| 24 | GNU GENERAL PUBLIC LICENSE<br> |
| 25 | Version 2, June 1991<br> |
| 26 | <br> |
| 27 | Copyright (C) 1989, 1991 Free Software Foundation, Inc.,<br> |
| 28 | 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA<br> |
| 29 | Everyone is permitted to copy and distribute verbatim copies<br> |
| 30 | of this license document, but changing it is not allowed.<br> |
| 31 | <br> |
| 32 | Preamble<br> |
| 33 | <br> |
| 34 | The licenses for most software are designed to take away your<br> |
| 35 | freedom to share and change it. By contrast, the GNU General Public<br> |
| 36 | License is intended to guarantee your freedom to share and change free<br> |
| 37 | software--to make sure the software is free for all its users. This<br> |
| 38 | General Public License applies to most of the Free Software<br> |
| 39 | Foundation's software and to any other program whose authors commit to<br> |
| 40 | using it. (Some other Free Software Foundation software is covered by<br> |
| 41 | the GNU Lesser General Public License instead.) You can apply it to<br> |
| 42 | your programs, too.<br> |
| 43 | <br> |
| 44 | When we speak of free software, we are referring to freedom, not<br> |
| 45 | price. Our General Public Licenses are designed to make sure that you<br> |
| 46 | have the freedom to distribute copies of free software (and charge for<br> |
| 47 | this service if you wish), that you receive source code or can get it<br> |
| 48 | if you want it, that you can change the software or use pieces of it<br> |
| 49 | in new free programs; and that you know you can do these things.<br> |
| 50 | <br> |
| 51 | To protect your rights, we need to make restrictions that forbid<br> |
| 52 | anyone to deny you these rights or to ask you to surrender the rights.<br> |
| 53 | These restrictions translate to certain responsibilities for you if you<br> |
| 54 | distribute copies of the software, or if you modify it.<br> |
| 55 | <br> |
| 56 | For example, if you distribute copies of such a program, whether<br> |
| 57 | gratis or for a fee, you must give the recipients all the rights that<br> |
| 58 | you have. You must make sure that they, too, receive or can get the<br> |
| 59 | source code. And you must show them these terms so they know their<br> |
| 60 | rights.<br> |
| 61 | <br> |
| 62 | We protect your rights with two steps: (1) copyright the software, and<br> |
| 63 | (2) offer you this license which gives you legal permission to copy,<br> |
| 64 | distribute and/or modify the software.<br> |
| 65 | <br> |
| 66 | Also, for each author's protection and ours, we want to make certain<br> |
| 67 | that everyone understands that there is no warranty for this free<br> |
| 68 | software. If the software is modified by someone else and passed on, we<br> |
| 69 | want its recipients to know that what they have is not the original, so<br> |
| 70 | that any problems introduced by others will not reflect on the original<br> |
| 71 | authors' reputations.<br> |
| 72 | <br> |
| 73 | Finally, any free program is threatened constantly by software<br> |
| 74 | patents. We wish to avoid the danger that redistributors of a free<br> |
| 75 | program will individually obtain patent licenses, in effect making the<br> |
| 76 | program proprietary. To prevent this, we have made it clear that any<br> |
| 77 | patent must be licensed for everyone's free use or not licensed at all.<br> |
| 78 | <br> |
| 79 | The precise terms and conditions for copying, distribution and<br> |
| 80 | modification follow.<br> |
| 81 | <br> |
| 82 | GNU GENERAL PUBLIC LICENSE<br> |
| 83 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION<br> |
| 84 | <br> |
| 85 | 0. This License applies to any program or other work which contains<br> |
| 86 | a notice placed by the copyright holder saying it may be distributed<br> |
| 87 | under the terms of this General Public License. The "Program", below,<br> |
| 88 | refers to any such program or work, and a "work based on the Program"<br> |
| 89 | means either the Program or any derivative work under copyright law:<br> |
| 90 | that is to say, a work containing the Program or a portion of it,<br> |
| 91 | either verbatim or with modifications and/or translated into another<br> |
| 92 | language. (Hereinafter, translation is included without limitation in<br> |
