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

    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 -c option passes command-line arguments to
    the Bela program; enclose the argument string in quotes.
	
    -p arg : sets the name of the project to run (default: $BBB_PROJECT_NAME ) 

    By default, the project runs 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. The -b argument runs it
    in a screen in the background, so no output is shown. The -m argument allows
    to pass arguments to the Makefile before the run target. For instance,
    pass -m \`"projectclean"\` or \`-m "distclean"\` to clean project-specific
    pre-built objects, or all the pre-built objects, respectively."
