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