Chris@39: 	/// @brief A RAII idiom class to ensure automatic clean-up when an exception is 
Chris@39: 	/// raised.
Chris@39: 	///
Chris@39: 	/// A simple helper class which uses the 'Resource Acquisition is Initialization' 
Chris@39: 	/// idiom (RAII). Use this class to initialize/terminate the System rather than 
Chris@39: 	/// using System directly. AutoSystem must be created on stack and must be valid 
Chris@39: 	/// throughout the time you wish to use PortAudioCpp. Your 'main' function might be 
Chris@39: 	/// a good place for it.
Chris@39: 	///
Chris@39: 	/// To avoid having to type portaudio::System::instance().xyz() all the time, it's usually 
Chris@39: 	/// a good idea to make a reference to the System which can be accessed directly.
Chris@39: 	/// @verbatim
Chris@39: 	/// portaudio::AutoSys autoSys;
Chris@39: 	/// portaudio::System &sys = portaudio::System::instance();
