+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
