+<code class="Nm">rf</code> is a reference system for troff and other roff
+  derivatives. It differs from <a class="Xr">refer(1)</a>, the traditional troff
+  reference system, in a couple important ways:
+<ol class="Bl-enum">
+  <li>References are not stored in a separate file. They are defined via macros
+      in the troff document itself.
+    <p class="Pp">This means that you can move, copy and share your troff
+        document without needing to worry about an additional reference file.
+        Furthermore, you never run the risk of accidentally losing the
+        references attached to a document.</p>
+  </li>
+  <li><code class="Nm">rf</code> is around 150 lines of Perl. If you find a bug
+      or an (in your opinion) undesirable behavior in
+      <code class="Nm">rf</code>, you can easily patch it.</li>
+  <li>Finally, <code class="Nm">rf</code> is much more simple and offers much
+      more basic functionality than <a class="Xr">refer(1)</a>. This means that
+      you can learn all of it in five minutes.</li>

+<code class="Nm">rf</code> is controlled by several macros, all consisting of
+  one uppercase and one lowercase letter, beginning with either an
+  &#x2018;F&#x2019; (format macros) or an &#x2018;R&#x2019; (inline reference
+  and reference list macros). These are listed below in alphabetical order.

+In a format definition, use a percent (%) sigil followed by a single letter to
+  interpolate any given field of the reference. The letter following the percent
+  sign corresponds to the second letter of the reference list macros described
+  above. For example:
+<div class="Bd Pp Bd-indent">
+<pre>
+.Ff (%a, %y)      \&quot; (Author, Year)
+</pre>
+</div>
+<p class="Pp">By wrapping an interpolation in braces, you can specify a prefix
+    and/or suffix that should be included only if the interpolation is
+    successful. For example:</p>
+<div class="Bd Pp Bd-indent">
+<pre>
+.Ff (%a{, %y}).   \&quot; Here, ', ' is removed if there is no year.
+</pre>
+</div>
+<p class="Pp">Note that all fields are inserted literally, except
+    <i class="Em">%a</i>, from which the forenames of the authors are
+  removed.</p>
+<p class="Pp">Finally, you usually don't need to worry about excessive spaces
+    and stray punctuation marks, as <code class="Nm">rf</code> removes many of
+    these these automatically.</p>