| 93 | the term "modification".) Each licensee is addressed as "you".<br> |
| 94 | <br> |
| 95 | Activities other than copying, distribution and modification are not<br> |
| 96 | covered by this License; they are outside its scope. The act of<br> |
| 97 | running the Program is not restricted, and the output from the Program<br> |
| 98 | is covered only if its contents constitute a work based on the<br> |
| 99 | Program (independent of having been made by running the Program).<br> |
| 100 | Whether that is true depends on what the Program does.<br> |
| 101 | <br> |
| 102 | 1. You may copy and distribute verbatim copies of the Program's<br> |
| 103 | source code as you receive it, in any medium, provided that you<br> |
| 104 | conspicuously and appropriately publish on each copy an appropriate<br> |
| 105 | copyright notice and disclaimer of warranty; keep intact all the<br> |
| 106 | notices that refer to this License and to the absence of any warranty;<br> |
| 107 | and give any other recipients of the Program a copy of this License<br> |
| 108 | along with the Program.<br> |
| 109 | <br> |
| 110 | You may charge a fee for the physical act of transferring a copy, and<br> |
| 111 | you may at your option offer warranty protection in exchange for a fee.<br> |
| 112 | <br> |
| 113 | 2. You may modify your copy or copies of the Program or any portion<br> |
| 114 | of it, thus forming a work based on the Program, and copy and<br> |
| 115 | distribute such modifications or work under the terms of Section 1<br> |
| 116 | above, provided that you also meet all of these conditions:<br> |
| 117 | <br> |
| 118 | a) You must cause the modified files to carry prominent notices<br> |
| 119 | stating that you changed the files and the date of any change.<br> |
| 120 | <br> |
| 121 | b) You must cause any work that you distribute or publish, that in<br> |
| 122 | whole or in part contains or is derived from the Program or any<br> |
| 123 | part thereof, to be licensed as a whole at no charge to all third<br> |
| 124 | parties under the terms of this License.<br> |
| 125 | <br> |
| 126 | c) If the modified program normally reads commands interactively<br> |
| 127 | when run, you must cause it, when started running for such<br> |
| 128 | interactive use in the most ordinary way, to print or display an<br> |
| 129 | announcement including an appropriate copyright notice and a<br> |
| 130 | notice that there is no warranty (or else, saying that you provide<br> |
| 131 | a warranty) and that users may redistribute the program under<br> |
| 132 | these conditions, and telling the user how to view a copy of this<br> |
| 133 | License. (Exception: if the Program itself is interactive but<br> |
| 134 | does not normally print such an announcement, your work based on<br> |
| 135 | the Program is not required to print an announcement.)<br> |
| 136 | <br> |
| 137 | These requirements apply to the modified work as a whole. If<br> |
| 138 | identifiable sections of that work are not derived from the Program,<br> |
| 139 | and can be reasonably considered independent and separate works in<br> |
| 140 | themselves, then this License, and its terms, do not apply to those<br> |
| 141 | sections when you distribute them as separate works. But when you<br> |
| 142 | distribute the same sections as part of a whole which is a work based<br> |
| 143 | on the Program, the distribution of the whole must be on the terms of<br> |
| 144 | this License, whose permissions for other licensees extend to the<br> |
| 145 | entire whole, and thus to each and every part regardless of who wrote it.<br> |
| 146 | <br> |
| 147 | Thus, it is not the intent of this section to claim rights or contest<br> |
| 148 | your rights to work written entirely by you; rather, the intent is to<br> |
| 149 | exercise the right to control the distribution of derivative or<br> |
| 150 | collective works based on the Program.<br> |
| 151 | <br> |
| 152 | In addition, mere aggregation of another work not based on the Program<br> |
| 153 | with the Program (or with a work based on the Program) on a volume of<br> |
| 154 | a storage or distribution medium does not bring the other work under<br> |
| 155 | the scope of this License.<br> |
| 156 | <br> |
| 157 | 3. You may copy and distribute the Program (or a work based on it,<br> |
