+	/// @brief Class which represents a PortAudio device in the System.
+	///
+	/// A single physical device in the system may have multiple PortAudio 
+	/// Device representations using different HostApi 's though. A Device 
+	/// can be half-duplex or full-duplex. A half-duplex Device can be used 
+	/// to create a half-duplex Stream. A full-duplex Device can be used to 
+	/// create a full-duplex Stream. If supported by the HostApi, two 
+	/// half-duplex Devices can even be used to create a full-duplex Stream.
+	///
+	/// Note that Device objects are very light-weight and can be passed around 
+	/// by-value.
