SYNOPSIS

       ifnames [OPTION] ...  [FILE] ...


DESCRIPTION

       Scan  all of the C source FILES (or the standard input, if
       none are given) and write to the standard output a  sorted
       list  of all the identifiers that appear in those files in
       `#if', `#elif', `#ifdef', or `#ifndef' directives.   Print
       each  identifier  on a line, followed by a space-separated
       list of the files in which that identifier occurs.

       -h, --help
              print this help, then exit

       -V, --version
              print version number, then exit
