;;; Commentary:
;; Jinx is a fast just-in-time spell-checker for Emacs. Jinx
;; highlights misspelled words in the text of the visible portion of
;; the buffer. For efficiency, Jinx highlights misspellings lazily,
;; recognizes window boundaries and text folding, if any. For
;; example, when unfolding or scrolling, only the newly visible part
;; of the text is checked if it has not been checked before. Each
;; misspelling can be corrected from a list of dictionary words
;; presented as a completion menu.
;; Installing Jinx is straight-forward and configuring should not need
;; much intervention. Jinx can be used completely on its own, but can
;; also safely co-exist with Emacs's built-in spell-checker Ispell.
;; Jinx's high performance and low resource usage comes from directly
;; calling the API of the Enchant library, see
;; https://rrthomas.github.io/enchant/. Jinx automatically compiles
;; jinx-mod.c and loads the dynamic module at startup. By binding
;; directly to the native Enchant API, Jinx avoids slower
;; inter-process communication.
;; See the manual for further information.
