I haven't had time to take a proper look, test it etc., so I didn't
reply, sorry -- but I am following the thread and I am glad if we have
something to easily/properly support this, so thanks for this.

(And sorry for having triggered all this discussion/work -- at least
if we get this done it will have been worth it :)

I will leave a quick message about the commit message.

Cheers,
Miguel
