How does one run a locomotive app without using the lcm command?
In other words, where is `module.exports = app;` happening?
I just want to do something like `node app.js -p 3000`, but I'm having trouble finding the place for it.
I'm assuming I need to create a file that's something like this, but I can't find documentation for how it's done.
```javascript
(function () {
'use strict';
var locomotive = require('locomotive')
, app
;
app = locomotive.createServer(__directory);
module.exports = app;
}());
```
