By contrast, the GNU General Public 107License is intended to guarantee your freedom to share and change free 108software--to make sure the software is free for all its users. This 109General Public License applies to most of the Free Software 110Foundation's software and to any other program whose authors commit to 111using it. (Some other Free Software Foundation software is covered by 112the GNU Library General Public License instead.) You can apply it to 113your programs, too. 114 115 When we speak of free software, we are referring to freedom, not 116price. Our General Public Licenses are designed to make sure that you 117have the freedom to distribute copies of free software (and charge for 118this service if you wish), that you receive source code or can get it 119if you want it, that you can change the software or use pieces of it 120in new free programs; and that you know you can do these things. 121 122 To protect your rights, we need to make restrictions that forbid 123anyone to deny you these rights or to ask you to surrender the rights. 124These restrictions translate to certain responsibilities for you if you 125distribute copies of the software, or if you modify it. 126 127 For example, if you distribute copies of such a program, whether 128gratis or for a fee, you must give the recipients all the rights that 129you have. You must make sure that they, too, receive or can get the 130source code. And you must show them these terms so they know their 131rights. 132 133 We protect your rights with two steps: (1) copyright the software, and 134(2) offer you this license which gives you legal permission to copy, 135distribute and/or modify the software. 136 137 Also, for each author's protection and ours, we want to make certain 138that everyone understands that there is no warranty for this free 139software. If the software is modified by someone else and passed on, we 140want its recipients to know that what they have is not the original, so 141that any problems introduced by others will not reflect on the original 142authors' reputations. 143 144 Finally, any free program is threatened constantly by software 145patents. We wish to avoid the danger that redistributors of a free 146program will individually obtain patent licenses, in effect making the 147program proprietary. To prevent this, we have made it clear that any 148patent must be licensed for everyone's free use or not licensed at all. 149 150 The precise terms and conditions for copying, distribution and 151modification follow. 152 153 GNU GENERAL PUBLIC LICENSE 154 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 155 156 0. This License applies to any program or other work which contains 157a notice placed by the copyright holder saying it may be distributed 158under the terms of this General Public License. The "Program", below, 159refers to any such program or work, and a "work based on the Program" 160means either the Program or any derivative work under copyright law: 161that is to say, a work containing the Program or a portion of it, 162either verbatim or with modifications and/or translated into another 163language. (Hereinafter, translation is included without limitation in 164the term "modification".) Each licensee is addressed as "you". 165 166Activities other than copying, distribution and modification are not 167covered by this License; they are outside its scope. The act of 168running the Program is not restricted, and the output from the Program 169is covered only if its contents constitute a work based on the 170Program (independent of having been made by running the Program). 171Whether that is true depends on what the Program does. 172 173 1. You may copy and distribute verbatim copies of the Program's 174source code as you receive it, in any medium, provided that you 175conspicuously and appropriately publish on each copy an appropriate 176copyright notice and disclaimer of warranty; keep intact all the 177notices that refer to this License and to the absence of any warranty; 178and give any other recipients of the Program a copy of this License 179along with the Program. 180 181You may charge a fee for the physical act of transferring a copy, and 182you may at your option offer warranty protection in exchange for a fee. 183 184 2. You may modify your copy or copies of the Program or any portion 185of it, thus forming a work based on the Program, and copy and 186distribute such modifications or work under the terms of Section 1 187above, provided that you also meet all of these conditions: 188 189 a) You must cause the modified files to carry prominent notices 190 stating that you changed the files and the date of any change. 191 192 b) You must cause any work that you distribute or publish, that in 193 whole or in part contains or is derived from the Program or any 194 part thereof, to be licensed as a whole at no charge to all third 195 parties under the terms of this License. 196 197 c) If the modified program normally reads commands interactively 198 when run, you must cause it, when started running for such 199 interactive use in the most ordinary way, to print or display an 200 announcement including an appropriate copyright notice and a 201 notice that there is no warranty (or else, saying that you provide 202 a warranty) and that users may redistribute the program under 203 these conditions, and telling the user how to view a copy of this 204 License. (Exception: if the Program itself is interactive but 205 does not normally print such an announcement, your work based on 206 the Program is not required to print an announcement.) 