build_script_usage(){
	echo "	The program can be run in one of the following modes:
		-f arg : runs in the foreground (default).
		-b arg : runs in the background (no output is shown)

	When running in the foreground you can stop the currently running program 
	with ctrl-C.
	When running in the background, you can use \`./stop_running.sh' to stop
	the current process and \`./connect_to_project.sh' to see the program's output.

	Other options:
	--clean : cleans the pre-compiled object files on the board (same as \`-m projectclean').
	          If the linker issues warnings during a build, or you see that your latest changes are not
	          being applied to the running program, try to add the --clean flag for the next build and see 
	          if that fixes it. 
	
	--watch: the script will wait for changes in the source folder and when it detects them it
	         triggers a new build. If you do not run the program with -b, then you will have to
			 either kill the process or detach from the screen in order for the watchdog to be active.
	-n : the output will not be run after compiling.
	-c \"args\" : passes command-line arguments to the Bela program; e
	              close the argument string in quotes.
	-p arg : sets the name of the project to in the remote folder (default: $BBB_PROJECT_NAME ) 
	         do not use spaces in your project names, please
	-m \"args\" 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.
