By contrast, the GNU General Public 13*42ff0bbcSThomas HuthLicense is intended to guarantee your freedom to share and change free 14*42ff0bbcSThomas Huthsoftware--to make sure the software is free for all its users. This 15*42ff0bbcSThomas HuthGeneral Public License applies to most of the Free Software 16*42ff0bbcSThomas HuthFoundation's software and to any other program whose authors commit to 17*42ff0bbcSThomas Huthusing it. (Some other Free Software Foundation software is covered by 18*42ff0bbcSThomas Huththe GNU Lesser General Public License instead.) You can apply it to 19*42ff0bbcSThomas Huthyour programs, too. 20*42ff0bbcSThomas Huth 21*42ff0bbcSThomas Huth When we speak of free software, we are referring to freedom, not 22*42ff0bbcSThomas Huthprice. Our General Public Licenses are designed to make sure that you 23*42ff0bbcSThomas Huthhave the freedom to distribute copies of free software (and charge for 24*42ff0bbcSThomas Huththis service if you wish), that you receive source code or can get it 25*42ff0bbcSThomas Huthif you want it, that you can change the software or use pieces of it 26*42ff0bbcSThomas Huthin new free programs; and that you know you can do these things. 27*42ff0bbcSThomas Huth 28*42ff0bbcSThomas Huth To protect your rights, we need to make restrictions that forbid 29*42ff0bbcSThomas Huthanyone to deny you these rights or to ask you to surrender the rights. 30*42ff0bbcSThomas HuthThese restrictions translate to certain responsibilities for you if you 31*42ff0bbcSThomas Huthdistribute copies of the software, or if you modify it. 32*42ff0bbcSThomas Huth 33*42ff0bbcSThomas Huth For example, if you distribute copies of such a program, whether 34*42ff0bbcSThomas Huthgratis or for a fee, you must give the recipients all the rights that 35*42ff0bbcSThomas Huthyou have. You must make sure that they, too, receive or can get the 36*42ff0bbcSThomas Huthsource code. And you must show them these terms so they know their 37*42ff0bbcSThomas Huthrights. 38*42ff0bbcSThomas Huth 39*42ff0bbcSThomas Huth We protect your rights with two steps: (1) copyright the software, and 40*42ff0bbcSThomas Huth(2) offer you this license which gives you legal permission to copy, 41*42ff0bbcSThomas Huthdistribute and/or modify the software. 42*42ff0bbcSThomas Huth 43*42ff0bbcSThomas Huth Also, for each author's protection and ours, we want to make certain 44*42ff0bbcSThomas Huththat everyone understands that there is no warranty for this free 45*42ff0bbcSThomas Huthsoftware. If the software is modified by someone else and passed on, we 46*42ff0bbcSThomas Huthwant its recipients to know that what they have is not the original, so 47*42ff0bbcSThomas Huththat any problems introduced by others will not reflect on the original 48*42ff0bbcSThomas Huthauthors' reputations. 49*42ff0bbcSThomas Huth 50*42ff0bbcSThomas Huth Finally, any free program is threatened constantly by software 51*42ff0bbcSThomas Huthpatents. We wish to avoid the danger that redistributors of a free 52*42ff0bbcSThomas Huthprogram will individually obtain patent licenses, in effect making the 53*42ff0bbcSThomas Huthprogram proprietary. To prevent this, we have made it clear that any 54*42ff0bbcSThomas Huthpatent must be licensed for everyone's free use or not licensed at all. 55*42ff0bbcSThomas Huth 56*42ff0bbcSThomas Huth The precise terms and conditions for copying, distribution and 57*42ff0bbcSThomas Huthmodification follow. 58*42ff0bbcSThomas Huth 59*42ff0bbcSThomas Huth GNU GENERAL PUBLIC LICENSE 60*42ff0bbcSThomas Huth TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61*42ff0bbcSThomas Huth 62*42ff0bbcSThomas Huth 0. This License applies to any program or other work which contains 63*42ff0bbcSThomas Hutha notice placed by the copyright holder saying it may be distributed 64*42ff0bbcSThomas Huthunder the terms of this General Public License. The "Program", below, 65*42ff0bbcSThomas Huthrefers to any such program or work, and a "work based on the Program" 66*42ff0bbcSThomas Huthmeans either the Program or any derivative work under copyright law: 67*42ff0bbcSThomas Huththat is to say, a work containing the Program or a portion of it, 68*42ff0bbcSThomas Hutheither verbatim or with modifications and/or translated into another 69*42ff0bbcSThomas Huthlanguage. (Hereinafter, translation is included without limitation in 70*42ff0bbcSThomas Huththe term "modification".) Each licensee is addressed as "you". 