An application can specify exactly what input represents a request to end an
interactive session.  By default, the example definition above is used.

=head2 handle_exception( $e )

    sub handle_exception {
        my ($app, $e) = @_;

        # Handle the exception represented by object $e...
        $app->my_error_logger( error => $e->error, pid => $e->pid, gid => $e->gid, ... );

        warn "caught error ", $e->error, ", continuing...";
        return;
    }

Error conditions are caught by CLIF and forwarded to this exception handler.
It receives an exception object (see L<Exception::Class::Base> for methods
that can be called on the object).

If not overridden, the default implementation extracts the error message from
