| | 45 | The GNU GENERAL PUBLIC LICENCE is: |
|---|
| | 46 | |
|---|
| | 47 | GNU GENERAL PUBLIC LICENSE |
|---|
| | 48 | Version 2, June 1991 |
|---|
| | 49 | |
|---|
| | 50 | Copyright (C) 1989, 1991 Free Software Foundation, Inc., |
|---|
| | 51 | 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA |
|---|
| | 52 | Everyone is permitted to copy and distribute verbatim copies |
|---|
| | 53 | of this license document, but changing it is not allowed. |
|---|
| | 54 | |
|---|
| | 55 | Preamble |
|---|
| | 56 | |
|---|
| | 57 | The licenses for most software are designed to take away your |
|---|
| | 58 | freedom to share and change it. By contrast, the GNU General Public |
|---|
| | 59 | License is intended to guarantee your freedom to share and change free |
|---|
| | 60 | software--to make sure the software is free for all its users. This |
|---|
| | 61 | General Public License applies to most of the Free Software |
|---|
| | 62 | Foundation's software and to any other program whose authors commit to |
|---|
| | 63 | using it. (Some other Free Software Foundation software is covered by |
|---|
| | 64 | the GNU Lesser General Public License instead.) You can apply it to |
|---|
| | 65 | your programs, too. |
|---|
| | 66 | |
|---|
| | 67 | When we speak of free software, we are referring to freedom, not |
|---|
| | 68 | price. Our General Public Licenses are designed to make sure that you |
|---|
| | 69 | have the freedom to distribute copies of free software (and charge for |
|---|
| | 70 | this service if you wish), that you receive source code or can get it |
|---|
| | 71 | if you want it, that you can change the software or use pieces of it |
|---|
| | 72 | in new free programs; and that you know you can do these things. |
|---|
| | 73 | |
|---|
| | 74 | To protect your rights, we need to make restrictions that forbid |
|---|
| | 75 | anyone to deny you these rights or to ask you to surrender the rights. |
|---|
| | 76 | These restrictions translate to certain responsibilities for you if you |
|---|
| | 77 | distribute copies of the software, or if you modify it. |
|---|
| | 78 | |
|---|
| | 79 | For example, if you distribute copies of such a program, whether |
|---|
| | 80 | gratis or for a fee, you must give the recipients all the rights that |
|---|
| | 81 | you have. You must make sure that they, too, receive or can get the |
|---|
| | 82 | source code. And you must show them these terms so they know their |
|---|
| | 83 | rights. |
|---|
| | 84 | |
|---|
| | 85 | We protect your rights with two steps: (1) copyright the software, and |
|---|
| | 86 | (2) offer you this license which gives you legal permission to copy, |
|---|
| | 87 | distribute and/or modify the software. |
|---|
| | 88 | |
|---|
| | 89 | Also, for each author's protection and ours, we want to make certain |
|---|
| | 90 | that everyone understands that there is no warranty for this free |
|---|
| | 91 | software. If the software is modified by someone else and passed on, we |
|---|
| | 92 | want its recipients to know that what they have is not the original, so |
|---|
| | 93 | that any problems introduced by others will not reflect on the original |
|---|
| | 94 | authors' reputations. |
|---|
| | 95 | |
|---|
| | 96 | Finally, any free program is threatened constantly by software |
|---|
| | 97 | patents. We wish to avoid the danger that redistributors of a free |
|---|
| | 98 | program will individually obtain patent licenses, in effect making the |
|---|
| | 99 | program proprietary. To prevent this, we have made it clear that any |
|---|
| | 100 | patent must be licensed for everyone's free use or not licensed at all. |
|---|
| | 101 | |
|---|
| | 102 | The precise terms and conditions for copying, distribution and |
|---|
| | 103 | modification follow. |
|---|
| | 104 | |
|---|
| | 105 | GNU GENERAL PUBLIC LICENSE |
|---|
| | 106 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
|---|
| | 107 | |
|---|
| | 108 | 0. This License applies to any program or other work which contains |
|---|
| | 109 | a notice placed by the copyright holder saying it may be distributed |
|---|
| | 110 | under the terms of this General Public License. The "Program", below, |
|---|
| | 111 | refers to any such program or work, and a "work based on the Program" |
|---|
| | 112 | means either the Program or any derivative work under copyright law: |
|---|
| | 113 | that is to say, a work containing the Program or a portion of it, |
