By contrast, the GNU General Public 42License is intended to guarantee your freedom to share and change free 43software--to make sure the software is free for all its users. This 44General Public License applies to most of the Free Software 45Foundation's software and to any other program whose authors commit to 46using it. (Some other Free Software Foundation software is covered by 47the GNU Library General Public License instead.) You can apply it to 48your programs, too. 49 50 When we speak of free software, we are referring to freedom, not 51price. Our General Public Licenses are designed to make sure that you 52have the freedom to distribute copies of free software (and charge for 53this service if you wish), that you receive source code or can get it 54if you want it, that you can change the software or use pieces of it 55in new free programs; and that you know you can do these things. 56 57 To protect your rights, we need to make restrictions that forbid 58anyone to deny you these rights or to ask you to surrender the rights. 59These restrictions translate to certain responsibilities for you if you 60distribute copies of the software, or if you modify it. 61 62 For example, if you distribute copies of such a program, whether 63gratis or for a fee, you must give the recipients all the rights that 64you have. You must make sure that they, too, receive or can get the 65source code. And you must show them these terms so they know their 66rights. 67 68 We protect your rights with two steps: (1) copyright the software, and 69(2) offer you this license which gives you legal permission to copy, 70distribute and/or modify the software. 71 72 Also, for each author's protection and ours, we want to make certain 73that everyone understands that there is no warranty for this free 74software. If the software is modified by someone else and passed on, we 75want its recipients to know that what they have is not the original, so 76that any problems introduced by others will not reflect on the original 77authors' reputations. 78 79 Finally, any free program is threatened constantly by software 80patents. We wish to avoid the danger that redistributors of a free 81program will individually obtain patent licenses, in effect making the 82program proprietary. To prevent this, we have made it clear that any 83patent must be licensed for everyone's free use or not licensed at all. 84 85 The precise terms and conditions for copying, distribution and 86modification follow. 87 88 GNU GENERAL PUBLIC LICENSE 89 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 90 91 0. This License applies to any program or other work which contains 92a notice placed by the copyright holder saying it may be distributed 93under the terms of this General Public License. The "Program", below, 94refers to any such program or work, and a "work based on the Program" 95means either the Program or any derivative work under copyright law: 96that is to say, a work containing the Program or a portion of it, 97either verbatim or with modifications and/or translated into another 98language. (Hereinafter, translation is included without limitation in 99the term "modification".) Each licensee is addressed as "you". 100 101Activities other than copying, distribution and modification are not 102covered by this License; they are outside its scope. The act of 103running the Program is not restricted, and the output from the Program 104is covered only if its contents constitute a work based on the 105Program (independent of having been made by running the Program). 106Whether that is true depends on what the Program does. 107 108 1. You may copy and distribute verbatim copies of the Program's 109source code as you receive it, in any medium, provided that you 110conspicuously and appropriately publish on each copy an appropriate 111copyright notice and disclaimer of warranty; keep intact all the 112notices that refer to this License and to the absence of any warranty; 113and give any other recipients of the Program a copy of this License 114along with the Program. 115 116You may charge a fee for the physical act of transferring a copy, and 117you may at your option offer warranty protection in exchange for a fee. 118 119 2. You may modify your copy or copies of the Program or any portion 120of it, thus forming a work based on the Program, and copy and 121distribute such modifications or work under the terms of Section 1 122above, provided that you also meet all of these conditions: 123 124 a) You must cause the modified files to carry prominent notices 125 stating that you changed the files and the date of any change. 126 127 b) You must cause any work that you distribute or publish, that in 128 whole or in part contains or is derived from the Program or any 129 part thereof, to be licensed as a whole at no charge to all third 130 parties under the terms of this License. 131 132 c) If the modified program normally reads commands interactively 133 when run, you must cause it, when started running for such 134 interactive use in the most ordinary way, to print or display an 135 announcement including an appropriate copyright notice and a 136 notice that there is no warranty (or else, saying that you provide 137 a warranty) and that users may redistribute the program under 138 these conditions, and telling the user how to view a copy of this 139 License. (Exception: if the Program itself is interactive but 140 does not normally print such an announcement, your work based on 141 the Program is not required to print an announcement.) 