	help
	Some BusyBox applets have more configuration options than anyone
	will ever care about.  To avoid drowining people in complexity, most
	of the applet features that can be set to a sane default value are
	hidden, unless you hit the above switch.
	This is better than to telling people to edit the busybox source
	code, but not by much.
	See http://en.wikipedia.org/wiki/Fibber_McGee_and_Molly#The_Closet
