-;;
-;; * `dired-extra-startup' is part of the `dired-mode-hook'.
-;;
-;; * `dired-extra-startup' calls `dired-hack-local-variables'
-;;
-;; * `dired-hack-local-variables' checks the value of
-;;   `dired-local-variables-file'
-;;
-;; * Check if `dired-local-variables-file' is a non-nil string and is a
-;;   filename found in the directory of the Dired Buffer being created.
-;;
-;; * If `dired-local-variables-file' satisfies the above, then temporarily
-;;   include it in the Dired Buffer at the bottom.
-;;
-;; * Set `enable-local-variables' temporarily to the user variable
-;;   `dired-enable-local-variables' and run `hack-local-variables' on the
-;;   Dired Buffer.
