-@end iftex
-
-@AUCTeX{} is an integrated environment for editing @LaTeX{}, @ConTeXt{},
-doc@TeX{}, Texinfo, and @TeX{} files.
-
-Although @AUCTeX{} contains a large number of features, there are no
-reasons to despair.  You can continue to write @TeX{} and @LaTeX{}
-documents the way you are used to, and only start using the multiple
-features in small steps.  @AUCTeX{} is not monolithic, each feature
-described in this manual is useful by itself, but together they provide
-an environment where you will make very few @LaTeX{} errors, and makes
-it easy to find the errors that may slip through anyway.
-
-It is a good idea to make a printout of @AUCTeX{}'s reference card
-@file{tex-ref.tex} or one of its typeset versions.
-
-If you want to make @AUCTeX{} aware of style files and multifile
-documents right away, insert the following in your init file (usually
-@file{~/.emacs.d/init.el}).
-
-@lisp
-(setq TeX-auto-save t)
-(setq TeX-parse-self t)
-(setq-default TeX-master nil)
-@end lisp
-
-Another thing you should enable is Ref@TeX{}, a comprehensive solution
-for managing cross references, bibliographies, indices, document
-navigation and a few other things.  (@xref{Installation,,,reftex,The
-Ref@TeX{} manual}.)
-
-For detailed information about the @previewlatex{} subsystem of
-@AUCTeX{}, see @ref{Top,,Introduction,preview-latex,The @previewlatex{}
-Manual}.
-
-There is a mailing list for general discussion about @AUCTeX{}: write a
-mail with ``subscribe'' in the subject to
-@email{auctex-request@@gnu.org} to join it.  Send contributions to
-@email{auctex@@gnu.org}.
-
-Bug reports should go to @email{bug-auctex@@gnu.org}, suggestions for
-new features, and pleas for help should go to either
-@email{auctex-devel@@gnu.org} (the @AUCTeX{} developers), or to
-@email{auctex@@gnu.org} if they might have general interest.  Please use
-the command @kbd{M-x TeX-submit-bug-report @key{RET}} to report bugs if
-possible.  You can subscribe to a low-volume announcement list by
-sending ``subscribe'' in the subject of a mail to
-@email{info-auctex-request@@gnu.org}.

-
-The most commonly used commands/macros of @AUCTeX{} are those which
-simply insert templates for often used @TeX{}, @LaTeX{}, or @ConTeXt{}
-constructs, like font changes, handling of environments, etc.  These
-features are very simple, and easy to learn, and help you avoid mistakes
-like mismatched braces, or @samp{\begin@{@}}-@samp{\end@{@}} pairs.
-
-Apart from that this chapter contains a description of some features for
-entering more specialized sorts of text, for formatting the source by
-indenting and filling and for navigating through the document.

-@subheading Quotation Marks
-
-In @TeX{}, literal double quotes @samp{"like this"} are seldom used,
-instead two single quotes are used @samp{``like this''}.  To help you
-insert these efficiently, @AUCTeX{} allows you to continue to press
-@kbd{"} to insert two single quotes.  To get a literal double quote,
-press @kbd{"} twice.
-
-@deffn Command TeX-insert-quote @var{count}
-@kindex "
-(@kbd{"}) Insert the appropriate quote marks for @TeX{}.
-
-Inserts the value of @code{TeX-open-quote} (normally @samp{``}) or
-@code{TeX-close-quote} (normally @samp{''}) depending on the context.
-With prefix argument, always inserts @samp{"} characters.
-@end deffn
-
-@defopt TeX-open-quote
-String inserted by typing @kbd{"} to open a quotation.
-(@xref{European}, for language-specific quotation mark insertion.)
-@end defopt
-
-@defopt TeX-close-quote
-String inserted by typing @kbd{"} to close a quotation.
-(@xref{European}, for language-specific quotation mark insertion.)
-@end defopt
-
-@defopt TeX-quote-after-quote
-Determines the behavior of @kbd{"}.  If it is non-nil, typing @kbd{"}
-will insert a literal double quote.  The respective values of
-@code{TeX-open-quote} and @code{TeX-close-quote} will be inserted
-after typing @kbd{"} once again.
-@end defopt
-
-The @samp{babel} package provides special support for the requirements
-of typesetting quotation marks in many different languages.  If you use
-this package, either directly or by loading a language-specific style
-file, you should also use the special commands for quote insertion
-instead of the standard quotes shown above.  @AUCTeX{} is able to
-recognize several of these languages and will change quote insertion
-accordingly.  @xref{European}, for details about this feature and how to
-control it.
-
-@vindex LaTeX-csquotes-open-quote
-@vindex LaTeX-csquotes-close-quote
-@vindex LaTeX-csquotes-quote-after-quote
-In case you are using the @samp{csquotes} package, you should customize
-@code{LaTeX-csquotes-open-quote}, @code{LaTeX-csquotes-close-quote} and
-@code{LaTeX-csquotes-quote-after-quote}.  The quotation characters will
-only be used if both variables---@code{LaTeX-csquotes-open-quote} and
-@code{LaTeX-csquotes-close-quote}---are non-empty strings.  But then the
-@samp{csquotes}-related values will take precedence over the
-language-specific ones.
-
-@subheading Dollar Signs
-
-In @AUCTeX{}, dollar signs should match like they do in @TeX{}.  This
-has been partially implemented, we assume dollar signs always match
-within a paragraph.  By default, the first @samp{$} you insert in a
-paragraph will do nothing special.  The second @samp{$} will match the
-first.  This will be indicated by moving the cursor temporarily over the
-first dollar sign.
-
-@deffn Command TeX-insert-dollar @var{arg}
-@kindex $
-(@kbd{$}) Insert dollar sign.
-
-Show matching dollar sign if this dollar sign end the @TeX{} math mode.
-
-With optional @var{arg}, insert that many dollar signs.
-@end deffn
-
-@TeX{} and @LaTeX{} users often look for a way to insert inline
-equations like @samp{$...$} or @samp{\(...\)} simply typing @kbd{$}.
-@AUCTeX{} helps them through the customizable variable
-@code{TeX-electric-math}.
-
-@defopt TeX-electric-math
-If the variable is non-nil and you type @kbd{$} outside math mode,
-@AUCTeX{} will automatically insert the opening and closing symbols for
-an inline equation and put the point between them.  The opening symbol
-will blink when @code{blink-matching-paren} is non-nil.  If
-@code{TeX-electric-math} is nil, typing @kbd{$} simply inserts @samp{$}
-at point, this is the default.
-
-Besides @code{nil}, possible values for this variable are @code{(cons
-"$" "$")} for @TeX{} inline equations @samp{$...$}, and @code{(cons
-"\\(" "\\)")} for @LaTeX{} inline equations @samp{\(...\)}.
-
-If the variable is non-nil and point is inside math mode right between a
-couple of single dollars, pressing @kbd{$} will insert another pair of
-dollar signs and leave the point between them.  Thus, if
-@code{TeX-electric-math} is set to @code{(cons "$" "$")} you can easily
-obtain a @TeX{} display equation @samp{$$...$$} by pressing @kbd{$}
-twice in a row.  (Note that you should not use double dollar signs in
-@LaTeX{} because this practice can lead to wrong spacing in typeset
-documents.)
-
-In addition, when the variable is non-nil and there is an active region
-outside math mode, typing @kbd{$} will put around the active region
-symbols for opening and closing inline equation and keep the region
-active, leaving point after the closing symbol.  By pressing repeatedly
-@kbd{$} while the region is active you can toggle between an inline
-equation, a display equation, and no equation.  To be precise,
-@samp{$...$} is replaced by @samp{$$...$$}, whereas @samp{\(...\)} is
-replaced by @samp{\[...\]}.
-@end defopt
-
-If you want to automatically insert @samp{$...$} in plain @TeX{} files,
-and @samp{\(...\)} in @LaTeX{} files by pressing @kbd{$}, add the
-following to your init file
-@lisp
-(add-hook 'plain-TeX-mode-hook
-          (lambda () (set (make-local-variable 'TeX-electric-math)
-                          (cons "$" "$"))))
-(add-hook 'LaTeX-mode-hook
-          (lambda () (set (make-local-variable 'TeX-electric-math)
-                          (cons "\\(" "\\)"))))
-@end lisp
-
-Note that Texinfo mode does nothing special for @kbd{$}.  It inserts
-dollar sign(s) just in the same way as the other normal keys do.
-
-@subheading Braces
-
-To avoid unbalanced braces, it is useful to insert them pairwise.  You
-can do this by typing @kbd{C-c @{}.
-
-@deffn Command TeX-insert-braces
-@kindex C-c @{
-(@kbd{C-c @{}) Make a pair of braces and position the cursor
-to type inside of them.  If there is an active region, put braces around
-it and leave point after the closing brace.
-@end deffn
-
-When writing complex math formulas in @LaTeX{} documents, you
-sometimes need to adjust the size of braces with pairs of macros like
-@samp{\left}-@samp{\right}, @samp{\bigl}-@samp{\bigr} and so on.  You
-can avoid unbalanced pairs with the help of @code{TeX-insert-macro},
-bound to @kbd{C-c C-m} or @kbd{C-c @key{RET}} (@pxref{Completion}).
-If you insert left size adjusting macros such as @samp{\left},
-@samp{\bigl} etc.@: with @code{TeX-insert-macro}, it asks for left brace
-to use and supplies automatically right size adjusting macros such as
-@samp{\right}, @samp{\bigr} etc.@: and corresponding right brace in
-addtion to the intended left macro and left brace.
-
-The completion by @code{TeX-insert-macro} also applies when entering
-macros such as @samp{\langle}, @samp{\lfloor} and @samp{\lceil}, which
-produce the left part of the paired braces.  For example, inserting
-@samp{\lfloor} by @kbd{C-c C-m} is immediately followed by the
-insertion of @samp{\rfloor}.  In addition, if the point was located
-just after @samp{\left} or its friends, the corresponding
-@samp{\right} etc.@: will be inserted in front of @samp{\rfloor}.
-In both cases, active region is honored.
-
-As a side effect, when @code{LaTeX-math-mode} (@pxref{Mathematics}) is
-on, just typing @kbd{`(} inserts not only @samp{\langle}, but also
-@samp{\rangle}.
-
-If you do not like such auto completion at all, it can be disabled by a
-user option.
-
-@defopt TeX-arg-right-insert-p
-If this option is turned off, the automatic supply of the right macros
-and braces is suppressed.
-@end defopt
-
-@kindex (
-@kindex @{
-@kindex [
-When you edit @LaTeX{} documents, you can enable automatic brace
-pairing when typing @kbd{(}, @kbd{@{} and @kbd{[}.
-
-@defopt LaTeX-electric-left-right-brace
-If this option is on, just typing @kbd{(}, @kbd{@{} or @kbd{[}
-immediately adds the corresponding right brace @samp{)}, @samp{@}} or
-@samp{]}.  The point is left after the opening brace.  If there is an
-active region, braces are put around it.
-
-They recognize the preceding backslash or size adjusting macros such
-as @samp{\left}, @samp{\bigl} etc., so the following completions will
-occur:
-@itemize @bullet
-
-@item
-(when typing single left brace)
-@itemize @minus
-
-@item
-@samp{(} -> @samp{()}
-
-@item
-@samp{@{} -> @samp{@{@}}
-
-@item
-@samp{[} -> @samp{[]}
-@end itemize
-
-@item
-(when typing left brace just after a backslash)
-@itemize @minus
-
-@item
-@samp{\(} -> @samp{\(\)}
-
-@item
-@samp{\@{} -> @samp{\@{\@}}
-
-@item
-@samp{\[} -> @samp{\[\]}
-@end itemize
-
-@item
-(when typing just after @samp{\left} or @samp{\bigl})
-@itemize @minus
-
-@item
-@samp{\left(} -> @samp{\left(\right)}
-
-@item
-@samp{\bigl[} -> @samp{\bigl[\bigr]}
-@end itemize
-
-@item
-(when typing just after @samp{\Bigl\})
-@itemize @minus
-
-@item
-@samp{\Bigl\@{} -> @samp{\Bigl\@{\Bigr\@}}
-
-@end itemize
-
-@end itemize
-
-This auto completion feature may be a bit annoying when editing an
-already existing @LaTeX{} document.  In that case, use @kbd{C-u 1} or
-@kbd{C-q} before typing @kbd{(}, @kbd{@{} or @kbd{[}.  Then no
-completion is done and just a single left brace is inserted.  In fact,
-with optional prefix @var{arg}, just that many open braces are
-inserted without any completion.

-A large apparatus is available that supports insertions of environments,
-that is @samp{\begin@{@}} --- @samp{\end@{@}} pairs.
-
-@AUCTeX{} is aware of most of the actual environments available in a
-specific document.  This is achieved by examining your
-@samp{\documentclass} command, and consulting a precompiled list of
-environments available in a large number of styles.
-
-Most of these are described further in the following sections, and you
-may easily specify more.  @xref{Customizing Environments}.
-
-You insert an environment with @kbd{C-c C-e}, and select an environment
-type.  Depending on the environment, @AUCTeX{} may ask more questions
-about the optional parts of the selected environment type.  With
-@kbd{C-u C-c C-e} you will change the current environment.
-
-@deffn Command LaTeX-environment @var{arg}
-@kindex C-c C-e
-(@kbd{C-c C-e})  @AUCTeX{} will prompt you for an environment
-to insert.  At this prompt, you may press @key{TAB} or @key{SPC} to
-complete a partially written name, and/or to get a list of available
-environments.  After selection of a specific environment @AUCTeX{} may
-prompt you for further specifications.
-
-If the optional argument @var{arg} is non-nil (i.e.@: you have given a
-prefix argument), the current environment is modified and no new
-environment is inserted.
-@end deffn
-
-@AUCTeX{} helps you adding labels to environments which use them, such
-as @samp{equation}, @samp{figure}, @samp{table}, etc@dots{}  When you
-insert one of the supported environments with @kbd{C-c C-e}, you will be
-automatically prompted for a label.  You can select the prefix to be
-used for such environments with the @code{LaTeX-label-alist} variable.
-@defopt LaTeX-label-alist
-List the prefixes to be used for the label of each supported
-environment.

-This is an alist whose car is the environment name, and the cdr either
-the prefix or a symbol referring to one.

-If the name is not found, or if the cdr is nil, no label is
-automatically inserted for that environment.
-
-If you want to automatically insert a label for a environment but with
-an empty prefix, use the empty string @code{""} as the cdr of the
-corresponding entry.

-inserted or, as the first choice the value of the variable
-@code{LaTeX-default-environment}.
-
-@defopt LaTeX-default-environment

-@end deffn
-
-@defvar TeX-complete-list
-List of ways to complete the preceding text.
-
-Each entry is a list with the following elements:
-
-@enumerate
-@item
-Regexp matching the preceding text or a predicate of arity 0 which
-returns non-nil and sets `match-data' appropriately if it is applicable.
-@item
-A number indicating the subgroup in the regexp containing the text.
-@item
-A function returning an alist of possible completions.
-@item
-Text to append after a succesful completion.
-@end enumerate
-
-Or alternatively:
-
-@enumerate
-@item
-Regexp matching the preceding text.
-@item
-Function to do the actual completion.
-@end enumerate
-@end defvar
-
-More recent Emacs versions have a new completion mechanism.  Modes may
-define and register custom @code{completion-at-point} functions and when the
-user invokes @code{completion-at-point} (usually bound to
-@kbd{M-@key{TAB}}), all such registered functions are consulted for
-checking for possible completions.  Modern completion UIs like
-@i{company-mode} support this completion-at-point facility.
-
-@defun TeX--completion-at-point
-@AUCTeX{}'s completion-at-point function which is automatically added to
-@code{completion-at-point-functions} in @TeX{} and @LaTeX{} buffers.
-
-It offers the same completion candidates as would
-@code{TeX-complete-symbol} (and is also controlled by
-@code{TeX-complete-list}) except that it doesn't fall back on
-@code{ispell-complete-word} which would be awkward with completion UIs
-like @i{company-mode}.
-@end defun
-
-A more direct way to insert a macro is with @code{TeX-insert-macro},
-bound to @kbd{C-c C-m} which is equivalent to @kbd{C-c @key{RET}}.  It
-has the advantage over completion that it knows about the argument of
-most standard @LaTeX{} macros, and will prompt for them.  It also knows
-about the type of the arguments, so it will for example give completion
-for the argument to @samp{\include}.  Some examples are listed below.
-
-@deffn Command TeX-insert-macro
-@kindex C-c C-m
-(@kbd{C-c C-m} or @kbd{C-c @key{RET}}) Prompt (with completion) for the
-name of a @TeX{} macro, and if @AUCTeX{} knows the macro, prompt for
-each argument.
-@end deffn
-
-As a default selection, @AUCTeX{} will suggest the macro last inserted
-or, as the first choice the value of the variable
-@code{TeX-default-macro}.
-
-@defopt TeX-default-macro
-Default macro to insert when invoking @code{TeX-insert-macro} first time.
-@end defopt
-
-@defopt TeX-insert-macro-default-style
-Specifies whether @code{TeX-insert-macro} will ask for all optional
-arguments.
-
-If set to the symbol @code{show-optional-args}, @code{TeX-insert-macro}
-asks for optional arguments of @TeX{} marcos, unless the previous
-optional argument has been rejected.  If set to
-@code{show-all-optional-args}, @code{TeX-insert-macro} asks for all
-optional arguments.  @code{mandatory-args-only}, @code{TeX-insert-macro}
-asks only for mandatory arguments.  When @code{TeX-insert-macro} is
-called with prefix argument (@kbd{C-u}), it's the other way round.
-@c FIXME: Now that the option has 3 candidates, it isn't clear what "the
-@c other way round" means.
-
-Note that for some macros, there are special mechanisms, e.g.@:
-@code{TeX-arg-cite-note-p} and @code{LaTeX-includegraphics-options-alist}.
-@end defopt
-
-
-A faster alternative is to enable the option
-@code{TeX-electric-escape}.
-
-@defopt TeX-electric-escape
-If this is non-nil, typing the @TeX{} escape character @kbd{\} will
-invoke the command @code{TeX-electric-macro}.
-
-In Texinfo mode, the command is invoked by @kbd{@@} instead.
-@end defopt
-
-The difference between @code{TeX-insert-macro} and
-@code{TeX-electric-macro} is that space key @key{SPC} will complete and exit from the
-minibuffer in @code{TeX-electric-macro}.  Use @key{TAB} if you merely
-want to complete.
-
-@deffn Command TeX-electric-macro
-Prompt (with completion) for the name of a @TeX{} macro,
-and if @AUCTeX{} knows the macro, prompt for each argument.
-Space (@key{SPC}) will complete and exit.
-@end deffn
-
-By default @AUCTeX{} will put an empty set braces @samp{@{@}} after a
-macro with no arguments to stop it from eating the next whitespace.
-This is suppressed inside math mode and can be disabled totally by
-setting @code{TeX-insert-braces} to nil.

-@defopt TeX-insert-braces
-If non-nil, append a empty pair of braces after inserting a macro with

-This variable is an alist.  Each element is a cons cell, whose car is
-the macro name, and the cdr is non-nil or nil, depending on whether a
-pair of braces should be, respectively, appended or not to the macro.

-If a macro has an element in this variable, @AUCTeX{} will
-use its value to decide what to do, whatever the value of the variable
-@code{TeX-insert-braces}.
-@end defopt
-
-Completions work because @AUCTeX{} can analyze @TeX{} files, and store
-symbols in Emacs Lisp files for later retrieval.  @xref{Automatic}, for

-@cindex Indenting
-@cindex Indentation
-@cindex Reformatting
-@cindex Reindenting
-
-Indentation means the addition of whitespace at the beginning of lines
-to reflect special syntactical constructs.  This makes it easier to see
-the structure of the document, and to catch errors such as a missing
-closing brace.  Thus, the indentation is done for precisely the same
-reasons that you would indent ordinary computer programs.
-
-Indentation is done by @LaTeX{} environments and by @TeX{} groups, that
-is the body of an environment is indented by the value of
-@code{LaTeX-indent-level} (default 2).  Also, items of an `itemize-like'
-environment are indented by the value of @code{LaTeX-item-indent},
-default @minus{}2.  (Items are identified with the help of
-@code{LaTeX-item-regexp}.)  If more environments are nested, they are
-indented `accumulated' just like most programming languages usually are
-seen indented in nested constructs.
-@vindex LaTeX-indent-level
-@vindex LaTeX-item-indent
-@vindex LaTeX-item-regexp
-
-You can explicitly indent single lines, usually by pressing @key{TAB},
-or marked regions by calling @code{indent-region} on it.  If you have
-@code{auto-fill-mode} enabled and a line is broken while you type it,
-Emacs automatically cares about the indentation in the following line.
-If you want to have a similar behavior upon typing @key{RET}, you can
-customize the variable @code{TeX-newline-function} and change the
-default of @code{newline} which does no indentation to
-@code{newline-and-indent} which indents the new line or
-@code{reindent-then-newline-and-indent} which indents both the current
-and the new line.
-@vindex TeX-newline-function
-@findex indent-region
-@cindex auto-fill-mode
-
-There are certain @LaTeX{} environments which should be indented in a
-special way, like @samp{tabular} or @samp{verbatim}.  Those environments
-may be specified in the variable @code{LaTeX-indent-environment-list}
-together with their special indentation functions.  Taking the
-@samp{verbatim} environment as an example you can see that
-@code{current-indentation} is used as the indentation function.  This
-will stop @AUCTeX{} from doing any indentation in the environment if you
-hit @key{TAB} for example.
-@vindex LaTeX-indent-environment-list
-
-There are environments in @code{LaTeX-indent-environment-list} which do
-not bring a special indentation function with them.  This is due to the
-fact that first the respective functions are not implemented yet and
-second that filling will be disabled for the specified environments.
-This shall prevent the source code from being messed up by accidently
-filling those environments with the standard filling routine.  If you
-think that providing special filling routines for such environments
-would be an appropriate and challenging task for you, you are invited to
-contribute.  (@xref{Filling}, for further information about the filling
-functionality.)
-@vindex LaTeX-indent-environment-list
-
-The check for the indentation function may be enabled or disabled by
-customizing the variable @code{LaTeX-indent-environment-check}.
-@vindex LaTeX-indent-environment-check
-
-For tabular-like environments, @AUCTeX{} has a built-in function to indent
-according to preceding @samp{&} signs and assigns it to all known
-tabular-like environments in the default value of
-@code{LaTeX-indent-environment-list}.
-
-@cindex align.el
-@findex align-current
-As a side note with regard to formatting special environments: Newer
-Emacsen include @file{align.el} and therefore provide some support for
-formatting @samp{tabular} and @samp{tabbing} environments with the
-function @code{align-current} which will nicely align columns in the
-source code.
-
-@AUCTeX{} is able to format commented parts of your code just as any
-other part.  This means @LaTeX{} environments and @TeX{} groups in
-comments will be indented syntactically correct if the variable
-@code{LaTeX-syntactic-comments} is set to t.  If you disable it,
-comments will be filled like normal text and no syntactic indentation
-will be done.
-@vindex LaTeX-syntactic-comments
-
-Following you will find a list of most commands and variables related
-to indenting with a small summary in each case:
-
-@table @kbd
-@item @key{TAB}
-@kindex @key{TAB}
-@findex LaTeX-indent-line
-@code{LaTeX-indent-line} will indent the current line.
-
-@item @key{LFD}
-@itemx C-j
-@kindex @key{LFD}
-@kindex C-j
-@code{newline-and-indent} inserts a new line (much like @key{RET}) and
-moves the cursor to an appropriate position by the left margin.
-
-Most keyboards nowadays lack a linefeed key and @kbd{C-j} may be tedious
-to type.  Therefore you can customize @AUCTeX{} to perform indentation
-upon typing @key{RET} as well.  The respective option is called
-@code{TeX-newline-function}.
-@end table
-
-@defopt LaTeX-indent-environment-list
-List of environments with special indentation.  The second element in
-each entry is the function to calculate the indentation level in
-columns.
-@end defopt
-
-@defopt LaTeX-indent-level
-Number of spaces to add to the indentation for each @samp{\begin} not
-matched by a @samp{\end}.
-@end defopt
-
-@defopt LaTeX-item-indent
-Number of spaces to add to the indentation for @samp{\item}'s in list
-environments.
-@end defopt
-
-@defopt TeX-brace-indent-level
-Number of spaces to add to the indentation for each @samp{@{} not
-matched by a @samp{@}}.
-@end defopt
-
-@defopt LaTeX-syntactic-comments
-If non-nil comments will be filled and indented according to @LaTeX{}
-syntax.  Otherwise they will be filled like normal text.
-@end defopt
-
-@defopt TeX-newline-function
-Used to specify the function which is called when @key{RET} is pressed.
-This will normally be @code{newline} which simply inserts a new line.
-In case you want to have @AUCTeX{} do indentation as well when you press
-@key{RET}, use the built-in functions @code{newline-and-indent} or
-@code{reindent-then-newline-and-indent}.  The former inserts a new line
-and indents the following line, i.e.@: it moves the cursor to the right
-position and therefore acts as if you pressed @key{LFD}.  The latter
-function additionally indents the current line.  If you choose
-@samp{Other}, you can specify your own fancy function to be called when
-@key{RET} is pressed.
-@end defopt
-
-@vindex LaTeX-begin-regexp
-@vindex LaTeX-end-regexp
-@AUCTeX{} treats by default @samp{\[...\]} math mode as a regular
-environment and indents it accordingly.  If you do not like such
-behavior you only need to remove @code{\|\[} and @code{\|\]} from
-@code{LaTeX-begin-regexp} and @code{LaTeX-end-regexp} variables
-respectively.
-
-A closely related topic is indenting of text enclosed in square brackets,
-parentheses and other pairs.  @AUCTeX{} offers two variables which control
-if indentation happens inside these pairs.
-
-@defopt TeX-indent-open-delimiters
-This variable contains additional opening delimiters which increase
-indentation.  For example add @code{[} to this variable to get text after
-a square bracket indented.
-@end defopt
-
-@defopt TeX-indent-close-delimiters
-This is the accompanying variable to @code{TeX-indent-open-delimiters}
-decreasing the indentation again.  This variable should contain @code{]}
-if @code{TeX-indent-open-delimiters} is set like described above.
-@end defopt
-
-@noindent
-Note that this is an opt-in feature, both variables are initially set to
-an empty string.  That is because it introduces non-trivial side effects
-to include @code{[} and @code{]} in @code{TeX-indent-open-delimiters} and
-@code{TeX-indent-close-delimiters}; if you only have an opening square
-bracket in your text without closing it, wrong indentation persists in the
-following text.  For example, in math expression, half-open intervals are
-frequently written as @samp{[0,10)} or @samp{[0,10[}.  In such cases, you
-can put the closing part as a comment in the same line in order to have
-correct indentation after that:
-@example
-$[0,10)$ % ]
-$[0,10[$ % ]]
-@end example
-
-Another example is @samp{\left}-@samp{\right} pair in equations.  Similar
-workarounds are available:
-@example
-\begin@{equation@}
-  \left[ % ]
-    xyz
-  \right] % [
-  abc
-\end@{equation@}
-@end example
-
-You can include parens @samp{()} also in @code{TeX-indent-open-delimiters}
-and @code{TeX-indent-close-delimiters} to enable indent inside them.  Be
-prepared for similar side effects when you do.
-
-Note that commented curly braces @code{@{} and @code{@}} aren't counted
-when @AUCTeX{} computes indentation.

-@cindex Filling
-@cindex Formatting
-@cindex Reformatting
-@cindex Refilling
-@findex auto-fill-mode
-@findex turn-on-auto-fill
-@vindex fill-column
-
-Filling deals with the insertion of line breaks to prevent lines from
-becoming wider than what is specified in @code{fill-column}.  The
-linebreaks will be inserted automatically if @code{auto-fill-mode} is
-enabled.  In this case the source is not only filled but also indented
-automatically as you write it.
-
-@code{auto-fill-mode} can be enabled for @AUCTeX{} by calling
-@code{turn-on-auto-fill} in one of the hooks @AUCTeX{} is running.
-@xref{Modes and Hooks}.  As an example, if you want to enable
-@code{auto-fill-mode} in @code{LaTeX-mode}, put the following into your
-init file:
-
-@lisp
-(add-hook 'LaTeX-mode-hook #'turn-on-auto-fill)
-@end lisp
-
-You can manually fill explicitly marked regions, paragraphs,
-environments, complete sections, or the whole buffer.  (Note that manual
-filling in @AUCTeX{} will indent the start of the region to be filled in
-contrast to many other Emacs modes.)
-
-There are some syntactical constructs which are handled specially with
-regard to filling.  These are so-called @dfn{code comments} and
-@dfn{paragraph commands}.
-
-Code comments are comments preceded by code or text in the same line.
-Upon filling a region, code comments themselves will not get filled.
-Filling is done from the start of the region to the line with the code
-comment and continues after it.  In order to prevent overfull lines in
-the source code, a linebreak will be inserted before the last
-non-comment word by default.  This can be changed by customizing
-@code{LaTeX-fill-break-before-code-comments}.  If you have overfull
-lines with code comments you can fill those explicitly by calling
-@code{LaTeX-fill-paragraph} or pressing @kbd{M-q} with the cursor
-positioned on them.  This will add linebreaks in the comment and indent
-subsequent comment lines to the column of the comment in the first line
-of the code comment.  In this special case @kbd{M-q} only acts on the
-current line and not on the whole paragraph.
-
-Lines with @samp{\par} are treated similarly to code comments,
-i.e.@: @samp{\par} will be treated as paragraph boundary which should not
-be followed by other code or text.  But it is not treated as a real
-paragraph boundary like an empty line where filling a paragraph would
-stop.
-
-Paragraph commands like @samp{\section} or @samp{\noindent} (the list of
-commands is defined by @code{LaTeX-paragraph-commands}) are often to be
-placed in their own line(s).  This means they should not be consecuted
-with any preceding or following adjacent lines of text.  @AUCTeX{} will
-prevent this from happening if you do not put any text except another
-macro after the end of the last brace of the respective macro.  If
-there is other text after the macro, @AUCTeX{} regards this as a sign
-that the macro is part of the following paragraph.
-@vindex LaTeX-paragraph-commands
-
-Here are some examples:
-
-@example
-\begin@{quote@}
-  text text text text
-@end example
-
-@example
-\begin@{quote@}\label@{foo@}
-  text text text text
-@end example
-
-If you press @kbd{M-q} on the first line in both examples, nothing will
-change.  But if you write
-
-@example
-\begin@{quote@} text
-  text text text text
-@end example
-@noindent
-and press @kbd{M-q}, you will get
-
-@example
-\begin@{quote@} text text text text text
-@end example
-
-Besides code comments and paragraph commands, another speciality of
-filling in @AUCTeX{} involves commented lines.  You should be aware that
-these comments are treated as islands in the rest of the @LaTeX{} code
-if syntactic filling is enabled.  This means, for example, if you try to
-fill an environment with @code{LaTeX-fill-environment} and have the
-cursor placed on a commented line which does not have a surrounding
-environment inside the comment, @AUCTeX{} will report an error.
-@findex LaTeX-fill-environment

-
-@table @kbd
-@item C-c C-q C-p

-@defopt LaTeX-fill-break-before-code-comments

-It is often desirable to get visual help of what markup code in a text
-actually does without having to decipher it explicitly.  For this
-purpose Emacs and @AUCTeX{} provide font locking (also known as syntax
-highlighting) which visually sets off markup code like macros or
-environments by using different colors or fonts.  For example text to be
-typeset in italics can be displayed with an italic font in the editor as
-well, or labels and references get their own distinct color.
-
-While font locking helps you grasp the purpose of markup code and
-separate markup from content, the markup code can still be distracting.
-@AUCTeX{} lets you hide those parts and show them again at request with
-its built-in support for hiding macros and environments which we call
-folding here.
-
-Besides folding of macros and environments, @AUCTeX{} provides support
-for Emacs' outline mode which lets you narrow the buffer content to
-certain sections of your text by hiding the parts not belonging to these
-sections.
-
-Moreover, you can focus in a specific portion of the code by narrowing
-the buffer to the desired region.  @AUCTeX{} provides also functions to
-narrow the buffer to the current group and to @LaTeX{} environments.
-
-@AUCTeX{} also provides some WYSIWYG features.
-
-First, you can customize @code{font-latex-fontify-script} to enable
-special formatting of @code{^} superscripts and @code{_} subscripts
-(@pxref{Font Locking}).
-
-Secondly, @AUCTeX{} with GNU Emacs 25 or later can display certain math
-macros using Unicode characters, e.g., @code{\alpha} as α.  This is
-called prettification and is lightweight and reasonable robust
-(@pxref{Prettifying}).
-
-A more accurate approach is provided by @previewlatex{}, a subsystem of
-@AUCTeX{}, see @ref{Top,,Introduction,preview-latex,The @previewlatex{}
-Manual}.  This system uses @LaTeX{} to generate images that are then
-displayed in your buffer.  It is extremely accurate but can be fragile
-with some packages (like older pgf versions).
-
-Please note that you can use prettification and @previewlatex{} together.

