<p>&nbsp;&nbsp;&nbsp; This is an example of GroovyPages showing the use of the editor
visible syntax.&nbsp; This syntax uses curly braces like %&#123; groovlet }% and $&#123;
expression }, instead of the less-than greater-than of JSP, like &lt;% groovlet %&gt;
and &lt;%= expression %&gt;.&nbsp; Though both syntaxes are supported in GroovyPages,
using visible syntax is sometimes preferable when the programmer is also the
page designer or when they want to see and edit their in the web editor's
formatted, normal view, rather than in raw, noisy HTML all of the time.&nbsp;
It's perfectly acceptable to mix both syntaxes on the same page.</p>

<h3>The Source Code</h3>
<p>&nbsp;&nbsp; You will note that the source code below appears more noisy when
compared with JSP syntax.&nbsp; It is when you look at the raw HTML.&nbsp; But
web editors help you to stay out of HTML mode, and when you edit your page that
way most of the noise goes away.</p>
