case BAUM_RSP_RoutingKey: // singular
  resetKeyGroup(packet.data.values.routingKeys, cellCount,
                packet.data.values.routingKey);
    goto doRoutingKeys; // plural

This code converts a single-key function into a key-group function. This 
technique is simply a quick way of implementing the single-key functions as 
their corresponding key-group functions so that they can be most easily 
handled.
