I find these kinds of comments are by far the most useful, but they're
hard to find because the commenter must be somewhat altruistic.
They usually don't have anything to gain by making what might be
perceived as negative comments.

Here, I think, the comments were driven by a genuine desire to see
POV-Ray users learn and improve.
