# usage: check_saned pattern

# This script will run "scanimage -L" and grep for the supplied pattern.
#
# FIXME: since scanners in use are not included in the list produced
# by "scanimage -L", the state should be OK if the scanner was seen
# within the last hour, and WARNING if it was seen within the last
# day.
#
# This check script is maintained in a Subversion repository at
