[erlang-questions] Writing my own REPL

[Attila Babo]

This minimal wrapper starts a custom shell as you requested and ^G
works nicely. With Robert's hacked user_drv it's more convenient to
start multiple copies of your own shell. With rlwrap it's pretty
usable. :-)

Is this what are you guys after?

Cheers:
Attila
