By contrast, the GNU General Public 35License is intended to guarantee your freedom to share and change free 36software--to make sure the software is free for all its users. This 37General Public License applies to most of the Free Software 38Foundation's software and to any other program whose authors commit to 39using it. (Some other Free Software Foundation software is covered by 40the GNU Library General Public License instead.) You can apply it to 41your programs, too. 42 43 When we speak of free software, we are referring to freedom, not 44price. Our General Public Licenses are designed to make sure that you 45have the freedom to distribute copies of free software (and charge for 46this service if you wish), that you receive source code or can get it 47if you want it, that you can change the software or use pieces of it 48in new free programs; and that you know you can do these things. 49 50 To protect your rights, we need to make restrictions that forbid 51anyone to deny you these rights or to ask you to surrender the rights. 52These restrictions translate to certain responsibilities for you if you 53distribute copies of the software, or if you modify it. 54 55 For example, if you distribute copies of such a program, whether 56gratis or for a fee, you must give the recipients all the rights that 57you have. You must make sure that they, too, receive or can get the 58source code. And you must show them these terms so they know their 59rights. 60 61 We protect your rights with two steps: (1) copyright the software, and 62(2) offer you this license which gives you legal permission to copy, 63distribute and/or modify the software. 64 65 Also, for each author's protection and ours, we want to make certain 66that everyone understands that there is no warranty for this free 67software. If the software is modified by someone else and passed on, we 68want its recipients to know that what they have is not the original, so 69that any problems introduced by others will not reflect on the original 70authors' reputations. 71 72 Finally, any free program is threatened constantly by software 73patents. We wish to avoid the danger that redistributors of a free 74program will individually obtain patent licenses, in effect making the 75program proprietary. To prevent this, we have made it clear that any 76patent must be licensed for everyone's free use or not licensed at all. 77 78 The precise terms and conditions for copying, distribution and 79modification follow. 80 81 GNU GENERAL PUBLIC LICENSE 82 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 83 84 0. This License applies to any program or other work which contains 85a notice placed by the copyright holder saying it may be distributed 86under the terms of this General Public License. The "Program", below, 87refers to any such program or work, and a "work based on the Program" 88means either the Program or any derivative work under copyright law: 89that is to say, a work containing the Program or a portion of it, 90either verbatim or with modifications and/or translated into another 91language. (Hereinafter, translation is included without limitation in 92the term "modification".) Each licensee is addressed as "you". 93 94Activities other than copying, distribution and modification are not 95covered by this License; they are outside its scope. The act of 96running the Program is not restricted, and the output from the Program 97is covered only if its contents constitute a work based on the 98Program (independent of having been made by running the Program). 99Whether that is true depends on what the Program does. 100 101 1. You may copy and distribute verbatim copies of the Program's 102source code as you receive it, in any medium, provided that you 103conspicuously and appropriately publish on each copy an appropriate 104copyright notice and disclaimer of warranty; keep intact all the 105notices that refer to this License and to the absence of any warranty; 106and give any other recipients of the Program a copy of this License 107along with the Program. 108 109You may charge a fee for the physical act of transferring a copy, and 110you may at your option offer warranty protection in exchange for a fee. 111 112 2. You may modify your copy or copies of the Program or any portion 113of it, thus forming a work based on the Program, and copy and 114distribute such modifications or work under the terms of Section 1 115above, provided that you also meet all of these conditions: 116 117 a) You must cause the modified files to carry prominent notices 118 stating that you changed the files and the date of any change. 119 120 b) You must cause any work that you distribute or publish, that in 121 whole or in part contains or is derived from the Program or any 122 part thereof, to be licensed as a whole at no charge to all third 123 parties under the terms of this License. 124 125 c) If the modified program normally reads commands interactively 126 when run, you must cause it, when started running for such 127 interactive use in the most ordinary way, to print or display an 128 announcement including an appropriate copyright notice and a 129 notice that there is no warranty (or else, saying that you provide 130 a warranty) and that users may redistribute the program under 131 these conditions, and telling the user how to view a copy of this 132 License. (Exception: if the Program itself is interactive but 133 does not normally print such an announcement, your work based on 134 the Program is not required to print an announcement.) 