-// WARNING: If both config and environment-variable are set, the environment

-// preserved, but "key=value" pairs with an empty value (e.g. "key=") are ignored.
-// Tuples without a "=" produce an error.

-// It follows CSV rules for escaping, allowing "key=value" pairs to be quoted
-// if they must contain commas, which allows for multiple values for a single
-// header to be set. If a key is repeated in the list, later values override
-// prior values.
-//
-// For example, the following value:

-//	one=one-value,"two=two,value","three= a value with whitespace  ",four=,five=five=one,five=five-two
