# "M Clock"
#
# An implementation in software of an original design by Rob Juda.
# Clock implementation: Guido van Rossum.
# Alarm and Gong features: Sape Mullender.
#
# XXX TO DO:
# add arguments to specify initial window position and size
# find out local time zone difference automatically
# add a date indicator
# allow multiple alarms
# allow the menu to change more parameters
