-XCOMM
-XCOMM Do the equivalent of the 'makedepend' program, but do it right.
-XCOMM
-XCOMM Usage:
-XCOMM
-XCOMM makedepend [cpp-flags] [-w width] [-s magic-string] [-f makefile]
-XCOMM [-o object-suffix]
-XCOMM
-XCOMM Notes:
-XCOMM
-XCOMM The C compiler used can be overridden with the environment
-XCOMM variable "CC".
-XCOMM
-XCOMM The "-v" switch of the "makedepend" program is not supported.
-XCOMM
-XCOMM
-XCOMM This script should
-XCOMM work on both USG and BSD systems. However, when System V.4 comes out,
-XCOMM USG users will probably have to change "silent" to "-s" instead of
-XCOMM "-" (at least, that is what the documentation implies).
