annotate scripts/run_pd_libpd.sh @ 470:5a936f8e9447 prerelease

I mean it actually works for real. Libpd checks for file and exits with meaningful error message if it does not find it.

	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 copying the files.
	
	The -c option passes command-line arguments to the Bela program; 
	enclose the argument string in quotes.
	
	The -b argument runs the projet in the background, so that no output is displayed
	in the terminal.
	The -f argument runs the project in the foreground of the current terminal,
	without screen, so the output can be piped to another destination."
