1*34b8413fStracker-user GNU GENERAL PUBLIC LICENSE 2*34b8413fStracker-user Version 2, June 1991 3*34b8413fStracker-user 4*34b8413fStracker-user Copyright (C) 1989, 1991 Free Software Foundation, Inc., 5*34b8413fStracker-user 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA 6*34b8413fStracker-user Everyone is permitted to copy and distribute verbatim copies 7*34b8413fStracker-user of this license document, but changing it is not allowed. 8*34b8413fStracker-user 9*34b8413fStracker-user Preamble 10*34b8413fStracker-user 11*34b8413fStracker-user The licenses for most software are designed to take away your 12*34b8413fStracker-userfreedom to share and change it. By contrast, the GNU General Public 13*34b8413fStracker-userLicense is intended to guarantee your freedom to share and change free 14*34b8413fStracker-usersoftware--to make sure the software is free for all its users. This 15*34b8413fStracker-userGeneral Public License applies to most of the Free Software 16*34b8413fStracker-userFoundation's software and to any other program whose authors commit to 17*34b8413fStracker-userusing it. (Some other Free Software Foundation software is covered by 18*34b8413fStracker-userthe GNU Lesser General Public License instead.) You can apply it to 19*34b8413fStracker-useryour programs, too. 20*34b8413fStracker-user 21*34b8413fStracker-user When we speak of free software, we are referring to freedom, not 22*34b8413fStracker-userprice. Our General Public Licenses are designed to make sure that you 23*34b8413fStracker-userhave the freedom to distribute copies of free software (and charge for 24*34b8413fStracker-userthis service if you wish), that you receive source code or can get it 25*34b8413fStracker-userif you want it, that you can change the software or use pieces of it 26*34b8413fStracker-userin new free programs; and that you know you can do these things. 27*34b8413fStracker-user 28*34b8413fStracker-user To protect your rights, we need to make restrictions that forbid 29*34b8413fStracker-useranyone to deny you these rights or to ask you to surrender the rights. 30*34b8413fStracker-userThese restrictions translate to certain responsibilities for you if you 31*34b8413fStracker-userdistribute copies of the software, or if you modify it. 32*34b8413fStracker-user 33*34b8413fStracker-user For example, if you distribute copies of such a program, whether 34*34b8413fStracker-usergratis or for a fee, you must give the recipients all the rights that 35*34b8413fStracker-useryou have. You must make sure that they, too, receive or can get the 36*34b8413fStracker-usersource code. And you must show them these terms so they know their 37*34b8413fStracker-userrights. 38*34b8413fStracker-user 39*34b8413fStracker-user We protect your rights with two steps: (1) copyright the software, and 40*34b8413fStracker-user(2) offer you this license which gives you legal permission to copy, 41*34b8413fStracker-userdistribute and/or modify the software. 42*34b8413fStracker-user 43*34b8413fStracker-user Also, for each author's protection and ours, we want to make certain 44*34b8413fStracker-userthat everyone understands that there is no warranty for this free 45*34b8413fStracker-usersoftware. If the software is modified by someone else and passed on, we 46*34b8413fStracker-userwant its recipients to know that what they have is not the original, so 47*34b8413fStracker-userthat any problems introduced by others will not reflect on the original 48*34b8413fStracker-userauthors' reputations. 49*34b8413fStracker-user 50*34b8413fStracker-user Finally, any free program is threatened constantly by software 51*34b8413fStracker-userpatents. We wish to avoid the danger that redistributors of a free 52*34b8413fStracker-userprogram will individually obtain patent licenses, in effect making the 53*34b8413fStracker-userprogram proprietary. To prevent this, we have made it clear that any 54*34b8413fStracker-userpatent must be licensed for everyone's free use or not licensed at all. 55*34b8413fStracker-user 56*34b8413fStracker-user The precise terms and conditions for copying, distribution and 57*34b8413fStracker-usermodification follow. 58*34b8413fStracker-user 59*34b8413fStracker-user GNU GENERAL PUBLIC LICENSE 60*34b8413fStracker-user TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 61*34b8413fStracker-user 62*34b8413fStracker-user 0. This License applies to any program or other work which contains 63*34b8413fStracker-usera notice placed by the copyright holder saying it may be distributed 64*34b8413fStracker-userunder the terms of this General Public License. The "Program", below, 65*34b8413fStracker-userrefers to any such program or work, and a "work based on the Program" 66*34b8413fStracker-usermeans either the Program or any derivative work under copyright law: 67*34b8413fStracker-userthat is to say, a work containing the Program or a portion of it, 68*34b8413fStracker-usereither verbatim or with modifications and/or translated into another 69*34b8413fStracker-userlanguage. (Hereinafter, translation is included without limitation in 70*34b8413fStracker-userthe term "modification".) Each licensee is addressed as "you". 