title: Babel compile path with wildcard but keep folder structure
body: <p>Hi I am testing how can I give path with wildcards to babel and output the same structure.</p>
  
  <pre><code>|src
  |---A
  |-----src
  |-----------a.js
  |---B
  |-----src
  |-----------b.js
  </code></pre>
  
  <p>If I run <code>babel root/**/src -d lib/**/lib</code>, it will output</p>
  
  <pre><code>|lib
  |---**
  |-----lib
  |-----------a.js
  |-----------b.js
  </code></pre>
  
  <p>However, what I want is,</p>
  
  <pre><code>|lib
  |---A
  |-----lib
  |-----------a.js
  |---B
  |-----lib
  |-----------b.js
  </code></pre>
  
  <p>How can I do it?</p>
