  2.     CD³²Ctrl - controlls several features of your CD³² games console
  3.  
  4.     this is just an AmigaDOS frontend for the lowlevel.library function
  5.     SystemControl(). written by Daniel Balster
  6.  
  7.     example usage:
  8.     
  9.     CD32CTRL NOREQ NOCDREBOOT ; no more requesters & cdeject-resets
  10.     CD32CTRL REQ CDREBOOT     ; the opposite...
  11.  
  12.     do not offer both (i.e. REQ NOREQ) i won't check that.
  13.  
  14.     (not much comments in it - forgive me)
