c2man
     
         An automatic {documentation} extraction tool by Graham
        Stoney .  c2man extracts comments
        from {C} source code to generate functional interface
        documentation in the same format as sections 2 and 3 of the
        {Unix} Programmer's Manual.  It looks for comments near the
        objects they document, rather than imposing a rigid {syntax}
        or requiring the programmer to use a typesetting language.
        Acceptable documentation can often be generated from existing
        code with no modifications.
     
        c2man supports both {K&R} and {ISO}/{ANSI C} coding styles.
        Output can be in {nroff} -man, {Texinfo} or {LaTeX} format.
        It {automagically} documents {enum} parameter and return
        values, it handles both {C} (/* */) and {C++} (//) style
        comments, but not C++ grammar (yet).  It requires {yacc},
        {byacc} or {bison} for syntax analysis; {lex} or {flex} for
        {lexical analysis} and {nroff}, {groff}, {texinfo} or {LaTeX}
        to format the output.  It runs under {Unix}, {OS/2} and
        {MS-DOS}.
