r.js can't replace root.define

[sargismarkosyan]

I use grunt-contrib-requirejs for move all code in one file but r.js wich is using for compilations don't understand following code

root.define(function(require, exports, module){
    root.define.amd.grapnel = true;
    return Grapnel;
});

and can't replace it into something like this

root.define('Grapnel',[],function(require, exports, module){
    root.define.amd.grapnel = true;
    return Grapnel;
});
