| 1 : | Isibaar | 6 | GNU GENERAL PUBLIC LICENSE |
| 2 : | Version 2, June 1991 | ||
| 3 : | |||
| 4 : | Copyright (C) 1989, 1991 Free Software Foundation, Inc. | ||
| 5 : | 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA | ||
| 6 : | Everyone is permitted to copy and distribute verbatim copies | ||
| 7 : | of this license document, but changing it is not allowed. | ||
| 8 : | |||
| 9 : | Preamble | ||
| 10 : | |||
| 11 : | The licenses for most software are designed to take away your | ||
| 12 : | freedom to share and change it. By contrast, the GNU General Public | ||
| 13 : | License is intended to guarantee your freedom to share and change free | ||
| 14 : | software--to make sure the software is free for all its users. This | ||
| 15 : | General Public License applies to most of the Free Software | ||
| 16 : | Foundation's software and to any other program whose authors commit to | ||
| 17 : | using it. (Some other Free Software Foundation software is covered by | ||
| 18 : | the GNU Library General Public License instead.) You can apply it to | ||
| 19 : | your programs, too. | ||
| 20 : | |||
| 21 : | When we speak of free software, we are referring to freedom, not | ||
| 22 : | price. Our General Public Licenses are designed to make sure that you | ||
| 23 : | have the freedom to distribute copies of free software (and charge for | ||
| 24 : | this service if you wish), that you receive source code or can get it | ||
| 25 : | if you want it, that you can change the software or use pieces of it | ||
| 26 : | in new free programs; and that you know you can do these things. | ||
| 27 : | |||
| 28 : | To protect your rights, we need to make restrictions that forbid | ||
| 29 : | anyone to deny you these rights or to ask you to surrender the rights. | ||
| 30 : | These restrictions translate to certain responsibilities for you if you | ||
| 31 : | distribute copies of the software, or if you modify it. | ||
| 32 : | |||
| 33 : | For example, if you distribute copies of such a program, whether | ||
| 34 : | gratis or for a fee, you must give the recipients all the rights that | ||
| 35 : | you have. You must make sure that they, too, receive or can get the | ||
| 36 : | source code. And you must show them these terms so they know their | ||
| 37 : | rights. | ||
| 38 : | |||
| 39 : | We protect your rights with two steps: (1) copyright the software, and | ||
| 40 : | (2) offer you this license which gives you legal permission to copy, | ||
| 41 : | distribute and/or modify the software. | ||
| 42 : | |||
| 43 : | Also, for each author's protection and ours, we want to make certain | ||
| 44 : | that everyone understands that there is no warranty for this free | ||
| 45 : | software. If the software is modified by someone else and passed on, we | ||
| 46 : | want its recipients to know that what they have is not the original, so | ||
| 47 : | that any problems introduced by others will not reflect on the original | ||
| 48 : | authors' reputations. | ||
| 49 : | |||
| 50 : | Finally, any free program is threatened constantly by software | ||
| 51 : | patents. We wish to avoid the danger that redistributors of a free | ||
| 52 : | program will individually obtain patent licenses, in effect making the | ||
| 53 : | program proprietary. To prevent this, we have made it clear that any | ||
| 54 : | patent must be licensed for everyone's free use or not licensed at all. | ||
| 55 : | |||
| 56 : | The precise terms and conditions for copying, distribution and | ||
| 57 : | modification follow. | ||
| 58 : | |||
| 59 : | GNU GENERAL PUBLIC LICENSE | ||
| 60 : | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION | ||
| 61 : | |||
| 62 : | 0. This License applies to any program or other work which contains | ||
| 63 : | a notice placed by the copyright holder saying it may be distributed | ||
| 64 : | under the terms of this General Public License. The "Program", below, | ||
| 65 : | refers to any such program or work, and a "work based on the Program" | ||
| 66 : | means either the Program or any derivative work under copyright law: | ||
| 67 : | that is to say, a work containing the Program or a portion of it, | ||
| 68 : | either verbatim or with modifications and/or translated into another | ||
| 69 : | language. (Hereinafter, translation is included without limitation in | ||
