Connecting to Programmer Message?

Can someone explain when you would expect to see the message below? What is connecting to what programmer? I get the impression you would see this message if setting up to either reprogram the Leonardo's Boot Loader perhaps, or if the Leonardo was going to be used as a programmer for another Arduino's Boot Loader. I have no experience with programming Boot Loaders but maybe I somehow got the Leonardo into a programming mode. If so, then maybe I can figure out how to get it out of that mode.
Thanks,
Al
