1*a28cd43dSSascha Wildner GNU GENERAL PUBLIC LICENSE 2*a28cd43dSSascha Wildner Version 2, June 1991 3*a28cd43dSSascha Wildner 4*a28cd43dSSascha Wildner Copyright (C) 1989, 1991 Free Software Foundation, Inc., 5*a28cd43dSSascha Wildner 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA 6*a28cd43dSSascha Wildner Everyone is permitted to copy and distribute verbatim copies 7*a28cd43dSSascha Wildner of this license document, but changing it is not allowed. 8*a28cd43dSSascha Wildner 9*a28cd43dSSascha Wildner Preamble 10*a28cd43dSSascha Wildner 11*a28cd43dSSascha Wildner The licenses for most software are designed to take away your 12*a28cd43dSSascha Wildnerfreedom to share and change it. By contrast, the GNU General Public 13*a28cd43dSSascha WildnerLicense is intended to guarantee your freedom to share and change free 14*a28cd43dSSascha Wildnersoftware--to make sure the software is free for all its users. This 15*a28cd43dSSascha WildnerGeneral Public License applies to most of the Free Software 16*a28cd43dSSascha WildnerFoundation's software and to any other program whose authors commit to 17*a28cd43dSSascha Wildnerusing it. (Some other Free Software Foundation software is covered by 18*a28cd43dSSascha Wildnerthe GNU Lesser General Public License instead.) You can apply it to 19*a28cd43dSSascha Wildneryour programs, too. 20*a28cd43dSSascha Wildner 21*a28cd43dSSascha Wildner When we speak of free software, we are referring to freedom, not 22*a28cd43dSSascha Wildnerprice. Our General Public Licenses are designed to make sure that you 23*a28cd43dSSascha Wildnerhave the freedom to distribute copies of free software (and charge for 24*a28cd43dSSascha Wildnerthis service if you wish), that you receive source code or can get it 25*a28cd43dSSascha Wildnerif you want it, that you can change the software or use pieces of it 26*a28cd43dSSascha Wildnerin new free programs; and that you know you can do these things. 27*a28cd43dSSascha Wildner 28*a28cd43dSSascha Wildner To protect your rights, we need to make restrictions that forbid 29*a28cd43dSSascha Wildneranyone to deny you these rights or to ask you to surrender the rights. 30*a28cd43dSSascha WildnerThese restrictions translate to certain responsibilities for you if you 31*a28cd43dSSascha Wildnerdistribute copies of the software, or if you modify it. 32*a28cd43dSSascha Wildner 33*a28cd43dSSascha Wildner For example, if you distribute copies of such a program, whether 34*a28cd43dSSascha Wildnergratis or for a fee, you must give the recipients all the rights that 35*a28cd43dSSascha Wildneryou have. You must make sure that they, too, receive or can get the 36*a28cd43dSSascha Wildnersource code. And you must show them these terms so they know their 37*a28cd43dSSascha Wildnerrights. 38*a28cd43dSSascha Wildner 39*a28cd43dSSascha Wildner We protect your rights with two steps: (1) copyright the software, and 40*a28cd43dSSascha Wildner(2) offer you this license which gives you legal permission to copy, 41*a28cd43dSSascha Wildnerdistribute and/or modify the software. 42*a28cd43dSSascha Wildner 43*a28cd43dSSascha Wildner Also, for each author's protection and ours, we want to make certain 44*a28cd43dSSascha Wildnerthat everyone understands that there is no warranty for this free 45*a28cd43dSSascha Wildnersoftware. If the software is modified by someone else and passed on, we 46*a28cd43dSSascha Wildnerwant its recipients to know that what they have is not the original, so 47*a28cd43dSSascha Wildnerthat any problems introduced by others will not reflect on the original 48*a28cd43dSSascha Wildnerauthors' reputations. 49*a28cd43dSSascha Wildner 50*a28cd43dSSascha Wildner Finally, any free program is threatened constantly by software 51*a28cd43dSSascha Wildnerpatents. We wish to avoid the danger that redistributors of a free 52*a28cd43dSSascha Wildnerprogram will individually obtain patent licenses, in effect making the 53*a28cd43dSSascha Wildnerprogram proprietary. To prevent this, we have made it clear that any 54*a28cd43dSSascha Wildnerpatent must be licensed for everyone's free use or not licensed at all. 55*a28cd43dSSascha Wildner 56*a28cd43dSSascha Wildner The precise terms and conditions for copying, distribution and 57*a28cd43dSSascha Wildnermodification follow. 