By contrast, the GNU General Public 37License is intended to guarantee your freedom to share and change free 38software--to make sure the software is free for all its users. This 39General Public License applies to most of the Free Software 40Foundation's software and to any other program whose authors commit to 41using it. (Some other Free Software Foundation software is covered by 42the GNU Library General Public License instead.) You can apply it to 43your programs, too. 44 45 When we speak of free software, we are referring to freedom, not 46price. Our General Public Licenses are designed to make sure that you 47have the freedom to distribute copies of free software (and charge for 48this service if you wish), that you receive source code or can get it 49if you want it, that you can change the software or use pieces of it 50in new free programs; and that you know you can do these things. 51 52 To protect your rights, we need to make restrictions that forbid 53anyone to deny you these rights or to ask you to surrender the rights. 54These restrictions translate to certain responsibilities for you if you 55distribute copies of the software, or if you modify it. 56 57 For example, if you distribute copies of such a program, whether 58gratis or for a fee, you must give the recipients all the rights that 59you have. You must make sure that they, too, receive or can get the 60source code. And you must show them these terms so they know their 61rights. 62 63 We protect your rights with two steps: (1) copyright the software, and 64(2) offer you this license which gives you legal permission to copy, 65distribute and/or modify the software. 66 67 Also, for each author's protection and ours, we want to make certain 68that everyone understands that there is no warranty for this free 69software. If the software is modified by someone else and passed on, we 70want its recipients to know that what they have is not the original, so 71that any problems introduced by others will not reflect on the original 72authors' reputations. 73 74 Finally, any free program is threatened constantly by software 75patents. We wish to avoid the danger that redistributors of a free 76program will individually obtain patent licenses, in effect making the 77program proprietary. To prevent this, we have made it clear that any 78patent must be licensed for everyone's free use or not licensed at all. 79 80 The precise terms and conditions for copying, distribution and 81modification follow. 82 83 GNU GENERAL PUBLIC LICENSE 84 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 85 86 0. This License applies to any program or other work which contains 87a notice placed by the copyright holder saying it may be distributed 88under the terms of this General Public License. The "Program", below, 89refers to any such program or work, and a "work based on the Program" 90means either the Program or any derivative work under copyright law: 91that is to say, a work containing the Program or a portion of it, 92either verbatim or with modifications and/or translated into another 93language. (Hereinafter, translation is included without limitation in 94the term "modification".) Each licensee is addressed as "you". 95 96Activities other than copying, distribution and modification are not 97covered by this License; they are outside its scope. The act of 98running the Program is not restricted, and the output from the Program 99is covered only if its contents constitute a work based on the 100Program (independent of having been made by running the Program). 101Whether that is true depends on what the Program does. 102 103 1. You may copy and distribute verbatim copies of the Program's 104source code as you receive it, in any medium, provided that you 105conspicuously and appropriately publish on each copy an appropriate 106copyright notice and disclaimer of warranty; keep intact all the 107notices that refer to this License and to the absence of any warranty; 108and give any other recipients of the Program a copy of this License 109along with the Program. 110 111You may charge a fee for the physical act of transferring a copy, and 112you may at your option offer warranty protection in exchange for a fee. 113 114 2. You may modify your copy or copies of the Program or any portion 115of it, thus forming a work based on the Program, and copy and 116distribute such modifications or work under the terms of Section 1 117above, provided that you also meet all of these conditions: 118 119 a) You must cause the modified files to carry prominent notices 120 stating that you changed the files and the date of any change. 121 122 b) You must cause any work that you distribute or publish, that in 123 whole or in part contains or is derived from the Program or any 124 part thereof, to be licensed as a whole at no charge to all third 125 parties under the terms of this License. 126 127 c) If the modified program normally reads commands interactively 128 when run, you must cause it, when started running for such 129 interactive use in the most ordinary way, to print or display an 130 announcement including an appropriate copyright notice and a 131 notice that there is no warranty (or else, saying that you provide 132 a warranty) and that users may redistribute the program under 133 these conditions, and telling the user how to view a copy of this 134 License. (Exception: if the Program itself is interactive but 135 does not normally print such an announcement, your work based on 136 the Program is not required to print an announcement.) 