71*42ff0bbcSThomas Huth 72*42ff0bbcSThomas HuthActivities other than copying, distribution and modification are not 73*42ff0bbcSThomas Huthcovered by this License; they are outside its scope. The act of 74*42ff0bbcSThomas Huthrunning the Program is not restricted, and the output from the Program 75*42ff0bbcSThomas Huthis covered only if its contents constitute a work based on the 76*42ff0bbcSThomas HuthProgram (independent of having been made by running the Program). 77*42ff0bbcSThomas HuthWhether that is true depends on what the Program does. 78*42ff0bbcSThomas Huth 79*42ff0bbcSThomas Huth 1. You may copy and distribute verbatim copies of the Program's 80*42ff0bbcSThomas Huthsource code as you receive it, in any medium, provided that you 81*42ff0bbcSThomas Huthconspicuously and appropriately publish on each copy an appropriate 82*42ff0bbcSThomas Huthcopyright notice and disclaimer of warranty; keep intact all the 83*42ff0bbcSThomas Huthnotices that refer to this License and to the absence of any warranty; 84*42ff0bbcSThomas Huthand give any other recipients of the Program a copy of this License 85*42ff0bbcSThomas Huthalong with the Program. 86*42ff0bbcSThomas Huth 87*42ff0bbcSThomas HuthYou may charge a fee for the physical act of transferring a copy, and 88*42ff0bbcSThomas Huthyou may at your option offer warranty protection in exchange for a fee. 89*42ff0bbcSThomas Huth 90*42ff0bbcSThomas Huth 2. You may modify your copy or copies of the Program or any portion 91*42ff0bbcSThomas Huthof it, thus forming a work based on the Program, and copy and 92*42ff0bbcSThomas Huthdistribute such modifications or work under the terms of Section 1 93*42ff0bbcSThomas Huthabove, provided that you also meet all of these conditions: 94*42ff0bbcSThomas Huth 95*42ff0bbcSThomas Huth a) You must cause the modified files to carry prominent notices 96*42ff0bbcSThomas Huth stating that you changed the files and the date of any change. 97*42ff0bbcSThomas Huth 98*42ff0bbcSThomas Huth b) You must cause any work that you distribute or publish, that in 99*42ff0bbcSThomas Huth whole or in part contains or is derived from the Program or any 100*42ff0bbcSThomas Huth part thereof, to be licensed as a whole at no charge to all third 101*42ff0bbcSThomas Huth parties under the terms of this License. 102*42ff0bbcSThomas Huth 103*42ff0bbcSThomas Huth c) If the modified program normally reads commands interactively 104*42ff0bbcSThomas Huth when run, you must cause it, when started running for such 105*42ff0bbcSThomas Huth interactive use in the most ordinary way, to print or display an 106*42ff0bbcSThomas Huth announcement including an appropriate copyright notice and a 107*42ff0bbcSThomas Huth notice that there is no warranty (or else, saying that you provide 108*42ff0bbcSThomas Huth a warranty) and that users may redistribute the program under 109*42ff0bbcSThomas Huth these conditions, and telling the user how to view a copy of this 110*42ff0bbcSThomas Huth License. (Exception: if the Program itself is interactive but 111*42ff0bbcSThomas Huth does not normally print such an announcement, your work based on 112*42ff0bbcSThomas Huth the Program is not required to print an announcement.) 113*42ff0bbcSThomas Huth 114*42ff0bbcSThomas HuthThese requirements apply to the modified work as a whole. If 115*42ff0bbcSThomas Huthidentifiable sections of that work are not derived from the Program, 116*42ff0bbcSThomas Huthand can be reasonably considered independent and separate works in 117*42ff0bbcSThomas Huththemselves, then this License, and its terms, do not apply to those 118*42ff0bbcSThomas Huthsections when you distribute them as separate works. But when you 119*42ff0bbcSThomas Huthdistribute the same sections as part of a whole which is a work based 120*42ff0bbcSThomas Huthon the Program, the distribution of the whole must be on the terms of 121*42ff0bbcSThomas Huththis License, whose permissions for other licensees extend to the 122*42ff0bbcSThomas Huthentire whole, and thus to each and every part regardless of who wrote it. 123*42ff0bbcSThomas Huth 124*42ff0bbcSThomas HuthThus, it is not the intent of this section to claim rights or contest 125*42ff0bbcSThomas Huthyour rights to work written entirely by you; rather, the intent is to 126*42ff0bbcSThomas Huthexercise the right to control the distribution of derivative or 127*42ff0bbcSThomas Huthcollective works based on the Program. 