#		
#
#	REVISION HISTORY:
#
#		1-JUN-1986	XXX
#		Rewrite for vers 2.0 ...
#		I broke out uucpsetup into three subprograms which
#		live in /usr/lib/uucp.  The subprograms are:
#
#			1) addmodems - 
#			   Configure dialers for use with uucp and tip.
#
#			2) addoutsys -
#			   Add systems to call out to.
#
#			3) addinsys -
#			   Add systems allowed to call us.
#
#		The one-time setup stuff is still done here directly.
#		This includes making default spool directories, adding
#		cron entries for uucp.* scripts, and insuring default
#		USERFILE entries.  The rest just frontends the new
#		programs in /usr/lib/uucp. 
#
#		16-Feb-1988 lea  /usr/lib/uucp -> /usr/var/uucp
#		11-Aug-1989 lea  Change crontab entries for uucp.week
#			and longhall, they were setup to execute once
#			a month and not once a week
#
