Thanks - I've been out of town and just now am able to respond to this. 
 In addition to Hal's nice Ruby/Tk work, I had help from David Alan 
Black; he contributed the program organization chapters (where 
inheritance, modules, and some very thoughtful ideas about abstraction 
and generalization are discussed).  The book lists Hal and David as 
contributors in the frontmatter but doesn't specify what they provided.

Corrections of misprints and such will shortly be listed on a webpage; 
y'all will be the first to know about that.
