+Many years ago Matt's evil twin, Friar Puck, released a "pucked"
+version of MIT/GNU Scheme, advertising that it was available at a
+couple URLs:
+</p>
+
+<ul class="org-ul">
+<li><code>git://birchwood-abbey.net/~puck/mit-scheme.git</code></li>
+<li><code>https://birchwood-abbey.net/~puck/Scheme/</code></li>
+</ul>
+
+<p>
+These are actually duplicates of the "resources" at these URLs:
+</p>
+
+<ul class="org-ul">
+<li><code>git://birchwood-abbey.net/~matt/mit-scheme.git</code></li>
+<li><code>https://birchwood-abbey.net/~matt/Scheme/</code></li>
+</ul>
+
+<p>
+So the abbey's Google Indexing report warned of the duplicates, and
+explained that they would not be indexed. To get them off the report,
+the following redirects make clear that the canonical source is
+Matt's.
+</p>
+
+<div class="org-src-container">
+<code>apache-pucked</code><pre class="src src-conf" id="org217bddf"><code>RedirectMatch /~puck$ /~matt
+RedirectMatch /~puck/(.*) /~matt/$1
+</code></pre>
+</div>
+
+<p>
+The seemingly duplicated Git repository at <code>/~puck/mit-scheme.git</code> is
+actually the symbolic link at <q>/home/puck/Public</q> targeting
+<q>/home/matt/Public</q>.
