# BRIEF: Script to control dumb telnet-accessible power strips. Created with
# clean output for use in Home Assistant or other automation but could
# be used as a standalone app as well.
# USAGE: Make it executeable and run with -h to get usage flags.
# You will also probably want to set up a cron task to make it run as a
# sort of fake service.
# SETTINGS:
TEMPDIR="/tmp"
SCRIPTNAME=${0##*/}
