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