I really want to buy this, just to have a
nice printed set of module documentation
that I can hold in my hands and read
anywhere. Not that it would be light
reading, but what I have in mind is
browsing. The price is not a problem,
it looks well worth it.

But... why doesn't O'Reilly do an update?
A lot has happened in two years. It was a
great disappointment to learn that the only
version available is the first edition.
