This class creates the ROOT Application Environment that interfaces to the windowing system eventloop and eventhandlers.

This class must be instantiated exactly once in any given application. Normally the specific application class inherits from TApplication (see TRint).

TApplication::TApplication	(	const char *	appClassName,
		Int_t *	argc,
		char **	argv,
		void *	options = `0`,
		Int_t	numOptions = `0`
	)

Create an application environment.

The application environment provides an interface to the graphics system and eventloop (be it X, Windows, MacOS or BeOS). After creating the application object start the eventloop by calling its Run() method. The command line options recognized by TApplication are described in the GetOptions() method. The recognized options are removed from the argument array. The original list of argument options can be retrieved via the Argc() and Argv() methods. The appClassName "proofserv" is reserved for the PROOF system. The "options" and "numOptions" arguments are not used, except if you want to by-pass the argv processing by GetOptions() in which case you should specify numOptions<0. All options will still be available via the Argv() method for later use.
