1*ced89be4SMichael Große GNU GENERAL PUBLIC LICENSE 2*ced89be4SMichael Große Version 2, June 1991 3*ced89be4SMichael Große 4*ced89be4SMichael Große Copyright (C) 1989, 1991 Free Software Foundation, Inc., 5*ced89be4SMichael Große 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA 6*ced89be4SMichael Große Everyone is permitted to copy and distribute verbatim copies 7*ced89be4SMichael Große of this license document, but changing it is not allowed. 8*ced89be4SMichael Große 9*ced89be4SMichael Große Preamble 10*ced89be4SMichael Große 11*ced89be4SMichael Große The licenses for most software are designed to take away your 12*ced89be4SMichael Großefreedom to share and change it. By contrast, the GNU General Public 13*ced89be4SMichael GroßeLicense is intended to guarantee your freedom to share and change free 14*ced89be4SMichael Großesoftware--to make sure the software is free for all its users. This 15*ced89be4SMichael GroßeGeneral Public License applies to most of the Free Software 16*ced89be4SMichael GroßeFoundation's software and to any other program whose authors commit to 17*ced89be4SMichael Großeusing it. (Some other Free Software Foundation software is covered by 18*ced89be4SMichael Großethe GNU Lesser General Public License instead.) You can apply it to 19*ced89be4SMichael Großeyour programs, too. 20*ced89be4SMichael Große 21*ced89be4SMichael Große When we speak of free software, we are referring to freedom, not 22*ced89be4SMichael Großeprice. Our General Public Licenses are designed to make sure that you 23*ced89be4SMichael Großehave the freedom to distribute copies of free software (and charge for 24*ced89be4SMichael Großethis service if you wish), that you receive source code or can get it 25*ced89be4SMichael Großeif you want it, that you can change the software or use pieces of it 26*ced89be4SMichael Großein new free programs; and that you know you can do these things. 27*ced89be4SMichael Große 28*ced89be4SMichael Große To protect your rights, we need to make restrictions that forbid 29*ced89be4SMichael Großeanyone to deny you these rights or to ask you to surrender the rights. 30*ced89be4SMichael GroßeThese restrictions translate to certain responsibilities for you if you 31*ced89be4SMichael Großedistribute copies of the software, or if you modify it. 32*ced89be4SMichael Große 33*ced89be4SMichael Große For example, if you distribute copies of such a program, whether 34*ced89be4SMichael Großegratis or for a fee, you must give the recipients all the rights that 35*ced89be4SMichael Großeyou have. You must make sure that they, too, receive or can get the 36*ced89be4SMichael Großesource code. And you must show them these terms so they know their 37*ced89be4SMichael Großerights. 38*ced89be4SMichael Große 39*ced89be4SMichael Große We protect your rights with two steps: (1) copyright the software, and 40*ced89be4SMichael Große(2) offer you this license which gives you legal permission to copy, 41*ced89be4SMichael Großedistribute and/or modify the software. 42*ced89be4SMichael Große 43*ced89be4SMichael Große Also, for each author's protection and ours, we want to make certain 44*ced89be4SMichael Großethat everyone understands that there is no warranty for this free 45*ced89be4SMichael Großesoftware. If the software is modified by someone else and passed on, we 46*ced89be4SMichael Großewant its recipients to know that what they have is not the original, so 47*ced89be4SMichael Großethat any problems introduced by others will not reflect on the original 48*ced89be4SMichael Großeauthors' reputations. 49*ced89be4SMichael Große 50*ced89be4SMichael Große Finally, any free program is threatened constantly by software 51*ced89be4SMichael Großepatents. We wish to avoid the danger that redistributors of a free 52*ced89be4SMichael Großeprogram will individually obtain patent licenses, in effect making the 53*ced89be4SMichael Großeprogram proprietary. To prevent this, we have made it clear that any 54*ced89be4SMichael Großepatent must be licensed for everyone's free use or not licensed at all. 55*ced89be4SMichael Große 56*ced89be4SMichael Große The precise terms and conditions for copying, distribution and 57*ced89be4SMichael Großemodification follow. 58*ced89be4SMichael Große 59*ced89be4SMichael Große GNU GENERAL PUBLIC LICENSE 60*ced89be4SMichael Große TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61*ced89be4SMichael Große 62*ced89be4SMichael Große 0. This License applies to any program or other work which contains 63*ced89be4SMichael Großea notice placed by the copyright holder saying it may be distributed 64*ced89be4SMichael Großeunder the terms of this General Public License. The "Program", below, 65*ced89be4SMichael Großerefers to any such program or work, and a "work based on the Program" 66*ced89be4SMichael Großemeans either the Program or any derivative work under copyright law: 67*ced89be4SMichael Großethat is to say, a work containing the Program or a portion of it, 68*ced89be4SMichael Großeeither verbatim or with modifications and/or translated into another 69*ced89be4SMichael Großelanguage. (Hereinafter, translation is included without limitation in 70*ced89be4SMichael Großethe term "modification".) Each licensee is addressed as "you". 