Live info
---------

This is a tool that shows CPU, memory, I/O, network and battery
information on an always-visible layer, updated once a second.
Uses system-reserved OMAP hardware layer, so should be visible
in most programs that don't use tv-out (tv-out needs that same
layer to send video to TV).

When you want to exit Live info, just run this pnd again.
