+<blockquote>
+<div><ul class="simple">
+<li>Surrounds paragraphs within &lt;p&gt;&lt;/p&gt; (looks for double line breaks to identify paragraphs).</li>
+<li>Single line breaks are converted to &lt;br /&gt;, except those that appear within &lt;pre&gt; tags.</li>
+<li>Block level elements, like &lt;div&gt; tags, are not wrapped within paragraphs, but their contained text is if it contains paragraphs.</li>
+<li>Quotes are converted to correctly facing curly quote entities, except those that appear within tags.</li>
+<li>Apostrophes are converted to curly apostrophe entities.</li>
+<li>Double dashes (either like – this or like–this) are converted to em—dashes.</li>
+<li>Three consecutive periods either preceding or following a word are converted to ellipsis (…).</li>
