This is a mirror of GNU cflow git repository.

GNU cflow analyzes a collection of C source files and prints a graph charting control flow within the program.

It 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. The package also provides Emacs major mode for examining the produced flowcharts in Emacs.

See its home page and Savannah page for more information. The latter is mirrored on this server.
