// This little code will append a <div> to the body.
// The <div> contains a translatable string "Hello world!"
// You can translate this string easily in the Back office
// of your website by browsing this url : 
// http://you.website.here/admin/build/translate/search
// and search for Hello world!
// PS : it's a case sensitive input
$('<div>'+Drupal.t("Hello world!")+'</div>').appendTo('body');
