# @(#)doconfig	4.4	(ULTRIX)	2/28/91
#
# 009 - Jan, 1991 - Jon Wallace
#	Removed the zic command from this script because of incompati-
#	bility with the date command, and of the process used in this
#	script.
#
#	Changed date example to reflect the current year.
#
# 008 - Aug, 1990 - Jon Wallace
#	Put in functionality to allow bind hostnames as the system
#	name.
#
# 007 - Feb, 1990 - Jon Wallace
#		Fixed Time problem by repositioning zic command.
#		Restructured time zone entry by asking user for
#		time *east* of Greenwich.
#
# 006 - May, 1989 - Jon Wallace
#		Added zic(8) support.
#
# 005 - Mar, 1989 - Jon Wallace
#		Changed hierarchy of directories for merged pool.
#		Merged VAX and MIPS doconfig scripts into one.
#
# 004 - Dec, 1988 - Jon Wallace
#		* Added user interface for disk placement of swap, dump,
#			etc, during interactive use on Pmax.
#		* Added Console_type subroutine to remove UWS opition
#			from config file, if machine is not worksystem.
#
# 003 - May, 1987  - Donnie Cherng
#		* Added the environment for the diskless.
#		- p : If the root path is not /, give a full path root.
#		- c : for a specific config file.
#		- e : a edit script for the new config file.
#
# 002 - Mar, 1987  - Tungning Cherng
#		* Added the flag for installation use.
#		-i : doconfig -i [sysname] [timezone day light saving area}
#		-n : set for the sysname.
#		-t : set for the date and time
#		* Fix the time for the Non-EST USA area.
#
# 001 - June, 1986 - Tung-Ning Cherng
#		* Added the advanced installation flag.
#		* system name can be mixed with upper and lower case.
#		* Timezone for the area may be a negative number.
#
#	Edited prompts on Aug. 5, 1986 by Al Wojtas
#
# 000 - May, 1986 - Bob Fontaine
#		Revised for V2.0 installation from V1.2
