+	/// @brief Wrapper for PortAudio error codes to C++ exceptions.
+	///
+	/// It wraps up PortAudio's error handling mechanism using 
+	/// C++ exceptions and is derived from std::exception for 
+	/// easy exception handling and to ease integration with 
+	/// other code.
+	///
+	/// To know what exceptions each function may throw, look up 
+	/// the errors that can occur in the PortAudio documentation 
+	/// for the equivalent functions.
+	///
+	/// Some functions are likely to throw an exception (such as 
+	/// Stream::open(), etc) and these should always be called in 
+	/// try{} catch{} blocks and the thrown exceptions should be 
+	/// handled properly (ie. the application shouldn't just abort, 
+	/// but merely display a warning dialog to the user or something).
+	/// However nearly all functions in PortAudioCpp are capable 
+	/// of throwing exceptions. When a function like Stream::isStopped() 
+	/// throws an exception, it's such an exceptional state that it's 
+	/// not likely that it can be recovered. PaExceptions such as these 
+	/// can ``safely'' be left to be handled by some outer catch-all-like 
+	/// mechanism for unrecoverable errors.
