    {header Before publishing, please smoke test the packages!}

    1. Open {path ./fixtures/packaging/babel-standalone/dev.html} in the browser.
    2. It should say {quote "Hello world!"}
    3. Next go to {path ./fixtures/packaging} and run {command node build-all.js}
    4. Go to the repo root and {command npx pushstate-server . 9000}
    5. Open {link http://localhost:9000/fixtures/packaging}
    6. Verify every iframe shows {quote "Hello world!"}

    After completing the above steps, you can publish this release by running:
    {path   ${publishPath}}
  `
      .replace(/\n +/g, '\n')
      .trim()
