By contrast, the GNU General Public 34: License is intended to guarantee your freedom to share and change free 35: software--to make sure the software is free for all its users. This 36: General Public License applies to most of the Free Software 37: Foundation's software and to any other program whose authors commit to 38: using it. (Some other Free Software Foundation software is covered by 39: the GNU Library General Public License instead.) You can apply it to 40: your programs, too. 41: 42: When we speak of free software, we are referring to freedom, not 43: price. Our General Public Licenses are designed to make sure that you 44: have the freedom to distribute copies of free software (and charge for 45: this service if you wish), that you receive source code or can get it 46: if you want it, that you can change the software or use pieces of it 47: in new free programs; and that you know you can do these things. 48: 49: To protect your rights, we need to make restrictions that forbid 50: anyone to deny you these rights or to ask you to surrender the rights. 51: These restrictions translate to certain responsibilities for you if you 52: distribute copies of the software, or if you modify it. 53: 54: For example, if you distribute copies of such a program, whether 55: gratis or for a fee, you must give the recipients all the rights that 56: you have. You must make sure that they, too, receive or can get the 57: source code. And you must show them these terms so they know their 58: rights. 59: 60: We protect your rights with two steps: (1) copyright the software, and 61: (2) offer you this license which gives you legal permission to copy, 62: distribute and/or modify the software. 63: 64: Also, for each author's protection and ours, we want to make certain 65: that everyone understands that there is no warranty for this free 66: software. If the software is modified by someone else and passed on, we 67: want its recipients to know that what they have is not the original, so 68: that any problems introduced by others will not reflect on the original 69: authors' reputations. 70: 71: Finally, any free program is threatened constantly by software 72: patents. We wish to avoid the danger that redistributors of a free 73: program will individually obtain patent licenses, in effect making the 74: program proprietary. To prevent this, we have made it clear that any 75: patent must be licensed for everyone's free use or not licensed at all. 76: 77: The precise terms and conditions for copying, distribution and 78: modification follow. 79: 80: GNU GENERAL PUBLIC LICENSE 81: TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 82: 83: 0. This License applies to any program or other work which contains 84: a notice placed by the copyright holder saying it may be distributed 85: under the terms of this General Public License. The "Program", below, 86: refers to any such program or work, and a "work based on the Program" 87: means either the Program or any derivative work under copyright law: 88: that is to say, a work containing the Program or a portion of it, 89: either verbatim or with modifications and/or translated into another 90: language. (Hereinafter, translation is included without limitation in 91: the term "modification".) Each licensee is addressed as "you". 92: 93: Activities other than copying, distribution and modification are not 94: covered by this License; they are outside its scope. The act of 95: running the Program is not restricted, and the output from the Program 96: is covered only if its contents constitute a work based on the 97: Program (independent of having been made by running the Program). 98: Whether that is true depends on what the Program does. 99: 100: 1. You may copy and distribute verbatim copies of the Program's 101: source code as you receive it, in any medium, provided that you 102: conspicuously and appropriately publish on each copy an appropriate 103: copyright notice and disclaimer of warranty; keep intact all the 104: notices that refer to this License and to the absence of any warranty; 105: and give any other recipients of the Program a copy of this License 106: along with the Program. 107: 108: You may charge a fee for the physical act of transferring a copy, and 109: you may at your option offer warranty protection in exchange for a fee. 110: 111: 2. You may modify your copy or copies of the Program or any portion 112: of it, thus forming a work based on the Program, and copy and 113: distribute such modifications or work under the terms of Section 1 114: above, provided that you also meet all of these conditions: 115: 116: a) You must cause the modified files to carry prominent notices 117: stating that you changed the files and the date of any change. 118: 119: b) You must cause any work that you distribute or publish, that in 120: whole or in part contains or is derived from the Program or any 121: part thereof, to be licensed as a whole at no charge to all third 122: parties under the terms of this License. 123: 124: c) If the modified program normally reads commands interactively 125: when run, you must cause it, when started running for such 126: interactive use in the most ordinary way, to print or display an 127: announcement including an appropriate copyright notice and a 128: notice that there is no warranty (or else, saying that you provide 129: a warranty) and that users may redistribute the program under 130: these conditions, and telling the user how to view a copy of this 131: License. (Exception: if the Program itself is interactive but 132: does not normally print such an announcement, your work based on 133: the Program is not required to print an announcement.) 