58*a28cd43dSSascha Wildner 59*a28cd43dSSascha Wildner GNU GENERAL PUBLIC LICENSE 60*a28cd43dSSascha Wildner TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61*a28cd43dSSascha Wildner 62*a28cd43dSSascha Wildner 0. This License applies to any program or other work which contains 63*a28cd43dSSascha Wildnera notice placed by the copyright holder saying it may be distributed 64*a28cd43dSSascha Wildnerunder the terms of this General Public License. The "Program", below, 65*a28cd43dSSascha Wildnerrefers to any such program or work, and a "work based on the Program" 66*a28cd43dSSascha Wildnermeans either the Program or any derivative work under copyright law: 67*a28cd43dSSascha Wildnerthat is to say, a work containing the Program or a portion of it, 68*a28cd43dSSascha Wildnereither verbatim or with modifications and/or translated into another 69*a28cd43dSSascha Wildnerlanguage. (Hereinafter, translation is included without limitation in 70*a28cd43dSSascha Wildnerthe term "modification".) Each licensee is addressed as "you". 71*a28cd43dSSascha Wildner 72*a28cd43dSSascha WildnerActivities other than copying, distribution and modification are not 73*a28cd43dSSascha Wildnercovered by this License; they are outside its scope. The act of 74*a28cd43dSSascha Wildnerrunning the Program is not restricted, and the output from the Program 75*a28cd43dSSascha Wildneris covered only if its contents constitute a work based on the 76*a28cd43dSSascha WildnerProgram (independent of having been made by running the Program). 77*a28cd43dSSascha WildnerWhether that is true depends on what the Program does. 78*a28cd43dSSascha Wildner 79*a28cd43dSSascha Wildner 1. You may copy and distribute verbatim copies of the Program's 80*a28cd43dSSascha Wildnersource code as you receive it, in any medium, provided that you 81*a28cd43dSSascha Wildnerconspicuously and appropriately publish on each copy an appropriate 82*a28cd43dSSascha Wildnercopyright notice and disclaimer of warranty; keep intact all the 83*a28cd43dSSascha Wildnernotices that refer to this License and to the absence of any warranty; 84*a28cd43dSSascha Wildnerand give any other recipients of the Program a copy of this License 85*a28cd43dSSascha Wildneralong with the Program. 86*a28cd43dSSascha Wildner 87*a28cd43dSSascha WildnerYou may charge a fee for the physical act of transferring a copy, and 88*a28cd43dSSascha Wildneryou may at your option offer warranty protection in exchange for a fee. 89*a28cd43dSSascha Wildner 90*a28cd43dSSascha Wildner 2. You may modify your copy or copies of the Program or any portion 91*a28cd43dSSascha Wildnerof it, thus forming a work based on the Program, and copy and 92*a28cd43dSSascha Wildnerdistribute such modifications or work under the terms of Section 1 93*a28cd43dSSascha Wildnerabove, provided that you also meet all of these conditions: 94*a28cd43dSSascha Wildner 95*a28cd43dSSascha Wildner a) You must cause the modified files to carry prominent notices 96*a28cd43dSSascha Wildner stating that you changed the files and the date of any change. 97*a28cd43dSSascha Wildner 98*a28cd43dSSascha Wildner b) You must cause any work that you distribute or publish, that in 99*a28cd43dSSascha Wildner whole or in part contains or is derived from the Program or any 100*a28cd43dSSascha Wildner part thereof, to be licensed as a whole at no charge to all third 101*a28cd43dSSascha Wildner parties under the terms of this License. 102*a28cd43dSSascha Wildner 103*a28cd43dSSascha Wildner c) If the modified program normally reads commands interactively 104*a28cd43dSSascha Wildner when run, you must cause it, when started running for such 105*a28cd43dSSascha Wildner interactive use in the most ordinary way, to print or display an 106*a28cd43dSSascha Wildner announcement including an appropriate copyright notice and a 107*a28cd43dSSascha Wildner notice that there is no warranty (or else, saying that you provide 108*a28cd43dSSascha Wildner a warranty) and that users may redistribute the program under 109*a28cd43dSSascha Wildner these conditions, and telling the user how to view a copy of this 110*a28cd43dSSascha Wildner License. (Exception: if the Program itself is interactive but 111*a28cd43dSSascha Wildner does not normally print such an announcement, your work based on 112*a28cd43dSSascha Wildner the Program is not required to print an announcement.) 