By contrast, the GNU General Public 67: License is intended to guarantee your freedom to share and change free 68: software--to make sure the software is free for all its users. This 69: General Public License applies to most of the Free Software 70: Foundation's software and to any other program whose authors commit to 71: using it. (Some other Free Software Foundation software is covered by 72: the GNU Library General Public License instead.) You can apply it to 73: your programs, too. 74: 75: When we speak of free software, we are referring to freedom, not 76: price. Our General Public Licenses are designed to make sure that you 77: have the freedom to distribute copies of free software (and charge for 78: this service if you wish), that you receive source code or can get it 79: if you want it, that you can change the software or use pieces of it 80: in new free programs; and that you know you can do these things. 81: 82: To protect your rights, we need to make restrictions that forbid 83: anyone to deny you these rights or to ask you to surrender the rights. 84: These restrictions translate to certain responsibilities for you if you 85: distribute copies of the software, or if you modify it. 86: 87: For example, if you distribute copies of such a program, whether 88: gratis or for a fee, you must give the recipients all the rights that 89: you have. You must make sure that they, too, receive or can get the 90: source code. And you must show them these terms so they know their 91: rights. 92: 93: We protect your rights with two steps: (1) copyright the software, and 94: (2) offer you this license which gives you legal permission to copy, 95: distribute and/or modify the software. 96: 97: Also, for each author's protection and ours, we want to make certain 98: that everyone understands that there is no warranty for this free 99: software. If the software is modified by someone else and passed on, we 100: want its recipients to know that what they have is not the original, so 101: that any problems introduced by others will not reflect on the original 102: authors' reputations. 103: 104: Finally, any free program is threatened constantly by software 105: patents. We wish to avoid the danger that redistributors of a free 106: program will individually obtain patent licenses, in effect making the 107: program proprietary. To prevent this, we have made it clear that any 108: patent must be licensed for everyone's free use or not licensed at all. 109: 110: The precise terms and conditions for copying, distribution and 111: modification follow. 112: 113: GNU GENERAL PUBLIC LICENSE 114: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 115: 116: 0. This License applies to any program or other work which contains 117: a notice placed by the copyright holder saying it may be distributed 118: under the terms of this General Public License. The "Program", below, 119: refers to any such program or work, and a "work based on the Program" 120: means either the Program or any derivative work under copyright law: 121: that is to say, a work containing the Program or a portion of it, 122: either verbatim or with modifications and/or translated into another 123: language. (Hereinafter, translation is included without limitation in 124: the term "modification".) Each licensee is addressed as "you". 125: 126: Activities other than copying, distribution and modification are not 127: covered by this License; they are outside its scope. The act of 128: running the Program is not restricted, and the output from the Program 129: is covered only if its contents constitute a work based on the 130: Program (independent of having been made by running the Program). 131: Whether that is true depends on what the Program does. 132: 133: 1. You may copy and distribute verbatim copies of the Program's 134: source code as you receive it, in any medium, provided that you 135: conspicuously and appropriately publish on each copy an appropriate 136: copyright notice and disclaimer of warranty; keep intact all the 137: notices that refer to this License and to the absence of any warranty; 138: and give any other recipients of the Program a copy of this License 139: along with the Program. 140: 141: You may charge a fee for the physical act of transferring a copy, and 142: you may at your option offer warranty protection in exchange for a fee. 143: 144: 2. You may modify your copy or copies of the Program or any portion 145: of it, thus forming a work based on the Program, and copy and 146: distribute such modifications or work under the terms of Section 1 147: above, provided that you also meet all of these conditions: 148: 149: a) You must cause the modified files to carry prominent notices 150: stating that you changed the files and the date of any change. 151: 152: b) You must cause any work that you distribute or publish, that in 153: whole or in part contains or is derived from the Program or any 154: part thereof, to be licensed as a whole at no charge to all third 155: parties under the terms of this License. 156: 157: c) If the modified program normally reads commands interactively 158: when run, you must cause it, when started running for such 159: interactive use in the most ordinary way, to print or display an 160: announcement including an appropriate copyright notice and a 161: notice that there is no warranty (or else, saying that you provide 162: a warranty) and that users may redistribute the program under 163: these conditions, and telling the user how to view a copy of this 164: License. (Exception: if the Program itself is interactive but 165: does not normally print such an announcement, your work based on 166: the Program is not required to print an announcement.) 