-      The Gnubik program is an interactive, graphical, single player
-      puzzle. Yes, this is another implementation of the classic game
-      like that invented by Erno Rubik. You have to manipulate the
-      cube using the mouse. When each face shows only one colour, the
-      game is solved.
-
-      Gnubik is written in C and Guile. The latter allows you to
-      extend the program using the Scheme language — a simple
-      programming tool which even novice computer users can use. For
-      example, you can use Scheme to write your own automated solving
-      routines or to create patterns.