-Font locking is supposed to improve readability of the source code by
-highlighting certain keywords with different colors or fonts.  It
-thereby lets you recognize the function of markup code to a certain
-extent without having to read the markup command.  For general
-information on controlling font locking with Emacs' Font Lock mode, see
-@ref{Font Lock, , Font Lock Mode, emacs, GNU Emacs Manual}.
-
-@defopt TeX-install-font-lock
-Once font locking is enabled globally or for the major modes provided by
-@AUCTeX{}, the font locking patterns and functionality of @fontlatex{}
-are activated by default.  You can switch to a different font locking
-scheme or disable font locking in @AUCTeX{} by customizing the variable
-@code{TeX-install-font-lock}.
-
-Besides @fontlatex{} @AUCTeX{} ships with a scheme which is derived
-from Emacs' default @LaTeX{} mode and activated by choosing
-@code{tex-font-setup}.  Be aware that this scheme is not coupled with
-@AUCTeX{}'s style system and not the focus of development.  Therefore
-and due to @fontlatex{} being much more feature-rich the following
-explanations will only cover @fontlatex{}.
-
-In case you want to hook in your own fontification scheme, you can

-@node Fontification of macros
-@subsection Fontification of macros
-
-Highlighting of macros can be customized by adapting keyword lists which
-can be found in the customization group @code{font-latex-keywords}.
-
-Three types of macros can be handled differently with respect to
-fontification:
-
-@enumerate
-@item
-Commands of the form @samp{\foo[bar]@{baz@}} which consist of the macro
-itself, optional arguments in square brackets and mandatory arguments in
-curly braces.  For the command itself the face
-@code{font-lock-keyword-face} will be used and for the optional
-arguments the face @code{font-lock-variable-name-face}.  The face
-applied to the mandatory argument depends on the macro class represented
-by the respective built-in variables.
-@item
-Declaration macros of the form @samp{@{\foo text@}} which consist of the
-macro which may be enclosed in a @TeX{} group together with text to be
-affected by the macro.  In case a @TeX{} group is present, the macro
-will get the face @code{font-lock-keyword-face} and the text will get
-the face configured for the respective macro class.  If no @TeX{} group
-is present, the latter face will be applied to the macro itself.
-@item
-Simple macros of the form @samp{\foo} which do not have any arguments or
-groupings.  The respective face will be applied to the macro itself.
-@end enumerate
-
-Customization variables for @samp{\foo[bar]@{baz@}} type macros allow
-both the macro name and the sequence of arguments to be specified.  The
-latter is done with a string which can contain the characters
-@table @samp
-@item *
-indicating the existence of a starred variant for the macro,
-@item [
-for optional arguments in brackets,
-@item @{
-for mandatory arguments in braces,
-@item \
-for mandatory arguments consisting of a single macro and
-@item |
-as a prefix indicating that two alternatives are following.
-@end table
-For example the specifier for @samp{\documentclass} would be @samp{[@{}
-because the macro has one optional followed by one mandatory argument.
-The specifier for @samp{\newcommand} would be @samp{*|@{\[[@{} because
-there is a starred variant, the mandatory argument following the macro
-name can be a macro or a @TeX{} group which can be followed by two
-optional arguments and the last token is a mandatory argument in braces.
-
-Customization variables for the @samp{@{\foo text@}} and @samp{\foo}
-types are simple lists of strings where each entry is a macro name
-(without the leading backslash).
-
-@subheading General macro classes
-
-@fontlatex{} provides keyword lists for different macro classes which
-are described in the following table:
-
-@vindex font-latex-match-function-keywords
-@vindex font-latex-match-reference-keywords
-@vindex font-latex-match-textual-keywords
-@vindex font-latex-match-variable-keywords

-@end table
-
-@subheading Sectioning commands
-@cindex Sectioning commands, fontification of
-
-Sectioning commands are macros like @samp{\chapter} or @samp{\section}.
-For these commands there are two fontification schemes which may be
-selected by customizing the variable @code{font-latex-fontify-sectioning}.
-
-@defopt font-latex-fontify-sectioning
-@c FIXME: Is @vindex correct?
-@vindex font-latex-sectioning-0-face
-@vindex font-latex-sectioning-1-face
-@vindex font-latex-sectioning-2-face
-@vindex font-latex-sectioning-3-face
-@vindex font-latex-sectioning-4-face
-@vindex font-latex-sectioning-5-face
-Per default sectioning commands will be shown in a larger, proportional
-font, which corresponds to a number for this variable.  The font size
-varies with the sectioning level, e.g.@: @samp{\part}
-(@code{font-latex-sectioning-0-face}) has a larger font than
-@samp{\paragraph} (@code{font-latex-sectioning-5-face}).  Typically,
-values from 1.05 to 1.3 for @code{font-latex-fontify-sectioning} give
-best results, depending on your font setup.  If you rather like to use
-the base font and a different color, set the variable to the symbol
-@samp{color}.  In this case the face @code{font-lock-type-face} will be
-used to fontify the argument of the sectioning commands.
-@end defopt
-
-@vindex font-latex-match-sectioning-0-keywords
-@vindex font-latex-match-sectioning-1-keywords
-@vindex font-latex-match-sectioning-2-keywords
-@vindex font-latex-match-sectioning-3-keywords
-@vindex font-latex-match-sectioning-4-keywords
-@vindex font-latex-match-sectioning-5-keywords
-You can make @fontlatex{} aware of your own sectioning commands be
-adding them to the keyword lists:
-@code{font-latex-match-sectioning-0-keywords}
-(@code{font-latex-sectioning-0-face}) @dots{}
-@code{font-latex-match-sectioning-5-keywords}
-(@code{font-latex-sectioning-5-face}).
-
-@vindex font-latex-slide-title-face
-@vindex font-latex-match-slide-title-keywords
-Related to sectioning there is special support for slide titles which
-may be fontified with the face @code{font-latex-slide-title-face}.  You
-can add macros which should appear in this face by customizing the
-variable @code{font-latex-match-slide-title-keywords}.
-
-@subheading Commands for changing fonts
-
-@LaTeX{} provides various macros for changing fonts or font attributes.
-For example, you can select an italic font with @samp{\textit@{...@}} or
-bold with @samp{\textbf@{...@}}.  An alternative way to specify these
-fonts is to use special macros in @TeX{} groups, like @samp{@{\itshape
-...@}} for italics and @samp{@{\bfseries ...@}} for bold.  As mentioned
-above, we call the former variants commands and the latter
-declarations.
-
-Besides the macros for changing fonts provided by @LaTeX{} there is an
-infinite number of other macros---either defined by yourself for logical
-markup or defined by macro packages---which affect the font in the
-typeset text.  While @LaTeX{}'s built-in macros and macros of packages
-known by @AUCTeX{} are already handled by @fontlatex{}, different
-keyword lists per type style and macro type are provided for entering
-your own macros which are listed in the table below.
-
-@vindex font-latex-match-bold-command-keywords
-@vindex font-latex-match-italic-command-keywords
-@vindex font-latex-match-math-command-keywords

-
-@subheading Deactivating defaults of built-in keyword classes
-
-@vindex font-latex-deactivated-keyword-classes
-@fontlatex{} ships with predefined lists of keywords for the classes
-described above.  You can disable these defaults per class by
-customizing the variable @code{font-latex-deactivated-keyword-classes}.
-This is a list of strings for keyword classes to be deactivated.  Valid
-entries are "warning", "variable", "biblatexnoarg", "biblatex",
-"reference", "function" , "sectioning-0", "sectioning-1",
-"sectioning-2", "sectioning-3", "sectioning-4", "sectioning-5",
-"slide-title", "textual", "bold-command", "italic-command",
-"math-command", "type-command", "bold-declaration",
-"italic-declaration", "type-declaration".
-
-You can also get rid of certain keywords only.  For example if you want
-to remove highlighting of footnotes as references you can put the
-following stanza into your init file:
-
-@lisp
-(eval-after-load "font-latex"
-  '(setq-default
-    font-latex-match-reference-keywords-local
-    (remove (assoc-string "footnote"
-            font-latex-match-reference-keywords-local)
-                font-latex-match-reference-keywords-local)))
-@end lisp
-
-But note that this means fiddling with @fontlatex{}'s internals and is
-not guaranteed to work in future versions of @fontlatex{}.
-
-@subheading User-defined keyword classes
-
-In case the customization options explained above do not suffice for
-your needs, you can specify your own keyword classes by customizing the
-variable @code{font-latex-user-keyword-classes}.
-
-@defopt font-latex-user-keyword-classes
-Every keyword class consists of four parts, a name, a list of keywords,
-a face and a specifier for the type of macros to be highlighted.
-
-When adding new entries, you have to use unique values for the class
-names, i.e.@: they must not clash with names of the built-in keyword
-classes or other names given by you.  Additionally the names must not
-contain spaces.
-
-The list of keywords defines which commands and declarations should be
-covered by the keyword class.  A keyword can either be a simple command
-name omitting the leading backslash or a list consisting of the command
-name and a string specifying the sequence of arguments for the command.
-
-The face argument can either be an existing face or face attributes
-made by you.
-
-There are three alternatives for the type of keywords---``Command with
-arguments'', ``Declaration inside @TeX{} group'' and ``Command without
-arguments''---which correspond with the macro types explained above.

-@node Fontification of quotes
-@subsection Fontification of quotes
-@cindex Quotes, fontification of
-
-Text in quotation marks is displayed with the face
-@code{font-latex-string-face}.  Besides the various forms of opening and
-closing double and single quotation marks, so-called guillemets (<<, >>)
-can be used for quoting.  Because there are two styles of using
-them---French style: << text >>; German style: >>text<<---you can
-customize the variable @code{font-latex-quotes} to tell @fontlatex{}
-which type you are using if the correct value cannot be derived from
-document properties.
-
-@defopt font-latex-quotes
-The default value of @code{font-latex-quotes} is @samp{auto} which means
-that @fontlatex{} will try to derive the correct type of quotation mark
-matching from document properties like the language option supplied to
-the babel @LaTeX{} package.
-
-If the automatic detection fails for you and you mostly use one specific
-style you can set it to a specific language-dependent value as well.
-Set the value to @samp{german} if you are using >>German quotes<< and to
-@samp{french} if you are using << French quotes >>.  @fontlatex{} will
-recognize the different ways these quotes can be given in your source
-code, i.e.@: (@samp{"<}, @samp{">}), (@samp{<<}, @samp{>>}) and the
-respective 8-bit variants.
-
-If you set @code{font-latex-quotes} to nil, quoted content will not be
-fontified.

-@vindex texmathp-tex-commands-default
-In @LaTeX{} mathematics can be indicated by a variety of different
-methods: toggles (like dollar signs), macros and environments.  Math
-constructs known by @fontlatex{} are displayed with the face
-@code{font-latex-math-face}.  Support for dollar signs and shorthands
-like @samp{\(...\)} or @samp{\[...\]} is built-in and not customizable.
-Support for other math macros and environments can be adapted by
-customizing the variables @code{font-latex-match-math-command-keywords}
-and @code{texmathp-tex-commands} respectively.  It is no longer
-recommended to customize @code{font-latex-math-environments}.
-
-To convert your customization in @code{font-latex-math-environments}
-into @code{texmathp-tex-commands}, please register your own math
-environments, together with starred variants if any, as entries of
-@code{env-on} type in @code{texmathp-tex-commands}, then clear out
-@code{font-latex-math-environments}.  You have to restart Emacs for this
-new customization to take effect for fontification.
-
-In order to make math constructs more readable, @fontlatex{} displays
-subscript and superscript parts in a smaller font and raised or lowered
-respectively.  This fontification feature can be controlled with the
-variables @code{font-latex-fontify-script} and
-@code{font-latex-script-display}.
-
-@defopt font-latex-fontify-script
-If non-nil, fontify subscript and superscript strings.  Concretely, this
-means that the scripts are raised or lowered.
-
-Another possiblity is setting this variable to the symbol
-@code{multi-level}.  In this case, in a formula @i{x^@{y^z@}}, @i{y} is
-raised above and smaller than @i{x}, and @i{z} is raised above and
-smaller than @i{y}.  With many script levels, the text might become too
-small to be readable.  (See @code{font-latex-fontify-script-max-level}
-below.)
-
-Lastly, you can set this variable to @code{invisible} whose behavior is
-like @code{multi-level}, and in addition the super-/subscript characters
-@i{^} and @i{_} are not displayed.

-@vindex font-latex-superscript-face
-@vindex font-latex-subscript-face

-Maximum scriptification level for which script faces are applied.
-
-The faces @code{font-latex-superscript-face} and
-@code{font-latex-subscript-face} define custom @code{:height} values <
-1.0.  Therefore, scripts are displayed with a slightly smaller font than
-normal math text.  If @code{font-latex-fontify-script} is
-@code{multi-level} or @code{invisible}, the font size becomes too small
-to be readable after a few levels.  This option allows to specify the
-maximum level after which the size of the script text won’t be shrunken
-anymore.
-
-For example, in the expression @i{x^@{y^@{z^a_b@}@}}, @i{x} has
-scriptification level 0, @i{y} has level 1, @i{z} has level 2, and both
-@i{a} and @i{b} have scriptification level 3.
-
-If @code{font-latex-fontify-script-max-level} was 2, then @i{z}, @i{a},
-and @i{b} would have the same font size.  If it was 3 or more, then
-@i{a} and @i{b} were smaller than @i{z} just in the same way as @i{z} is
-smaller than @i{y} and @i{y} is smaller than @i{x}.

-
-In certain cases the fontification machinery fails to interpret buffer
-contents correctly.  This can lead to color bleed, i.e.@: large parts of a
-buffer get fontified with an inappropriate face.  A typical situation
-for this to happen is the use of a dollar sign (@samp{$}) in a verbatim
-macro or environment.  If @fontlatex{} is not aware of the verbatim
-construct, it assumes the dollar sign to be a toggle for mathematics and
-fontifies the following buffer content with the respective face until it
-finds a closing dollar sign or till the end of the buffer.
-
-As a remedy you can make the verbatim construct known to @fontlatex{}
-(@pxref{Verbatim content}).  If this is not possible, you can insert a

-@node Folding
-@section Folding Macros and Environments
-@cindex Outlining
-@cindex Folding
-@cindex Reveal
-@cindex Auto-Reveal
-@cindex Hide Macros
-
-A popular complaint about markup languages like @TeX{} and @LaTeX{} is
-that there is too much clutter in the source text and that one cannot
-focus well on the content.  There are macros where you are only
-interested in the content they are enclosing, like font specifiers where
-the content might already be fontified in a special way by font locking.
-Or macros the content of which you only want to see when actually
-editing it, like footnotes or citations.  Similarly you might find
-certain environments or comments distracting when trying to concentrate
-on the body of your document.
-
-With @AUCTeX{}'s folding functionality you can collapse those items and
-replace them by a fixed string, the content of one of their arguments,
-or a mixture of both.  If you want to make the original text visible
-again in order to view or edit it, move point sideways onto the
-placeholder (also called display string) or left-click with the mouse
-pointer on it.  The
-macro or environment will unfold automatically, stay open as long as
-point is inside of it and collapse again once you move point out of it.
-(Note that folding of environments currently does not work in every
-@AUCTeX{} mode.)
-
-In order to use this feature, you have to activate @code{TeX-fold-mode}
-which will activate the auto-reveal feature and the necessary commands
-to hide and show macros and environments.  You can activate the mode in
-a certain buffer by typing the command @kbd{M-x TeX-fold-mode @key{RET}} or
-using the keyboard shortcut @kbd{C-c C-o C-f}.  If you want to use it
-every time you edit a @LaTeX{} document, add it to a hook:
-@findex TeX-fold-mode
-@kindex C-c C-o C-f
-
-@lisp
-(add-hook 'LaTeX-mode-hook (lambda ()
-                             (TeX-fold-mode 1)))
-@end lisp
-
-If it should be activated in all @AUCTeX{} modes, use
-@code{TeX-mode-hook} instead of @code{LaTeX-mode-hook}.
-
-Once the mode is active there are several commands available to hide
-and show macros, environments and comments:
-
-@deffn Command TeX-fold-buffer
-@kindex C-c C-o C-b
-(@kbd{C-c C-o C-b}) Hide all foldable items in the current buffer
-according to the setting of @code{TeX-fold-type-list}.
-
-If you want to have this done automatically every time you open a file,
-add it to a hook and make sure the function is called after font locking
-is set up for the buffer.  The following code should accomplish this:
-
-@lisp
-(add-hook 'find-file-hook #'TeX-fold-buffer t)
-@end lisp
-
-The command can be used any time to refresh the whole buffer and fold
-any new macros and environments which were inserted after the last
-invocation of the command.
-@end deffn
-
-@defopt TeX-fold-type-list
-List of symbols determining the item classes to consider for folding.
-This can be macros, environments and comments.  Per default only macros
-and environments are folded.
-@end defopt
-
-@defopt TeX-fold-force-fontify
-In order for all folded content to get the right faces, the whole buffer
-has to be fontified before folding is carried out.
-@code{TeX-fold-buffer} therefore will force fontification of unfontified
-regions.  As this will prolong the time folding takes, you can prevent
-forced fontification by customizing the variable
-@code{TeX-fold-force-fontify}.
-@end defopt
-
-@defopt TeX-fold-auto
-By default, a macro inserted with @code{TeX-insert-macro} (@kbd{C-c

-aumatically fold macros as soon as they are inserted.
-@end defopt
-
-@defopt TeX-fold-preserve-comments
-By default items found in comments will be folded.  If your comments
-often contain unfinished code this might lead to problems.  Give this
-variable a non-nil value and foldable items in your comments will be
-left alone.
-@end defopt
-

-@kindex C-c C-o C-o
-(@kbd{C-c C-o C-o}) Hide or show items according to the current context.

-The commands above will only take macros or environments into
-consideration which are specified in the variables
-@code{TeX-fold-macro-spec-list} or @code{TeX-fold-env-spec-list}
-respectively.
-
-@defopt TeX-fold-macro-spec-list
-List of replacement specifiers and macros to fold.  The specifier can be
-a string, an integer or a function symbol.
-
-If you specify a string, it will be used as a display replacement for
-the whole macro.  Numbers in braces, brackets, parens or angle brackets
-will be replaced by the respective macro argument.  For example
-@samp{@{1@}} will be replaced by the first mandatory argument of the
-macro.  One can also define alternatives within the specifier which are
-used if an argument is not found.  Alternatives are separated by
-@samp{||}.  They are most useful with optional arguments.  As an
-example, the default specifier for @samp{\item} is @samp{[1]:||*} which
-means that if there is an optional argument, its value is shown followed
-by a colon.  If there is no optional argument, only an asterisk is used
-as the display string.
-
-If you specify a number as the first element, the content of the
-respective mandatory argument of a @LaTeX{} macro will be used as the
-placeholder.
-
-If the first element is a function symbol, the function will be called
-with all mandatory arguments of the macro and the result of the function
-call will be used as a replacement for the macro.
-
-The placeholder is made by copying the text from the buffer together with
-its properties, i.e.@: its face as well.  If fontification has not
-happened when this is done (e.g.@: because of lazy font locking) the
-intended fontification will not show up.  As a workaround you can leave
-Emacs idle a few seconds and wait for stealth font locking to finish
-before you fold the buffer.  Or you just re-fold the buffer with
-@code{TeX-fold-buffer} when you notice a wrong fontification.
-@end defopt
-
-@defopt TeX-fold-env-spec-list
-List of display strings or argument numbers and environments to fold.
-Argument numbers refer to the @samp{\begin} statement.  That means if
-you have e.g.@: @samp{\begin@{tabularx@}@{\linewidth@}@{XXX@} ...
-\end@{tabularx@}} and specify 3 as the argument number, the resulting
-display string will be ``XXX''.

-@vindex LaTeX-fold-math-spec-list
-The variables @code{TeX-fold-macro-spec-list},
-@code{TeX-fold-env-spec-list}, and @code{TeX-fold-math-spec-list} apply
-to any @AUCTeX{} mode.  If you want to make settings which are only
-applied to @LaTeX{} mode, you can use the mode-specific variables
-@code{LaTeX-fold-macro-spec-list}, @code{LaTeX-fold-env-spec-list}, and
-@code{LaTeX-fold-math-spec-list}
-

-@end defopt
-
-@defopt TeX-fold-unspec-use-name
-If non-nil the name of the macro or environment surrounded by square
-brackets is used as display string, otherwise the defaults specified in
-@code{TeX-fold-unspec-macro-display-string} or
-@code{TeX-fold-unspec-env-display-string} respectively.
-@end defopt
-
-When you hover with the mouse pointer over folded content, its original
-text will be shown in a tooltip or the echo area depending on Tooltip
-mode being activate.  In order to avoid exorbitantly big tooltips and to
-cater for the limited space in the echo area the content will be cropped
-after a certain amount of characters defined by the variable
-@code{TeX-fold-help-echo-max-length}.

-
-You can add your own headings by setting the variable

-
-@defvar TeX-outline-extra
-List of extra @TeX{} outline levels.
-
-Each element is a list with two entries.  The first entry is the regular

-@node Narrowing
-@section Narrowing
-
-Sometimes you want to focus your attention to a limited region of the
-code.  You can do that by restricting the text addressable by editing
-commands and hiding the rest of the buffer with the narrowing functions,
-@pxref{Narrowing,,,emacs,GNU Emacs Manual}.  In addition, @AUCTeX{}
-provides a couple of other commands to narrow the buffer to a group,
-i.e.@: a region enclosed in a pair of curly braces, and to @LaTeX{}
-environments.
-
-@deffn Command TeX-narrow-to-group
-@kindex C-x n g

-(@kbd{C-x n e}) Make text outside current environment invisible.  With
-optional argument @var{count} keep visible that number of enclosing
-environmens.
-@end deffn

-@node Prettifying
-@section Prettifying
-
-Emacs 25 is able to prettify symbols in programming language buffers,
-@pxref{Misc for Programs,,,emacs,GNU Emacs Manual}.  The canonical
-example is to display @code{(lambda () ...)} as @code{(λ () ...)} in
-Lisp buffers.
-
-@AUCTeX{} can use this feature in order to display certain math macros
-and greek letters using their Unicode representation, too.  For example,
-the @TeX{} code @code{\alpha \times \beta} will be displayed as @code{α
-× β}.  When point is on one of the characters, it'll be unprettified
-automatically, meaning you see the verbatim text again.  For this
-behaviour however you need to set
-@code{prettify-symbols-unprettify-at-point} to t or @code{right-edge}
-which will unprettify the symbol when point moves into or near it.
-
-To enable prettification in @AUCTeX{}, simply add
-@code{prettify-symbols-mode} to @code{TeX-mode-hook}.  If you enabled
-prettification globally with @code{global-prettify-symbols-mode}, then
-it's automatically enabled in @AUCTeX{}, too.
-
-You can also add custom symbol unicode-character pairs for
-prettification by adding to @code{tex--prettify-symbols-alist}.  Note
-that this variable is part of Emacs' stock @code{tex-mode.el} and used
-by that and @AUCTeX{}.

-
-There are two ways to run an external command, you can either run it on
-the current document with @code{TeX-command-master}, or on the current
-region with @code{TeX-command-region}.  A special case of running @TeX{}
-on a region is @code{TeX-command-buffer} which differs from
-@code{TeX-command-master} if the current buffer is not its own master
-file.
-
-@deffn Command TeX-command-master
-@kindex C-c C-c
-(@kbd{C-c C-c})  Query the user for a command, and run it on the master
-file associated with the current buffer.  The name of the master file is

-controlled by the variable @code{TeX-command-list}.
-@vindex TeX-master
-@vindex TeX-command-list
-@end deffn
-
-@deffn Command TeX-command-region
-@kindex C-c C-r
-(@kbd{C-c C-r}) Query the user for a command, and run it on the contents
-of the selected region.  The region contents are written into the region
-file, after extracting the header and trailer from the master file.  If
-mark is inactive (which can happen with Transient Mark mode), use the
-old region.  See also the command @code{TeX-pin-region} about how to fix
-a region.
-
-The name of the region file is controlled by the variable
-@code{TeX-region}.  The name of the master file is controlled by the
-variable @code{TeX-master}.  The header is all text up to the line
-matching the regular expression @code{TeX-header-end}.  The trailer is
-all text from the line matching the regular expression
-@code{TeX-trailer-start}.  The available commands are controlled by the
-variable @code{TeX-command-list}.

-
-@deffn Command TeX-command-buffer
-@kindex C-c C-b
-(@kbd{C-c C-b}) Query the user for a command, and apply it to the
-contents of the current buffer.  The buffer contents are written into
-the region file, after extracting the header and trailer from the master
-file.  The command is then actually run on the region file.  See above
-for details.
-@end deffn
-
-@deffn Command LaTeX-command-section
-@kindex C-c C-z
-(@kbd{C-c C-z}) Query the user for a command, and apply it to the
-current section (or part, chapter, subsection, paragraph, or
-subparagraph).  What makes the current section is determined by
-@code{LaTeX-command-section-level} which can be enlarged/shrunken using
-@code{LaTeX-command-section-change-level} (@kbd{C-c M-z}).  The given
-numeric prefix arg is added to the current value of
-@code{LaTeX-command-section-level}.  By default,
-@code{LaTeX-command-section-level} is initialized with the current
-document's @code{LaTeX-largest-level}.  The buffer contents are written
-into the region file, after extracting the header and trailer from the
-master file.  The command is then actually run on the region file.  See
-@code{TeX-command-region} for details.
-@end deffn
-
-It is also possible to compile automatically the whole document until it
-is ready with a single command: @code{TeX-command-run-all}.
-
-@deffn Command TeX-command-run-all

-(@kbd{C-c C-a}) Compile the current document until an error occurs or it
-is finished.  If compilation finishes successfully, run the viewer at
-the end.
-@end deffn
-
-Here are some relevant variables.
-
-@defopt TeX-region
-The name of the file for temporarily storing the text when formatting
-the current region.
-@end defopt
-
-@defopt TeX-header-end
-A regular expression matching the end of the header.  By default, this
-is @samp{\begin@{document@}} in @LaTeX{} mode and @samp{%**end of
-header} in plain @TeX{} mode.
-@end defopt
-
-@defopt TeX-trailer-start
-A regular expression matching the start of the trailer.  By default,
-this is @samp{\end@{document@}} in @LaTeX{} mode and @samp{\bye} in
-plain @TeX{} mode.
-@end defopt
-
-If you want to change the values of @code{TeX-header-end} and
-@code{TeX-trailer-start} you can do this for all files by setting the
-variables in a mode hook or per file by specifying them as file
-variables (@pxref{File Variables,,,emacs,The Emacs Editor}).
-
-@deffn Command TeX-pin-region
-@kindex C-c C-t C-r
-(@kbd{C-c C-t C-r}) If you don't have a mode like Transient Mark mode
-active, where marks get disabled automatically, the region would need to
-get properly set before each call to @code{TeX-command-region}.  If you
-fix the current region with @kbd{C-c C-t C-r}, then it will get used for
-more commands even though mark and point may change.  An explicitly
-activated mark, however, will always define a new region when calling
-@code{TeX-command-region}.
-@end deffn
-
-If the last process you started was
-on the region, the commands described in @ref{Debugging} and
-@ref{Control} will work on that process, otherwise they will work on the
-process associated with the current document.
-
-Don't run more than one process at the same time.  @AUCTeX{} doesn't
-support simultaneous typeset including region typeset.  Wait for the
-previous process to finish before you start a new process, in particular
-when you are editing multiple documents in parallel.  This limitation
-applies for preview by @previewlatex{} as well.
-
-@node Selecting a Command
-@subsection Selecting and Executing a Command
-
-Once you started the command selection with @kbd{C-c C-c}, @kbd{C-c C-r}
-or @kbd{C-c C-b} you will be prompted for the type of command.
-@AUCTeX{} will try to guess which command is appropriate in the given
-situation and propose it as default.  Usually this is a processor like
-@samp{TeX} or @samp{LaTeX} if the document was changed or a viewer if
-the document was just typeset.  Other commands can be selected in the
-minibuffer with completion support by typing @key{TAB}.
-
-@vindex TeX-command-list
-@vindex TeX-expand-list
-The available commands are defined by the variable
-@code{TeX-command-list}.  Per default it includes commands for
-typesetting the document (e.g.@: @samp{LaTeX}), for viewing the output
-(@samp{View}), for printing (@samp{Print}), for generating an index
-(@samp{Index}) or for spell checking (@samp{Spell}) to name but a few.
-You can also add your own commands by adding entries to
-@code{TeX-command-list}.  Refer to its doc string for information about
-its syntax.  You might also want to look at @code{TeX-expand-list} to
-learn about the expanders you can use in @code{TeX-command-list}.
-
-Note that the default of the variable occasionally changes.  Therefore
-it is advisable to add to the list rather than overwriting it.  You can
-do this with a call to @code{add-to-list} in your init file.  For
-example, if you wanted to add a command for running a program called
-@samp{foo} on the master or region file, you could do this with the
-following form.
-
-@lisp
-(eval-after-load "tex"
-  '(add-to-list 'TeX-command-list
-                '("Foo" "foo %s" TeX-run-command t t :help "Run foo")
-                t))
-@end lisp
-
-As mentioned before, @AUCTeX{} will try to guess what command you want
-to invoke.  If you want to use another command than @samp{TeX},
-@samp{LaTeX} or whatever processor @AUCTeX{} thinks is appropriate for
-the current mode, set the variable @code{TeX-command-default}.  You can
-do this for all files by setting it in a mode hook or per file by
-specifying it as a file variable (@pxref{File Variables,,,emacs,The
-Emacs Editor}).
-
-@defopt TeX-command-default
-The default command to run in this buffer.  Must be an entry in
-@code{TeX-command-list}.
-@end defopt
-
-@cindex Biber
-@cindex biblatex
-In case you use biblatex in a document, when automatic parsing is
-enabled @AUCTeX{} checks the value of @samp{backend} option given to
-biblatex at load time to decide whether to use Bib@TeX{} or Biber for
-bibliography processing.  Should @AUCTeX{} fail to detect the right
-backend, you can use the file local @code{LaTeX-biblatex-use-Biber}
-variable.
-@defvr Variable LaTeX-biblatex-use-Biber
-If this boolean variable is set as file local, it tells to @AUCTeX{}
-whether to use Biber with biblatex.  In this case, the autodetection of
-the biblatex backend will be overridden.  You may want to set locally
-this variable if automatic parsing is not enabled.
-@end defvr
-
-After confirming a command to execute, @AUCTeX{} will try to save any
-buffers related to the document, and check if the document needs to be
-reformatted.  If the variable @code{TeX-save-query} is non-nil,
-@AUCTeX{} will query before saving each file.  By default @AUCTeX{} will
-check emacs buffers associated with files in the current directory, in

-
-@cindex ispell
-When performing spell checking on a document or a region (invoked
-through @AUCTeX{}'s @samp{Spell} command or @kbd{M-x ispell @key{RET}}), you
-want the spell checking program to skip certain macro arguments and
-environments, most notably the arguments of referencing macros and the
-contents of verbatim environments.  The skipped parts are controlled by
-variable @code{ispell-tex-skip-alists} provided by @file{ispell.el}.
-@AUCTeX{} has a library which can be added to this variable depending on
-the value of @code{TeX-ispell-extend-skip-list} which is set to @code{t}
-by default.
-
-@defopt TeX-ispell-extend-skip-list
-This boolean option controls whether @AUCTeX{} activates its extension
-for skipping certain macro arguments and environments when spell
-checking.
-
-When non-@code{nil}, @AUCTeX{} loads the file @file{tex-ispell.el} and
-adds its content to @code{ispell-tex-skip-alists}.  This library can and
-will never be complete, but the interface can be used to add selected
-and private macro names within your init file or on a file local basis.
-
-@code{ispell-tex-skip-alists} has the following structure:

-  (KEY . REGEXP) - skip to the end of REGEXP.
-                   REGEXP may be string or symbol.
-  (KEY REGEXP) - skip to end of REGEXP.  REGEXP must be a string.
-  (KEY FUNCTION ARGS) - FUNCTION called with ARGS

-@end lisp
-
-Let's go through the first list of @code{ispell-tex-skip-alists} line by
-line:
-@lisp
-("\\\\addcontentsline"         ispell-tex-arg-end 2)
-@end lisp
-@code{KEY} is the string @code{"\\\\addcontentsline"}, @code{FUNCTION}
-is @code{ispell-tex-arg-end} called with @code{ARGS}, here @code{2}.
-@code{ispell-tex-arg-end} is a function provided by @file{ispell.el}
-which skips as many subsequent optional arguments in square brackets as
-it sees and then skips @code{ARGS} number of mandatory arguments in
-braces.  Omitting @code{ARGS} means skip @code{1} mandatory argument.
-In practice, when you have something like this in your document:
-@example
-\addcontentsline@{toc@}@{chapter@}@{Some text@}
-@end example
-The first two arguments are left out and @samp{Some text} will be spell
-checked.  For the next line
-@lisp
-("\\\\\\([aA]lph\\|arabic\\)"  ispell-tex-arg-end)
-@end lisp
-the name of the counter as argument is skipped.  Next line is
-@lisp
-("\\\\makebox"                 ispell-tex-arg-end 0)
-@end lisp
-where only optional arguments are skipped, the first mandatory argument
-is checked, e.g.
-@example
-\makebox[0pt][l]@{Some text@}
-@end example
-Finally, the next line
-@lisp
-("\\\\documentclass" . "\\\\begin@{document@}"))
-@end lisp
-ensures that the entire preamble of a document is discarded.  Second
-list works the same; it is more convenient for environments since
-@code{KEY} is wrapped inside @code{\begin@{@}}.
-
-@findex TeX-ispell-skip-setcar
-@findex TeX-ispell-skip-setcdr
-@AUCTeX{} provides two functions to add items to car and cdr of
-@code{ispell-tex-arg-end}, namely @code{TeX-ispell-skip-setcar} and
-@code{TeX-ispell-skip-setcdr}.  The argument of these functions is
-exactly as in @code{ispell-tex-skip-alists}.  Additions can be done via
-init file, e.g.:
-@lisp
-(eval-after-load "tex-ispell"
-  '(progn
-     (TeX-ispell-skip-setcar
-      '(("\\\\mymacro" ispell-tex-arg-end)))
-     (TeX-ispell-skip-setcdr
-      '(("myverbatim" . "\\\\end@{myverbatim@}")))))
-@end lisp
-
-Another possibility is to use file local additions at the end of your
-@TeX{} file, e.g.:
-@example
-%%% Local Variables:
-%%% mode: latex
-%%% TeX-master: t
-%%% eval: (TeX-ispell-skip-setcar '(("\\\\mymacro" . "@{[-0-9]+@}")))
-%%% End:
-@end example
-
-@findex TeX-ispell-tex-arg-end
-Finally, @AUCTeX{} provides a function called
-@code{TeX-ispell-tex-arg-end} which sees more arguments than
-@code{ispell-tex-arg-end}.  Refer to its doc string for more
-information.
-@end defopt
-
-@AUCTeX{} also provides a facility to skip the argument of in-line
-verbatim macros like @samp{\Verb} from @file{fancyvrb.sty} or
-@samp{\mintinline} from @file{minted.sty}.  Characters delimiting the
-verbatim text are stored in @code{TeX-ispell-verb-delimiters}.
-
-@defopt TeX-ispell-verb-delimiters
-String with delimiters recognized for in-line verbatim macros.  This
-variable is initialized to @samp{!|#~"*/+^-}.  Since this string is
-used to build a character alternative inside a regular expression,
-special characters @samp{^} and @samp{-} should come last.  Other
-characters like opening brace @samp{@{}, asterisk @samp{*} or at sign
-@samp{@@} should be avoided as they are not recognized by
-@file{font-latex.el}.

