=head1 NAME

    VCP::UIMachines - State machines for user interface

=head1 SYNOPSIS

    Called by VCP::UI

=head1 DESCRIPTION

The user interface module L<VCP::UI|VCP::UI> is a framework that bolts
the implementation of the user interface to a state machine representing
the user interface.

Each state in this state machine is a method that runs the state and
returns a result (or dies to exit the program).

=cut

use strict;

use VCP::Debug qw( :debug );
use VCP::Utils qw( empty );

=head1 API

=over

=item new

Creates a new user interface object.

=cut

sub new {
    my $class = ref $_[0] ? ref shift : shift;
    my $self = bless { @_ }, $class;
}

=item run

Executes the user interface.

=cut

sub run {
    my $self = shift;
