/**
 * Demonstrates use of the outbound gateway to use ls, get and rm.
 *
 * The previous Test {@link FtpOutboundChannelAdapterSample} was uploading 2 test
 * files:
 *
 * <ul>
 *     <li>a.txt</li>
 *     <li>b.txt</li>
 * </ul>
 *
 * This test will now retrieves those 2 files and removes them. Instead of just
 * polling the file, the files are instead retrieved and deleted using explicit
 * FTP commands (LS and RM)
