<p>Mario,</p>
<p>My initial draft got one pass through DAI, which generated many
good comments that I've tried to accommodate. But the attachment
is the first anyone has seen this version, so any missteps are
purely my own.</p>
<p>In general, the meat seems to be in charts 4-7. The rest are
added information that might be useful in a tutorial setting. <br>