|---|
| | 114 | either verbatim or with modifications and/or translated into another |
|---|
| | 115 | language. (Hereinafter, translation is included without limitation in |
|---|
| | 116 | the term "modification".) Each licensee is addressed as "you". |
|---|
| | 117 | |
|---|
| | 118 | Activities other than copying, distribution and modification are not |
|---|
| | 119 | covered by this License; they are outside its scope. The act of |
|---|
| | 120 | running the Program is not restricted, and the output from the Program |
|---|
| | 121 | is covered only if its contents constitute a work based on the |
|---|
| | 122 | Program (independent of having been made by running the Program). |
|---|
| | 123 | Whether that is true depends on what the Program does. |
|---|
| | 124 | |
|---|
| | 125 | 1. You may copy and distribute verbatim copies of the Program's |
|---|
| | 126 | source code as you receive it, in any medium, provided that you |
|---|
| | 127 | conspicuously and appropriately publish on each copy an appropriate |
|---|
| | 128 | copyright notice and disclaimer of warranty; keep intact all the |
|---|
| | 129 | notices that refer to this License and to the absence of any warranty; |
|---|
| | 130 | and give any other recipients of the Program a copy of this License |
|---|
| | 131 | along with the Program. |
|---|
| | 132 | |
|---|
| | 133 | You may charge a fee for the physical act of transferring a copy, and |
|---|
| | 134 | you may at your option offer warranty protection in exchange for a fee. |
|---|
| | 135 | |
|---|
| | 136 | 2. You may modify your copy or copies of the Program or any portion |
|---|
| | 137 | of it, thus forming a work based on the Program, and copy and |
|---|
| | 138 | distribute such modifications or work under the terms of Section 1 |
|---|
| | 139 | above, provided that you also meet all of these conditions: |
|---|
| | 140 | |
|---|
| | 141 | a) You must cause the modified files to carry prominent notices |
|---|
| | 142 | stating that you changed the files and the date of any change. |
|---|
| | 143 | |
|---|
| | 144 | b) You must cause any work that you distribute or publish, that in |
|---|
| | 145 | whole or in part contains or is derived from the Program or any |
|---|
| | 146 | part thereof, to be licensed as a whole at no charge to all third |
|---|
| | 147 | parties under the terms of this License. |
|---|
| | 148 | |
|---|
| | 149 | c) If the modified program normally reads commands interactively |
|---|
| | 150 | when run, you must cause it, when started running for such |
|---|
| | 151 | interactive use in the most ordinary way, to print or display an |
|---|
| | 152 | announcement including an appropriate copyright notice and a |
|---|
| | 153 | notice that there is no warranty (or else, saying that you provide |
|---|
| | 154 | a warranty) and that users may redistribute the program under |
|---|
| | 155 | these conditions, and telling the user how to view a copy of this |
|---|
| | 156 | License. (Exception: if the Program itself is interactive but |
|---|
| | 157 | does not normally print such an announcement, your work based on |
|---|
| | 158 | the Program is not required to print an announcement.) |
|---|
| | 159 | |
|---|
| | 160 | These requirements apply to the modified work as a whole. If |
|---|
| | 161 | identifiable sections of that work are not derived from the Program, |
|---|
| | 162 | and can be reasonably considered independent and separate works in |
|---|
| | 163 | themselves, then this License, and its terms, do not apply to those |
|---|
| | 164 | sections when you distribute them as separate works. But when you |
|---|
| | 165 | distribute the same sections as part of a whole which is a work based |
|---|
| | 166 | on the Program, the distribution of the whole must be on the terms of |
|---|
| | 167 | this License, whose permissions for other licensees extend to the |
|---|
| | 168 | entire whole, and thus to each and every part regardless of who wrote it. |
|---|
| | 169 | |
|---|
| | 170 | Thus, it is not the intent of this section to claim rights or contest |
|---|
| | 171 | your rights to work written entirely by you; rather, the intent is to |
|---|
| | 172 | exercise the right to control the distribution of derivative or |
|---|
| | 173 | collective works based on the Program. |
|---|
| | 174 | |
|---|
| | 175 | In addition, mere aggregation of another work not based on the Program |
|---|
