+Removes "unwanted" HTML tags from incoming messages and unescapes html.
+
+Some XMPP clients like Adium or Pidgin send HTML tags like <font>, <b>, <u>, etc
+to format text, specially when using OTR. This plugin removes them and also
+unescapes HTML like &lt;, &gt;, etc that these clients also tend to escape.
