"""Hangman.py, a simple wxPython game, inspired by the 
old bsd game by Ken Arnold.
From the original man page:

 In hangman, the computer picks a word from the on-line 
 word list and you must try to guess it.  The computer 
 keeps track of which letters have been guessed and how 
 many wrong guesses you have made on the screen in a
 graphic fashion. 

That says it all, doesn't it?

Have fun with it,

Harm van der Heijden (H.v.d.Heijden@phys.tue.nl)"""