207 208These requirements apply to the modified work as a whole. If 209identifiable sections of that work are not derived from the Program, 210and can be reasonably considered independent and separate works in 211themselves, then this License, and its terms, do not apply to those 212sections when you distribute them as separate works. But when you 213distribute the same sections as part of a whole which is a work based 214on the Program, the distribution of the whole must be on the terms of 215this License, whose permissions for other licensees extend to the 216entire whole, and thus to each and every part regardless of who wrote it. 217 218Thus, it is not the intent of this section to claim rights or contest 219your rights to work written entirely by you; rather, the intent is to 220exercise the right to control the distribution of derivative or 221collective works based on the Program. 222 223In addition, mere aggregation of another work not based on the Program 224with the Program (or with a work based on the Program) on a volume of 225a storage or distribution medium does not bring the other work under 226the scope of this License. 227 228 3. You may copy and distribute the Program (or a work based on it, 229under Section 2) in object code or executable form under the terms of 230Sections 1 and 2 above provided that you also do one of the following: 231 232 a) Accompany it with the complete corresponding machine-readable 233 source code, which must be distributed under the terms of Sections 234 1 and 2 above on a medium customarily used for software interchange; or, 235 236 b) Accompany it with a written offer, valid for at least three 237 years, to give any third party, for a charge no more than your 238 cost of physically performing source distribution, a complete 239 machine-readable copy of the corresponding source code, to be 240 distributed under the terms of Sections 1 and 2 above on a medium 241 customarily used for software interchange; or, 242 243 c) Accompany it with the information you received as to the offer 244 to distribute corresponding source code. (This alternative is 245 allowed only for noncommercial distribution and only if you 246 received the program in object code or executable form with such 247 an offer, in accord with Subsection b above.) 248 249The source code for a work means the preferred form of the work for 250making modifications to it. For an executable work, complete source 251code means all the source code for all modules it contains, plus any 252associated interface definition files, plus the scripts used to 253control compilation and installation of the executable. However, as a 254special exception, the source code distributed need not include 255anything that is normally distributed (in either source or binary 256form) with the major components (compiler, kernel, and so on) of the 257operating system on which the executable runs, unless that component 258itself accompanies the executable. 259 260If distribution of executable or object code is made by offering 261access to copy from a designated place, then offering equivalent 262access to copy the source code from the same place counts as 263distribution of the source code, even though third parties are not 264compelled to copy the source along with the object code. 265 266 4. You may not copy, modify, sublicense, or distribute the Program 267except as expressly provided under this License. Any attempt 268otherwise to copy, modify, sublicense or distribute the Program is 269void, and will automatically terminate your rights under this License. 270However, parties who have received copies, or rights, from you under 271this License will not have their licenses terminated so long as such 272parties remain in full compliance. 273 274 5. You are not required to accept this License, since you have not 275signed it. However, nothing else grants you permission to modify or 276distribute the Program or its derivative works. These actions are 277prohibited by law if you do not accept this License. Therefore, by 278modifying or distributing the Program (or any work based on the 279Program), you indicate your acceptance of this License to do so, and 280all its terms and conditions for copying, distributing or modifying 281the Program or works based on it. 282 283 6. Each time you redistribute the Program (or any work based on the 284Program), the recipient automatically receives a license from the 285original licensor to copy, distribute or modify the Program subject to 286these terms and conditions. You may not impose any further 287restrictions on the recipients' exercise of the rights granted herein. 288You are not responsible for enforcing compliance by third parties to 289this License. 290 291 7. If, as a consequence of a court judgment or allegation of patent 292infringement or for any other reason (not limited to patent issues), 293conditions are imposed on you (whether by court order, agreement or 294otherwise) that contradict the conditions of this License, they do not 295excuse you from the conditions of this License. If you cannot 296distribute so as to satisfy simultaneously your obligations under this 297License and any other pertinent obligations, then as a consequence you 298may not distribute the Program at all. For example, if a patent 299license would not permit royalty-free redistribution of the Program by 300all those who receive copies directly or indirectly through you, then 301the only way you could satisfy both it and this License would be to 302refrain entirely from distribution of the Program. 303 304If any portion of this section is held invalid or unenforceable under 305any particular circumstance, the balance of the section is intended to 306apply and the section as a whole is intended to apply in other 307circumstances. 308 309It is not the purpose of this section to induce you to infringe any 310patents or other property right claims or to contest validity of any 311such claims; this section has the sole purpose of protecting the 312integrity of the free software distribution system, which is 313implemented by public license practices. Many people have made 314generous contributions to the wide range of software distributed 315through that system in reliance on consistent application of that 316system; it is up to the author/donor to decide if he or she is willing 317to distribute software through any other system and a licensee cannot 318impose that choice. 