     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 comparison function,
     which returns 0 when both lines are considered equal. For

         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.
