Appending a log file during CU

[John Gayman]

    I have been using the simple command string "cu system | tee log.file"
to log the results from a CU session. Can someone shed some light on 
what string I could use to "append" to a logfile. So that subsequent
"cu system | tee log.file" would keep appending file "log.file" instead
of replacing it each time.  Thanks for any suggestions.
