;;; Usage
;; Use `deftest' to define a test and `run-elk-test' to run it.
;; Create test bundles with `defsuite' or `build-suite'.
;; Verify your code with `assert-equal', `assert-eq', `assert-eql',
;; `assert-nonnil', `assert-t', `assert-nil' and `assert-error'
;; to verify your code.
;; Enable window-numbering-mode and use M-1 through M-0 to navigate.
;;
;; If you want to affect the numbers, use window-numbering-before-hook or
;; window-numbering-assign-func.
;; For instance, to always assign the calculator window the number 9, add the
;; following to your .emacs:
;;
;; (setq window-numbering-assign-func
;; (lambda () (when (equal (buffer-name) "*Calculator*") 9)))
;;; Version 0.9
