    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.
	
    The -f argument runs the project in the foreground of the current terminal,
    within a screen session that can be detached later. The -F argument runs
	the project in the foreground of the current terminal, without screen, so
	the output can be piped to another destination."
