OpenGrok

I came to see one of my colleague using a source code browser today which is called as OpenGrok. A very good source code browser and its straight away catch my eye because of the name, i see an 'Open'. I did some research behind this app and found some thing interesting, the application is built using java, yes it is, worth take a look back at the source code. Another important thing to note is that this tool can very well exist with most of the source control systems. It use apache Lucen indexing and so on. Lot many exciting features. I'm thinking of installing this in my group as well
