+# 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##*/}
