Cargo Features

aeiou has no features set by default.

[dependencies]
aeiou = { version = "0.1.0", features = ["derive"] }
derive = aeiou-macros

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.
