How would I hook Trac up to multiple repositories?
In this case I don't want to use the ticketing system or the wiki, simply connect it to browse multiple repos.
I would think it would be as easy as having a script update the repository link in its conf.ini file every time you wanted to look at a new repo, right?
There's been much talk about doing this but currently it's unsupported by Trac.
You would need to make multiple instances of Trac, one for each repository. You can't just change the configuration file as Trac stores a bunch of information about the repository in its database and doing that would break it.
