41// Short overview over the debug output macros:
42//	PRINT()
43//		is for general messages that very unlikely should appear in a release build
44//	FATAL()
45//		this is for fatal messages, when something has really gone wrong
46//	INFORM()
47//		general information, as disk size, etc.
48//	REPORT_ERROR(status_t)
49//		prints out error information
50//	RETURN_ERROR(status_t)
51//		calls REPORT_ERROR() and return the value
52//	D()
53//		the statements in D() are only included if DEBUG is defined
