+      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!
