How do I install bundletool? : <p>Although <a href="https://github.com/google/bundletool/releases" rel="noreferrer">the docs</a> mentioned</p>

<blockquote>
  <p>If you haven't already done so, download bundletool from the GitHub
  <a href="https://github.com/google/bundletool/releases" rel="noreferrer">repository</a>.</p>
</blockquote>

<p>However, the repo contains only a jar file. How do I install it so that I can run with 'bundletool' command just like the docs's example.</p>