-
-@node Processor Options
-@subsection Options for @TeX{} Processors
-
-There are some options you can customize affecting which processors are
-invoked or the way this is done and which output they produce as a
-result.  These options control if @acronym{DVI} or @acronym{PDF} output
-should be produced, if @TeX{} should be started in interactive or
-nonstop mode, if source specials or a Sync@TeX{} file should be produced
-for making inverse and forward search possible or which @TeX{} engine
-should be used instead of regular @TeX{}, like PDF@TeX{}, Omega or
-Xe@TeX{}, and the style error messages are printed with.
-
-@deffn Command TeX-PDF-mode
-@kindex C-c C-t C-p
-@vindex TeX-PDF-mode
-@cindex PDF mode
-(@kbd{C-c C-t C-p})
-This command toggles the @acronym{PDF} mode of @AUCTeX{}, a buffer-local
-minor mode which is enabled by default.  You can customize
-@code{TeX-PDF-mode} to give it a different default or set it as a file
-local variable on a per-document basis.  This option usually results in
-calling either PDF@TeX{} or ordinary @TeX{}.
-@end deffn
-
-@defopt TeX-DVI-via-PDFTeX
-If this is set, @acronym{DVI} will also be produced by calling
-PDF@TeX{}, setting @code{\pdfoutput=0}.  This makes it possible to use
-PDF@TeX{} features like character protrusion even when producing
-@acronym{DVI} files.  Contemporary @TeX{} distributions do this anyway,
-so that you need not enable the option within @AUCTeX{}.
-@end defopt
-
-@deffn Command TeX-interactive-mode
-@kindex C-c C-t C-i
-@vindex TeX-interactive-mode
-(@kbd{C-c C-t C-i}) This command toggles the interactive mode of
-@AUCTeX{}, a global minor mode.  You can customize
-@code{TeX-interactive-mode} to give it a different default.  In
-interactive mode, @TeX{} will pause with an error prompt when errors are
-encountered and wait for the user to type something.

-@cindex Source specials
-@cindex PDFSync
-@deffn Command TeX-source-correlate-mode
-@kindex C-c C-t C-s
-@vindex TeX-source-correlate-mode
-(@kbd{C-c C-t C-s}) Toggles support for forward and inverse search.
-Forward search refers to jumping to the place in the previewed document
-corresponding to where point is located in the document source and
-inverse search to the other way round.  @xref{I/O Correlation}.
-
-You can permanently activate @code{TeX-source-correlate-mode} by
-customizing the variable @code{TeX-source-correlate-mode}.  There is a
-bunch of customization options for the mode, use @kbd{M-x
-customize-group @key{RET} TeX-view @key{RET}} to find out more.
-
-@vindex TeX-source-correlate-method
-@AUCTeX{} is aware of three different means to do I/O correlation:
-source specials (only DVI output), the pdfsync @LaTeX{} package (only
-PDF output) and Sync@TeX{}.  The choice between source specials and
-Sync@TeX{} can be controlled with the variable
-@code{TeX-source-correlate-method}.
-
-Should you use source specials it has to be stressed @emph{very}
-strongly however, that source specials can cause differences in page
-breaks and spacing, can seriously interfere with various packages and
-should thus @emph{never} be used for the final version of a document.
-In particular, fine-tuning the page breaks should be done with source
-specials switched off.
-@end deffn
-
-Sometimes you are requested, by journal rules or packages, to compile
-the document into @acronym{DVI} output.  Thus, if you want a
-@acronym{PDF} document in the end you can either use Xe@TeX{} engine,
-see below for information about how to set engines, or compile the
-document with @command{tex} and then convert to @acronym{PDF} with
-@command{dvips}--@command{ps2pdf} before viewing it.  In addition,
-current Japanese @TeX{} engines cannot generate @acronym{PDF} directly
-so they rely on @acronym{DVI}-to-@acronym{PDF} converters.  Usually
-@command{dvipdfmx} command is used for this purpose.  You can use the
-@code{TeX-PDF-from-DVI} variable to let @AUCTeX{} know you want to
-generate the final @acronym{PDF} by converting a @acronym{DVI} file.
-
-@defopt TeX-PDF-from-DVI
-This option controls if and how to produce a @acronym{PDF} file by
-converting a @acronym{DVI} file.
-
-When @code{TeX-PDF-mode} is non-nil, if @code{TeX-PDF-from-DVI} is
-non-nil too the document is compiled to @acronym{DVI} instead of
-@acronym{PDF}.  When the document is ready, @kbd{C-c C-c} will suggest
-to run the converter to @acronym{PDF} or an intermediate format.
-
-If non-nil, @code{TeX-PDF-from-DVI} should be the name of the command in @code{TeX-command-list},
-as a string, used to convert the @acronym{DVI} file to @acronym{PDF} or
-to an intermediate format.  Values currently supported are:
-@itemize
-@item
-@code{"Dvips"}: the @acronym{DVI} file is converted to @acronym{PS} with
-@command{dvips}.  After successfully running it, @command{ps2pdf} will
-be the default command to convert the @acronym{PS} file to
-@acronym{PDF}.
-@item
-@code{"Dvipdfmx"}: the @acronym{DVI} file is converted to @acronym{PDF}
-with @command{dvipdfmx}.
-@end itemize
-(case is significant; note the uppercase @samp{D} in both strings)
-When the @acronym{PDF} file is finally ready, the next suggested command
-will be @samp{View} to open the viewer.
-
-This option can also be set as a file local variable, in order to use
-this conversion on a per-document basis.
-
-Recall the whole sequence of @kbd{C-c C-c} commands can be replaced by
-the single @kbd{C-c C-a}.
-@end defopt
-
-@AUCTeX{} also allows you to easily select different @TeX{} engines for
-processing, either by using the entries in the @samp{TeXing Options}
-submenu below the @samp{Command} menu or by calling the function
-@code{TeX-engine-set}.  These eventually set the variable
-@code{TeX-engine} which you can also modify directly.
-
-@defopt TeX-engine
-This variable allows you to choose which @TeX{} engine should be used
-for typesetting the document, i.e.@: the executables which will be used
-when you invoke the @samp{TeX} or @samp{LaTeX} commands.  The value
-should be one of the symbols defined in @code{TeX-engine-alist-builtin}
-or @code{TeX-engine-alist}.  The symbols @samp{default}, @samp{xetex},
-@samp{luatex} and @samp{omega} are available from the built-in list.
-@end defopt
-
-Note that @code{TeX-engine} is buffer-local, so setting the variable
-directly or via the above mentioned menu or function will not take
-effect in other buffers.  If you want to activate an engine for all
-@AUCTeX{} modes, set @code{TeX-engine} in your init file, e.g.@: by using
-@kbd{M-x customize-option @key{RET}}.  If you want to activate it for a
-certain @AUCTeX{} mode only, set the variable in the respective mode

-@code{TeX-command}, @code{LaTeX-command}, @code{TeX-Omega-command},
-@code{LaTeX-Omega-command}, @code{ConTeXt-engine} and
-@code{ConTeXt-Omega-engine}.  The rest of the executables is defined
-directly in @code{TeX-engine-alist-builtin}.  If you want to override an
-entry from that, add an entry to @code{TeX-engine-alist} that starts
-with the same symbol as that the entry in the built-in list and specify
-the executables you want to use instead.  You can also add entries to
-@code{TeX-engine-alist} in order to add support for engines not covered
-per default.
-
-@defopt TeX-engine-alist
-Alist of @TeX{} engines and associated commands.  Each entry is a list with
-a maximum of five elements.  The first element is a symbol used to
-identify the engine.  The second is a string describing the engine.  The
-third is the command to be used for plain @TeX{}.  The fourth is the
-command to be used for @LaTeX{}.  The fifth is the command to be used for
-the @option{--engine} parameter of @ConTeXt{}'s @samp{texexec} program.  Each
-command can either be a variable or a string.  An empty string or nil
-means there is no command available.
-@end defopt
-
-In some systems, Emacs cannot inherit the @env{PATH} environment variable from
-the shell and thus @AUCTeX{} may not be able to run @TeX{} commands.
-Before running them, @AUCTeX{} checks if it is able to find those commands
-and will warn you in case it fails.  You can skip this test by changing
-the option @code{TeX-check-TeX}.
-
-@defopt TeX-check-TeX
-@vindex TeX-command
-@vindex TeX-check-TeX-command-not-found
-If non-nil, @AUCTeX{} will check if it is able to find a working @TeX{}

-@end defopt
-
-Some @LaTeX{} packages requires the document to be compiled with a
-specific engine.  Notable examples are @samp{fontspec} and @samp{polyglossia}
-packages, which require Lua@TeX{} and Xe@TeX{} engines.  If you try to
-compile a document which loads one of such packages and the set engine
-is not one of those allowed you will be asked to select a different
-engine before running the @LaTeX{} command.  If you do not want to be
-warned by @AUCTeX{} in these cases, customize the option
-@code{TeX-check-engine}.
-
-@defopt TeX-check-engine
-This boolean option controls whether @AUCTeX{} should check the correct
-engine has been set before running @LaTeX{} commands.
-@end defopt
-
-As shown above, @AUCTeX{} handles in a special way most of the main
-options that can be given to the @TeX{} processors.  When you need to
-pass to the @TeX{} processor arbitrary options not handled by @AUCTeX{},
-you can use the file local variable @code{TeX-command-extra-options}.
-@defopt TeX-command-extra-options
-String with the extra options to be given to the TeX processor.  For
-example, if you need to enable the shell escape feature to compile a
-document, add the following line to the list of local variables of the
-source file:
-@example
-%%% TeX-command-extra-options: "-shell-escape"
-@end example
-By default this option is not safe as a file-local variable because a
-specially crafted document compiled with shell escape enabled can be
-used for malicious purposes.
-@end defopt
-
-You can customize @AUCTeX{} to show the processor output as it is
-produced.
-
-@defopt TeX-show-compilation
-If non-nil, the output of @TeX{} compilation is shown in another window.

-
-@ConTeXt{} users can choose between Mark II and Mark IV versions.  This
-is controlled by @code{ConTeXt-Mark-version} option.

-@subsection Starting Viewers
-
-Viewers are normally invoked by pressing @kbd{C-c C-c} once the document
-is formatted, which will propose the @samp{View} command, or by activating the
-respective entry in the Command menu.  Alternatively you can type
-@kbd{C-c C-v} which calls the function @code{TeX-view}.
-
-@deffn Command TeX-view
-@kindex C-c C-v
-(@kbd{C-c C-v}) Start a viewer without confirmation.  The viewer is
-started either on a region or the master file, depending on the last
-command issued.  This is especially useful for jumping to the location
-corresponding to point in the viewer when using
-@code{TeX-source-correlate-mode}.
-@end deffn
-
-@AUCTeX{} will try to guess which type of viewer (@acronym{DVI},
-PostScript or @acronym{PDF}) has to be used and what options are to be
-passed over to it.  This decision is based on the output files present
-in the working directory as well as the class and style options used in
-the document.  For example, if there is a @acronym{DVI} file in your
-working directory, a @acronym{DVI} viewer will be invoked.  In case of a
-@acronym{PDF} file it will be a @acronym{PDF} viewer.  If you specified
-a special paper format like @samp{a5paper} or use the @samp{landscape}
-option, this will be passed to the viewer by the appropriate options.
-Especially some @acronym{DVI} viewers depend on this kind of information
-in order to display your document correctly.  In case you are using
-@samp{pstricks} or @samp{psfrag} in your document, a @acronym{DVI}
-viewer cannot display the contents correctly and a PostScript viewer
-will be invoked instead.
-
-The association between the tests for the conditions mentioned above and
-the viewers is made in the variable @code{TeX-view-program-selection}.
-Therefore this variable is the starting point for customization if you
-want to use other viewers than the ones suggested by default.
-
-@defopt TeX-view-program-selection
-This is a list of predicates and viewers which is evaluated from front
-to back in order to find out which viewer to call under the given
-conditions.  In the first element of each list item you can reference
-one or more predicates defined in @code{TeX-view-predicate-list} or
-@code{TeX-view-predicate-list-builtin}.  In the second element you can
-reference a viewer defined in @code{TeX-view-program-list} or
-@code{TeX-view-program-list-builtin}.  The viewer of the first item with
-a positively evaluated predicate is selected.
-@end defopt
-
-So @code{TeX-view-program-selection} only contains references to the
-actual implementations of predicates and viewer commands respectively
-which can be found elsewhere.  @AUCTeX{} comes with a set of
-preconfigured predicates and viewer commands which are stored in the
-variables @code{TeX-view-predicate-list-builtin} and
-@code{TeX-view-program-list-builtin} respectively.  If you are not
-satisfied with those and want to overwrite one of them or add your own
-definitions, you can do so via the variables
-@code{TeX-view-predicate-list} and @code{TeX-view-program-list}.
-
-@defopt TeX-view-predicate-list
-This is a list of predicates for viewer selection and invocation.  The
-first element of each list item is a symbol and the second element a
-Lisp form to be evaluated.  The form should return nil if the predicate
-is not fulfilled.
-
-A built-in predicate from @code{TeX-view-predicate-list-builtin} can be
-overwritten by defining a new predicate with the same symbol.
-@end defopt
-
-@defopt TeX-view-program-list
-This is a list of viewer specifications each consisting of a symbolic
-name and either a command line or a function to be invoked when the
-viewer is called.  If a command line is used, parts of it can be
-conditionalized by prefixing them with predicates from
-@code{TeX-view-predicate-list} or
-@code{TeX-view-predicate-list-builtin}.  (See the doc string for the
-exact format to use.)  The command line can also contain placeholders as
-defined in @code{TeX-expand-list} and @code{TeX-expand-list-builtin}
-which are expanded before the viewer is called.
-
-The third element of each item is a string, or a list of strings, with
-the name of the executable, or executables, needed to open the output
-file in the viewer.  Placeholders defined in @code{TeX-expand-list} and
-@code{TeX-expand-list-builtin} can be used here.  This element is
-optional and is used to check whether the viewer is actually available
-on the system.
-
-A built-in viewer spec from @code{TeX-view-program-list-builtin} can be
-overwritten by defining a new viewer spec with the same name.
-@end defopt
-
-After the viewer is called via either the @samp{View} command or the key stroke
-@kbd{C-c C-v}, the window system focus goes and stays on the viewer.  If
-you prefer that the focus is pulled back to Emacs immediately after that
-and you are using evince-compatible viewer, customize the option
-@code{TeX-view-enince-keep-focus}.
-
-@defopt TeX-view-evince-keep-focus
-When this option is non-nil and the viewer is compatible with evince,
-the focus is pulled back to Emacs immediately after the viewer is
-invoked or refreshed from within @AUCTeX{}.
-@end defopt
-
-Note that the viewer selection and invocation as described above will
-only work if certain default settings in @AUCTeX{} are intact.  For one,
-the whole viewer selection machinery will only be triggered if there is
-no @samp{%V} expander in @code{TeX-expand-list}.  So if you have trouble
-with the viewer invocation you might check if there is an older
-customization of the variable in place.  In addition, the use of a
-function in @code{TeX-view-program-list} only works if the @samp{View} command
-in @code{TeX-command-list} makes use of the hook
-@code{TeX-run-discard-or-function}.

-Method to use for enabling forward and inverse search.  This can be
-@samp{source-specials} if source specials should be used, @samp{synctex}
-if Sync@TeX{} should be used, or @samp{auto} if @AUCTeX{} should decide.
-
-When the variable is set to @samp{auto}, @AUCTeX{} will always use
-Sync@TeX{} if your @command{latex} processor supports it, source specials
-otherwise.  You must make sure your viewer supports the same method.
-
-It is also possible to specify a different method depending on the
-output, either @acronym{DVI} or @acronym{PDF}, by setting the variable to an alist of the
-kind
-@lisp
-((dvi . @samp{<source-specials or synctex>})
- (pdf . @samp{<source-specials or synctex>}))
-@end lisp
-in which the CDR of each entry is a symbol specifying the method to be
-used in the corresponding mode.  The default value of the variable is
-@lisp
-((dvi . source-specials)
- (pdf . synctex))
-@end lisp
-which is compatible with the majority of viewers.
-@end defopt
-
-@findex TeX-view
-Forward search happens automatically upon calling the viewer, e.g.@: by
-typing @kbd{C-c C-v} (@code{TeX-view}).  This will open the viewer or
-bring it to front and display the output page corresponding to the
-position of point in the source file.  @AUCTeX{} will automatically pass
-the necessary command line options to the viewer for this to happen.
-
-@vindex TeX-source-correlate-map
-@findex TeX-view-mouse
-You can also make special mouse event do forward search at the clicked
-position.  Use @code{TeX-source-correlate-map}@footnote{The keymap name is
-@code{TeX-source-correlate-map}, not @code{TeX-source-correlate-mode-map}.
-Actually, this keymap isn't implemented as minor mode map of
-@code{TeX-source-correlate-mode}, in order that its bindings don't affect
-buffers outside of @AUCTeX{}.} and @code{TeX-view-mouse} like this:
-@lisp
-(eval-after-load "tex"
-  '(define-key TeX-source-correlate-map [C-down-mouse-1]
-               #'TeX-view-mouse))
-@end lisp
-This example binds @kbd{C-down-mouse-1}, which usually opens a concise
-menu to select buffer, to the command to do forward search.
-
-@vindex TeX-source-correlate-start-server
-Upon opening the viewer you will be asked if you want to start a server
-process (Gnuserv or Emacs server) which is necessary for inverse search.
-This happens only if there is no server running already.  You can
-customize the variable @code{TeX-source-correlate-start-server} to
-inhibit the question and always or never start the server respectively.
-
-@defopt TeX-source-correlate-start-server
-If @code{TeX-source-correlate-mode} is active and a viewer is invoked,
-the default behavior is to ask if a server process should be started.
-Set this variable to @code{t} if the question should be inhibited and
-the server should always be started.  Set it to @code{nil} if the server
-should never be started.  Inverse search will not be available in the
-latter case.
-@end defopt
-
-Inverse search, i.e.@: jumping to the part of your document source in
-Emacs corresponding to a certain position in the viewer, is triggered
-from the viewer, typically by a mouse click.  Refer to the documentation
-of your viewer to find out how it has to be configured and what you have
-to do exactly.  In xdvi you normally have to use @kbd{C-down-mouse-1}.
-
-@vindex TeX-source-correlate-start-server
-Note that inverse search with the Evince @acronym{PDF} viewer or its MATE fork
-Atril might fail in raising the Emacs frame after updating point in your
-document's buffer.  There is simply no way to raise the Emacs frame
-reliably accross different operating systems and different window
-managers with their different focus stealing policies.  If the Emacs
-frame is not raised after performing an inverse search from Evince or
-Atril, you can customize the following option.
-
-@defopt TeX-raise-frame-function
-A function that will be called after performing an inverse search from
-Evince or Atril in order to raise the current Emacs frame.
-
-If your Emacs frame is already raised in that situation, just
-leave this variable set to its default value
-@code{raise-frame}.  Otherwise, here are some alternative
-settings that work for some users.
-
-@lisp
-;; @r{Alternative 1: For some users, @t{`x-focus-frame'} works.}
-(setq TeX-raise-frame-function #'x-focus-frame)
-
-;; @r{Alternative 2: Under GNOME 3.20 (and probably others), it}
-;; @r{seems some focus stealing prevention policy prohibits that}
-;; @r{some window gets the focus immediately after the user has}
-;; @r{clicked in some other window.  Here waiting a bit before}

-Running @TeX{} or @LaTeX{} will only find regular errors in the
-document, not examples of bad style.  Furthermore, description of the
-errors may often be confusing.  The utilities @code{lacheck} and
-@code{chktex} can be used to find style errors, such as forgetting to
-escape the space after an abbreviation or using @samp{...} instead of
-@samp{\ldots} and other similar problems.  You start @code{lacheck} with
-@kbd{C-c C-c Check @key{RET}} and @code{chktex} with @kbd{C-c C-c ChkTeX
-@key{RET}}.  The result will be a list of errors in the
-@samp{*compilation*} buffer.  You can go through the errors with
-@kbd{C-x `} (@code{next-error}, @pxref{Compilation,,,emacs,The Emacs
-Editor}), which will move point to the location of the next error.
-
-Alternatively, you may want in-buffer notation.  @AUCTeX{} provides
-support for this using the Flymake package in Emacs 26 or newer
-(@pxref{Using Flymake,,,Flymake,GNU Flymake} for details).  To enable,
-call @kbd{M-x flymake-mode @key{RET}} in the buffer or enable it in all
-buffers by adding this to your init file:
-@lisp
-(add-hook 'LaTeX-mode-hook #'flymake-mode)
-@end lisp
-Note that @AUCTeX{} currently only provides support for using
-@code{chktex} as the flymake backend.
-
-Each of the two utilities @code{lacheck} and @code{chktex} will find
-some errors the other doesn't, but @code{chktex} is more configurable,
-allowing you to create your own errors.  You may need to install the
-programs before using them.  You can get @code{lacheck} from
-URL:@url{https://www.ctan.org/pkg/lacheck} and

-
-You may wish to spread a document over many files (as you are likely to do if
-there are multiple authors, or if you have not yet discovered the power
-of the outline commands (@pxref{Outline})).  This can be done by having a
-``master'' file in which you include the various files with the @TeX{}
-macro @samp{\input} or the @LaTeX{} macro @samp{\include}.  These
-files may also include other files themselves.  However, to format the
-document you must run the commands on the top level master file.
-
-When you, for example, ask @AUCTeX{} to run a command on the master file,
-it has no way of knowing the name of the master file.  By default,
-it will assume that the current file is the master file.  If you insert
-the following in your init file (@file{init.el} or @file{.emacs}), @AUCTeX{} will use a more
-advanced algorithm.
-
-@lisp
-(setq-default TeX-master nil) ; @r{Query for master file.}
-@end lisp
-
-In this case, @AUCTeX{} will ask for the name of the master file
-associated with the buffer.  To avoid asking you again, @AUCTeX{} will
-automatically insert the name of the master file as a file variable
-(@pxref{File Variables,,,emacs,The Emacs Editor}).  You can also insert
-the file variable yourself, by putting the following text at the end of
-your files.
-
-@example
-%%% Local Variables:
-%%% TeX-master: "master"
-%%% End:
-@end example
-
-You should always set this variable to the name of the top level document.  If
-you always use the same name for your top level documents, you can set
-@code{TeX-master} in your init file such as @file{init.el} or @file{.emacs}.
-
-@lisp
-(setq-default TeX-master "master") ; @r{All master files called @t{"master"}.}
-@end lisp
-
-@defopt TeX-master
-The master file associated with the current buffer.  If the file being
-edited is actually included from another file, then you can tell @AUCTeX{}
-the name of the master file by setting this variable.  If there are
-multiple levels of nesting, specify the top level file.
-
-If this variable is @code{nil}, @AUCTeX{} will query you for the
-name.
-
-If the variable is @code{t}, then @AUCTeX{} will assume the file is a master
-file itself.
-
-If the variable is @code{shared}, then @AUCTeX{} will query for the name,
-but will not change the file.

-
-If you dislike @AUCTeX{} automatically modifying your files, you can

-@end deffn
-
-@AUCTeX{} keeps track of macros, environments, labels, and style
-files that are used in a given document.  For this to work with

-information about the files in the document.  This is done by having an
-@file{auto} subdirectory placed in the directory where your document is
-located.  Each time you save a file, @AUCTeX{} will write information
-about the file into the @file{auto} directory.  When you load a file,
-@AUCTeX{} will read the information in the @file{auto} directory
-about the file you loaded @emph{and the master file specified by
-@code{TeX-master}}.  Since the master file (perhaps indirectly) includes
-all other files in the document, @AUCTeX{} will get information from
-all files in the document.  This means that you will get from each file,
-for example, completion for all labels defined anywhere in the document.
-

-@section Automatic Parsing of @TeX{} Files
-@cindex Parsing @TeX{}
-@cindex Automatic Parsing
-@cindex Tabs
-@cindex Tabify
-@cindex Untabify
-
-@AUCTeX{} depends heavily on being able to extract information from the
-buffers by parsing them.  Since parsing the buffer can be somewhat slow,
-the parsing is initially disabled.  You are encouraged to enable them by
-adding the following lines to your init file such as @file{init.el} or @file{.emacs}.
-
-@lisp
-(setq TeX-parse-self t) ; @r{Enable parse on load.}
-(setq TeX-auto-save t) ; @r{Enable parse on save.}
-@end lisp
-
-The latter command will make @AUCTeX{} store the parsed information in
-an @file{auto} subdirectory in the directory each time the @TeX{} files
-are stored, @pxref{Automatic Local}.  If @AUCTeX{} finds the pre-parsed
-information when loading a file, it will not need to reparse the buffer.
-The information in the @file{auto} directory is also useful for
-multifile documents, @pxref{Multifile}, since it allows each file to
-access the parsed information from all the other files in the document.
-This is done by first reading the information from the master file, and
-then recursively the information from each file stored in the master
-file.
-
-The variables can also be set on a per file basis, by changing the file
-local variables.
-
-@example
-%%% Local Variables:
-%%% TeX-parse-self: t
-%%% TeX-auto-save: t
-%%% End:
-@end example
-
-Even when you have disabled the automatic parsing, you can force the
-generation of style information by pressing @kbd{C-c C-n}.  This is
-often the best choice, as you will be able to decide when it is
-necessary to reparse the file.
-
-@defopt TeX-parse-self
-Parse file after loading it if no style hook is found for it.
-@end defopt
-
-@defopt TeX-auto-save
-Automatically save style information when saving the buffer.
-@end defopt
-
-@deffn Command TeX-normal-mode @var{arg}
-@kindex C-c C-n
-(@kbd{C-c C-n}) Remove all information about this buffer, and apply the
-style hooks again.  Save buffer first including style information.  With
-optional argument, also reload the style hooks.
-@end deffn
-
-When @AUCTeX{} saves your buffer, it can optionally convert all tabs in
-your buffer into spaces.
-Tabs confuse @AUCTeX{}'s error message parsing and so should generally be
-avoided.  However, tabs are significant in some environments, and so by
-default @AUCTeX{} does not remove them.
-To convert tabs to spaces when saving a buffer, insert the
-following in your init file such as @file{init.el} or @file{.emacs}:
-
-@lisp
-(setq TeX-auto-untabify t)
-@end lisp
-
-@defopt TeX-auto-untabify
-Automatically remove all tabs from a file before saving it.
-@end defopt
-
-Instead of disabling the parsing entirely, you can also speed it
-significantly up by limiting the information it will search for (and
-store) when parsing the buffer.  You can do this by setting the default
-values for the buffer local variables @code{TeX-auto-regexp-list} and
-@code{TeX-auto-parse-length} in your init file such as @file{init.el} or @file{.emacs}.
-
-@lisp
-;; @r{Only parse LaTeX class and package information.}
-(setq-default TeX-auto-regexp-list 'LaTeX-auto-minimal-regexp-list)
-;; @r{The class and package information is usually near the beginning.}
-(setq-default TeX-auto-parse-length 2000)
-@end lisp
-
-This example will speed the parsing up significantly, but @AUCTeX{}
-will no longer be able to provide completion for labels, macros,
-environments, or bibitems specified in the document, nor will it know
-what files belong to the document.
-
-These variables can also be specified on a per file basis, by changing
-the file local variables.
-
-@example
-%%% Local Variables:
-%%% TeX-auto-regexp-list: TeX-auto-full-regexp-list

-@subsubsection Typing and Displaying Non-ASCII Characters
-
-First you will need a way to write non-ASCII characters.  You can either
-use macros, or teach @TeX{} about the @acronym{ISO} character sets.  I prefer the
-latter, it has the advantage that the usual standard emacs word
-movement and case change commands will work.
-
-Recommended encoding for @LaTeX{} document is @acronym{UTF}-8.  Recent
-@LaTeX{}2e has native support for @acronym{UTF}-8.  If your @LaTeX{}2e is
-not recent enough, just add @samp{\usepackage[utf8]@{inputenc@}}.
-
-You can still use @acronym{ISO} 8859 Latin 1 encoding with
-@samp{\usepackage[latin1]@{inputenc@}}.
-
-To be able to display non-ASCII characters you will need an appropriate
-font.  All Emacs versions supported by current @AUCTeX{} can display 8-bit
-characters, provided that suitable fonts are installed.
-
-@c FIXME: These are considered as kind of obsolete, aren't they?
-A compromise is to use an European character set when editing the file,
-and convert to @TeX{} macros when reading and writing the files.

