Cargo Features

quake-files has no features set by default.

[dependencies]
quake-files = { version = "0.1.0", features = ["nightly"] }
nightly = clippy

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.

clippy nightly?
