longDescription = ''
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.
