How to connect to ftp server via proxy using ftplib????

[BruceKL WhoH]

Hi,all
     I am trying to write a simple ftp client, and
I found ftplib module. But my app needs to connect to server
via proxy, I cannot find the way to do this using ftplib .
As we know ,most ftp client app(such as FlashFXP,CuteFtp) can connect to ftp server via proxy.
How to do this?
     Please point me in the right direction. Thanks in advance.
