CruiseControl.Net
CruiseControl.Net is now on SourceForge. Documentation is still a bit lacking, and there are a few problems building it on VS.Net 2003 (oh God, I'm a VS.Net user - now I'll have to take this back...), but at least the source is out there now. I know there are a few people on this site looking at continuous integration and build tools, so I thought I'd give you a heads up. (For those who don't know what Cruise Control or continuous integration is, look here and here).