| | 176 | with the Program (or with a work based on the Program) on a volume of |
|---|
| | 177 | a storage or distribution medium does not bring the other work under |
|---|
| | 178 | the scope of this License. |
|---|
| | 179 | |
|---|
| | 180 | 3. You may copy and distribute the Program (or a work based on it, |
|---|
| | 181 | under Section 2) in object code or executable form under the terms of |
|---|
| | 182 | Sections 1 and 2 above provided that you also do one of the following: |
|---|
| | 183 | |
|---|
| | 184 | a) Accompany it with the complete corresponding machine-readable |
|---|
| | 185 | source code, which must be distributed under the terms of Sections |
|---|
| | 186 | 1 and 2 above on a medium customarily used for software interchange; or, |
|---|
| | 187 | |
|---|
| | 188 | b) Accompany it with a written offer, valid for at least three |
|---|
| | 189 | years, to give any third party, for a charge no more than your |
|---|
| | 190 | cost of physically performing source distribution, a complete |
|---|
| | 191 | machine-readable copy of the corresponding source code, to be |
|---|
| | 192 | distributed under the terms of Sections 1 and 2 above on a medium |
|---|
| | 193 | customarily used for software interchange; or, |
|---|
| | 194 | |
|---|
| | 195 | c) Accompany it with the information you received as to the offer |
|---|
| | 196 | to distribute corresponding source code. (This alternative is |
|---|
| | 197 | allowed only for noncommercial distribution and only if you |
|---|
| | 198 | received the program in object code or executable form with such |
|---|
| | 199 | an offer, in accord with Subsection b above.) |
|---|
| | 200 | |
|---|
| | 201 | The source code for a work means the preferred form of the work for |
|---|
| | 202 | making modifications to it. For an executable work, complete source |
|---|
| | 203 | code means all the source code for all modules it contains, plus any |
|---|
| | 204 | associated interface definition files, plus the scripts used to |
|---|
| | 205 | control compilation and installation of the executable. However, as a |
|---|
| | 206 | special exception, the source code distributed need not include |
|---|
| | 207 | anything that is normally distributed (in either source or binary |
|---|
| | 208 | form) with the major components (compiler, kernel, and so on) of the |
|---|
| | 209 | operating system on which the executable runs, unless that component |
|---|
| | 210 | itself accompanies the executable. |
|---|
| | 211 | |
|---|
| | 212 | If distribution of executable or object code is made by offering |
|---|
| | 213 | access to copy from a designated place, then offering equivalent |
|---|
| | 214 | access to copy the source code from the same place counts as |
|---|
| | 215 | distribution of the source code, even though third parties are not |
|---|
| | 216 | compelled to copy the source along with the object code. |
|---|
| | 217 | |
|---|
| | 218 | 4. You may not copy, modify, sublicense, or distribute the Program |
|---|
| | 219 | except as expressly provided under this License. Any attempt |
|---|
| | 220 | otherwise to copy, modify, sublicense or distribute the Program is |
|---|
| | 221 | void, and will automatically terminate your rights under this License. |
|---|
| | 222 | However, parties who have received copies, or rights, from you under |
|---|
| | 223 | this License will not have their licenses terminated so long as such |
|---|
| | 224 | parties remain in full compliance. |
|---|
| | 225 | |
|---|
| | 226 | 5. You are not required to accept this License, since you have not |
|---|
| | 227 | signed it. However, nothing else grants you permission to modify or |
|---|
| | 228 | distribute the Program or its derivative works. These actions are |
|---|
| | 229 | prohibited by law if you do not accept this License. Therefore, by |
|---|
| | 230 | modifying or distributing the Program (or any work based on the |
|---|
| | 231 | Program), you indicate your acceptance of this License to do so, and |
|---|
| | 232 | all its terms and conditions for copying, distributing or modifying |
|---|
| | 233 | the Program or works based on it. |
|---|
| | 234 | |
|---|
| | 235 | 6. Each time you redistribute the Program (or any work based on the |
|---|
| | 236 | Program), the recipient automatically receives a license from the |
|---|
| | 237 | original licensor to copy, distribute or modify the Program subject to |
|---|
