1*a3092f6cSAndreas Gohr GNU GENERAL PUBLIC LICENSE 2*a3092f6cSAndreas Gohr Version 2, June 1991 3*a3092f6cSAndreas Gohr 4*a3092f6cSAndreas Gohr Copyright (C) 1989, 1991 Free Software Foundation, Inc., 5*a3092f6cSAndreas Gohr 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA 6*a3092f6cSAndreas Gohr Everyone is permitted to copy and distribute verbatim copies 7*a3092f6cSAndreas Gohr of this license document, but changing it is not allowed. 8*a3092f6cSAndreas Gohr 9*a3092f6cSAndreas Gohr Preamble 10*a3092f6cSAndreas Gohr 11*a3092f6cSAndreas Gohr The licenses for most software are designed to take away your 12*a3092f6cSAndreas Gohrfreedom to share and change it. By contrast, the GNU General Public 13*a3092f6cSAndreas GohrLicense is intended to guarantee your freedom to share and change free 14*a3092f6cSAndreas Gohrsoftware--to make sure the software is free for all its users. This 15*a3092f6cSAndreas GohrGeneral Public License applies to most of the Free Software 16*a3092f6cSAndreas GohrFoundation's software and to any other program whose authors commit to 17*a3092f6cSAndreas Gohrusing it. (Some other Free Software Foundation software is covered by 18*a3092f6cSAndreas Gohrthe GNU Lesser General Public License instead.) You can apply it to 19*a3092f6cSAndreas Gohryour programs, too. 20*a3092f6cSAndreas Gohr 21*a3092f6cSAndreas Gohr When we speak of free software, we are referring to freedom, not 22*a3092f6cSAndreas Gohrprice. Our General Public Licenses are designed to make sure that you 23*a3092f6cSAndreas Gohrhave the freedom to distribute copies of free software (and charge for 24*a3092f6cSAndreas Gohrthis service if you wish), that you receive source code or can get it 25*a3092f6cSAndreas Gohrif you want it, that you can change the software or use pieces of it 26*a3092f6cSAndreas Gohrin new free programs; and that you know you can do these things. 27*a3092f6cSAndreas Gohr 28*a3092f6cSAndreas Gohr To protect your rights, we need to make restrictions that forbid 29*a3092f6cSAndreas Gohranyone to deny you these rights or to ask you to surrender the rights. 30*a3092f6cSAndreas GohrThese restrictions translate to certain responsibilities for you if you 31*a3092f6cSAndreas Gohrdistribute copies of the software, or if you modify it. 32*a3092f6cSAndreas Gohr 33*a3092f6cSAndreas Gohr For example, if you distribute copies of such a program, whether 34*a3092f6cSAndreas Gohrgratis or for a fee, you must give the recipients all the rights that 35*a3092f6cSAndreas Gohryou have. You must make sure that they, too, receive or can get the 36*a3092f6cSAndreas Gohrsource code. And you must show them these terms so they know their 37*a3092f6cSAndreas Gohrrights. 38*a3092f6cSAndreas Gohr 39*a3092f6cSAndreas Gohr We protect your rights with two steps: (1) copyright the software, and 40*a3092f6cSAndreas Gohr(2) offer you this license which gives you legal permission to copy, 41*a3092f6cSAndreas Gohrdistribute and/or modify the software. 42*a3092f6cSAndreas Gohr 43*a3092f6cSAndreas Gohr Also, for each author's protection and ours, we want to make certain 44*a3092f6cSAndreas Gohrthat everyone understands that there is no warranty for this free 45*a3092f6cSAndreas Gohrsoftware. If the software is modified by someone else and passed on, we 46*a3092f6cSAndreas Gohrwant its recipients to know that what they have is not the original, so 47*a3092f6cSAndreas Gohrthat any problems introduced by others will not reflect on the original 48*a3092f6cSAndreas Gohrauthors' reputations. 49*a3092f6cSAndreas Gohr 50*a3092f6cSAndreas Gohr Finally, any free program is threatened constantly by software 51*a3092f6cSAndreas Gohrpatents. We wish to avoid the danger that redistributors of a free 52*a3092f6cSAndreas Gohrprogram will individually obtain patent licenses, in effect making the 53*a3092f6cSAndreas Gohrprogram proprietary. To prevent this, we have made it clear that any 54*a3092f6cSAndreas Gohrpatent must be licensed for everyone's free use or not licensed at all. 55*a3092f6cSAndreas Gohr 56*a3092f6cSAndreas Gohr The precise terms and conditions for copying, distribution and 57*a3092f6cSAndreas Gohrmodification follow. 