+.Nm mkdep
+.Nd construct Makefile dependency list
+.Sh SYNOPSIS
+.Nm mkdep
+.Op Fl ap
+.Op Fl f Ar file
+.Op Ar flags
+.Ar file Op Ar ...
+.Sh DESCRIPTION
+.Nm mkdep
+takes a set of flags for the C compiler and a list
+of C source files as arguments and constructs a set of include
+file dependencies which are written into the file ``.depend''.
+An example of its use in a Makefile might be:
+.Bd -literal -offset indent
+CFLAGS= -O -I../include
+SRCS= file1.c file2.c
+
+depend:
+	mkdep ${CFLAGS} ${SRCS}
+.Ed
+.Pp
+where the macro SRCS is the list of C source files and the macro
+CFLAGS is the list of flags for the C compiler.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl a
+Append to the output file,
+so that multiple
+.Nm mkdep Ns 's
+may be run from a single Makefile.
+.It Fl f Ar file
+Write the include file dependencies to 
+.Ar file ,
+instead of the default ``.depend''.
+.It Fl p
+Cause
+.Nm mkdep
+to produce dependencies of the form:
+.Bd -literal -offset indent
+program: program.c
+.Ed
+.Pp
+so that subsequent makes will produce
+.Ar program
+directly from its C module rather than using an intermediate
+.Pa \&.o
+module.
+This is useful for programs whose source is contained in a single
+module.
