XCOMM $XConsortium: mdepend.cpp,v 1.7 91/08/22 11:42:53 rws Exp $
|
||||
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).
