title: How to get Cygwin DLL version before installation (command line output)?
body: <p>Periodically downloaded <a href="https://www.cygwin.com/" rel="nofollow noreferrer">Cygwin</a>'s <code>setup.exe</code> installs newer version of Cygwin DLL.</p>
  
  <p>The installer GUI shows the version, but I want to get it using command line in the output, for example:</p>
  
  <pre><code>setup.exe --something-like-version
  </code></pre>
  
  <p><a href="https://stackoverflow.com/questions/4506287/how-would-i-find-the-cygwin-version-which-has-been-installed-on-my-machine">This answer</a> shows how to get this after installation, but it's too late for me.</p>
