Igor,
Thank you for pointing this section out to me. The information there is
useful, but I would comment for John Dover's interest that the section
was hard to find. I'd been on that page several times before, but
became overwhelmed by the time I got that far down. Maybe the 'What do
I have' section should be at the top and the 'What can I do with it'
section should come second? (My personal opinion, of course).
It is certainly a challenge with a software project this vast to figure
out how to organize the documentation so that it's easy for the
unfamiliar to find what they need.
