Methods for the adventurous

  "Net::FTP" inherits from "Net::Cmd" so methods defined in "Net::Cmd" may
  be used to send commands to the remote FTP server.

  quot (CMD [,ARGS])
      Send a command, that Net::FTP does not directly support, to the
      remote server and wait for a response.

WARNING This call should only be used on commands that do not
require data connections. Misuse of this method can hang the
connection.
