We already have such a section, don't we? (not that I'd want to
discourage doc additions!).

We already make what I thought were some obvious references, but no
matter.  What's the problem with such references?  (I don't think we
really need such stuff to be free per GNU docs, because it isn't
actually program doc.)

I think ftnchek (Toolpack?) will do that if it helps.
