[maemo-users] where is crontab ?

[From: Olivier Ricou]

Hi,

I'm a newbie who just spent his week-end configuring his new N800 (I
don't like keyboard for handhelds). I tried to configure some
updates but couldn't find crontab. I've seen that the package
debianutils has a cron but it seems you should not install it if
you don't want to destroy everything. I could not find any other
package with cron and since no one complains on the web, I presume
it must be something simple, but what ?

Can someone explain me how to set up a crontab ?

TIA,

Olivier.