135 136These requirements apply to the modified work as a whole. If 137identifiable sections of that work are not derived from the Program, 138and can be reasonably considered independent and separate works in 139themselves, then this License, and its terms, do not apply to those 140sections when you distribute them as separate works. But when you 141distribute the same sections as part of a whole which is a work based 142on the Program, the distribution of the whole must be on the terms of 143this License, whose permissions for other licensees extend to the 144entire whole, and thus to each and every part regardless of who wrote it. 145 146Thus, it is not the intent of this section to claim rights or contest 147your rights to work written entirely by you; rather, the intent is to 148exercise the right to control the distribution of derivative or 149collective works based on the Program. 150 151In addition, mere aggregation of another work not based on the Program 152with the Program (or with a work based on the Program) on a volume of 153a storage or distribution medium does not bring the other work under 154the scope of this License. 155 156 3. You may copy and distribute the Program (or a work based on it, 157under Section 2) in object code or executable form under the terms of 158Sections 1 and 2 above provided that you also do one of the following: 159 160 a) Accompany it with the complete corresponding machine-readable 161 source code, which must be distributed under the terms of Sections 162 1 and 2 above on a medium customarily used for software interchange; or, 163 164 b) Accompany it with a written offer, valid for at least three 165 years, to give any third party, for a charge no more than your 166 cost of physically performing source distribution, a complete 167 machine-readable copy of the corresponding source code, to be 168 distributed under the terms of Sections 1 and 2 above on a medium 169 customarily used for software interchange; or, 170 171 c) Accompany it with the information you received as to the offer 172 to distribute corresponding source code. (This alternative is 173 allowed only for noncommercial distribution and only if you 174 received the program in object code or executable form with such 175 an offer, in accord with Subsection b above.) 176 177The source code for a work means the preferred form of the work for 178making modifications to it. For an executable work, complete source 179code means all the source code for all modules it contains, plus any 180associated interface definition files, plus the scripts used to 181control compilation and installation of the executable. However, as a 182special exception, the source code distributed need not include 183anything that is normally distributed (in either source or binary 184form) with the major components (compiler, kernel, and so on) of the 185operating system on which the executable runs, unless that component 186itself accompanies the executable. 187 188If distribution of executable or object code is made by offering 189access to copy from a designated place, then offering equivalent 190access to copy the source code from the same place counts as 191distribution of the source code, even though third parties are not 192compelled to copy the source along with the object code. 193 194 4. You may not copy, modify, sublicense, or distribute the Program 195except as expressly provided under this License. Any attempt 196otherwise to copy, modify, sublicense or distribute the Program is 197void, and will automatically terminate your rights under this License. 198However, parties who have received copies, or rights, from you under 199this License will not have their licenses terminated so long as such 200parties remain in full compliance. 201 202 5. You are not required to accept this License, since you have not 203signed it. However, nothing else grants you permission to modify or 204distribute the Program or its derivative works. These actions are 205prohibited by law if you do not accept this License. Therefore, by 206modifying or distributing the Program (or any work based on the 207Program), you indicate your acceptance of this License to do so, and 208all its terms and conditions for copying, distributing or modifying 209the Program or works based on it. 210 211 6. Each time you redistribute the Program (or any work based on the 212Program), the recipient automatically receives a license from the 213original licensor to copy, distribute or modify the Program subject to 214these terms and conditions. You may not impose any further 215restrictions on the recipients' exercise of the rights granted herein. 216You are not responsible for enforcing compliance by third parties to 217this License. 218 219 7. If, as a consequence of a court judgment or allegation of patent 220infringement or for any other reason (not limited to patent issues), 221conditions are imposed on you (whether by court order, agreement or 222otherwise) that contradict the conditions of this License, they do not 223excuse you from the conditions of this License. If you cannot 224distribute so as to satisfy simultaneously your obligations under this 225License and any other pertinent obligations, then as a consequence you 226may not distribute the Program at all. For example, if a patent 227license would not permit royalty-free redistribution of the Program by 228all those who receive copies directly or indirectly through you, then 229the only way you could satisfy both it and this License would be to 230refrain entirely from distribution of the Program. 231 232If any portion of this section is held invalid or unenforceable under 233any particular circumstance, the balance of the section is intended to 234apply and the section as a whole is intended to apply in other 235circumstances. 236 237It is not the purpose of this section to induce you to infringe any 238patents or other property right claims or to contest validity of any 239such claims; this section has the sole purpose of protecting the 240integrity of the free software distribution system, which is 241implemented by public license practices. Many people have made 242generous contributions to the wide range of software distributed 243through that system in reliance on consistent application of that 244system; it is up to the author/donor to decide if he or she is willing 245to distribute software through any other system and a licensee cannot 246impose that choice. 