Sokoban analyser by Victor Kindermans (October 27,2001)
Version 2.0 April 7,2002, 

inspired by Franois Marques' on line html solution analyser.

An explanation of each item is shown, when the mouse pointer hovers 
over the description label.

Changed on January 9, 2002: clicking on the label above the 
solution text box changes the LuRd format interpretation from
   "LuRd format with only lowercase letters for moves and only uppercase letters for pushes."
to
   "LuRd format, with lowercase and/or uppercase letters for moves as well as for pushes."
or vice versa.
In case of only lowercase letters for moves and only uppercase letters for pushes, the program
will ask you to correct the lettertype, each time it encounters an uppercase while a move but 
not a push can be done, and each time it encounters a lowercase while a push and not a simple 
move can be done.
