manta looks like it's parsing an envelope type manually instead of
defining a proto definition for it. next step is to try to synthesize
that definition based on the manta code. it appears to be as follows:
message Envelope {
required EDemoCommands command = 1;
required varint tick = 2;
required varint size = 3;
required bytes body = 4;
}
or something to that effect. Reading protobuf primitives off the wire
manually is looney-bins.
