//// Description /////////////////////////////////////////////////////////////
//																			//
//	The engine is where parsing and execution of console commands takes		//
//	place. It takes place independently of the interface, so that the		//
//	execution can happen from an INI file, from a screen-based console or	//
//	even a GUI interface.													//
