/** P4Delete - checkout file(s) for delete.
 *
 * Example Usage:<br>
 * &lt;p4delete change="${p4.change}" view="//depot/project/foo.txt" /&gt;<br>
 *
 * Simple re-write of P4Edit changing 'edit' to 'delete'.<br>
 *
 * ToDo: What to do if file is already open in one of our changelists perhaps
 * (See also {@link P4Edit P4Edit})?<br>
