#  Name:  cl_hb_alias_network
#
#  This script is used to manage all the alias addresses for heartbeat on
#  a particular network.
#  The parameters are:
# 	network name - name of the network
#
#	action - there are 2 basic actions:
#  		add - add the alias addresses to the adapters on this network
#  		delete - remove the alias addresses from this network
#
# Returns:      0 - success
#               2 - bad number of arguments
#               any non-0 return from cl_hb_alias
#
# Environment:  VERBOSE_LOGGING,PATH
