title: What is the difference between compress and cleancss options in grunt-contrib-less?
body: <p>Mates,</p>
  
  <p>I am using grunt-contrib-less for compiling all less files. I found two options doing the same for me. </p>
  
  <pre><code>compress: true 
  </code></pre>
  
  <p>and </p>
  
  <pre><code>cleancss: true
  </code></pre>
  
  <p>What is the difference between these two options? Anything I am missing? Should I be using both or just any?</p>
