      Cscope is a developer's tool for browsing source code.  It has
      an impeccable Unix pedigree, having been originally developed at
      Bell Labs back in the days of the PDP-11.  Cscope was part of
      the official AT&T Unix distribution for many years, and has been
      used to manage projects involving 20 million lines of code!
