By contrast, the GNU General Public 50License is intended to guarantee your freedom to share and change free 51software--to make sure the software is free for all its users. This 52General Public License applies to most of the Free Software 53Foundation's software and to any other program whose authors commit to 54using it. (Some other Free Software Foundation software is covered by 55the GNU Library General Public License instead.) You can apply it to 56your programs, too. 57 58 When we speak of free software, we are referring to freedom, not 59price. Our General Public Licenses are designed to make sure that you 60have the freedom to distribute copies of free software (and charge for 61this service if you wish), that you receive source code or can get it 62if you want it, that you can change the software or use pieces of it 63in new free programs; and that you know you can do these things. 64 65 To protect your rights, we need to make restrictions that forbid 66anyone to deny you these rights or to ask you to surrender the rights. 67These restrictions translate to certain responsibilities for you if you 68distribute copies of the software, or if you modify it. 69 70 For example, if you distribute copies of such a program, whether 71gratis or for a fee, you must give the recipients all the rights that 72you have. You must make sure that they, too, receive or can get the 73source code. And you must show them these terms so they know their 74rights. 75 76 We protect your rights with two steps: (1) copyright the software, and 77(2) offer you this license which gives you legal permission to copy, 78distribute and/or modify the software. 79 80 Also, for each author's protection and ours, we want to make certain 81that everyone understands that there is no warranty for this free 82software. If the software is modified by someone else and passed on, we 83want its recipients to know that what they have is not the original, so 84that any problems introduced by others will not reflect on the original 85authors' reputations. 86 87 Finally, any free program is threatened constantly by software 88patents. We wish to avoid the danger that redistributors of a free 89program will individually obtain patent licenses, in effect making the 90program proprietary. To prevent this, we have made it clear that any 91patent must be licensed for everyone's free use or not licensed at all. 92 93 The precise terms and conditions for copying, distribution and 94modification follow. 95 96 GNU GENERAL PUBLIC LICENSE 97 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 98 99 0. This License applies to any program or other work which contains 100a notice placed by the copyright holder saying it may be distributed 101under the terms of this General Public License. The "Program", below, 102refers to any such program or work, and a "work based on the Program" 103means either the Program or any derivative work under copyright law: 104that is to say, a work containing the Program or a portion of it, 105either verbatim or with modifications and/or translated into another 106language. (Hereinafter, translation is included without limitation in 107the term "modification".) Each licensee is addressed as "you". 108 109Activities other than copying, distribution and modification are not 110covered by this License; they are outside its scope. The act of 111running the Program is not restricted, and the output from the Program 112is covered only if its contents constitute a work based on the 113Program (independent of having been made by running the Program). 114Whether that is true depends on what the Program does. 115 116 1. You may copy and distribute verbatim copies of the Program's 117source code as you receive it, in any medium, provided that you 118conspicuously and appropriately publish on each copy an appropriate 119copyright notice and disclaimer of warranty; keep intact all the 120notices that refer to this License and to the absence of any warranty; 121and give any other recipients of the Program a copy of this License 122along with the Program. 123 124You may charge a fee for the physical act of transferring a copy, and 125you may at your option offer warranty protection in exchange for a fee. 126 127 2. You may modify your copy or copies of the Program or any portion 128of it, thus forming a work based on the Program, and copy and 129distribute such modifications or work under the terms of Section 1 130above, provided that you also meet all of these conditions: 131 132 a) You must cause the modified files to carry prominent notices 133 stating that you changed the files and the date of any change. 134 135 b) You must cause any work that you distribute or publish, that in 136 whole or in part contains or is derived from the Program or any 137 part thereof, to be licensed as a whole at no charge to all third 138 parties under the terms of this License. 139 140 c) If the modified program normally reads commands interactively 141 when run, you must cause it, when started running for such 142 interactive use in the most ordinary way, to print or display an 143 announcement including an appropriate copyright notice and a 144 notice that there is no warranty (or else, saying that you provide 145 a warranty) and that users may redistribute the program under 146 these conditions, and telling the user how to view a copy of this 147 License. (Exception: if the Program itself is interactive but 148 does not normally print such an announcement, your work based on 149 the Program is not required to print an announcement.) 