+ * This is an example program demonstrating how to use the FTPClient class.
+ * This program connects to an FTP server and retrieves the specified
+ * file. If the -s flag is used, it stores the local file at the FTP server.
+ * Just so you can see what's happening, all reply strings are printed.
+ * If the -b flag is used, a binary transfer is assumed (default is ASCII).
+ * <p>
+ * Usage: ftp [-s] [-b] <hostname> <username> <password> <remote file> <local
file>
