# Purpose:	Set up /etc/svc.conf
# Usage:	svcsetup
# Environment:	Bourne shell script
# 
# Remarks:
#    Sets up files:
#	/etc/svc.conf
#
# Modification History:
#
# 11-Dec-89	sue
#	Added silent client mode specifically for dms.  Allows a
#	diskless manager to give a client a default svc.conf file of
#	either "local", "local,yp", or "local,bind" for all databases.
#
# 24-Jul-89	logcher
#	Created.
