The upgrade to the latest copy from subversion wasn't clean. I've
gone through two different site upgrades so far, and both had the same
results.

1 - When you click on a 'random book' you get the top of the book tree.
2 - Even though books had previously been classified in categories and
supcategory, the index only shows them in categories.
3 - In the administration section, find the correct book to update and
repair is very difficult.

Bottomline, it appears incomplete and unfinished.
