title: MITMPROXY make output human readable to file
body: <p>My system:</p>
  
  <pre><code>Ubuntu 16.04
  Mitmproxy version 3.0.4
  Python version 3.5.2
  </code></pre>
  
  <p>I've successfully installed <code>mitmproxy</code> from: <a href="https://docs.mitmproxy.org/stable/overview-installation/" rel="noreferrer">docs.mitmproxy.org</a> on my server. But now I got confused how to save log mitmproxy to file? I try use <code>mitmdump --mode transparent --showhost -p 9001 -w output_file</code></p>
  
  <p>While I open <code>output_file</code>, it's not human readable. I read the docs and try scripts from the mitmproxy's Github, but no clue.</p>
  
  <p>Anyone know how to save log mitmproxy to file, but human readable?<br>
  Thank you!</p>