| 70 : | the term "modification".) Each licensee is addressed as "you". | ||
| 71 : | |||
| 72 : | Activities other than copying, distribution and modification are not | ||
| 73 : | covered by this License; they are outside its scope. The act of | ||
| 74 : | running the Program is not restricted, and the output from the Program | ||
| 75 : | is covered only if its contents constitute a work based on the | ||
| 76 : | Program (independent of having been made by running the Program). | ||
| 77 : | Whether that is true depends on what the Program does. | ||
| 78 : | |||
| 79 : | 1. You may copy and distribute verbatim copies of the Program's | ||
| 80 : | source code as you receive it, in any medium, provided that you | ||
| 81 : | conspicuously and appropriately publish on each copy an appropriate | ||
| 82 : | copyright notice and disclaimer of warranty; keep intact all the | ||
| 83 : | notices that refer to this License and to the absence of any warranty; | ||
| 84 : | and give any other recipients of the Program a copy of this License | ||
| 85 : | along with the Program. | ||
| 86 : | |||
| 87 : | You may charge a fee for the physical act of transferring a copy, and | ||
| 88 : | you may at your option offer warranty protection in exchange for a fee. | ||
| 89 : | |||
| 90 : | 2. You may modify your copy or copies of the Program or any portion | ||
| 91 : | of it, thus forming a work based on the Program, and copy and | ||
| 92 : | distribute such modifications or work under the terms of Section 1 | ||
| 93 : | above, provided that you also meet all of these conditions: | ||
| 94 : | |||
| 95 : | a) You must cause the modified files to carry prominent notices | ||
| 96 : | stating that you changed the files and the date of any change. | ||
| 97 : | |||
| 98 : | b) You must cause any work that you distribute or publish, that in | ||
| 99 : | whole or in part contains or is derived from the Program or any | ||
| 100 : | part thereof, to be licensed as a whole at no charge to all third | ||
| 101 : | parties under the terms of this License. | ||
| 102 : | |||
| 103 : | c) If the modified program normally reads commands interactively | ||
| 104 : | when run, you must cause it, when started running for such | ||
| 105 : | interactive use in the most ordinary way, to print or display an | ||
| 106 : | announcement including an appropriate copyright notice and a | ||
| 107 : | notice that there is no warranty (or else, saying that you provide | ||
| 108 : | a warranty) and that users may redistribute the program under | ||
| 109 : | these conditions, and telling the user how to view a copy of this | ||
| 110 : | License. (Exception: if the Program itself is interactive but | ||
| 111 : | does not normally print such an announcement, your work based on | ||
| 112 : | the Program is not required to print an announcement.) | ||
| 113 : | |||
| 114 : | These requirements apply to the modified work as a whole. If | ||
| 115 : | identifiable sections of that work are not derived from the Program, | ||
| 116 : | and can be reasonably considered independent and separate works in | ||
| 117 : | themselves, then this License, and its terms, do not apply to those | ||
| 118 : | sections when you distribute them as separate works. But when you | ||
| 119 : | distribute the same sections as part of a whole which is a work based | ||
| 120 : | on the Program, the distribution of the whole must be on the terms of | ||
| 121 : | 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 | ||
| 125 : | your rights to work written entirely by you; rather, the intent is to | ||
| 126 : | exercise the right to control the distribution of derivative or | ||
| 127 : | collective works based on the Program. | ||
| 128 : | |||
| 129 : | In addition, mere aggregation of another work not based on the Program | ||
| 130 : | with the Program (or with a work based on the Program) on a volume of | ||
| 131 : | a storage or distribution medium does not bring the other work under | ||
| 132 : | the scope of this License. | ||
| 133 : | |||
| 134 : | 3. You may copy and distribute the Program (or a work based on it, | ||
| 135 : | under Section 2) in object code or executable form under the terms of | ||
| 136 : | Sections 1 and 2 above provided that you also do one of the following: | ||
| 137 : | |||
| 138 : | a) Accompany it with the complete corresponding machine-readable | ||