142 143These requirements apply to the modified work as a whole. If 144identifiable sections of that work are not derived from the Program, 145and can be reasonably considered independent and separate works in 146themselves, then this License, and its terms, do not apply to those 147sections when you distribute them as separate works. But when you 148distribute the same sections as part of a whole which is a work based 149on the Program, the distribution of the whole must be on the terms of 150this License, whose permissions for other licensees extend to the 151entire whole, and thus to each and every part regardless of who wrote it. 152 153Thus, it is not the intent of this section to claim rights or contest 154your rights to work written entirely by you; rather, the intent is to 155exercise the right to control the distribution of derivative or 156collective works based on the Program. 157 158In addition, mere aggregation of another work not based on the Program 159with the Program (or with a work based on the Program) on a volume of 160a storage or distribution medium does not bring the other work under 161the scope of this License. 162 163 3. You may copy and distribute the Program (or a work based on it, 164under Section 2) in object code or executable form under the terms of 165Sections 1 and 2 above provided that you also do one of the following: 166 167 a) Accompany it with the complete corresponding machine-readable 168 source code, which must be distributed under the terms of Sections 169 1 and 2 above on a medium customarily used for software interchange; or, 170 171 b) Accompany it with a written offer, valid for at least three 172 years, to give any third party, for a charge no more than your 173 cost of physically performing source distribution, a complete 174 machine-readable copy of the corresponding source code, to be 175 distributed under the terms of Sections 1 and 2 above on a medium 176 customarily used for software interchange; or, 177 178 c) Accompany it with the information you received as to the offer 179 to distribute corresponding source code. (This alternative is 180 allowed only for noncommercial distribution and only if you 181 received the program in object code or executable form with such 182 an offer, in accord with Subsection b above.) 183 184The source code for a work means the preferred form of the work for 185making modifications to it. For an executable work, complete source 186code means all the source code for all modules it contains, plus any 187associated interface definition files, plus the scripts used to 188control compilation and installation of the executable. However, as a 189special exception, the source code distributed need not include 190anything that is normally distributed (in either source or binary 191form) with the major components (compiler, kernel, and so on) of the 192operating system on which the executable runs, unless that component 193itself accompanies the executable. 194 195If distribution of executable or object code is made by offering 196access to copy from a designated place, then offering equivalent 197access to copy the source code from the same place counts as 198distribution of the source code, even though third parties are not 199compelled to copy the source along with the object code. 200 201 4. You may not copy, modify, sublicense, or distribute the Program 202except as expressly provided under this License. Any attempt 203otherwise to copy, modify, sublicense or distribute the Program is 204void, and will automatically terminate your rights under this License. 205However, parties who have received copies, or rights, from you under 206this License will not have their licenses terminated so long as such 207parties remain in full compliance. 208 209 5. You are not required to accept this License, since you have not 210signed it. However, nothing else grants you permission to modify or 211distribute the Program or its derivative works. These actions are 212prohibited by law if you do not accept this License. Therefore, by 213modifying or distributing the Program (or any work based on the 214Program), you indicate your acceptance of this License to do so, and 215all its terms and conditions for copying, distributing or modifying 216the Program or works based on it. 217 218 6. Each time you redistribute the Program (or any work based on the 219Program), the recipient automatically receives a license from the 220original licensor to copy, distribute or modify the Program subject to 221these terms and conditions. You may not impose any further 222restrictions on the recipients' exercise of the rights granted herein. 223You are not responsible for enforcing compliance by third parties to 224this License. 225 226 7. If, as a consequence of a court judgment or allegation of patent 227infringement or for any other reason (not limited to patent issues), 228conditions are imposed on you (whether by court order, agreement or 229otherwise) that contradict the conditions of this License, they do not 230excuse you from the conditions of this License. If you cannot 231distribute so as to satisfy simultaneously your obligations under this 232License and any other pertinent obligations, then as a consequence you 233may not distribute the Program at all. For example, if a patent 234license would not permit royalty-free redistribution of the Program by 235all those who receive copies directly or indirectly through you, then 236the only way you could satisfy both it and this License would be to 237refrain entirely from distribution of the Program. 238 239If any portion of this section is held invalid or unenforceable under 240any particular circumstance, the balance of the section is intended to 241apply and the section as a whole is intended to apply in other 242circumstances. 243 244It is not the purpose of this section to induce you to infringe any 245patents or other property right claims or to contest validity of any 246such claims; this section has the sole purpose of protecting the 247integrity of the free software distribution system, which is 248implemented by public license practices. Many people have made 249generous contributions to the wide range of software distributed 250through that system in reliance on consistent application of that 251system; it is up to the author/donor to decide if he or she is willing 252to distribute software through any other system and a licensee cannot 253impose that choice. 