/*
* You may play this game and more on http://www.fantasi.se/
*
* You will also need the following images:
* dot.gif, dice.gif, hold.gif, newgame.gif, roll.gif, hiscore.gif
*
* To get the HiScore list working, you will need the Perl script yatzy.pl
* This script is called as a cgi and must be on a web server supporting
* cgi's. To play the game on a local host, the methods loadHiScore() and
* saveHiScore() need some rewriting to access a local file instead.
