   They're in /var/cron/tabs.  If you're using individual crontab files,
   be sure to rename /etc/crontab or you might have duplicated cronjobs
   running simultaneously.

   I use the file header beneath my signature for crontab files, so I
   don't forget what field goes where.  It's also handy to define an
   environment variable in case a program should behave differently when
   run under cron.
