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 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 example:

        compare_text($file1, $file2)

    is basically equivalent to

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

RETURN
    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.