| 139 : | source code, which must be distributed under the terms of Sections | ||
| 140 : | 1 and 2 above on a medium customarily used for software interchange; or, | ||
| 141 : | |||
| 142 : | b) Accompany it with a written offer, valid for at least three | ||
| 143 : | years, to give any third party, for a charge no more than your | ||
| 144 : | cost of physically performing source distribution, a complete | ||
| 145 : | machine-readable copy of the corresponding source code, to be | ||
| 146 : | distributed under the terms of Sections 1 and 2 above on a medium | ||
| 147 : | customarily used for software interchange; or, | ||
| 148 : | |||
| 149 : | c) Accompany it with the information you received as to the offer | ||
| 150 : | to distribute corresponding source code. (This alternative is | ||
| 151 : | allowed only for noncommercial distribution and only if you | ||
| 152 : | received the program in object code or executable form with such | ||
| 153 : | an offer, in accord with Subsection b above.) | ||
| 154 : | |||
| 155 : | The source code for a work means the preferred form of the work for | ||
| 156 : | making modifications to it. For an executable work, complete source | ||
| 157 : | code means all the source code for all modules it contains, plus any | ||
| 158 : | associated interface definition files, plus the scripts used to | ||
| 159 : | control compilation and installation of the executable. However, as a | ||
| 160 : | special exception, the source code distributed need not include | ||
| 161 : | anything that is normally distributed (in either source or binary | ||
| 162 : | form) with the major components (compiler, kernel, and so on) of the | ||
| 163 : | operating system on which the executable runs, unless that component | ||
| 164 : | itself accompanies the executable. | ||
| 165 : | |||
| 166 : | If distribution of executable or object code is made by offering | ||
| 167 : | access to copy from a designated place, then offering equivalent | ||
| 168 : | access to copy the source code from the same place counts as | ||
| 169 : | distribution of the source code, even though third parties are not | ||
| 170 : | compelled to copy the source along with the object code. | ||
| 171 : | |||
| 172 : | 4. You may not copy, modify, sublicense, or distribute the Program | ||
| 173 : | except as expressly provided under this License. Any attempt | ||
| 174 : | otherwise to copy, modify, sublicense or distribute the Program is | ||
| 175 : | void, and will automatically terminate your rights under this License. | ||
| 176 : | However, parties who have received copies, or rights, from you under | ||
| 177 : | this License will not have their licenses terminated so long as such | ||
| 178 : | parties remain in full compliance. | ||
| 179 : | |||
| 180 : | 5. You are not required to accept this License, since you have not | ||
| 181 : | signed it. However, nothing else grants you permission to modify or | ||
| 182 : | distribute the Program or its derivative works. These actions are | ||
| 183 : | prohibited by law if you do not accept this License. Therefore, by | ||
| 184 : | modifying or distributing the Program (or any work based on the | ||
| 185 : | Program), you indicate your acceptance of this License to do so, and | ||
| 186 : | all its terms and conditions for copying, distributing or modifying | ||
| 187 : | the Program or works based on it. | ||
| 188 : | |||
| 189 : | 6. Each time you redistribute the Program (or any work based on the | ||
| 190 : | Program), the recipient automatically receives a license from the | ||
| 191 : | original licensor to copy, distribute or modify the Program subject to | ||
| 192 : | these terms and conditions. You may not impose any further | ||
| 193 : | restrictions on the recipients' exercise of the rights granted herein. | ||
| 194 : | You are not responsible for enforcing compliance by third parties to | ||
| 195 : | this License. | ||
| 196 : | |||
| 197 : | 7. If, as a consequence of a court judgment or allegation of patent | ||
| 198 : | infringement or for any other reason (not limited to patent issues), | ||
| 199 : | conditions are imposed on you (whether by court order, agreement or | ||
| 200 : | otherwise) that contradict the conditions of this License, they do not | ||
| 201 : | excuse you from the conditions of this License. If you cannot | ||
