4# HISTORY
5#  1-Dec-87  Michael Young (mwyoung) at Carnegie-Mellon University
6#	Added "-verbose" switch, so this script produces no output
7#	in the normal case.
8#
9# 10-Oct-87  Mike Accetta (mja) at Carnegie-Mellon University
10#	Flushed cmu_*.h and spin_locks.h
11#	[ V5.1(XF18) ]
12#
13#  6-Apr-87  Avadis Tevanian (avie) at Carnegie-Mellon University
14#	Use MASTER.local and MASTER.<machine>.local for generation of
15#	configuration files in addition to MASTER and MASTER.<machine>.
16#
17# 25-Mar-87  Mike Accetta (mja) at Carnegie-Mellon University
18#	Removed use of obsolete wb_*.h files when building the feature
19#	list;  modified to save the previous configuration file and
20#	display the differences between it and the new file.
21#	[ V5.1(F8) ]
22#
23# 25-Mar-87  Avadis Tevanian (avie) at Carnegie-Mellon University
24#	If there is no /etc/machine just print out a message telling
25#	user to use the -cpu option.  I thought this script was supposed
26#	to work even without a /etc/machine, but it doesn't... and this
27#	is the easiest way out.
28#
29# 13-Mar-87  Mike Accetta (mja) at Carnegie-Mellon University
30#	Added "romp_fpa.h" file to extra features for the RT.
31#	[ V5.1(F7) ]
32#
33# 11-Mar-87  Mike Accetta (mja) at Carnegie-Mellon University
34#	Updated to maintain the appropriate configuration features file
35#	in the "machine" directory whenever the corresponding
36#	configuration is generated.  This replaces the old mechanism of
37#	storing this directly in the <sys/features.h> file since it was
38#	machine dependent and also precluded building programs for more
39#	than one configuration from the same set of sources.
40#	[ V5.1(F6) ]
41#
42# 21-Feb-87  Mike Accetta (mja) at Carnegie-Mellon University
43#	Fixed to require wired-in cpu type names for only those
44#	machines where the kernel name differs from that provided by
45#	/etc/machine (i.e. IBMRT => ca and SUN => sun3);  updated to
46#	permit configuration descriptions in both machine indepedent
47#	and dependent master configuration files so that attributes can
48#	be grouped accordingly.
49#	[ V5.1(F3) ]
50#
51# 17-Jan-87  Mike Accetta (mja) at Carnegie-Mellon University
52#	Updated to work from any directory at the same level as
53#	"conf"; generate configuration from both MASTER and
54#	MASTER.<machine-type> files; added -cpu switch.
55#	[ V5.1(F1) ]
56#
57# 18-Aug-86  Mike Accetta (mja) at Carnegie-Mellon University
58#	Added -make switch and changed meaning of -config;  upgraded to
59#	allow multiple attributes per configuration and to define
60#	configurations in terms of these attributes within MASTER.
61#
62# 14-Apr-83  Mike Accetta (mja) at Carnegie-Mellon University
63#	Added -config switch to only run /etc/config without
64#	"make depend" and "make".
