SuSE 7.1/manual for cron

Hi, Does anybody know where I can find a manual for the configuration of cron. Last year it was easy with SuSE 6.4 and crontab but know I have to play with /etc/cron-daily etc and (am I stupid) I find nowhere a manual for the configuration of cron-daily (I mean in which script do I have to enter my own instruction?). In /etc/aaa_base there is a line that says that local changes must be added to cron.daily.local but where is cron.daily.local?)
