-
-Using Texinfo, you can create a printed document with the normal
-features of a book, including chapters, sections, cross references,
-and indices. From the same Texinfo source file, you can create a
-menu-driven, on-line Info file with nodes, menus, cross references,
-and indices. You can, if you wish, make the chapters and sections of
-the printed document correspond to the nodes of the on-line
-information; and you use the same cross references and indices for
-both the Info file and the printed work. @cite{The GNU
-Emacs Manual} is a good example of a Texinfo file, as is this manual.@refill
-
-To make a printed document, you process a Texinfo source file with the
-@TeX{} typesetting program. This creates a DVI file that you can
-typeset and print as a book or report. (Note that the Texinfo language
-is completely different from @TeX{}'s usual language, plain @TeX{}.) If
-you do not have @TeX{}, but do have @code{troff} or @code{nroff}, you
-can use the @code{texi2roff} program instead.@refill
-
-To make an Info file, you process a Texinfo source file with the
-@code{makeinfo} utility or Emacs's @code{texinfo-format-buffer} command;
-this creates an Info file that you can install on-line.@refill
-
-@TeX{} and @code{texi2roff} work with many types of printers; similarly,
-Info works with almost every type of computer terminal. This power
-makes Texinfo a general purpose system, but brings with it a constraint,
-which is that a Texinfo file may contain only the customary
-``typewriter'' characters (letters, numbers, spaces, and punctuation
-marks) but no special graphics.@refill
-
-A Texinfo file is a plain @sc{ascii} file containing text and
-@dfn{@@-commands} (words preceded by an @samp{@@}) that tell the
-typesetting and formatting programs what to do. You may edit a
-Texinfo file with any text editor; but it is especially convenient to
-use GNU Emacs since that editor has a special mode, called Texinfo
-mode, that provides various Texinfo-related features. (@xref{Texinfo
-Mode}.)@refill
-
-Before writing a Texinfo source file, you should become familiar with
-the Info documentation reading program and learn about nodes,
-menus, cross references, and the rest. (@inforef{Top, info, info},
-for more information.)@refill
-
-You can use Texinfo to create both on-line help and printed manuals;
-moreover, Texinfo is freely redistributable. For these reasons, Texinfo
-is the format in which documentation for GNU utilities and libraries is
-written.@refill

-An Info file is a Texinfo file formatted so that the Info documentation
-reading program can operate on it. (@code{makeinfo}
-and @code{texinfo-format-buffer} are two commands that convert a Texinfo file
-into an Info file.)@refill
-
-Info files are divided into pieces called @dfn{nodes}, each of which
-contains the discussion of one topic. Each node has a name, and
-contains both text for the user to read and pointers to other nodes,
-which are identified by their names. The Info program displays one node
-at a time, and provides commands with which the user can move to other
-related nodes.@refill
-
-@ifinfo
-@inforef{Top, info, info}, for more information about using Info.@refill
-@end ifinfo
-
-Each node of an Info file may have any number of child nodes that
-describe subtopics of the node's topic. The names of child
-nodes are listed in a @dfn{menu} within the parent node; this
-allows you to use certain Info commands to move to one of the child
-nodes. Generally, an Info file is organized like a book. If a node
-is at the logical level of a chapter, its child nodes are at the level
-of sections; likewise, the child nodes of sections are at the level
-of subsections.@refill
-
-All the children of any one parent are linked together in a
-bidirectional chain of `Next' and `Previous' pointers. The `Next'
-pointer provides a link to the next section, and the `Previous' pointer
-provides a link to the previous section. This means that all the nodes
-that are at the level of sections within a chapter are linked together.
-Normally the order in this chain is the same as the order of the
-children in the parent's menu. Each child node records the parent node
-name as its `Up' pointer. The last child has no `Next' pointer, and the
-first child has the parent both as its `Previous' and as its `Up'
-pointer.@footnote{In some documents, the first child has no `Previous'
-pointer. Occasionally, the last child has the node name of the next
-following higher level node as its `Next' pointer.}@refill
-
-The book-like structuring of an Info file into nodes that correspond
-to chapters, sections, and the like is a matter of convention, not a
-requirement. The `Up', `Previous', and `Next' pointers of a node can
-point to any other nodes, and a menu can contain any other nodes.
-Thus, the node structure can be any directed graph. But it is usually
-more comprehensible to follow a structure that corresponds to the
-structure of chapters and sections in a printed book or report.@refill
-
-In addition to menus and to `Next', `Previous', and `Up' pointers, Info
-provides pointers of another kind, called references, that can be
-sprinkled throughout the text. This is usually the best way to
-represent links that do not fit a hierarchical structure.@refill
-
-Usually, you will design a document so that its nodes match the
-structure of chapters and sections in the printed output. But
-occasionally there are times when this is not right for the material
-being discussed. Therefore, Texinfo uses separate commands to specify
-the node structure for the Info file and the section structure for the
-printed output.@refill
-
-Generally, you enter an Info file through a node that by convention is
-named `Top'. This node normally contains just a brief summary of the
-file's purpose, and a large menu through which the rest of the file is
-reached. From this node, you can either traverse the file
-systematically by going from node to node, or you can go to a specific
-node listed in the main menu, or you can search the index menus and then
-go directly to the node that has the information you want. Alternatively,
-with the standalone Info program, you can specify specific menu items on
-the command line (@pxref{Top,,, info, Info}).
-
-If you want to read through an Info file in sequence, as if it were a
-printed manual, you can hit @key{SPC} repeatedly, or you get the whole
-file with the advanced Info command @kbd{g *}. (@inforef{Expert,
-Advanced Info commands, info}.)@refill

