What use are these (rpm) entries in 'man'?

OK, maybe, but it would be *much* more useful if one was pointed at
some information about the thing in question, e.g. 'man -k yelp' tells
me:-

    yelp                (rpm) - A system documentation reader from the Gnome project

but doesn't give me a clue as to how to find out anything else.  The
whole point of 'man -k' or 'apropos' is surely to point at the place
where you can find out more about they keyword you have entered.
