   970 		       Version 2, June 1991 

   971 

   972  Copyright (C) 1989, 1991 Free Software Foundation, Inc. 

   973                        59 Temple Place, Suite 330, Boston, MA  02111-1307  USA 

   974  Everyone is permitted to copy and distribute verbatim copies 

   975  of this license document, but changing it is not allowed. 

   976 

   977 			    Preamble 

   978 

   979   The licenses for most software are designed to take away your 

   980 freedom to share and change it.  By contrast, the GNU General Public 

   981 License is intended to guarantee your freedom to share and change free 

   982 software--to make sure the software is free for all its users.  This 

   983 General Public License applies to most of the Free Software 

   984 Foundation's software and to any other program whose authors commit to 

   985 using it.  (Some other Free Software Foundation software is covered by 

   986 the GNU Library General Public License instead.)  You can apply it to 

   987 your programs, too. 

   988 

   989   When we speak of free software, we are referring to freedom, not 

   990 price.  Our General Public Licenses are designed to make sure that you 

   991 have the freedom to distribute copies of free software (and charge for 

   992 this service if you wish), that you receive source code or can get it 

   993 if you want it, that you can change the software or use pieces of it 

   994 in new free programs; and that you know you can do these things. 

   995 

   996   To protect your rights, we need to make restrictions that forbid 

   997 anyone to deny you these rights or to ask you to surrender the rights. 

   998 These restrictions translate to certain responsibilities for you if you 

   999 distribute copies of the software, or if you modify it. 

  1000 

  1001   For example, if you distribute copies of such a program, whether 

  1002 gratis or for a fee, you must give the recipients all the rights that 

  1003 you have.  You must make sure that they, too, receive or can get the 

  1004 source code.  And you must show them these terms so they know their 

  1005 rights. 

  1006 

  1007   We protect your rights with two steps: (1) copyright the software, and 

  1008 (2) offer you this license which gives you legal permission to copy, 

  1009 distribute and/or modify the software. 

  1010 

  1011   Also, for each author's protection and ours, we want to make certain 

  1012 that everyone understands that there is no warranty for this free 

  1013 software.  If the software is modified by someone else and passed on, we 

  1014 want its recipients to know that what they have is not the original, so 

  1015 that any problems introduced by others will not reflect on the original 

  1016 authors' reputations. 

  1017 

  1018   Finally, any free program is threatened constantly by software 

  1019 patents.  We wish to avoid the danger that redistributors of a free 

  1020 program will individually obtain patent licenses, in effect making the 

  1021 program proprietary.  To prevent this, we have made it clear that any 

  1022 patent must be licensed for everyone's free use or not licensed at all. 

  1023 

  1024   The precise terms and conditions for copying, distribution and 

  1025 modification follow. 

  1026 

  1027 

  1028 		    GNU GENERAL PUBLIC LICENSE 

  1029    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 

  1030 

  1031   0. This License applies to any program or other work which contains 

  1032 a notice placed by the copyright holder saying it may be distributed 

  1033 under the terms of this General Public License.  The "Program", below, 

  1034 refers to any such program or work, and a "work based on the Program" 

  1035 means either the Program or any derivative work under copyright law: 

  1036 that is to say, a work containing the Program or a portion of it, 

  1037 either verbatim or with modifications and/or translated into another 

  1038 language.  (Hereinafter, translation is included without limitation in 

  1039 the term "modification".)  Each licensee is addressed as "you". 

  1040 

  1041 Activities other than copying, distribution and modification are not 

  1042 covered by this License; they are outside its scope.  The act of 

  1043 running the Program is not restricted, and the output from the Program 

  1044 is covered only if its contents constitute a work based on the 

  1045 Program (independent of having been made by running the Program). 

  1046 Whether that is true depends on what the Program does. 

  1047 

  1048   1. You may copy and distribute verbatim copies of the Program's 

  1049 source code as you receive it, in any medium, provided that you 

  1050 conspicuously and appropriately publish on each copy an appropriate 

  1051 copyright notice and disclaimer of warranty; keep intact all the 

  1052 notices that refer to this License and to the absence of any warranty; 

  1053 and give any other recipients of the Program a copy of this License 

  1054 along with the Program. 

