+;;; Commentary:
+;;;
+;;; INSTRUCTIONS
+;;;
+;;; This code contains a section of user-settable variables that you should
+;;; inspect prior to installation. Look past the end of the history list.
+;;; Set them up for your locale and the preferences of the majority of the
+;;; users. Otherwise the users may need to set a number of variables
+;;; themselves.
+;;; You particularly may want to change the default dictionary for your
+;;; country and language.
+;;;
+;;;
+;;; To fully install this, add this file to your GNU lisp directory and
+;;; compile it with M-X byte-compile-file. Then add the following to the
+;;; appropriate init file:
+;;;
+;;; (autoload 'ispell-word "ispell"
+;;; "Check the spelling of word in buffer." t)
+;;; (global-set-key "\e$" 'ispell-word)
+;;; (autoload 'ispell-region "ispell"
+;;; "Check the spelling of region." t)
+;;; (autoload 'ispell-buffer "ispell"
+;;; "Check the spelling of buffer." t)
+;;; (autoload 'ispell-complete-word "ispell"
+;;; "Look up current word in dictionary and try to complete it." t)
+;;; (autoload 'ispell-change-dictionary "ispell"
+;;; "Change ispell dictionary." t)
+;;; (autoload 'ispell-message "ispell"
+;;; "Check spelling of mail message or news post.")
+;;;
+;;; Depending on the mail system you use, you may want to include these:
+;;;
+;;; (add-hook 'news-inews-hook 'ispell-message)
+;;; (add-hook 'mail-send-hook 'ispell-message)
+;;; (add-hook 'mh-before-send-letter-hook 'ispell-message)
+;;;
+;;;
+;;; Ispell has a TeX parser and a nroff parser (the default).
+;;; The parsing is controlled by the variable ispell-parser. Currently
+;;; it is just a "toggle" between TeX and nroff, but if more parsers are
+;;; added it will be updated. See the variable description for more info.
+;;;
+;;;
+;;; TABLE OF CONTENTS
+;;;
+;;; ispell-word
+;;; ispell-region
+;;; ispell-buffer
+;;; ispell-message
+;;; ispell-continue
+;;; ispell-complete-word
+;;; ispell-complete-word-interior-frag
+;;; ispell-change-dictionary
+;;; ispell-kill-ispell
+;;; ispell-pdict-save
+;;;
+;;;
+;;; Commands in ispell-region:
+;;; Character replacement: Replace word with choice. May query-replace.
+;;; ' ': Accept word this time.
+;;; 'i': Accept word and insert into private dictionary.
+;;; 'a': Accept word for this session.
+;;; 'A': Accept word and place in buffer-local dictionary.
+;;; 'r': Replace word with typed-in value. Rechecked.
+;;; 'R': Replace word with typed-in value. Query-replaced in buffer. Rechecked.
+;;; '?': Show these commands
+;;; 'x': Exit spelling buffer. Move cursor to original point.
+;;; 'X': Exit spelling buffer. Leave cursor at the current point.
+;;; 'q': Quit spelling session (Kills ispell process).
+;;; 'l': Look up typed-in replacement in alternate dictionary. Wildcards okay.
+;;; 'u': Like 'i', but the word is lower-cased first.
+;;; 'm': Like 'i', but allows one to include dictionary completion info.
+;;; 'C-l': redraws screen
+;;; 'C-r': recursive edit
+;;; 'C-z': suspend emacs
+;;;
+;;; Buffer-Local features:
+;;; There are a number of buffer-local features that can be used to customize
+;;; ispell for the current buffer. This includes language dictionaries,
+;;; personal dictionaries, parsing, and local word spellings. Each of these
+;;; local customizations are done either through local variables, or by
+;;; including the keyword and argument(s) at the end of the buffer (usually
+;;; prefixed by the comment characters). See the end of this file for
+;;; examples. The local keywords and variables are:
+;;;
+;;; ispell-dictionary-keyword language-dictionary
+;;; uses local variable ispell-local-dictionary
+;;; ispell-pdict-keyword personal-dictionary
+;;; uses local variable ispell-local-pdict
+;;; ispell-parsing-keyword mode-arg extended-char-arg
+;;; ispell-words-keyword any number of local word spellings
+;;;
+;;;
+;;; BUGS:
+;;; Highlighting in version 19 still doesn't work on tty's.
+;;; On some versions of emacs, growing the minibuffer fails.
+;;;

+;;; Revision 2.20 1993/06/30 14:09:04 stevens
+;;;
+;;; Debugging and contributions by: Boris Aronov, Rik Faith, Chris Moore,