247 248This section is intended to make thoroughly clear what is believed to 249be a consequence of the rest of this License. 250 251 8. If the distribution and/or use of the Program is restricted in 252certain countries either by patents or by copyrighted interfaces, the 253original copyright holder who places the Program under this License 254may add an explicit geographical distribution limitation excluding 255those countries, so that distribution is permitted only in or among 256countries not thus excluded. In such case, this License incorporates 257the limitation as if written in the body of this License. 258 259 9. The Free Software Foundation may publish revised and/or new versions 260of the General Public License from time to time. Such new versions will 261be similar in spirit to the present version, but may differ in detail to 262address new problems or concerns. 263 264Each version is given a distinguishing version number. If the Program 265specifies a version number of this License which applies to it and "any 266later version", you have the option of following the terms and conditions 267either of that version or of any later version published by the Free 268Software Foundation. If the Program does not specify a version number of 269this License, you may choose any version ever published by the Free Software 270Foundation. 271 272 10. If you wish to incorporate parts of the Program into other free 273programs whose distribution conditions are different, write to the author 274to ask for permission. For software which is copyrighted by the Free 275Software Foundation, write to the Free Software Foundation; we sometimes 276make exceptions for this. Our decision will be guided by the two goals 277of preserving the free status of all derivatives of our free software and 278of promoting the sharing and reuse of software generally. 279 280 NO WARRANTY 281 282 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 283FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 284OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 285PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 286OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 287MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 288TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 289PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 290REPAIR OR CORRECTION. 291 292 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 293WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 294REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 295INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 296OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 297TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 298YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 299PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 300POSSIBILITY OF SUCH DAMAGES. 301 302 END OF TERMS AND CONDITIONS 303 304 How to Apply These Terms to Your New Programs 305 306 If you develop a new program, and you want it to be of the greatest 307possible use to the public, the best way to achieve this is to make it 308free software which everyone can redistribute and change under these terms. 309 310 To do so, attach the following notices to the program. It is safest 311to attach them to the start of each source file to most effectively 312convey the exclusion of warranty; and each file should have at least 313the "copyright" line and a pointer to where the full notice is found. 314 315 <one line to give the program's name and a brief idea of what it does.> 316 Copyright (C) <year> <name of author> 317 318 This program is free software; you can redistribute it and/or modify 319 it under the terms of the GNU General Public License as published by 320 the Free Software Foundation; either version 2 of the License, or 321 (at your option) any later version. 322 323 This program is distributed in the hope that it will be useful, 324 but WITHOUT ANY WARRANTY; without even the implied warranty of 325 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 326 GNU General Public License for more details. 327 328 You should have received a copy of the GNU General Public License 329 along with this program; if not, write to the Free Software 330 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA 331 332 333Also add information on how to contact you by electronic and paper mail. 334 335If the program is interactive, make it output a short notice like this 336when it starts in an interactive mode: 337 338 Gnomovision version 69, Copyright (C) year name of author 339 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 340 This is free software, and you are welcome to redistribute it 341 under certain conditions; type `show c' for details. 342 343The hypothetical commands `show w' and `show c' should show the appropriate 344parts of the General Public License. Of course, the commands you use may 345be called something other than `show w' and `show c'; they could even be 346mouse-clicks or menu items--whatever suits your program. 347 348You should also get your employer (if you work as a programmer) or your 349school, if any, to sign a "copyright disclaimer" for the program, if 350necessary. Here is a sample; alter the names: 351 352 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 353 `Gnomovision' (which makes passes at compilers) written by James Hacker. 354 355 <signature of Ty Coon>, 1 April 1989 356 Ty Coon, President of Vice 357 358This General Public License does not permit incorporating your program into 359proprietary programs. If your program is a subroutine library, you may 360consider it more useful to permit linking proprietary applications with the 361library. If this is what you want to do, use the GNU Library General 362Public License instead of this License. 363
