	Why, there're plenty of tools that support either some sort of a
	standardized output, or output that's user-defined (based on
	some standardized items.)  E. g., the output of ls(1) and
	date(1) is defined by POSIX (IEEE Std 1003.1-2008), etc.

	I believe that there's very little, if any, code duplication
	between e2dis and debugfs.
