twisted.conch example

[Dag]

I'm trying to write a program that uses twisted.conch ssh client 
connection.  However I cannot really get twitsed.conch working and
the documnetation for it is lacking.

Does anyone have any sample code which shows twisted logging onto an
ssh server (using a supplied password), executing a command and getting
the output of the command?  I'm sure if I could just see that basics 
working I can figure out the rest.
