Re: Configuring DatabaseReader? (suggestion for documentation)

[Jonathan Layes <j....@layes.com>]

Perfect, thanks Gerhard!  "use-connection" is a child of reader, not
an attribute of reader as I incorrectly guessed. 

Pascal's email should be incorporated in the documentation - it makes
a fine mini-tutorial.  There really is a lot of useful database stuff
in that post.  Are any of the docs people listening?  :)  

Cheers, Jonathan
