# HISTORY
#  1-Dec-87  Michael Young (mwyoung) at Carnegie-Mellon University
#	Added "-verbose" switch, so this script produces no output
#	in the normal case.
#
# 10-Oct-87  Mike Accetta (mja) at Carnegie-Mellon University
#	Flushed cmu_*.h and spin_locks.h
#	[ V5.1(XF18) ]
#
#  6-Apr-87  Avadis Tevanian (avie) at Carnegie-Mellon University
#	Use MASTER.local and MASTER.<machine>.local for generation of
#	configuration files in addition to MASTER and MASTER.<machine>.
#
# 25-Mar-87  Mike Accetta (mja) at Carnegie-Mellon University
#	Removed use of obsolete wb_*.h files when building the feature
#	list;  modified to save the previous configuration file and
#	display the differences between it and the new file.
#	[ V5.1(F8) ]
#
# 25-Mar-87  Avadis Tevanian (avie) at Carnegie-Mellon University
#	If there is no /etc/machine just print out a message telling
#	user to use the -cpu option.  I thought this script was supposed
#	to work even without a /etc/machine, but it doesn't... and this
#	is the easiest way out.
#
# 13-Mar-87  Mike Accetta (mja) at Carnegie-Mellon University
#	Added "romp_fpa.h" file to extra features for the RT.
#	[ V5.1(F7) ]
#
# 11-Mar-87  Mike Accetta (mja) at Carnegie-Mellon University
#	Updated to maintain the appropriate configuration features file
#	in the "machine" directory whenever the corresponding
#	configuration is generated.  This replaces the old mechanism of
#	storing this directly in the <sys/features.h> file since it was
#	machine dependent and also precluded building programs for more
#	than one configuration from the same set of sources.
#	[ V5.1(F6) ]
#
# 21-Feb-87  Mike Accetta (mja) at Carnegie-Mellon University
#	Fixed to require wired-in cpu type names for only those
#	machines where the kernel name differs from that provided by
#	/etc/machine (i.e. IBMRT => ca and SUN => sun3);  updated to
#	permit configuration descriptions in both machine indepedent
#	and dependent master configuration files so that attributes can
#	be grouped accordingly.
#	[ V5.1(F3) ]
#
# 17-Jan-87  Mike Accetta (mja) at Carnegie-Mellon University
#	Updated to work from any directory at the same level as
#	"conf"; generate configuration from both MASTER and
#	MASTER.<machine-type> files; added -cpu switch.
#	[ V5.1(F1) ]
#
# 18-Aug-86  Mike Accetta (mja) at Carnegie-Mellon University
#	Added -make switch and changed meaning of -config;  upgraded to
#	allow multiple attributes per configuration and to define
#	configurations in terms of these attributes within MASTER.
#
# 14-Apr-83  Mike Accetta (mja) at Carnegie-Mellon University
#	Added -config switch to only run /etc/config without
#	"make depend" and "make".
