+<h3><a name="posinclass">Locating commodities in the YPP client UI</a></h3>
+
+In the Voyage Trading Plan, YARRG indicates after the commodity name
+where in the YPP commodity UI each commodity can be found. First
+comes the initial letter of the category:
+% my $dbh= dbw_connect('Midnight');
+% my $getclasses= $dbh->prepare(
+% "SELECT commodclass FROM commodclasses ORDER BY commodclass");
+% $getclasses->execute();
+<%
+ join '; ', map { $_->[0] =~ m/^./ or die; "<strong>$&</strong>$'" }
+ @{ $getclasses->fetchall_arrayref() }
+%>.
+<p>
+Then, if applicable, follows one of the following indications:
+<% join ', ', map { "<strong>$_</strong>" } qw(tt t m b bb) %>
+indicating whether the commodity is in the top, 2nd, middle,
+2nd-to-last or bottom fifth of the list of commodities of the same
+class, respectively.
+<p>
+For example,
+<blockquote>
+<table><tr>
+<td>Fine pink cloth
+<td><div class=mouseover
+ title="Fine pink cloth is under Cloth, commodity 14 of 55">C t</div>
+</table>
+</blockquote>
+indicates that Fine pink cloth can be found under Cloth,
+between 20% and 40% of the way down through the types of Cloth.
+If you mouseover that in a suitably equipped browser you should see the
+text:
+<blockquote>
+Fine pink cloth is under Cloth, commodity 14 of 55
+</blockquote>
+<p>
+
+The position indicator (tt, t, etc.) isn't shown for very small
+categories.
+
+The exact location of the commodity in the actual game
+client may vary because YARRG only considers the list of all possible
+commodities, not the list of actual offers at the island in question.
+
+Also, not all commodities are always completely categorised or
+ordered; we are working to add the additional data
+
