	/// @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();

	/// @endverbatim
