	The interactive texconfig utility will be started now. Make sure
	your screen has at least 24 rows and 80 columns. If texconfig
	crashes now, you can still set up your teTeX system using the
	batch mode of texconfig.  Try 'texconfig help' to get a list
	of options.

	The interactive mode works best with a real vt100 terminal or
	inside an xterm window.
