Allowing / Denying cron access

[cme]

I know there is a cron.deny file to specify who can't use it, but is there a cron.allow that would alow me to DENY all and allow specific users?

Much like the hosts.[allow,deny]?

What cron do you use?

Vixie, Dillon's,etc.?

I'm not sure about Dillon's, but yes for Vixie.

If the /etc/cron.allow file exists then only users listed in this file are allowed to use cron.

If cron.allow does not exist, but cron.deny does, then everyone NOT listed in cron.deny can use it.
