Google Code Search has indexed Subversion and Mercurial repositories, so people can search open source projects. How can I do the same for my company's repository with the least effort and without publishing our code?
We have Trac (with Subversion) at our shop, but it only indexes Changesets, and we also have Visual Source Safe.
A quick Google turned up VoilaSVN but I cannot vouch for it.
Edit: It also turned up OpenGrok which appears to have a lot more support for other systems.
