// This creates a webbundle which can be used in

// https://web.dev/web-bundles/.
//
// 1. Run this example: e.g. cargo run --example create-webbundle
// 2. Enable the runtime flag in Chrome: about://flags/#web-bundles
// 3. Drag and drop the generated bundle file (<crate_root>/examples/create-example.wbn) into Chrome.
// 4. You should see "Hello".
