Class Method Details
.add_cats(entry, collection, authent, reporter = nil) ⇒ Object
Decorate an entry which is about to be posted to a collection with some
categories. For each fixed categories element, pick one of the categories
and add that. If there are no categories elements at all, or if there's
at least one with fixed="no", also add a syntho-cat that we make up.
Return the list of categories that we added.
