+@top AUC @TeX{}
+ 
+AUC @TeX{} is an integrated environment for editing La@TeX{} and
+@TeX{} files.@refill
+
+This file documents AUC @TeX{} version 9.7.
+
+Although AUC @TeX{} contains a large number of features, there are no
+reasons to despair.  You can continue to write @TeX{} and La@TeX{}
+documents the way you are used to, and only start using the multiple
+features in small steps.  AUC @TeX{} 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.
+
+If you want to make AUC TeX aware of style files and multi-file
+documents right away, 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
+
+NOTE: This documentation is preliminary.  It should however cover most
+important points.  Corrections or perhaps rewrites of sections
+are VERY WELCOME.@refill

+The most commonly used commands/macros of AUC @TeX{} are those which
+simply insert templates for often used @TeX{} and/or La@TeX{}
+constructs, like font changes, handling of environments, etc.

+@cindex Brackets
+@cindex Dollars
+@cindex Math mode delimiters
+@cindex Matching dollar signs
+@cindex Display math mode
+
+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, AUC @TeX{} 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.@refill
+@end deffn
+
+@defopt TeX-open-quote
+String inserted by typing @kbd{"} to open a quotation.
+@end defopt
+
+@defopt TeX-close-quote
+String inserted by typing @kbd{"} to open a quotation.
+@end defopt
+
+If you include the style file @file{german} @code{TeX-open-quote} and
+@code{TeX-close-quote} will both be set to @samp{"}.
+
+In AUC @TeX{}, dollar signs should match like they do in @TeX{}.  This
+has been partially implemented, we assume dollar signs always match
+within a paragraph.  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.  If you enter a dollar sign that matches a double dollar sign
+@samp{$$} AUC @TeX{} will automatically insert two dollar signs.  If you
+enter a second dollar sign that matches a single dollar sign, the single
+dollar sign will automatically be converted to a double 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.  
+Ensure double dollar signs match up correctly by inserting extra
+dollar signs when needed.
+
+With optional @var{arg}, insert that many dollar signs.
+@end deffn
+
+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.

+@cindex Changing font
+@cindex Specifying a font
+
+Perhaps the most used keyboard commands of AUC @TeX{} are the short-cuts
+available for easy insertion of font changing macros.  They all put the
+font change inside a @TeX{} group, a practice that help preventing
+subtle errors.  The most significant advantage of using these command
+instead of typing it in yourself, is that the braces will always match
+correctly.  
+
+If you give an argument (that is, type @kbd{C-u}) to the font command,
+the innermost font will be replaced, i.e. the font in the @TeX{} group
+around point will be changed.  The following table shows the available
+commands, with @code{@point{}} indicating the position where the text
+will be inserted.@refill

+A large apparatus is available that supports insertions of environments,
+that is @samp{\begin@{@}} --- @samp{\end@{@}} pairs.
+
+AUC @TeX{} is aware of most of the actual environments available in a
+specific document.  This is achieved by examining your
+@samp{\documentstyle} command, and consulting a precompiled list of
+environments available in a large number of styles.
+
+You insert an environment with @kbd{C-c C-e}, and select an environment
+type.  Depending on the environment, AUC @TeX{} 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})  AUC @TeX{} 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 AUC @TeX{} may
+prompt you for further specifications.  
+
+If the optional argument @var{arg} is not-nil (i.e. you have given a
+prefix argument), the current environment is modified and no new
+environment is inserted.

+Default environment to insert when invoking @samp{LaTeX-environment}
+first time.

