+If the \fB-p\fP option is provided, \fImkdep\fP produces dependencies
+of the form ``program: program.c'' so that subsequent makes will
+produce \fIprogram\fP directly from its C module rather than using an
+intermediate \fI.o\fP module.  This is useful in directories that
+contain many programs, each of whose source is contained in a single
+C module.
