title: Can I use a Crosswalk extension with Cordova?
body: <p>I have a Crosswalk extension (and not a Cordova plugin), and I want to use it in a Cordova application (which uses the Crosswalk webview via the cordova-plugin-crosswalk-webview). </p>
  
  <p>Is this possible?
  How do I configure it?</p>
