| 11 | The General Public License (GPL) |
---|
| 12 | Version 2, June 1991 |
---|
| 13 | |
---|
| 14 | Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, |
---|
| 15 | Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute |
---|
| 16 | verbatim copies of this license document, but changing it is not allowed. |
---|
| 17 | |
---|
| 18 | Preamble |
---|
| 19 | |
---|
| 20 | The licenses for most software are designed to take away your freedom to share |
---|
| 21 | and change it. By contrast, the GNU General Public License is intended to |
---|
| 22 | guarantee your freedom to share and change free software--to make sure the |
---|
| 23 | software is free for all its users. This General Public License applies to most of |
---|
| 24 | the Free Software Foundation's software and to any other program whose |
---|
| 25 | authors commit to using it. (Some other Free Software Foundation software is |
---|
| 26 | covered by the GNU Library General Public License instead.) You can apply it to |
---|
| 27 | your programs, too. |
---|
| 28 | |
---|
| 29 | When we speak of free software, we are referring to freedom, not price. Our |
---|
| 30 | General Public Licenses are designed to make sure that you have the freedom |
---|
| 31 | to distribute copies of free software (and charge for this service if you wish), that |
---|
| 32 | you receive source code or can get it if you want it, that you can change the |
---|
| 33 | software or use pieces of it in new free programs; and that you know you can do |
---|
| 34 | these things. |
---|
| 35 | |
---|
| 36 | To protect your rights, we need to make restrictions that forbid anyone to deny |
---|
| 37 | you these rights or to ask you to surrender the rights. These restrictions |
---|
| 38 | translate to certain responsibilities for you if you distribute copies of the |
---|
| 39 | software, or if you modify it. |
---|
| 40 | |
---|
| 41 | For example, if you distribute copies of such a program, whether gratis or for a |
---|
| 42 | fee, you must give the recipients all the rights that you have. You must make |
---|
| 43 | sure that they, too, receive or can get the source code. And you must show |
---|
| 44 | them these terms so they know their rights. |
---|
| 45 | |
---|
| 46 | We protect your rights with two steps: (1) copyright the software, and (2) offer |
---|
| 47 | you this license which gives you legal permission to copy, distribute and/or |
---|
| 48 | modify the software. |
---|
| 49 | |
---|
| 50 | Also, for each author's protection and ours, we want to make certain that |
---|
| 51 | everyone understands that there is no warranty for this free software. If the |
---|
| 52 | software is modified by someone else and passed on, we want its recipients to |
---|
| 53 | know that what they have is not the original, so that any problems introduced by |
---|
| 54 | others will not reflect on the original authors' reputations. |
---|
| 55 | |
---|
| 56 | Finally, any free program is threatened constantly by software patents. We wish |
---|
| 57 | to avoid the danger that redistributors of a free program will individually obtain |
---|
| 58 | patent licenses, in effect making the program proprietary. To prevent this, we |
---|
| 59 | have made it clear that any patent must be licensed for everyone's free use or |
---|
| 60 | not licensed at all. |
---|
| 61 | |
---|
| 62 | The precise terms and conditions for copying, distribution and modification |
---|
| 63 | follow. |
---|
| 64 | |
---|
| 65 | GNU GENERAL PUBLIC LICENSE |
---|
| 66 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND |
---|
| 67 | MODIFICATION |
---|
| 68 | |
---|
| 69 | 0. This License applies to any program or other work which contains a notice |
---|
| 70 | placed by the copyright holder saying it may be distributed under the terms of |
---|
| 71 | this General Public License. The "Program", below, refers to any such program |
---|
| 72 | or work, and a "work based on the Program" means either the Program or any |
---|
| 73 | derivative work under copyright law: that is to say, a work containing the |
---|
| 74 | Program or a portion of it, either verbatim or with modifications and/or translated |
---|
| 75 | into another language. (Hereinafter, translation is included without limitation in |
---|
| 76 | the term "modification".) Each licensee is addressed as "you". |
---|
| 77 | |
---|
| 78 | Activities other than copying, distribution and modification are not covered by |
---|
| 79 | this License; they are outside its scope. The act of running the Program is not |
---|
| 80 | restricted, and the output from the Program is covered only if its contents |
---|
| 81 | constitute a work based on the Program (independent of having been made by |
---|
| 82 | running the Program). Whether that is true depends on what the Program does. |
---|
| 83 | |
---|
| 84 | 1. You may copy and distribute verbatim copies of the Program's source code as |
---|
| 85 | you receive it, in any medium, provided that you conspicuously and appropriately |
---|
