      Web Distributed Authoring and Versioning (WebDAV), an extension to
      the HTTP-protocol, allows authoring of resources on a remote web
      server. davfs2 provides the ability to access such resources like
      a typical filesystem, allowing for use by standard applications
      with no built-in support for WebDAV.
