using require.js with FB SDK

I would like to load FB SDK using require.js.

my test case is something like this:

test.js:

require([        
     'libs/facebook/fb'
     ], function(FB){
     FB.api("/me", function(){});
));

I would like to have test.js run only after FB SDK is loaded, and have FB ready for it.

Any thoughts on how this can be achieved? what should my wrapper (libs/facebook/fb.js) have?