71*ced89be4SMichael Große 72*ced89be4SMichael GroßeActivities other than copying, distribution and modification are not 73*ced89be4SMichael Großecovered by this License; they are outside its scope. The act of 74*ced89be4SMichael Großerunning the Program is not restricted, and the output from the Program 75*ced89be4SMichael Großeis covered only if its contents constitute a work based on the 76*ced89be4SMichael GroßeProgram (independent of having been made by running the Program). 77*ced89be4SMichael GroßeWhether that is true depends on what the Program does. 78*ced89be4SMichael Große 79*ced89be4SMichael Große 1. You may copy and distribute verbatim copies of the Program's 80*ced89be4SMichael Großesource code as you receive it, in any medium, provided that you 81*ced89be4SMichael Großeconspicuously and appropriately publish on each copy an appropriate 82*ced89be4SMichael Großecopyright notice and disclaimer of warranty; keep intact all the 83*ced89be4SMichael Großenotices that refer to this License and to the absence of any warranty; 84*ced89be4SMichael Großeand give any other recipients of the Program a copy of this License 85*ced89be4SMichael Großealong with the Program. 86*ced89be4SMichael Große 87*ced89be4SMichael GroßeYou may charge a fee for the physical act of transferring a copy, and 88*ced89be4SMichael Großeyou may at your option offer warranty protection in exchange for a fee. 89*ced89be4SMichael Große 90*ced89be4SMichael Große 2. You may modify your copy or copies of the Program or any portion 91*ced89be4SMichael Großeof it, thus forming a work based on the Program, and copy and 92*ced89be4SMichael Großedistribute such modifications or work under the terms of Section 1 93*ced89be4SMichael Großeabove, provided that you also meet all of these conditions: 94*ced89be4SMichael Große 95*ced89be4SMichael Große a) You must cause the modified files to carry prominent notices 96*ced89be4SMichael Große stating that you changed the files and the date of any change. 97*ced89be4SMichael Große 98*ced89be4SMichael Große b) You must cause any work that you distribute or publish, that in 99*ced89be4SMichael Große whole or in part contains or is derived from the Program or any 100*ced89be4SMichael Große part thereof, to be licensed as a whole at no charge to all third 101*ced89be4SMichael Große parties under the terms of this License. 102*ced89be4SMichael Große 103*ced89be4SMichael Große c) If the modified program normally reads commands interactively 104*ced89be4SMichael Große when run, you must cause it, when started running for such 105*ced89be4SMichael Große interactive use in the most ordinary way, to print or display an 106*ced89be4SMichael Große announcement including an appropriate copyright notice and a 107*ced89be4SMichael Große notice that there is no warranty (or else, saying that you provide 108*ced89be4SMichael Große a warranty) and that users may redistribute the program under 109*ced89be4SMichael Große these conditions, and telling the user how to view a copy of this 110*ced89be4SMichael Große License. (Exception: if the Program itself is interactive but 111*ced89be4SMichael Große does not normally print such an announcement, your work based on 112*ced89be4SMichael Große the Program is not required to print an announcement.) 113*ced89be4SMichael Große 114*ced89be4SMichael GroßeThese requirements apply to the modified work as a whole. If 115*ced89be4SMichael Großeidentifiable sections of that work are not derived from the Program, 116*ced89be4SMichael Großeand can be reasonably considered independent and separate works in 117*ced89be4SMichael Großethemselves, then this License, and its terms, do not apply to those 118*ced89be4SMichael Großesections when you distribute them as separate works. But when you 119*ced89be4SMichael Großedistribute the same sections as part of a whole which is a work based 120*ced89be4SMichael Großeon the Program, the distribution of the whole must be on the terms of 121*ced89be4SMichael Großethis License, whose permissions for other licensees extend to the 122*ced89be4SMichael Großeentire whole, and thus to each and every part regardless of who wrote it. 123*ced89be4SMichael Große 124*ced89be4SMichael GroßeThus, it is not the intent of this section to claim rights or contest 125*ced89be4SMichael Großeyour rights to work written entirely by you; rather, the intent is to 126*ced89be4SMichael Großeexercise the right to control the distribution of derivative or 127*ced89be4SMichael Großecollective works based on the Program. 