Since the unofficial wiki seems to have disappeared, the documentation
of the "Jack and Loopback device as Alsa-to-Jack bridge" has gone with
it. Neither google cache nor the wayback machine fare able to serve a
copy of the page. There are plenty of references to the wiki page on
the web, but no-one seems to have mirrored the page. Does anyone
happen to have a copy of the documentation lying around?

Not a copy of the whole article, but the essentials - here using zita-aj
instead of for alsa_in/out
