Jim, nice work! Here's a couple of item I stumbled across, in the order
I encountered them:

* You might want to explain what 'static method style' is.

* You write: "Log::Log4perl provides easy_init(), which achieves some
  simplification of categories, but you are still faced with creating
  them once" -- but this function doesn't really do anything for categories.
  The stealth logger feature included via 'use Log::Log4perl qw(:easy);'
  is probably what you're referring to -- although you don't have to
  'create' categories, it just uses the class names.

* As mentioned before, I like the coverage feature a lot. What's the
  "unseen log", though, and how does it work?

* Looks like in
        # for example, debug Frob.pm, but only info on Frob::nicate()
        log4perl.category.Frob = DEBUG
        log4perl.category.Frob.nicate.debug = INFO
  -- there's no appender, would be informative to see what the recommended
  way of defining them is (and think of messages "bubbling up" :).

* I didn't understand what you meant by this: "Its probably a bit
  confusing at 1st to have debug=INFO, but this is intentional; it tells
  you the logging level thats coded (so you dont have to go back to the
  source everytime), and therefore what is done if the config-line is
  commented out."

* Question: If a module author decides to ship his module with
  Log::Log4perl::AutoCategorize, will it work if the main program
  (1) doesn't use it?
  (2) uses plain Log::Log4perl?

* As for shipping it with Log::Log4perl ... you're depending on optimizer.pm
  which depends on 5.7.2 -- and Log::Log4perl works with 5.005_03. I
  think you're gonna be better off shipping it as a separate module to
  CPAN, this way you're free in what modules you depend on and don't
  have to support odd configurations (perl 5.005_03, Windows). We'll
  certainly provide a plug for Log::Log4perl::AutoCategorize within the
  Log::Log4perl docs.
