;; 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

The default flyspell behavior is to highlight incorrect words.
With no argument, this command toggles Flyspell mode.
With a prefix argument ARG, turn Flyspell minor mode on iff ARG is positive.
