| /** |
| * Basic FTP client. Performs the following actions: |
| * <ul> |
| * <li> <strong>send</strong> - send files to a remote server. This is the |
| * default action.</li> |
| * <li> <strong>get</strong> - retrieve files from a remote server.</li> |
| * <li> <strong>del</strong> - delete files from a remote server.</li> |
| * <li> <strong>list</strong> - create a file listing.</li> |
| * <li> <strong>chmod</strong> - change unix file permissions.</li> |
| * <li> <strong>rmdir</strong> - remove directories, if empty, from a |
| * remote server.</li> |
| * </ul> |
| * <strong>Note:</strong> Some FTP servers - notably the Solaris server - seem |
| * to hold data ports open after a "retr" operation, allowing them to timeout |
| * instead of shutting them down cleanly. This happens in active or passive |
| * mode, and the ports will remain open even after ending the FTP session. FTP |
| * "send" operations seem to close ports immediately. This behavior may cause |
| * problems on some systems when downloading large sets of files. |