| 86 | publish on each copy an appropriate copyright notice and disclaimer of warranty; |
---|
| 87 | keep intact all the notices that refer to this License and to the absence of any |
---|
| 88 | warranty; and give any other recipients of the Program a copy of this License |
---|
| 89 | along with the Program. |
---|
| 90 | |
---|
| 91 | You may charge a fee for the physical act of transferring a copy, and you may at |
---|
| 92 | your option offer warranty protection in exchange for a fee. |
---|
| 93 | |
---|
| 94 | 2. You may modify your copy or copies of the Program or any portion of it, thus |
---|
| 95 | forming a work based on the Program, and copy and distribute such |
---|
| 96 | modifications or work under the terms of Section 1 above, provided that you also |
---|
| 97 | meet all of these conditions: |
---|
| 98 | |
---|
| 99 | a) You must cause the modified files to carry prominent notices stating that you |
---|
| 100 | changed the files and the date of any change. |
---|
| 101 | |
---|
| 102 | b) You must cause any work that you distribute or publish, that in whole or in |
---|
| 103 | part contains or is derived from the Program or any part thereof, to be licensed |
---|
| 104 | as a whole at no charge to all third parties under the terms of this License. |
---|
| 105 | |
---|
| 106 | c) If the modified program normally reads commands interactively when run, you |
---|
| 107 | must cause it, when started running for such interactive use in the most ordinary |
---|
| 108 | way, to print or display an announcement including an appropriate copyright |
---|
| 109 | notice and a notice that there is no warranty (or else, saying that you provide a |
---|
| 110 | warranty) and that users may redistribute the program under these conditions, |
---|
| 111 | and telling the user how to view a copy of this License. (Exception: if the |
---|
| 112 | Program itself is interactive but does not normally print such an announcement, |
---|
| 113 | your work based on the Program is not required to print an announcement.) |
---|
| 114 | |
---|
| 115 | These requirements apply to the modified work as a whole. If identifiable |
---|
| 116 | sections of that work are not derived from the Program, and can be reasonably |
---|
| 117 | considered independent and separate works in themselves, then this License, |
---|
| 118 | and its terms, do not apply to those sections when you distribute them as |
---|
| 119 | separate works. But when you distribute the same sections as part of a whole |
---|
| 120 | which is a work based on the Program, the distribution of the whole must be on |
---|
| 121 | the terms of this License, whose permissions for other licensees extend to the |
---|
| 122 | entire whole, and thus to each and every part regardless of who wrote it. |
---|
| 123 | |
---|
| 124 | Thus, it is not the intent of this section to claim rights or contest your rights to |
---|
| 125 | work written entirely by you; rather, the intent is to exercise the right to control |
---|
| 126 | the distribution of derivative or collective works based on the Program. |
---|
| 127 | |
---|
| 128 | In addition, mere aggregation of another work not based on the Program with the |
---|
| 129 | Program (or with a work based on the Program) on a volume of a storage or |
---|
| 130 | distribution medium does not bring the other work under the scope of this |
---|
| 131 | License. |
---|
| 132 | |
---|
| 133 | 3. You may copy and distribute the Program (or a work based on it, under |
---|
| 134 | Section 2) in object code or executable form under the terms of Sections 1 and 2 |
---|
| 135 | above provided that you also do one of the following: |
---|
| 136 | |
---|
| 137 | a) Accompany it with the complete corresponding machine-readable source |
---|
| 138 | code, which must be distributed under the terms of Sections 1 and 2 above on a |
---|
| 139 | medium customarily used for software interchange; or, |
---|
| 140 | |
---|
| 141 | b) Accompany it with a written offer, valid for at least three years, to give any |
---|
| 142 | third party, for a charge no more than your cost of physically performing source |
---|
| 143 | distribution, a complete machine-readable copy of the corresponding source |
---|
| 144 | code, to be distributed under the terms of Sections 1 and 2 above on a medium |
---|
| 145 | customarily used for software interchange; or, |
---|
| 146 | |
---|
| 147 | c) Accompany it with the information you received as to the offer to distribute |
---|
| 148 | corresponding source code. (This alternative is allowed only for noncommercial |
---|
| 149 | distribution and only if you received the program in object code or executable |
---|
| 150 | form with such an offer, in accord with Subsection b above.) |
---|
| 151 | |
---|
| 152 | The source code for a work means the preferred form of the work for making |
---|
| 153 | modifications to it. For an executable work, complete source code means all the |
---|
| 154 | source code for all modules it contains, plus any associated interface definition |
---|
