  42 /*  FUNCTION
  43         Informs the workbench application that an object has changed, and that
  44         it should update it's visual representation.
  45
  46     INPUTS
  47         name - Name of object that has changed.
  48         type - Type of object (WBDISK, WBTOOL, ...).
  49         tags - Additional options.
  50
  51     TAGS
  52         No tags are defined at this time.
  53
  54     NOTES
  55         This function is TEMPORARY! It will hopefully go away before AROS 1.0,
  56         and it might change it's API several times before that!

  60     BUGS
  61         The existance of this function is a bug itself. It should be removed
  62         once there is a adequate notification API in dos.library that works.
