# Run this every minute (for example using cron) to receive a notification
# when an event happens.
#
# The events are read from the following files in SDEPDATA folder:
#	once: events that only happen once; full date needs to be specified
#	daily: events that happen every day; only specify the time in HH:MM format
#	weekly: only specify Weekday + time
#	monthly: only specify day of the month + time

# Requires: a command to send notifications such as herbe or notify-send.
# The weekly part uses the non-portable -d option of GNU date, which you
# might have to change if you are not on Linux (on some systems you can
# accomplish the same with -j).
