Defining global objects using YUI Doc

Question

How to define a global variable using YUI Doc. I can't find suitable comment tag to define a global object and its properties. What is the best way to do it. Below is my defined object:

var glob = glob || {
    breakPoints: {
        mainNavigation: 840
    },
    animation: {
        speed: {
            slow: 1000
        }
    }
};
