;;; Commentary:
;; This package provides `ivy-read' as an alternative to
;; `completing-read' and similar functions.
;;
;; There's no intricate code to determine the best candidate.
;; Instead, the user can navigate to it with `ivy-next-line' and
;; `ivy-previous-line'.
;;
;; The matching is done by splitting the input text by spaces and
;; re-building it into a regex.
;; So "for example" is transformed into "\\(for\\).*\\(example\\)".
