+      GNU cflow analyzes a collection of C source files and prints a
+      graph, charting control flow within the program.
+
+      GNU cflow is able to produce both direct and inverted flowgraphs
+      for C sources.  Optionally a cross-reference listing can be
+      generated.  Two output formats are implemented: POSIX and GNU
+      (extended).
+
+      The package also provides Emacs major mode for examining the
+      produced flowcharts in Emacs.
