Associate metatags to submitted e-mail (Nodewords Metatags integration).

Hi.

I don't know how to use commands to parameter some fields of the Meta tags module (also named nodewords).

When we display print_r($node), we see:

[nodewords] => Array
        (
            [description] => A description of the page
            [keywords] => some, keywords
        )

Is it possible to use a command? Something like:

description: bla bla bla
keywords: bla, bla, bla

Thanks.