150 151These requirements apply to the modified work as a whole. If 152identifiable sections of that work are not derived from the Program, 153and can be reasonably considered independent and separate works in 154themselves, then this License, and its terms, do not apply to those 155sections when you distribute them as separate works. But when you 156distribute the same sections as part of a whole which is a work based 157on the Program, the distribution of the whole must be on the terms of 158this License, whose permissions for other licensees extend to the 159entire whole, and thus to each and every part regardless of who wrote it. 160 161Thus, it is not the intent of this section to claim rights or contest 162your rights to work written entirely by you; rather, the intent is to 163exercise the right to control the distribution of derivative or 164collective works based on the Program. 165 166In addition, mere aggregation of another work not based on the Program 167with the Program (or with a work based on the Program) on a volume of 168a storage or distribution medium does not bring the other work under 169the scope of this License. 170 171 3. You may copy and distribute the Program (or a work based on it, 172under Section 2) in object code or executable form under the terms of 173Sections 1 and 2 above provided that you also do one of the following: 174 175 a) Accompany it with the complete corresponding machine-readable 176 source code, which must be distributed under the terms of Sections 177 1 and 2 above on a medium customarily used for software interchange; or, 178 179 b) Accompany it with a written offer, valid for at least three 180 years, to give any third party, for a charge no more than your 181 cost of physically performing source distribution, a complete 182 machine-readable copy of the corresponding source code, to be 183 distributed under the terms of Sections 1 and 2 above on a medium 184 customarily used for software interchange; or, 185 186 c) Accompany it with the information you received as to the offer 187 to distribute corresponding source code. (This alternative is 188 allowed only for noncommercial distribution and only if you 189 received the program in object code or executable form with such 190 an offer, in accord with Subsection b above.) 191 192The source code for a work means the preferred form of the work for 193making modifications to it. For an executable work, complete source 194code means all the source code for all modules it contains, plus any 195associated interface definition files, plus the scripts used to 196control compilation and installation of the executable. However, as a 197special exception, the source code distributed need not include 198anything that is normally distributed (in either source or binary 199form) with the major components (compiler, kernel, and so on) of the 200operating system on which the executable runs, unless that component 201itself accompanies the executable. 202 203If distribution of executable or object code is made by offering 204access to copy from a designated place, then offering equivalent 205access to copy the source code from the same place counts as 206distribution of the source code, even though third parties are not 207compelled to copy the source along with the object code. 208 209 4. You may not copy, modify, sublicense, or distribute the Program 210except as expressly provided under this License. Any attempt 211otherwise to copy, modify, sublicense or distribute the Program is 212void, and will automatically terminate your rights under this License. 213However, parties who have received copies, or rights, from you under 214this License will not have their licenses terminated so long as such 215parties remain in full compliance. 216 217 5. You are not required to accept this License, since you have not 218signed it. However, nothing else grants you permission to modify or 219distribute the Program or its derivative works. These actions are 220prohibited by law if you do not accept this License. Therefore, by 221modifying or distributing the Program (or any work based on the 222Program), you indicate your acceptance of this License to do so, and 223all its terms and conditions for copying, distributing or modifying 224the Program or works based on it. 225 226 6. Each time you redistribute the Program (or any work based on the 227Program), the recipient automatically receives a license from the 228original licensor to copy, distribute or modify the Program subject to 229these terms and conditions. You may not impose any further 230restrictions on the recipients' exercise of the rights granted herein. 231You are not responsible for enforcing compliance by third parties to 232this License. 233 234 7. If, as a consequence of a court judgment or allegation of patent 235infringement or for any other reason (not limited to patent issues), 236conditions are imposed on you (whether by court order, agreement or 237otherwise) that contradict the conditions of this License, they do not 238excuse you from the conditions of this License. If you cannot 239distribute so as to satisfy simultaneously your obligations under this 240License and any other pertinent obligations, then as a consequence you 241may not distribute the Program at all. For example, if a patent 242license would not permit royalty-free redistribution of the Program by 243all those who receive copies directly or indirectly through you, then 244the only way you could satisfy both it and this License would be to 245refrain entirely from distribution of the Program. 246 247If any portion of this section is held invalid or unenforceable under 248any particular circumstance, the balance of the section is intended to 249apply and the section as a whole is intended to apply in other 250circumstances. 251 252It is not the purpose of this section to induce you to infringe any 253patents or other property right claims or to contest validity of any 254such claims; this section has the sole purpose of protecting the 255integrity of the free software distribution system, which is 256implemented by public license practices. Many people have made 257generous contributions to the wide range of software distributed 258through that system in reliance on consistent application of that 259system; it is up to the author/donor to decide if he or she is willing 260to distribute software through any other system and a licensee cannot 261impose that choice. 