Problem with component defined inside closure

Hi, I'm trying deomponentify with [move.js](https://github.com/visionmedia/move.js/blob/master/move.js#L1). Problem is, the entire component and the require function is defined inside a closure:

``` javascript
(function() {
function require(...)
...
}) ();
```

When this gets decomponentified, it becomes like this:

``` javascript
(function() {
function _require(...)
...
}) ();
module.exports = _require;
```

The problem is, `_require` is not available outside the closure, and module.exports ends up being undefined.
