Ruby library for cron and at

I have to build an application that will drive other processes which
will have to be started at given times. Some of these will have to
be started periodically, but most only once. This will take place
on a Linux machine, so ‘cron’ and ‘at’ will be probably be the weapons
of choice.

Now, I want to handle these from ruby, and I found ‘Ruby Cron’ to
interface with cron. I have not found anything that gives me a
convenient interface to ‘at’ (searching for such a library turned
out to be a challenge).

So my questions: Does there exist a ruby library that provides
an interface to ‘at’? Is Ruby Cron the right choice to interface
with cron?

Thanks,

Michael

rufs-scheduler ( http://openwferu.rubyforge.org/scheduler.html ) behaves
like both ‘cron’ and ‘at’.
