+This is a simple implementation of multicast DNS query support for an Arduino
+running on ESP32 chip. 

+Usage:
+- Include the ESP32 Multicast DNS library in the sketch.
+- Call the begin method in the sketch's setup and provide a domain name (without
+  the '.local' suffix, i.e. just provide 'foo' to resolve 'foo.local'), and the
+  Adafruit CC3000 class instance.  Optionally provide a time to live (in seconds)
+  for the DNS record--the default is 1 hour.
+- Call the update method in each iteration of the sketch's loop function.
