4 [OpenGrok](https://github.com/OpenGrok/OpenGrok) is a fast and usable source code search and cross reference engine. It helps you search, cross-reference and navigate your source tree. In other words it lets you grok (profoundly understand) source code and is developed in the open, hence the name OpenGrok.
