# ldirectord OCF RA. Wrapper around /usr/sbin/ldirectord to
# be OCF RA compliant and therefore to get the possibility
# to monitor ldirectord by HAv2.
# Tested on SuSE Linux Enterprise Server 10.
#
# Should conform to the specification found at
# http://www.linux-ha.org/OCFResourceAgent
# and
# http://www.opencf.org/cgi-bin/viewcvs.cgi/specs/ra/resource-agent-api.txt?rev=HEAD
#
# ToDo: Add parameter to start several instances of ldirectord
# with different config files.
