The article means 'file in source control' - the specific context is that the author is one of the co-founders of Heroku where there is a whole separate (really nice) system for handling 'config variables' as part of your app deployments separate from source control.

You can also run foreman if you're not on Heroku. Put your environment variables in a `.env` file. The environment variables get sourced only to the environment of that process and not to the __whole__ system
