-;;; Commentary:
-;; * I want to keep my crontabs under rcs to keep a history of
-;; the file. Editing them with 'crontab -e' is rather
-;; cumbersome. My method is to keep the crontab as a file,
-;; under rcs, and check in the changes with 'C-c C-c' after
-;; editing.
-;;
-;; * The remote systems are expected to share a filesystem.
-;; If they dont, modify crontab-shell or crontab-apply to
-;; suit your needs.
-;;
-;; * You may want to add one of these to your startup:
-;; (add-to-list 'auto-mode-alist '("\\.cron\\(tab\\)?\\'" . crontab-mode))
-;; (add-to-list 'auto-mode-alist '("cron\\(tab\\)?\\." . crontab-mode))