71*34b8413fStracker-user 72*34b8413fStracker-userActivities other than copying, distribution and modification are not 73*34b8413fStracker-usercovered by this License; they are outside its scope. The act of 74*34b8413fStracker-userrunning the Program is not restricted, and the output from the Program 75*34b8413fStracker-useris covered only if its contents constitute a work based on the 76*34b8413fStracker-userProgram (independent of having been made by running the Program). 77*34b8413fStracker-userWhether that is true depends on what the Program does. 78*34b8413fStracker-user 79*34b8413fStracker-user 1. You may copy and distribute verbatim copies of the Program's 80*34b8413fStracker-usersource code as you receive it, in any medium, provided that you 81*34b8413fStracker-userconspicuously and appropriately publish on each copy an appropriate 82*34b8413fStracker-usercopyright notice and disclaimer of warranty; keep intact all the 83*34b8413fStracker-usernotices that refer to this License and to the absence of any warranty; 84*34b8413fStracker-userand give any other recipients of the Program a copy of this License 85*34b8413fStracker-useralong with the Program. 86*34b8413fStracker-user 87*34b8413fStracker-userYou may charge a fee for the physical act of transferring a copy, and 88*34b8413fStracker-useryou may at your option offer warranty protection in exchange for a fee. 89*34b8413fStracker-user 90*34b8413fStracker-user 2. You may modify your copy or copies of the Program or any portion 91*34b8413fStracker-userof it, thus forming a work based on the Program, and copy and 92*34b8413fStracker-userdistribute such modifications or work under the terms of Section 1 93*34b8413fStracker-userabove, provided that you also meet all of these conditions: 94*34b8413fStracker-user 95*34b8413fStracker-user a) You must cause the modified files to carry prominent notices 96*34b8413fStracker-user stating that you changed the files and the date of any change. 97*34b8413fStracker-user 98*34b8413fStracker-user b) You must cause any work that you distribute or publish, that in 99*34b8413fStracker-user whole or in part contains or is derived from the Program or any 100*34b8413fStracker-user part thereof, to be licensed as a whole at no charge to all third 101*34b8413fStracker-user parties under the terms of this License. 102*34b8413fStracker-user 103*34b8413fStracker-user c) If the modified program normally reads commands interactively 104*34b8413fStracker-user when run, you must cause it, when started running for such 105*34b8413fStracker-user interactive use in the most ordinary way, to print or display an 106*34b8413fStracker-user announcement including an appropriate copyright notice and a 107*34b8413fStracker-user notice that there is no warranty (or else, saying that you provide 108*34b8413fStracker-user a warranty) and that users may redistribute the program under 109*34b8413fStracker-user these conditions, and telling the user how to view a copy of this 110*34b8413fStracker-user License. (Exception: if the Program itself is interactive but 111*34b8413fStracker-user does not normally print such an announcement, your work based on 112*34b8413fStracker-user the Program is not required to print an announcement.) 113*34b8413fStracker-user 114*34b8413fStracker-userThese requirements apply to the modified work as a whole. If 115*34b8413fStracker-useridentifiable sections of that work are not derived from the Program, 116*34b8413fStracker-userand can be reasonably considered independent and separate works in 117*34b8413fStracker-userthemselves, then this License, and its terms, do not apply to those 118*34b8413fStracker-usersections when you distribute them as separate works. But when you 119*34b8413fStracker-userdistribute the same sections as part of a whole which is a work based 120*34b8413fStracker-useron the Program, the distribution of the whole must be on the terms of 121*34b8413fStracker-userthis License, whose permissions for other licensees extend to the 122*34b8413fStracker-userentire whole, and thus to each and every part regardless of who wrote it. 123*34b8413fStracker-user 124*34b8413fStracker-userThus, it is not the intent of this section to claim rights or contest 125*34b8413fStracker-useryour rights to work written entirely by you; rather, the intent is to 126*34b8413fStracker-userexercise the right to control the distribution of derivative or 127*34b8413fStracker-usercollective works based on the Program. 128*34b8413fStracker-user 129*34b8413fStracker-userIn addition, mere aggregation of another work not based on the Program 130*34b8413fStracker-userwith the Program (or with a work based on the Program) on a volume of 131*34b8413fStracker-usera storage or distribution medium does not bring the other work under 132*34b8413fStracker-userthe scope of this License. 