Cargo Features

mini-config has no features set by default.

[dependencies]
mini-config = { version = "0.1.3", features = ["derive"] }
derive = mini-config-derive

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