113*a28cd43dSSascha Wildner 114*a28cd43dSSascha WildnerThese requirements apply to the modified work as a whole. If 115*a28cd43dSSascha Wildneridentifiable sections of that work are not derived from the Program, 116*a28cd43dSSascha Wildnerand can be reasonably considered independent and separate works in 117*a28cd43dSSascha Wildnerthemselves, then this License, and its terms, do not apply to those 118*a28cd43dSSascha Wildnersections when you distribute them as separate works. But when you 119*a28cd43dSSascha Wildnerdistribute the same sections as part of a whole which is a work based 120*a28cd43dSSascha Wildneron the Program, the distribution of the whole must be on the terms of 121*a28cd43dSSascha Wildnerthis License, whose permissions for other licensees extend to the 122*a28cd43dSSascha Wildnerentire whole, and thus to each and every part regardless of who wrote it. 123*a28cd43dSSascha Wildner 124*a28cd43dSSascha WildnerThus, it is not the intent of this section to claim rights or contest 125*a28cd43dSSascha Wildneryour rights to work written entirely by you; rather, the intent is to 126*a28cd43dSSascha Wildnerexercise the right to control the distribution of derivative or 127*a28cd43dSSascha Wildnercollective works based on the Program. 128*a28cd43dSSascha Wildner 129*a28cd43dSSascha WildnerIn addition, mere aggregation of another work not based on the Program 130*a28cd43dSSascha Wildnerwith the Program (or with a work based on the Program) on a volume of 131*a28cd43dSSascha Wildnera storage or distribution medium does not bring the other work under 132*a28cd43dSSascha Wildnerthe scope of this License. 133*a28cd43dSSascha Wildner 134*a28cd43dSSascha Wildner 3. You may copy and distribute the Program (or a work based on it, 135*a28cd43dSSascha Wildnerunder Section 2) in object code or executable form under the terms of 136*a28cd43dSSascha WildnerSections 1 and 2 above provided that you also do one of the following: 137*a28cd43dSSascha Wildner 138*a28cd43dSSascha Wildner a) Accompany it with the complete corresponding machine-readable 139*a28cd43dSSascha Wildner source code, which must be distributed under the terms of Sections 140*a28cd43dSSascha Wildner 1 and 2 above on a medium customarily used for software interchange; or, 141*a28cd43dSSascha Wildner 142*a28cd43dSSascha Wildner b) Accompany it with a written offer, valid for at least three 143*a28cd43dSSascha Wildner years, to give any third party, for a charge no more than your 144*a28cd43dSSascha Wildner cost of physically performing source distribution, a complete 145*a28cd43dSSascha Wildner machine-readable copy of the corresponding source code, to be 146*a28cd43dSSascha Wildner distributed under the terms of Sections 1 and 2 above on a medium 147*a28cd43dSSascha Wildner customarily used for software interchange; or, 148*a28cd43dSSascha Wildner 149*a28cd43dSSascha Wildner c) Accompany it with the information you received as to the offer 150*a28cd43dSSascha Wildner to distribute corresponding source code. (This alternative is 151*a28cd43dSSascha Wildner allowed only for noncommercial distribution and only if you 152*a28cd43dSSascha Wildner received the program in object code or executable form with such 153*a28cd43dSSascha Wildner an offer, in accord with Subsection b above.) 154*a28cd43dSSascha Wildner 155*a28cd43dSSascha WildnerThe source code for a work means the preferred form of the work for 156*a28cd43dSSascha Wildnermaking modifications to it. For an executable work, complete source 157*a28cd43dSSascha Wildnercode means all the source code for all modules it contains, plus any 158*a28cd43dSSascha Wildnerassociated interface definition files, plus the scripts used to 159*a28cd43dSSascha Wildnercontrol compilation and installation of the executable. However, as a 160*a28cd43dSSascha Wildnerspecial exception, the source code distributed need not include 161*a28cd43dSSascha Wildneranything that is normally distributed (in either source or binary 162*a28cd43dSSascha Wildnerform) with the major components (compiler, kernel, and so on) of the 163*a28cd43dSSascha Wildneroperating system on which the executable runs, unless that component 164*a28cd43dSSascha Wildneritself accompanies the executable. 