*
*	   Grotwin - provides a somewhat primitive windowing capability
*	for people unfortunate enough to use the standard 24 x 80 type
*	of terminal when the console is in use.  Definitely written for
*	4.[2,3] at the present time, as Sys V.2 does not cater for pseudo
*	terminals or have the select() facility (amongst other things !)
*	(version 8 should fix this).
*
*	Files used :-
*
*	   grotwin.c	 -	window system initialisation
*				deals with startup files
*
*	   manager.c	 -	window manager
*				deals with input and output
*
*	   window.c	 -	window manipulator
*				deals with aspects concerning windows
*				during normal usage
*
*	   update.c	 -	simulates dumb terminal for use
*				with window manager.
*
*	   grotwin.h	 -	header file for above
*
*	   utmp.c	 -	utmp manipulator
*				updates utmp entries for each window
*
*	   grotwin.make  -	makefile for above
*	   
*	Bugs :-
*
*	   Can't have the situation where no windows are present !
*	   Needs a vt100 like terminal type
