+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).
