<P>This wheel follows the end of an ever-growing file, perhaps a log
file, and generates events whenever new data appears. It is a
read-only wheel, so it does not include a <CODE>put()</CODE> method. It uses
<A HREF="../../../../lib/Pod/perlfunc.html#item_tell"><CODE>tell()</CODE></A> and <A HREF="../../../../lib/Pod/perlfunc.html#item_seek"><CODE>seek()</CODE></A> functions, so it's only suitable for plain files.
