31 GNU cflow analyzes a collection of C source files and prints a
32 graph, charting control flow within the program.
33
34 GNU cflow is able to produce both direct and inverted flowgraphs
35 for C sources. Optionally a cross-reference listing can be
36 generated. Two output formats are implemented: POSIX and GNU
37 (extended).
38
39 The package also provides Emacs major mode for examining the
40 produced flowcharts in Emacs.
