A tutorial?  What's the URL?  I can't find it.

Just a warning to Em Huynh that the esql logicsheet is very powerful
but it requires a basic understanding of JDBC and a very good
understanding of XSL.  Then, you have to understand the Cocoon
processors and tag libraries.  I've been looking through it for longer
than I care to admit.  It gradually makes sense.

Start with something simple.  Maybe, mail.xml and it's stylesheet or
this tutorial if Donald will post the URL.

If you try to start with esql, expect it to take some time to understand.
Print it out (paper is good these days during Silicon Valley blackouts),
and if you get frustrated, you can step on it.  Actually, Donald, I
haven't stepped on it...yet.  I just have an unusual sense of humor.
I hope nobody minds.
