Module          File::Compare   (G/GS/GSAR/perl-5.6.1.tar.gz)

Looks like this module is part of the standare perl 5.6.1
distribution.

NAME
       File::Compare - Compare files or filehandles

SYNOPSIS
               use File::Compare;

               if (compare("file1","file2") == 0) {
                   print "They're equal\n";
               }

DESCRIPTION
       The File::Compare::compare function compares the contents
       of two sources, each of which can be a file or a file han­
       dle.  It is exported from File::Compare by default.

       File::Compare::cmp is a synonym for
       File::Compare::compare.  It is exported from File::Compare
       only by request.
 ....
RETURN
       File::Compare::compare return 0 if the files are equal, 1
       if the files are unequal, or -1 if an error was encoun­
