### Protocol Implementation
# This is just about the simplest possible protocol
class Echo(Protocol):
def dataReceived(self, data):
"As soon as any data is received, write it back."
self.transport.write(data)
### Persistent Application Builder
# This builds a .tap file
if __name__ == '__main__':
# Since this is persistent, it's important to get the module naming right
# (If we just used Echo, then it would be __main__.Echo when it attempted
# to unpickle)
