//! Implementation of the various distribution aspects of the compiler.
//!
//! This module is responsible for creating tarballs of the standard library,
//! compiler, and documentation. This ends up being what we distribute to
//! everyone as well.
//!
//! No tarball is actually created literally in this file, but rather we shell
//! out to `rust-installer` still. This may one day be replaced with bits and
//! pieces of `rustup.rs`!