319 320This section is intended to make thoroughly clear what is believed to 321be a consequence of the rest of this License. 322 323 8. If the distribution and/or use of the Program is restricted in 324certain countries either by patents or by copyrighted interfaces, the 325original copyright holder who places the Program under this License 326may add an explicit geographical distribution limitation excluding 327those countries, so that distribution is permitted only in or among 328countries not thus excluded. In such case, this License incorporates 329the limitation as if written in the body of this License. 330 331 9. The Free Software Foundation may publish revised and/or new versions 332of the General Public License from time to time. Such new versions will 333be similar in spirit to the present version, but may differ in detail to 334address new problems or concerns. 335 336Each version is given a distinguishing version number. If the Program 337specifies a version number of this License which applies to it and "any 338later version", you have the option of following the terms and conditions 339either of that version or of any later version published by the Free 340Software Foundation. If the Program does not specify a version number of 341this License, you may choose any version ever published by the Free Software 342Foundation. 343 344 10. If you wish to incorporate parts of the Program into other free 345programs whose distribution conditions are different, write to the author 346to ask for permission. For software which is copyrighted by the Free 347Software Foundation, write to the Free Software Foundation; we sometimes 348make exceptions for this. Our decision will be guided by the two goals 349of preserving the free status of all derivatives of our free software and 350of promoting the sharing and reuse of software generally. 351 352 NO WARRANTY 353 354 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 355FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 356OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 357PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 358OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 359MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 360TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 361PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 362REPAIR OR CORRECTION. 363 364 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 365WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 366REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 367INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 368OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 369TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 370YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 371PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 372POSSIBILITY OF SUCH DAMAGES. 373 374 END OF TERMS AND CONDITIONS 375 376 How to Apply These Terms to Your New Programs 377 378 If you develop a new program, and you want it to be of the greatest 379possible use to the public, the best way to achieve this is to make it 380free software which everyone can redistribute and change under these terms. 381 382 To do so, attach the following notices to the program. It is safest 383to attach them to the start of each source file to most effectively 384convey the exclusion of warranty; and each file should have at least 385the "copyright" line and a pointer to where the full notice is found. 386 387 <one line to give the program's name and a brief idea of what it does.> 388 Copyright (C) <year> <name of author> 389 390 This program is free software; you can redistribute it and/or modify 391 it under the terms of the GNU General Public License as published by 392 the Free Software Foundation; either version 2 of the License, or 393 (at your option) any later version. 394 395 This program is distributed in the hope that it will be useful, 396 but WITHOUT ANY WARRANTY; without even the implied warranty of 397 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 398 GNU General Public License for more details. 399 400 You should have received a copy of the GNU General Public License 401 along with this program; if not, write to the Free Software 402 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 403 404 405Also add information on how to contact you by electronic and paper mail. 406 407If the program is interactive, make it output a short notice like this 408when it starts in an interactive mode: 409 410 Gnomovision version 69, Copyright (C) year name of author 411 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 412 This is free software, and you are welcome to redistribute it 413 under certain conditions; type `show c' for details. 414 415The hypothetical commands `show w' and `show c' should show the appropriate 416parts of the General Public License. Of course, the commands you use may 417be called something other than `show w' and `show c'; they could even be 418mouse-clicks or menu items--whatever suits your program. 419 420You should also get your employer (if you work as a programmer) or your 421school, if any, to sign a "copyright disclaimer" for the program, if 422necessary. Here is a sample; alter the names: 423 424 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 425 `Gnomovision' (which makes passes at compilers) written by James Hacker. 426 427 <signature of Ty Coon>, 1 April 1989 428 Ty Coon, President of Vice 429 430This General Public License does not permit incorporating your program into 431proprietary programs. If your program is a subroutine library, you may 432consider it more useful to permit linking proprietary applications with the 433library. If this is what you want to do, use the GNU Library General 434Public License instead of this License. 435
