NAME
     nulm - null STREAMS module

DESCRIPTION
     nulm passes all messages it receives, unchanged, to the next module in
     the Stream.  Messages are passed both upstream and downstream.

     The nulm module is useful for inserting a trace module at the top of a
     lower multiplexed Stream for debugging purposes.
