busybox is a "do everything" application that's used a lot in rescue
disks and those mini-distros (I used to use a 486 running LRP as my
router - it booted off a floppy and the machine had no hard disk or CD
ROM in it). It looks at its argv to see how it was invoked to see
what it's supposed to do. The idea is that instead of having a bunch
of applications, dynamic libraries and a dynamic loader, you have one
statically linked application so you don't have the overhead of
dynamic loading but you also only need one copy of the libraries.
Unfortunately a lot of the busybox versions of these applications are
really stripped down to minimal functionality.

servile, but is morally treasonable to the American public." -- Teddy Roosevelt
