-The package allows for two different back ends for the overview: `helm` and 
`ivy`.  You can set the
-one you want by customizing `swiper-completion-method`.
+The package uses the `ivy` back end for the overview, see also

-;;; Commentary:
-;;
-;; This package gives an overview of the current regex search
-;; candidates.  The search regex can be split into groups with a
-;; space.  Each group is highlighted with a different face.
-;;
-;; The overview back end is `helm'.
-;;
-;; It can double as a quick `regex-builder', although only single
-;; lines will be matched.
