Subvariables work by using the [variable_name:variable_default] syntax within an .env template. You can use as many as you wish in a row, but they cannot be nested.

Why barbara?

Because Barbara Liskov created the Liskov Substituion Principle and is a prolific contributor to computer science and software engineering. Barbara is one of the Newton’s metaphorical giants that enables us to see further. I humbly dedicate my project to her and her contributions and offer this project to its consumers with a license befitting that dedication.
