0006 # Do the equivalent of the 'makedepend' program, but do it right.
0007 #
0008 # Usage:
0009 #
0010 # makedepend [cpp-flags] [-w width] [-s magic-string] [-f makefile]
0011 # [-o object-suffix]
0012 #
0013 # Notes:
0014 #
0015 # The C compiler used can be overridden with the environment
0016 # variable "CC".
0017 #
0018 # The "-v" switch of the "makedepend" program is not supported.
0019 #
0020 #
0021 # This script should
0022 # work on both USG and BSD systems. However, when System V.4 comes out,
0023 # USG users will probably have to change "silent" to "-s" instead of
0024 # "-" (at least, that is what the documentation implies).
