Overview

The environment for a Goliath app can come from a variety of different sources. Due to the loading order of middleware, we must parse this out at load-time rather than run time.

Note that, as implemented, you cannot pass -e as part of a compound flag (e.g. ‘-sve production`) as it won’t be picked up. The example given would have to be provided as ‘-sv -e production`.
