+@section RTEMS FTP Daemon
+
+The RTEMS FTPD is a complete file transfer protocol (FTP) daemon
+which can store, retrieve, and manipulate files on the local 
+filesystem.  In addition, the RTEMS FTPD provides ``hooks'' 
+which are actions performed on received data.  Hooks are useful
+in situations where a destination file is not necessarily
+appropriate or in cases when a formal device driver has not yet
+been implemented.
+
+@subsection Configuration Parameters
+
+The configuration structure for FTPD is as follows:
+
+@example
+struct rtems_ftpd_configuration
+@{
+   rtems_task_priority     priority;           /* FTPD task priority  */
+   unsigned long           max_hook_filesize;  /* Maximum buffersize  */
+                                               /*    for hooks        */
+   int                     port;               /* Well-known port     */
+   struct rtems_ftpd_hook  *hooks;             /* List of hooks       */
+@};
+@end example
+
+The FTPD task priority is specified with @code{priority}.  Because
+hooks are not saved as files, the received data is placed in an
+allocated buffer.  @code{max_hook_filesize} specifies the maximum
+size of this buffer.  Finally, @code{hooks} is a pointer to the 
+configured hooks structure.
+
+@subsection Initializing FTPD (Starting the daemon)
+
+Starting FTPD is done with a call to @code{rtems_initialize_ftpd()}.
+The configuration structure must be provided in the application 
+source code.  Example hooks structure and configuration structure
+folllow.
+
+@example
+struct rtems_ftpd_hook ftp_hooks[] =
+   @{
+      @{"untar", Untar_FromMemory@},
+      @{NULL, NULL@}
+   @};
+
+struct rtems_ftpd_configuration rtems_ftpd_configuration =
+   @{
+      40,                     /* FTPD task priority */
+      512*1024,               /* Maximum hook 'file' size */
+      0,                      /* Use default port */
+      ftp_hooks               /* Local ftp hooks */
+   @};
+@end example
+
+Specifying 0 for the well-known port causes FTPD to use the
+UNIX standard FTPD port (21).
+
+@subsection Using Hooks
+
+In the example above, one hook was installed.  The hook causes
+FTPD to call the function @code{Untar_FromMemory} when the 
+user sends data to the file @code{untar}.  The prototype for
+the @code{untar} hook (and hooks, in general) is:
+
+@example
+   int Untar_FromMemory(unsigned char *tar_buf, unsigned long size);
+@end example
+
+An example FTP transcript which exercises this hook is:
+
+@example
