28
 this test shows a set of 5 tasks (+main+dummy+keyboard driver).
29
 
30
 The first 4 tasks are scheduled by a EDFSTAR Module, whereas the
31
 fifth one is a standard traditional EDF task. The 4 tasks uses a
32
 budget of 10000/100000.
33
 
34
 if edfstar.c is compiled with edfstar_printf3 active, a couple
35
 (dline, curtime) is showed (in ms).
36
 
37
 if cbsstar.c is compiled with cbsstar_printf3 active, the budget
38
 replenishments are showed.
