What does /*!*/ mean in C#?
<p>I'm new to C# and am reading code with <code>/*!*/</code> in what seem like strange places.  For instance class methods defined as:</p>

<pre><code>protected override OptionsParser/*!*/ CreateOptionsParser()
protected override void ParseHostOptions(string/*!*/[]/*!*/ args)
</code></pre>

<p>Unfortunately <code>/*!*/</code> is not googleable.  What does it mean?</p>
