 for the negotiated ports use the conversation_set_dissector to define
 the dissection routine.
 
+The second argument to conversation_set_dissector is a dissector handle,
+which is created with a call to create_dissector_handle or
+register_dissector.
+
+create_dissector_handle takes as arguments a pointer to the dissector
+function and a protocol ID as returned by proto_register_protocol;
+register_dissector takes as arguments a string giving a name for the
+dissector, a pointer to the dissector function, and a protocol ID.
+
+The protocol ID is the ID for the protocol dissected by the function. 
+The function will not be called if the protocol has been disabled by the
+user; instead, the data for the protocol will be dissected as raw data.
