I know this is an open source plugin not owned by gigaom, but did you want to support `go_config` `go-script-version.php` in it, @misterbisson? It feels like maybe not, but there's some nice benefits that we see from that dynamically generated config file.

```php
$script_version = apply_filters( 'go_config', array( 'version' => 1 ), 'go-script-version' );
```
