 		The stored data can be saved to or parsed from a file, though ConfigFile objects can also be used directly without accessing the filesystem.
-		The following example shows how to parse an INI-style file from the system, read its contents and store new values in it:

-		if err == OK: # If not, something went wrong with the file loading
-		    # Look for the display/width pair, and default to 1024 if missing
-		    var screen_width = config.get_value("display", "width", 1024)
-		    # Store a variable if and only if it hasn't been defined yet
-		    if not config.has_section_key("audio", "mute"):
-		        config.set_value("audio", "mute", false)
-		    # Save the changes by overwriting the previous file