167: 168: These requirements apply to the modified work as a whole. If 169: identifiable sections of that work are not derived from the Program, 170: and can be reasonably considered independent and separate works in 171: themselves, then this License, and its terms, do not apply to those 172: sections when you distribute them as separate works. But when you 173: distribute the same sections as part of a whole which is a work based 174: on the Program, the distribution of the whole must be on the terms of 175: this License, whose permissions for other licensees extend to the 176: entire whole, and thus to each and every part regardless of who wrote it. 177: 178: Thus, it is not the intent of this section to claim rights or contest 179: your rights to work written entirely by you; rather, the intent is to 180: exercise the right to control the distribution of derivative or 181: collective works based on the Program. 182: 183: In addition, mere aggregation of another work not based on the Program 184: with the Program (or with a work based on the Program) on a volume of 185: a storage or distribution medium does not bring the other work under 186: the scope of this License. 187: 188: 3. You may copy and distribute the Program (or a work based on it, 189: under Section 2) in object code or executable form under the terms of 190: Sections 1 and 2 above provided that you also do one of the following: 191: 192: a) Accompany it with the complete corresponding machine-readable 193: source code, which must be distributed under the terms of Sections 194: 1 and 2 above on a medium customarily used for software interchange; or, 195: 196: b) Accompany it with a written offer, valid for at least three 197: years, to give any third party, for a charge no more than your 198: cost of physically performing source distribution, a complete 199: machine-readable copy of the corresponding source code, to be 200: distributed under the terms of Sections 1 and 2 above on a medium 201: customarily used for software interchange; or, 202: 203: c) Accompany it with the information you received as to the offer 204: to distribute corresponding source code. (This alternative is 205: allowed only for noncommercial distribution and only if you 206: received the program in object code or executable form with such 207: an offer, in accord with Subsection b above.) 208: 209: The source code for a work means the preferred form of the work for 210: making modifications to it. For an executable work, complete source 211: code means all the source code for all modules it contains, plus any 212: associated interface definition files, plus the scripts used to 213: control compilation and installation of the executable. However, as a 214: special exception, the source code distributed need not include 215: anything that is normally distributed (in either source or binary 216: form) with the major components (compiler, kernel, and so on) of the 217: operating system on which the executable runs, unless that component 218: itself accompanies the executable. 219: 220: If distribution of executable or object code is made by offering 221: access to copy from a designated place, then offering equivalent 222: access to copy the source code from the same place counts as 223: distribution of the source code, even though third parties are not 224: compelled to copy the source along with the object code. 225: 226: 4. You may not copy, modify, sublicense, or distribute the Program 227: except as expressly provided under this License. Any attempt 228: otherwise to copy, modify, sublicense or distribute the Program is 229: void, and will automatically terminate your rights under this License. 230: However, parties who have received copies, or rights, from you under 231: this License will not have their licenses terminated so long as such 232: parties remain in full compliance. 233: 234: 5. You are not required to accept this License, since you have not 235: signed it. However, nothing else grants you permission to modify or 236: distribute the Program or its derivative works. These actions are 237: prohibited by law if you do not accept this License. Therefore, by 238: modifying or distributing the Program (or any work based on the 239: Program), you indicate your acceptance of this License to do so, and 240: all its terms and conditions for copying, distributing or modifying 241: the Program or works based on it. 242: 243: 6. Each time you redistribute the Program (or any work based on the 244: Program), the recipient automatically receives a license from the 245: original licensor to copy, distribute or modify the Program subject to 246: these terms and conditions. You may not impose any further 247: restrictions on the recipients' exercise of the rights granted herein. 248: You are not responsible for enforcing compliance by third parties to 249: this License. 250: 251: 7. If, as a consequence of a court judgment or allegation of patent 252: infringement or for any other reason (not limited to patent issues), 253: conditions are imposed on you (whether by court order, agreement or 254: otherwise) that contradict the conditions of this License, they do not 255: excuse you from the conditions of this License. If you cannot 256: distribute so as to satisfy simultaneously your obligations under this 257: License and any other pertinent obligations, then as a consequence you 258: may not distribute the Program at all. For example, if a patent 259: license would not permit royalty-free redistribution of the Program by 260: all those who receive copies directly or indirectly through you, then 261: the only way you could satisfy both it and this License would be to 262: refrain entirely from distribution of the Program. 263: 264: If any portion of this section is held invalid or unenforceable under 265: any particular circumstance, the balance of the section is intended to 266: apply and the section as a whole is intended to apply in other 267: circumstances. 268: 269: It is not the purpose of this section to induce you to infringe any 270: patents or other property right claims or to contest validity of any 271: such claims; this section has the sole purpose of protecting the 272: integrity of the free software distribution system, which is 273: implemented by public license practices. Many people have made 274: generous contributions to the wide range of software distributed 275: through that system in reliance on consistent application of that 276: system; it is up to the author/donor to decide if he or she is willing 277: to distribute software through any other system and a licensee cannot 278: impose that choice. 