 SYNOPSIS
-	void flag(string arg)
+        void flag(string arg)
 
 DESCRIPTION
-	Evaluate an argument given as option '-f' to the driver.
-	If several '-f' options are given, this function will be
-	called sequentially with all given arguments.
-	This function can be used to pass the master commands via
-	arguments to the driver. This is useful when building a new
-	mudlib from scratch. It is called only when the system is
-	started.

 EXAMPLE
-	// The code given implements these commands:
-	//  '-fcall <ob> <fun> <arg>': call function <fun> in object <ob> with
-	//				argument <arg>.
-	//  '-fshutdown': shutdown the system immediately.
-	// Thus, starting the driver as
-	//	 'parse "-fcall foo bar Yow!" -fshutdown' would
-	// first do foo->bar("Yow!") and then shut down the system.
