autotest bindings

I should add that I keep the previous autotest code in autotest.el and the following in my setup-modes.el (I have my emacs setup broken up):

(autoload 'autotest-switch "autotest" "doco" t)
(autoload 'autotest "autotest" "doco" t)
(add-hook 'ruby-mode-hook
          '(lambda ()
             (define-key ruby-mode-map (kbd "C-c C-a") 'autotest-switch))

This allows me to use C-c C-a to toggle back and forth between autotest and ruby files. I should also have it hooked in for grep buffers and other things, but I'll leave that as an exercise for the reader. :P
