Command line in 3.0.1?

I see references in the installation documents to something called
rt_admin. I see a command named ‘rt’ user documentation. I
can’t find either of these things in the source tree. Can someone
point me to it? Is is a separate password. I really, really,
cannot be stuck with nothing but a web interface – it’ll turn me
into a drooling idiot within a week!

Thanks,
