That's what I was trying to point you to. In scm you can say something like:
        (if (dump "new-executable")
                (display "\"new-executable\" successfully made\n")
                (exit 0))) of the program...

It wouldn't be too hard to pull the code out of scm and add it to the
ocaml library. But it would rewuire some C coding experience.