128*42ff0bbcSThomas Huth 129*42ff0bbcSThomas HuthIn addition, mere aggregation of another work not based on the Program 130*42ff0bbcSThomas Huthwith the Program (or with a work based on the Program) on a volume of 131*42ff0bbcSThomas Hutha storage or distribution medium does not bring the other work under 132*42ff0bbcSThomas Huththe scope of this License. 133*42ff0bbcSThomas Huth 134*42ff0bbcSThomas Huth 3. You may copy and distribute the Program (or a work based on it, 135*42ff0bbcSThomas Huthunder Section 2) in object code or executable form under the terms of 136*42ff0bbcSThomas HuthSections 1 and 2 above provided that you also do one of the following: 137*42ff0bbcSThomas Huth 138*42ff0bbcSThomas Huth a) Accompany it with the complete corresponding machine-readable 139*42ff0bbcSThomas Huth source code, which must be distributed under the terms of Sections 140*42ff0bbcSThomas Huth 1 and 2 above on a medium customarily used for software interchange; or, 141*42ff0bbcSThomas Huth 142*42ff0bbcSThomas Huth b) Accompany it with a written offer, valid for at least three 143*42ff0bbcSThomas Huth years, to give any third party, for a charge no more than your 144*42ff0bbcSThomas Huth cost of physically performing source distribution, a complete 145*42ff0bbcSThomas Huth machine-readable copy of the corresponding source code, to be 146*42ff0bbcSThomas Huth distributed under the terms of Sections 1 and 2 above on a medium 147*42ff0bbcSThomas Huth customarily used for software interchange; or, 148*42ff0bbcSThomas Huth 149*42ff0bbcSThomas Huth c) Accompany it with the information you received as to the offer 150*42ff0bbcSThomas Huth to distribute corresponding source code. (This alternative is 151*42ff0bbcSThomas Huth allowed only for noncommercial distribution and only if you 152*42ff0bbcSThomas Huth received the program in object code or executable form with such 153*42ff0bbcSThomas Huth an offer, in accord with Subsection b above.) 154*42ff0bbcSThomas Huth 155*42ff0bbcSThomas HuthThe source code for a work means the preferred form of the work for 156*42ff0bbcSThomas Huthmaking modifications to it. For an executable work, complete source 157*42ff0bbcSThomas Huthcode means all the source code for all modules it contains, plus any 158*42ff0bbcSThomas Huthassociated interface definition files, plus the scripts used to 159*42ff0bbcSThomas Huthcontrol compilation and installation of the executable. However, as a 160*42ff0bbcSThomas Huthspecial exception, the source code distributed need not include 161*42ff0bbcSThomas Huthanything that is normally distributed (in either source or binary 162*42ff0bbcSThomas Huthform) with the major components (compiler, kernel, and so on) of the 163*42ff0bbcSThomas Huthoperating system on which the executable runs, unless that component 164*42ff0bbcSThomas Huthitself accompanies the executable. 165*42ff0bbcSThomas Huth 166*42ff0bbcSThomas HuthIf distribution of executable or object code is made by offering 167*42ff0bbcSThomas Huthaccess to copy from a designated place, then offering equivalent 168*42ff0bbcSThomas Huthaccess to copy the source code from the same place counts as 169*42ff0bbcSThomas Huthdistribution of the source code, even though third parties are not 170*42ff0bbcSThomas Huthcompelled to copy the source along with the object code. 171*42ff0bbcSThomas Huth 172*42ff0bbcSThomas Huth 4. You may not copy, modify, sublicense, or distribute the Program 173*42ff0bbcSThomas Huthexcept as expressly provided under this License. Any attempt 174*42ff0bbcSThomas Huthotherwise to copy, modify, sublicense or distribute the Program is 175*42ff0bbcSThomas Huthvoid, and will automatically terminate your rights under this License. 176*42ff0bbcSThomas HuthHowever, parties who have received copies, or rights, from you under 177*42ff0bbcSThomas Huththis License will not have their licenses terminated so long as such 178*42ff0bbcSThomas Huthparties remain in full compliance. 