=head1 SYNOPSIS

    use App::Deps::Verify ();

    App::Deps::Verify->new->verify_deps_in_yamls(
        +{ filenames => [ $opt->{input}, ] } );

    path( $opt->{output} )->spew_utf8("Success!");

Command-line usage:

    shlomif[perl-begin]:$trunk$ deps-app -h
    deps-app <command> [-?h] [long options...]
