This is a simple Mesos-DNS client written in Python.

Use it as CLI tool like so:

$ ./mc.py localhost redis.marathon.mesos
$ Discovered redis.marathon.mesos running on 10.141.141.10:31000

Alternatively you can import mc in your Python app and use lookup_service(mesosdns_server, service_name) which will yield an (ip, port) tuple for the logical service_name.
