[Zope] Client.py

[Bak @ kedai]

hi all
has anybody successfully used Client.py that ships with Zope-2.2.0?  i can't 
seem to run it.  even on the command line.  i've searched the mailing list, 
but to no avail

this is what i did:
python Client.py http://www.zope.org

and here's the traceback.  
Traceback (innermost last):
  File "Client.py", line 639, in ?
    main()
  File "Client.py", line 632, in main
    headers, body = apply(f,(),kw)
  File "Client.py", line 221, in __call__
    raise NotAvailable, RemoteException(
bci.NotAvailable: argument 1: expected read-only character buffer, tuple 
found (File: http://www.zope.org Line:
[])
None None for None   

what did i do wrong?  can i use Client.py from Zope-2.1.x?
