posting said modifications 319 to Usenet or an equivalent medium, or placing the modifications on 320 a major archive site such as ftp.uu.net, or by allowing the 321 Copyright Holder to include your modifications in the Standard 322 Version of the Package. 323 324 b) use the modified Package only within your corporation or 325 organization. 326 327 c) rename any non-standard executables so the names do not 328 conflict with standard executables, which must also be provided, 329 and provide a separate manual page for each non-standard 330 executable that clearly documents how it differs from the Standard 331 Version. 332 333 d) make other distribution arrangements with the Copyright Holder. 334 3354. You may distribute the programs of this Package in object code or executable 336form, provided that you do at least ONE of the following: 337 338 a) distribute a Standard Version of the executables and library 339 files, together with instructions (in the manual page or equivalent) 340 on where to get the Standard Version. 341 342 b) accompany the distribution with the machine-readable source of 343 the Package with your modifications. 344 345 c) accompany any non-standard executables with their 346 corresponding Standard Version executables, giving the 347 non-standard executables non-standard names, and clearly 348 documenting the differences in manual pages (or equivalent), 349 together with instructions on where to get the Standard Version. 350 351 d) make other distribution arrangements with the Copyright Holder. 352 3535. You may charge a reasonable copying fee for any distribution of this Package. 354You may charge any fee you choose for support of this Package. You may not 355charge a fee for this Package itself. However, you may distribute this Package in 356aggregate with other (possibly commercial) programs as part of a larger 357(possibly commercial) software distribution provided that you do not advertise 358this Package as a product of your own. 359 3606. The scripts and library files supplied as input to or produced as output from 361the programs of this Package do not automatically fall under the copyright of this 362Package, but belong to whomever generated them, and may be sold 363commercially, and may be aggregated with this Package. 364 3657. C or perl subroutines supplied by you and linked into this Package shall not 366be considered part of this Package. 367 3688. The name of the Copyright Holder may not be used to endorse or promote 369products derived from this software without specific prior written permission. 370 3719. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR 372IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED 373WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR 374PURPOSE. 375 376The End 377 378 379
