This software is part of the GNU Project.

GNU cflow analyzes a collection of C source files and prints a graph charting control flow within the program.

Current implementation 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).

Input files can optionally be preprocessed before analyzing.

The package also provides Emacs major mode for examining the produced flowcharts in Emacs.
