# The devel/cflow port

## cflow-1.4 – analyze C source files and print a call graph

## Description

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

    GNU cflow 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.

    Note: this program is written in C and is not the same as cflow-2.x
    which is a bash script using a lex and yacc generated parser.
