//! See https://github.com/matklad/cargo-xtask/.
//!
//! This binary defines various auxiliary build commands, which are not
//! expressible with just `cargo`. Notably, it provides tests via `cargo test -p xtask`
//! for code generation and `cargo xtask install` for installation of
//! rust-analyzer server and client.
//!
//! This binary is integrated into the `cargo` command line by using an alias in
//! `.cargo/config`.
