40# This script is used to dump protobuf packet traces to ASCII
41# format. It assumes that protoc has been executed and already
42# generated the Python package for the packet messages. This can
43# be done manually using:
44# protoc --python_out=. --proto_path=src/proto src/proto/packet.proto
45#
46# The ASCII trace format uses one line per request on the format cmd,
47# addr, size, tick,flags. For example:
48# r,128,64,4000,0
49# w,232123,64,500000,0
41# format.
