8 # Do the equivalent of the 'makedepend' program, but do it right.
9 #
10 # Usage:
11 #
12 # makedepend [cpp-flags] [-w width] [-s magic-string] [-f makefile]
13 # [-o object-suffix]
14 #
15 # Notes:
16 #
17 # The C compiler used can be overridden with the environment
18 # variable "CC".
19 #
20 # The "-v" switch of the "makedepend" program is not supported.
21 #
22 #
23 # This script should
24 # work on both USG and BSD systems. However, when System V.4 comes out,
25 # USG users will probably have to change "silent" to "-s" instead of
26 # "-" (at least, that is what the documentation implies).
