//! # Rapier
//!
//! Rapier is a set of two Rust crates `rapier2d` and `rapier3d` for efficient cross-platform
//! physics simulation. It target application include video games, animation, robotics, etc.
//!
//! Rapier has some unique features for collaborative applications:
//! - The ability to snapshot the state of the physics engine, and restore it later.
//! - The ability to run a perfectly deterministic simulation on different machine, as long as they
//! are compliant with the IEEE 754-2008 floating point standard.
// FIXME: deny that
