-<p>Template statements are based on <a href="#template-expr">template exressions</a> and provide the full equivalent of <a href="http://en.wikipedia.org/wiki/JavaServer_Pages">JSP</a> but in a general way.  Template statements write the equivalent template exression to standard output.  For example:</p>

-<p><tt><pre><%=Html.encode[[
-	local name = "Bob"

-	Hello <%=name%>!

-	<%
-]]%></pre></tt></p>

-<h4 margin-top="1em"><a name="template-expr">Template Expressions</a></h4>
-
-<p>Luan adds a new type of expression based on <a href="http://en.wikipedia.org/wiki/JavaServer_Pages">JSP</a> called template expressions.  Template expressions return multiple values.  Here is an example:</p>
-
-<p><tt><pre><%=Html.encode[[
-	local name = "Bob"
-	write( %>Hello <%=name%>!<% )
-]]%></pre></tt></p>
+<h4 margin-top="1em"><a name="template_expr">Template Expressions</a></h4>
 
-<p>This is equivalent to the code:</p>
-
-<p><tt><pre>
-	local name = "Bob"
-	write( "Hello ", name, "!" )
-</pre></tt></p>
-
-<p>The strings in template expressions may be multiple lines.</p>
