//! This crate provides two mechanisms for configuring the behaviour of the Servo engine.
//! - The [`opts`] module exposes a set of global flags that are initialized once
//! and cannot be changed at runtime.
//! - The [`prefs`] module provides a mechanism to get and set global preference
//! values that can be changed at runtime.
