How to Load Laravel 5 settings on a Custom PHP Script?

I'm writing a script which is not using the whole Laravel Environment, so ideally I only need some bits of the whole framework.

I need to fetch the settings in the .env files and possibly be able to use the database via the query builder (http://ift.tt/2xCKG5c) instead of the ORM.

Any suggestion on how can I do it?
