      description <<-DESC
      The Vagrant NFS Guest synced folders plugin enables you to use NFS exports from
      the Guest as a synced folder implementation. This allows the guest to utilise
      inotify (eg. file watchers) and other filesystem related functions that don't
      work across NFS from the host.
