25 ;;; Commentary:
26 ;;
27 ;; Flyspell is a minor Emacs mode performing on-the-fly spelling
28 ;; checking.
29 ;;
30 ;; To enable Flyspell minor mode, type M-x flyspell-mode.
31 ;; This applies only to the current buffer.
32 ;;
33 ;; To enable Flyspell in text representing computer programs, type
34 ;; M-x flyspell-prog-mode.
35 ;; In that mode only text inside comments is checked.
36 ;;
37 ;; Note: consider setting the variable ispell-parser to `tex' to
38 ;; avoid TeX command checking; use `(setq ispell-parser 'tex)'.
39 ;;
40 ;; Some user variables control the behavior of flyspell. They are
41 ;; those defined under the `User variables' comment.

77 It should be a list of (LANGUAGE . EXCEPTION-LIST). LANGUAGE is matched
78 against the current dictionary and EXCEPTION-LIST is a list of strings.
79 The duplicated word is downcased before it is compared with the exceptions."
84 "Non-nil means, sort the corrections alphabetically before popping them."
90 "The maximum distance for finding duplicates of unrecognized words.
91 This applies to the feature that when a word is not found in the dictionary,
92 if the same spelling occurs elsewhere in the buffer,
93 Flyspell uses a different face (`flyspell-duplicate') to highlight it.
94 This variable specifies how far to search to find such a duplicate.
95 -1 means no limit (search the whole buffer).
96 0 means do not search for duplicate unrecognized spellings."

172 The third is either the symbol `doublon' or the list

184 If the variable `ispell-local-dictionary' or `ispell-dictionary' is non-nil
185 when flyspell is started, the value of that variable is used instead
186 of `flyspell-default-dictionary' to select the default dictionary.
