Interfacing Erlang with the Outer World
=======================================

Native Libraries

There are plenty of different approaches on integrating NIFs written in other
languages:

Ports and Network
-----------------

For the situations when you still need the speed and can tolerate some call
latency over, but don't want to risk crashing your node: choose interaction over
network or a port.