128*ced89be4SMichael Große 129*ced89be4SMichael GroßeIn addition, mere aggregation of another work not based on the Program 130*ced89be4SMichael Großewith the Program (or with a work based on the Program) on a volume of 131*ced89be4SMichael Großea storage or distribution medium does not bring the other work under 132*ced89be4SMichael Großethe scope of this License. 133*ced89be4SMichael Große 134*ced89be4SMichael Große 3. You may copy and distribute the Program (or a work based on it, 135*ced89be4SMichael Großeunder Section 2) in object code or executable form under the terms of 136*ced89be4SMichael GroßeSections 1 and 2 above provided that you also do one of the following: 137*ced89be4SMichael Große 138*ced89be4SMichael Große a) Accompany it with the complete corresponding machine-readable 139*ced89be4SMichael Große source code, which must be distributed under the terms of Sections 140*ced89be4SMichael Große 1 and 2 above on a medium customarily used for software interchange; or, 141*ced89be4SMichael Große 142*ced89be4SMichael Große b) Accompany it with a written offer, valid for at least three 143*ced89be4SMichael Große years, to give any third party, for a charge no more than your 144*ced89be4SMichael Große cost of physically performing source distribution, a complete 145*ced89be4SMichael Große machine-readable copy of the corresponding source code, to be 146*ced89be4SMichael Große distributed under the terms of Sections 1 and 2 above on a medium 147*ced89be4SMichael Große customarily used for software interchange; or, 148*ced89be4SMichael Große 149*ced89be4SMichael Große c) Accompany it with the information you received as to the offer 150*ced89be4SMichael Große to distribute corresponding source code. (This alternative is 151*ced89be4SMichael Große allowed only for noncommercial distribution and only if you 152*ced89be4SMichael Große received the program in object code or executable form with such 153*ced89be4SMichael Große an offer, in accord with Subsection b above.) 154*ced89be4SMichael Große 155*ced89be4SMichael GroßeThe source code for a work means the preferred form of the work for 156*ced89be4SMichael Großemaking modifications to it. For an executable work, complete source 157*ced89be4SMichael Großecode means all the source code for all modules it contains, plus any 158*ced89be4SMichael Großeassociated interface definition files, plus the scripts used to 159*ced89be4SMichael Großecontrol compilation and installation of the executable. However, as a 160*ced89be4SMichael Großespecial exception, the source code distributed need not include 161*ced89be4SMichael Großeanything that is normally distributed (in either source or binary 162*ced89be4SMichael Großeform) with the major components (compiler, kernel, and so on) of the 163*ced89be4SMichael Großeoperating system on which the executable runs, unless that component 164*ced89be4SMichael Großeitself accompanies the executable. 165*ced89be4SMichael Große 166*ced89be4SMichael GroßeIf distribution of executable or object code is made by offering 167*ced89be4SMichael Großeaccess to copy from a designated place, then offering equivalent 168*ced89be4SMichael Großeaccess to copy the source code from the same place counts as 169*ced89be4SMichael Großedistribution of the source code, even though third parties are not 170*ced89be4SMichael Großecompelled to copy the source along with the object code. 171*ced89be4SMichael Große 172*ced89be4SMichael Große 4. You may not copy, modify, sublicense, or distribute the Program 173*ced89be4SMichael Großeexcept as expressly provided under this License. Any attempt 174*ced89be4SMichael Großeotherwise to copy, modify, sublicense or distribute the Program is 175*ced89be4SMichael Großevoid, and will automatically terminate your rights under this License. 176*ced89be4SMichael GroßeHowever, parties who have received copies, or rights, from you under 177*ced89be4SMichael Großethis License will not have their licenses terminated so long as such 178*ced89be4SMichael Großeparties remain in full compliance. 179*ced89be4SMichael Große 180*ced89be4SMichael Große 5. You are not required to accept this License, since you have not 181*ced89be4SMichael Großesigned it. However, nothing else grants you permission to modify or 182*ced89be4SMichael Großedistribute the Program or its derivative works. These actions are 183*ced89be4SMichael Großeprohibited by law if you do not accept this License. Therefore, by 184*ced89be4SMichael Großemodifying or distributing the Program (or any work based on the 185*ced89be4SMichael GroßeProgram), you indicate your acceptance of this License to do so, and 186*ced89be4SMichael Großeall its terms and conditions for copying, distributing or modifying 187*ced89be4SMichael Großethe Program or works based on it. 188*ced89be4SMichael Große 189*ced89be4SMichael Große 6. Each time you redistribute the Program (or any work based on the 190*ced89be4SMichael GroßeProgram), the recipient automatically receives a license from the 191*ced89be4SMichael Großeoriginal licensor to copy, distribute or modify the Program subject to 192*ced89be4SMichael Großethese terms and conditions. You may not impose any further 193*ced89be4SMichael Großerestrictions on the recipients' exercise of the rights granted herein. 