IEx.CLI

Function start/0

In order to work properly, IEx needs to be set as the proper -user when starting the Erlang VM and we do so by pointing exactly to this function.

If possible, Elixir will start a tty (smart terminal) which makes all control commands available in tty available to the developer.

In case tty is not available (for example, Windows), a dumb terminal version is started instead.
