       src2man - extract man pages from source files.

       src2man [-n][-d date][-v volume][-r release] [srcfile ...]

       src2man scans source file srcfile. Only C source files are supported
       for now. Comments blocks starting by "/** num", where num is a section
       number, are converted into a man file, using txt2man(1).

       The first line of the comment block must contain the name of the
       manpage, usually the function name, followed by a "-" and a short
       description. The following lines are the "DESCRIPTION" section content,
       except if they are in upper case, in which case they define a new

       If the next line after a comment block is empty, Then no "SYNOPSIS"
       section will be generated. Otherwise, src2man will look in the
       following source lines for a function prototype or a type definion
       (struct, union, typedef, ...) matching the manpage name, and include it
       in a "SYNOPSIS" section. This avoids to duplicate the type or function
       prototype in the comment block.

       The best place for code documentation is in the source file, where the
       body is implemented, not the header file which only contains the
       prototype. src2man automatically searches for the presence of a
       prototype in the corresponding header file, and if found, will print a
       "#include" statement in the synopsis.

       -d date
              Set the date of the man pages. Defaults to current date.

       -n     No man page is created. The name of the manpages that would be
              created are printed.

       -v volume
              Specify the name of the volume to be printed in center header of
              generated manpages.

       -r release
              Specify the project name and release number for the generated

              Unix timestamp that is used for date in header instead of
              current date.

       The following example displays C code and comments to generate a
       manpage foobar.3:

            /** 3
             * foobar - a sample dummy function
             * This line is now the first of the description section.
             * Note that function parameters parm1 and parm2 are highlighted
             * in the generated man page.
            int foobar(char *parm1, int parm2)
               return 0;
