How can I determine the direction of a jQuery scroll event?

Question

I\'m looking for something to this effect:

$(window).scroll(function(event){
   if (/* magic code*/ ){
       // upscroll code
   } else {
      // downscrol

This is simple and easy detection for when the user scrolls away from the top of the page and for when they return to the top.

$(window).scroll(function() {
    if($(window).scrollTop() > 0) {
        // User has scrolled
    } else {
        // User at top of page
    }
});
