[Pietro Terna]

        Hi All,

        some minor observations about tutorial application.

1. We just
had a tutorial-1.0.1 version before the last one; what the differences?

2.
In my opinion, one difference is the elimination of the simpleExperBug
example (effectively, trying to compile it against 1.0.4, I've obtained a
lot of warning messages).

3. The present tutorial-1.0.1, like the previous
one, contains an error in bug.m within simpleObserverBug and
simpleObserverBug2 (see the following lines, where the commented one is
wrong):

-drawSelfOn: (Raster *) r {
// [r drawPointX: xPos Y: yPos Color:
3];
  [r drawPointX: xPos Y: yPos Color: 2];
  return self;

        Yours, Pietro
