-//@DESCRIPTION: This component provides a single class, 'bdlm::Metric', that is
-// a variant of metric values.
+//@DESCRIPTION: This component defines a value semantic class, 'bdlmt::Metric',
+// that represents a measurement (or measurements) for a metric.
+// A 'bdlm::Metric' value is collected from an object that reports metrics
+// using a callback that is registered with the 'bdlm::MetricsRegistry'.  A
+// 'bdlm::Metric' value is a variant type, which can hold one of several types
+// of measurements (in theory).  Currently the only supported metric type is a
+// 'Guage', which represents a single instantaneous value for the most recent
+// measurement.
