7 # 22-May-1996: remove the use of the "-a" flag for /bin/sh because it is not
8 # implemented in the FreeBSD shell. Sigh.

10 # 12-Mar-1997: add s/#.*$// to the sed script to allow for comments on the
11 # ends of settings - someone got caught.
12
13 # 18-Apr-1997: put the tab character into a variable to stop it getting
14 # lost by accident (which has happened a couple of times).
15
16 # 19-Jan-1998: indented settings in the makefile weren't being handled
17 # correctly; added [$st]* before \\([A-Z] in the pattern, to ignore leading
18 # space. Oddly, the pattern previously read ^\([A-Z which didn't seem to
19 # cause a problem (but did when the new bit was put in).

23 # BEWARE: tab characters needed in the following sed command. They have had
24 # a nasty tendency to get lost in the past, causing a problem if a tab has
25 # actually been present in makefile. Use a variable to hold a space and a
26 # tab to keep the tab in one place. This makes the sed option horrendous to
27 # read, but the whole script is safer.