-
-To write Japanese text with @AUCTeX{}, you need the versions of
-@TeX{} and Emacs that support Japanese.  @AUCTeX{} supports three
-Japanese @TeX{} engines by default: NTT j@TeX{}, ASCII p@TeX{} and
-up@TeX{}.
-
-Activate @code{japanese-plain-tex-mode} or @code{japanese-latex-mode} to
-use the Japanese @TeX{} engines.  If it doesn't work, send mail to
-Masayuki Ataka @email{masayuki.ataka@@gmail.com} or Ikumi Keita
-@email{ikumikeita@@jcom.home.ne.jp}, who currently concern with stuff
-related to Japanese in @AUCTeX{}.  None of the primary @AUCTeX{}
-maintainers understand Japanese, so they cannot help you.
-
-It is recommended to enable @code{TeX-parse-self} for typical Japanese
-@LaTeX{} users.  When enabled, @code{japanese-latex-mode} selects the
-suitable Japanese @TeX{} engine automatically based on the class file
-name (such as @code{jbook}, @code{jsarticle} and @code{tjreport}) and
-its option.  @xref{Parsing Files}.
-
-It is important to select the suitable Japanese @TeX{} engine because
-the selected engine determines the command name such as @command{platex}
-and @command{uptex} to typeset the document.  If you find that wrong
-command is used, check the value of @code{TeX-engine} on that buffer.
-If the value does not suit the current document, change the value by the
-@samp{TeXing Options} submenu below the @samp{Command} menu.
-@xref{Processor Options}.
-
-To make the selected engine to persist across Emacs sessions, there are
-two ways from which you can choose one according to your needs:
-
-@enumerate
-@item
-If you use a specific engine (almost) exclusively, customize the option
-@code{japanese-TeX-engine-default}.
-
-@defopt japanese-TeX-engine-default
-The default @code{TeX-engine} in Japanese @TeX{} mode.
-
-The default value is @samp{ptex}.
-@end defopt
-@item
-If you want to set the engine on a per file basis, use the file local
-variables to set @code{TeX-engine}.
-
-Here is a sample code to set @code{TeX-engine} to @samp{uptex}:
-
-@example
-%%% Local Variables:
-%%% mode: japanese-latex
-%%% TeX-engine: uptex
-%%% End:
-@end example
-@end enumerate
-
-In the both cases above, the valid value is one of @samp{ptex},
-@samp{jtex} and @samp{uptex}.
-
-You can override the command names associated with the above three
-engines or define your own engine by customizing
-@code{TeX-engine-alist}.  @xref{Processor Options}.
-
-It is sometimes necessary to use an engine which differs from the one
-@AUCTeX{} selects automatically.  For example, even when you want to use
-@code{j-article} document class deliberately with ASCII p@LaTeX{},
-@AUCTeX{} selects NTT j@LaTeX{} command if @code{TeX-parse-self} is
-enabled, because @code{j-article} originally belongs to NTT j@LaTeX{}.
-In such cases, use the file local variable method above to select the
-engine you intend to use.
-
-If you usually use @AUCTeX{} in Japanese, setting the following
-variables is useful.
-
-@defopt TeX-default-mode
-Mode to enter for a new file when it cannot be determined whether the
-file is plain @TeX{} or @LaTeX{} or what.
-
-If you want to enter Japanese @LaTeX{} mode whenever this may happen,
-set the variable like this:
-@lisp
-(setq TeX-default-mode 'japanese-latex-mode)
-@end lisp
-@end defopt
-
-@defopt japanese-LaTeX-default-style
-The default style/class when creating a new Japanese @LaTeX{} document.
-
-The default value is @samp{"jarticle"}.
-@end defopt
-
-It is recommended also for Japanese users to customize the option
-@code{TeX-PDF-from-DVI} to @samp{"Dvipdfmx"}.  @xref{Processor Options}.
-
-There are three customize options with regard to the encoding of
-Japanese text.
-
-@defopt japanese-TeX-use-kanji-opt-flag
-If non-nil, @AUCTeX{} adds @option{-kanji} option to the typesetting
-command when @code{TeX-engine} is @samp{ptex}.
-@end defopt
-
-Usually @AUCTeX{} guesses the right coding systems for input to and
-output from the Japanese @TeX{} process, but you can override them by
-the following two customize options.
-
-@defopt TeX-japanese-process-input-coding-system
-If non-nil, used for encoding input to Japanese @TeX{} process.
-When @code{nil}, @AUCTeX{} tries to choose suitable coding system.
-@end defopt
-
-@defopt TeX-japanese-process-output-coding-system
-If non-nil, used for decoding output from Japanese @TeX{} process.
-When @code{nil}, @AUCTeX{} tries to choose suitable coding system.
-@end defopt
-
-The former customize options @code{japanese-TeX-command-default},

-Since @AUCTeX{} is so highly customizable, it makes sense that it is able
-to customize itself.  The automatic customization consists of scanning
-@TeX{} files and extracting symbols, environments, and things like that.
-
-The automatic customization is done on three different levels.  The
-global level is the level shared by all users at your site, and consists
-of scanning the standard @TeX{} style files, and any extra styles added
-locally for all users on the site.  The private level deals with those
-style files you have written for your own use, and use in different
-documents.  You may have a @file{~/lib/TeX/} directory where you store
-useful style files for your own use.  The local level is for a specific
-directory, and deals with writing customization for the files for your
-normal @TeX{} documents.
-
-If compared with the environment variable @env{TEXINPUTS}, the
-global level corresponds to the directories built into @TeX{}.  The
-private level corresponds to the directories you add yourself, except for
-@file{.}, which is the local level.

-;;; book.el - Special code for book style.
-
-(TeX-add-style-hook
- "book"
- (lambda () 
-   (LaTeX-largest-level-set "part"))
- TeX-dialect)
-@end lisp
-
-The example is from the @AUCTeX{} sources and is loaded for any @LaTeX{}
-document using the book document class (or style before @LaTeX{}2e).
-(Note that the above code is much simplified for explanatory purpose.)
-The file specifies that the largest kind of section in such a document
-is @samp{part}.  The interesting thing to notice is that the style file
-defines an (anonymous) function, and adds it to the list of loaded style
-hooks by calling @code{TeX-add-style-hook}.
-
-The first time the user indirectly tries to access some style-specific
-information, such as the largest sectioning command available, the style
-hooks for all files directly or indirectly read by the current document
-are executed.  The actual files will only be evaluated once, but the
-hooks will be called for each buffer using the style file.
-
-Note that the basename of the style file and the name of the style hook
-should usually be identical.
-
-@defun TeX-add-style-hook @var{style} @var{hook} &optional @var{dialect-expr}
-Add @var{hook} to the list of functions to run when we use the @TeX{}
-file @var{style} and the current dialect is one in the set derived from
-@var{dialect-expr}.  When @var{dialect-expr} is omitted, then @var{hook}
-is allowed to be run whatever the current dialect is.
-
-@var{dialect-expr} may be one of:
-
-@itemize
-@item
-A symbol indicating a singleton containing one basic @TeX{} dialect,
-this symbol shall be selected among:
-@table @code
-@item :latex

-@item :bibtex
-For all files in Bib@TeX{} mode, or any mode derived thereof.
-@item :texinfo
-For all files in Texinfo mode.
-@item :plain-tex
-For all files in plain-@TeX{} mode, or any mode derived thereof.
-@item :context
-For all files in @ConTeXt{} mode.
-@item :classopt
-For class options of @LaTeX{} document.  This is provided as
-pseudo-dialect for style hooks associated with class options.
-@end table

-@cindex Adding macros
-@cindex Macros, adding
-@cindex Defining macros in style hooks
-
-The most common thing to define in a style hook is new symbols (@TeX{}
-macros).  Most likely along with a description of the arguments to the
-function, since the symbol itself can be defined automatically.
-
-Here are a few examples from @file{latex.el}.
-
-@lisp
-(TeX-add-style-hook
- "latex"
- (lambda ()
-   (TeX-add-symbols
-    '("arabic" TeX-arg-counter)
-    '("label" TeX-arg-define-label)
-    '("ref" TeX-arg-ref)
-    '("newcommand" TeX-arg-define-macro [ "Number of arguments" ] t)
-    '("newtheorem" TeX-arg-define-environment
-      [ TeX-arg-environment "Numbered like" ]
-      t [ TeX-arg-counter "Within counter" ]))))
-@end lisp
-
-@defun TeX-add-symbols @var{symbol} @dots{}
-Add each @var{symbol} to the list of known symbols.
-@end defun
-
-Each argument to @code{TeX-add-symbols} is a list describing one symbol.
-The head of the list is the name of the symbol, the remaining elements
-describe each argument.
-
-If there are no additional elements, the symbol will be inserted with
-point inside braces.  Otherwise, each argument of this function should
-match an argument of the @TeX{} macro.  What is done depends on the argument
-type.
-
-If a macro is defined multiple times, @AUCTeX{} will choose the one with
-the longest definition (i.e.@: the one with the most arguments).
-
-Thus, to overwrite
-@example
-        '("tref" 1) ; @r{one argument}
-@end example
-you can specify
-@example
-        '("tref" TeX-arg-ref ignore) ; @r{two arguments}
-@end example
-
-@code{ignore} is a function that does not do anything, so when you
-insert a @samp{tref} you will be prompted for a label and no more.
-
-You can use the following types of specifiers for arguments:
-
-@table @code
-@item string
-Use the string as a prompt to prompt for the argument.
-
-@item number
-Insert that many braces, leave point inside the first.  0 and -1 are
-special.  0 means that no braces are inserted.  -1 means that braces are
-inserted around the macro and an active region (e.g.@: @samp{@{\tiny
-foo@}}).  If there is no active region, no braces are inserted.
-
-@item nil
-Insert empty braces.
-
-@item t
-Insert empty braces, leave point between the braces.
-
-@item other symbols
-Call the symbol as a function.  You can define your
-own hook, or use one of the predefined argument hooks.
-
-@item list
-If the car is a string, insert it as a prompt and the next
-element as initial input.  Otherwise, call the car of the list with
-the remaining elements as arguments.
-
-@item vector
-Optional argument.  If it has more than one element, parse it
-as a list, otherwise parse the only element as above.  Use square
-brackets instead of curly braces, and is not inserted on empty user
-input.
-@end table
-
-A lot of argument hooks have already been defined.  The first argument to
-all hooks is a flag indicating if it is an optional argument.  It is up
-to the hook to determine what to do with the remaining arguments, if
-any.  Typically the next argument is used to overwrite the default
-prompt.
-
-@ftable @code
-@item TeX-arg-conditional
-Implements if @var{expr} @var{then} @var{else}.  If @var{expr} evaluates
-to true, parse @var{then} as an argument list, else parse @var{else} as an
-argument list.
-
-@item TeX-arg-literal
-Insert its arguments into the buffer.  Used for specifying extra syntax
-for a macro.
-
-@item TeX-arg-free
-Parse its arguments but use no braces when they are inserted.
-
-@item TeX-arg-eval
-Evaluate arguments and insert the result in the buffer.
-
-@item TeX-arg-label
-Prompt for a label completing with known labels.  If Ref@TeX{} is
-active, prompt for the reference format.
-
-@item TeX-arg-ref
-Prompt for a label completing with known labels.  If Ref@TeX{} is
-active, do not prompt for the reference format.  Usually, reference
-macros should use this function instead of @code{TeX-arg-label}.
-
-@item TeX-arg-index-tag
-Prompt for an index tag.  This is the name of an index, not the entry.
-
-@item TeX-arg-index
-Prompt for an index entry completing with known entries.

-
-@item TeX-arg-date
-@vindex TeX-date-format
-Prompt for a date, defaulting to the current date.  The format of the

-change the format when the @samp{babel} package is loaded with a
-specific language, set @code{TeX-date-format} inside the appropriate
-language hook (for details @pxref{European}).
-
-@item TeX-arg-version

-@cindex Adding environments
-@cindex Environments, adding
-@cindex Defining environments in style hooks
-
-Adding support for environments is very much like adding support for
-@TeX{} macros, except that each environment normally only takes one
-argument, an environment hook.  The example is again a short version of
-@file{latex.el}.
-
-@lisp
-(TeX-add-style-hook
- "latex"
- (lambda ()
-   (LaTeX-add-environments
-    '("document" LaTeX-env-document)
-    '("enumerate" LaTeX-env-item)
-    '("itemize" LaTeX-env-item)
-    '("list" LaTeX-env-list))))
-@end lisp
-
-It is completely up to the environment hook to insert the environment,
-but the function @code{LaTeX-insert-environment} may be of some help.
-The hook will be called with the name of the environment as its first
-argument, and extra arguments can be provided by adding them to a list
-after the hook.
-
-For simple environments with arguments, for example defined with
-@samp{\newenvironment}, you can make @AUCTeX{} prompt for the arguments
-by giving the prompt strings in the call to
-@code{LaTeX-add-environments}.  The fact that an argument is optional
-can be indicated by wrapping the prompt string in a vector.
-
-For example, if you have defined a @code{loop} environment with the
-three arguments @var{from}, @var{to}, and @var{step}, you can add
-support for them in a style file.
-
-@example
-%% loop.sty
-
-\newenvironment@{loop@}[3]@{...@}@{...@}
-@end example
-
-@lisp
-;; loop.el
-
-(TeX-add-style-hook
- "loop"
- (lambda ()
-   (LaTeX-add-environments
-    '("loop" "From" "To" "Step"))))
-@end lisp
-
-If an environment is defined multiple times, @AUCTeX{} will choose the
-one with the longest definition.  Thus, if you have an enumerate style
-file, and want it to replace the standard @LaTeX{} enumerate hook above,
-you could define an @file{enumerate.el} file as follows, and place it in
-the appropriate style directory.
-
-@lisp
-(TeX-add-style-hook
- "latex"
- (lambda ()
-   (LaTeX-add-environments
-    '("enumerate" LaTeX-env-enumerate foo))))
-
-(defun LaTeX-env-enumerate (environment &optional _ignore) ...)
-@end lisp
-
-The symbol @code{foo} will be passed to @code{LaTeX-env-enumerate} as
-the second argument, but since we only added it to overwrite the
-definition in @file{latex.el} it is just ignored.
-
-@defun LaTeX-add-environments @var{env} @dots{}
-Add each @var{env} to list of loaded environments.
-@end defun
-
-@defun LaTeX-insert-environment @var{env} [ @var{extra} ]
-Insert environment of type @var{env}, with optional argument @var{extra}.
-@end defun
-
-Following is a list of available hooks for
-@code{LaTeX-add-environments}:
-
-@ftable @code
-@item LaTeX-env-item
-Insert the given environment and the first item.
-
-@item LaTeX-env-figure
-Insert the given figure-like environment with a caption and a label.
-
-@item LaTeX-env-array
-Insert the given array-like environment with position and column
-specifications.
-
-@item LaTeX-env-label
-Insert the given environment with a label.
-
-@item LaTeX-env-list
-Insert the given list-like environment, a specifier for the label and
-the first item.
-
-@item LaTeX-env-minipage
-Insert the given minipage-like environment with position and width
-specifications.
-
-@item LaTeX-env-tabular*
-Insert the given tabular*-like environment with width, position and
-column specifications.
-
-@item LaTeX-env-picture
-Insert the given environment with width and height specifications.
-
-@item LaTeX-env-bib
-Insert the given environment with a label for a bibitem.
-
-@item LaTeX-env-contents
-Insert the given environment with a filename as its argument.
-
-@item LaTeX-env-args
-Insert the given environment with arguments.  You can use this as a hook
-in case you want to specify multiple complex arguments just like in
-elements of @code{TeX-add-symbols}.  This is most useful if the
-specification of arguments to be prompted for with strings and strings
-wrapped in a vector as described above is too limited.
-
-Here is an example from @file{listings.el} which calls a function with
-one argument in order to prompt for a @samp{key=value} list to be inserted as
-an optional argument of the @samp{lstlisting} environment:
-
-@lisp
-(LaTeX-add-environments
- '("lstlisting" LaTeX-env-args
-   [TeX-arg-key-val LaTeX-listings-key-val-options]))
-@end lisp
-@end ftable
-
-Some packages provide environments that are rarely useful to non-expert
-users.  Those should be marked as expert environments using
-@code{LaTeX-declare-expert-environments}.
-
-@defun LaTeX-declare-expert-environments @var{style} @var{environments}...
-Declare @var{environments} as expert environments of @var{style}.
-
-Expert environments are completed depending on @code{TeX-complete-expert-commands}.

-You can also specify bibliographical databases and labels in the style

-usually be automatically generated from the @TeX{} file anyway.
-
-@defun LaTeX-add-bibliographies @var{bibliography} @dots{}
-Add each @var{bibliography} to list of loaded bibliographies.

-@subsubsection Examining Package/Class Options
-
-In @LaTeX{} documents, style hooks can find the package names and those
-options given as optional argument(s) of @samp{\usepackage} in
-@code{LaTeX-provided-package-options}.
-
-@defvar LaTeX-provided-package-options
-Buffer local variable holding alist of options provided to @LaTeX{}
-packages.  Each element is a cons cell @code{(@var{package}
-. @var{option-list})}.  For example, its value will be
-@lisp
-  (("babel" . ("german"))
-   ("geometry" . ("a4paper" "top=2cm" "left=2.5cm" "right=2.5cm"))
-   ...)
-@end lisp
-@end defvar
-
-You can examine whether there is a specific package-option pair by
-@code{LaTeX-provided-package-options-member}.
-
-@defun LaTeX-provided-package-options-member @var{package} @var{option}
-Return non-@code{nil} if @var{option} has been given to @var{package}.
-The value is actually the tail of the list of options given to
-@var{package}.
-@end defun
-
-There are similar facilities for class names and those options given in
-@code{\documentclass} declaration.
-
-@defvar LaTeX-provided-class-options
-Buffer local variable holding alist of options provided to @LaTeX{}
-classes.  Each element is a cons cell @code{(@var{class}
-. @var{option-list})}.  For example, its value will be
-@lisp
-  (("book" . ("a4paper" "11pt" "openany" "fleqn"))
-   ...)
-@end lisp
-@end defvar
-
-@defun LaTeX-provided-class-options-member @var{class} @var{option}
-Return non-@code{nil} if @var{option} has been given to @var{class}.  The
-value is actually the tail of the list of options given to @var{class}.
-@end defun
-
-@defun LaTeX-match-class-option @var{regexp}
-Check if a documentclass option matching @var{regexp} is active.  Return
-first found class option matching @var{regexp}, or nil if not found.
-@end defun
-
-These functions are also useful to implement customized predicate(s) in
-@code{TeX-view-predicate-list}.  @xref{Starting Viewers}.
-
-@subsubsection Adding Support for Option Completion
-When the user inserts @samp{\usepackage} by @kbd{C-c C-m}, @AUCTeX{} asks
-for the optional arguments after the package name is given.  The style
-file of that package can provide completion support for the optional
-arguments.
-
-@defvar LaTeX-@var{packagename}-package-options
-List of optional arguments available for the package.
-@end defvar
-
-Here is an excerption from @samp{acronym.el}:
-@lisp
-(defvar LaTeX-acronym-package-options
-  '("footnote" "nohyperlinks" "printonlyused" "withpage"
-    "smaller" "dua" "nolist")
-  "Package options for the acronym package.")
-@end lisp
-
-When the package accepts key-value style optional arguments, more
-sophisticated completion support is needed.  The package style file can
-provide dynamic completion support by custom elisp function.
-
-@defun LaTeX-@var{packagename}-package-options
-This function should ask the user for optional arguments and return them
-as a string, instead of built-in option query facility.  When this function
-is defined, @AUCTeX{} calls it with no argument.
-@end defun
-
-Here is an excerption from @samp{acro.el}:
-@lisp
-(defun LaTeX-acro-package-options ()
-  "Prompt for package options for the acro package."
-  (TeX-read-key-val t LaTeX-acro-package-options-list))
-@end lisp
-
-As you can see in the above example, a utility function
-@code{TeX-read-key-val} is available to read key-value pair(s) from users.
-
-Note that @code{defvar} or @code{defun} of
-@code{LaTeX-@var{packagename}-package-options} should be at the top level
-of the style file and not inside the style hook, because the style hook is
-not yet called when the user inputs the optional arguments in response to
-@kbd{C-c C-m}.
-
-There are similar facilities for class options.  When the user inserts
-@samp{\documentclass} by @kbd{C-c C-e}, the respective class style file
-can provide completion support for the optional arguments.
-
-@defvar LaTeX-@var{classname}-class-options
-List of optional arguments available for the class.
-@end defvar
-
-@defun LaTeX-@var{classname}-class-options
-Which see.

-@node Hacking the Parser
-@subsection Automatic Extraction of New Things
-@cindex Parsing new macros
-@cindex @file{macro.tex}
-@cindex @file{macro.el}
-@cindex Changing the parser
-
-The automatic @TeX{} information extractor works by searching for
-regular expressions in the @TeX{} files, and storing the matched
-information.  You can add support for new constructs to the parser,
-something that is needed when you add new commands to define symbols.
-
-For example, in the file @file{macro.tex} I define the following macro.
-
-@example
-\newcommand@{\newmacro@}[5]@{%
-\def#1@{#3\index@{#4@@#5~cite@{#4@}@}\nocite@{#4@}@}%
-\def#2@{#5\index@{#4@@#5~cite@{#4@}@}\nocite@{#4@}@}%
-@}
-@end example
-
-@AUCTeX{} will automatically figure out that @samp{newmacro} is a macro
-that takes five arguments.  However, it is not smart enough to
-automatically see that each time we use the macro, two new macros are
-defined.  We can specify this information in a style hook file.
-
-@lisp
-;;; macro.el --- Special code for my own macro file.
-
-;;; Code:
-
-(defvar TeX-newmacro-regexp

-
-(defvar TeX-auto-multi nil
-  "Temporary for parsing \\newmacro definitions.")
-
-(defun TeX-macro-cleanup ()
-  "Move symbols from `TeX-auto-multi' to `TeX-auto-symbol'."

-;;; macro.el ends here
-@end lisp
-
-When this file is first loaded, it adds a new entry to
-@code{TeX-newmacro-regexp}, and defines a function to be called before
-the parsing starts, and one to be called after the parsing is done.  It
-also declares a variable to contain the data collected during parsing.
-Finally, it adds a style hook which describes the @samp{newmacro} macro,
-as we have seen it before.
-
-So the general strategy is: Add a new entry to @code{TeX-newmacro-regexp}.
-Declare a variable to contain intermediate data during parsing.  Add hook
-to be called before and after parsing.  In this case, the hook before
-parsing just initializes the variable, and the hook after parsing
-collects the data from the variable, and adds them to the list of symbols
-found.
-
-@defvar TeX-auto-regexp-list
-List of regular expressions matching @TeX{} macro definitions.
-
-The list has the following format ((@var{regexp} @var{match} @var{table}) @dots{}), that
-is, each entry is a list with three elements.
-
-@var{regexp}.  Regular expression matching the macro we want to parse.
-
-@var{match}.  A number or list of numbers, each representing one
-parenthesized subexpression matched by @var{regexp}.
-
-@var{table}.  The symbol table to store the data.  This can be a function, in
-which case the function is called with the argument @var{match}.  Use
-@code{TeX-match-buffer} to get match data.  If it is not a function, it
-is presumed to be the name of a variable containing a list of match
-data.  The matched data (a string if @var{match} is a number, a list of
-strings if @var{match} is a list of numbers) is put in front of the table.

-@node Texinfo mode
-@appendixsec Features specific to @AUCTeX{}'s Texinfo major mode
-
-@AUCTeX{} includes a major mode for editting Texinfo files.  This major
-mode is not the same mode as the native Texinfo mode (@pxref{Texinfo Mode,,,
-texinfo,Texinfo}) of Emacs, although they have the same name.  However,
-@AUCTeX{} still relies on a number of functions from the native Texinfo
-mode.
-
-The following text describes which functionality is offered by @AUCTeX{}
-and which by the native Texinfo mode.  This should enable you to decide
-when to consult the @AUCTeX{} manual and when the manual of the native
-mode.  And in case you are a seasoned user of the native mode, the
-information should help you to swiftly get to know the
-@AUCTeX{}-specific commands.

-@end menu
-
-@node Exploiting
-@appendixsubsec How @AUCTeX{} and the native mode work together
-
-In a nutshell the split between @AUCTeX{} Texinfo mode, and native
-Texinfo mode is as follows:
-
-@itemize
-@item
-Most of the editing (environment creation, commenting, font command
-insertions) and/or processing commands (e.g.@: compiling or printing)
-which are available in other @AUCTeX{} modes are also handled by
-@AUCTeX{} in Texinfo mode.
-
-@item
-Texinfo-related features (e.g.@: info node linkage or menu creation) rely
-on the commands provided by the native Texinfo mode.  @AUCTeX{} provides
-the key bindings to reach these functions, keeping the same keys as in
-native Texinfo whenever possible, or similar ones otherwise.
-@end itemize
-
-@node Superseding
-@appendixsubsec Where the native mode is superseded
-
-This section is directed to users of the native Texinfo mode switching
-to @AUCTeX{}.  It follows the summary of the native mode
-(@pxref{Texinfo Mode Summary,,,texinfo,Texinfo}) and lists which of its commands
-are no longer of use.
-
-@table @asis
-@item Insert commands
-In the native Texinfo mode, frequently used Texinfo commands can be
-inserted with key bindings of the form @kbd{C-c C-c @var{k}} where
-@var{k} differs for each Texinfo command; @kbd{c} inserts @code{@@code},
-@kbd{d} inserts @code{@@dfn}, @kbd{k} @code{@@kbd}, etc.
-
-In @AUCTeX{} commands are inserted with the key binding @kbd{C-c C-m}
-instead which prompts for the macro to be inserted.  For font selection
-commands (like @code{@@b}, @code{@@i}, or @code{@@emph}) and a few related ones (like @code{@@var},
-@code{@@key} or @code{@@code}) there are bindings which insert the respective macros
-directly.  They have the form @kbd{C-c C-f @var{k}} or @kbd{C-c C-f
-C-@var{k}} and call the function @code{TeX-font}.  Type @kbd{C-c C-f
-@key{RET}} to get a list of supported commands.
-
-Note that the prefix argument is not handled the same way by @AUCTeX{}.
-Note also that the node insertion command from the native mode
-(@code{texinfo-insert-@@node}) can still accessed from the Texinfo menu
-in @AUCTeX{}.
-
-@item Insert braces
-In @AUCTeX{} braces can be inserted with the same key binding as in the
-native Texinfo mode: @kbd{C-c @{}.  But @AUCTeX{} uses its own function
-for the feature: @code{TeX-insert-braces}.
-
-@item Insert environments
-The native Texinfo mode does not insert full environments.  Instead, it
-provides the function @code{texinfo-insert-@@end} (mapped to @kbd{C-c
-C-c e}) for closing an open environment with a matching @code{@@end} statement.
-
-In @AUCTeX{} you can insert full environments, i.e.@: both the opening and
-closing statements, with the function @code{Texinfo-environment} (mapped
-to @kbd{C-c C-e}).
-
-@item Format info files with makeinfo and @TeX{}
-In the native Texinfo mode there are various functions and bindings to
-format a region or the whole buffer for info or to typeset the
-respective text.  For example, there is @code{makeinfo-buffer} (mapped
-to @kbd{C-c C-m C-b}) which runs @samp{makeinfo} on the buffer or there
-is @code{texinfo-tex-buffer} (mapped to @kbd{C-c C-t C-b}) which runs
-@TeX{} on the buffer in order to produce a @acronym{DVI} file.
-
-In @AUCTeX{} different commands for formatting or typesetting can be
-invoked through the function @code{TeX-command-master} (mapped to
-@kbd{C-c C-c}).  After typing @kbd{C-c C-c}, you can select the desired
-command, e.g @samp{Makeinfo} or @samp{TeX}, through a prompt in the mini
-buffer.  Note that you can make, say @samp{Makeinfo}, the default by
-adding this statement in your init file:
-
-@lisp
-(add-hook 'Texinfo-mode-hook 
-          (lambda () (setq TeX-command-default "Makeinfo")))
-@end lisp
-
-Note also that @kbd{C-c C-c Makeinfo @key{RET}} is not completely
-functionally equivalent to @code{makeinfo-buffer} as the latter will
-display the resulting info file in Emacs, showing the node corresponding
-to the position in the source file, just after a successful compilation.
-This is why, while using @AUCTeX{}, invoking @code{makeinfo-buffer}
-might still be more convenient.
-
-Note also that in the case of a multifile document, @kbd{C-c C-c} in
-@AUCTeX{} will work on the whole document (provided that the file
-variable @code{TeX-master} is set correctly), while
-@code{makeinfo-buffer} in the native mode will process only the current
-buffer, provided at the @code{@@setfilename} statement is provided.
-
-@item Produce indexes and print
-The native Texinfo mode provides the binding @kbd{C-c C-t C-i}
-(@code{texinfo-texindex}) for producing an index and the bindings
-@kbd{C-c C-t C-p} (@code{texinfo-tex-print}) and @kbd{C-c C-t C-q}
-(@code{tex-show-print-queue}) for printing and showing the printer
-queue.  These are superseded by the respective commands available
-through @kbd{C-c C-c} (@code{TeX-command-master}) in @AUCTeX{}: @samp{Texindex},
-@samp{Print}, and @samp{Queue}.
-
-@item Kill jobs
-The command @kbd{C-c C-t C-k} (@code{tex-kill-job}) in the native mode
-is superseded by @kbd{C-c C-k} (@code{TeX-kill-job}) in @AUCTeX{}.
-@end table
-
-@node Mapping
-@appendixsubsec Where key bindings are mapped to the native mode
-
-This node follows the native Texinfo mode summary (@pxref{Texinfo Mode
-Summary,,,texinfo,Texinfo}) and lists only those commands to which @AUCTeX{}
-provides a keybinding.
-
-Basically all commands of the native mode related to producing menus and
-interlinking nodes are mapped to same or similar keys in @AUCTeX{},
-while a few insertion commands are mapped to @AUCTeX{}-like keys.
-
-@table @asis
-
-@item @code{@@item} insertion
-The binding @kbd{C-c C-c i} for the insertion of @code{@@item} in the
-native mode is mapped to @kbd{M-@key{RET}} or @kbd{C-c C-j} in
-@AUCTeX{}, similar to other @AUCTeX{} modes.
-
-@item @code{@@end} insertion
-The binding @kbd{C-c C-c e} for closing a @code{@@@var{foo}} command by
-a corresponding @code{@@end @var{foo}} statement in the native mode is
-mapped to @kbd{C-c ]} in @AUCTeX{}, similar to other @AUCTeX{} modes.
-
-@item Move out of balanced braces
-The binding @kbd{C-c @}} (@code{up-list}) is available both in the native
-mode and in @AUCTeX{}.  (This is because the command is not implemented
-in either mode but a native Emacs command.)  However, in @AUCTeX{}, you
-cannot use @kbd{C-c ]} for this, as it is used for @code{@@end} insertion.
-
-@item Update pointers
-The bindings @kbd{C-c C-u C-n} (@code{texinfo-update-node}) and @kbd{C-c
-C-u C-e} (@code{texinfo-every-node-update}) from the native mode are
-available in @AUCTeX{} as well.
-
-@item Update menus
-The bindings @kbd{C-c C-u m} (@code{texinfo-master-menu}), @kbd{C-c C-u
-C-m} (@code{texinfo-make-menu}), and @kbd{C-c C-u C-a}
-(@code{texinfo-all-menus-update}) from the native mode are available in
-@AUCTeX{} as well.  The command @code{texinfo-start-menu-description},
-bound to @kbd{C-c C-c C-d} in the native mode, is bound to @kbd{C-c C-u
-C-d} in @AUCTeX{} instead.
-@end table
-
-@node Unbinding
-@appendixsubsec Which native mode key bindings are missing
-
-The following commands from the native commands might still be useful
-when working with @AUCTeX{}, however, they are not accessible with a
-key binding any longer.
-
-@table @asis
-@item @code{@@node} insertion
-The node insertion command, mapped to @kbd{C-c C-c n} in the native
-mode, is not mapped to any key in @AUCTeX{}.  You can still access it
-through the Texinfo menu, though.  Another alternative is to use the
-@kbd{C-c C-m} binding for macro insertion in @AUCTeX{}.
-
-@item Show the section structure
-The command @code{texinfo-show-structure} (@kbd{C-c C-s}) from the
-native mode does not have a key binding in @AUCTeX{}.  The binding is
-used by @AUCTeX{} for sectioning.

-@AUCTeX{} now requires GNU Emacs 25.1 or higher.
-
-@item
-@AUCTeX{} tracks the change in Emacs where initial inputs in the
-minibuffer during queries are getting phased out.  Queries for the
-mandatory arguments of macros and environments are adjusted where
-applicable.  The value which will be used after hitting @kbd{RET} without

-In math environments @samp{gather}, @samp{gather*}, @samp{gathered},
-@samp{multline} and @samp{multline*}, fill commands such as @kbd{M-q} and
-@kbd{C-c C-q C-e} are disabled.  This sorts out the inconsistency between
-those and @samp{equation}, @samp{displaymath} environments, in latter of
-which filling is already disabled.
-
-If you want filling in such environments, customize
-@code{LaTeX-indent-environment-list} to remove them.
-
-Auto fill continues to work in such environment anyway.
-
-In addition, @AUCTeX{} adds support of alignment at @samp{&} sign in
-@samp{align}-like environments such as @samp{alignat}, @samp{aligned} and
-so on, as well as @samp{matrix}-like environments such as @samp{pmatrix},
-@samp{bmatrix} and so on.
-
-@item
-Now two commands @samp{Texindex} and @samp{Texi2dvi} are available when
-you type @kbd{C-c C-c} in Texinfo mode.  The command @samp{Texindex} runs
-@command{texindex} on index files and @samp{Texi2dvi} runs
-@command{pdftexi2dvi} or @command{texi2dvi} according to the value of
-@code{TeX-PDF-mode}.
-
-So you can typeset Texinfo documents into @acronym{PDF} or @acronym{DVI}
-format from within @AUCTeX{}.
-
-@item
-@AUCTeX{}'s own help messages for @LaTeX{} errors are now shown only for
-@LaTeX{} runs.  @AUCTeX{} shows raw error/warning messages found in
-@file{.log} files for runs of formats other than @LaTeX{}, such as plain
-@TeX{}, @ConTeXt{} and Texinfo, as it does even for @LaTeX{} runs when it
-can't find a matching entry in its own help message catalogue.
-
-Due to this change, customize option @code{TeX-error-description-list} can
-no longer have a fallback entry that matches any error.  If your
-customized value includes such entry, typically @samp{(".*" . "No help
-available")}, please remove it.

