-- Retrieves a fleet\'s runtime configuration settings. The runtime
-- configuration tells GameLift which server processes to run (and how) on
-- each instance in the fleet.
--
-- To get the runtime configuration that is currently in forces for a
-- fleet, provide the fleet ID.
--
-- If successful, a @RuntimeConfiguration@ object is returned for the
-- requested fleet. If the requested fleet has been deleted, the result set
-- is empty.