134: 135: These requirements apply to the modified work as a whole. If 136: identifiable sections of that work are not derived from the Program, 137: and can be reasonably considered independent and separate works in 138: themselves, then this License, and its terms, do not apply to those 139: sections when you distribute them as separate works. But when you 140: distribute the same sections as part of a whole which is a work based 141: on the Program, the distribution of the whole must be on the terms of 142: this License, whose permissions for other licensees extend to the 143: entire whole, and thus to each and every part regardless of who wrote it. 144: 145: Thus, it is not the intent of this section to claim rights or contest 146: your rights to work written entirely by you; rather, the intent is to 147: exercise the right to control the distribution of derivative or 148: collective works based on the Program. 149: 150: In addition, mere aggregation of another work not based on the Program 151: with the Program (or with a work based on the Program) on a volume of 152: a storage or distribution medium does not bring the other work under 153: the scope of this License. 154: 155: 3. You may copy and distribute the Program (or a work based on it, 156: under Section 2) in object code or executable form under the terms of 157: Sections 1 and 2 above provided that you also do one of the following: 158: 159: a) Accompany it with the complete corresponding machine-readable 160: source code, which must be distributed under the terms of Sections 161: 1 and 2 above on a medium customarily used for software interchange; or, 162: 163: b) Accompany it with a written offer, valid for at least three 164: years, to give any third party, for a charge no more than your 165: cost of physically performing source distribution, a complete 166: machine-readable copy of the corresponding source code, to be 167: distributed under the terms of Sections 1 and 2 above on a medium 168: customarily used for software interchange; or, 169: 170: c) Accompany it with the information you received as to the offer 171: to distribute corresponding source code. (This alternative is 172: allowed only for noncommercial distribution and only if you 173: received the program in object code or executable form with such 174: an offer, in accord with Subsection b above.) 175: 176: The source code for a work means the preferred form of the work for 177: making modifications to it. For an executable work, complete source 178: code means all the source code for all modules it contains, plus any 179: associated interface definition files, plus the scripts used to 180: control compilation and installation of the executable. However, as a 181: special exception, the source code distributed need not include 182: anything that is normally distributed (in either source or binary 183: form) with the major components (compiler, kernel, and so on) of the 184: operating system on which the executable runs, unless that component 185: itself accompanies the executable. 186: 187: If distribution of executable or object code is made by offering 188: access to copy from a designated place, then offering equivalent 189: access to copy the source code from the same place counts as 190: distribution of the source code, even though third parties are not 191: compelled to copy the source along with the object code. 192: 193: 4. You may not copy, modify, sublicense, or distribute the Program 194: except as expressly provided under this License. Any attempt 195: otherwise to copy, modify, sublicense or distribute the Program is 196: void, and will automatically terminate your rights under this License. 197: However, parties who have received copies, or rights, from you under 198: this License will not have their licenses terminated so long as such 199: parties remain in full compliance. 200: 201: 5. You are not required to accept this License, since you have not 202: signed it. However, nothing else grants you permission to modify or 203: distribute the Program or its derivative works. These actions are 204: prohibited by law if you do not accept this License. Therefore, by 205: modifying or distributing the Program (or any work based on the 206: Program), you indicate your acceptance of this License to do so, and 207: all its terms and conditions for copying, distributing or modifying 208: the Program or works based on it. 209: 210: 6. Each time you redistribute the Program (or any work based on the 211: Program), the recipient automatically receives a license from the 212: original licensor to copy, distribute or modify the Program subject to 213: these terms and conditions. You may not impose any further 214: restrictions on the recipients' exercise of the rights granted herein. 215: You are not responsible for enforcing compliance by third parties to 216: this License. 217: 218: 7. If, as a consequence of a court judgment or allegation of patent 219: infringement or for any other reason (not limited to patent issues), 220: conditions are imposed on you (whether by court order, agreement or 221: otherwise) that contradict the conditions of this License, they do not 222: excuse you from the conditions of this License. If you cannot 223: distribute so as to satisfy simultaneously your obligations under this 224: License and any other pertinent obligations, then as a consequence you 225: may not distribute the Program at all. For example, if a patent 226: license would not permit royalty-free redistribution of the Program by 227: all those who receive copies directly or indirectly through you, then 228: the only way you could satisfy both it and this License would be to 229: refrain entirely from distribution of the Program. 230: 231: If any portion of this section is held invalid or unenforceable under 232: any particular circumstance, the balance of the section is intended to 233: apply and the section as a whole is intended to apply in other 234: circumstances. 235: 236: It is not the purpose of this section to induce you to infringe any 237: patents or other property right claims or to contest validity of any 238: such claims; this section has the sole purpose of protecting the 239: integrity of the free software distribution system, which is 240: implemented by public license practices. Many people have made 241: generous contributions to the wide range of software distributed 242: through that system in reliance on consistent application of that 243: system; it is up to the author/donor to decide if he or she is willing 244: to distribute software through any other system and a licensee cannot 245: impose that choice. 