58*a3092f6cSAndreas Gohr 59*a3092f6cSAndreas Gohr GNU GENERAL PUBLIC LICENSE 60*a3092f6cSAndreas Gohr TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61*a3092f6cSAndreas Gohr 62*a3092f6cSAndreas Gohr 0. This License applies to any program or other work which contains 63*a3092f6cSAndreas Gohra notice placed by the copyright holder saying it may be distributed 64*a3092f6cSAndreas Gohrunder the terms of this General Public License. The "Program", below, 65*a3092f6cSAndreas Gohrrefers to any such program or work, and a "work based on the Program" 66*a3092f6cSAndreas Gohrmeans either the Program or any derivative work under copyright law: 67*a3092f6cSAndreas Gohrthat is to say, a work containing the Program or a portion of it, 68*a3092f6cSAndreas Gohreither verbatim or with modifications and/or translated into another 69*a3092f6cSAndreas Gohrlanguage. (Hereinafter, translation is included without limitation in 70*a3092f6cSAndreas Gohrthe term "modification".) Each licensee is addressed as "you". 71*a3092f6cSAndreas Gohr 72*a3092f6cSAndreas GohrActivities other than copying, distribution and modification are not 73*a3092f6cSAndreas Gohrcovered by this License; they are outside its scope. The act of 74*a3092f6cSAndreas Gohrrunning the Program is not restricted, and the output from the Program 75*a3092f6cSAndreas Gohris covered only if its contents constitute a work based on the 76*a3092f6cSAndreas GohrProgram (independent of having been made by running the Program). 77*a3092f6cSAndreas GohrWhether that is true depends on what the Program does. 78*a3092f6cSAndreas Gohr 79*a3092f6cSAndreas Gohr 1. You may copy and distribute verbatim copies of the Program's 80*a3092f6cSAndreas Gohrsource code as you receive it, in any medium, provided that you 81*a3092f6cSAndreas Gohrconspicuously and appropriately publish on each copy an appropriate 82*a3092f6cSAndreas Gohrcopyright notice and disclaimer of warranty; keep intact all the 83*a3092f6cSAndreas Gohrnotices that refer to this License and to the absence of any warranty; 84*a3092f6cSAndreas Gohrand give any other recipients of the Program a copy of this License 85*a3092f6cSAndreas Gohralong with the Program. 86*a3092f6cSAndreas Gohr 87*a3092f6cSAndreas GohrYou may charge a fee for the physical act of transferring a copy, and 88*a3092f6cSAndreas Gohryou may at your option offer warranty protection in exchange for a fee. 89*a3092f6cSAndreas Gohr 90*a3092f6cSAndreas Gohr 2. You may modify your copy or copies of the Program or any portion 91*a3092f6cSAndreas Gohrof it, thus forming a work based on the Program, and copy and 92*a3092f6cSAndreas Gohrdistribute such modifications or work under the terms of Section 1 93*a3092f6cSAndreas Gohrabove, provided that you also meet all of these conditions: 94*a3092f6cSAndreas Gohr 95*a3092f6cSAndreas Gohr a) You must cause the modified files to carry prominent notices 96*a3092f6cSAndreas Gohr stating that you changed the files and the date of any change. 97*a3092f6cSAndreas Gohr 98*a3092f6cSAndreas Gohr b) You must cause any work that you distribute or publish, that in 99*a3092f6cSAndreas Gohr whole or in part contains or is derived from the Program or any 100*a3092f6cSAndreas Gohr part thereof, to be licensed as a whole at no charge to all third 101*a3092f6cSAndreas Gohr parties under the terms of this License. 102*a3092f6cSAndreas Gohr 103*a3092f6cSAndreas Gohr c) If the modified program normally reads commands interactively 104*a3092f6cSAndreas Gohr when run, you must cause it, when started running for such 105*a3092f6cSAndreas Gohr interactive use in the most ordinary way, to print or display an 106*a3092f6cSAndreas Gohr announcement including an appropriate copyright notice and a 107*a3092f6cSAndreas Gohr notice that there is no warranty (or else, saying that you provide 108*a3092f6cSAndreas Gohr a warranty) and that users may redistribute the program under 109*a3092f6cSAndreas Gohr these conditions, and telling the user how to view a copy of this 110*a3092f6cSAndreas Gohr License. (Exception: if the Program itself is interactive but 111*a3092f6cSAndreas Gohr does not normally print such an announcement, your work based on 112*a3092f6cSAndreas Gohr the Program is not required to print an announcement.) 