" Copyright (c) 1979, 1996, 1997 James L. Dean\n"+
"\n"+
" Version 4.4 released 3/13/97\n"+
"\n"+
" This program may be distributed or used without payment "+
"to its author.\n"+
"\n"+
" This ADVENTURE-like game was inspired by a program given "+
"by Roger Chaffee in his article \"Quest\" published in the "+
"July 1979 issue of Byte. Unlike that program, this program "+
"allows multiple treasures and play in four dimensions. In "+
"addition, at the beginning of a game, this program allows "+
"the player to specify a game number that changes the "+
"connections between the locations in an unpredictable "+
"manner. Thus, the player has a whole series of games at his "+
"disposal.\n"+
"\n"+
" The object of this game is to bring all the treasures to "+
"the starting point while visiting all the locations in the "+
"smallest number of moves. Hint: the distance from one room "+
"to the next is always the same.\n"+
"\n"+
" This program was originally written in 1979 in Basic for "+
"a TANO Corporation Outpost having 64K of memory. A later "+
"version was written in COBOL for CICS on an IBM Mainframe. "+
"This version is written in Java.";
