  {convert,replay}  additional help
    convert         Convert API trace to JSON or Python and back
    replay          Replay messages to running VPP instance

To convert an API trace file to JSON:
vppapitrace convert /tmp/api.trace trace.json

To convert an (edited) JSON file back to API trace for replay:
vppapitrace convert trace.json api-edited.trace

To generate a Python file that can be replayed:
vppapitrace convert /tmp/api.trace trace.py
vppapitrace convert trace.json trace.py

Replay it to a running VPP instance:
vppapitrace replay --socket /tmp/api.trace

In VPP that file can be replayed with:
vpp# api trace replay api-edited.trace

This patch also modifies the API binary trace format, to include the
message id to message name table.