113*a3092f6cSAndreas Gohr 114*a3092f6cSAndreas GohrThese requirements apply to the modified work as a whole. If 115*a3092f6cSAndreas Gohridentifiable sections of that work are not derived from the Program, 116*a3092f6cSAndreas Gohrand can be reasonably considered independent and separate works in 117*a3092f6cSAndreas Gohrthemselves, then this License, and its terms, do not apply to those 118*a3092f6cSAndreas Gohrsections when you distribute them as separate works. But when you 119*a3092f6cSAndreas Gohrdistribute the same sections as part of a whole which is a work based 120*a3092f6cSAndreas Gohron the Program, the distribution of the whole must be on the terms of 121*a3092f6cSAndreas Gohrthis License, whose permissions for other licensees extend to the 122*a3092f6cSAndreas Gohrentire whole, and thus to each and every part regardless of who wrote it. 123*a3092f6cSAndreas Gohr 124*a3092f6cSAndreas GohrThus, it is not the intent of this section to claim rights or contest 125*a3092f6cSAndreas Gohryour rights to work written entirely by you; rather, the intent is to 126*a3092f6cSAndreas Gohrexercise the right to control the distribution of derivative or 127*a3092f6cSAndreas Gohrcollective works based on the Program. 128*a3092f6cSAndreas Gohr 129*a3092f6cSAndreas GohrIn addition, mere aggregation of another work not based on the Program 130*a3092f6cSAndreas Gohrwith the Program (or with a work based on the Program) on a volume of 131*a3092f6cSAndreas Gohra storage or distribution medium does not bring the other work under 132*a3092f6cSAndreas Gohrthe scope of this License. 133*a3092f6cSAndreas Gohr 134*a3092f6cSAndreas Gohr 3. You may copy and distribute the Program (or a work based on it, 135*a3092f6cSAndreas Gohrunder Section 2) in object code or executable form under the terms of 136*a3092f6cSAndreas GohrSections 1 and 2 above provided that you also do one of the following: 137*a3092f6cSAndreas Gohr 138*a3092f6cSAndreas Gohr a) Accompany it with the complete corresponding machine-readable 139*a3092f6cSAndreas Gohr source code, which must be distributed under the terms of Sections 140*a3092f6cSAndreas Gohr 1 and 2 above on a medium customarily used for software interchange; or, 141*a3092f6cSAndreas Gohr 142*a3092f6cSAndreas Gohr b) Accompany it with a written offer, valid for at least three 143*a3092f6cSAndreas Gohr years, to give any third party, for a charge no more than your 144*a3092f6cSAndreas Gohr cost of physically performing source distribution, a complete 145*a3092f6cSAndreas Gohr machine-readable copy of the corresponding source code, to be 146*a3092f6cSAndreas Gohr distributed under the terms of Sections 1 and 2 above on a medium 147*a3092f6cSAndreas Gohr customarily used for software interchange; or, 148*a3092f6cSAndreas Gohr 149*a3092f6cSAndreas Gohr c) Accompany it with the information you received as to the offer 150*a3092f6cSAndreas Gohr to distribute corresponding source code. (This alternative is 151*a3092f6cSAndreas Gohr allowed only for noncommercial distribution and only if you 152*a3092f6cSAndreas Gohr received the program in object code or executable form with such 153*a3092f6cSAndreas Gohr an offer, in accord with Subsection b above.) 154*a3092f6cSAndreas Gohr 155*a3092f6cSAndreas GohrThe source code for a work means the preferred form of the work for 156*a3092f6cSAndreas Gohrmaking modifications to it. For an executable work, complete source 157*a3092f6cSAndreas Gohrcode means all the source code for all modules it contains, plus any 158*a3092f6cSAndreas Gohrassociated interface definition files, plus the scripts used to 159*a3092f6cSAndreas Gohrcontrol compilation and installation of the executable. However, as a 160*a3092f6cSAndreas Gohrspecial exception, the source code distributed need not include 161*a3092f6cSAndreas Gohranything that is normally distributed (in either source or binary 162*a3092f6cSAndreas Gohrform) with the major components (compiler, kernel, and so on) of the 163*a3092f6cSAndreas Gohroperating system on which the executable runs, unless that component 164*a3092f6cSAndreas Gohritself accompanies the executable. 165*a3092f6cSAndreas Gohr 166*a3092f6cSAndreas GohrIf distribution of executable or object code is made by offering 167*a3092f6cSAndreas Gohraccess to copy from a designated place, then offering equivalent 168*a3092f6cSAndreas Gohraccess to copy the source code from the same place counts as 169*a3092f6cSAndreas Gohrdistribution of the source code, even though third parties are not 170*a3092f6cSAndreas Gohrcompelled to copy the source along with the object code. 171*a3092f6cSAndreas Gohr 172*a3092f6cSAndreas Gohr 4. You may not copy, modify, sublicense, or distribute the Program 173*a3092f6cSAndreas Gohrexcept as expressly provided under this License. Any attempt 174*a3092f6cSAndreas Gohrotherwise to copy, modify, sublicense or distribute the Program is 175*a3092f6cSAndreas Gohrvoid, and will automatically terminate your rights under this License. 