* See https://groupes.renater.fr/wiki/txm-info/public/specs_commande_exporter link to the spec...

For the user, this command could be equivalent to RCP "Export binary corpus" (but the corpora will be pre-built)

To precise in the spec:
* what corpus to download (binary web or binary RCP)
* what to do if only a part of the corpus is free of copyright restrictions (e.g. bfm)
* permissions and logs for this command
