 CVS :        $Id: test1.c,v 1.2 2003-01-07 17:10:17 pj Exp $

 File:        $File$
 Revision:    $Revision: 1.2 $
 Last update: $Date: 2003-01-07 17:10:17 $
 ------------

 this test shows a set of 5 tasks (+main+dummy+keyboard driver).
 
 The first 4 tasks are scheduled by a EDFSTAR Module, whereas the
 fifth one is a standard traditional EDF task. The 4 tasks uses a
 budget of 10000/100000.
 
 if edfstar.c is compiled with edfstar_printf3 active, a couple
 (dline, curtime) is showed (in ms).
 
 if cbsstar.c is compiled with cbsstar_printf3 active, the budget
 replenishments are showed.