| 158 | under Section 2) in object code or executable form under the terms of<br> |
| 159 | Sections 1 and 2 above provided that you also do one of the following:<br> |
| 160 | <br> |
| 161 | a) Accompany it with the complete corresponding machine-readable<br> |
| 162 | source code, which must be distributed under the terms of Sections<br> |
| 163 | 1 and 2 above on a medium customarily used for software interchange; or,<br> |
| 164 | <br> |
| 165 | b) Accompany it with a written offer, valid for at least three<br> |
| 166 | years, to give any third party, for a charge no more than your<br> |
| 167 | cost of physically performing source distribution, a complete<br> |
| 168 | machine-readable copy of the corresponding source code, to be<br> |
| 169 | distributed under the terms of Sections 1 and 2 above on a medium<br> |
| 170 | customarily used for software interchange; or,<br> |
| 171 | <br> |
| 172 | c) Accompany it with the information you received as to the offer<br> |
| 173 | to distribute corresponding source code. (This alternative is<br> |
| 174 | allowed only for noncommercial distribution and only if you<br> |
| 175 | received the program in object code or executable form with such<br> |
| 176 | an offer, in accord with Subsection b above.)<br> |
| 177 | <br> |
| 178 | The source code for a work means the preferred form of the work for<br> |
| 179 | making modifications to it. For an executable work, complete source<br> |
| 180 | code means all the source code for all modules it contains, plus any<br> |
| 181 | associated interface definition files, plus the scripts used to<br> |
| 182 | control compilation and installation of the executable. However, as a<br> |
| 183 | special exception, the source code distributed need not include<br> |
| 184 | anything that is normally distributed (in either source or binary<br> |
| 185 | form) with the major components (compiler, kernel, and so on) of the<br> |
| 186 | operating system on which the executable runs, unless that component<br> |
| 187 | itself accompanies the executable.<br> |
| 188 | <br> |
| 189 | If distribution of executable or object code is made by offering<br> |
| 190 | access to copy from a designated place, then offering equivalent<br> |
| 191 | access to copy the source code from the same place counts as<br> |
| 192 | distribution of the source code, even though third parties are not<br> |
| 193 | compelled to copy the source along with the object code.<br> |
| 194 | <br> |
| 195 | 4. You may not copy, modify, sublicense, or distribute the Program<br> |
| 196 | except as expressly provided under this License. Any attempt<br> |
| 197 | otherwise to copy, modify, sublicense or distribute the Program is<br> |
| 198 | void, and will automatically terminate your rights under this License.<br> |
| 199 | However, parties who have received copies, or rights, from you under<br> |
| 200 | this License will not have their licenses terminated so long as such<br> |
| 201 | parties remain in full compliance.<br> |
| 202 | <br> |
| 203 | 5. You are not required to accept this License, since you have not<br> |
| 204 | signed it. However, nothing else grants you permission to modify or<br> |
| 205 | distribute the Program or its derivative works. These actions are<br> |
| 206 | prohibited by law if you do not accept this License. Therefore, by<br> |
| 207 | modifying or distributing the Program (or any work based on the<br> |
| 208 | Program), you indicate your acceptance of this License to do so, and<br> |
| 209 | all its terms and conditions for copying, distributing or modifying<br> |
| 210 | the Program or works based on it.<br> |
| 211 | <br> |
| 212 | 6. Each time you redistribute the Program (or any work based on the<br> |
| 213 | Program), the recipient automatically receives a license from the<br> |
| 214 | original licensor to copy, distribute or modify the Program subject to<br> |
| 215 | these terms and conditions. You may not impose any further<br> |
| 216 | restrictions on the recipients' exercise of the rights granted herein.<br> |
| 217 | You are not responsible for enforcing compliance by third parties to<br> |
| 218 | this License.<br> |
| 219 | <br> |
| 220 | 7. If, as a consequence of a court judgment or allegation of patent<br> |
| 221 | infringement or for any other reason (not limited to patent issues),<br> |
