NAME

       src2man - extract man pages from source files.

SYNOPSIS

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

DESCRIPTION

       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 section.

       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.

OPTIONS

       -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 manpage.

EXAMPLE

       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;
            }
