//! ### This Crate
//! The "bevy" crate is just a container crate that makes it easier to consume Bevy components.
//! The defaults provide a "full" engine experience, but you can easily enable / disable features
//! in your project's Cargo.toml to meet your specific needs. See Bevy's Cargo.toml for a full list of features available.
//!
//!
//! If you prefer it, you can also consume the individual bevy crates directly.
