Cargo Features

unveil-rs = { version = "0.1.2-alpha1", default-features = false, features = ["unveil-cli"] }
default = unveil-cli

The unveil-cli feature is set by default whenever unveil-rs is added without default-features = false somewhere in the dependency tree.

unveil-cli default = clap

Features from optional dependencies