-uses these functions, use @code{split-string} and @code{assoc-string}
-instead.
-
-@item
-The function @code{TeX-read-key-val} now accepts a function call as second
-argument.  This change should help @AUCTeX{} style writers who use
-@code{TeX-arg-key-val} and have to deal with dynamic key-values.  Example
-of usage:
-@lisp

-A new method is implemented in @previewlatex{} to adjust the foreground
-colors of generated images to those of Emacs, when the @LaTeX{} command
-produces @acronym{PDF}.  The traditional method became invalid because
-of the change introduced in Ghostscript 9.27.  Unfortunately, the new
-method doesn't work due to a bug in Ghostscript 9.27 and is valid only
-for Ghostscript > 9.27.  There is also a fallback method for gs 9.27
-users which displays plain ``black on white'' images.  For successful
-function of @previewlatex{}, the users are encouraged to set up the new

-The way the option @code{TeX-record-buffer} is used was corrected.  It

-

-A former customize option @code{japanese-TeX-command-list} is removed.
-Use @code{japanese-TeX-engine-default}, or if it's really necessary,
-customize @code{TeX-command-list} directly if the task which the option
-used to carry is required.
-
-@item
-Support for standard @LaTeX{} without e-@TeX{} extension is now very
-limited.  It doesn't work if raw @TeX{} code is put on the command line
-to invoke @command{latex} command.  It also fails for region compilation (@kbd{C-c
-C-r} and so on) with documents of non-ascii file name.  In addition, it
-no longer works with @previewlatex{}.  We consider this incompatibility
-is permissible because e-@TeX{} extension is enabled for standard
-@LaTeX{} by default long ago.  @LaTeX{} variants such as Xe@LaTeX{} and
-Lua@LaTeX{} are not affected.
-
-@item
-Key binds in Texinfo mode are improved.  Typing @kbd{$}, @kbd{^},
-@kbd{_} and @kbd{\} now just self-inserts without pointless side effects
-in Texinfo mode.
-
-In addition, the option @code{TeX-electric-escape} is now effective in
-Texinfo mode.  When it is enabled, typing @kbd{@@} will invoke
-@code{TeX-electric-macro} offering completion in similar style with
-other @TeX{} modes of @AUCTeX{}.
-
-@item
-Fontification support for @samp{biblatex} package is improved and

-lists, at least 2 mandatory arguments are fontified.
-

-Support for column specifiers @samp{w} and @samp{W} provided by
-@samp{array} package is added to @file{array.el}.  The correct counting

-@AUCTeX{} can put and parse labels in optional argument of environments.
-Inserting labels is done by new function

-typesetting environments, e.g.@: @samp{lstlisting} environment provided by
-@samp{listings} package.  @code{LaTeX-listing-label} defaults to
-@code{lst:}.  Parsing of labels for later referencing relies on two
-requirements:
-@enumerate
-@item
-Label should come as last key-value argument, and
-@item
-label must be enclosed in braces, e.g.
-@example
-\begin@{lstlisting@}[caption=Some Caption,label=@{lst:foo@}]
-...
-\end@{lstlisting@}
-@end example

-The function @code{LaTeX-label} now takes a second optional argument
-@code{NO-INSERT}.  When non-@code{nil}, @code{LaTeX-label} reads a label
-and returns it as a string.  This argument is also passed to any
-function bound to @code{LaTeX-label-function} (see next item).
-
-@item
-@strong{Incompatible change:} The signature for the function passed with

-
-@item
-Filling and indentation in XEmacs with @previewlatex{} and activated
-previews lead to the insertion of whitespace before multi-line previews.
-@AUCTeX{} now contains facilities to prevent this problem.
-
-@item
-If @code{TeX-master} is set to @code{t}, @AUCTeX{} will now query for a

-@end ifset
-
-@c We should switch to sectioning commands instead of items when this
-@c list grows.  Keep in mind to formulate short questions because
-@c section headings will not be broken in contrast to items.
-@enumerate
-@item
-Something is not working correctly.  What should I do?
-
-Well, you might have guessed it, the first place to look is in the
-available documentation packaged with @AUCTeX{}.  This could be the
-release notes (in the @file{RELEASE} file) or the news section of the
-manual in case you are experiencing problems after an upgrade, the
-@file{INSTALL} file in case you are having problems with the
-installation, the section about bugs in the manual in case you
-encountered a bug or the relevant sections in the manual for other
-related problems.
-
-If this did not help, you can send a bug report to the @AUCTeX{} bug
-reporting list by using the command @kbd{M-x TeX-submit-bug-report @key{RET}}.
-But before you do this, you can try to get more information about the
-problem at hand which might also help you locate the cause of the error
-yourself.
-
-First, you can try to generate a so-called backtrace which shows the
-functions involved in a program error.  In order to do this, start Emacs
-with the command line @samp{emacs --debug-init} and/or put the line
-
-@lisp
-(setq debug-on-error t)
-@end lisp
-
-as the first line into your init file.  After Emacs has started, you can
-load a file which triggers the error and a new window should pop up
-showing the backtrace.  If you get such a backtrace, please include it
-in the bug report.
-
-Second, you can try to figure out if something in your personal or site
-configuration triggers the error by starting Emacs without such
-customizations.  You can do this by invoking Emacs with the following
-command line, depending on the installation scheme of @AUCTeX{} and your
-@acronym{OS}:
-@itemize
-@item
-If you installed @AUCTeX{} from @acronym{ELPA}, use @samp{emacs -q
--no-site-file --eval "(progn (setq package-load-list '((auctex t)))
-(package-initialize))"}.  The @option{--eval} option activates only
-@AUCTeX{} among all installed @acronym{EPLA} packages.
-@item
-If you installed @AUCTeX{} via traditional
-@command{configure}--@command{make} scheme, use @samp{emacs -q
--no-site-file -l auctex}.  The @option{-l} option loads @file{auctex.el}
-which you normally do in your init file.
-@item
-In both above cases, use @samp{runemacs} instead of @samp{emacs} on
-windows.
-@end itemize
-
-After you
-have started Emacs like this, you can load the file triggering the
-error.  If everything is working now, you know that you have to search
-either in the site configuration file or your personal init file for
-statements related to the problem.
-
-@item
-What versions of Emacs are supported?
-
-@AUCTeX{} was tested with @w{GNU Emacs 25.1}.  Older versions may work but
-are unsupported.
-
-@item
-What should I do when @command{./configure} does not find programs like @command{latex}?
-
-This is problem often encountered on Windows.  Make sure that the
-@env{PATH} environment variable includes the directories containing the
-relevant programs, as described in
-@ifset rawfile
-the file @file{INSTALL.windows}
-@end ifset
-@ifclear rawfile
-@ref{Installation under MS Windows,,,auctex,the @AUCTeX{} manual}.
-@end ifclear
-
-@item
-Why doesn't the completion, style file, or multifile stuff work?
-
-It must be enabled first, insert this in your init file:
-
-@lisp
-(setq-default TeX-master nil)
-(setq TeX-parse-self t)
-(setq TeX-auto-save t)
-@end lisp
-
-Read also the chapters about parsing and multifile documents in the
-manual.
-@ifclear rawfile
-@xref{Parsing Files} and @ref{Multifile}.
-@end ifclear
-
-@item
-Why doesn't @code{TeX-save-document} work?
-
-@code{TeX-check-path} has to contain "@file{./}" somewhere.
-
-@item
-Why is the information in @file{foo.tex} forgotten when I save
-@file{foo.bib}?
-
-For various reasons, @AUCTeX{} ignores the extension when it stores
-information about a file, so you should use unique base names for your
-files.  E.g.@: rename @file{foo.bib} to @file{foob.bib}.
-
-@item
-Why doesn't @AUCTeX{} signal when processing a document is done?
-
-If the message in the minibuffer stays "Type `C-c C-l' to display
-results of compilation.", you probably have a misconfiguration in your
-init file (@file{.emacs}, @file{init.el} or similar).  To track this
-down either search in the @samp{*Messages*} buffer for an error message
-or put @code{(setq debug-on-error t)} as the first line into your init
-file, restart Emacs and open a @LaTeX{} file.  Emacs will complain
-loudly by opening a debugging buffer as soon as an error occurs.  The
-information in the debugging buffer can help you find the cause of the
-error in your init file.
-
-@item
-Why does @code{TeX-next-error} (@kbd{C-c `}) fail?
-
-If @code{TeX-file-line-error} is set to nil (not the default), these
-sort of failures might be related to the the fact that when writing the
-log file, @TeX{} puts information related to a file, including error
-messages, between a pair of parentheses.  In this scenario @AUCTeX{}
-determines the file where the error happened by parsing the log file and
-counting the parentheses.  This can fail when there are other,
-unbalanced parentheses present.
-
-Activating so-called @samp{file:line:error} messages for the log file usually
-solves this issue, as these kind of messages are are easier to parse;
-however, they may lack some details.  Activation can be done either in
-the configuration of your @TeX{} system (consult its manual to see where
-this is) or by simply keeping the variable @code{TeX-file-line-error} to
-the default value of non-nil.
-
-@item
-What does @samp{AUC} stand for?
-
-@AUCTeX{} came into being at Aalborg University in Denmark.  Back then
-the Danish name of the university was Aalborg Universitetscenter; @samp{AUC}
-for short.

-PREAMBLE
-
-The purpose of this License is to make a manual, textbook, or other
-functional and useful document @dfn{free} in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-
-This License is a kind of ``copyleft'', which means that derivative
-works of the document must themselves be free in the same sense.  It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-
-We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does.  But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book.  We recommend this License
-principally for works whose purpose is instruction or reference.
-
-@item
-APPLICABILITY AND DEFINITIONS
-
-This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License.  Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein.  The ``Document'', below,
-refers to any such manual or work.  Any member of the public is a
-licensee, and is addressed as ``you''.  You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-
-A ``Modified Version'' of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-
-A ``Secondary Section'' is a named appendix or a front-matter section
-of the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document's overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject.  (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.)  The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-
-The ``Invariant Sections'' are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License.  If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant.  The Document may contain zero
-Invariant Sections.  If the Document does not identify any Invariant
-Sections then there are none.
-
-The ``Cover Texts'' are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License.  A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-
-A ``Transparent'' copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters.  A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text.  A copy that is not ``Transparent'' is called ``Opaque''.
-
-Examples of suitable formats for Transparent copies include plain
-@sc{ascii} without markup, Texinfo input format, La@TeX{} input
-format, @acronym{SGML} or @acronym{XML} using a publicly available
-@acronym{DTD}, and standard-conforming simple @acronym{HTML},
-PostScript or @acronym{PDF} designed for human modification.  Examples
-of transparent image formats include @acronym{PNG}, @acronym{XCF} and
-@acronym{JPG}.  Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, @acronym{SGML} or
-@acronym{XML} for which the @acronym{DTD} and/or processing tools are
-not generally available, and the machine-generated @acronym{HTML},
-PostScript or @acronym{PDF} produced by some word processors for
-output purposes only.
-
-The ``Title Page'' means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page.  For works in
-formats which do not have any title page as such, ``Title Page'' means
-the text near the most prominent appearance of the work's title,
-preceding the beginning of the body of the text.
-
-The ``publisher'' means any person or entity that distributes copies
-of the Document to the public.
-
-A section ``Entitled XYZ'' means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language.  (Here XYZ stands for a
-specific section name mentioned below, such as ``Acknowledgements'',
-``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
-of such a section when you modify the Document means that it remains a
-section ``Entitled XYZ'' according to this definition.
-
-The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document.  These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.
-
-@item
-VERBATIM COPYING
-
-You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License.  You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute.  However, you may accept
-compensation in exchange for copies.  If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-
-You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-
-@item
-COPYING IN QUANTITY
-
-If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document's license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover.  Both covers must also clearly and legibly identify
-you as the publisher of these copies.  The front cover must present
-the full title with all words of the title equally prominent and
-visible.  You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-
-It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-
-@item
-MODIFICATIONS
-
-You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it.  In addition, you must do these things in the Modified Version:
-
-@enumerate A
-@item
-Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document).  You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-@item
-List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has fewer than five),
-unless they release you from this requirement.
-
-@item
-State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-@item
-Preserve all the copyright notices of the Document.
-
-@item
-Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-@item
-Include, immediately after the copyright notices, a license notice
-giving the public permission to use the Modified Version under the
-terms of this License, in the form shown in the Addendum below.
-
-@item
-Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document's license notice.
-
-@item
-Include an unaltered copy of this License.
-
-@item
-Preserve the section Entitled ``History'', Preserve its Title, and add
-to it an item stating at least the title, year, new authors, and
-publisher of the Modified Version as given on the Title Page.  If
-there is no section Entitled ``History'' in the Document, create one
-stating the title, year, authors, and publisher of the Document as
-given on its Title Page, then add an item describing the Modified
-Version as stated in the previous sentence.
-
-@item
-Preserve the network location, if any, given in the Document for
-public access to a Transparent copy of the Document, and likewise
-the network locations given in the Document for previous versions
-it was based on.  These may be placed in the ``History'' section.
-You may omit a network location for a work that was published at
-least four years before the Document itself, or if the original
-publisher of the version it refers to gives permission.
-
-@item
-For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
-the Title of the section, and preserve in the section all the
-substance and tone of each of the contributor acknowledgements and/or
-dedications given therein.
-
-@item
-Preserve all the Invariant Sections of the Document,
-unaltered in their text and in their titles.  Section numbers
-or the equivalent are not considered part of the section titles.
-
-@item
-Delete any section Entitled ``Endorsements''.  Such a section
-may not be included in the Modified Version.
-
-@item
-Do not retitle any existing section to be Entitled ``Endorsements'' or
-to conflict in title with any Invariant Section.
-
-@item
-Preserve any Warranty Disclaimers.
-@end enumerate
-
-If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant.  To do this, add their titles to the
-list of Invariant Sections in the Modified Version's license notice.
-These titles must be distinct from any other section titles.
-
-You may add a section Entitled ``Endorsements'', provided it contains
-nothing but endorsements of your Modified Version by various
-parties---for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-
-You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version.  Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity.  If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-
-The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-
-@item
-COMBINING DOCUMENTS
-
-You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-
-The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy.  If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-
-In the combination, you must combine any sections Entitled ``History''
-in the various original documents, forming one section Entitled
-``History''; likewise combine any sections Entitled ``Acknowledgements'',
-and any sections Entitled ``Dedications''.  You must delete all
-sections Entitled ``Endorsements.''
-
-@item
-COLLECTIONS OF DOCUMENTS
-
-You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-
-You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-
-@item
-AGGREGATION WITH INDEPENDENT WORKS
-
-A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an ``aggregate'' if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation's users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-
-If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document's Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-
-@item
-TRANSLATION
-
-Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections.  You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers.  In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-
-If a section in the Document is Entitled ``Acknowledgements'',
-``Dedications'', or ``History'', the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-
-@item
-TERMINATION
-
-You may not copy, modify, sublicense, or distribute the Document
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense, or distribute it is void, and
-will automatically terminate your rights under this License.
-
-However, if you cease all violation of this License, then your license
-from a particular copyright holder is reinstated (a) provisionally,
-unless and until the copyright holder explicitly and finally
-terminates your license, and (b) permanently, if the copyright holder
-fails to notify you of the violation by some reasonable means prior to
-60 days after the cessation.
-
-Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, receipt of a copy of some or all of the same material does
-not give you any rights to use it.
-
-@item
-FUTURE REVISIONS OF THIS LICENSE
-
-The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation License from time to time.  Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.  See
-@uref{https://www.gnu.org/licenses/}.
-
-Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License ``or any later version'' applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation.  If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation.  If the Document
-specifies that a proxy can decide which future versions of this
-License can be used, that proxy's public statement of acceptance of a
-version permanently authorizes you to choose that version for the
-Document.

-@item
-RELICENSING
-
-``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
-World Wide Web server that publishes copyrightable works and also
-provides prominent facilities for anybody to edit those works.  A
-public wiki that anybody can edit is an example of such a server.  A
-``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
-site means any set of copyrightable works thus published on the MMC
-site.
-
-``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
-license published by Creative Commons Corporation, a not-for-profit
-corporation with a principal place of business in San Francisco,
-California, as well as future copyleft versions of that license
-published by that same organization.
-
-``Incorporate'' means to publish or republish a Document, in whole or
-in part, as part of another Document.
-
-An MMC is ``eligible for relicensing'' if it is licensed under this
-License, and if all works that were first published under this License
-somewhere other than this MMC, and subsequently incorporated in whole
-or in part into the MMC, (1) had no cover texts or invariant sections,
-and (2) were thus incorporated prior to November 1, 2008.
-
-The operator of an MMC Site may republish an MMC contained in the site
-under CC-BY-SA on the same site at any time before August 1, 2009,
-provided the MMC is eligible for relicensing.

-@heading ADDENDUM: How to use this License for your documents
-
-To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and
-license notices just after the title page:
-
-@smallexample
-@group
-  Copyright (C)  @var{year}  @var{your name}.
-  Permission is granted to copy, distribute and/or modify this document
-  under the terms of the GNU Free Documentation License, Version 1.3
-  or any later version published by the Free Software Foundation;
-  with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
-  Texts.  A copy of the license is included in the section entitled ``GNU
-  Free Documentation License''.
-@end group
-@end smallexample
-
-If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
-replace the ``with@dots{}Texts.''@: line with this:
-
-@smallexample
-@group
-    with the Invariant Sections being @var{list their titles}, with
-    the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
-    being @var{list}.
-@end group
-@end smallexample
-
-If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
-If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License,
-to permit their use in free software.

-
-@item
-@code{LaTeX-math-mode} no longer works on Emacs 18 or older Lucid
-versions.  This change allowed me to unbundle @file{min-map.el}.
-
-@item
-Made @kbd{C-c C-e} more robust, especially when applied on an empty

-
-@item
-@kbd{C-c C-m section RET} and @kbd{M-@key{tab}} should work now in

-to @key{/}, and @samp{wedge}, @samp{vee}, and @samp{neg} installed on
-@key{&}, @kbd{|}, and @kbd{!} to make writing logic easier for C
-programmers.
-
-@item
-Renamed @file{auc-tex.el} to @file{auc-old.el} to make it less likely
-that new users load it by mistake.
-
-@item
-Changed name of @file{easymenu.el} to @file{auc-menu.el} to avoid
-conflict with RMS's version.  Updated it to handle the Lucid
-@code{:keys} keyword argument.  Defines a popup menu for both FSF and
-Lucid emacs, although it is only installed in Lucid Emacs.  Added David
-Aspinall's @samp{<da@@dcs.edinburgh.ac.uk>} patch to handle an empty
-menu bar under Lucid Emacs.  The interface is still a superset of
-@file{easymenu.el}.  This version should no longer prevent the sharing
-of byte compiled files between FSF and Lucid emacs.

-generated from chapters of this manual, to ensure they stay in sync.
-
-@item
-@kbd{M-@key{tab}} will now complete some macro arguments in addition to
-macro names.  In particular, if you press @kbd{M-@key{tab}} after
-@samp{\cite@{} or @samp{\ref@{} you will get completion for bibitems and
-labels, respectively.
-
-@item
-Merged a number of files.  The major files are now @file{tex.el} for

-
-@item
-Unbundled @file{outln-18.el}.  Users of Emacs 18 or Lucid Emacs 19.9 or

-if they want the outline commands to work.
-
-@item
-No longer bind @kbd{C-c @key{tab}} to @code{TeX-complete-symbol}.  Use
-@kbd{M-@key{tab}} instead.
-
-@item
-Cleaned up the parser and parameterizedd it.  Now you can add now types
-of information to be maintained by the parser simply by calling
-@code{TeX-auto-add-type}.  You still need to install the regexps with
-@code{TeX-auto-add-regexp}.

-@kbd{C-u C-c C-e} will now modify the current environment instead of

-The external commands will now insert there output @emph{before} point
-in the output buffers.  This allows you to follow the progress by
-putting point at the end of the file.  Suggested by Jak Kirman

-
-@item
-When invoking an external command from a menu, the document will be
-automatically saved. 
-
-@item
-There are now a printer menu for emacs 19.
-
-@item
-Redesigned dependency checking.  Now only checks dependencies for files
-loaded in the current emacs session.  This is much faster, but will not
-catch files that are edited outside this emacs session, or files edited
-in killed buffers.  @strong{@code{TeX-check-path} must at least contain
-@file{.} for saving to work}.  If you have set @samp{TeX-check-path}
-in your @file{.emacs} file, remove it.  The default value is fast enough
-now.
-
-@item
-New variable @code{TeX-save-query} control if AUC @TeX{} will query you
-for each modified buffer when you save the document.  Set it to nil to
-get rid of these questions.  Setting this variable also affect the
-automatic saving of the document that happens each time you start an
-external command.
-
-@item
-New command @code{TeX-save-document} will save all files in the current
-document, i.e. the document associated with the current buffer.
-
-@item 
-Cleaned up all minor modes, also made them use @file{min-map.el} or
-@file{min-mode.el} instead of @file{min-bind.el}.
-
-@item
-Cleaned up release management.
-
-@item
-AUC TeX will not longer be confused when you rewrite a file under a new

-
-@item
-Lots of code cleanup, involving reformatting the source and renaming all
-@samp{-hook} variables and functions to conform with the Emacs 19
-guidelines. 
-

-Can now parse Japanese characters in labels and macros when you use
-Japanese @TeX{}.  Thanks to Shinji Kobayashi
-@samp{<koba@@flab.fujitsu.co.jp>}.
-

-Made it safe to quit when AUC @TeX{} asks for the name of the master
-file.  It will simply assume the file itself is the master, and continue
-without inserting any file local variables.
-

-Support for @code{epsf} and @code{psfig} style files.  Thanks to Marc

-Support for @LaTeX{}info.  Thanks to Marc Gemis
-@samp{<makke@@wins.uia.ac.be>}.
-
-@item
-Only examine the first 10000 bytes to find out what @TeX{} mode to use.
-
-@item 
-Added @code{TeX-submit-bug-report} command to submit bug reports.  It
-uses the @file{reporter.el} distributed with SuperCite, so it may not be
-available in some Emacs 18 installations.
-
-@item
-Speeded up parsing significantly by using a simpler regexp.
-
-@item
-Added variable @code{TeX-auto-untabify}.  Set it to nil to prevent
-untabifying the buffer when it is saved.  Several people wanted this. 
-
-@item
-Changed defaults to @emph{not} do any automatic parsing, nor prompt for
-a master file.  @xref{Parsing Files}, @ref{Multifile}, for information
-about how ot correct this.  In short, insert the following in your
-@file{.emacs} file.
-
-@lisp
-(setq TeX-auto-save t)
-(setq TeX-parse-self t)
-(setq-default TeX-master nil)
-@end lisp
-
-@item
-Some grammatical fixes to the @file{PROBLEMS} file.  Thanks to Lawrence
-R. Dodd @samp{<dodd@@roebling.poly.edu>}.
-
-@item
-No longer install a separate @code{outline-minor-mode} by default, as
-the FSF Emacs 19.19 @code{outline-minor-mode} is adequate.  The included
-file @file{outln-18.el} emulates the FSF Emacs 19.19 mode under Emacs 18.
-
-The FSF Emacs 19.19 @code{outline-minor-mode} use the @kbd{C-c} prefix
-instead of @kbd{C-c C-o} by default, and does not bind as many keys as
-the @code{outline-minor-mode} distributed with earlier versions of AUC
-@TeX{} did.  You can get the keybindings back together with other
-goodies by inserting
-@example
-(require 'out-xtra)
-@end example
-in your @file{.emacs} file.  @file{out-xtra.el} will probably be
-unbundled from AUC @TeX{} in the future.

-buffer manipulation commands in tex-buf.el.  To use the new bindings,
-load @file{tex-init.el} instead of @file{auc-tex.el}.
-
-The file @file{auc-tex.el} is still available and implements the old
-keybindings on top of the new code.
-
-Print out the reference card (@file{doc/tex-ref.tex}) to see the new
-bindings.  
-
-@item
-Completely redesigned the buffer handling. 
-
-No part of the interface or the customization variables remain the same,
-unless you use the compatibility functions in @file{auc-tex.el}.  In
-that case the interactive commands remain similar in spirit, but the
-customization interface is still changed. 
-
-The file @file{tex-buf.el} has been completely rewritten, and there are
-major cleanup in @file{tex-dbg.el}, however the basic functionality
-remains the same in this file.  The code for both @file{tex-buf.el} and
-@file{tex-dbg.el} should be much simpler now and easier to extent.
-
-@file{auc-tex.el} and @file{tex-site.el} was updated to support the new
-interface.  I actually believe the moral equivalent to @code{TeX-region}
-to work now @t{:-)}, at least I understand the code now.
-
-The two major functions are now @code{TeX-command-master} and
-@code{TeX-command-region}.  Each function will prompt you for the
-command to execute.  AUC @TeX{} will make an educated guess on what
-command you want to run, and make that the default.  The available
-commands are defined in the variable @code{TeX-command-list}.
-
-@code{TeX-command-master} will run the specified command on the buffers
-master file.  You can have one command running for each master file.
-@code{TeX-command-region} will run the specified command on the current
-region, getting the header on trailer from the master file.  
-
-You can have exactly one region command running, independent on how many
-master file commands that are running.  Commands that operate on the
-active process (like @code{TeX-next-error}) will chose the process
-associated with buffers master file, unless the last region process is
-more recent than all master file processes.
-
-AUC @TeX{} now insist on knowing the master file for a buffer.  If you
-do not specify it in the file variable section, and it is not obviously
-a master file itself, it will ask you.  It will also add the master file
-name to the file variables, unless you disable this feature by setting
-@code{TeX-add-local} to nil.  Furthermore, it will convert @samp{%%
-Master:} lines to file variables, unless you disable it by setting
-@code{TeX-convert-master} to nil.
-@vindex TeX-convert-master
-
-Functionality removed (for now, it might appear again latter) include
-all other functions to start a command (e.g. @code{LaTeX-BibTeX}), and
-alternative ways to specify headers and trailers.  The only place to get
-the header and trailer is from the master file (I can easily change
-that, if anyone have such needs).
-
-@item
-Style specific code isolated.
-
-You can now add style specific information to AUC TeX by writing a
-style file somewhere in TeX-style-path.
-
-The main code is now organized around this principle.
-
-@item
-Automatically generate style files.
-
-AUC @TeX{} can now automatically extract information from a @TeX{} file,
-and will do this when you save a buffer.
-
-@item
-Sli@TeX{} mode.
-
-Just like @LaTeX{} mode, except that the default command to format run
-on the buffer is @samp{slitex}.
-
-@item
-@code{LaTeX-section} completely general.
-
-Rewrote @file{ltx-sec.el}.
-
-@itemize @minus
-@item
-Sectioning level, toc, and title queries can be individually turned off.
-@item
-Label query can be turned on or off for selected sectioning levels.
-@item
-Label prefix can be different for different sectioning levels.
-@item 
-If the title (or toc) is empty, point will be positioned there.
-@item
-Users can add new hooks
-@end itemize
-
-@item
-@code{TeX-insert-macro} much smarter.
-
-It will now prompt for the symbol with completions, and for many symbols
-it will also prompt for each argument.  There are also completion on
-some of the arguments.
-
-@item
-Fixed center in figure environment. 
-
-Thanks to Thomas Koenig @samp{<ig25@@rz.uni-karlsruhe.de>}.
-
-@item
-Changed @code{\M-} to @code{\e} in all keybindings in order to better
-support 8-bit input on some GNU Emacs. Thanks to Peter Dalgaard
-@samp{<pd@@kubism.ku.dk>}.
-
-Please, implementors of 8-bit input extensions to GNU Emacs.
-@code{\M-x} does @emph{not} means @dfn{@kbd{x} with the 8-bit set}.  It
-means @dfn{pressing @kbd{x} while holding down the @key{meta} key}.
-Some systems (such as X11) are able to tell the different.  Thus, even
-if you implement 256 byte keymaps, @code{\M-x} should still expand
-@code{meta-prefix-char} followed by an @kbd{x} in the keymap.  This
-allows you to distinguish pressing @kbd{x} while holding down the
-@key{meta} key from entering a literal 8-bit character.
-
-@item
-Made the outline commands aware of the document style.
-
-That is, if the document style is @samp{article}, @samp{\section} will
-be one level below the @samp{\documentstyle}, while if the style is
-@samp{book}, @samp{\section} will be three levels below
-@samp{\documentstyle}.  This will make @code{show-children} work better
-at the top level.
-
-@item
-The makefiles are closer to GNU coding standard.
-
-They now understand `prefix' and some other macros.
-
-@item
-Added hooks to be run after list of environments or list of completion
-names are updated, and also added a hook to be called after each file
-has been loaded. Thanks to Piet van Oostrum @samp{<piet@@cs.ruu.nl>}.
-
-@item
-Added @samp{*} to lot of @code{(interactive)} declarations.
-
-@item
-The outline commands are now always accessible from @LaTeX{} mode.
-
-@item
-Generalized the keyboard remapping and double modes.
-
-These are found in the file @file{min-key.el}. 
-
-@item
-Smart Comments.
-
-Not really, but there are now two comment functions which use their
-arguments to determine what to do, instead of four functions ignoring
-their arguments.
-
-@item
-Add outline headers.
-
-It is now possible to add extra outline headers, by setting the variable
-@code{TeX-outline-extra}. 
-
-@item 
-Smart quotes even smarter.
-
-If you press @kbd{"} twice, it will insert an real double quote instead
-of two (or four) single quotes.  This is consistent with how remapping
-in @file{min-key.el} is done.
-
-@item
-Automatically untabify buffer when you save it.
-
-Hands up, everyone who have produced a `last revision' paper containing
-an unreadable list of data in the back, because @TeX{} does not
-understands tabs.
-
-@item
-Call show-all when you change major mode.
-
-Thanks to Inge Frick's @samp{<inge@@nada.kth.se>} @file{kill-fix.el}
-enhancement, outline minor mode can now guarantee that all text is shown
-when you leave the minor mode, even if you leave the minor mode by
-changing the major mode.
-
-@item
-Updated documentation for 7.0.
-
-Also added key, variable, function, and concept indexes, as well as this
-history section and a new chapter on multifile documents

-@end ifclear
-
-The modern and strongly recommended way of installing @AUCTeX{} is by
-using the Emacs package manager integrated in Emacs 24 and greater
-(@acronym{ELPA}).  Simply do @kbd{M-x list-packages @key{RET}}, mark the
-auctex package for installation with @kbd{i}, and hit @kbd{x} to execute
-the installation procedure.  That's all.
-
-@code{use-package} users can use this simple recipe in their
-@code{user-init-file} which essentially does the same as the manual
-installation explained above.
-
-@lisp
-(use-package tex
-  :ensure auctex)
-@end lisp
-
-Using the @acronym{ELPA} version has several advantages.  Besides being
-platform and @acronym{OS} independent, you will receive intermediate
-bugfix releases between major @AUCTeX{} releases conveniently.  For past
-@acronym{ELPA} releases, see
-@url{https://elpa.gnu.org/packages/auctex.html}.
-@ifclear rawfile
-Once the installation is completed, you can skip the rest of this
-section and proceed to @ref{Quick Start}.
-@end ifclear
-
-The remainder of this section is about installing @AUCTeX{} from a
-release tarball or from a checkout of the @AUCTeX{} repository.
-
-Installing @AUCTeX{} should be simple: merely @command{./configure},
-@command{make}, and @code{make install} for a standard site-wide
-installation (most other installations can be done by specifying a
-@option{--prefix=@dots{}} option).
-
-On many systems, this will already activate the package, making its
-modes the default instead of the built-in modes of Emacs.  If this is
-not the case, consult @ref{Loading the package}.  Please read through
-this document fully before installing anything.  The installation
-procedure has changed as compared to earlier versions.  Users of @w{MS

-@item GNU Emacs 25.1 or higher

-@item Windows
-Precompiled versions are available from

-@item macOS
-For an overview of precompiled versions of Emacs for macOS see for

-@item GNU/Linux
-Most GNU/Linux distributions nowadays provide a recent variant of Emacs

-@end table
-
-@item A working @TeX{} installation
-
-Well, @AUCTeX{} would be pointless without that.  Processing
-documentation requires @TeX{}, @LaTeX{} and Texinfo during installation.
-@previewlatex{} requires Dvips or @command{dvipng} for its operation in @acronym{DVI} mode.
-The default configuration of @AUCTeX{} is tailored for @w{@TeX{} Live}-based
-distributions, but can be adapted easily.
-
-@item A recent Ghostscript
-
-This is needed for operation of @previewlatex{} in both @acronym{DVI}
-and @acronym{PDF} mode.  Ghostscript version 7.07 or newer is required.
-
-@item GNU make
-
-Recent @AUCTeX{} uses GNU make specific capabilities in the Makefiles.
-If your @acronym{OS}'s default @command{make} command is not GNU make,
-you have to obtain it in order to build @AUCTeX{} by yourself.  GNU make
-is sometimes provided under the name @command{gmake} in your
-@acronym{OS}'s binary package system.
-
-@item The Texinfo package
-
-Strictly speaking, you can get away without it if you are building
-from the distribution tarball, have not modified any files and don't
-need a printed version of the manual: the pregenerated info file is

-@node Configure
-@section Configure
-
-The first step is to configure the source code, telling it where
-various files will be.  To do so, run
-
-@example
-./configure @var{options}
-@end example
-
-(Note: if you have fetched @AUCTeX{} from Git rather than
-a regular release, you will have to first follow the instructions in
-@file{README.GIT}).
-
-On many machines, you will not need to specify any options, but if
-@command{configure} cannot determine something on its own, you'll need to
-help it out with one of these options:
-
-@table @code
-@item --prefix=@var{prefix}
-All automatic placements for package components will be chosen from
-sensible existing hierarchies below this: directories like @file{man},
-@file{share} and @file{bin} are supposed to be directly below
-@var{prefix}.
-
-Only if no workable placement can be found there, in some cases an
-alternative search will be made in a prefix deduced from a suitable
-binary.
-
-@file{/usr/local} is the default @var{prefix}, intended to be suitable
-for a site-wide installation.  If you are packaging this as an
-operating system component for distribution, the setting @file{/usr}
-will probably be the right choice.  See @ref{Advice for package
-providers} for detail.
-
-If you are planning to install the package as a single non-priviledged
-user, you will typically set @var{prefix} to your home directory.
-Consult @ref{Advice for non-privileged users} for addtional
-instructions.
-
-@item --with-emacs=@var{/path/to/emacs}
-If you are using a pretest which isn't in your @env{PATH}, or
-@command{configure} is not finding the right Emacs executable, you can
-specify it with this option.
-
-@item --with-lispdir=@var{lispdir}
-This option specifies the location of the @file{site-lisp}
-directory within @code{load-path} under which the files will get
-installed (the bulk will get installed in a subdirectory).
-@command{./configure} should figure this out by itself.
-
-@item --with-auctexstartfile=@file{auctex.el}
-@itemx --with-previewstartfile=@file{preview-latex.el}
-This is the name of the respective startup files.  If @var{lispdir}
-contains a subdirectory @file{site-start.d}, the start files are
-placed there, and @file{site-start.el} should
-load them automatically.  Please be aware that you must not move the
-start files after installation since other files are found
-@emph{relative} to them.
-
-@item --with-packagelispdir=@file{auctex}
-This is the directory where the bulk of the package gets located.  The
-startfile adds this into @code{load-path}.
-
-@item --with-auto-dir=@var{/dir}
-You can use this option to specify the directory containing
-automatically generated information by @kbd{M-x TeX-auto-generate-global @key{RET}}.  It is not necessary for most
-@TeX{} installs, but may be used if you don't like the directory that
-configure is suggesting.
-
-@item --help
-This is not an option specific to @AUCTeX{}. A number of standard
-options to @command{configure} exist, and we do not have the room to
-describe them here; a short description of each is available, using
-@option{--help}.
-
-@c FIXME: It seems this no longer holds.
-@c If you use @samp{--help=recursive}, then also @previewlatex{}-specific
-@c options will get listed.
-
-@item --disable-preview
-This disables configuration and installation of @previewlatex{}.  This
-option is not actually recommended.  If your Emacs does not support
-images, you should really upgrade to a newer version.  Distributors
-should, if possible, refrain from distributing @AUCTeX{} and
-@previewlatex{} separately in order to avoid confusion and upgrade
-hassles if users install partial packages on their own.
-
-@item --with-texmf-dir=@var{/dir}
-@itemx --without-texmf-dir
-@cindex preview-install-styles
-This option is used for specifying a @acronym{TDS}-compliant directory
-hierarchy.  Using @code{--with-texmf-dir=@var{/dir}} you can specify
-where the @TeX{} @acronym{TDS} directory hierarchy resides, and the
-@TeX{} files will get installed in
-@file{@var{/dir}/tex/latex/preview/}.
-
-If you use the @option{--without-texmf-dir} option, the @TeX{}-related
-files will be kept in the Emacs Lisp tree, and at runtime the
-@env{TEXINPUTS} environment variable will be made to point there.  You
-can install those files into your own @TeX{} tree at some later time
-with @kbd{M-x preview-install-styles @key{RET}}.
-
-@item --with-tex-dir=@var{/dir}
-If you want to specify an exact directory for the preview @TeX{} files,
-use @code{--with-tex-dir=@var{/dir}}. In this case, the files will be
-placed in @file{@var{/dir}}, and you'll also need the following option:
-
-@item --with-doc-dir=@var{/dir}
-This option may be used to specify where the @TeX{} documentation goes.
-It is to be used when you are using @code{--with-tex-dir=@var{/dir}},
-but is normally not necessary otherwise.

