tool to at least achieve much of what people might be using traffic_shell for. What’s missing
is the “config” portion, where traffic_shell implements basically the equivalent of calling
traffic_line -s -v.

to be a kitchen sink :)

Yep. My preference would be to have at least two sinks; traffic_line as it has been for a
long time is exclusively to talk to the mgmt port, whereas other tools (including traffic_shell)
have been a hodge lodge. So, maybe a traffic_tool? I also feel that it’d be better with
a Perl (or Python, or Go) than a C/C++ program for the kitchen sink of admin tools, since
most such tools would be written by people with little or no C++ skills (and I wouldn’t
expect them to).

Ok. The reason I wrote the perl script is because there were rumblings last time we tried
to remove traffic_shell.
