Super excited to see swift-configuration! There's a introduction on the Swift Forums at https://forums.swift.org/t/introducing-swift-configuration/82368; docs: https://swiftpackageindex.com/apple/swift-configuration/documentation/configuration; and code: https://github.com/apple/swift-configuration
Fills in the component for picking up configuration for server side apps that I've been shimming in somewhere between environment variables and using the argument parser for CLI options. Makes it way easier to wrangle for config when you use containers and cloud-based hosting.
