+//! # Features
+//!
+//! This crate has two Cargo features: `window` and `headless`.
+//!
+//! - `window` allows you to create regular windows and enables the `WindowBuilder` object.
+//! - `headless` allows you to do headless rendering, and enables
+//! the `HeadlessRendererBuilder` object.
+//!
+//! By default only `window` is enabled.
