title: What does api.imply do?
body: <p>From the <a href="http://docs.meteor.com/#/full/pack_api_imply" rel="nofollow noreferrer">Meteor docs</a>:</p>
  
  <blockquote>
    <p>Give users of this package access to another package (by passing in the string <code>packagename</code>) or a collection of packages (by passing in an array of strings <code>[packagename1, packagename2]</code>).</p>
  </blockquote>
  
  <p>I have no idea what it means.<br>
  From <a href="https://stackoverflow.com/questions/25607825/if-i-use-api-imply-in-package-js-do-i-have-to-use-api-use-for-the-same-package">this question</a> I know that <code>imply</code> can be employed with <code>use</code>.</p>
  
  <p>What does <code>api.imply</code> do?<br>
  What's exactly the difference between <code>api.use</code> and <code>api.imply</code>?</p>
