;;; Commentary:
;; Enable WakaTime for the current buffer by invoking
;; `wakatime-mode'. If you wish to activate it globally, use
;; `global-wakatime-mode'.
;; Set variable `wakatime-api-key' to your API key. Point
;; `wakatime-cli-path' to the absolute path of the CLI script
;; (wakatime-cli.py).