179*42ff0bbcSThomas Huth 180*42ff0bbcSThomas Huth 5. You are not required to accept this License, since you have not 181*42ff0bbcSThomas Huthsigned it. However, nothing else grants you permission to modify or 182*42ff0bbcSThomas Huthdistribute the Program or its derivative works. These actions are 183*42ff0bbcSThomas Huthprohibited by law if you do not accept this License. Therefore, by 184*42ff0bbcSThomas Huthmodifying or distributing the Program (or any work based on the 185*42ff0bbcSThomas HuthProgram), you indicate your acceptance of this License to do so, and 186*42ff0bbcSThomas Huthall its terms and conditions for copying, distributing or modifying 187*42ff0bbcSThomas Huththe Program or works based on it. 188*42ff0bbcSThomas Huth 189*42ff0bbcSThomas Huth 6. Each time you redistribute the Program (or any work based on the 190*42ff0bbcSThomas HuthProgram), the recipient automatically receives a license from the 191*42ff0bbcSThomas Huthoriginal licensor to copy, distribute or modify the Program subject to 192*42ff0bbcSThomas Huththese terms and conditions. You may not impose any further 193*42ff0bbcSThomas Huthrestrictions on the recipients' exercise of the rights granted herein. 194*42ff0bbcSThomas HuthYou are not responsible for enforcing compliance by third parties to 195*42ff0bbcSThomas Huththis License. 196*42ff0bbcSThomas Huth 197*42ff0bbcSThomas Huth 7. If, as a consequence of a court judgment or allegation of patent 198*42ff0bbcSThomas Huthinfringement or for any other reason (not limited to patent issues), 199*42ff0bbcSThomas Huthconditions are imposed on you (whether by court order, agreement or 200*42ff0bbcSThomas Huthotherwise) that contradict the conditions of this License, they do not 201*42ff0bbcSThomas Huthexcuse you from the conditions of this License. If you cannot 202*42ff0bbcSThomas Huthdistribute so as to satisfy simultaneously your obligations under this 203*42ff0bbcSThomas HuthLicense and any other pertinent obligations, then as a consequence you 204*42ff0bbcSThomas Huthmay not distribute the Program at all. For example, if a patent 205*42ff0bbcSThomas Huthlicense would not permit royalty-free redistribution of the Program by 206*42ff0bbcSThomas Huthall those who receive copies directly or indirectly through you, then 207*42ff0bbcSThomas Huththe only way you could satisfy both it and this License would be to 208*42ff0bbcSThomas Huthrefrain entirely from distribution of the Program. 209*42ff0bbcSThomas Huth 210*42ff0bbcSThomas HuthIf any portion of this section is held invalid or unenforceable under 211*42ff0bbcSThomas Huthany particular circumstance, the balance of the section is intended to 212*42ff0bbcSThomas Huthapply and the section as a whole is intended to apply in other 213*42ff0bbcSThomas Huthcircumstances. 214*42ff0bbcSThomas Huth 215*42ff0bbcSThomas HuthIt is not the purpose of this section to induce you to infringe any 216*42ff0bbcSThomas Huthpatents or other property right claims or to contest validity of any 217*42ff0bbcSThomas Huthsuch claims; this section has the sole purpose of protecting the 218*42ff0bbcSThomas Huthintegrity of the free software distribution system, which is 219*42ff0bbcSThomas Huthimplemented by public license practices. Many people have made 220*42ff0bbcSThomas Huthgenerous contributions to the wide range of software distributed 221*42ff0bbcSThomas Huththrough that system in reliance on consistent application of that 222*42ff0bbcSThomas Huthsystem; it is up to the author/donor to decide if he or she is willing 223*42ff0bbcSThomas Huthto distribute software through any other system and a licensee cannot 224*42ff0bbcSThomas Huthimpose that choice. 225*42ff0bbcSThomas Huth 226*42ff0bbcSThomas HuthThis section is intended to make thoroughly clear what is believed to 227*42ff0bbcSThomas Huthbe a consequence of the rest of this License. 228*42ff0bbcSThomas Huth 229*42ff0bbcSThomas Huth 8. If the distribution and/or use of the Program is restricted in 230*42ff0bbcSThomas Huthcertain countries either by patents or by copyrighted interfaces, the 231*42ff0bbcSThomas Huthoriginal copyright holder who places the Program under this License 232*42ff0bbcSThomas Huthmay add an explicit geographical distribution limitation excluding 233*42ff0bbcSThomas Huththose countries, so that distribution is permitted only in or among 234*42ff0bbcSThomas Huthcountries not thus excluded. In such case, this License incorporates 235*42ff0bbcSThomas Huththe limitation as if written in the body of this License. 236*42ff0bbcSThomas Huth 237*42ff0bbcSThomas Huth 9. The Free Software Foundation may publish revised and/or new versions 238*42ff0bbcSThomas Huthof the General Public License from time to time. Such new versions will 239*42ff0bbcSThomas Huthbe similar in spirit to the present version, but may differ in detail to 240*42ff0bbcSThomas Huthaddress new problems or concerns. 