176*a3092f6cSAndreas GohrHowever, parties who have received copies, or rights, from you under 177*a3092f6cSAndreas Gohrthis License will not have their licenses terminated so long as such 178*a3092f6cSAndreas Gohrparties remain in full compliance. 179*a3092f6cSAndreas Gohr 180*a3092f6cSAndreas Gohr 5. You are not required to accept this License, since you have not 181*a3092f6cSAndreas Gohrsigned it. However, nothing else grants you permission to modify or 182*a3092f6cSAndreas Gohrdistribute the Program or its derivative works. These actions are 183*a3092f6cSAndreas Gohrprohibited by law if you do not accept this License. Therefore, by 184*a3092f6cSAndreas Gohrmodifying or distributing the Program (or any work based on the 185*a3092f6cSAndreas GohrProgram), you indicate your acceptance of this License to do so, and 186*a3092f6cSAndreas Gohrall its terms and conditions for copying, distributing or modifying 187*a3092f6cSAndreas Gohrthe Program or works based on it. 188*a3092f6cSAndreas Gohr 189*a3092f6cSAndreas Gohr 6. Each time you redistribute the Program (or any work based on the 190*a3092f6cSAndreas GohrProgram), the recipient automatically receives a license from the 191*a3092f6cSAndreas Gohroriginal licensor to copy, distribute or modify the Program subject to 192*a3092f6cSAndreas Gohrthese terms and conditions. You may not impose any further 193*a3092f6cSAndreas Gohrrestrictions on the recipients' exercise of the rights granted herein. 194*a3092f6cSAndreas GohrYou are not responsible for enforcing compliance by third parties to 195*a3092f6cSAndreas Gohrthis License. 196*a3092f6cSAndreas Gohr 197*a3092f6cSAndreas Gohr 7. If, as a consequence of a court judgment or allegation of patent 198*a3092f6cSAndreas Gohrinfringement or for any other reason (not limited to patent issues), 199*a3092f6cSAndreas Gohrconditions are imposed on you (whether by court order, agreement or 200*a3092f6cSAndreas Gohrotherwise) that contradict the conditions of this License, they do not 201*a3092f6cSAndreas Gohrexcuse you from the conditions of this License. If you cannot 202*a3092f6cSAndreas Gohrdistribute so as to satisfy simultaneously your obligations under this 203*a3092f6cSAndreas GohrLicense and any other pertinent obligations, then as a consequence you 204*a3092f6cSAndreas Gohrmay not distribute the Program at all. For example, if a patent 205*a3092f6cSAndreas Gohrlicense would not permit royalty-free redistribution of the Program by 206*a3092f6cSAndreas Gohrall those who receive copies directly or indirectly through you, then 207*a3092f6cSAndreas Gohrthe only way you could satisfy both it and this License would be to 208*a3092f6cSAndreas Gohrrefrain entirely from distribution of the Program. 209*a3092f6cSAndreas Gohr 210*a3092f6cSAndreas GohrIf any portion of this section is held invalid or unenforceable under 211*a3092f6cSAndreas Gohrany particular circumstance, the balance of the section is intended to 212*a3092f6cSAndreas Gohrapply and the section as a whole is intended to apply in other 213*a3092f6cSAndreas Gohrcircumstances. 214*a3092f6cSAndreas Gohr 215*a3092f6cSAndreas GohrIt is not the purpose of this section to induce you to infringe any 216*a3092f6cSAndreas Gohrpatents or other property right claims or to contest validity of any 217*a3092f6cSAndreas Gohrsuch claims; this section has the sole purpose of protecting the 218*a3092f6cSAndreas Gohrintegrity of the free software distribution system, which is 219*a3092f6cSAndreas Gohrimplemented by public license practices. Many people have made 220*a3092f6cSAndreas Gohrgenerous contributions to the wide range of software distributed 221*a3092f6cSAndreas Gohrthrough that system in reliance on consistent application of that 222*a3092f6cSAndreas Gohrsystem; it is up to the author/donor to decide if he or she is willing 223*a3092f6cSAndreas Gohrto distribute software through any other system and a licensee cannot 224*a3092f6cSAndreas Gohrimpose that choice. 225*a3092f6cSAndreas Gohr 226*a3092f6cSAndreas GohrThis section is intended to make thoroughly clear what is believed to 227*a3092f6cSAndreas Gohrbe a consequence of the rest of this License. 