jQuery Plugin Check Version
<p>When writing a new jQuery plugin is there a straightforward way of checking that the current version of jQuery is above a certain number? Displaying a warning or logging an error otherwise.</p>

<p>It would be nice to do something like:</p>

<pre><code>jQuery.version &gt;= 1.2.6
</code></pre>

<p>in some form or another.</p>
