#----
# This script checks for temperature and battery and displays a notification
# (using notify-send) if the limits are too high.
#
# It can either execute a single time, or be run as a daemon (statck -d) that
# will re-run the check each minute.
#
# It has also an option to show the status as a single line (statck -1) which
# can be used for displaying it at applications status line.
