erlang shell implementation question

[Mariano Guerra]

Hi,

 I'm trying to improve the implementation of efene's[0] shell. Right
now it doesn't have readline-like capabilities, that is, the ability
to edit the line before evaluating it, or having a history of previous
commands.

I was reading the shell.erl file and I couldn't find the place where
the input is read and the features described above (plus shortcuts
like ctrl+a) are implemented.

can someone point me to the file and function where this is implemented?

thanks!
