# 'clock' -- A simple alarm clock
# The alarm can be set at 5 minute intervals on a 12 hour basis.
# It is controlled with the mouse:
# - Click and drag around the circle to set the alarm.
# - Click far outside the circle to clear the alarm.
# - Click near the center to set the alarm at the last time set.
# The alarm time is indicated by a small triangle just outside the circle,
# and also by a digital time at the bottom.
# The indicators disappear when the alarm is not set.
# When the alarm goes off, it beeps every minute for five minutes,
# and the clock turns into inverse video.
# Click or activate the window to turn the ringing off.
