38 GNU cflow analyzes a collection of C source files and prints a
39 graph, charting control flow within the program.
40
41 GNU cflow is able to produce both direct and inverted flowgraphs
42 for C sources. Optionally a cross-reference listing can be
43 generated. Two output formats are implemented: POSIX and GNU
44 (extended).
45
46 The package also provides Emacs major mode for examining the
47 produced flowcharts in Emacs.
