#	remote OCF RA. This script provides metadata for the internal
#	pacemaker remote lrmd connection agent.  Outside of acting
#	as a place holder so the remote ra script can be indexed and
#	providing metadata, this script should never be invoked.  The
#	actual functionality behind the remote lrmd connection lives
#	within pacemaker's crmd component.