| | 238 | these terms and conditions. You may not impose any further |
|---|
| | 239 | restrictions on the recipients' exercise of the rights granted herein. |
|---|
| | 240 | You are not responsible for enforcing compliance by third parties to |
|---|
| | 241 | this License. |
|---|
| | 242 | |
|---|
| | 243 | 7. If, as a consequence of a court judgment or allegation of patent |
|---|
| | 244 | infringement or for any other reason (not limited to patent issues), |
|---|
| | 245 | conditions are imposed on you (whether by court order, agreement or |
|---|
| | 246 | otherwise) that contradict the conditions of this License, they do not |
|---|
| | 247 | excuse you from the conditions of this License. If you cannot |
|---|
| | 248 | distribute so as to satisfy simultaneously your obligations under this |
|---|
| | 249 | License and any other pertinent obligations, then as a consequence you |
|---|
| | 250 | may not distribute the Program at all. For example, if a patent |
|---|
| | 251 | license would not permit royalty-free redistribution of the Program by |
|---|
| | 252 | all those who receive copies directly or indirectly through you, then |
|---|
| | 253 | the only way you could satisfy both it and this License would be to |
|---|
| | 254 | refrain entirely from distribution of the Program. |
|---|
| | 255 | |
|---|
| | 256 | If any portion of this section is held invalid or unenforceable under |
|---|
| | 257 | any particular circumstance, the balance of the section is intended to |
|---|
| | 258 | apply and the section as a whole is intended to apply in other |
|---|
| | 259 | circumstances. |
|---|
| | 260 | |
|---|
| | 261 | It is not the purpose of this section to induce you to infringe any |
|---|
| | 262 | patents or other property right claims or to contest validity of any |
|---|
| | 263 | such claims; this section has the sole purpose of protecting the |
|---|
| | 264 | integrity of the free software distribution system, which is |
|---|
| | 265 | implemented by public license practices. Many people have made |
|---|
| | 266 | generous contributions to the wide range of software distributed |
|---|
| | 267 | through that system in reliance on consistent application of that |
|---|
| | 268 | system; it is up to the author/donor to decide if he or she is willing |
|---|
| | 269 | to distribute software through any other system and a licensee cannot |
|---|
| | 270 | impose that choice. |
|---|
| | 271 | |
|---|
| | 272 | This section is intended to make thoroughly clear what is believed to |
|---|
| | 273 | be a consequence of the rest of this License. |
|---|
| | 274 | |
|---|
| | 275 | 8. If the distribution and/or use of the Program is restricted in |
|---|
| | 276 | certain countries either by patents or by copyrighted interfaces, the |
|---|
| | 277 | original copyright holder who places the Program under this License |
|---|
| | 278 | may add an explicit geographical distribution limitation excluding |
|---|
| | 279 | those countries, so that distribution is permitted only in or among |
|---|
| | 280 | countries not thus excluded. In such case, this License incorporates |
|---|
| | 281 | the limitation as if written in the body of this License. |
|---|
| | 282 | |
|---|
| | 283 | 9. The Free Software Foundation may publish revised and/or new versions |
|---|
| | 284 | of the General Public License from time to time. Such new versions will |
|---|
| | 285 | be similar in spirit to the present version, but may differ in detail to |
|---|
| | 286 | address new problems or concerns. |
|---|
| | 287 | |
|---|
| | 288 | Each version is given a distinguishing version number. If the Program |
|---|
| | 289 | specifies a version number of this License which applies to it and "any |
|---|
| | 290 | later version", you have the option of following the terms and conditions |
|---|
| | 291 | either of that version or of any later version published by the Free |
|---|
| | 292 | Software Foundation. If the Program does not specify a version number of |
|---|
| | 293 | this License, you may choose any version ever published by the Free Software |
|---|
| | 294 | Foundation. |
|---|
| | 295 | |
|---|
| | 296 | 10. If you wish to incorporate parts of the Program into other free |
|---|
| | 297 | programs whose distribution conditions are different, write to the author |
|---|
| | 298 | to ask for permission. For software which is copyrighted by the Free |
|---|
| | 299 | Software Foundation, write to the Free Software Foundation; we sometimes |
