> The toybox build produces a multicall binary, a "swiss-army-knife" program
that acts differently depending on the name it was called by (cp, mv, cat...).
Installing toybox adds symlinks for each command name to the $PATH.

With no arguments, it lists available commands. This allows you to use toybox
without installing it, and is the only command that can have an arbitrary
suffix (hence "toybox-armv5l").