194*ced89be4SMichael GroßeYou are not responsible for enforcing compliance by third parties to 195*ced89be4SMichael Großethis License. 196*ced89be4SMichael Große 197*ced89be4SMichael Große 7. If, as a consequence of a court judgment or allegation of patent 198*ced89be4SMichael Großeinfringement or for any other reason (not limited to patent issues), 199*ced89be4SMichael Großeconditions are imposed on you (whether by court order, agreement or 200*ced89be4SMichael Großeotherwise) that contradict the conditions of this License, they do not 201*ced89be4SMichael Großeexcuse you from the conditions of this License. If you cannot 202*ced89be4SMichael Großedistribute so as to satisfy simultaneously your obligations under this 203*ced89be4SMichael GroßeLicense and any other pertinent obligations, then as a consequence you 204*ced89be4SMichael Großemay not distribute the Program at all. For example, if a patent 205*ced89be4SMichael Großelicense would not permit royalty-free redistribution of the Program by 206*ced89be4SMichael Großeall those who receive copies directly or indirectly through you, then 207*ced89be4SMichael Großethe only way you could satisfy both it and this License would be to 208*ced89be4SMichael Großerefrain entirely from distribution of the Program. 209*ced89be4SMichael Große 210*ced89be4SMichael GroßeIf any portion of this section is held invalid or unenforceable under 211*ced89be4SMichael Großeany particular circumstance, the balance of the section is intended to 212*ced89be4SMichael Großeapply and the section as a whole is intended to apply in other 213*ced89be4SMichael Großecircumstances. 214*ced89be4SMichael Große 215*ced89be4SMichael GroßeIt is not the purpose of this section to induce you to infringe any 216*ced89be4SMichael Großepatents or other property right claims or to contest validity of any 217*ced89be4SMichael Großesuch claims; this section has the sole purpose of protecting the 218*ced89be4SMichael Großeintegrity of the free software distribution system, which is 219*ced89be4SMichael Großeimplemented by public license practices. Many people have made 220*ced89be4SMichael Großegenerous contributions to the wide range of software distributed 221*ced89be4SMichael Großethrough that system in reliance on consistent application of that 222*ced89be4SMichael Großesystem; it is up to the author/donor to decide if he or she is willing 223*ced89be4SMichael Großeto distribute software through any other system and a licensee cannot 224*ced89be4SMichael Großeimpose that choice. 225*ced89be4SMichael Große 226*ced89be4SMichael GroßeThis section is intended to make thoroughly clear what is believed to 227*ced89be4SMichael Großebe a consequence of the rest of this License. 228*ced89be4SMichael Große 229*ced89be4SMichael Große 8. If the distribution and/or use of the Program is restricted in 230*ced89be4SMichael Großecertain countries either by patents or by copyrighted interfaces, the 231*ced89be4SMichael Großeoriginal copyright holder who places the Program under this License 232*ced89be4SMichael Großemay add an explicit geographical distribution limitation excluding 233*ced89be4SMichael Großethose countries, so that distribution is permitted only in or among 234*ced89be4SMichael Großecountries not thus excluded. In such case, this License incorporates 235*ced89be4SMichael Großethe limitation as if written in the body of this License. 236*ced89be4SMichael Große 237*ced89be4SMichael Große 9. The Free Software Foundation may publish revised and/or new versions 238*ced89be4SMichael Großeof the General Public License from time to time. Such new versions will 239*ced89be4SMichael Großebe similar in spirit to the present version, but may differ in detail to 240*ced89be4SMichael Großeaddress new problems or concerns. 241*ced89be4SMichael Große 242*ced89be4SMichael GroßeEach version is given a distinguishing version number. If the Program 243*ced89be4SMichael Großespecifies a version number of this License which applies to it and "any 244*ced89be4SMichael Großelater version", you have the option of following the terms and conditions 245*ced89be4SMichael Großeeither of that version or of any later version published by the Free 246*ced89be4SMichael GroßeSoftware Foundation. If the Program does not specify a version number of 247*ced89be4SMichael Großethis License, you may choose any version ever published by the Free Software 248*ced89be4SMichael GroßeFoundation. 