Comunicate Erlang with other process

[Héctor Rivas Gándara]

Hi, 

I need comunicate erlang with an external program. I can add plugins to 
external program, but I can't use it as a driver, it has his own main 
function and it will launch the erlang runtime using exec.

The solution can be code an Erlang driver that will comunicate with the 
external program using IPC or other comunication system.  This driver will 
forward all data from erlang to external process and viceversa. 

I think that this is a common problem, and I  wonder if there is an 
implementation of such driver.
