       "This class calculates an average depth for a queue, based on a "
       "smoothing weight and a sampling time interval. The latter are "
       "properties of this Service, describing how it operates and its "
       "necessary parameters. The Service does the calculation on "

          "This property is a 32-bit unsigned integer, ranging between "
          "0 and 100,000 - specified in thousandths. It defines the "
          "weighting of past history in affecting the calculation of "
          "the current average queue depth. The current queue depth "
          "calculation uses the inverse of this value as its factor, "
          "and one minus that inverse as the factor for the historical "
          "average. The calculation takes the form: \n"
          "average = (old_average*(1-inverse of SmoothingWeight)) \n"
          "+ (current_queue_depth*inverse of SmoothingWeight) \n"
