+ ;;; 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.