| 155 | files, plus the scripts used to control compilation and installation of the |
---|
| 156 | executable. However, as a special exception, the source code distributed need |
---|
| 157 | not include anything that is normally distributed (in either source or binary form) |
---|
| 158 | with the major components (compiler, kernel, and so on) of the operating system |
---|
| 159 | on which the executable runs, unless that component itself accompanies the |
---|
| 160 | executable. |
---|
| 161 | |
---|
| 162 | If distribution of executable or object code is made by offering access to copy |
---|
| 163 | from a designated place, then offering equivalent access to copy the source |
---|
| 164 | code from the same place counts as distribution of the source code, even though |
---|
| 165 | third parties are not compelled to copy the source along with the object code. |
---|
| 166 | |
---|
| 167 | 4. You may not copy, modify, sublicense, or distribute the Program except as |
---|
| 168 | expressly provided under this License. Any attempt otherwise to copy, modify, |
---|
| 169 | sublicense or distribute the Program is void, and will automatically terminate |
---|
| 170 | your rights under this License. However, parties who have received copies, or |
---|
| 171 | rights, from you under this License will not have their licenses terminated so long |
---|
| 172 | as such parties remain in full compliance. |
---|
| 173 | |
---|
| 174 | 5. You are not required to accept this License, since you have not signed it. |
---|
| 175 | However, nothing else grants you permission to modify or distribute the Program |
---|
| 176 | or its derivative works. These actions are prohibited by law if you do not accept |
---|
| 177 | this License. Therefore, by modifying or distributing the Program (or any work |
---|
| 178 | based on the Program), you indicate your acceptance of this License to do so, |
---|
| 179 | and all its terms and conditions for copying, distributing or modifying the |
---|
| 180 | Program or works based on it. |
---|
| 181 | |
---|
| 182 | 6. Each time you redistribute the Program (or any work based on the Program), |
---|
| 183 | the recipient automatically receives a license from the original licensor to copy, |
---|
| 184 | distribute or modify the Program subject to these terms and conditions. You |
---|
| 185 | may not impose any further restrictions on the recipients' exercise of the rights |
---|
| 186 | granted herein. You are not responsible for enforcing compliance by third parties |
---|
| 187 | to this License. |
---|
| 188 | |
---|
| 189 | 7. If, as a consequence of a court judgment or allegation of patent infringement |
---|
| 190 | or for any other reason (not limited to patent issues), conditions are imposed on |
---|
| 191 | you (whether by court order, agreement or otherwise) that contradict the |
---|
| 192 | conditions of this License, they do not excuse you from the conditions of this |
---|
| 193 | License. If you cannot distribute so as to satisfy simultaneously your obligations |
---|
| 194 | under this License and any other pertinent obligations, then as a consequence |
---|
| 195 | you may not distribute the Program at all. For example, if a patent license would |
---|
| 196 | not permit royalty-free redistribution of the Program by all those who receive |
---|
| 197 | copies directly or indirectly through you, then the only way you could satisfy |
---|
| 198 | both it and this License would be to refrain entirely from distribution of the |
---|
| 199 | Program. |
---|
| 200 | |
---|
| 201 | If any portion of this section is held invalid or unenforceable under any particular |
---|
| 202 | circumstance, the balance of the section is intended to apply and the section as |
---|
| 203 | a whole is intended to apply in other circumstances. |
---|
| 204 | |
---|
| 205 | It is not the purpose of this section to induce you to infringe any patents or other |
---|
| 206 | property right claims or to contest validity of any such claims; this section has |
---|
| 207 | the sole purpose of protecting the integrity of the free software distribution |
---|
| 208 | system, which is implemented by public license practices. Many people have |
---|
| 209 | made generous contributions to the wide range of software distributed through |
---|
| 210 | that system in reliance on consistent application of that system; it is up to the |
---|
| 211 | author/donor to decide if he or she is willing to distribute software through any |
---|
| 212 | other system and a licensee cannot impose that choice. |
---|
| 213 | |
---|
| 214 | This section is intended to make thoroughly clear what is believed to be a |
---|
| 215 | consequence of the rest of this License. |
---|
| 216 | |
---|
| 217 | 8. If the distribution and/or use of the Program is restricted in certain countries |
---|
| 218 | either by patents or by copyrighted interfaces, the original copyright holder who |
---|
| 219 | places the Program under this License may add an explicit geographical |
---|
