This page has not been written yet. I did, however, finish the page about setting up a subversion repo with trac, which runs under Apache and mod_python.
Running your repositories under Apache can actually be a better idea, even if you don't set up trac, because it allows you to use SSL, and because most firewalls will allow ports 80 and 443 to go through, but may not allow port 3690 (which is used by the native svn protocol.)
If you're already familiar with daemontools and just need a "run" script which is known to work, service-svn-run is available.