241*42ff0bbcSThomas Huth 242*42ff0bbcSThomas HuthEach version is given a distinguishing version number. If the Program 243*42ff0bbcSThomas Huthspecifies a version number of this License which applies to it and "any 244*42ff0bbcSThomas Huthlater version", you have the option of following the terms and conditions 245*42ff0bbcSThomas Hutheither of that version or of any later version published by the Free 246*42ff0bbcSThomas HuthSoftware Foundation. If the Program does not specify a version number of 247*42ff0bbcSThomas Huththis License, you may choose any version ever published by the Free Software 248*42ff0bbcSThomas HuthFoundation. 249*42ff0bbcSThomas Huth 250*42ff0bbcSThomas Huth 10. If you wish to incorporate parts of the Program into other free 251*42ff0bbcSThomas Huthprograms whose distribution conditions are different, write to the author 252*42ff0bbcSThomas Huthto ask for permission. For software which is copyrighted by the Free 253*42ff0bbcSThomas HuthSoftware Foundation, write to the Free Software Foundation; we sometimes 254*42ff0bbcSThomas Huthmake exceptions for this. Our decision will be guided by the two goals 255*42ff0bbcSThomas Huthof preserving the free status of all derivatives of our free software and 256*42ff0bbcSThomas Huthof promoting the sharing and reuse of software generally. 257*42ff0bbcSThomas Huth 258*42ff0bbcSThomas Huth NO WARRANTY 259*42ff0bbcSThomas Huth 260*42ff0bbcSThomas Huth 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261*42ff0bbcSThomas HuthFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262*42ff0bbcSThomas HuthOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263*42ff0bbcSThomas HuthPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264*42ff0bbcSThomas HuthOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265*42ff0bbcSThomas HuthMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 266*42ff0bbcSThomas HuthTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 267*42ff0bbcSThomas HuthPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 268*42ff0bbcSThomas HuthREPAIR OR CORRECTION. 269*42ff0bbcSThomas Huth 270*42ff0bbcSThomas Huth 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 271*42ff0bbcSThomas HuthWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 272*42ff0bbcSThomas HuthREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 273*42ff0bbcSThomas HuthINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 274*42ff0bbcSThomas HuthOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 275*42ff0bbcSThomas HuthTO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 276*42ff0bbcSThomas HuthYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 277*42ff0bbcSThomas HuthPROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 278*42ff0bbcSThomas HuthPOSSIBILITY OF SUCH DAMAGES. 279*42ff0bbcSThomas Huth 280*42ff0bbcSThomas Huth END OF TERMS AND CONDITIONS 281*42ff0bbcSThomas Huth 282*42ff0bbcSThomas Huth How to Apply These Terms to Your New Programs 283*42ff0bbcSThomas Huth 284*42ff0bbcSThomas Huth If you develop a new program, and you want it to be of the greatest 285*42ff0bbcSThomas Huthpossible use to the public, the best way to achieve this is to make it 286*42ff0bbcSThomas Huthfree software which everyone can redistribute and change under these terms. 287*42ff0bbcSThomas Huth 288*42ff0bbcSThomas Huth To do so, attach the following notices to the program. It is safest 289*42ff0bbcSThomas Huthto attach them to the start of each source file to most effectively 290*42ff0bbcSThomas Huthconvey the exclusion of warranty; and each file should have at least 291*42ff0bbcSThomas Huththe "copyright" line and a pointer to where the full notice is found. 292*42ff0bbcSThomas Huth 293*42ff0bbcSThomas Huth <one line to give the program's name and a brief idea of what it does.> 294*42ff0bbcSThomas Huth Copyright (C) <year> <name of author> 295*42ff0bbcSThomas Huth 296*42ff0bbcSThomas Huth This program is free software; you can redistribute it and/or modify 297*42ff0bbcSThomas Huth it under the terms of the GNU General Public License as published by 298*42ff0bbcSThomas Huth the Free Software Foundation; either version 2 of the License, or 299*42ff0bbcSThomas Huth (at your option) any later version. 300*42ff0bbcSThomas Huth 301*42ff0bbcSThomas Huth This program is distributed in the hope that it will be useful, 302*42ff0bbcSThomas Huth but WITHOUT ANY WARRANTY; without even the implied warranty of 303*42ff0bbcSThomas Huth MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
