     M\bMk\bkd\bde\bep\bp 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 _\bd_\be_\bp_\be_\bn_\bd__\bf_\bi_\bl_\be, or ._\bd_\be_\bp_\be_\bn_\bd by default.  An
     example of its use in a Makefile might be:

           CFLAGS= -O -DDEBUG -I../include -I.
           SRCS= file1.c file2.c

           depend:
                mkdep ${CFLAGS} ${SRCS}

     where the macro SRCS is the list of C source files and the macro CFLAGS
     is the list of flags for the C compiler.

     Options:

     -\b-p\bp    m\bmk\bkd\bde\bep\bp produces dependencies of the form ``program: program.c'' so
           that subsequent makes will produce _\bp_\br_\bo_\bg_\br_\ba_\bm directly from its C
           module rather than using an intermediate ._\bo module.        This is useful
           in directories that contain many programs, each of whose source is
           contained in a single C module.

     -\b-a\ba    Append to the output file, so that multiple m\bmk\bkd\bde\bep\bp's may be run from
           a single Makefile.
