Entry point for jquery document
<p>In every JQuery tutorial the entry point is always like this:</p>

<pre><code>$(document).ready(function() {
   ...
});
</code></pre>

<p>But in <a href="https://github.com/voloko/sdoc" rel="nofollow">sdoc</a> project it has different entry point as for my novice's view.
Here's the code snippet and <a href="https://github.com/voloko/sdoc/blob/master/lib/sdoc/generator/template/direct/resources/panel/index.html" rel="nofollow">there</a> the full file:</p>

<pre><code>&lt;script type="text/javascript" charset="utf-8"&gt;
    //&lt;![CDATA[
    function placeholder() {
        ...
    }
    $(function() {
       placeholder();
       ...
    })
    //]]&gt;
&lt;/script&gt;
</code></pre>

<p>The question: Is <code>$(function()..)</code> the entry point for jquery script? And if it does why it differ from traditional approach? Thanks</p>
