DragonflyBSD architecture handbook?

[Noah Yan]

Where I can find the architecture handbook for dragonflybsd? I cannot find 
it from google and wiki.

I was trying to compile the architecture book from the source code tree and 
stopped these days since I am busy on Pittsburgh for SC04.

Anybody from dragonflybsd team is working on it? I would be happy to 
contribute and I am digging into FreeBSD architecture book.
