;;; Commentary:
|
|
;;
|
|
;; Flyspell is a minor Emacs mode performing on-the-fly spelling
|
|
;; checking.
|
|
;;
|
|
;; To enable Flyspell minor mode, type M-x flyspell-mode.
|
|
;; This applies only to the current buffer.
|
|
;;
|
|
;; To enable Flyspell in text representing computer programs, type
|
|
;; M-x flyspell-prog-mode.
|
|
;; In that mode only text inside comments is checked.
|
|
;;
|
|
;; Note: consider setting the variable ispell-parser to `tex' to
|
|
;; avoid TeX command checking; use `(setq ispell-parser 'tex)'.
|
|
;;
|
|
;; Some user variables control the behavior of flyspell. They are
|
|
;; those defined under the `User variables' comment.