| 222 | conditions are imposed on you (whether by court order, agreement or<br> |
| 223 | otherwise) that contradict the conditions of this License, they do not<br> |
| 224 | excuse you from the conditions of this License. If you cannot<br> |
| 225 | distribute so as to satisfy simultaneously your obligations under this<br> |
| 226 | License and any other pertinent obligations, then as a consequence you<br> |
| 227 | may not distribute the Program at all. For example, if a patent<br> |
| 228 | license would not permit royalty-free redistribution of the Program by<br> |
| 229 | all those who receive copies directly or indirectly through you, then<br> |
| 230 | the only way you could satisfy both it and this License would be to<br> |
| 231 | refrain entirely from distribution of the Program.<br> |
| 232 | <br> |
| 233 | If any portion of this section is held invalid or unenforceable under<br> |
| 234 | any particular circumstance, the balance of the section is intended to<br> |
| 235 | apply and the section as a whole is intended to apply in other<br> |
| 236 | circumstances.<br> |
| 237 | <br> |
| 238 | It is not the purpose of this section to induce you to infringe any<br> |
| 239 | patents or other property right claims or to contest validity of any<br> |
| 240 | such claims; this section has the sole purpose of protecting the<br> |
| 241 | integrity of the free software distribution system, which is<br> |
| 242 | implemented by public license practices. Many people have made<br> |
| 243 | generous contributions to the wide range of software distributed<br> |
| 244 | through that system in reliance on consistent application of that<br> |
| 245 | system; it is up to the author/donor to decide if he or she is willing<br> |
| 246 | to distribute software through any other system and a licensee cannot<br> |
| 247 | impose that choice.<br> |
| 248 | <br> |
| 249 | This section is intended to make thoroughly clear what is believed to<br> |
| 250 | be a consequence of the rest of this License.<br> |
| 251 | <br> |
| 252 | 8. If the distribution and/or use of the Program is restricted in<br> |
| 253 | certain countries either by patents or by copyrighted interfaces, the<br> |
| 254 | original copyright holder who places the Program under this License<br> |
| 255 | may add an explicit geographical distribution limitation excluding<br> |
| 256 | those countries, so that distribution is permitted only in or among<br> |
| 257 | countries not thus excluded. In such case, this License incorporates<br> |
| 258 | the limitation as if written in the body of this License.<br> |
| 259 | <br> |
| 260 | 9. The Free Software Foundation may publish revised and/or new versions<br> |
| 261 | of the General Public License from time to time. Such new versions will<br> |
| 262 | be similar in spirit to the present version, but may differ in detail to<br> |
| 263 | address new problems or concerns.<br> |
| 264 | <br> |
| 265 | Each version is given a distinguishing version number. If the Program<br> |
| 266 | specifies a version number of this License which applies to it and "any<br> |
| 267 | later version", you have the option of following the terms and conditions<br> |
| 268 | either of that version or of any later version published by the Free<br> |
| 269 | Software Foundation. If the Program does not specify a version number of<br> |
| 270 | this License, you may choose any version ever published by the Free Software<br> |
| 271 | Foundation.<br> |
| 272 | <br> |
| 273 | 10. If you wish to incorporate parts of the Program into other free<br> |
| 274 | programs whose distribution conditions are different, write to the author<br> |
| 275 | to ask for permission. For software which is copyrighted by the Free<br> |
| 276 | Software Foundation, write to the Free Software Foundation; we sometimes<br> |
| 277 | make exceptions for this. Our decision will be guided by the two goals<br> |
| 278 | of preserving the free status of all derivatives of our free software and<br> |
| 279 | of promoting the sharing and reuse of software generally.<br> |
| 280 | <br> |
| 281 | NO WARRANTY<br> |
| 282 | <br> |
| 283 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY<br> |
| 284 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN<br> |