137 138These requirements apply to the modified work as a whole. If 139identifiable sections of that work are not derived from the Program, 140and can be reasonably considered independent and separate works in 141themselves, then this License, and its terms, do not apply to those 142sections when you distribute them as separate works. But when you 143distribute the same sections as part of a whole which is a work based 144on the Program, the distribution of the whole must be on the terms of 145this License, whose permissions for other licensees extend to the 146entire whole, and thus to each and every part regardless of who wrote it. 147 148Thus, it is not the intent of this section to claim rights or contest 149your rights to work written entirely by you; rather, the intent is to 150exercise the right to control the distribution of derivative or 151collective works based on the Program. 152 153In addition, mere aggregation of another work not based on the Program 154with the Program (or with a work based on the Program) on a volume of 155a storage or distribution medium does not bring the other work under 156the scope of this License. 157 158 3. You may copy and distribute the Program (or a work based on it, 159under Section 2) in object code or executable form under the terms of 160Sections 1 and 2 above provided that you also do one of the following: 161 162 a) Accompany it with the complete corresponding machine-readable 163 source code, which must be distributed under the terms of Sections 164 1 and 2 above on a medium customarily used for software interchange; or, 165 166 b) Accompany it with a written offer, valid for at least three 167 years, to give any third party, for a charge no more than your 168 cost of physically performing source distribution, a complete 169 machine-readable copy of the corresponding source code, to be 170 distributed under the terms of Sections 1 and 2 above on a medium 171 customarily used for software interchange; or, 172 173 c) Accompany it with the information you received as to the offer 174 to distribute corresponding source code. (This alternative is 175 allowed only for noncommercial distribution and only if you 176 received the program in object code or executable form with such 177 an offer, in accord with Subsection b above.) 178 179The source code for a work means the preferred form of the work for 180making modifications to it. For an executable work, complete source 181code means all the source code for all modules it contains, plus any 182associated interface definition files, plus the scripts used to 183control compilation and installation of the executable. However, as a 184special exception, the source code distributed need not include 185anything that is normally distributed (in either source or binary 186form) with the major components (compiler, kernel, and so on) of the 187operating system on which the executable runs, unless that component 188itself accompanies the executable. 189 190If distribution of executable or object code is made by offering 191access to copy from a designated place, then offering equivalent 192access to copy the source code from the same place counts as 193distribution of the source code, even though third parties are not 194compelled to copy the source along with the object code. 195 196 4. You may not copy, modify, sublicense, or distribute the Program 197except as expressly provided under this License. Any attempt 198otherwise to copy, modify, sublicense or distribute the Program is 199void, and will automatically terminate your rights under this License. 200However, parties who have received copies, or rights, from you under 201this License will not have their licenses terminated so long as such 202parties remain in full compliance. 203 204 5. You are not required to accept this License, since you have not 205signed it. However, nothing else grants you permission to modify or 206distribute the Program or its derivative works. These actions are 207prohibited by law if you do not accept this License. Therefore, by 208modifying or distributing the Program (or any work based on the 209Program), you indicate your acceptance of this License to do so, and 210all its terms and conditions for copying, distributing or modifying 211the Program or works based on it. 212 213 6. Each time you redistribute the Program (or any work based on the 214Program), the recipient automatically receives a license from the 215original licensor to copy, distribute or modify the Program subject to 216these terms and conditions. You may not impose any further 217restrictions on the recipients' exercise of the rights granted herein. 218You are not responsible for enforcing compliance by third parties to 219this License. 220 221 7. If, as a consequence of a court judgment or allegation of patent 222infringement or for any other reason (not limited to patent issues), 223conditions are imposed on you (whether by court order, agreement or 224otherwise) that contradict the conditions of this License, they do not 225excuse you from the conditions of this License. If you cannot 226distribute so as to satisfy simultaneously your obligations under this 227License and any other pertinent obligations, then as a consequence you 228may not distribute the Program at all. For example, if a patent 229license would not permit royalty-free redistribution of the Program by 230all those who receive copies directly or indirectly through you, then 231the only way you could satisfy both it and this License would be to 232refrain entirely from distribution of the Program. 233 234If any portion of this section is held invalid or unenforceable under 235any particular circumstance, the balance of the section is intended to 236apply and the section as a whole is intended to apply in other 237circumstances. 238 239It is not the purpose of this section to induce you to infringe any 240patents or other property right claims or to contest validity of any 241such claims; this section has the sole purpose of protecting the 242integrity of the free software distribution system, which is 243implemented by public license practices. Many people have made 244generous contributions to the wide range of software distributed 245through that system in reliance on consistent application of that 246system; it is up to the author/donor to decide if he or she is willing 247to distribute software through any other system and a licensee cannot 248impose that choice. 