<h1>A Simple Oriole</h1>
<p>A really simple example:</p>
<p>You can write paragraphs like this.</p>
<pre data-code-language="python" data-executable="true" data-type="programlisting">hey = &quot;hello world&quot;, 38+4
print(hey hello. This is an executable code block )!
</pre>
<div id="the-id">
<p>This is a block inside a div with an id the-id.
Very cool. Yes.</p>
</div>
<pre data-code-language="" >hey = &quot;hello world&quot;, 38+4
print(hey hello. This is a non executable block )!
</pre>
<div id="another-id">