| 202 : | distribute so as to satisfy simultaneously your obligations under this | ||
| 203 : | License and any other pertinent obligations, then as a consequence you | ||
| 204 : | may not distribute the Program at all. For example, if a patent | ||
| 205 : | license would not permit royalty-free redistribution of the Program by | ||
| 206 : | all those who receive copies directly or indirectly through you, then | ||
| 207 : | the only way you could satisfy both it and this License would be to | ||
| 208 : | refrain entirely from distribution of the Program. | ||
| 209 : | |||
| 210 : | If any portion of this section is held invalid or unenforceable under | ||
| 211 : | any particular circumstance, the balance of the section is intended to | ||
| 212 : | apply and the section as a whole is intended to apply in other | ||
| 213 : | circumstances. | ||
| 214 : | |||
| 215 : | It is not the purpose of this section to induce you to infringe any | ||
| 216 : | patents or other property right claims or to contest validity of any | ||
| 217 : | such claims; this section has the sole purpose of protecting the | ||
| 218 : | integrity of the free software distribution system, which is | ||
| 219 : | implemented by public license practices. Many people have made | ||
| 220 : | generous contributions to the wide range of software distributed | ||
| 221 : | through that system in reliance on consistent application of that | ||
| 222 : | system; it is up to the author/donor to decide if he or she is willing | ||
| 223 : | to distribute software through any other system and a licensee cannot | ||
| 224 : | impose that choice. | ||
| 225 : | |||
| 226 : | This section is intended to make thoroughly clear what is believed to | ||
| 227 : | be a consequence of the rest of this License. | ||
| 228 : | |||
| 229 : | 8. If the distribution and/or use of the Program is restricted in | ||
| 230 : | certain countries either by patents or by copyrighted interfaces, the | ||
| 231 : | original copyright holder who places the Program under this License | ||
| 232 : | may add an explicit geographical distribution limitation excluding | ||
| 233 : | those countries, so that distribution is permitted only in or among | ||
| 234 : | countries not thus excluded. In such case, this License incorporates | ||
| 235 : | the limitation as if written in the body of this License. | ||
| 236 : | |||
| 237 : | 9. The Free Software Foundation may publish revised and/or new versions | ||
| 238 : | of the General Public License from time to time. Such new versions will | ||
| 239 : | be similar in spirit to the present version, but may differ in detail to | ||
| 240 : | address new problems or concerns. | ||
| 241 : | |||
| 242 : | Each version is given a distinguishing version number. If the Program | ||
| 243 : | specifies a version number of this License which applies to it and "any | ||
| 244 : | later version", you have the option of following the terms and conditions | ||
| 245 : | either of that version or of any later version published by the Free | ||
| 246 : | Software Foundation. If the Program does not specify a version number of | ||
| 247 : | this License, you may choose any version ever published by the Free Software | ||
| 248 : | Foundation. | ||
| 249 : | |||
| 250 : | 10. If you wish to incorporate parts of the Program into other free | ||
| 251 : | programs whose distribution conditions are different, write to the author | ||
| 252 : | to ask for permission. For software which is copyrighted by the Free | ||
| 253 : | Software Foundation, write to the Free Software Foundation; we sometimes | ||
| 254 : | make exceptions for this. Our decision will be guided by the two goals | ||
| 255 : | of preserving the free status of all derivatives of our free software and | ||
| 256 : | of promoting the sharing and reuse of software generally. | ||
| 257 : | |||
| 258 : | NO WARRANTY | ||
| 259 : | |||
| 260 : | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY | ||
| 261 : | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN | ||
| 262 : | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES | ||
| 263 : | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED | ||
| 264 : | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF | ||
| 265 : | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS | ||
| 266 : | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE | ||
