SYNOPSIS ^

    #
    #    create ringbuffer
        #
        use Devel::RingBuffer;
        use Devel::RingBuffer::TieInt;

        my $ringbuf = Devel::RingBuffer->new(
                File => 'somefile.trace',
                Rings => 20,
                Slots => 20,
                MessageSize => 256,
                GlobalSize => 24 * 1024,
                StopOnCreate => 0,
                TraceOnCreate => 1) || die "Can't create a ring buffer.";

        my $ring = $ringbuf->allocate();
        #
        #       setup the next slot in the ring
        #
        $depth = $ring->nextSlot();
        #
        #       update the current slot with the new linenumber and timestamp
        #
        $ring->updateSlot();
        #
