                     33: .Nm Mkdep
                     34: takes a set of flags for the C compiler and a list
                     35: of C source files as arguments and constructs a set of include
                     36: file dependencies which are written into the file
                     37: .Ar depend_file  ,
                     38: or
                     39: .Pa \&.depend
                     40: by default.  An example of its use in a Makefile
                     41: might be:

                     44: CFLAGS= -O -DDEBUG -I../include -I.

                     46:

                     50: .Pp
                     51: where the macro SRCS is the list of C source files and the macro
                     52: CFLAGS is the list of flags for the C compiler.

                     57: .Nm mkdep
                     58: produces dependencies of the form
                     59: .Dq Li program: program.c
                     60: so that subsequent makes will produce
                     61: .Ar program
                     62: directly from its C module rather than using an intermediate
                     63: .Pa \&.o
                     64: module.  This is useful in directories that
                     65: contain many programs, each of whose source is contained in a single
                     66: C module.

                     68: Append to the output file,

                     71: may be run from a single Makefile.
