//! The `servoshell` test application.

//! Creates a `Servo` instance with a example implementation of a working
//! web browser.
//!
//! This browser's implementation of `WindowMethods` is built on top
//! of [winit], the cross-platform windowing library.
//!
//! For the engine itself look next door in `components/servo/lib.rs`.