133*34b8413fStracker-user 134*34b8413fStracker-user 3. You may copy and distribute the Program (or a work based on it, 135*34b8413fStracker-userunder Section 2) in object code or executable form under the terms of 136*34b8413fStracker-userSections 1 and 2 above provided that you also do one of the following: 137*34b8413fStracker-user 138*34b8413fStracker-user a) Accompany it with the complete corresponding machine-readable 139*34b8413fStracker-user source code, which must be distributed under the terms of Sections 140*34b8413fStracker-user 1 and 2 above on a medium customarily used for software interchange; or, 141*34b8413fStracker-user 142*34b8413fStracker-user b) Accompany it with a written offer, valid for at least three 143*34b8413fStracker-user years, to give any third party, for a charge no more than your 144*34b8413fStracker-user cost of physically performing source distribution, a complete 145*34b8413fStracker-user machine-readable copy of the corresponding source code, to be 146*34b8413fStracker-user distributed under the terms of Sections 1 and 2 above on a medium 147*34b8413fStracker-user customarily used for software interchange; or, 148*34b8413fStracker-user 149*34b8413fStracker-user c) Accompany it with the information you received as to the offer 150*34b8413fStracker-user to distribute corresponding source code. (This alternative is 151*34b8413fStracker-user allowed only for noncommercial distribution and only if you 152*34b8413fStracker-user received the program in object code or executable form with such 153*34b8413fStracker-user an offer, in accord with Subsection b above.) 154*34b8413fStracker-user 155*34b8413fStracker-userThe source code for a work means the preferred form of the work for 156*34b8413fStracker-usermaking modifications to it. For an executable work, complete source 157*34b8413fStracker-usercode means all the source code for all modules it contains, plus any 158*34b8413fStracker-userassociated interface definition files, plus the scripts used to 159*34b8413fStracker-usercontrol compilation and installation of the executable. However, as a 160*34b8413fStracker-userspecial exception, the source code distributed need not include 161*34b8413fStracker-useranything that is normally distributed (in either source or binary 162*34b8413fStracker-userform) with the major components (compiler, kernel, and so on) of the 163*34b8413fStracker-useroperating system on which the executable runs, unless that component 164*34b8413fStracker-useritself accompanies the executable. 165*34b8413fStracker-user 166*34b8413fStracker-userIf distribution of executable or object code is made by offering 167*34b8413fStracker-useraccess to copy from a designated place, then offering equivalent 168*34b8413fStracker-useraccess to copy the source code from the same place counts as 169*34b8413fStracker-userdistribution of the source code, even though third parties are not 170*34b8413fStracker-usercompelled to copy the source along with the object code. 171*34b8413fStracker-user 172*34b8413fStracker-user 4. You may not copy, modify, sublicense, or distribute the Program 173*34b8413fStracker-userexcept as expressly provided under this License. Any attempt 174*34b8413fStracker-userotherwise to copy, modify, sublicense or distribute the Program is 175*34b8413fStracker-uservoid, and will automatically terminate your rights under this License. 176*34b8413fStracker-userHowever, parties who have received copies, or rights, from you under 177*34b8413fStracker-userthis License will not have their licenses terminated so long as such 178*34b8413fStracker-userparties remain in full compliance. 179*34b8413fStracker-user 180*34b8413fStracker-user 5. You are not required to accept this License, since you have not 181*34b8413fStracker-usersigned it. However, nothing else grants you permission to modify or 182*34b8413fStracker-userdistribute the Program or its derivative works. These actions are 183*34b8413fStracker-userprohibited by law if you do not accept this License. Therefore, by 184*34b8413fStracker-usermodifying or distributing the Program (or any work based on the 185*34b8413fStracker-userProgram), you indicate your acceptance of this License to do so, and 186*34b8413fStracker-userall its terms and conditions for copying, distributing or modifying 187*34b8413fStracker-userthe Program or works based on it. 188*34b8413fStracker-user 189*34b8413fStracker-user 6. Each time you redistribute the Program (or any work based on the 190*34b8413fStracker-userProgram), the recipient automatically receives a license from the 191*34b8413fStracker-useroriginal licensor to copy, distribute or modify the Program subject to 192*34b8413fStracker-userthese terms and conditions. You may not impose any further 193*34b8413fStracker-userrestrictions on the recipients' exercise of the rights granted herein. 194*34b8413fStracker-userYou are not responsible for enforcing compliance by third parties to 195*34b8413fStracker-userthis License. 