       File::Compare - Compare files or filehandles

               use File::Compare;

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

       The File::Compare::compare function compares the contents of two sources, each of which can be a file or a file
       handle.  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.

       File::Compare::compare_text does a line by line comparison of the two files. It stops as soon as a difference
       is detected. compare_text() accepts an optional third argument: This must be a CODE reference to a line compar-
       ison function, which returns 0 when both lines are considered equal. For example:

           compare_text($file1, $file2)

       is basically equivalent to

           compare_text($file1, $file2, sub {$_[0] ne $_[1]} )

       File::Compare::compare and its sibling functions return 0 if the files are equal, 1 if the files are unequal,
       or -1 if an error was encountered.

       File::Compare was written by Nick Ing-Simmons.  Its original documentation was written by Chip Salzenberg.
