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