Can anybody tell me how MooX::Cmd is supposed to work?

The MANIFEST can, probably, lets see

MooX::Cmd -> http://search.cpan.org/dist/MooX-Cmd/MANIFEST
t/01-simple.t
t/lib/FirstTestApp.pm...

If you know what @ARGV is and read MooX::Cmd you can see that "myapp.pl command command" is supposed to call sub execute in module MyApp::Cmd::Command::Cmd::Command

myapp.pl would be  use MyApp; MyApp->new_with_cmd;

But if you try it out, you'll see that it only calls sub MyApp::execute

http://deps.cpantesters.org/depended-on-by.pl?dist=MooX-Cmd-0.002 shows an example duckpan which has  App::DuckPAN->new_with_cmd; and App::DuckPAN::Cmd

sub execute {
    my ( $self, $args, $chain ) = @_;
    my $app = shift @{$chain};
    $self->app($app);
    $self->run(@{$args});
}

but its completely different.

So sorry, I don't know how MooX::Cmd is supposed to work, and neither does its documentation
