#---------------------------------------
# Description
#---------------------------------------
#
# A fork of pyglet's timer.py. Thanks to Luke Macken and Alex Holkner.
#
# A full-screen hour:minute:second countdown timer.
#
# Specify two arguments when calling the script:
# e.g. timer.py [hours] [minutes]
# Hours must be specified in the 24-hour clock. (e.g. 10pm = 22)
#
#The script will then count down to that time on the current day. If that time is already past, it will count up in red.