|---|
| | 300 | make exceptions for this. Our decision will be guided by the two goals |
|---|
| | 301 | of preserving the free status of all derivatives of our free software and |
|---|
| | 302 | of promoting the sharing and reuse of software generally. |
|---|
| | 303 | |
|---|
| | 304 | NO WARRANTY |
|---|
| | 305 | |
|---|
| | 306 | 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY |
|---|
| | 307 | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN |
|---|
| | 308 | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES |
|---|
| | 309 | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED |
|---|
| | 310 | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
|---|
| | 311 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS |
|---|
| | 312 | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE |
|---|
| | 313 | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, |
|---|
| | 314 | REPAIR OR CORRECTION. |
|---|
| | 315 | |
|---|
| | 316 | 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
|---|
| | 317 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR |
|---|
| | 318 | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, |
|---|
| | 319 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING |
|---|
| | 320 | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED |
|---|
| | 321 | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY |
|---|
| | 322 | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER |
|---|
| | 323 | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE |
|---|
| | 324 | POSSIBILITY OF SUCH DAMAGES. |
|---|
| | 325 | |
|---|
| | 326 | END OF TERMS AND CONDITIONS |
|---|
| | 327 | |
|---|
| | 328 | How to Apply These Terms to Your New Programs |
|---|
| | 329 | |
|---|
| | 330 | If you develop a new program, and you want it to be of the greatest |
|---|
| | 331 | possible use to the public, the best way to achieve this is to make it |
|---|
| | 332 | free software which everyone can redistribute and change under these terms. |
|---|
| | 333 | |
|---|
| | 334 | To do so, attach the following notices to the program. It is safest |
|---|
| | 335 | to attach them to the start of each source file to most effectively |
|---|
| | 336 | convey the exclusion of warranty; and each file should have at least |
|---|
| | 337 | the "copyright" line and a pointer to where the full notice is found. |
|---|
| | 338 | |
|---|
| | 339 | <one line to give the program's name and a brief idea of what it does.> |
|---|
| | 340 | Copyright (C) <year> <name of author> |
|---|
| | 341 | |
|---|
| | 342 | This program is free software; you can redistribute it and/or modify |
|---|
| | 343 | it under the terms of the GNU General Public License as published by |
|---|
| | 344 | the Free Software Foundation; either version 2 of the License, or |
|---|
| | 345 | (at your option) any later version. |
|---|
| | 346 | |
|---|
| | 347 | This program is distributed in the hope that it will be useful, |
|---|
| | 348 | but WITHOUT ANY WARRANTY; without even the implied warranty of |
|---|
| | 349 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
|---|
| | 350 | GNU General Public License for more details. |
|---|
| | 351 | |
|---|
| | 352 | You should have received a copy of the GNU General Public License along |
|---|
| | 353 | with this program; if not, write to the Free Software Foundation, Inc., |
|---|
| | 354 | 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. |
|---|
| | 355 | |
|---|
| | 356 | Also add information on how to contact you by electronic and paper mail. |
|---|
| | 357 | |
|---|
| | 358 | If the program is interactive, make it output a short notice like this |
|---|
| | 359 | when it starts in an interactive mode: |
|---|
| | 360 | |
|---|
| | 361 | Gnomovision version 69, Copyright (C) year name of author |
|---|
| | 362 | Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
|---|
| | 363 | This is free software, and you are welcome to redistribute it |
|---|
| | 364 | under certain conditions; type `show c' for details. |
|---|
| | 365 | |
|---|
| | 366 | The hypothetical commands `show w' and `show c' should show the appropriate |
|---|
| | 367 | parts of the General Public License. Of course, the commands you use may |
|---|
| | 368 | be called something other than `show w' and `show c'; they could even be |
|---|
| | 369 | mouse-clicks or menu items--whatever suits your program. |
|---|
| | 370 | |
|---|
