This class provides an FTP client which is substantially extended beyond the basic Sun FTP URL support. It supports auto login with password. It also allows the creation of FtpFile - a filesystem independent fake filesystem.

This code is based on the Ftp.java file by Joseph Szabo: jszabo@remus.rutgers.edu
