OpenGrok is a nice source code browser that has powerful searching built in. It is, as its web site says, wicked fast (or as we say here in northern California, hella fast). I set it up on my web server, indexing FreeBSD's cvs repository. I don't have ports in there just yet, because OpenGrok is crashing when trying to parse some files in the ports tree. Hopefully I'll get that sorted out soon. Update: ports are in there now.
Clicky here to try it out.