-@end ifclear
-
-Once activated, the modes provided by @AUCTeX{} are used per default for
-all supported file types.  If you want to change the modes for which it
-is operative instead of the default, use
-@example
-@kbd{M-x customize-option @key{RET} TeX-modes @key{RET}}
-@end example
-
-If you want to remove a preinstalled @AUCTeX{} completely before any of
-its modes have been used,
-@lisp
-(unload-feature 'tex-site)
-@end lisp
-@noindent
-should accomplish that.
-
-@node Advice for package providers
-@section Providing @AUCTeX{} as a package
-
-As a package provider, you should make sure that your users will be
-served best according to their intentions, and keep in mind that a
-system might be used by more than one user, with different
-preferences.
-
-There are people that prefer the built-in Emacs modes for editing
-@TeX{} files, in particular plain @TeX{} users.  There are various
-ways to tell @AUCTeX{} even after auto-activation that it should
-not get used, and they are described in
-@ifset rawfile
-the @file{README} file.
-@end ifset
-@ifclear rawfile
-@ref{Introduction,,Introduction to @AUCTeX{}}.
-@end ifclear
-
-So if you have users that don't want to use the preinstalled @AUCTeX{},
-they can easily get rid of it.  Activating @AUCTeX{} by default is
-therefore a good choice.
-
-If the installation procedure did not achieve this already by placing
-@file{auctex.el} and @file{preview-latex.el} into a possibly existing
-@file{site-start.d} directory, you can do this by placing
-
-@lisp
-(load "auctex.el" nil t t)
-(load "preview-latex.el" nil t t)
-@end lisp
-
-@noindent in the system-wide @file{site-start.el}.
-
-The @option{--without-texmf-dir} option can be convenient for systems that
-are intended to support more than a single TeX distribution.  Since more
-often than not @TeX{} packages for operating system distributions are
-either much more outdated or much less complete than separately provided
-systems like @w{@TeX{} Live}, this method may be generally preferable
-when providing packages.
-
-The following package structure would be adequate for a typical fully
-supported Unix-like installation:
-
-@c FIXME: teTeX is much outdated now.
-@table @samp
-@item preview-tetex
-Style files and documentation for @file{preview.sty}, placed into a
-@TeX{} tree where it is accessible from the te@TeX{} executables usually
-delivered with a system.  If there are other commonly used @TeX{} system
-packages, it might be appropriate to provide separate packages for
-those.
-@item auctex-emacs-tetex
-This package will require the installation of @samp{preview-tetex} and
-will record in @code{TeX-macro-global} where to find the @TeX{} tree.
-It is also a good idea to run
-@example
-emacs -batch -f TeX-auto-generate-global
-@end example
-when either @AUCTeX{} or te@TeX{} get installed or upgraded.  If your
-users might want to work with a different @TeX{} distribution (nowadays
-pretty common), instead consider the following:
-@item auctex-emacs
-This package will be compiled with @option{--without-texmf-dir} and will
-consequently contain the @samp{preview} style files in its private
-directory.  It will probably not be possible to initialize
-@code{TeX-macro-global} to a sensible value, so running
-@code{TeX-auto-generate-global} does not appear useful.  This package
-would neither conflict with nor provide @samp{preview-tetex}.
-@end table
-
-@node Advice for non-privileged users
-@section Installation for non-privileged users
-
-Often people without system administration privileges want to install
-software for their private use.  In that case you need to pass more
-options to the @command{configure} script.
-
-The main expedient is using the @option{--prefix} option to the
-@command{configure} script, and let it point to the personal home
-directory.  In that way, resulting binaries will be installed under the
-@file{bin} subdirectory of your home directory, manual pages under
-@file{man} and so on.  It is reasonably easy to maintain a bunch of
-personal software, since the prefix argument is supported by most
-@command{configure} scripts.
-
-You often need to specify @option{--with-lispdir} option as well.
-If you haven't installed Emacs under your home directory and use Emacs
-installed in system directories, the @command{configure} script might not
-be able to figure out suitable place to install lisp files under your
-home directory.  In that case, the @command{configure} script would
-silently choose, by default, the @file{site-lisp} directory within
-@code{load-path} for the place, where administration privileges are
-usually required to put relevant files.  Thus you will have to tell
-the @command{configure} script explicitly where to put those files by,
-e.g., @code{--with-lispdir=@samp{/home/myself/share/emacs/site-lisp}}.
-
-You'll have to add something like
-@samp{/home/myself/share/emacs/site-lisp} to your @code{load-path}
-variable, if it isn't there already.
-
-In addition, you will have to tell @command{configure} script where to
-install @TeX{}-related files such as @file{preview.sty} if
-@previewlatex{} isn't disabled.  It is enough to specify
-@option{--with-texmf-dir=@file{$HOME/texmf}} for most typical cases, but
-you have to create the direcotry @file{$HOME/texmf} in advance if it
-doesn't exist.  If this prescription doesn't work, consider using one or
-more of the options @code{--with-texmf-dir=@var{/dir}},
-@code{--without-texmf-dir}, @code{--with-tex-dir=@var{/dir}} and
-@code{--with-doc-dir=@var{/dir}}.  See @ref{Configure} for detail of
-these options.
-
-Now here is another thing to ponder: perhaps you want to make it easy
-for other users to share parts of your personal Emacs configuration.  In
-general, you can do this by writing @samp{~myself/} anywhere where you
-specify paths to something installed in your personal subdirectories,
-not merely @samp{~/}, since the latter, when used by other users, will
-point to non-existent files.
-
-For yourself, it will do to manipulate environment variables in your
-@file{.profile} resp.@: @file{.login} files.  But if people will be
-copying just Elisp files, their copies will not work.  While it would
-in general be preferable if the added components where available from
-a shell level, too (like when you call the standalone info reader, or
-try using @file{preview.sty} for functionality besides of Emacs
-previews), it will be a big help already if things work from inside
-of Emacs.
-
-Here is how to do the various parts:
-
-@subheading Making the Elisp available
-
-In GNU Emacs, it should be sufficient if people just do
-
-@lisp
-(load "~myself/share/emacs/site-lisp/auctex.el" nil t t)
-(load "~myself/share/emacs/site-lisp/preview-latex.el" nil t t)
-@end lisp
-@noindent
-where the path points to your personal installation.  The rest of the
-package should be found relative from there without further ado.
-
-@subheading Making the Info files available
-
-For making the info files accessible from within Elisp, something like
-the following might be convenient to add into your or other people's
-startup files:
-
-@lisp
-(eval-after-load 'info
-   '(add-to-list 'Info-directory-list "~myself/info"))
-@end lisp
-
-@subheading Making the @LaTeX{} style available
-
-If you want others to be able to share your installation, you should
-configure it using @option{--without-texmf-dir}, in which case things
-should work as well for them as for you.
-
-@subsection Using @AUCTeX{} from local Git repo
-
-With the techniques described above, it is also possible to use @AUCTeX{}
-directly from a local Git repository.  Let's assume you have your Git
-repositories under @samp{~/development/}.
-
-First, you have to fetch a copy of the @AUCTeX{} Git repository.  In a
-shell, change directory to @samp{~/development/} and do:
-@example
-git clone https://git.savannah.gnu.org/git/auctex.git
-@end example
-
-Now change directory to @samp{~/development/auctex} and run
-@samp{./autogen.sh}.  Next thing is to run @command{configure} like this:
-@example
-./configure --without-texmf-dir --with-lispdir=.
-@end example
-
-@noindent
-When finished, simply enter
-@example
-make
-@end example
-@noindent
-and you're finished.  Note that the @samp{make install} step is not
-necessary.
-
-Now you have to tell Emacs about the plan.  The following variables must
-be set in your init file because their normal values are only correct when
-@AUCTeX{} is installed:
-@lisp
-(setq TeX-data-directory "~/development/auctex"
-      TeX-lisp-directory TeX-data-directory)
-@end lisp
-
-@noindent
-The info files will be available with this:
-@lisp
-(eval-after-load 'info
-   '(add-to-list 'Info-additional-directory-list
-                 "~/development/auctex/doc"))
-@end lisp
-
-@noindent
-Now you're ready to load @file{auctex.el} and @file{preview-latex.el} out
-of this directory:
-@lisp
-(load "~/development/auctex/auctex.el" nil t t)
-(load "~/development/auctex/preview-latex.el" nil t t)
-@end lisp

-@cindex Site customization
-@cindex Customization
-@cindex Customization, personal
-@cindex Customization, site
-Most of the site-specific customization should already have happened
-during configuration of @AUCTeX{}.  Any further customization can be
-done with customization buffers directly in Emacs.  Just type @kbd{M-x
-customize-group @key{RET} AUCTeX @key{RET}} to open the customization group for
-@AUCTeX{} or use the menu entries provided in the mode menus.  Editing
-the file @file{tex-site.el} as suggested in former versions of @AUCTeX{}
-should not be done anymore because the installation routine will
-overwrite those changes.
-
-You might check some options with a special significance.  They are
-accessible directly by typing @kbd{M-x customize-option @key{RET} <option>
-@key{RET}}.
-
-@defopt TeX-macro-global
-Directories containing the site's @TeX{} style files.
-@end defopt
-
-Normally, @AUCTeX{} will only allow you to complete macros and
-environments which are built-in, specified in @AUCTeX{} style files or
-defined by yourself.  If you issue the @kbd{M-x
-TeX-auto-generate-global} command after loading @AUCTeX{}, you will be
-able to complete on all macros available in the standard style files
-used by your document.  To do this, you must set this variable to a list
-of directories where the standard style files are located.  The
-directories will be searched recursively, so there is no reason to list
-subdirectories explicitly.  Automatic configuration will already have
-set the variable for you if it could use the program @command{kpsewhich}.
-In this case you normally don't have to alter anything.

-@end ifclear
-
-@ifset rawfile
-This file gives a brief overview of what @AUCTeX{} is.  It is
-@strong{not} an attempt to document @AUCTeX{}.  Real documentation for
-@AUCTeX{} is available in the manual, which should be available as an
-info file after installation.
-@end ifset
-
-@AUCTeX{} is a comprehensive customizable integrated environment for
-writing input files for @TeX{}, @LaTeX{}, @ConTeXt{}, Texinfo, and
-doc@TeX{} using Emacs.
-
-It supports you in the insertion of macros, environments, and sectioning
-commands by providing completion alternatives and prompting for
-parameters.  It automatically indents your text as you type it and lets
-you format a whole file at once.  The outlining and folding facilities
-provide you with a focused and clean view of your text.
-
-@AUCTeX{} lets you process your source files by running @TeX{} and
-related tools (such as output filters, post processors for generating
-indices and bibliographies, and viewers) from inside Emacs.  @AUCTeX{}
-lets you browse through the errors @TeX{} reported, while it moves the
-cursor directly to the reported error, and displays some documentation
-for that particular error.  This will even work when the document is
-spread over several files.
-
-One component of @AUCTeX{} that @LaTeX{} users will find attractive is
-@previewlatex{}, a combination of folding and in-source previewing
-that provides true ``What You See Is What You Get'' experience in your
-sourcebuffer, while letting you retain full control.
-@ifset rawfile
-For more information, see further below.
-@end ifset
-
-More detailed information about the features and usage of @AUCTeX{} can
-be found in the
-@ifset rawfile
-@AUCTeX{} manual.  You can access it from within Emacs by typing
-@kbd{C-h i d m auctex @key{RET}}.  If you prefer the standalone info
-reader, issue the command @code{info auctex} in a terminal.
-@end ifset
-@ifclear rawfile
-remainder of this manual.
-@end ifclear
-
-@AUCTeX{} is written entirely in Emacs Lisp, and hence you can easily
-add new features for your own needs.  It is a GNU project and
-distributed under the `GNU General Public License Version 3'.
-
-The most recent version is always available at
-@url{https://ftp.gnu.org/pub/gnu/auctex/}.
-
-WWW users may want to check out the @AUCTeX{} page at
-@url{https://www.gnu.org/software/auctex/}.
-
-For comprehensive information about how to install @AUCTeX{}
-@ifset rawfile
-read the file @file{INSTALL} or @file{INSTALL.windows}, respectively.
-@end ifset
-@ifclear rawfile
-@xref{Installation}, or @ref{Installation under MS Windows},
-respectively.

-@ifset rawfile
-the @file{CHANGES} file.
-@end ifset

-
-If you want to discuss @AUCTeX{} with other users or its developers,
-there are several mailing lists you can use.
-
-Send a mail with the subject ``subscribe'' to
-@email{auctex-request@@gnu.org} in order to join the general discussion
-list for @AUCTeX{}.  Articles should be sent to @email{auctex@@gnu.org}.
-In a similar way, you can subscribe to the @email{info-auctex@@gnu.org}
-list for just getting important announcements about @AUCTeX{}.  The list
-@email{bug-auctex@@gnu.org} is for bug reports which you should usually
-file with the @kbd{M-x TeX-submit-bug-report @key{RET}} command.  If you
-want to address the developers of @AUCTeX{} themselves with technical
-issues, they can be found on the discussion list
-@email{auctex-devel@@gnu.org}.

-@node Requirements, Installation Trouble, Introduction to FAQ, Frequently Asked Questions
-@section Requirements
-
-@subsection Which version of Emacs is needed?
-
-@previewlatex{} nominally requires @w{GNU Emacs} with a version of at
-least 25.1.
-
-@subsection Which versions of Ghostscript and @AUCTeX{} are needed?
-
-We recommend to use GNU or AFPL Ghostscript with a version of at least
-7.07.
-
-@previewlatex{} has been distributed as part of @AUCTeX{} since version
-11.80.  If your version of @AUCTeX{} is older than that, or if it does
-not contain a working copy of @previewlatex{}, complain to wherever you
-got it from.
-
-@subsection I have trouble with the display format...
-We recommend keeping the variable @code{preview-image-type} set to
-@code{dvipng} (if you have it installed) or @code{png}.  This is the
-default and can be set via the @samp{Preview/Customize} menu.
-
-All other formats are known to have inconveniences, either in file size
-or quality.  There are some Emacs versions around not supporting
-@acronym{PNG}; the proper way to deal with that is to complain to your
-Emacs provider.  Short of that, checking out @acronym{PNM} or
-@acronym{JPEG} formats might be a good way to find out whether the lack
-of @acronym{PNG} format support might be the only problem with your
-Emacs.
-
-@subsection For which OS does preview work?
-
-It is known to work under the X Window System for Linux and for several
-flavors of Unix: we have reports for HP and Solaris.
-
-There are several development versions of Emacs around for native MacOS
-Carbon, and @previewlatex{} is working with them, too.
-
-With Windows, both native Emacs and Cygwin Emacs should work.  However, it
-is known that @url{https://miktex.org/,MiK@TeX{}} sometimes doesn't work
-with @previewlatex{}.  In that case, use
-@url{https://tug.org/texlive/,@TeX{} Live} instead.
-
-@node Installation Trouble, Customization, Requirements, Frequently Asked Questions
-@section Installation Trouble
-
-@subsection I just get @samp{LaTeX found no preview images}.
-
-The reason for this is that @LaTeX{} found no preview images in the
-document in question.
-
-One reason might be that there are no previews to be seen.  If you have
-not used @previewlatex{} before, you might not know its manner of
-operation.  One sure-fire way to test if you just have a document where
-no previews are to be found is to use the provided example document
-@file{circ.tex} (you will have to copy it to some directory where you
-have write permissions).  If the symptom persists, you have a problem,
-and the problem is most likely a @LaTeX{} problem.  Here are possible
-reasons:
-
-@table @asis
-
-@item Filename database not updated
-Various @TeX{} distributions have their own ways of knowing where the
-files are without actually searching directories.  The normal
-@previewlatex{} installation should detect common tools for that purpose
-and use them.  If this goes wrong, or if the files get installed into a
-place where they are not looked for, the @LaTeX{} run will fail.
-
-@item An incomplete manual installation
-This should not happen if you followed installation instructions.
-Unfortunately, people know better all the time.  If only
-@file{preview.sty} gets installed without a set of supplementary files
-also in the @file{latex} subdirectory, @previewlatex{} runs will not
-generate any errors, but they will not produce any previews, either.
-
-@item An outdated @file{preview} installation
-The @file{preview.sty} package is useful for more than just
-@previewlatex{}.  For example, it is part of @w{@TeX{} Live}.  So you have
-to make sure that @previewlatex{} does not get to work with outdated
-style and configuration files: some newer features will not work with
-older @TeX{} style files, and really old files will make
-@previewlatex{} fail completely.  There usual is a local @file{texmf}
-tree, or even a user-specific tree that are searched before the default
-tree.  Make sure that the first version of those files that gets found
-is the correct one.

-@node Customization, Troubleshooting, Installation Trouble, Frequently Asked Questions
-@section Customization
-
-@subsection How to include additional environments like @code{enumerate}
-
-By default, @previewlatex{} is intended mainly for displaying
-mathematical formulas, so environments like @code{enumerate} or
-@code{tabular} (except where contained in a float) are not included.
-You can include them however manually by adding the lines:
-
-@example
-\usepackage[displaymath,textmath,sections,graphics,floats]@{preview@}
-\PreviewEnvironment@{enumerate@}
-@end example
-@noindent
-in your document header, that is before 
-
-@example
-\begin@{document@}
-@end example
-@noindent
-In general, @file{preview} should be loaded as the last thing before
-the start of document.
-
-Be aware that
-
-@example
-\PreviewEnvironment@{...@}
-@end example
-@noindent
-does not accept a comma separated
-list!  Also note that by putting more and more 
-
-@example
-\PreviewEnvironment@{...@}
-@end example
-@noindent
-in your document, it will look more and more like a @acronym{DVI} file
-preview when running @previewlatex{}.  Since each preview is treated as
-one large monolithic block by Emacs, one should really restrict
-previews to those elements where the improvement in visual
-representation more than makes up for the decreased editability.
-
-@subsection What if I don't want to change the document?
-The easiest way is to generate a configuration file in the current
-directory.  You can basically either create @file{prdefault.cfg} which
-is used for any use of the @samp{preview} package, or you can use
-@file{prauctex.cfg} which only applies to the use from with Emacs.  Let
-us assume you use the latter.  In that case you should write something like
-
-@example
-\InputIfFileExists@{preview/prauctex.cfg@}@{@}@{@}
-\PreviewEnvironment@{enumerate@}
-@end example
-@noindent
-in it.  The first line inputs the system-wide default configuration
-(the file name should match that, but not your own
-@file{prauctex.cfg}), then you add your own stuff.
-
-@subsection Suddenly I get gazillions of ridiculous pages?!?
-
-When @previewlatex{} works on extracting its stuff, it typesets each
-single preview on a page of its own.  This only happens when actual
-previews get generated.  Now if you want to configure @previewlatex{} in
-your document, you need to add your own @code{\usepackage} call to
-@samp{preview} so that it will be able to interpret its various
-definition commands.  It is an error to add the @code{active} option to
-this invocation: you don't want the package to be active unless
-@previewlatex{} itself enables the previewing operation (which it will).
-
-@subsection Does @previewlatex{} work with presentation classes?
-
-@previewlatex{} should work with most presentation classes.  However,
-since those classes often have macros or pseudo environments
-encompassing a complete slide, you will need to use the customization
-facilities of @file{preview.sty} to tell it how to resolve this, whether
-you want no previews, previews of whole slides or previews of inner
-material.
-
-@node Troubleshooting, Other formats, Customization, Frequently Asked Questions
-@section Troubleshooting
-
-@subsection Preview causes all sort of strange error messages
-
-When running @previewlatex{} and taking a look at either log file or
-terminal output, lots of messages like
-
-@example
-! Preview: Snippet 3 started.
-<-><->
-      
-l.52 \item Sie lassen sich als Funktion $
-                                         y = f(x)$ darstellen.
-! Preview: Snippet 3 ended.(491520+163840x2494310).
-<-><->
-      
-l.52 \item Sie lassen sich als Funktion $y = f(x)$
-                                                   darstellen.
-@end example
-@noindent
-appear (previous versions generated messages looking even more like
-errors).  Those are not real errors (as will be noted in the log
-file).  Or rather, while they @strong{are} really @TeX{} error
-messages, they are intentional.  This currently is the only reliable
-way to pass the information from the @LaTeX{} run of @previewlatex{} to
-its Emacs part about where the previews originated in the source text.
-Since they are actual errors, you will also get @AUCTeX{} to state
-@example
-Preview-LaTeX exited as expected with code 1 at Wed Sep  4 17:03:30
-@end example
-@noindent
-after the @LaTeX{} run in the run buffer.  This merely indicates that
-errors were present, and errors will always be present when
-@previewlatex{} is operating.  There might be also real errors, so in
-case of doubt, look for them explicitly in either run buffer or the
-resulting @file{.log} file.
-
-@subsection Why do my @acronym{DVI} and @acronym{PDF} output files vanish?
-
-In order to produce the preview images @previewlatex{} runs @LaTeX{} on
-the master or region file.  The resulting @acronym{DVI} or @acronym{PDF}
-file can happen to have the same name as the output file of a regular
-@LaTeX{} run.  So the regular output file gets overwritten and is
-subsequently deleted by @previewlatex{}.
-
-@subsection My output file suddenly only contains preview images?!
-
-As mentioned in the previews @acronym{FAQ} entry, @previewlatex{} might
-use the file name of the original output file for the creation of
-preview images.  If the original output file is being displayed with a
-viewer when this happens, you might see strange effects depending on the
-viewer, e.g.@: a message about the file being corrupted or the display of
-all the preview images instead of your typeset document.  (Also
-@pxref{Customization}.)
-
-
-@node Other formats, , Troubleshooting, Frequently Asked Questions
-@section @previewlatex{} when not using @LaTeX{}
-
-@subsection Does @previewlatex{} work with  PDF@LaTeX{}?
-
-Yes, as long as you use @AUCTeX{}'s own PDF@LaTeX{} mode and have not
-messed with @samp{TeX-command-list}.
-
-@subsection Does @previewlatex{} work with @samp{elatex}?
-
-No problem here.  If you configure your @AUCTeX{} to use @samp{elatex},
-or simply have @samp{latex} point to @samp{elatex}, this will work fine.
-Modern @TeX{} distributions use e@TeX{} for @LaTeX{}, anyway.
-
-@subsection Does @previewlatex{} work with @ConTeXt{}?
-
-In short, no.  The @samp{preview} package is
-@LaTeX{}-dependent.  Adding support for other formats requires
-volunteers.
-
-@subsection Does @previewlatex{} work with plain @TeX{}?
-
-Again, no.  Restructuring the @samp{preview} package for @samp{plain}
-operation would be required.  Volunteers welcome.
-
-In some cases you might get around by making a wrapper pseudo-Master
-file looking like the following:
-
-@example
-\documentclass@{article@}
-\usepackage@{plain@}
-\begin@{document@}
-\begin@{plain@}
-\input myplainfile
-\end@{plain@}

-@previewlatex{} is a package embedding preview fragments into Emacs
-source buffers under the @AUCTeX{} editing environment for @LaTeX{}.  It
-uses @file{preview.sty} for the extraction of certain environments (most
-notably displayed formulas).  Other applications of this style file are
-possible and exist.
-
-The name of the package is really @samp{preview-latex}, all in

-sans-serif font to visually offset it.

-@itemx Preview/Generate previews (or toggle) at point
-If the cursor is positioned on or inside of a preview area, this
-toggles its visibility, regenerating the preview if necessary.  If not,
-it will run the surroundings through preview.  The surroundings include
-all areas up to the next valid preview, unless invalid previews occur
-before, in which case the area will include the last such preview in
-either direction.  And overriding any other
-action, if a region is active (@code{transient-mark-mode}), it is run
-through @code{preview-region}.
-@kindex @kbd{C-c C-p C-p}
-@findex preview-at-point
-
-@item @kbd{@key{mouse-2}}
-The middle mouse button has a similar action bound to it as
-@code{preview-at-point}, only that it knows which preview to apply it to
-according to the position of the click.  You can click either anywhere
-on a previewed image, or when the preview is opened and showing the
-source text, you can click on the icon preceding the source text.  In
-other areas, the usual mouse key action (typically: paste) is not
-affected.
-
-@item @kbd{@key{mouse-3}}
-The right mouse key pops up a context menu with several options:
-toggling the preview, regenerating it, removing it (leaving the
-unpreviewed text), copying the text inside of the preview, and copying
-it in a form suitable for copying as an image into a mail or news
-article.  This is a one-image variant of the following command:
-
-@item @kbd{C-c C-p C-w}
-@itemx @code{preview-copy-region-as-mml}
-@itemx Copy a region as MML
-@kindex @kbd{C-c C-p C-w}
-@findex preview-copy-region-as-mml
-This command is also available as a variant in the context menu on the
-right mouse button (where the region is the preview that has been
-clicked on).  It copies the current region into the kill buffer in a
-form suitable for copying as a text including images into a mail or news
-article using mml-mode (@pxref{Composing,,Composing,emacs-mime,Emacs
-MIME}).
-
-If you regenerate or otherwise kill the preview in its source buffer
-before the mail or news gets posted, this will fail.  Also you should
-generate images you want to send with @code{preview-transparent-border}
-@vindex preview-transparent-border
-set to @code{nil}, or the images will have an ugly border.
-@previewlatex{} detects this condition and asks whether to regenerate
-the region with borders switched off.  As this is an asynchronous
-operation running in the background, you'll need to call this command
-explicitly again to get the newly generated images into the kill ring.
-
-Preview your articles with @code{mml-preview} (on @kbd{C-c C-m P})

-preamble, do this again.  @previewlatex{} will try to detect the

-effectively changes because some included file or style file is
-tampered with.

-Customization options can be found by typing @kbd{M-x customize-group
-@key{RET} preview @key{RET}}.  Remember to set the option when you have
-changed it.  The list of suggestions can be made very long (and is
-covered in detail in @ref{For advanced users}), but some are:
-
-@itemize @bullet
-@item Change the color of the preview background
-
-If you use a non-white background in Emacs, you might have color
-artifacts at the edges of your previews.  Playing around with the option
-@code{preview-transparent-color} in the @samp{Preview Appearance} group
-might improve things.  With some settings, the cursor may cover the
-whole background of a preview, however.
-
-This option is specific to the display engine in use.
-
-@item Showing @code{\label}s
-@cindex Showing @code{\label}s
-
-When using @previewlatex{}, the @code{\label}s are hidden by the
-previews.  It is possible to make them visible in the output
-by using the @LaTeX{} package @code{showkeys} alternatively
-@code{showlabels}.  However, the boxes of these labels will be outside
-the region @previewlatex{} considers as the preview image.  To enable a
-similar mechanism internal to @previewlatex{}, enable the
-@code{showlabels} option in the variable
-@code{preview-default-option-list} in the @samp{Preview Latex} group.
-@vindex preview-default-option-list
-
-It must be noted, however, that a much better idea may be to use the
-Ref@TeX{} package for managing references.  @xref{RefTeX in a
-Nutshell,,RefTeX in a Nutshell,reftex,The Ref@TeX{} Manual}.
-
-@item Open previews automatically
-
-The current default is to open previews automatically when you enter
-them with cursor left/right motions.  Auto-opened previews will close
-again once the cursor leaves them again (this is also done when doing
-incremental search, or query-replace operations), unless you changed
-anything in it.  In that case, you will have to regenerate the preview
-(via e.g., @kbd{C-c C-p C-p}).  Other options for
-@code{preview-auto-reveal} are available via @code{customize}.
-
-@item Automatically cache preambles
-
-Currently @previewlatex{} asks you whether you want to cache the
-document preamble (everything before @code{\begin@{document@}}) before
-it generates previews for a buffer the first time.  Caching the preamble
-will significantly speed up regeneration of previews.  The larger your
-preamble is, the more this will be apparent.  Once a preamble is cached,
-@previewlatex{} will try to keep track of when it is changed, and dump
-a fresh format in that case.  If you experience problems with this, or
-if you want it to happen without asking you the first time, you can
-customize the variable @code{preview-auto-cache-preamble}.
-@vindex preview-auto-cache-preamble
-@cindex Caching a preamble
-
-@item Attempt to keep counters accurate when editing
-
-@vindex preview-preserve-counters
-@vindex preview-required-option-list
-Since @previewlatex{} frequently runs only small regions through
-@LaTeX{}, values like equation counters are not consistent from run to
-run.  If this bothers you, customize the variable
-@code{preview-preserve-counters} to @code{t} (this is consulted by
-@code{preview-required-option-list}).  @LaTeX{} will then output a load
-of counter information during compilation, and this information will be
-used on subsequent updates to keep counters set to useful values.  The
-additional information takes additional time to analyze, but this is
-relevant mostly only when you are regenerating all previews at once, and
-maybe you will be less tempted to do so when counters appear more or
-less correct.
-
-@item Preview your favourite @LaTeX{} constructs
-
-@vindex preview-default-option-list
-@vindex preview-default-preamble
-If you have a certain macro or environment that you want to preview,
-first check if it can be chosen by cutomizing
-@code{preview-default-option-list} in the @samp{Preview Latex} group.
-
-If it is not available there, you can add it to
-@code{preview-default-preamble} also in the @samp{Preview Latex} group,
-by adding a @code{\PreviewMacro} or @code{\PreviewEnvironment} entry
-(@pxref{Provided commands}) @emph{after} the @code{\RequirePackage}
-line.  For example, if you want to preview the @code{center}
-environment, press the @key{Show} button and the last @key{INS} button,
-then add
-
-@example
-\PreviewEnvironment@{center@}
-@end example
-@noindent
-in the space that just opened.  Note that since @code{center} is a
-generic formatting construct of @LaTeX{}, a general configuration like
-that is not quite prudent.  You better to do this on a per-document
-base so that it is easy to disable this behavior when you find this
-particular entry gives you trouble.
-
-One possibility is to save such settings in the corresponding file-local
-variable instead of your global configuration (@pxref{File
-Variables,,Local Variables in Files,emacs,GNU Emacs Manual}).  A perhaps
-more convenient place for such options would be in a configuration file
-in the same directory with your project (@pxref{Package options}).
-
-The usual file for @previewlatex{} preconfiguration is
-@file{prauctex.cfg}.  If you also want to keep the systemwide defaults,
-you should add a line
-
-@example
-\InputIfFileExists@{preview/prauctex.cfg@}@{@}@{@}
-@end example
-@noindent
-to your own version of @file{prauctex.cfg} (this is assuming that
-global files relating to the @code{preview} package are installed in a
-subdirectory @file{preview}, the default behavior).
-
-@item Don't preview inline math
-@cindex Inline math
-@vindex preview-default-option-list
-
-If you have performance problems because your document is full of inline
-math (@code{$@dots{}$}), or if your usage of @code{$} conflicts with
-@previewlatex{}'s, you can turn off inline math previews.  In the
-@samp{Preview Latex} group, remove @code{textmath} from
-@code{preview-default-option-list} by customizing this variable.

