Every Config Setting can be overridden by convention by creating environment variables in the shell where you run box. This is idea for CI builds were you want to easily set ForgeBox API keys, or tweak settings for your build. You set set these as actual environment variables or Java system properties of the CLI.
The var must start with the text box_config_ and will be followed by the name of the setting.
For nested settings inside of a struct or array you can use underscores to represent dots.
