title: How do I integrate abook with a carddav server?
body: <p>I'm running Nextcloud, and my contacts are synced to my laptop with <code>vdirsyncer</code>, which leaves me with a directory full of <code>.vcf</code> files. I'd like to abook to be able to read and edit those but I'm not quite sure how to make that happen. </p>
  
  <p>Is that even possible? Or am I just dreaming? </p>
