[CentOS] Anyone using trac on centos?

(Besides Paul, who's busy?)

I just need one question answered: I keep reading the docs, and given the
old traditional
/var/www
I get that part of trac should be installed in /var/www/trac/<myproj> (I
think); what I can't figure out is whether there is *anything* under the
document root, that is, /var/www/html/trac/<myproject>.

Anyone have a clue? Do I even need it as a placeholder, or does anything
actually go in there?
