In the README it says:

You pass a list of urls to the loader, along with a method for checking that your page is ready, and a callback to call when it is.

The method for checking if the page is ready seems to be actually the method that is checking if the library has loaded, for not loading it twice (the test method).

Is there a way for deferring the loading of the script only after the page has been completely loaded? This is useful for page load speed.

Very nice library, simple and useful - Thanks!