254 255This section is intended to make thoroughly clear what is believed to 256be a consequence of the rest of this License. 257 258 8. If the distribution and/or use of the Program is restricted in 259certain countries either by patents or by copyrighted interfaces, the 260original copyright holder who places the Program under this License 261may add an explicit geographical distribution limitation excluding 262those countries, so that distribution is permitted only in or among 263countries not thus excluded. In such case, this License incorporates 264the limitation as if written in the body of this License. 265 266 9. The Free Software Foundation may publish revised and/or new versions 267of the General Public License from time to time. Such new versions will 268be similar in spirit to the present version, but may differ in detail to 269address new problems or concerns. 270 271Each version is given a distinguishing version number. If the Program 272specifies a version number of this License which applies to it and "any 273later version", you have the option of following the terms and conditions 274either of that version or of any later version published by the Free 275Software Foundation. If the Program does not specify a version number of 276this License, you may choose any version ever published by the Free Software 277Foundation. 278 279 10. If you wish to incorporate parts of the Program into other free 280programs whose distribution conditions are different, write to the author 281to ask for permission. For software which is copyrighted by the Free 282Software Foundation, write to the Free Software Foundation; we sometimes 283make exceptions for this. Our decision will be guided by the two goals 284of preserving the free status of all derivatives of our free software and 285of promoting the sharing and reuse of software generally. 286 287 NO WARRANTY 288 289 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 290FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 291OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 292PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 293OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 294MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 295TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 296PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 297REPAIR OR CORRECTION. 298 299 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 300WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 301REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 302INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 303OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 304TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 305YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 306PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 307POSSIBILITY OF SUCH DAMAGES. 308 309 END OF TERMS AND CONDITIONS 310 311 How to Apply These Terms to Your New Programs 312 313 If you develop a new program, and you want it to be of the greatest 314possible use to the public, the best way to achieve this is to make it 315free software which everyone can redistribute and change under these terms. 316 317 To do so, attach the following notices to the program. It is safest 318to attach them to the start of each source file to most effectively 319convey the exclusion of warranty; and each file should have at least 320the "copyright" line and a pointer to where the full notice is found. 321 322 <one line to give the program's name and a brief idea of what it does.> 323 Copyright (C) <year> <name of author> 324 325 This program is free software; you can redistribute it and/or modify 326 it under the terms of the GNU General Public License as published by 327 the Free Software Foundation; either version 2 of the License, or 328 (at your option) any later version. 329 330 This program is distributed in the hope that it will be useful, 331 but WITHOUT ANY WARRANTY; without even the implied warranty of 332 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 333 GNU General Public License for more details. 334 335 You should have received a copy of the GNU General Public License 336 along with this program; if not, write to the Free Software 337 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 338 339 340Also add information on how to contact you by electronic and paper mail. 341 342If the program is interactive, make it output a short notice like this 343when it starts in an interactive mode: 344 345 Gnomovision version 69, Copyright (C) year name of author 346 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 347 This is free software, and you are welcome to redistribute it 348 under certain conditions; type `show c' for details. 349 350The hypothetical commands `show w' and `show c' should show the appropriate 351parts of the General Public License. Of course, the commands you use may 352be called something other than `show w' and `show c'; they could even be 353mouse-clicks or menu items--whatever suits your program. 354 355You should also get your employer (if you work as a programmer) or your 356school, if any, to sign a "copyright disclaimer" for the program, if 357necessary. Here is a sample; alter the names: 358 359 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 360 `Gnomovision' (which makes passes at compilers) written by James Hacker. 361 362 <signature of Ty Coon>, 1 April 1989 363 Ty Coon, President of Vice 364 365This General Public License does not permit incorporating your program into 366proprietary programs. If your program is a subroutine library, you may 367consider it more useful to permit linking proprietary applications with the 368library. If this is what you want to do, use the GNU Library General 369Public License instead of this License. 370
