title: How to know what version of UglifyCSS was installed?
body: <p>I has installed <code>UglifyCSS</code> globally with command:</p>
  
  <pre><code>npm install -g uglifycss
  </code></pre>
  
  <p>How can I get current version of installed <code>UglifyCSS</code>?</p>
  
  <p><strong>P.S.</strong></p>
  
  <p>Version of <code>UglifyJS</code> I check with command:</p>
  
  <pre><code>uglifyjs -V
  </code></pre>
  
  <p>But when I try similar command for <code>UglifyCSS</code>:</p>
  
  <pre><code>uglifycss -V
  </code></pre>
  
  <p>I had an error:</p>
  
  <pre><code>unable to process "-V" with Error: ENOENT, no such file or directory '-V'
  </code></pre>
  
  <p>Same error when I try <code>-v</code> and <code>--version</code></p>