| 285 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES<br> |
| 286 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED<br> |
| 287 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF<br> |
| 288 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS<br> |
| 289 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE<br> |
| 290 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,<br> |
| 291 | REPAIR OR CORRECTION.<br> |
| 292 | <br> |
| 293 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING<br> |
| 294 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR<br> |
| 295 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,<br> |
| 296 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING<br> |
| 297 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED<br> |
| 298 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY<br> |
| 299 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER<br> |
| 300 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE<br> |
| 301 | POSSIBILITY OF SUCH DAMAGES.<br> |
| 302 | <br> |
| 303 | END OF TERMS AND CONDITIONS<br> |
| 304 | <br> |
| 305 | How to Apply These Terms to Your New Programs<br> |
| 306 | <br> |
| 307 | If you develop a new program, and you want it to be of the greatest<br> |
| 308 | possible use to the public, the best way to achieve this is to make it<br> |
| 309 | free software which everyone can redistribute and change under these terms.<br> |
| 310 | <br> |
| 311 | To do so, attach the following notices to the program. It is safest<br> |
| 312 | to attach them to the start of each source file to most effectively<br> |
| 313 | convey the exclusion of warranty; and each file should have at least<br> |
| 314 | the "copyright" line and a pointer to where the full notice is found.<br> |
| 315 | <br> |
| 316 | <one line to give the program's name and a brief idea of what it does.><br> |
| 317 | Copyright (C) <year> <name of author><br> |
| 318 | <br> |
| 319 | This program is free software; you can redistribute it and/or modify<br> |
| 320 | it under the terms of the GNU General Public License as published by<br> |
| 321 | the Free Software Foundation; either version 2 of the License, or<br> |
| 322 | (at your option) any later version.<br> |
| 323 | <br> |
| 324 | This program is distributed in the hope that it will be useful,<br> |
| 325 | but WITHOUT ANY WARRANTY; without even the implied warranty of<br> |
| 326 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the<br> |
| 327 | GNU General Public License for more details.<br> |
| 328 | <br> |
| 329 | You should have received a copy of the GNU General Public License along<br> |
| 330 | with this program; if not, write to the Free Software Foundation, Inc.,<br> |
| 331 | 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.<br> |
| 332 | <br> |
| 333 | Also add information on how to contact you by electronic and paper mail.<br> |
| 334 | <br> |
| 335 | If the program is interactive, make it output a short notice like this<br> |
| 336 | when it starts in an interactive mode:<br> |
| 337 | <br> |
| 338 | Gnomovision version 69, Copyright (C) year name of author<br> |
| 339 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.<br> |
| 340 | This is free software, and you are welcome to redistribute it<br> |
| 341 | under certain conditions; type `show c' for details.<br> |
| 342 | <br> |
| 343 | The hypothetical commands `show w' and `show c' should show the appropriate<br> |
| 344 | parts of the General Public License. Of course, the commands you use may<br> |
| 345 | be called something other than `show w' and `show c'; they could even be<br> |
| 346 | mouse-clicks or menu items--whatever suits your program.<br> |
| 347 | <br> |
| 348 | You should also get your employer (if you work as a programmer) or your<br> |
| 349 | school, if any, to sign a "copyright disclaimer" for the program, if<br> |
| 350 | necessary. Here is a sample; alter the names:<br> |
| 351 | <br> |
| 352 | Yoyodyne, Inc., hereby disclaims all copyright interest in the program<br> |
| 353 | `Gnomovision' (which makes passes at compilers) written by James Hacker.<br> |
| 354 | <br> |
| 355 | <signature of Ty Coon>, 1 April 1989<br> |
| 356 | Ty Coon, President of Vice<br> |
| 357 | <br> |
| 358 | This General Public License does not permit incorporating your program into<br> |
