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, bazaar, SCCS, RCS, CVS, or Subversion. In other words, it lets you grok (profoundly understand) the source. License: Common Development and Distribution License (CDDL) Changes: Lots of bugs have been fixed.
