What is '<%%' in ERB in Rails?
<p>I have bean seen code of scaffold in rails. I found </p>

<pre><code>&lt;%% breadcrumb_add "&lt;%= plural_table_name.capitalize %&gt;", &lt;%= plural_table_name %&gt;_path %&gt;
&lt;%%= render 'form' %&gt;
</code></pre>

<p>What is <strong><code>&lt;%%</code></strong>  and how to use?</p>
