My bad, I see that there *IS* a comment at the start of this page
indicating that the documentation is old.  Unfortunately, I entered
the middle of this via search and started editing when I saw there
was outdated information and didn't see the note at the top.

I'll try to submit a patch.

Cheers, Andreas