249 250This section is intended to make thoroughly clear what is believed to 251be a consequence of the rest of this License. 252 253 8. If the distribution and/or use of the Program is restricted in 254certain countries either by patents or by copyrighted interfaces, the 255original copyright holder who places the Program under this License 256may add an explicit geographical distribution limitation excluding 257those countries, so that distribution is permitted only in or among 258countries not thus excluded. In such case, this License incorporates 259the limitation as if written in the body of this License. 260 261 9. The Free Software Foundation may publish revised and/or new versions 262of the General Public License from time to time. Such new versions will 263be similar in spirit to the present version, but may differ in detail to 264address new problems or concerns. 265 266Each version is given a distinguishing version number. If the Program 267specifies a version number of this License which applies to it and "any 268later version", you have the option of following the terms and conditions 269either of that version or of any later version published by the Free 270Software Foundation. If the Program does not specify a version number of 271this License, you may choose any version ever published by the Free Software 272Foundation. 273 274 10. If you wish to incorporate parts of the Program into other free 275programs whose distribution conditions are different, write to the author 276to ask for permission. For software which is copyrighted by the Free 277Software Foundation, write to the Free Software Foundation; we sometimes 278make exceptions for this. Our decision will be guided by the two goals 279of preserving the free status of all derivatives of our free software and 280of promoting the sharing and reuse of software generally. 281 282 NO WARRANTY 283 284 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 285FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 286OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 287PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 288OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 289MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 290TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 291PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 292REPAIR OR CORRECTION. 293 294 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 295WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 296REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 297INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 298OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 299TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 300YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 301PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 302POSSIBILITY OF SUCH DAMAGES. 303 304 END OF TERMS AND CONDITIONS 305 306 How to Apply These Terms to Your New Programs 307 308 If you develop a new program, and you want it to be of the greatest 309possible use to the public, the best way to achieve this is to make it 310free software which everyone can redistribute and change under these terms. 311 312 To do so, attach the following notices to the program. It is safest 313to attach them to the start of each source file to most effectively 314convey the exclusion of warranty; and each file should have at least 315the "copyright" line and a pointer to where the full notice is found. 316 317 <one line to give the program's name and a brief idea of what it does.> 318 Copyright (C) <year> <name of author> 319 320 This program is free software; you can redistribute it and/or modify 321 it under the terms of the GNU General Public License as published by 322 the Free Software Foundation; either version 2 of the License, or 323 (at your option) any later version. 324 325 This program is distributed in the hope that it will be useful, 326 but WITHOUT ANY WARRANTY; without even the implied warranty of 327 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 328 GNU General Public License for more details. 329 330 You should have received a copy of the GNU General Public License 331 along with this program; if not, write to the Free Software 332 Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA 333 334 335Also add information on how to contact you by electronic and paper mail. 336 337If the program is interactive, make it output a short notice like this 338when it starts in an interactive mode: 339 340 Gnomovision version 69, Copyright (C) year name of author 341 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 342 This is free software, and you are welcome to redistribute it 343 under certain conditions; type `show c' for details. 344 345The hypothetical commands `show w' and `show c' should show the appropriate 346parts of the General Public License. Of course, the commands you use may 347be called something other than `show w' and `show c'; they could even be 348mouse-clicks or menu items--whatever suits your program. 349 350You should also get your employer (if you work as a programmer) or your 351school, if any, to sign a "copyright disclaimer" for the program, if 352necessary. Here is a sample; alter the names: 353 354 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 355 `Gnomovision' (which makes passes at compilers) written by James Hacker. 356 357 <signature of Ty Coon>, 1 April 1989 358 Ty Coon, President of Vice 359 360This General Public License does not permit incorporating your program into 361proprietary programs. If your program is a subroutine library, you may 362consider it more useful to permit linking proprietary applications with the 363library. If this is what you want to do, use the GNU Library General 364Public License instead of this License. 365