246: 247: This section is intended to make thoroughly clear what is believed to 248: be a consequence of the rest of this License. 249: 250: 8. If the distribution and/or use of the Program is restricted in 251: certain countries either by patents or by copyrighted interfaces, the 252: original copyright holder who places the Program under this License 253: may add an explicit geographical distribution limitation excluding 254: those countries, so that distribution is permitted only in or among 255: countries not thus excluded. In such case, this License incorporates 256: the limitation as if written in the body of this License. 257: 258: 9. The Free Software Foundation may publish revised and/or new versions 259: of the General Public License from time to time. Such new versions will 260: be similar in spirit to the present version, but may differ in detail to 261: address new problems or concerns. 262: 263: Each version is given a distinguishing version number. If the Program 264: specifies a version number of this License which applies to it and "any 265: later version", you have the option of following the terms and conditions 266: either of that version or of any later version published by the Free 267: Software Foundation. If the Program does not specify a version number of 268: this License, you may choose any version ever published by the Free Software 269: Foundation. 270: 271: 10. If you wish to incorporate parts of the Program into other free 272: programs whose distribution conditions are different, write to the author 273: to ask for permission. For software which is copyrighted by the Free 274: Software Foundation, write to the Free Software Foundation; we sometimes 275: make exceptions for this. Our decision will be guided by the two goals 276: of preserving the free status of all derivatives of our free software and 277: of promoting the sharing and reuse of software generally. 278: 279: NO WARRANTY 280: 281: 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 282: FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 283: OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 284: PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 285: OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 286: MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 287: TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 288: PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 289: REPAIR OR CORRECTION. 290: 291: 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 292: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 293: REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 294: INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 295: OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 296: TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 297: YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 298: PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 299: POSSIBILITY OF SUCH DAMAGES. 300: 301: END OF TERMS AND CONDITIONS 302: 303: How to Apply These Terms to Your New Programs 304: 305: If you develop a new program, and you want it to be of the greatest 306: possible use to the public, the best way to achieve this is to make it 307: free software which everyone can redistribute and change under these terms. 308: 309: To do so, attach the following notices to the program. It is safest 310: to attach them to the start of each source file to most effectively 311: convey the exclusion of warranty; and each file should have at least 312: the "copyright" line and a pointer to where the full notice is found. 313: 314: <one line to give the program's name and a brief idea of what it does.> 315: Copyright (C) <year> <name of author> 316: 317: This program is free software; you can redistribute it and/or modify 318: it under the terms of the GNU General Public License as published by 319: the Free Software Foundation; either version 2 of the License, or 320: (at your option) any later version. 321: 322: This program is distributed in the hope that it will be useful, 323: but WITHOUT ANY WARRANTY; without even the implied warranty of 324: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 325: GNU General Public License for more details. 326: 327: You should have received a copy of the GNU General Public License 328: along with this program; if not, write to the Free Software 329: Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 330: 331: 332: Also add information on how to contact you by electronic and paper mail. 333: 334: If the program is interactive, make it output a short notice like this 335: when it starts in an interactive mode: 336: 337: Gnomovision version 69, Copyright (C) year name of author 338: Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 339: This is free software, and you are welcome to redistribute it 340: under certain conditions; type `show c' for details. 341: 342: The hypothetical commands `show w' and `show c' should show the appropriate 343: parts of the General Public License. Of course, the commands you use may 344: be called something other than `show w' and `show c'; they could even be 345: mouse-clicks or menu items--whatever suits your program. 346: 347: You should also get your employer (if you work as a programmer) or your 348: school, if any, to sign a "copyright disclaimer" for the program, if 349: necessary. Here is a sample; alter the names: 350: 351: Yoyodyne, Inc., hereby disclaims all copyright interest in the program 352: `Gnomovision' (which makes passes at compilers) written by James Hacker. 353: 354: <signature of Ty Coon>, 1 April 1989 355: Ty Coon, President of Vice 356: 357: This General Public License does not permit incorporating your program into 358: proprietary programs. If your program is a subroutine library, you may 359: consider it more useful to permit linking proprietary applications with the 360: library. If this is what you want to do, use the GNU Library General 361: Public License instead of this License. 362: </pre> 363:  364: </body> 365: </html>
