title: jQuery Plugin Check Version
body: <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>
