/// <reference path="jquery-1.3.2-vsdoc2.js"/>
// The above reference gives jQuery intellisense with Visual Studio.
// You must also:
// 1. Install VS 2008 SP1.
// 2. Install VS 2008 Patch KB958502 to Support "-vsdoc.js" Intellisense Files:
//    http://code.msdn.microsoft.com/KB958502/Release/ProjectReleases.aspx?ReleaseId=1736
// 4. Download the jQuery-vsdoc.js file
//    Save the jquery-vsdoc.js file next to your jquery.js file in your project.
// Note: Intellisense for $ will not work inside this construct:
//       function($) { })(jQuery); - Typical for plugins. The reason is here: 
//       http://docs.jquery.com/Using_jQuery_with_Other_Libraries
//       As a work around can use jQuery instead of $ and you get full intellisense.
