Tool to chart control flow within the C program

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.