-in order to customize these variables, or use the menus for it.  We
-explain the various available options together with explaining how they
-work together in making @previewlatex{} work as intended.
-
-@vtable @code
-@item preview-LaTeX-command
-When you generate previews on a buffer or a region, the command in
-@code{preview-LaTeX-command} gets run (that variable should only be
-changed with Customize since its structure is somewhat peculiar, though
-expressive).  As usual with @AUCTeX{}, you can continue working while
-this is going on.  It is not a good idea to change the file until after
-@previewlatex{} has established where to place the previews which it can
-only do after the @LaTeX{} run completes.  This run produces a host of
-pseudo-error messages that get parsed by @previewlatex{} at the end of
-the @LaTeX{} run and give it the necessary information about where in
-the source file the @LaTeX{} code for the various previews is located
-exactly.  The parsing takes a moment and will render Emacs busy.
-
-@item preview-LaTeX-command-replacements
-This variable specifies transformations to be used before calling the
-configured command.  One possibility is to have @samp{\pdfoutput=0 }
-appended to every command starting with @samp{pdf}.  This particular
-setting is available as the shortcut
-@code{preview-LaTeX-disable-pdfoutput}.  Since @previewlatex{} can work
-with @acronym{PDF} files by now, there is little incentive for using
-this option, anymore (for projects not requiring @acronym{PDF} output,
-the added speed of @command{dvipng} might make this somewhat attractive).
-
-@item preview-required-option-list
-@code{preview-LaTeX-command} uses @code{preview-required-option-list} in
-order to pass options such as @option{auctex}, @option{active} and
-@option{dvips} to the @file{preview} package.  This means that the user
-need (and should) not supply these in the document itself in case he
-wants to be able to still compile his document without it turning into
-an incoherent mass of little pictures.  These options even get passed
-in when the user loads @file{preview} explicitly in his document.
-
-The default includes an option @code{counters} that is controlled by the
-boolean variable
-
-@item preview-preserve-counters
-This option will cause the @file{preview} package to emit information
-that will assist in keeping things like equation counters and section
-numbers reasonably correct even when you are regenerating only single
-previews.
-
-@item preview-default-option-list
-@itemx preview-default-preamble
-If the document does not call in the package @code{preview} itself (via
-@code{\usepackage}) in the preamble, the preview package is loaded using
-default options from @code{preview-default-option-list} and additional
-commands specified in @code{preview-default-preamble}.
-
-@item preview-fast-conversion
-This is relevant only for @acronym{DVI} mode.  It defaults to `On' and
-results in the whole document being processed as one large PostScript
-file from which the single images are extracted with the help of parsing
-the PostScript for use of so-called @acronym{DSC} comments.  The
-bounding boxes are extracted with the help of @TeX{} instead of getting
-them from Dvips.  If you are experiencing bounding box problems, try
-setting this option to `Off'.
-
-@item preview-prefer-TeX-bb
-If this option is `On', it tells @previewlatex{} never to try to extract
-bounding boxes from the bounding box comments of @acronym{EPS} files,
-but rather rely on the boxes it gets from @TeX{}.  If you activated
-@code{preview-fast-conversion}, this is done, anyhow, since there are no
-@acronym{EPS} files from which to read this information.  The option
-defaults to `Off', simply because about the only conceivable reason to
-switch off @code{preview-fast-conversion} would be that you have some
-bounding box problem and want to get Dvips' angle on that matter.
-
-@item preview-scale-function
-@itemx preview-reference-face
-@itemx preview-document-pt-list
-@itemx preview-default-document-pt
-@code{preview-scale-function} determines by what factor
-images should be scaled when appearing on the screen.  If you specify a
-numerical value here, the physical size on the screen will be that of
-the original paper output scaled by the specified factor, at least if
-Emacs' information about screen size and resolution are correct.  The
-default is to let @code{preview-scale-from-face} determine the scale
-function.  This function determines the scale factor by making the
-size of the default font in the document match that of the on-screen
-fonts.
-
-The size of the screen fonts is deduced from the font
-@code{preview-reference-face} (usually the default face used for
-display), the size of the default font for the document is determined
-by calling @code{preview-document-pt}.
-@findex preview-document-pt
-This function consults the members of @code{preview-document-pt-list} in
-turn until it gets the desired information.  The default consults first
-@code{preview-parsed-font-size},
-@vindex preview-parsed-font-size
-then calls @code{preview-auctex-font-size}
-@findex preview-auctex-font-size
-which asks @AUCTeX{} about any size specification like @option{12pt} to
-the documentclass that it might have detected when parsing the document, and
-finally reverts to just assuming @code{preview-default-document-pt} as
-the size used in the document (defaulting to 10pt).
-
-If you find that the size of previews and the other Emacs display
-clashes, something goes wrong.  @code{preview-parsed-font-size} is
-determined at @code{\begin@{document@}} time; if the default font size
-changes after that, it will not get reported.  If you have an outdated
-version of @file{preview.sty} in your path, the size might not be
-reported at all.  If in this case @AUCTeX{} is unable to find a size
-specification, and if you are using a document class with a different
-default value (like @samp{KomaScript}), the default fallback assumption will
-probably be wrong and @previewlatex{} will scale up things too large.
-So better specify those size options even when you know that @LaTeX{}
-does not need them: @previewlatex{} might benefit from them.  Another
-possibility for error is that you have not enabled @AUCTeX{}'s document
-parsing options.  The fallback method of asking @AUCTeX{} about the size
-might be disabled in future versions of @previewlatex{} since in
-general it is more reliable to get this information from the @LaTeX{}
-run itself.
-
-@item preview-fast-dvips-command
-@itemx preview-dvips-command
-The regular command for turning a @acronym{DVI} file into a single
-PostScript file is @code{preview-fast-dvips-command}, while
-@code{preview-dvips-command} is used for cranking out a @acronym{DVI}
-file where every preview is in a separate @acronym{EPS} file.  Which of
-the two commands gets used depends on the setting of
-@code{preview-fast-conversion}.  The printer specified here
-is @option{-Pwww} by default, which will usually get you scalable fonts
-where available.  If you are experiencing problems, you might want to try
-playing around with Dvips options (@xref{Command-line options,,,dvips}).
-
-The conversion of the previews into PostScript or @acronym{EPS} files
-gets started after the @LaTeX{} run completes when Emacs recognizes the
-first image while parsing the error messages.  When Emacs has finished
-parsing the error messages, it activates all detected previews.  This
-entails throwing away any previous previews covering the same areas, and
-then replacing the text in its visual appearance by a placeholder
-looking like a roadworks sign.
-
-@item preview-nonready-icon-specs
-This is the roadworks sign displayed while previews are being prepared.
-You may want to customize the font sizes at which @previewlatex{}
-switches over between different icon sizes, and the ascent ratio which
-determines how high above the base line the icon gets placed.
-
-@item preview-error-icon-specs
-@itemx preview-icon-specs
-Those are icons placed before the source code of an opened preview and,
-respectively, the image specs to be used for PostScript errors, and a
-normal open preview in text representation.
-
-@item preview-inner-environments
-This is a list of environments that are regarded as inner levels of an
-outer environment when doing @code{preview-environment}.  One example
-when this is needed is in
-@code{\begin@{equation@}\begin@{split@}@dots{}\end@{split@}\end@{equation@}}, and
-accordingly @code{split} is one entry in
-@code{preview-inner-environments}.
-
-@end vtable

-@section The preview images
-
-@vtable @code
-@item preview-image-type
-@itemx preview-image-creators
-@itemx preview-gs-image-type-alist
-What happens when @LaTeX{} is finished depends on the configuration of
-@code{preview-image-type}.  What to do for each of the various settings
-is specified in the variable @code{preview-image-creators}.  The options
-to pass into Ghostscript and what Emacs image type to use is specified
-in @code{preview-gs-image-type-alist}.
-
-@code{preview-image-type} defaults to @code{png}.  For this to work,
-your version of Ghostscript needs to support the @option{png16m} device.
-If you are experiencing problems here, you might want to reconfigure
-@code{preview-gs-image-type-alist} or @code{preview-image-type}.  Reconfiguring
-@code{preview-image-creators} is only necessary for adding additional
-image types.
-
-Most devices make @previewlatex{} start up a single Ghostscript process
-for the entire preview run (as opposed to one per image) and feed it
-either sections of a @acronym{PDF} file (if PDF@LaTeX{} was used), or
-(after running Dvips) sections of a single PostScript file or separate
-@acronym{EPS} files in sequence for conversion into @acronym{PNG} format
-which can be displayed much faster by Emacs.  Actually, not in sequence
-but backwards since you are most likely editing at the end of the
-document.  And as an added convenience, any preview that happens to be
-on-screen is given higher priority so that @previewlatex{} will first
-cater for the images that are displayed.  There are various options
-customizable concerning aspects of that operation, see the customization
-group @samp{Preview Gs} for this.
-
-Another noteworthy setting of @code{preview-image-type} is
-@samp{dvipng}: in this case, the @command{dvipng}
-@pindex dvipng 
-program will get run on @acronym{DVI} output (see below for @acronym{PDF}).
-This is in general much faster than Dvips and Ghostscript.  In that
-case, the option
-
-@item preview-dvipng-command
-will get run for doing the conversion, and it is expected that
-
-@item preview-dvipng-image-type
-images get produced (@samp{dvipng} might be configured for other image
-types as well).  You will notice that @code{preview-gs-image-type-alist}
-contains an entry for @code{dvipng}: this actually has nothing to with
-@samp{dvipng} itself but specifies the image type and Ghostscript device
-option to use when @samp{dvipng} can't be used.  This will obviously be
-the case for @acronym{PDF} output by PDF@LaTeX{}, but it will also happen
-if the @acronym{DVI} file contains PostScript specials in which case the
-affected images will get run through Dvips and Ghostscript once
-@samp{dvipng} finishes.
-
-Note for p@LaTeX{} and up@LaTeX{} users: It is known that @command{dvipng}
-is not compatible with p@LaTeX{} and up@LaTeX{}.  If
-@code{preview-image-type} is set to @samp{dvipng} and (u)p@LaTeX{} is
-used, @samp{dvipng} just fails and @previewlatex{} falls back on Dvips
-and Ghostscript.
-
-@item preview-gs-options
-Most interesting to the user perhaps is the setting of this variable.
-It contains the default antialiasing settings @option{-dTextAlphaBits=4}
-and @option{-dGraphicsAlphaBits=4}.  Decreasing those values to 2 @w{or
-1} might increase Ghostscript's performance if you find it lacking.
-@end vtable
-
-Running and feeding Ghostscript from @previewlatex{} happens
-asynchronously again: you can resume editing while the images arrive.
-While those pretty pictures filling in the blanks on screen tend to
-make one marvel instead of work, rendering the non-displayed images
-afterwards will not take away your attention and will eventually
-guarantee that jumping around in the document will encounter only
-prerendered images.
-
-@node Misplaced previews,  , The preview images, For advanced users
-@section Misplaced previews
-
-If you are reading this section, the first thing is to check that your
-problem is not caused by x-symbol in connection with an installation not
-supporting 8-bit characters (@pxref{x-symbol interoperation}).  If not,
-here's the beef:
-
-As explained previously, Emacs uses pseudo-error messages generated by
-the @samp{preview} package in order to pinpoint the exact source
-location where a preview originated.  This works in running text, but
-fails when preview material happens to lie in macro arguments, like the
-contents of @code{\emph}.  Those macros first read in their entire
-argument, munge it through, perhaps transform it somehow, process it and
-perhaps then typeset something.  When they finally typeset something,
-where is the location where the stuff originated? @TeX{}, having read in
-the entire argument before, does not know and actually there would be no
-sane way of defining it.
-
-For previews contained inside such a macro argument, the default
-behaviour of @previewlatex{} is to use a position immediately after the
-closing brace of the argument.  All the previews get placed there, all at
-a zero-width position, which means that Emacs displays it in an order
-that @previewlatex{} cannot influence (currently in Emacs it is even
-possible that the order changes between runs).  And since the placement
-of those previews is goofed up, you will not be able to regenerate them
-by clicking on them.  The default behaviour is thus somewhat undesirable.
-
-The solution (like with other preview problems) is to tell the @LaTeX{}
-@samp{preview} package how to tackle this problem (@pxref{The LaTeX
-style file}).  Simply, you don't need @code{\emph} do anything at all
-during previews! You only want the text math previewed, so the solution
-is to use @code{\PreviewMacro*\emph} in the preamble of your document
-which will make @LaTeX{} ignore @code{\emph} completely as long as it is
-not part of a larger preview (in which case it gets typeset as
-usual).  Its argument thus becomes ordinary text and gets treated like
-ordinary text.
-
-Note that it would be a bad idea to declare
-@code{\PreviewMacro*[@{@{@}@}]\emph} since then both @code{\emph} as
-well as its argument would be ignored instead of previewed.  For
-user-level macros, this is almost never wanted, but there may be
-internal macros where you might want to ignore internal arguments.
-
-The same mechanism can be used for a number of other text-formatting
-commands like @code{\textrm}, @code{\textit} and the like.  While they
-all use the same internal macro @code{\text@@command}, it will not do to
-redefine just that, since they call it only after having read their
-argument in, and then it already is too late.  So you need to disable
-every of those commands by hand in your document preamble.
-
-Actually, we wrote all of the above just to scare you.  At least all of
-the above mentioned macros and a few more are already catered for by a
-configuration file @file{prauctex.cfg} that gets loaded by default
-unless the @samp{preview} package gets loaded with the @option{noconfig}
-option.  You can make your own copy of this file in a local directory
-and edit it in case of need.  You can also add loading of a file of your
-liking to @code{preview-default-preamble},
-@vindex preview-default-preamble
-or alternatively do the
-manual disabling of your favorite macro in
-@code{preview-default-preamble},
-@vindex preview-default-preamble
-which is customizable in the @samp{Preview Latex} group.

-@end ifclear
-
-Some fonts have been reported to produce wrong characters with
-@previewlatex{}.  @previewlatex{} calls Dvips by default with the option
-@option{-Pwww} in order to get scalable fonts for nice results.  If you
-are using antialiasing, however, the results might be sufficiently nice
-with bitmapped fonts, anyway.  You might try @option{-Ppdf} for another
-stab at scalable fonts, or other printer definitions.  Use
-
-@display
-@kbd{M-x customize-option @key{RET} preview-fast-dvips-command @key{RET}}
-@end display
-@noindent
-and
-@display
-@kbd{M-x customize-option @key{RET} preview-dvips-command @key{RET}}
-@end display
-@noindent
-in order to customize this.
-
-One particular problem is that several printer setup files (typically in
-a file called @file{/usr/share/texmf/dvips/config/config.pdf} if you are
-using the @option{-Ppdf} switch) contain the @option{G} option for
-`character shifting'.  This option will result in @samp{fi} being
-rendered as @samp{@pounds{}} (British Pounds sign) in several fonts,
-unless your version of Dvips has a long-standing bug in its
-implementation fixed (only very recent versions of Dvips have).
-
-@node Too small bounding boxes
-@section Too small bounding boxes
-The bounding box of a preview is determined by the @LaTeX{} package
-using the pure @TeX{} bounding boxes.  If there is material extending
-outside of the @TeX{} box, that material will be missing from the
-preview image.  This happens for the label-showing boxes from
-the @code{showkeys} package.  This particular problem can be
-circumvented by using the @code{showlabels} option of the preview
-package.
-
-In general, you should try to fix the problem in the @TeX{} code, like
-avoiding drawing outside of the picture with PSTricks.
-
-One possible remedy is to set
-@code{preview-fast-conversion} to `Off' 
-@ifset rawfile
-(see the manual).
-@end ifset
-@ifclear rawfile
-(@pxref{The Emacs interface}).
-@end ifclear
-The conversion will take more time, but will then use the bounding boxes
-from @acronym{EPS} files generated by Dvips.
-
-Dvips generally does not miss things, but it does not understand
-PostScript constructs like @code{\resizebox} or @code{\rotate} commands,
-so will generate rather wrong boxes for those.  Dvips can be helped with
-the @code{psfixbb} package option to preview 
-@ifset rawfile
-(see the manual),
-@end ifset
-@ifclear rawfile
-(@pxref{The LaTeX style file}),
-@end ifclear
-which will tag the corners of the included @TeX{} box.  This will mostly
-be convenient for @emph{pure} PostScript stuff like that created by
-PSTricks, which Dvips would otherwise reserve no space for.
-
-@c FIXME: It seems that x-symbol is much outdated.
-@node x-symbol interoperation
-@section x-symbol interoperation
-
-Thanks to the work of Christoph Wedler, starting with version
-@samp{4.0h/beta} of x-symbol, the line parsing of @AUCTeX{} and
-@previewlatex{} is fully supported.  Earlier versions exhibit problems.
-However, versions before @samp{4.2.2} will cause a drastic slowdown of
-@previewlatex{}'s parsing pass, so we don't recommend to use versions
-earlier than that.
-
-If you wonder what x-symbol is, it is a package that transforms various
-tokens and subscripts to a more readable form while editing and offers a
-few input methods handy especially for dealing with math. Take a look at
-@uref{http://x-symbol.sourceforge.net/}.
-
-x-symbol versions up to @samp{4.5.1-beta} at least require an 8bit-clean @TeX{}
-implementation (meaning that its terminal output should not use
-@samp{^^}-started escape sequences) for cooperation with
-@previewlatex{}.  Later versions may get along without it, like
-@previewlatex{} does now.
-
-If you experience problems with @file{circ.tex} in connection with both
-x-symbol and Latin-1 characters, you may need to change your language
-environment or, as a last resort, customize the variable
-@code{LaTeX-command-style} by replacing the command @code{latex} with
-@code{latex -translate-file=cp8bit}.
-
-@node Middle-clicks paste instead of toggling
-@section Middle-clicks paste instead of toggling
-
-This is probably the fault of your favorite package.  @file{isearch.el}
-is known to be affected while searches are in progress, but the code is
-such a complicated mess that no patch is in sight.  Better just end the
-search with @kbd{@key{RET}} before toggling and resume with @kbd{C-s
-C-s} or similar afterwards.  Since previews over the current match will
-auto-open, anyway, this should not be much of a problem in practice.
-
-@node No images are displayed with gs 9.27 and earlier
-@section No images are displayed with gs 9.27 and earlier
-
-@previewlatex{} tries to adjust the foreground and background colors of
-generated images to those of Emacs.  Unfortunately, incompatible changes
-introduced in Ghostscript 9.27 breaks the traditional method partially,
-and @previewlatex{} can display no images under certain circumstances.
-
-A new method implemented alternatively works only with Ghostscript >
-9.27.  If you are using Ghostscript 9.27 or earlier, customize the
-option @code{preview-pdf-adjust-color-method}.
-
-@defopt preview-pdf-adjust-color-method
-Method to adjust colors of images generated from @acronym{PDF}.  It is
-not consulted when the @LaTeX{} command produces @acronym{DVI} files.
-
-When the option is @code{t} (default), @previewlatex{} adjusts the FG
-and BG colors of the generated images by the new method.  This method
-requires that Ghostscript has working @code{DELAYBIND} feature, thus is
-invalid with gs 9.27 (and possibly < 9.27).
-
-When it is @code{compatible}, @previewlatex{} uses traditional method.
-This option is provided for backward compatibility with older gs.  See
-the below explanation for detail.
-
-When @code{nil}, no adjustment is done and ``black on white'' image is
-generated regardless of Emacs color.  This is provided for fallback for
-gs 9.27 users with customized foreground color.  See the below
-explanation for detail.
-
-When the @LaTeX{} command produces @acronym{PDF} rather than
-@acronym{DVI} and Emacs has non-trivial foreground color, the
-traditional method (@code{compatible}) makes gs >= 9.27 to stop with
-error.  Here, ``non-trivial foreground color'' includes customized
-themes.
-
-If you use such non-trivial foreground color and the version of
-Ghostscript equals to 9.27, you have two options:
-@enumerate
-@item
-Choose the value @code{compatible} and customize
-@code{preview-reference-face} to have default (black) foreground color.
-This makes the generated image almost non-readable on dark background,
-so the next option would be your only choice in that case.
-@item
-Choose the value @code{nil}, which forces plain ``black on white''
-appearance for the generated image.  You can at least read what are
-written in the image although they may not match with your Emacs color
-well.
-@end enumerate
-
-The default value used to be @code{compatible} for short period before
-Ghostscript 9.50 was released but now is @code{t}.

-@cindex Philosophy of @previewlatex{}
-@acronym{WYSIWYG} (what you see is what you get) sometimes is considered
-all the rage, sometimes frowned upon.  Do we really want it?  Wrong
-question.  The right question is @emph{what} we want from it.  Except
-when finetuning the layout, we don't want to use printer fonts for
-on-screen text editing.  The low resolution and contrast of a computer
-screen render all but the coarsest printer fonts (those for low-quality
-newsprint) unappealing, and the margins and pagination of the print are
-not wanted on the screen, either.  On the other hand, more complex
-visual compositions like math formulas and tables can't easily be taken
-in when seen only in the source.  @previewlatex{} strikes a balance: it
-only uses graphic renditions of the output for certain, configurable
-constructs, does this only when told, and then right in the source code.
-Switching back and forth between the source and preview is easy and
-natural and can be done for each image independently.  Behind the scenes
-of @previewlatex{}, a sophisticated framework of other programs like
-@samp{dvipng}, Dvips and Ghostscript are employed together with a
-special @LaTeX{} style file for extracting the material of interest in
-the background and providing fast interactive response.

-@node  Activating preview-latex, Getting started, What use is it?, Introduction
-@section Activating @previewlatex{}
-@cindex Activation
-After installation, the package may need to be activated (and remember
-to activate @AUCTeX{} too).  If @previewlatex{} is installed via the
-Emacs package manager (@acronym{ELPA}), activation should be automatic
-upon installation.
-
-The usual activation (if it is not done automatically) would be
-
-@example
-(load "preview-latex.el" nil t t)
-@end example
-
-If you still don't get a ``Preview'' menu in @LaTeX{} mode in spite
-of @AUCTeX{} showing its ``Command'', your installation is broken.  One
-possible cause are duplicate Lisp files that might be detectable with
-@kbd{M-x list-load-path-shadows @key{RET}}.
-
-@node Getting started, Basic modes of operation, Activating preview-latex, Introduction
-@section Getting started
-
-Once activated, @previewlatex{} and its documentation will be accessible
-via its menus (note that @previewlatex{} requires @AUCTeX{} to be
-loaded).  When you have loaded a @LaTeX{} document (a
-sample document @file{circ.tex} is included in the distribution, but
-most documents including math and/or figures should do), you can use
-its menu or @kbd{C-c C-p C-d} (for @samp{Preview/Document}).
-Previews will now be generated for various objects in your document.
-You can use the time to take a short look at the other menu entries and
-key bindings in the @samp{Preview} menu.  You'll see the previewed
-objects change into a roadworks sign when @previewlatex{} has determined
-just what it is going to preview.  Note that you can freely navigate the
-buffer while this is going on.  When the process is finished you will
-see the objects typeset in your buffer.
-
-It is a bad idea, however, to edit the buffer before the roadworks signs
-appear, since that is the moment when the correlation between the
-original text and the buffer locations gets established.  If the buffer
-changes before that point of time, the previews will not be placed where
-they belong. If you do want to change some obvious error you just
-spotted, we recommend you stop the background process by pressing
-@kbd{C-c C-k}.
-
-To see/edit the @LaTeX{} code for a specific object, put the point (the
-cursor) on it and press @kbd{C-c C-p C-p} (for @samp{Preview/at point}).
-It will also do to click with the middle mouse button on the preview.
-Now you can edit the code, and generate a new preview by again pressing
-@kbd{C-c C-p C-p} (or by clicking with the middle mouse button on the
-icon before the edited text).
-
-If you are using the @code{desktop} package, previews will remain from
-one session to the next as long as you don't kill your buffer.
-
-@node Basic modes of operation, More documentation, Getting started, Introduction
-@section Basic modes of operation
-
-@previewlatex{} has a number of methods for generating its graphics.
-Its default operation is equivalent to using the `@LaTeX{}' command from
-@AUCTeX{}.  If this happens to be a call of PDF@LaTeX{} generating
-@acronym{PDF} output (you need at least @w{@AUCTeX{} 11.51} for this),
-then Ghostscript will be called directly on the resulting @acronym{PDF}
-file.  If a @acronym{DVI} file gets produced, first Dvips and then
-Ghostscript get called by default.
-
-The image type to be generated by Ghostscript can be configured with
-
-@example
-@kbd{M-x customize-option @key{RET} preview-image-type @key{RET}}
-@end example
-@vindex preview-image-type
-
-@noindent
-The default is @samp{png} (the most efficient image type).  A special
-setting is @samp{dvipng} in case you have the @samp{dvipng}
-@cindex Using dvipng
-@pindex dvipng
-program installed.  In this case, @samp{dvipng} will be used for
-converting @acronym{DVI} files and Ghostscript (with a @samp{PNG}
-device) for converting @acronym{PDF} files.  @samp{dvipng} is much
-faster than the combination of Dvips and Ghostscript.  You can get
-downloads, access to its @acronym{CVS} archive and further information
-from its @uref{https://savannah.nongnu.org/projects/dvipng, project
-site}.

-@item Support other formats than just @LaTeX{}
-
-plain @TeX{} users and @ConTeXt{} users should not have to feel left
-out.  While @ConTeXt{} is not supported yet by released versions of
-@AUCTeX{}, at least supporting plain would help people, and be a start
-for @ConTeXt{} as well.  There are plain-based formats like MusiX@TeX{}
-that could benefit a lot from @previewlatex{}.  The main part of the
-difficulties here is to adapt @file{preview.dtx} to produce stuff not
-requiring @LaTeX{}.
-
-@item Support nested snippets
-
-Currently you can't have both a footnote (which gets displayed as just
-its footnote number) and math inside of a footnote rendered as an image:
-such nesting might be achieved by rerunning @previewlatex{} on the
-footnote contents when one opens the footnote for editing.
-
-@item Support other text properties than just images
-
-Macros like @samp{\textit} can be rendered as images, but the resulting
-humungous blob is not suitable for editing, in particular since the
-line filling from LaTeX does not coincide with that of Emacs.  It would
-be much more useful if text properties just switched the relevant font
-to italics rather than replacing the whole text with an image.  It
-would also make editing quite easier.  Then there are things like
-footnotes that are currently just replaced by their footnote number.
-While editing is not a concern here (the number is not in the original
-text, anyway), it would save a lot of conversion time if no images were
-generated, but Emacs just displayed a properly fontified version of the
-footnote number.  Also, this might make @previewlatex{} useful even on
-text terminals.
-
-@item Find a way to facilitate Source Specials
-
-Probably in connection with adding appropriate support to
-@code{dvipng}, it would be nice if clicking on an image from a larger
-piece of source code would place the cursor at the respective source
-code location.
-
-@item Make @file{preview.dtx} look reasonable in @AUCTeX{}
-
-It is a bit embarrassing that @file{preview.dtx} is written in a manner
-that will not give either good syntax highlighting or good indentation
-when employing @AUCTeX{}.
-
-@item Web page work
-
-Currently, @previewlatex{}'s web page is not structured at all.  Better
-navigation would be desirable, as well as separate News and Errata eye
-catchers.
-
-@item Manual improvements
-
-@itemize @minus
-@item Pepper the manual with screen shots and graphics
-
-This will be of interest for the @acronym{HTML} and @TeX{} renditions
-of the texinfo manual.  Since Texinfo now supports images as well, this
-could well be nice to have.
-
-@item Fix duplicates
-
-Various stuff appears several times.
-
-@end itemize
-
-@item Implement rendering pipelines for Emacs
-
-The current @previewlatex{} interface is fundamentally flawed, not only
-because of a broken implementation.  A general batchable and
-daemonizable rendering infrastructure that can work on all kinds of
-preview images for embedding into buffers is warranted.  The current
-implementation has a rather adhoc flavor and is not easily extended.
-It will not work outside of @AUCTeX{}, either.
-
-@item Integrate into Ref@TeX{}
-
-When referencing to equations and the like, the preview-images of the
-source rather than plain text should be displayed.  If the preview in
-question covers labels, those should appear in the bubble help and/or a
-context menu.  Apropos:
-
-@item Implement @LaTeX{} error indicators
-
-Previews on erroneous @LaTeX{} passages might gain a red border or similar.
-
-@item Pop up relevant online documentation for frequent errors
-
-A lot of errors are of the ``badly configured'' variety.  Perhaps the
-relevant info pages should be delivered in addition to the error
-message.
-
-@item Implement a table editing mode where every table cell gets output
-as a separate preview.  Alternatively, output the complete table
-metrics in a way that lets people click on individual cells for editing
-purposes.
-
-@item Benchmark and kill Emacs inefficiencies
-
-Both the @LaTeX{} run under Emacs control as well as actual image
-insertion in Emacs could be faster.  CVS Emacs has improved in that
-respect, but it still is slower than desirable.
-
-@item Improve image support under Emacs
-
-The general image and color handling in Emacs is inefficient and partly
-defective.  This is still the case in CVS.  One option would be to
-replace the whole color and image handling with @acronym{GDK} routines
-when this library is available, since it has been optimized for it.

-@chapter Quick Start
-
-@AUCTeX{} is a powerful program offering many features and configuration
-options.  If you are new to @AUCTeX{} this might be deterrent.
-Fortunately you do not have to learn everything at once.  This Quick
-Start Guide will give you the knowledge of the most important commands
-and enable you to prepare your first @LaTeX{} document with @AUCTeX{}
-after only a few minutes of reading.
-
-In this introduction, we assume that @AUCTeX{} is already installed on
-your system.  If this is not the case, you should read the file
-@file{INSTALL} in the base directory of the unpacked distribution
-tarball.  These installation instructions are available in this manual
-as well, @ref{Installation}.  We also assume that you are familiar with
-the way keystrokes are written in Emacs manuals.  If not, have a look at
-the Emacs Tutorial in the Help menu.
-
-If @AUCTeX{} is installed in any other way than from the Emacs package
-manager (@acronym{ELPA}), you might still need to activate it, by
-inserting
-
-@lisp
-(load "auctex.el" nil t t)
-@end lisp
-@noindent
-in your user init file.@footnote{This usually is a file in your home
-directory called @file{.emacs}, or @file{.emacs.d/init.el}.}
-
-If @AUCTeX{} is installed from @acronym{ELPA}, the installation
-procedure already cares about loading @AUCTeX{} correctly and you
-@strong{must not} have the line above in your init file.  Note that this
-also applies if you have the following line in your init file
-
-@lisp
-(package-initialize)
-@end lisp
-
-In order to get support for many of the @LaTeX{} packages you will use
-in your documents, you should enable document parsing as well, which can
-be achieved by putting
-
-@lisp
-(setq TeX-auto-save t)
-(setq TeX-parse-self t)
-@end lisp
-@noindent
-into your init file.  Finally, if you often use @code{\include} or
-@code{\input}, you should make @AUCTeX{} aware of the multifile
-document structure.  You can do this by inserting
-
-@lisp
-(setq-default TeX-master nil)
-@end lisp
-
-into your init file.  Each time you open a new file, @AUCTeX{} will then
-ask you for a master file.

-You can disable it locally by typing @kbd{M-x font-lock-mode @key{RET}}.
-
-@AUCTeX{} will indent new lines to indicate their syntactical
-relationship to the surrounding text.  For example, the text of a
-@code{\footnote} or text inside of an environment will be indented
-relative to the text around it.  If the indenting has gotten wrong after
-adding or deleting some characters, use @key{TAB} to reindent the line,
-@kbd{M-q} for the whole paragraph, or @kbd{M-x LaTeX-fill-buffer @key{RET}}
-for the whole buffer.

