It then removes packages starting with 'quirks' (a required package on OpenBSD) and determines how many remain. If there are no packages, return 0, otherwise, echo the package names and return 2. Returning 0 or 2 is significant because crontab(5) with the -n switch determines whether to send mail. Since we are likely to run this nightly, we do not want to flood our inbox with output from cron when there is no action to take.