-@cindex Knuth, Donald
-A Texinfo file can be formatted and typeset as a printed book or manual.
-To do this, you need @TeX{}, a powerful, sophisticated typesetting
-program written by Donald Knuth.@footnote{You can also use the
-@code{texi2roff} program if you do not have @TeX{}; since Texinfo is
-designed for use with @TeX{}, @code{texi2roff} is not described here.
-@code{texi2roff} is not part of the standard GNU distribution.}
-
-A Texinfo-based book is similar to any other typeset, printed work: it
-can have a title page, copyright page, table of contents, and preface,
-as well as chapters, numbered or unnumbered sections and subsections,
-page headers, cross references, footnotes, and indices.@refill
-
-You can use Texinfo to write a book without ever having the intention
-of converting it into on-line information. You can use Texinfo for
-writing a printed novel, and even to write a printed memo, although
-this latter application is not recommended since electronic mail is so
-much easier.@refill
-
-@TeX{} is a general purpose typesetting program. Texinfo provides a
-file called @file{texinfo.tex} that contains information (definitions or
-@dfn{macros}) that @TeX{} uses when it typesets a Texinfo file.
-(@file{texinfo.tex} tells @TeX{} how to convert the Texinfo @@-commands
-to @TeX{} commands, which @TeX{} can then process to create the typeset
-document.) @file{texinfo.tex} contains the specifications for printing
-a document.@refill
-
-Most often, documents are printed on 8.5 inch by 11 inch
-pages (216@dmn{mm} by 280@dmn{mm}; this is the default size), but you
-can also print for 7 inch by 9.25 inch pages (178@dmn{mm} by
-235@dmn{mm}; the @code{@@smallbook} size) or on European A4 size paper
-(@code{@@afourpaper}). (@xref{smallbook, , Printing ``Small'' Books}.
-Also, see @ref{A4 Paper, ,Printing on A4 Paper}.)@refill
-
-By changing the parameters in @file{texinfo.tex}, you can change the
-size of the printed document. In addition, you can change the style in
-which the printed document is formatted; for example, you can change the
-sizes and fonts used, the amount of indentation for each paragraph, the
-degree to which words are hyphenated, and the like. By changing the
-specifications, you can make a book look dignified, old and serious, or
-light-hearted, young and cheery.@refill
-
-@TeX{} is freely distributable. It is written in a superset of Pascal
-called WEB and can be compiled either in Pascal or (by using a
-conversion program that comes with the @TeX{} distribution) in C.
-(@xref{TeX Mode, ,@TeX{} Mode, emacs, The GNU Emacs Manual}, for information
-about @TeX{}.)@refill
-
-@TeX{} is very powerful and has a great many features. Because a
-Texinfo file must be able to present information both on a
-character-only terminal in Info form and in a typeset book, the
-formatting commands that Texinfo supports are necessarily
-limited.@refill

