I was just checking to make sure you were awake ;-)

I took the chapter from the printed version I had in front of me, but forgot 
that it is off by one in comparison to the online version.  Doh!

I don't think that stuff exists at all =(O|  Ian Lance Taylor wrote the stuff 
for the Goat book, but it is something about which I have no clue.  If the 
licensing doesn't bother you (along with the fact we may publish a 2nd 
edition at some point), you could take Ian's chapter as a starting point, and 
add the stuff you think is missing.  You could then put the result up on the 
web separately, or else contribute it back to the book.  The book *is* open 
source after all -- and this is exactly why I wanted it that way.  The 
license is at the end of the book.

Cheers,
        Gary.