  1055 

  1056 You may charge a fee for the physical act of transferring a copy, and 

  1057 you may at your option offer warranty protection in exchange for a fee. 

  1058  

  1059   2. You may modify your copy or copies of the Program or any portion 

  1060 of it, thus forming a work based on the Program, and copy and 

  1061 distribute such modifications or work under the terms of Section 1 

  1062 above, provided that you also meet all of these conditions: 

  1063 

  1064     a) You must cause the modified files to carry prominent notices 

  1065     stating that you changed the files and the date of any change. 

  1066 

  1067     b) You must cause any work that you distribute or publish, that in 

  1068     whole or in part contains or is derived from the Program or any 

  1069     part thereof, to be licensed as a whole at no charge to all third 

  1070     parties under the terms of this License. 

  1071 

  1072     c) If the modified program normally reads commands interactively 

  1073     when run, you must cause it, when started running for such 

  1074     interactive use in the most ordinary way, to print or display an 

  1075     announcement including an appropriate copyright notice and a 

  1076     notice that there is no warranty (or else, saying that you provide 

  1077     a warranty) and that users may redistribute the program under 

  1078     these conditions, and telling the user how to view a copy of this 

  1079     License.  (Exception: if the Program itself is interactive but 

  1080     does not normally print such an announcement, your work based on 

  1081     the Program is not required to print an announcement.) 

  1082 

  1083 

  1084 These requirements apply to the modified work as a whole.  If 

  1085 identifiable sections of that work are not derived from the Program, 

  1086 and can be reasonably considered independent and separate works in 

  1087 themselves, then this License, and its terms, do not apply to those 

  1088 sections when you distribute them as separate works.  But when you 

  1089 distribute the same sections as part of a whole which is a work based 

  1090 on the Program, the distribution of the whole must be on the terms of 

  1091 this License, whose permissions for other licensees extend to the 

  1092 entire whole, and thus to each and every part regardless of who wrote it. 

  1093 

  1094 Thus, it is not the intent of this section to claim rights or contest 

  1095 your rights to work written entirely by you; rather, the intent is to 

  1096 exercise the right to control the distribution of derivative or 

  1097 collective works based on the Program. 

  1098 

  1099 In addition, mere aggregation of another work not based on the Program 

  1100 with the Program (or with a work based on the Program) on a volume of 

  1101 a storage or distribution medium does not bring the other work under 

  1102 the scope of this License. 

  1103 

  1104   3. You may copy and distribute the Program (or a work based on it, 

  1105 under Section 2) in object code or executable form under the terms of 

  1106 Sections 1 and 2 above provided that you also do one of the following: 

  1107 

  1108     a) Accompany it with the complete corresponding machine-readable 

  1109     source code, which must be distributed under the terms of Sections 

  1110     1 and 2 above on a medium customarily used for software interchange; or, 

  1111 

  1112     b) Accompany it with a written offer, valid for at least three 

  1113     years, to give any third party, for a charge no more than your 

  1114     cost of physically performing source distribution, a complete 

  1115     machine-readable copy of the corresponding source code, to be 

  1116     distributed under the terms of Sections 1 and 2 above on a medium 

  1117     customarily used for software interchange; or, 

  1118 

  1119     c) Accompany it with the information you received as to the offer 

  1120     to distribute corresponding source code.  (This alternative is 

  1121     allowed only for noncommercial distribution and only if you 

  1122     received the program in object code or executable form with such 

  1123     an offer, in accord with Subsection b above.) 

  1124 

  1125 The source code for a work means the preferred form of the work for 

  1126 making modifications to it.  For an executable work, complete source 

  1127 code means all the source code for all modules it contains, plus any 

  1128 associated interface definition files, plus the scripts used to
