    This script copies a directory of source files to the BeagleBone, compiles
    and runs it. The BeagleRT core files should have first been copied over
    using the setup_board.sh script supplied with BeagleRT.

    The source directory should contain at least one .c, .cpp or .S file.
    If the argument -n is passed, the output will not be run after compiling.
    The argument -b will change the local path on the BeagleBone where the
    BeagleRT files are found. The -c option passes command-line arguments to
    the BeagleRT program; enclose the argument string in quotes."
