//! `foreman`: Rust build script assistant
//!
//! "Don't pick up those environment variables yourself.
//!  Just tell the foreman what to do with the cargo."
//!
//! This crate contains utilities for build scripts to talk to Cargo, abstracting away the input
//! (via special environment variables that Cargo sets) and output (via special patterns that the
//! build script prints to stdout).
