I had been of the opinion that *all* package-specific documentation
(whether setup/usage instructions or "FAQs"), should go in the
respective README file under /usr/doc.

However, I now realise this is a silly position to take, and I'll start
adding information about problems like this to the FAQ.  I'll probably
create a whole new section about logging in.

If nobody objects, that is.

Cheers,
David