+;;; Assure context on ispell-command-loop. Window lossage in look cmd fixed.
+;;; Due to pervasive opinion, common-lisp package syntax removed. Display
+;;; problem when not highlighting.
+;;;
+;;; Revision 2.19 1992/01/10 10:54:08 geoff
+;;; Make another attempt at fixing the "Bogus, dude" problem. This one is
+;;; less elegant, but has the advantage of working.
+;;;
+;;; Revision 2.18 1992/01/07 10:04:52 geoff
+;;; Fix the "Bogus, Dude" problem in ispell-word.
+;;;
+;;; Revision 2.17 1991/09/12 00:01:42 geoff
+;;; Add some changes to make ispell-complete-word work better, though
+;;; still not perfectly.
+;;;
+;;; Revision 2.16 91/09/04 18:00:52 geoff
+;;; More updates from Sebastian, to make the multiple-dictionary support
+;;; more flexible.
+;;;
+;;; Revision 2.15 91/09/04 17:30:02 geoff
+;;; Sebastian Kremer's tib support
+;;;
+;;; Revision 2.14 91/09/04 16:19:37 geoff
+;;; Don't do set-window-start if the move-to-window-line moved us
+;;; downward, rather than upward. This prevents getting the buffer all
+;;; confused. Also, don't use the "not-modified" function to clear the
+;;; modification flag; instead use set-buffer-modified-p. This prevents
+;;; extra messages from flashing.
+;;;
+;;; Revision 2.13 91/09/04 14:35:41 geoff
+;;; Fix a spelling error in a comment. Add code to handshake with the
+;;; ispell process before sending anything to it.
+;;;
+;;; Revision 2.12 91/09/03 20:14:21 geoff
+;;; Add Sebastian Kremer's multiple-language support.

+;;; This file has overgone a major overhaul to be compatible with ispell
+;;; version 2.1. Most of the functions have been totally rewritten, and
+;;; many user-accessible variables have been added. The syntax table has
+;;; been removed since it didn't work properly anyway, and a filter is
+;;; used rather than a buffer. Regular expressions are used based on
+;;; ispell's internal definition of characters (see ispell(4)).
+;;; Some new updates:
+;;; - Updated to version 3.0 to include terse processing.
+;;; - Added a variable for the look command.
+;;; - Fixed a bug in ispell-word when cursor is far away from the word
+;;; that is to be checked.
+;;; - Ispell places the incorrect word or guess in the minibuffer now.
+;;; - fixed a bug with 'l' option when multiple windows are on the screen.
+;;; - lookup-words just didn't work with the process filter. Fixed.
+;;; - Rewrote the process filter to make it cleaner and more robust
+;;; in the event of a continued line not being completed.
+;;; - Made ispell-init-process more robust in handling errors.
+;;; - Fixed bug in continuation location after a region has been modified by
+;;; correcting a misspelling.

+;;; Sebastian Kremer <sk@thp.uni-koeln.de>
+;;; Wed Aug 7 14:02:17 MET DST 1991
+;;; - Ported ispell-complete-word from Ispell 2 to Ispell 3.
+;;; - Added ispell-kill-ispell command.
+;;; - Added ispell-dictionary and ispell-dictionary-alist variables to
+;;; support other than default language. See their docstrings and
+;;; command ispell-change-dictionary.
+;;; - (ispelled it :-)
+;;; - Added ispell-skip-tib variable to support the tib bibliography
+;;; program.

+
+DICTIONARY-NAME is a possible value of variable ispell-dictionary, nil
+means the default dictionary.
+
+CASECHARS is a regular expression of valid characters that comprise a
+word.
+
+NOT-CASECHARS is the opposite regexp of CASECHARS.
+
+OTHERCHARS is a regular expression of other characters that are valid
+in word constructs. Otherchars cannot be adjacent to each other in a
+word, nor can they begin or end a word. This implies we can't check
+\"Stevens'\" as a correct possessive and other correct formations.
+
+Hint: regexp syntax requires the hyphen to be declared first here.
+
+MANY-OTHERCHARS-P is non-nil if many otherchars are to be allowed in a
+word instead of only one.
+
+ISPELL-ARGS is a list of additional arguments passed to the ispell
+subprocess.
+
+EXTENDED-CHARACTER-MODE should be used when dictionaries are used which
+have been configured in ispell's parse.y. (For example, umlauts
+can be encoded as \\\"a, a\\\", \"a, ...) Defaults are ~tex and ~nroff
+in english. This has the same effect as the command-line `-T' option.
+The buffer Major Mode controls ispell's parsing in tex or nroff mode,
+but the dictionary can control the extended character mode.
+Both defaults can be overruled in a buffer-local fashion. See
+ispell-parsing-keyword for details on this.
