This made Python 2's print behave like Python 3's print().

In some cases, where we had:

   from __future__ import print_function
   """Intended module documentation..."""

this will have the side effect of making the intended module documentation
work as the actual module documentation (i.e. becoming __doc__), because
it is once again the first statement in the module.

traffic_replay: Assign users to groups by default 2019-04-30T23:18:28+00:00 Tim Beale timbeale@catalyst.net.nz 2019-04-10T00:55:26+00:00 641d74cb267e87a22df8f9a3d285e3ab4343ce50 The traffic_replay script has a myriad of options, but by default when it creates user accounts it does not assign these users to any groups (you have to specify extra options to do that).

When the window is short compared to the traffic replay time and the true expected conversation length, this has a significant distorting effect, leading to more conversations than would be expected to generate a given number of packets. To offset this slightly we add the --conversation-persistence option which tries to convert apparent death into a longish wait.
