Creating periodic cron jobs

[Robert Fitzpatrick]

I am trying to create a quarter-daily cron job on my FreeBSD 5.2.1 as
follows in /etc/crontab:

05 0,6,12,18     *     *     *     root  periodic quarter-daily

I created the /etc/periodic/quarter-daily directory and placed my script
there. After I ran 'crontab -u root /etc/crontab', now I am getting
these mail messages below, it seems I have created, for example, cron
jobs as 'root /usr/libexec/atrun' in addition to the usual
'/usr/libexec/atrun'. It has done this for daily, weekly, etc. as well.
Can someone tell me what I did wrong?
