#8-ball / decision ball
#
#What is this?
#
#The 8-ball (Eight-ball) is a decision ball which i bought
#in a gadget shop when i was in London. I then came up with 
#the idea to make an irc-version of this one :)
#There are 16 possible answers that the ball may give you.
#
#
#usage   
#
#Anyone in the same channel as the one who runs this script may
#write "8-ball: question ?" without quotes and where question is
#a question to ask the 8-ball. 
#An answer is given randomly. The possible answers are the exact
#same answers that the real 8-ball gives.
#
#Write "8-ball" without quotes to have the the ball tell you
#how money questions it've got totally.
#
#Write "8-ball version" without quotes to have him tell what
#his version is.