228*a3092f6cSAndreas Gohr 229*a3092f6cSAndreas Gohr 8. If the distribution and/or use of the Program is restricted in 230*a3092f6cSAndreas Gohrcertain countries either by patents or by copyrighted interfaces, the 231*a3092f6cSAndreas Gohroriginal copyright holder who places the Program under this License 232*a3092f6cSAndreas Gohrmay add an explicit geographical distribution limitation excluding 233*a3092f6cSAndreas Gohrthose countries, so that distribution is permitted only in or among 234*a3092f6cSAndreas Gohrcountries not thus excluded. In such case, this License incorporates 235*a3092f6cSAndreas Gohrthe limitation as if written in the body of this License. 236*a3092f6cSAndreas Gohr 237*a3092f6cSAndreas Gohr 9. The Free Software Foundation may publish revised and/or new versions 238*a3092f6cSAndreas Gohrof the General Public License from time to time. Such new versions will 239*a3092f6cSAndreas Gohrbe similar in spirit to the present version, but may differ in detail to 240*a3092f6cSAndreas Gohraddress new problems or concerns. 241*a3092f6cSAndreas Gohr 242*a3092f6cSAndreas GohrEach version is given a distinguishing version number. If the Program 243*a3092f6cSAndreas Gohrspecifies a version number of this License which applies to it and "any 244*a3092f6cSAndreas Gohrlater version", you have the option of following the terms and conditions 245*a3092f6cSAndreas Gohreither of that version or of any later version published by the Free 246*a3092f6cSAndreas GohrSoftware Foundation. If the Program does not specify a version number of 247*a3092f6cSAndreas Gohrthis License, you may choose any version ever published by the Free Software 248*a3092f6cSAndreas GohrFoundation. 249*a3092f6cSAndreas Gohr 250*a3092f6cSAndreas Gohr 10. If you wish to incorporate parts of the Program into other free 251*a3092f6cSAndreas Gohrprograms whose distribution conditions are different, write to the author 252*a3092f6cSAndreas Gohrto ask for permission. For software which is copyrighted by the Free 253*a3092f6cSAndreas GohrSoftware Foundation, write to the Free Software Foundation; we sometimes 254*a3092f6cSAndreas Gohrmake exceptions for this. Our decision will be guided by the two goals 255*a3092f6cSAndreas Gohrof preserving the free status of all derivatives of our free software and 256*a3092f6cSAndreas Gohrof promoting the sharing and reuse of software generally. 257*a3092f6cSAndreas Gohr 258*a3092f6cSAndreas Gohr NO WARRANTY 259*a3092f6cSAndreas Gohr 260*a3092f6cSAndreas Gohr 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261*a3092f6cSAndreas GohrFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262*a3092f6cSAndreas GohrOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263*a3092f6cSAndreas GohrPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264*a3092f6cSAndreas GohrOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265*a3092f6cSAndreas GohrMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 266*a3092f6cSAndreas GohrTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 267*a3092f6cSAndreas GohrPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 268*a3092f6cSAndreas GohrREPAIR OR CORRECTION. 269*a3092f6cSAndreas Gohr 270*a3092f6cSAndreas Gohr 12.

It is safest 289*a3092f6cSAndreas Gohrto attach them to the start of each source file to most effectively 290*a3092f6cSAndreas Gohrconvey the exclusion of warranty; and each file should have at least 291*a3092f6cSAndreas Gohrthe "copyright" line and a pointer to where the full notice is found. 292*a3092f6cSAndreas Gohr 293*a3092f6cSAndreas Gohr <one line to give the program's name and a brief idea of what it does.> 294*a3092f6cSAndreas Gohr Copyright (C) <year> <name of author> 295*a3092f6cSAndreas Gohr 296*a3092f6cSAndreas Gohr This program is free software; you can redistribute it and/or modify 297*a3092f6cSAndreas Gohr it under the terms of the GNU General Public License as published by 298*a3092f6cSAndreas Gohr the Free Software Foundation; either version 2 of the License, or 299*a3092f6cSAndreas Gohr (at your option) any later version. 300*a3092f6cSAndreas Gohr 301*a3092f6cSAndreas Gohr This program is distributed in the hope that it will be useful, 302*a3092f6cSAndreas Gohr but WITHOUT ANY WARRANTY; without even the implied warranty of 303*a3092f6cSAndreas Gohr MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
