This is a valid criticism.  An easy solution is to delete this
small section, but the real problem is that the tutorial doesn't
mention any means of controlling output.  The right solution
would be to have a short introduction to controlling output,
mentioning \paper etc, which would be a suitable vehicle to
introduce the other topics you mention.  Then the example
would flow nicely later.  I'll make a note to look at this.
