I've added "Zidrav v3.5 Step By Step Guide" to
http://sourceforge.net/docman/?group_id=50757
So here's a page for the utility known as Zidrav. I've pretty much given up on maintaining it. This page is for people who might want to keep it alive. If you want to be added as a developer, or take over completely, just let me know. Otherwise, here it is - the most recent versions.
