    This script copies a PureData project to the BeagleBone and runs it 
    using libpd. The Bela-libpd executable should have first been copied
    to the $BBB_LIBPD_EXECUTABLE_PATH folder on the Beaglebone.
    The source directory should contain a file called _main.pd, which is the 
    patch that will be loaded into Pd. All the content of the folder is 
    recursively copied and the folder structure is flattened.
    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.
	
    The -f argument runs the project in the foreground of the current terminal,
    within a screen session that can be detached later with ctrl-A ctrl-D.
    The -F argument runs the project in the foreground of the current terminal,
    without screen, so	the output can be piped to another destination."
