NAME

PerlIO::reverse - Reads lines backward

SYNOPSIS

        open my $rev, '<:reverse', 'foo.txt';
        print while <$rev>; # print contents reversely

The :reverse layer reads lines backward like tac(1).

Here is a minimal implementation of tac(1).

        #!/usr/bin/perl -w
        # Usage: $0 files...
        use open IN => ':reverse';
        print while <>;
        __END__

This layer cannot deal with unseekable filehandles and layers: tty, :gzip, :dir, etc.
This layer is partly incompatible with Win32 system. You have to call binmode($fh) before pushing it dynamically.