249*ced89be4SMichael Große 250*ced89be4SMichael Große 10. If you wish to incorporate parts of the Program into other free 251*ced89be4SMichael Großeprograms whose distribution conditions are different, write to the author 252*ced89be4SMichael Großeto ask for permission. For software which is copyrighted by the Free 253*ced89be4SMichael GroßeSoftware Foundation, write to the Free Software Foundation; we sometimes 254*ced89be4SMichael Großemake exceptions for this. Our decision will be guided by the two goals 255*ced89be4SMichael Großeof preserving the free status of all derivatives of our free software and 256*ced89be4SMichael Großeof promoting the sharing and reuse of software generally. 257*ced89be4SMichael Große 258*ced89be4SMichael Große NO WARRANTY 259*ced89be4SMichael Große 260*ced89be4SMichael Große 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261*ced89be4SMichael GroßeFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262*ced89be4SMichael GroßeOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263*ced89be4SMichael GroßePROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264*ced89be4SMichael GroßeOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265*ced89be4SMichael GroßeMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 266*ced89be4SMichael GroßeTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 267*ced89be4SMichael GroßePROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 268*ced89be4SMichael GroßeREPAIR OR CORRECTION. 269*ced89be4SMichael Große 270*ced89be4SMichael Große 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 271*ced89be4SMichael GroßeWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 272*ced89be4SMichael GroßeREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 273*ced89be4SMichael GroßeINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 274*ced89be4SMichael GroßeOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 275*ced89be4SMichael GroßeTO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 276*ced89be4SMichael GroßeYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 277*ced89be4SMichael GroßePROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 278*ced89be4SMichael GroßePOSSIBILITY OF SUCH DAMAGES. 279*ced89be4SMichael Große 280*ced89be4SMichael Große END OF TERMS AND CONDITIONS 281*ced89be4SMichael Große 282*ced89be4SMichael Große How to Apply These Terms to Your New Programs 283*ced89be4SMichael Große 284*ced89be4SMichael Große If you develop a new program, and you want it to be of the greatest 285*ced89be4SMichael Großepossible use to the public, the best way to achieve this is to make it 286*ced89be4SMichael Großefree software which everyone can redistribute and change under these terms. 287*ced89be4SMichael Große 288*ced89be4SMichael Große To do so, attach the following notices to the program. It is safest 289*ced89be4SMichael Großeto attach them to the start of each source file to most effectively 290*ced89be4SMichael Großeconvey the exclusion of warranty; and each file should have at least 291*ced89be4SMichael Großethe "copyright" line and a pointer to where the full notice is found. 292*ced89be4SMichael Große 293*ced89be4SMichael Große <one line to give the program's name and a brief idea of what it does.> 294*ced89be4SMichael Große Copyright (C) <year> <name of author> 295*ced89be4SMichael Große 296*ced89be4SMichael Große This program is free software; you can redistribute it and/or modify 297*ced89be4SMichael Große it under the terms of the GNU General Public License as published by 298*ced89be4SMichael Große the Free Software Foundation; either version 2 of the License, or 299*ced89be4SMichael Große (at your option) any later version. 300*ced89be4SMichael Große 301*ced89be4SMichael Große This program is distributed in the hope that it will be useful, 302*ced89be4SMichael Große but WITHOUT ANY WARRANTY; without even the implied warranty of 303*ced89be4SMichael Große MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Of course, the commands you use may 322*ced89be4SMichael Großebe called something other than `show w' and `show c'; they could even be 323*ced89be4SMichael Großemouse-clicks or menu items--whatever suits your program. 324*ced89be4SMichael Große 325*ced89be4SMichael GroßeYou should also get your employer (if you work as a programmer) or your 326*ced89be4SMichael Großeschool, if any, to sign a "copyright disclaimer" for the program, if 327*ced89be4SMichael Großenecessary. Here is a sample; alter the names: 328*ced89be4SMichael Große 329*ced89be4SMichael Große Yoyodyne, Inc., hereby disclaims all copyright interest in the program 330*ced89be4SMichael Große `Gnomovision' (which makes passes at compilers) written by James Hacker. 331*ced89be4SMichael Große 332*ced89be4SMichael Große <signature of Ty Coon>, 1 April 1989 333*ced89be4SMichael Große Ty Coon, President of Vice 334*ced89be4SMichael Große 335*ced89be4SMichael GroßeThis General Public License does not permit incorporating your program into 336*ced89be4SMichael Großeproprietary programs.