-commands may be eased by using @kbd{C-c C-s}.  You will be asked for the

-@key{TAB} or @key{SPC} key to get a list of available level names, and
-to auto-complete what you started typing.  Next, you will be asked for
-the printed title of the section, and last you will be asked for a label
-to be associated with the section.
-
-@subsection Inserting environments
-
-Similarly, you can insert environments, that is
-@samp{\begin@{@}}--@samp{\end@{@}} pairs: Type @kbd{C-c C-e}, and select
-an environment type.  Again, you can use @key{TAB} or @key{SPC} to get a
-list, and to complete what you type.  Actually, the list will not only
-provide standard @LaTeX{} environments, but also take your
-@samp{\documentclass} and @samp{\usepackage} commands into account if
-you have parsing enabled by setting @code{TeX-parse-self} to @code{t}.
-If you use a couple of environments frequently, you can use the @key{up} and
-@key{down} arrow keys (or @kbd{M-p} and @kbd{M-n}) in the minibuffer to get
-back to the previously inserted commands.
-
-Some environments need additional arguments.  Often, @AUCTeX{} knows about
-this and asks you to enter a value. 
-
-@subsection Inserting macros
-
-@kbd{C-c C-m}, or simply @kbd{C-c RET} will give you a prompt that asks
-you for a @LaTeX{} macro.  You can use @key{TAB} for completion, or the
-@key{up}/@key{down} arrow keys (or @kbd{M-p} and @kbd{M-n}) to browse the command
-history.  In many cases, @AUCTeX{} knows which arguments a macro needs
-and will ask you for that.  It even can differentiate between mandatory
-and optional arguments---for details, see @ref{Completion}.
-
-An additional help for inserting macros is provided by the possibility
-to complete macros right in the buffer.  With point at the end of a
-partially written macro, you can complete it by typing @kbd{M-@key{TAB}}.
-
-@subsection Changing the font 
-
-@AUCTeX{} provides convenient keyboard shortcuts for inserting macros
-which specify the font to be used for typesetting certain parts of the
-text.  They start with @kbd{C-c C-f}, and the last @kbd{C-} combination
-tells @AUCTeX{} which font you want:
-
-@table @kbd
-@item C-c C-f C-b
-@kindex C-c C-f C-b
-@cindex @code{\textbf}
-Insert @b{bold face} @samp{\textbf@{@point{}@}} text.
-
-@item C-c C-f C-i
-@kindex C-c C-f C-i
-@cindex @code{\textit}
-Insert @i{italics} @samp{\textit@{@point{}@}} text.
-
-@item C-c C-f C-e
-@kindex C-c C-f C-e
-@cindex @code{\emph}
-Insert @emph{emphasized} @samp{\emph@{@point{}@}} text.
-
-@item C-c C-f C-s
-@kindex C-c C-f C-s
-@cindex @code{\textsl}
-Insert @slanted{slanted} @samp{\textsl@{@point{}@}} text.
-
-@item C-c C-f C-r
-@kindex C-c C-f C-r
-@cindex @code{\textrm}
-Insert @r{roman} @samp{\textrm@{@point{}@}} text.
-
-@item C-c C-f C-f
-@kindex C-c C-f C-f
-@cindex @code{\textsf}
-Insert  @sansserif{sans serif} @samp{\textsf@{@point{}@}} text.
-
-@item C-c C-f C-t
-@kindex C-c C-f C-t
-@cindex @code{\texttt}
-Insert @t{typewriter} @samp{\texttt@{@point{}@}} text.
-
-@item C-c C-f C-c
-@kindex C-c C-f C-c
-@cindex @code{\textsc}
-Insert @sc{small caps} @samp{\textsc@{@point{}@}} text.
-
-@item C-c C-f C-d
-@kindex C-c C-f C-c
-@cindex Deleting fonts
-Delete the innermost font specification containing point.
-
-@end table
-
-If you want to change font attributes of existing text, mark it as an
-active region, and then invoke the commands.  If no region is selected,
-the command will be inserted with empty braces, and you can start typing
-the changed text.
-
-Most of those commands will also work in math mode, but then macros like
-@code{\mathbf} will be inserted.
-
-
-@subsection Other useful features
-
-@AUCTeX{} also tries to help you when inserting the right ``quote''
-signs for your language, dollar signs to typeset math, or pairs of
-braces.  It offers shortcuts for commenting out text (@kbd{C-c ;} for
-the current region or @kbd{C-c %} for the paragraph you are in).  The
-same keystrokes will remove the % signs, if the region or paragraph is
-commented out yet.  With @code{TeX-fold-mode}, you can hide certain
-parts (like footnotes, references etc.)@: that you do not edit currently.
-Support for Emacs' outline mode is provided as well.  And there's more,
-but this is beyond the scope of this Quick Start Guide.
-
-
-
-@node Processing Facilities
-@section Creating and viewing output, debugging
-
-@subsection One Command for @LaTeX{}, helpers, viewers, and printing
-
-If you have typed some text and want to run @LaTeX{} (or @TeX{}, or
-other programs---see below) on it, type @kbd{C-c C-c}.  If applicable,
-you will be asked whether you want to save changes, and which program
-you want to invoke.  In many cases, the choice that @AUCTeX{} suggests
-will be just what you want: first @command{latex}, then a viewer.  If a
-@command{latex} run produces or changes input files for
-@command{makeindex}, the next suggestion will be to run that program,
-and @AUCTeX{} knows that you need to run @command{latex} again
-afterwards---the same holds for Bib@TeX{}.
-
-When no processor invocation is necessary anymore, @AUCTeX{} will
-suggest to run a viewer, or you can chose to create a PostScript file
-using @command{dvips}, or to directly print it.
-
-Actually, there is another command which comes in handy to compile
-documents: type @kbd{C-c C-a} (@code{TeX-command-run-all}) and @AUCTeX{}
-will compile the document for you until it is ready and then run the
-viewer.  This is the same as issuing repeatedly @kbd{C-c C-c} and
-letting @AUCTeX{} guess the next command to run.
-
-At this place, a warning needs to be given: First, although @AUCTeX{} is
-really good in detecting the standard situations when an additional
-@command{latex} run is necessary, it cannot detect it always.  Second,
-the creation of PostScript files or direct printing currently only works
-when your output file is a @acronym{DVI} file, not a @acronym{PDF} file.
-
-Ah, you didn't know you can do both?  That brings us to the next topic.
-
-@subsection Choosing an output format
-
-From a @LaTeX{} file, you can produce @acronym{DVI} output, or a
-@acronym{PDF} file directly @i{via} @command{pdflatex}.  You can switch
-on source specials for easier navigation in the output file, or tell
-@command{latex} to stop after an error (usually @option{--noninteractive}
-is used, to allow you to detect all errors in a single run).
-
-These options are controlled by toggles, the keystrokes should be easy
-to memorize:
-
-@table @kbd
-@item C-c C-t C-p
-@kindex C-c C-t C-p
-This command toggles between @acronym{DVI} and @acronym{PDF} output
-
-@item C-c C-t C-i
-@kindex C-c C-t C-i
-toggles interactive mode
-
-@item C-c C-t C-s
-@kindex C-c C-t C-s
-toggles Sync@TeX{} (or source specials) support
-
-@item C-c C-t C-o
-@kindex C-c C-t C-o
-toggles usage of Omega/lambda.
-
-@end table
-
-There is also another possibility: compile the document with
-@command{tex} (or @command{latex}) and then convert the resulting
-@acronym{DVI} file to @acronym{PDF} using
-@command{dvips}--@command{ps2pdf} sequence or @command{dvipdfmx} command.
-If you want to go by this route, customize @code{TeX-PDF-from-DVI} option.
-Then @AUCTeX{} will suggest you to run the appropriate command when
-you type @kbd{C-C C-c}.  For details, see @ref{Processor Options}.
-
-@subsection Debugging @LaTeX{}
-
-When @AUCTeX{} runs a program, it creates an output buffer in which it
-displays the output of the command.  If there is a syntactical error in
-your file, @command{latex} will not complete successfully. @AUCTeX{}
-will tell you that, and you can get to the place where the first error
-occured by pressing @kbd{C-c `} (the last character is a backtick).  The
-view will be split in two windows, the output will be displayed in the
-lower buffer, and both buffers will be centered around the place where
-the error ocurred.  You can then try to fix it in the document buffer,
-and use the same keystrokes to get to the next error.  This procedure
-may be repeated until all errors have been dealt with.  By pressing
-@kbd{C-c C-w} (@code{TeX-toggle-debug-boxes}) you can toggle whether
-@AUCTeX{} should notify you of overfull and underfull boxes in addition
-to regular errors.
-
-Issue @kbd{M-x TeX-error-overview @key{RET}} to see a nicely formatted list of
-all errors and warnings reported by the compiler.
-
-If a command got stuck in a seemingly infinite loop, or you want to stop
-execution for other reasons, you can use @kbd{C-c C-k} (for ``kill'').
-Similar to @kbd{C-l}, which centers the buffer you are in around your
-current position, @kbd{C-c C-l} centers the output buffer so that the
-last lines added at the bottom become visible.
-
-@subsection Running @LaTeX{} on parts of your document
-
-If you want to check how some part of your text looks like, and do not
-want to wait until the whole document has been typeset, then mark it as
-a region and use @kbd{C-c C-r}.  It behaves just like @kbd{C-c C-c}, but
-it only uses the document preamble and the region you marked.
-
-If you are using @code{\include} or @code{\input} to structure your
-document, try @kbd{C-c C-b} while you are editing one of the included
-files.  It will run @command{latex} only on the current buffer, using the
-preamble from the master file.

-\title{\previewlatex}
-\section{Activation}
-\previewlatex\ is part of AUC\TeX.  If it is active, you should see an
-entry ``Preview'' in the menu bar when editing \LaTeX{} files.  If you
-have a ``LaTeX'', but no ``Preview'' menu, add the following to your
-init file (usually \file{\string~/.emacs.d/init.el}):
-\beginexample
-(load "preview-latex.el" nil t t)
-\endexample
-
-\section{Usage and keybindings}
-\previewlatex\ operation only affects the display of the buffer, not
-its contents.  It runs only on demand, using the target {\sc dvi} or
-{\sc PDF} files in the process.  The first command in the following
-list (also on the toolbar button) will (as applicable) repreview an
-active region or a single modified preview, toggle the visibility of
-an unmodified preview or generate previews for a surrounding buffer
-area up to the next preview.
-
-\key{Preview at point}{C-c C-p C-p}
-\key{Preview environment}{C-c C-p C-e}
-\key{Preview region}{C-c C-p C-r}
-\key{Preview buffer}{C-c C-p C-b}
-\key{Preview document}{C-c C-p C-d}
-\key{Remove previews at point}{C-c C-p C-c C-p}
-\key{Remove previews from region}{C-c C-p C-c C-r}
-\key{Remove previews from buffer}{C-c C-p C-c C-b}
-\key{Remove previews from document}{C-c C-p C-c C-d}
-\key{Cache preamble}{C-c C-p C-f}
-\key{Switch off preamble cache}{C-c C-p C-c C-f}
-\key{Read Texinfo manual}{C-c C-p TAB}
-\key{Copy region as MML}{C-c C-p C-w}
-
-The last keysequence will copy a region with previews into the kill
-ring in a form fit for sending in Emacs' {\tt message-mode}.
-
-\section{Customization within Emacs}
-
-You can use \kbd{M-x customize-variable RET} or the ``Preview\slash
-Customize'' menu for customization.  Worthwhile settings:
-
-\halign to \hsize{\tabskip=1ptplus1fil\relax#\hfil&\hfil\var{#}\tabskip0pt\cr
-\noalign{\medskip If you have dvipng available:}
-Set to \kbd{dvipng}&preview-image-type\cr
-\noalign{\medskip \vbox{Keep counter values when regenerating
-  single previews:}}
-Set to \kbd{t}&preview-preserve-counters\cr
-\noalign{\medskip \vbox{Cache/Don't cache preamble without query
-(preamble caching is done using \file{mylatex.ltx} and might not always
-work.  Use the appropriate key sequences for overriding the following
-setting):}}
-Set to \kbd{t}/\kbd{nil}&preview-auto-cache-preamble\cr}
-
-\section{Customization from \LaTeX{}}
-Customization is done in the document preamble (you need to load
-\file{preview.sty} explicitly) or in \file{prauctex.cfg} (which should
-load the system \file{prauctex.cfg} first).  Commands:
-
-\halign to \hsize{\tabskip=1ptplus1fil\relax#\hfil&\hfil\kbd{#}\tabskip0pt\cr
-Preview macro&\string\PreviewMacro[\{\<args>\}]\{\<macro>\}\cr
-Preview env&\string\PreviewEnvironment[\{\<args>\}]\{\<env>\}\cr
-Skip macro&\string\PreviewMacro*[\{\<args>\}]\{\<macro>\}\cr
-Skip env&\string\PreviewEnvironment*[\{\<args>\}]\{\<env>\}\cr
-\noalign{\smallskip Diverting material from float environments}
-Snarf stuff&\string\PreviewSnarfEnvironment[\{\<args>\}]\{\<env>\}\cr
-}
-
-Values to be used within \<args>:
-\halign to
-\hsize{\tabskip=1ptplus1fil\relax#\hfil&\hfil\kbd{#}\tabskip0pt\cr
-Optional argument&[]\cr
-Mandatory argument&\{\}\cr

-\title{Outlining \TeX\ Documents}
-
-AUC\TeX\ supports outline mode by defining section, subsection,
-etc. as heading levels. You can use \kbd{M-x outline-minor-mode RET}
-to toggle outline minor mode. All outline minor mode commands are
-under the prefix key specified by \var{outline-minor-mode-prefix}, default

-\key{Select this item}{RET}
-\key{Rescan the document}{r}
-\key{Display location in other window}{SPC}
-\key{Follow mode}{f}
-
-\section{Multifile actions}
-Since RefTeX scans the entire (multifile) document, it can provide
-commands that act on all files of a document.  Check the \kbd{

-@itemize @bullet
-@item Integration of @previewlatex{} into @AUCTeX{}
-
-As of @AUCTeX{} 11.81 @previewlatex{} is a part of @AUCTeX{} in the
-sense that the installation routines were merged and @previewlatex{} is
-being packaged with @AUCTeX{}.
-
-Further integration will happen at the backend.  This involves folding
-of error parsing and task management of both packages which will ease
-development efforts and avoid redundant work.
-
-@item Error help catalogs
-
-Currently, the help for errors is more or less hardwired into
-@file{latex.el}.  For supporting error help in other languages, it would
-be sensible to instead arrange error messages in language-specific
-files, make a common info file from all such catalogs in a given
-language and look the error texts up in an appropriate index.  The user
-would then specify a preference list of languages, and the errors would
-be looked up in the catalogs in sequence until they were identified.
-
-@item Combining @samp{docTeX} with Ref@TeX{}
-
-Macro cross references should also be usable for document navigation
-using Ref@TeX{}.
-
-@item Fix remove-style feature
-
-Currently @code{TeX-remove-style} implementation isn't good.  It is common
-practice that major mode functions directly add macros and environments
-via @code{TeX-add-symbols} and @code{LaTeX-add-environments}, but those
-macros and environments are lost once @code{TeX-remove-style} runs.  It is
-necessary to run major mode function, by e.g.@: @code{normal-mode}, again
-to recover them, but that makes no point in running
-@code{TeX-remove-style} itself because major mode function kills all
-buffer-local variables.
-
-As of @AUCTeX{} 12.3, @code{TeX-remove-style} is no longer used by any
-other codes.
-
-@item
-Document @code{LaTeX-insert-into-commments},
-@code{TeX-translate-location-hook}, and usage of @ConTeXt{} mode.
-@end itemize
-
-@node Wishlist
-@section Wishlist
-
-@itemize @bullet
-@item
-Simplify tool bar implementation.  The library @file{toolbar-x.el} was
-developed as an abstraction layer to absorb difference between XEmacs
-and @acronym{GNU} Emacs.  Now that XEmacs is no longer supported, the
-library, together with @file{tex-bar.el} as a whole, can be much
-simplified (or even unified).
-
-@item Documentation lookup for macros
-
-A parser could gather information about which macros are defined in
-which @LaTeX{} packages and store the information in a hashtable which
-can be used in a backend for @code{TeX-doc} in order to open the
-matching documentation for a given macro.  The information could also be
-used to insert an appropriate @samp{\usepackage} statement if the user
-tries to insert a macro for which the respective package has not been
-requested yet.
-
-@item Improvements to error reporting
-
-Fringe indicators for errors in the main text would be nice.
-
-@item A math entry grid
-
-A separate frame with a table of math character graphics to click on in
-order to insert the respective sequence into the buffer (cf. the
-``grid'' of @samp{x-symbol}).
-
-@item Crossreferencing support
-
-It would be nice if you could index process your favorite collection of
-@file{.dtx} files (such as the @LaTeX{} source), just call a command on
-arbitrary control sequence, and get either the @acronym{DVI} viewer opened right
-at the definition of that macro (using Source Specials), or the source
-code of the @file{.dtx} file.
-
-@item Better plain @TeX{} support
-
-For starters, @code{LaTeX-math-mode} is not very @LaTeX{}-specific in
-the first place, and similar holds for indentation and formatting.
-
-@item
-Page count when compiling should (optionally) go to modeline of the
-window where the compilation command was invoked, instead of the output
-window.  Suggested by Karsten Tinnefeld
-@email{tinnefeld@@irb.informatik.uni-dortmund.de}.
-
-@item
-Command to insert a macrodefinition in the preamble, without moving
-point from the current location.  Suggested by
-"Jeffrey C. Ely" @email{ely@@nwu.edu}.
-
-@item
-A database of all commands defined in all stylefiles.  When a command or
-environment gets entered that is provided in one of the styles, insert
-the appropriate @code{\usepackage} in the preamble.
-
-@item
-A way to add and overwrite math mode entries in style files, and to
-decide where they should be.  Suggested by Remo Badii @email{Remo.Badii@@psi.ch}.
-
-@item
-Create template for (first) line of tabular environment.
-
-@item
-@c FIXME: Already fixed?
-I think prompting for the master is the intended behaviour.  It
-corresponds to a `shared' value for @code{TeX-master}.
-
-There should probably be a `none' value which wouldn't query for the
-master, but instead disable all features that relies on @code{TeX-master}.
-
-This default value for @code{TeX-master} could then be controled with mapping
-based on the extension.
-
-@item
-Use index files (when available) to speed up @kbd{C-c C-m include
-@key{RET}}.
-
-@item
-Option not to calculate very slow completions like for
-@kbd{C-c C-m include @key{RET}}.
-
-@item
-Font menu should be created from @code{TeX-font-list}.
-
-@item
-Installation procedure written purely in emacs lisp.
-
-@item
-Included PostScript files should also be counted as part of the
-document.
-
-@item
-A nice hierarchical by-topic organization of all officially documented
-@LaTeX{} macros, available from the menu bar.
-
-@item
-@code{TeX-command-default} should be set from the master file, if not
-set locally.  Suggested by Peter Whaite @email{peta@@cim.mcgill.ca}.
-
-@item
-Make @AUCTeX{} work with @samp{crypt++}.  Suggested by Chris Moore
-@email{Chris.Moore@@src.bae.co.uk}.
-
-@item
-Make @AUCTeX{} work with @samp{longlines}.  This would also apply to
-@previewlatex{}, though it might make sense to unify error processing
-before attempting this.
-
-@item
-@c FIXME: Already achieved?
-The @samp{Spell} command should apply to all files in a document.  Maybe
-it could try to restrict to files that have been modified since last
-spell check?  Suggested by Ravinder Bhumbla @email{rbhumbla@@ucsd.edu}.
-
-@item
-Make @key{.} check for abbreviations and sentences ending with capital
-letters.
-
-@item
-Use Emacs 19 minibuffer history to choose between previewers, and other
-stuff.  Suggested by John Interrante
-@email{interran@@uluru.Stanford.EDU}.
-

-Documentation of variables that can be set in a style hook.

-
-At least, support headers, trailers, as well as @code{TeX-outline-extra}.
-
-@item
-@code{TeX-header-start} and @code{TeX-trailer-end}.
-
-We might want these, just for fun (and outlines)
-
-@item
-Plain @TeX{} and @LaTeX{} specific header and trailer expressions.
-
-We should have a way to globally specify the default value of the header
-and trailer regexps.
-
-@item
-Get closer to original @code{TeX-mode} keybindings.
-
-A third initialization file (@file{tex-mode.el}) containing an emulator
-of the standard @code{TeX-mode} would help convince some people to
-change to @AUCTeX{}.
-
-@item
-Use markers in @code{TeX-error-list} to remember buffer positions in
-order to be more robust with regard to line numbers and changed files.
-
-@item
-Finish the Texinfo mode.  For one thing, many Texinfo mode commands do
-not accept braces around their arguments.

-
-The following are brief installation instructions for the impatient.  In
-case you don't understand some of this, run into trouble of some sort,
-or need more elaborate information, refer to the detailed instructions
-further below.
-
-@enumerate
-@item
-Install the prerequisites, i.e.@: GNU Emacs, MSYS or Cygwin, a @TeX{}
-system, and Ghostscript.
-
-@item
-Open the MSYS shell or a Cygwin shell and change to the directory
-containing the unzipped file contents.
-
-@item
-Configure @AUCTeX{}:
-
-For Emacs: Many people like to install @AUCTeX{} into the pseudo file
-system hierarchy set up by the Emacs installation.  Assuming Emacs is
-installed in @file{C:/Program Files/Emacs} and the directory for local
-additions of your @TeX{} system, e.g.@: MiK@TeX{}, is
-@file{C:/localtexmf}, you can do this by typing the following statement
-at the shell prompt:
-
-@example
-./configure --prefix='C:/Program Files/Emacs' \
-  --infodir='C:/Program Files/Emacs/info' \
-  --with-texmf-dir='C:/localtexmf'
-@end example
-
-The commands above is example for common usage.  More on configuration
-options can be found in the detailed installation instructions below.
-
-If the configuration script failed to find all required programs, make
-sure that these programs are in your system path and add directories
-containing the programs to the @env{PATH} environment variable if
-necessary.  Here is how to do that in W2000/XP:
-
-@enumerate
-@cindex Adding to @env{PATH} in Windows
-@cindex @env{PATH} in Windows
-@item
-On the desktop, right click ``My Computer'' and select properties.
-@item
-Click on ``Advanced'' in the ``System Properties'' window.
-@item
-Select ``Environment Variables''.
-@item

-@subheading Detailed Installation Instructions
-
-Installation of @AUCTeX{} under Windows is in itself not more
-complicated than on other platforms.  However, meeting the prerequisites
-might require more work than on some other platforms, and feel less
-natural.
-
-If you are experiencing any problems, even if you think they are of your
-own making, be sure to report them to @email{auctex-devel@@gnu.org} so
-that we can explain things better in future.
-
-Windows is a problematic platform for installation scripts.  The main
-problem is that the installation procedure requires consistent file
-names in order to find its way in the directory hierarchy, and Windows
-path names are a mess.
-
-The installation procedure tries finding stuff in system search paths
-and in Emacs paths.  For that to succeed, you have to use the same
-syntax and spelling and case of paths everywhere: in your system search
-paths, in Emacs' @code{load-path} variable, as argument to the scripts.
-If your path names contain spaces or other `shell-unfriendly'
-characters, most notably backslashes for directory separators, place the
-whole path in @samp{"double quote marks"} whenever you specify it on a
-command line.
-
-Avoid `helpful' magic file names like @samp{/cygdrive/c} and
-@samp{C:\PROGRA~1\} like the plague.  It is quite unlikely that the
-scripts will be able to identify the actual file names involved.  Use
-the full paths, making use of normal Windows drive letters like
-@samp{ 'C:/Program Files/Emacs' } where required, and using the same
-combination of upper- and lowercase letters as in the actual files.
-File names containing shell-special characters like spaces or
-backslashes (if you prefer that syntax) need to get properly quoted to
-the shell: the above example used single quotes for that.
-
-Ok, now here are the steps to perform:
-
-@enumerate
-@item
-You need to unpack the @AUCTeX{} distribution (which you seemingly have
-done since you are reading this).  It must be unpacked in a separate
-installation directory outside of your Emacs file hierarchy: the
-installation will later copy all necessary files to their final
-destination, and you can ultimately remove the directory where you
-unpacked the files.
-
-Line endings are a problem under Windows.  The distribution contains
-only text files, and theoretically most of the involved tools should get
-along with that.  However, the files are processed by various utilities,
-and it is conceivable that not all of them will use the same line ending
-conventions.  If you encounter problems, it might help if you try
-unpacking (or checking out) the files in binary mode, if your tools
-allow that.
-
-If you don't have a suitable unpacking tool, skip to the next step: this
-should provide you with a working @samp{unzip} command.
-
-@item
-The installation of @AUCTeX{} will require the MSYS tool set from
-@uref{http://www.mingw.org/} or the Cygwin tool set from
-@uref{https://cygwin.com/}.  The latter is slower and larger (the download
-size of the base system is about 15 MB) but comes with a package manager
-that allows for updating the tool set and installing additional packages
-like, for example, the spell checker @w{aspell}.
-
-If Cygwin specific paths like @samp{/cygdrive/c} crop up in the course
-of the installation, using a non-Cygwin Emacs could conceivably cause
-trouble.  Using Cygwin either for everything or nothing might save
-headaches, @emph{if} things don't work out.
-
-@item
-Install a current version of @w{Emacs} from
-@uref{https://ftp.gnu.org/gnu/emacs/windows/}.
-
-@item
-You need a working @TeX{} installation.  One popular installation under
-Windows is @uref{https://miktex.org/,MiK@TeX{}}.  Another much more
-extensive system is @uref{https://www.tug.org/texlive/,@w{@TeX{} Live}}
-which is rather close to its Unix cousins.
-
-@item
-A working copy of @uref{https://www.ghostscript.com/,Ghostscript} is
-required for @previewlatex{} operation.  Examining the output from
-@example
-gswin32c -h
-@end example
-on a Windows command line should tell you whether your Ghostscript
-supports the @code{png16m} device needed for @acronym{PNG} support.
-MiK@TeX{} apparently comes with its own Ghostscript called @file{mgs.exe}.
-
-@item
-@uref{https://www.perl.org/,Perl} is needed for rebuilding the
-documentation if you are working with a copy from Git or have
-touched documentation source files in the @previewlatex{} part.  If the
-line endings of the file @file{preview/latex/preview.dtx} don't
-correspond with what Perl calls @code{\n} when reading text files,
-you'll run into trouble.
-
-@item
-Now the fun stuff starts.  If you have not yet done so, unpack the
-@AUCTeX{} distribution into a separate directory after rereading the
-instructions for unpacking above.
-
-@item
-Ready for takeoff.  Start some shell (typically @command{bash}) capable of
-running @command{configure}, change into the installation directory and
-call @command{./configure} with appropriate options.
-
-Typical options you'll want to specify will be
-@table @code
-@item --prefix=@var{drive:/path/to/emacs-hierarchy}
-which tells @command{configure} where to perform the installation.  It may
-also make @command{configure} find Emacs automatically; if this doesn't
-happen, try @option{--with-emacs} as described below.  All automatic
-detection of files and directories restricts itself to directories below
-the @var{prefix} or in the same hierarchy as the program accessing the
-files.  Usually, directories like @file{man}, @file{share} and
-@file{bin} will be situated right under @var{prefix}.
-
-This option also affects the defaults for placing the Texinfo
-documentation files (see also @option{--infodir} below) and automatically
-generated style hooks.
-
-If you have a central directory hierarchy (not untypical with Cygwin)
-for such stuff, you might want to specify its root here.  You stand a
-good chance that this will be the only option you need to supply, as
-long as your @TeX{}-related executables are in your system path, which
-they better be for @AUCTeX{}'s operation, anyway.
-
-@item --with-emacs
-if you are installing for a version of Emacs.  You can use
-@samp{--with-emacs=@var{drive:/path/to/emacs}} to specify the name of the
-installed Emacs executable, complete with its path if necessary (if
-Emacs is not within a directory specified in your @env{PATH} environment
-setting).
-
-@item --with-lispdir=@var{drive:/path/to/site-lisp}
-This option tells a place in @code{load-path} below which the
-files are situated.  The startup files @file{auctex.el} and
-@file{preview-latex.el} will get installed here unless a subdirectory
-@file{site-start.d} exists which will then be used instead.  The other
-files from @AUCTeX{} will be installed in a subdirectory called
-@file{auctex}.
-
-If you think that you need a different setup, please refer to the full
-installation instructions in
-@ifset rawfile
-the @file{INSTALL} file.
-@end ifset
-@ifclear rawfile
-@ref{Configure}.
-@end ifclear
-
-@item --infodir=@var{drive:/path/to/info/directory}
-If you are installing into an Emacs directory, info files have to be put
-into the @file{info} folder below that directory.  The configuration
-script will usually try to install into the folder @file{share/info}, so
-you have to override this by specifying something like
-@samp{--infodir='C:/Program Files/info'} for the configure call.
-
-@item --with-auto-dir=@var{drive:/dir}
-Directory containing automatically generated information.  You should
-not normally need to set this, as @samp{--prefix} should take care of
-this.
-
-@item --disable-preview
-Use this option if your Emacs version is unable to support image
-display.
-
-@item --with-texmf-dir=@var{drive:/dir}
-This will specify the directory where your @TeX{} installation sits.  If
-your @TeX{} installation does not conform to the @acronym{TDS} (@TeX{} directory
-standard), you may need to specify more options to get everything in
-place.
-@end table
-
-For more information about any of the above and additional options, see
-@ifset rawfile
-the `Configure' section in the @file{INSTALL} file.
-@end ifset
-@ifclear rawfile
-@ref{Configure}.
-@end ifclear
-
-@c FIXME: It seems this no longer holds.
-@c Calling
-@c @file{./configure --help=recursive}
-@c will tell about other options, but those are almost never required.
-
-Some executables might not be found in your path.  That is not a good
-idea, but you can get around by specifying environment variables to
-@command{configure}:
-@example
-GS="@var{drive:/path/to/gswin32c.exe}" ./configure @dots{}
-@end example
-should work for this purpose.  @file{gswin32c.exe} is the usual name for
-the required @emph{command line} executable under Windows; in contrast,
-@file{gswin32.exe} is likely to fail.
-
-As an alternative to specifying variables for the @command{configure} call
-you can add directories containing the required executables to the
-@env{PATH} variable of your Windows system.  This is especially a good
-idea if Emacs has trouble finding the respective programs later during
-normal operation.
-
-@item
-Run @command{make} in the installation directory.
-	
-@item
-Run @code{make install} in the installation directory.
-
-@item
-With Emacs, activation of @AUCTeX{} and @previewlatex{} depends on a
-working @file{site-start.d} directory or similar setup, since then the
-startup files @file{auctex.el} and @file{preview-latex.el} will have
-been placed there.  If this has not been done, you should be able to
-load the startup files manually with
-@lisp
-(load "auctex.el" nil t t)
-(load "preview-latex.el" nil t t)
-@end lisp
-in either a site-wide @file{site-start.el} or your personal startup file
-(usually accessible as @file{~/.emacs} or @file{~/.emacs.d/init.el} from
-within Emacs).
-
-@cindex @file{tex-mik.el}
-The default configuration of @AUCTeX{} is probably not the best fit for
-Windows systems with MiK@TeX{}.  You might want to add
-@lisp
-(require 'tex-mik)
-@end lisp
-after loading @file{auctex.el} and @file{preview-latex.el} in order to
-get more appropriate values for some customization options.
-
-You can always use
-
-@example
-@kbd{M-x customize-group @key{RET} AUCTeX @key{RET}}
-@end example
-
-in order to customize more stuff, or use the @samp{Customize} menu.
-
-@item
-Load @file{circ.tex} into Emacs and see if you get the @samp{Command}
-menu.  Try using it to @LaTeX{} the file.
-
-@item
-Check whether the @samp{Preview} menu is available in this file.  Use it
-to generate previews for the document.
-
-If this barfs and tells you that image type @samp{png} is not supported,
-you can either add @acronym{PNG} support to your Emacs installation or
-choose another image format to be used by @previewlatex{}.
-
-Adding support for an image format usually involves the installation of
-a library, e.g.@: from @uref{http://gnuwin32.sf.net/}.  If you got your
-Emacs from @uref{https://www.gnu.org/} you might want to check its
-@uref{https://ftp.gnu.org/gnu/emacs/windows/README,README file} for
-details.
-
-A different image format can be chosen by setting the variable
-@code{preview-image-type}.  While it is recommended to keep the
-@samp{dvipng} or @samp{png} setting, you can temporarily select a
-different format like @samp{pnm} to check if the lack of @acronym{PNG}
-support is the only problem with your Emacs installation.
-
-Try adding the line
-
-@lisp
-(setq preview-image-type 'pnm)
-@end lisp
-
-to your init file for a quick test.  You should remove the line after
-the test again, because @acronym{PNM} files take away @strong{vast}
-amounts of disk space, and thus also of load/save time.
-@end enumerate
-
-Well, that about is all.  Have fun!
