+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.")