| 267 : | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, | ||
| 268 : | REPAIR OR CORRECTION. | ||
| 269 : | |||
| 270 : | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | ||
| 271 : | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR | ||
| 272 : | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, | ||
| 273 : | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING | ||
| 274 : | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED | ||
| 275 : | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY | ||
| 276 : | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER | ||
| 277 : | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE | ||
| 278 : | POSSIBILITY OF SUCH DAMAGES. | ||
| 279 : | |||
| 280 : | END OF TERMS AND CONDITIONS | ||
| 281 : | |||
| 282 : | How to Apply These Terms to Your New Programs | ||
| 283 : | |||
| 284 : | If you develop a new program, and you want it to be of the greatest | ||
| 285 : | possible use to the public, the best way to achieve this is to make it | ||
| 286 : | free software which everyone can redistribute and change under these terms. | ||
| 287 : | |||
| 288 : | To do so, attach the following notices to the program. It is safest | ||
| 289 : | to attach them to the start of each source file to most effectively | ||
| 290 : | convey the exclusion of warranty; and each file should have at least | ||
| 291 : | the "copyright" line and a pointer to where the full notice is found. | ||
| 292 : | |||
| 293 : | <one line to give the program's name and a brief idea of what it does.> | ||
| 294 : | Copyright (C) <year> <name of author> | ||
| 295 : | |||
| 296 : | This program is free software; you can redistribute it and/or modify | ||
| 297 : | it under the terms of the GNU General Public License as published by | ||
| 298 : | the Free Software Foundation; either version 2 of the License, or | ||
| 299 : | (at your option) any later version. | ||
| 300 : | |||
| 301 : | This program is distributed in the hope that it will be useful, | ||
| 302 : | but WITHOUT ANY WARRANTY; without even the implied warranty of | ||
| 303 : | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | ||
| 304 : | GNU General Public License for more details. | ||
| 305 : | |||
| 306 : | You should have received a copy of the GNU General Public License | ||
| 307 : | along with this program; if not, write to the Free Software | ||
| 308 : | Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA | ||
| 309 : | |||
| 310 : | |||
| 311 : | Also add information on how to contact you by electronic and paper mail. | ||
| 312 : | |||
| 313 : | If the program is interactive, make it output a short notice like this | ||
| 314 : | when it starts in an interactive mode: | ||
| 315 : | |||
| 316 : | Gnomovision version 69, Copyright (C) year name of author | ||
| 317 : | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. | ||
| 318 : | This is free software, and you are welcome to redistribute it | ||
| 319 : | under certain conditions; type `show c' for details. | ||
| 320 : | |||
| 321 : | The hypothetical commands `show w' and `show c' should show the appropriate | ||
| 322 : | parts of the General Public License. Of course, the commands you use may | ||
| 323 : | be called something other than `show w' and `show c'; they could even be | ||
| 324 : | mouse-clicks or menu items--whatever suits your program. | ||
| 325 : | |||
| 326 : | You should also get your employer (if you work as a programmer) or your | ||
| 327 : | school, if any, to sign a "copyright disclaimer" for the program, if | ||
| 328 : | necessary. Here is a sample; alter the names: | ||
| 329 : | |||
| 330 : | Yoyodyne, Inc., hereby disclaims all copyright interest in the program | ||
| 331 : | `Gnomovision' (which makes passes at compilers) written by James Hacker. | ||
| 332 : | |||
| 333 : | <signature of Ty Coon>, 1 April 1989 | ||
| 334 : | Ty Coon, President of Vice | ||
| 335 : | |||
| 336 : | This General Public License does not permit incorporating your program into | ||
| 337 : | proprietary programs. If your program is a subroutine library, you may | ||
| 338 : | consider it more useful to permit linking proprietary applications with the | ||
| 339 : | library. If this is what you want to do, use the GNU Library General | ||
| 340 : | Public License instead of this License. |
