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".
