package VCP::UI ;

=head1 NAME

VCP::UI - User interface framework for interactive mode VCP.

=head1 SYNOPSIS

    $ vcp

=head1 DESCRIPTION

When VCP is run with no source or destination specifications, it loads
and launches an interactive user interface.

The current default is a text user interface, but this may change
to be a graphical UI on some platforms in the future.
