Cargo Features

[dependencies]
cargo-extras = { version = "0.3.0", default-features = false, features = ["color"] }
default = color

The color feature is set by default whenever cargo-extras is added without default-features = false somewhere in the dependency tree.

color default = ansi_term

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.
