title: Meaning of a double star (**) in a file path
body: <p>I was reading <a href="https://stackoverflow.com/a/32604767/2275800">here on Stack Overflow</a> about ** in a path, as in this example:</p>
  <pre><code>src/js/**/*.js
  </code></pre>
  <p>I would like to ask if &quot; ** &quot; means &quot;any nested directory&quot; please?!</p>
