GNU cflow - Summary
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.
