    (description
     "GNU cflow analyzes C source files and produces a graph charting the
control flow of the program.  It can output the graph in several styles and
in either the POSIX format or in an extended GNU format. cflow also includes
a major mode for Emacs for examining the flowcharts that it produces.")
