I ran svnserve under launchd on 10.4 but found that using the built in
Apache2 and svn_dav mod on 10.5 MUCH easier and less finicky. If
anyone in interested in a crudely assembled document about how I did
it, you are more than welcome to visit
<http://steamcode.com/wiki/index.php?title=Turn_on_the_built-in_Subversion_server>.
I want to eventually turn on https access but I am not there yet.
FYI, this is my wiki that I am using to document everything I seem to forget.