+@cindex Arguments to @TeX{} macros
+
+Emacs lisp programmers probably know the @code{lisp-complete-symbol}
+command, usually bound to @kbd{M-@key{TAB}}.  Users of the wonderful
+ispell mode know and love the @code{ispell-complete-word} command from
+that package.  Similarly, AUC @TeX{} has a @code{TeX-complete-symbol}
+command, usually bound to @kbd{M-@key{TAB}}.  Using
+@code{LaTeX-complete-symbol} makes it easier to type and remember the
+names of long La@TeX{} macros.
+ 
+In order to use @code{TeX-complete-symbol}, you should write a backslash
+and the start of the macro.  Typing @kbd{M-@key{TAB}} will now
+complete as much of the macro, as it unambiguously can.  For example, if
+you type `@samp{\renewc}' and then `@kbd{M-@key{TAB}}, it will expand
+to `@samp{\renewcommand}'.
+ 
+@deffn Command TeX-complete-symbol
+@kindex M-@key{TAB}
+(@kbd{M-@key{TAB}})  Complete @TeX{} symbol before point.
+@end deffn
+
+A more direct way to insert a macro is with @code{TeX-insert-macro},
+bound to @kbd{C-c C-m}.  It has the advantage over completion that it
+knows about the argument of most standard La@TeX{} 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}) Prompt (with completion) for the name of a @TeX{} macro,
+and if AUC @TeX{} knows the macro, prompt for each argument.
+@end deffn
+
+As a default selection, AUC @TeX{} 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
+
+A faster alternative is to bind the function @code{TeX-electric-macro}
+to @samp{\}.  This can be done by setting the variable @code{TeX-electric-escape}
+
+@defopt TeX-electric-escape
+If this is non-nil when AUC @TeX{} is loaded, the @TeX{} escape
+character @samp{\} will be bound to @code{TeX-electric-macro}
+@end defopt
+
+The difference between @code{TeX-insert-macro} and
+@code{TeX-electric-macro} is that space 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 AUC @TeX{} knows the macro, prompt for each argument.
+Space will complete and exit.
+@end deffn
+
+By default AUC @TeX{} will put an empty set braces @samp{@{@}} after a
+macro with no arguments to stop it from eating the next whitespace.
+This can be stopped by entering @code{LaTeX-math-mode},
+@pxref{Mathematics}, or 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.

+@code{TeX-insert-macro} or @code{TeX-electric-macro}, and Bib@TeX{}
+entries when you enter a @samp{\cite} macro.  For this kind of
+completion to work, parsing must be enabled as described in

+It is often necessary to comment out temporarily a region of @TeX{} or

+@cindex Reindenting
+
+AUC @TeX{} contains very advanced handling of indentation and
+reformatting of the La@TeX{} source.  If you have already tried AUC
+@TeX{} with @code{auto-fill-mode} enabled, you may have noted that the
+source is automatically indented and formatted as you write it.  More
+over, AUC @TeX{} is able to format sections of text on demand.
+
+It is important to realize, that AUC @TeX{} comes with `formatting' in
+two fashions.  Either letting @TeX{} format the file, or letting AUC
+@TeX{} make the ASCII document look better.
+
+Indentation is done by La@TeX{} 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.  This indentation makes it easier to see the
+structure of the document, and to catch errors such as a missing close
+brace.  Thus, the indentation is done for precisely the same reasons
+that you would indent ordinary computer programs.
+@vindex LaTeX-indent-level
+@vindex LaTeX-item-indent
+
+The following is a short sample of an itemize environment indented by
+AUC @TeX{}.  If more environment are nested, they are indented
+`accumulated' just like most programming languages usually are seen
+indented in nested constructs.
+
+@example
+\begin@{itemize@}
+\item Insertion of templates for logical-structural compositions such as
+  environments and sections.
+\item Hot-keys for easy access to certain often used constructs, e.g.,
+  font changes, accented letters, and mathematical symbols.
+\item Running application programs (such as \TeX), and then parsing
+  the output so that errors in the document may be located 
+  easily.
+\item Support for multi-file documents.
+\item Online help for \AllTeX\ error messages.
+\item Outlining\Dash i.e., manipulating the document as a composition
+  of nested/sequential logical constructs.
+\item Instant formatting and indentation of the \ascii-document in
+  order to make it easier to read.
+\item `Completion' (and thereby spell-checking) of partially written
+  control sequences.

+The master file associated with the current buffer.  If the file being

+the name of the master file by setting this variable.  If there are
+multiple levels of nesting, specify the top level file.@refill
+
+If this variable is @code{nil}, AUC @TeX{} will query you for the
+name.@refill
+
+If the variable is @code{t}, then AUC @TeX{} will assume the file is a master
+file itself.@refill
+
+If the variable is @code{shared}, then AUC @TeX{} will query for the name,

