"A wicked fast source browser"

OpenGrok is a fast and usable source code search and cross reference engine. It helps you search, cross-reference and navigate your source tree. It can understand various program file formats and version control histories like Mercurial, Git, SCCS, RCS, CVS, Subversion, Teamware, ClearCase, Perforce and Bazaar. In other words it lets you grok (profoundly understand) the open source, hence the name OpenGrok. It is written in Java.

OpenGrok is the tool used for the OpenSolaris source browser and search.

Story of OpenGrok, Source Code Browser | OSNews | 12/09/2005

OpenGrok in that sense is a true enabler for source code that is open source. It lets people easily and quickly find the source code, look at it, understand the history and changes made to the source. It certainly has made my life easy when I am looking for security holes in software.
