+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).