| 220 | distribution limitation excluding those countries, so that distribution is permitted |
---|
| 221 | only in or among countries not thus excluded. In such case, this License |
---|
| 222 | incorporates the limitation as if written in the body of this License. |
---|
| 223 | |
---|
| 224 | 9. The Free Software Foundation may publish revised and/or new versions of the |
---|
| 225 | General Public License from time to time. Such new versions will be similar in |
---|
| 226 | spirit to the present version, but may differ in detail to address new problems or |
---|
| 227 | concerns. |
---|
| 228 | |
---|
| 229 | Each version is given a distinguishing version number. If the Program specifies a |
---|
| 230 | version number of this License which applies to it and "any later version", you |
---|
| 231 | have the option of following the terms and conditions either of that version or of |
---|
| 232 | any later version published by the Free Software Foundation. If the Program does |
---|
| 233 | not specify a version number of this License, you may choose any version ever |
---|
| 234 | published by the Free Software Foundation. |
---|
| 235 | |
---|
| 236 | 10. If you wish to incorporate parts of the Program into other free programs |
---|
| 237 | whose distribution conditions are different, write to the author to ask for |
---|
| 238 | permission. For software which is copyrighted by the Free Software Foundation, |
---|
| 239 | write to the Free Software Foundation; we sometimes make exceptions for this. |
---|
| 240 | Our decision will be guided by the two goals of preserving the free status of all |
---|
| 241 | derivatives of our free software and of promoting the sharing and reuse of |
---|
| 242 | software generally. |
---|
| 243 | |
---|
| 244 | NO WARRANTY |
---|
| 245 | |
---|
| 246 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS |
---|
| 247 | NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY |
---|
| 248 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE |
---|
| 249 | COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM |
---|
| 250 | "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR |
---|
| 251 | IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
---|
| 252 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE |
---|
| 253 | ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE |
---|
| 254 | PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, |
---|
| 255 | YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR |
---|
| 256 | CORRECTION. |
---|
| 257 | |
---|
| 258 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED |
---|
| 259 | TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY |
---|
| 260 | WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS |
---|
| 261 | PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY |
---|
| 262 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES |
---|
| 263 | ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM |
---|
| 264 | (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING |
---|
| 265 | RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD |
---|
| 266 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY |
---|
| 267 | OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS |
---|
| 268 | BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. |
---|
| 269 | |
---|
| 270 | END OF TERMS AND CONDITIONS |

| 275 | The Artistic License |
---|
| 276 | |
---|
| 277 | Preamble |
---|
| 278 | |
---|
| 279 | The intent of this document is to state the conditions under which a Package |
---|
| 280 | may be copied, such that the Copyright Holder maintains some semblance of |
---|
| 281 | artistic control over the development of the package, while giving the users of the |
---|
| 282 | package the right to use and distribute the Package in a more-or-less customary |
---|
| 283 | fashion, plus the right to make reasonable modifications. |
---|
| 284 | |
---|
| 285 | Definitions: |
---|
| 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 | |
---|
| 305 | 1. You may make and give away verbatim copies of the source form of the |
---|
| 306 | Standard Version of this Package without restriction, provided that you duplicate |
---|
| 307 | all of the original copyright notices and associated disclaimers. |
---|
| 308 | |
---|
| 309 | 2. You may apply bug fixes, portability fixes and other modifications derived from |
---|
| 310 | the Public Domain or from the Copyright Holder. A Package modified in such a |
---|
| 311 | way shall still be considered the Standard Version. |
---|
| 312 | |
---|
| 313 | 3. You may otherwise modify your copy of this Package in any way, provided |
---|
| 314 | that you insert a prominent notice in each changed file stating how and when |
---|
| 315 | you 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 | |
---|
| 335 | 4. You may distribute the programs of this Package in object code or executable |
---|
| 336 | form, 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 | |
---|
| 353 | 5. You may charge a reasonable copying fee for any distribution of this Package. |
---|
