Term::ShellUI uses the history and autocompletion features of Term::ReadLine to
present a sophisticated command-line interface to the user. It tries to make
every feature that one would expect to see in a fully interactive shell trivial
$to implement. You simply declare your command set and let ShellUI take care
of the heavy lifting.

This module was previously called Term::GDBUI.
