+	/// @brief A RAII idiom class to ensure automatic clean-up when an exception is 
+	/// raised.
+	///
+	/// A simple helper class which uses the 'Resource Acquisition is Initialization' 
+	/// idiom (RAII). Use this class to initialize/terminate the System rather than 
+	/// using System directly. AutoSystem must be created on stack and must be valid 
+	/// throughout the time you wish to use PortAudioCpp. Your 'main' function might be 
+	/// a good place for it.
+	///
+	/// To avoid having to type portaudio::System::instance().xyz() all the time, it's usually 
+	/// a good idea to make a reference to the System which can be accessed directly.
+	/// @verbatim
+	/// portaudio::AutoSys autoSys;
+	/// portaudio::System &sys = portaudio::System::instance();
