HANGMAN FOR JAVA
(c)1998/99 by Markus Birth <Robo.Cop(a)gmx.net>

This is the first program I wrote in Java. Thanks to
Mr. Fröbel for making me learning Java so quick (We had to
finish our projects for the computer science lessons.)

Things used for the making of this:
-Xemacs with its Revision Control System
-hangman.java from Carlos von Hoyningen-Huene
-some bottles of PEPSI Coke
-hints & tips from Carlos von Hoyningen-Huene
