function jQuery() {
      // empty constructor function
}

jQuery.fn = jQuery.prototype;  // Make a "fn" property that simply references the 
                               //    jQuery.prototype object.

// So assigning a property to jQuery.fn 
//    is the same as assigning it to jQuery.prototype
jQuery.fn.sayHello = function() { alert( "Hi!" ); };

// Create an object from the jQuery constructor
var obj = new jQuery;

// Our new object will automatically inherit the "sayHello" function
obj.sayHello();  // "Hi!"


jQuery.fn.sayGoodbye = function() { alert("Goodbye!"); };

// call the new method on our original object
obj.sayGoodbye();  // Goodbye!