196*34b8413fStracker-user 197*34b8413fStracker-user 7. If, as a consequence of a court judgment or allegation of patent 198*34b8413fStracker-userinfringement or for any other reason (not limited to patent issues), 199*34b8413fStracker-userconditions are imposed on you (whether by court order, agreement or 200*34b8413fStracker-userotherwise) that contradict the conditions of this License, they do not 201*34b8413fStracker-userexcuse you from the conditions of this License. If you cannot 202*34b8413fStracker-userdistribute so as to satisfy simultaneously your obligations under this 203*34b8413fStracker-userLicense and any other pertinent obligations, then as a consequence you 204*34b8413fStracker-usermay not distribute the Program at all. For example, if a patent 205*34b8413fStracker-userlicense would not permit royalty-free redistribution of the Program by 206*34b8413fStracker-userall those who receive copies directly or indirectly through you, then 207*34b8413fStracker-userthe only way you could satisfy both it and this License would be to 208*34b8413fStracker-userrefrain entirely from distribution of the Program. 209*34b8413fStracker-user 210*34b8413fStracker-userIf any portion of this section is held invalid or unenforceable under 211*34b8413fStracker-userany particular circumstance, the balance of the section is intended to 212*34b8413fStracker-userapply and the section as a whole is intended to apply in other 213*34b8413fStracker-usercircumstances. 214*34b8413fStracker-user 215*34b8413fStracker-userIt is not the purpose of this section to induce you to infringe any 216*34b8413fStracker-userpatents or other property right claims or to contest validity of any 217*34b8413fStracker-usersuch claims; this section has the sole purpose of protecting the 218*34b8413fStracker-userintegrity of the free software distribution system, which is 219*34b8413fStracker-userimplemented by public license practices. Many people have made 220*34b8413fStracker-usergenerous contributions to the wide range of software distributed 221*34b8413fStracker-userthrough that system in reliance on consistent application of that 222*34b8413fStracker-usersystem; it is up to the author/donor to decide if he or she is willing 223*34b8413fStracker-userto distribute software through any other system and a licensee cannot 224*34b8413fStracker-userimpose that choice. 225*34b8413fStracker-user 226*34b8413fStracker-userThis section is intended to make thoroughly clear what is believed to 227*34b8413fStracker-userbe a consequence of the rest of this License. 228*34b8413fStracker-user 229*34b8413fStracker-user 8. If the distribution and/or use of the Program is restricted in 230*34b8413fStracker-usercertain countries either by patents or by copyrighted interfaces, the 231*34b8413fStracker-useroriginal copyright holder who places the Program under this License 232*34b8413fStracker-usermay add an explicit geographical distribution limitation excluding 233*34b8413fStracker-userthose countries, so that distribution is permitted only in or among 234*34b8413fStracker-usercountries not thus excluded. In such case, this License incorporates 235*34b8413fStracker-userthe limitation as if written in the body of this License. 236*34b8413fStracker-user 237*34b8413fStracker-user 9. The Free Software Foundation may publish revised and/or new versions 238*34b8413fStracker-userof the General Public License from time to time. Such new versions will 239*34b8413fStracker-userbe similar in spirit to the present version, but may differ in detail to 240*34b8413fStracker-useraddress new problems or concerns. 241*34b8413fStracker-user 242*34b8413fStracker-userEach version is given a distinguishing version number. If the Program 243*34b8413fStracker-userspecifies a version number of this License which applies to it and "any 244*34b8413fStracker-userlater version", you have the option of following the terms and conditions 245*34b8413fStracker-usereither of that version or of any later version published by the Free 246*34b8413fStracker-userSoftware Foundation. If the Program does not specify a version number of 247*34b8413fStracker-userthis License, you may choose any version ever published by the Free Software 248*34b8413fStracker-userFoundation. 249*34b8413fStracker-user 250*34b8413fStracker-user 10. If you wish to incorporate parts of the Program into other free 251*34b8413fStracker-userprograms whose distribution conditions are different, write to the author 252*34b8413fStracker-userto ask for permission. For software which is copyrighted by the Free 253*34b8413fStracker-userSoftware Foundation, write to the Free Software Foundation; we sometimes 254*34b8413fStracker-usermake exceptions for this. Our decision will be guided by the two goals 255*34b8413fStracker-userof preserving the free status of all derivatives of our free software and 256*34b8413fStracker-userof promoting the sharing and reuse of software generally. 257*34b8413fStracker-user 258*34b8413fStracker-user NO WARRANTY 259*34b8413fStracker-user 260*34b8413fStracker-user 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 261*34b8413fStracker-userFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 262*34b8413fStracker-userOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 263*34b8413fStracker-userPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 264*34b8413fStracker-userOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 265*34b8413fStracker-userMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 266*34b8413fStracker-userTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
