BusyBox v1.18.3 (2012-12-03 15:06:10 CST) multi-call binary.

Usage: busybox [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.
