//! Helper script to publish the wasm-bindgen suite of crates
//!
//! Usage:
//!
//! * First, compile this script
//! * Next, set cwd to the root of the wasm-bindgen repository
//! * Execute `./publish bump` to bump versions
//! * Send a PR
//! * Merge when green
//! * Execute `./publish publish` to publish crates