165*a28cd43dSSascha Wildner 166*a28cd43dSSascha WildnerIf distribution of executable or object code is made by offering 167*a28cd43dSSascha Wildneraccess to copy from a designated place, then offering equivalent 168*a28cd43dSSascha Wildneraccess to copy the source code from the same place counts as 169*a28cd43dSSascha Wildnerdistribution of the source code, even though third parties are not 170*a28cd43dSSascha Wildnercompelled to copy the source along with the object code. 171*a28cd43dSSascha Wildner 172*a28cd43dSSascha Wildner 4. You may not copy, modify, sublicense, or distribute the Program 173*a28cd43dSSascha Wildnerexcept as expressly provided under this License. Any attempt 174*a28cd43dSSascha Wildnerotherwise to copy, modify, sublicense or distribute the Program is 175*a28cd43dSSascha Wildnervoid, and will automatically terminate your rights under this License. 176*a28cd43dSSascha WildnerHowever, parties who have received copies, or rights, from you under 177*a28cd43dSSascha Wildnerthis License will not have their licenses terminated so long as such 178*a28cd43dSSascha Wildnerparties remain in full compliance. 179*a28cd43dSSascha Wildner 180*a28cd43dSSascha Wildner 5. You are not required to accept this License, since you have not 181*a28cd43dSSascha Wildnersigned it. However, nothing else grants you permission to modify or 182*a28cd43dSSascha Wildnerdistribute the Program or its derivative works. These actions are 183*a28cd43dSSascha Wildnerprohibited by law if you do not accept this License. Therefore, by 184*a28cd43dSSascha Wildnermodifying or distributing the Program (or any work based on the 185*a28cd43dSSascha WildnerProgram), you indicate your acceptance of this License to do so, and 186*a28cd43dSSascha Wildnerall its terms and conditions for copying, distributing or modifying 187*a28cd43dSSascha Wildnerthe Program or works based on it. 188*a28cd43dSSascha Wildner 189*a28cd43dSSascha Wildner 6. Each time you redistribute the Program (or any work based on the 190*a28cd43dSSascha WildnerProgram), the recipient automatically receives a license from the 191*a28cd43dSSascha Wildneroriginal licensor to copy, distribute or modify the Program subject to 192*a28cd43dSSascha Wildnerthese terms and conditions. You may not impose any further 193*a28cd43dSSascha Wildnerrestrictions on the recipients' exercise of the rights granted herein. 194*a28cd43dSSascha WildnerYou are not responsible for enforcing compliance by third parties to 195*a28cd43dSSascha Wildnerthis License. 196*a28cd43dSSascha Wildner 197*a28cd43dSSascha Wildner 7. If, as a consequence of a court judgment or allegation of patent 198*a28cd43dSSascha Wildnerinfringement or for any other reason (not limited to patent issues), 199*a28cd43dSSascha Wildnerconditions are imposed on you (whether by court order, agreement or 200*a28cd43dSSascha Wildnerotherwise) that contradict the conditions of this License, they do not 201*a28cd43dSSascha Wildnerexcuse you from the conditions of this License. If you cannot 202*a28cd43dSSascha Wildnerdistribute so as to satisfy simultaneously your obligations under this 203*a28cd43dSSascha WildnerLicense and any other pertinent obligations, then as a consequence you 204*a28cd43dSSascha Wildnermay not distribute the Program at all. For example, if a patent 205*a28cd43dSSascha Wildnerlicense would not permit royalty-free redistribution of the Program by 206*a28cd43dSSascha Wildnerall those who receive copies directly or indirectly through you, then 207*a28cd43dSSascha Wildnerthe only way you could satisfy both it and this License would be to 208*a28cd43dSSascha Wildnerrefrain entirely from distribution of the Program. 209*a28cd43dSSascha Wildner 210*a28cd43dSSascha WildnerIf any portion of this section is held invalid or unenforceable under 211*a28cd43dSSascha Wildnerany particular circumstance, the balance of the section is intended to 212*a28cd43dSSascha Wildnerapply and the section as a whole is intended to apply in other 213*a28cd43dSSascha Wildnercircumstances. 