Auto-rebooting after power outage with OS X

How do I tell OS X to automatically reboot the machine after a temporary power outage? I seem to remember there was a pretty straightforward way to do this under 9, but I can't find anything under System Preferences, or elsewhere, that would relate to this. Am I missing something really obvious, here? This seems like it should be a basic requirement for any OS that claims to run as a server.
