 * I was using this...but it's bad (not accurate)....
 
	// browser detect - returns the users browsers language preference
	function browsLang() {
		return ( navigator.language || navigator.userLanguage );
	};
 
 * 
 * Thanks to DanSingerman @ javascript for detecting browser language preference - Stack Overflow http://bit.ly/czTmtO
 * This requires jQuery, but gives a more accurate read of the user's browser language pref
 * by reading the http header from the user's browser upon request to :  http://ajaxhttpheaders.appspot.com/
 *

var browserLang;
 
jQuery.ajax({
	url: "http://ajaxhttpheaders.appspot.com",
	dataType: 'jsonp',
	success: function(headers) {
		browserLang = normaliseLang(headers['Accept-Language']);
		carryOnFriend();
	}
});
 
 
// The following function contains the real meat of the script file
// But because I'm in a hurry, I'll wrap most of my file inside this function
// Then we'll run this fn as a callback when everything else if finished
 
function carryOnFriend() {
 
	// Everything else that needs to happen after the AJAX goes here
 
	jQuery(document).ready(function($) {
		// Stuff to do as soon as the DOM is ready. Use $() w/o colliding with other libs;
	});
