Charts control flow within source code.

'GNU cflow' analyzes a collection of C source files and prints a graph charting control flow within the program. It can produce both direct and inverted flowgraphs for C sources, or optionally generate a cross-reference listing. It implements either POSIX or GNU (extended) output formats. Input files can optionally be preprocessed before analyzing. The package also provides an Emacs major mode, so users can examine the produced flowcharts in Emacs.