262 263This section is intended to make thoroughly clear what is believed to 264be a consequence of the rest of this License. 265 266 8. If the distribution and/or use of the Program is restricted in 267certain countries either by patents or by copyrighted interfaces, the 268original copyright holder who places the Program under this License 269may add an explicit geographical distribution limitation excluding 270those countries, so that distribution is permitted only in or among 271countries not thus excluded. In such case, this License incorporates 272the limitation as if written in the body of this License. 273 274 9. The Free Software Foundation may publish revised and/or new versions 275of the General Public License from time to time. Such new versions will 276be similar in spirit to the present version, but may differ in detail to 277address new problems or concerns. 278 279Each version is given a distinguishing version number. If the Program 280specifies a version number of this License which applies to it and "any 281later version", you have the option of following the terms and conditions 282either of that version or of any later version published by the Free 283Software Foundation. If the Program does not specify a version number of 284this License, you may choose any version ever published by the Free Software 285Foundation. 286 287 10. If you wish to incorporate parts of the Program into other free 288programs whose distribution conditions are different, write to the author 289to ask for permission. For software which is copyrighted by the Free 290Software Foundation, write to the Free Software Foundation; we sometimes 291make exceptions for this. Our decision will be guided by the two goals 292of preserving the free status of all derivatives of our free software and 293of promoting the sharing and reuse of software generally. 294 295 NO WARRANTY 296 297 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 298FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 299OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 300PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 301OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 302MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 303TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 304PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 305REPAIR OR CORRECTION. 306 307 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 308WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 309REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 310INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 311OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 312TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 313YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 314PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 315POSSIBILITY OF SUCH DAMAGES. 316 317 END OF TERMS AND CONDITIONS 318 319 How to Apply These Terms to Your New Programs 320 321 If you develop a new program, and you want it to be of the greatest 322possible use to the public, the best way to achieve this is to make it 323free software which everyone can redistribute and change under these terms. 324 325 To do so, attach the following notices to the program. It is safest 326to attach them to the start of each source file to most effectively 327convey the exclusion of warranty; and each file should have at least 328the "copyright" line and a pointer to where the full notice is found. 329 330 <one line to give the program's name and a brief idea of what it does.> 331 Copyright (C) <year> <name of author> 332 333 This program is free software; you can redistribute it and/or modify 334 it under the terms of the GNU General Public License as published by 335 the Free Software Foundation; either version 2 of the License, or 336 (at your option) any later version. 337 338 This program is distributed in the hope that it will be useful, 339 but WITHOUT ANY WARRANTY; without even the implied warranty of 340 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 341 GNU General Public License for more details. 342 343 You should have received a copy of the GNU General Public License 344 along with this program; if not, write to the Free Software 345 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 346 347 348Also add information on how to contact you by electronic and paper mail. 349 350If the program is interactive, make it output a short notice like this 351when it starts in an interactive mode: 352 353 Gnomovision version 69, Copyright (C) year name of author 354 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 355 This is free software, and you are welcome to redistribute it 356 under certain conditions; type `show c' for details. 357 358The hypothetical commands `show w' and `show c' should show the appropriate 359parts of the General Public License. Of course, the commands you use may 360be called something other than `show w' and `show c'; they could even be 361mouse-clicks or menu items--whatever suits your program. 362 363You should also get your employer (if you work as a programmer) or your 364school, if any, to sign a "copyright disclaimer" for the program, if 365necessary. Here is a sample; alter the names: 366 367 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 368 `Gnomovision' (which makes passes at compilers) written by James Hacker. 369 370 <signature of Ty Coon>, 1 April 1989 371 Ty Coon, President of Vice 372 373This General Public License does not permit incorporating your program into 374proprietary programs. If your program is a subroutine library, you may 375consider it more useful to permit linking proprietary applications with the 376library. If this is what you want to do, use the GNU Library General 377Public License instead of this License. 378 379
