# dice / A RP Dice Simulator
#
# What is this?
#
# I often Dungeon Master on our Neverwinternights Servers called "Bund der
# alten Reiche" (eng. "Alliance of the old realms") at bundderaltenreiche.de
# (German Site) Often idling in our Channel I thought it might be Fun to have 
# a script to dice. Since I found nothing for irssi I wrote this little piece
# of script. The script assumes, that if a 'd' for english dice is given it 
# should print the output in english. On the other hand if a 'w' for german 
# "Würfel" is given it prints the output in german. 
#
# Usage.
#
# Anyone on the Channel kann ask "!dice" to toss the dice for him. He just has
# to say what dice he want to use. The notation should be well known from
# RP :-) Thus
# 
# Write: !dice: <quantity of dice>d[or w for german users]<sides on dice>
#
# Here are some examples
# 
# !dice: 2d20
# !dice: 3d6
#
# OK, I think you got it already :-)
#
# Write: !dice version 
# For Version Information
#
# Write: !dice help
# For Information about how to use it
