12 # Contrary to the nagios concept, this script takes
13 # a file, not a hostname as an argument and returns
14 # the status of hosts and services described in that
15 # file. Use these hosts.cfg entries as an example

22 # Notes:
23 # - you need the lmstat utility which comes with flexlm.
24 # - set the correct path in the variable $lmstat.