+It is suggested that you use the File Variables (@pxref{File

+Regular expression matching ordinary TeX files.
+
+You should set this variable to match the name of all files, for which
+it is a good idea to append a @code{TeX-master} file variable entry
+automatically.  When AUC @TeX{} adds the name of the master file as a
+file variable, it does not need to ask next time you edit the file.
+
+If you dislike AUC @TeX{} automatically modifying your files, you can
+set this variable to @samp{"<none>"}.  By default, AUC @TeX{} will modify
+any file with an extension of @samp{.tex}.@refill
+@end defopt
+
+AUC @TeX{} keeps track of macros, environments, labels, and style
+files that are used in a given document.  For this to work with
+multifile documents, AUC @TeX{} has to have a place to put the
+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, AUC @TeX{} will write information
+about the file into the @file{auto} directory.  When you load a file,
+AUC @TeX{} 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, AUC @TeX{} 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.
+
+AUC TeX will create the @file{auto} directory automatically if
+@code{TeX-auto-save} is non-nil.  Without it, the files in the document
+will not know anything about each other, except for the name of the
+master file.  @xref{Automatic Local}.

+@cindex Untabify
+
+AUC @TeX{} 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 @file{.emacs} file.
+
+@lisp
+(setq TeX-parse-self t) ; Enable parse on load.
+(setq TeX-auto-save t) ; Enable parse on save.
+@end lisp
+
+The later command will make AUC @TeX{} store the parsed information in
+an @file{auto} subdirectory in the directory each time the @TeX{} files
+are stored, @pxref{Automatic Local}.  If AUC @TeX{} 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.@refill
+
+The variables can also be done 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 AUC TeX saves your buffer, it will by default convert all tabs in
+your buffer into spaces.  To disable this behaviour, insert the
+following in your @file{.emacs} file.
+
+@lisp
+(setq TeX-auto-untabify nil)
+@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 @file{.emacs} file.
+
+@lisp
+;; Only parse \documentstyle information.
+(setq-default TeX-auto-regexp-list 'LaTeX-auto-minimal-regexp-list) 
+;; The documentstyle command is usually near the beginning.
+(setq-default TeX-auto-parse-length 2000)
+@end lisp
+
+This example will speed the parsing up significantly, but AUC @TeX{}
+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
+% TeX-auto-parse-length: 999999

+Since AUC @TeX{} 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 @code{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.

+By default AUC @TeX{} will search for customization files in all the

+path directly.  This is useful if you for example want to add another

+@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"
+ (function
+  (lambda ()
+     (TeX-add-symbols
+     '("arabic" TeX-arg-counter)
+     '("label" TeX-arg-define-label)
+     '("ref" TeX-arg-label)
+     '("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, AUC @TeX{} will chose the one with
+the longest definition (i.e. the one with the most arguments).
+
+Thus, to overwrite
+@example
+        '("tref" 1) ; one argument
+@end example
+you can specify 
+@example
+        '("tref" TeX-arg-label ignore) ; 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.
+
+@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.

+@section Adding Support for Environments
+@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"
+ (function
+  (lambda ()
+    (LaTeX-add-environments
+     '("document" LaTeX-env-document)
+     '("enumerate" LaTeX-env-item)
+     '("itemize" LaTeX-env-item)
+     '("list" LaTeX-env-list)))))
+@end lisp 
+
+@findex LaTeX-env-item
+The only hook that is generally useful is @code{LaTeX-env-item}, which is
+used for environments that contain items.  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 AUC @TeX{} prompt for the arguments
+by giving the prompt strings in the call to
+@code{LaTeX-add-environments}.  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"
+ (function
+  (lambda ()
+    (LaTeX-add-environments
+     '("loop" "From" "To" "Step")))))
+@end lisp
+
+If an environment is defined multiple times, AUC @TeX{} will chose the
+one with the longest definition.  Thus, if you have an enumerate style
+file, and want it to replace the standard La@TeX{} 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"
+ (function
+  (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} ]

+@cindex Parsing new macros
+@cindex @file{macro.tex}

+@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
+
+AUC @TeX{} 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.
+

+
+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 ((REGEXP MATCH TABLE) @dots{}), that

+
+REGEXP.  Regular expression matching the macro we want to parse.
+
+MATCH.  A number or list of numbers, each representing one
+parenthesized subexpression matched by REGEXP.
+
+TABLE.  The symbol table to store the data.  This can be a function, in
+which case the function is called with the argument 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 MATCH is a number, a list of
+strings if MATCH is a list of numbers) is put in front of the table.

+One of the annoying things of latex-help is that if you ask for \LARGE, you
