-
-This class sets up `cron-apt` so that it downloads upgradable packages, does not
-actually do any upgrade and emails when the output changes.
-
-`cron-apt` defaults to run at 4 AM. You may want to set the
-`$apt_cron_hours` variable before you include the class: its value will
-be passed as the "hours" parameter of a cronjob. Example:
-
-    # Run cron-apt every three hours
-    $apt_cron_hours = '*/3'
-
-Note that the default 4 AM cronjob won't be disabled.