279: 280: This section is intended to make thoroughly clear what is believed to 281: be a consequence of the rest of this License. 282: 283: 8. If the distribution and/or use of the Program is restricted in 284: certain countries either by patents or by copyrighted interfaces, the 285: original copyright holder who places the Program under this License 286: may add an explicit geographical distribution limitation excluding 287: those countries, so that distribution is permitted only in or among 288: countries not thus excluded. In such case, this License incorporates 289: the limitation as if written in the body of this License. 290: 291: 9. The Free Software Foundation may publish revised and/or new versions 292: of the General Public License from time to time. Such new versions will 293: be similar in spirit to the present version, but may differ in detail to 294: address new problems or concerns. 295: 296: Each version is given a distinguishing version number. If the Program 297: specifies a version number of this License which applies to it and "any 298: later version", you have the option of following the terms and conditions 299: either of that version or of any later version published by the Free 300: Software Foundation. If the Program does not specify a version number of 301: this License, you may choose any version ever published by the Free Software 302: Foundation. 303: 304: 10. If you wish to incorporate parts of the Program into other free 305: programs whose distribution conditions are different, write to the author 306: to ask for permission. For software which is copyrighted by the Free 307: Software Foundation, write to the Free Software Foundation; we sometimes 308: make exceptions for this. Our decision will be guided by the two goals 309: of preserving the free status of all derivatives of our free software and 310: of promoting the sharing and reuse of software generally. 311: 312: NO WARRANTY 313: 314: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 315: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 316: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 317: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 318: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 319: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 320: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 321: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 322: REPAIR OR CORRECTION. 323: 324: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 325: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 326: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 327: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 328: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 329: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 330: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 331: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 332: POSSIBILITY OF SUCH DAMAGES. 333: 334: END OF TERMS AND CONDITIONS 335: 336: How to Apply These Terms to Your New Programs 337: 338: If you develop a new program, and you want it to be of the greatest 339: possible use to the public, the best way to achieve this is to make it 340: free software which everyone can redistribute and change under these terms. 341: 342: To do so, attach the following notices to the program. It is safest 343: to attach them to the start of each source file to most effectively 344: convey the exclusion of warranty; and each file should have at least 345: the "copyright" line and a pointer to where the full notice is found. 346: 347: <one line to give the program's name and a brief idea of what it does.> 348: Copyright (C) <year> <name of author> 349: 350: This program is free software; you can redistribute it and/or modify 351: it under the terms of the GNU General Public License as published by 352: the Free Software Foundation; either version 2 of the License, or 353: (at your option) any later version. 354: 355: This program is distributed in the hope that it will be useful, 356: but WITHOUT ANY WARRANTY; without even the implied warranty of 357: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 358: GNU General Public License for more details. 359: 360: You should have received a copy of the GNU General Public License 361: along with this program; if not, write to the Free Software 362: Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 363: 364: 365: Also add information on how to contact you by electronic and paper mail. 366: 367: If the program is interactive, make it output a short notice like this 368: when it starts in an interactive mode: 369: 370: Gnomovision version 69, Copyright (C) year name of author 371: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 372: This is free software, and you are welcome to redistribute it 373: under certain conditions; type `show c' for details. 374: 375: The hypothetical commands `show w' and `show c' should show the appropriate 376: parts of the General Public License. Of course, the commands you use may 377: be called something other than `show w' and `show c'; they could even be 378: mouse-clicks or menu items--whatever suits your program. 379: 380: You should also get your employer (if you work as a programmer) or your 381: school, if any, to sign a "copyright disclaimer" for the program, if 382: necessary. Here is a sample; alter the names: 383: 384: Yoyodyne, Inc., hereby disclaims all copyright interest in the program 385: `Gnomovision' (which makes passes at compilers) written by James Hacker. 386: 387: <signature of Ty Coon>, 1 April 1989 388: Ty Coon, President of Vice 389: 390: This General Public License does not permit incorporating your program into 391: proprietary programs. If your program is a subroutine library, you may 392: consider it more useful to permit linking proprietary applications with the 393: library. If this is what you want to do, use the GNU Library General 394: Public License instead of this License. 395: </pre> 396:  397: </body> 398: </html>