214*a28cd43dSSascha Wildner 215*a28cd43dSSascha WildnerIt is not the purpose of this section to induce you to infringe any 216*a28cd43dSSascha Wildnerpatents or other property right claims or to contest validity of any 217*a28cd43dSSascha Wildnersuch claims; this section has the sole purpose of protecting the 218*a28cd43dSSascha Wildnerintegrity of the free software distribution system, which is 219*a28cd43dSSascha Wildnerimplemented by public license practices. Many people have made 220*a28cd43dSSascha Wildnergenerous contributions to the wide range of software distributed 221*a28cd43dSSascha Wildnerthrough that system in reliance on consistent application of that 222*a28cd43dSSascha Wildnersystem; it is up to the author/donor to decide if he or she is willing 223*a28cd43dSSascha Wildnerto distribute software through any other system and a licensee cannot 224*a28cd43dSSascha Wildnerimpose that choice. 225*a28cd43dSSascha Wildner 226*a28cd43dSSascha WildnerThis section is intended to make thoroughly clear what is believed to 227*a28cd43dSSascha Wildnerbe a consequence of the rest of this License. 228*a28cd43dSSascha Wildner 229*a28cd43dSSascha Wildner 8. If the distribution and/or use of the Program is restricted in 230*a28cd43dSSascha Wildnercertain countries either by patents or by copyrighted interfaces, the 231*a28cd43dSSascha Wildneroriginal copyright holder who places the Program under this License 232*a28cd43dSSascha Wildnermay add an explicit geographical distribution limitation excluding 233*a28cd43dSSascha Wildnerthose countries, so that distribution is permitted only in or among 234*a28cd43dSSascha Wildnercountries not thus excluded. In such case, this License incorporates 235*a28cd43dSSascha Wildnerthe limitation as if written in the body of this License. 236*a28cd43dSSascha Wildner 237*a28cd43dSSascha Wildner 9. The Free Software Foundation may publish revised and/or new versions 238*a28cd43dSSascha Wildnerof the General Public License from time to time. Such new versions will 239*a28cd43dSSascha Wildnerbe similar in spirit to the present version, but may differ in detail to 240*a28cd43dSSascha Wildneraddress new problems or concerns. 241*a28cd43dSSascha Wildner 242*a28cd43dSSascha WildnerEach version is given a distinguishing version number. If the Program 243*a28cd43dSSascha Wildnerspecifies a version number of this License which applies to it and "any 244*a28cd43dSSascha Wildnerlater version", you have the option of following the terms and conditions 245*a28cd43dSSascha Wildnereither of that version or of any later version published by the Free 246*a28cd43dSSascha WildnerSoftware Foundation. If the Program does not specify a version number of 247*a28cd43dSSascha Wildnerthis License, you may choose any version ever published by the Free Software 248*a28cd43dSSascha WildnerFoundation. 249*a28cd43dSSascha Wildner 250*a28cd43dSSascha Wildner 10. If you wish to incorporate parts of the Program into other free 251*a28cd43dSSascha Wildnerprograms whose distribution conditions are different, write to the author 252*a28cd43dSSascha Wildnerto ask for permission. For software which is copyrighted by the Free 253*a28cd43dSSascha WildnerSoftware Foundation, write to the Free Software Foundation; we sometimes 254*a28cd43dSSascha Wildnermake exceptions for this. Our decision will be guided by the two goals 255*a28cd43dSSascha Wildnerof preserving the free status of all derivatives of our free software and 256*a28cd43dSSascha Wildnerof promoting the sharing and reuse of software generally. 257*a28cd43dSSascha Wildner 258*a28cd43dSSascha Wildner NO WARRANTY 259*a28cd43dSSascha Wildner 260*a28cd43dSSascha Wildner 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261*a28cd43dSSascha WildnerFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262*a28cd43dSSascha WildnerOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263*a28cd43dSSascha WildnerPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264*a28cd43dSSascha WildnerOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265*a28cd43dSSascha WildnerMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 266*a28cd43dSSascha WildnerTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
