Scripts to generate representative network traffic and replay this to a
samba instance.  For load testing, performance profiling and capacity
planning.

traffic_learner  process a file generated by traffic_summary and
                 generate a model that can be used by traffic_replay to
                 generate samba network traffic.

traffic_replay   Replay a summary file generated by traffic_summary, or
                 use a model created by traffic_learner to generate
