Usage: busybox [function [arguments]...]

   or: busybox --list

   or: function [arguments]...

	BusyBox is a multi-call binary that combines many common Unix

	utilities into a single executable.  Most people will create a

	link to busybox for each function they wish to use and BusyBox

	will act like whatever it was invoked as.
