-//! SIMD vectors.
-//!
-//! These types can be used for accessing basic SIMD operations. Each of them
-//! implements the standard arithmetic operator traits (Add, Sub, Mul, Div,
-//! Rem, Shl, Shr) through compiler magic, rather than explicitly. Currently
-//! comparison operators are not implemented. To use SSE3+, you must enable
-//! the features, like `-C target-feature=sse3,sse4.1,sse4.2`, or a more
-//! specific `target-cpu`. No other SIMD intrinsics or high-level wrappers are
-//! provided beyond this module.
-//!
-//! ```rust
-//! # #![feature(core_simd)]
-//! fn main() {
-//!     use std::simd::f32x4;
-//!     let a = f32x4(40.0, 41.0, 42.0, 43.0);
-//!     let b = f32x4(1.0, 1.1, 3.4, 9.8);
-//!     println!("{:?}", a + b);
-//! }
-//! ```
-//!
-//! # Stability Note
-//!
-//! These are all experimental. The interface may change entirely, without
-//! warning.
