Instead, we might want to build localized .mdwn files +for the basewiki, and then ikiwiki would just use that translated underlay. +The when the user edits index, they get a nice mdwn file to start from. + +So, we seem to have two cases, in one po files from the underlay should be +used, in the other not.