-printed manual and tell @code{makeinfo} and
-@code{texinfo-format-buffer} how to create an Info file are preceded
-by @samp{@@}; they are called @dfn{@@-commands}. For example,
-@code{@@node} is the command to indicate a node and @code{@@chapter}
-is the command to indicate the start of a chapter.@refill
-
-@quotation
-@strong{Please note:} All the @@-commands, with the exception of the
-@code{@@TeX@{@}} command, must be written entirely in lower
-case.@refill
-@end quotation
-
-The Texinfo @@-commands are a strictly limited set of constructs. The
-strict limits make it possible for Texinfo files to be understood both
-by @TeX{} and by the code that converts them into Info files. You can
-display Info files on any terminal that displays alphabetic and
-numeric characters. Similarly, you can print the output generated by
-@TeX{} on a wide variety of printers.@refill
-
-Depending on what they do or what arguments@footnote{The word
-@dfn{argument} comes from the way it is used in mathematics and does
-not refer to a disputation between two people; it refers to the
-information presented to the command. According to the @cite{Oxford
-English Dictionary}, the word derives from the Latin for @dfn{to make
-clear, prove}; thus it came to mean `the evidence offered as proof',
-which is to say, `the information offered', which led to its
-mathematical meaning. In its other thread of derivation, the word
-came to mean `to assert in a manner against which others may make
-counter assertions', which led to the meaning of `argument' as a
-disputation.} they take, you need to write @@-commands on lines of
-their own or as part of sentences:@refill
-
-@itemize @bullet
-@item
-Write a command such as @code{@@noindent} at the beginning of a line as
-the only text on the line. (@code{@@noindent} prevents the beginning of
-the next line from being indented as the beginning of a
-paragraph.)@refill
-
-@item
-Write a command such as @code{@@chapter} at the beginning of a line
-followed by the command's arguments, in this case the chapter title, on
-the rest of the line. (@code{@@chapter} creates chapter titles.)@refill

-@cindex Braces, when to use
-As a general rule, a command requires braces if it mingles among other
-text; but it does not need braces if it starts a line of its own. The
-non-alphabetic commands, such as @code{@@:}, are exceptions to the rule;
-they do not need braces.@refill
-
-As you gain experience with Texinfo, you will rapidly learn how to
-write the different commands: the different ways to write commands

-All printable @sc{ascii} characters except @samp{@@}, @samp{@{} and
-@samp{@}} can appear in a Texinfo file and stand for themselves.
-@samp{@@} is the escape character which introduces commands.
-@samp{@{} and @samp{@}} should be used only to surround arguments to
-certain commands. To put one of these special characters into the
-document, put an @samp{@@} character in front of it, like this:
-@samp{@@@@}, @samp{@@@{}, and @samp{@@@}}.@refill
-
-@ifinfo
-It is customary in @TeX{} to use doubled single-quote characters to
-begin and end quotations: ` ` and ' ' (but without a space between the
-two single-quote characters). This convention should be followed in
-Texinfo files. @TeX{} converts doubled single-quote characters to
-left- and right-hand doubled quotation marks and Info converts doubled
-single-quote characters to @sc{ascii} double-quotes: ` ` and ' ' to " .@refill
-@end ifinfo
-@iftex
-It is customary in @TeX{} to use doubled single-quote characters to
-begin and end quotations: @w{@tt{ `` }} and @w{@tt{ '' }}. This
-convention should be followed in Texinfo files. @TeX{} converts
-doubled single-quote characters to left- and right-hand doubled
-quotation marks, ``like this'', and Info converts doubled single-quote
-characters to @sc{ascii} double-quotes: @w{@tt{ `` }} and
-@w{@tt{ '' }} to @w{@tt{ " }}.@refill
-@end iftex
-
-Use three hyphens in a row, @samp{---}, for a dash---like this. In
-@TeX{}, a single or double hyphen produces a printed dash that is
-shorter than the usual typeset dash. Info reduces three hyphens to two
-for display on the screen.
-
-To prevent a paragraph from being indented in the printed manual, put
-the command @code{@@noindent} on a line by itself before the
-paragraph.@refill
-
-If you mark off a region of the Texinfo file with the @code{@@iftex}
-and @w{@code{@@end iftex}} commands, that region will appear only in
-the printed copy; in that region, you can use certain commands
-borrowed from plain @TeX{} that you cannot use in Info. Likewise, if
-you mark off a region with the @code{@@ifinfo} and @code{@@end ifinfo}
-commands, that region will appear only in the Info file; in that
-region, you can use Info commands that you cannot use in @TeX{}.
-Similarly for @code{@@ifhtml @dots{} @@end ifhtml},
-@code{@@ifnothtml @dots{} @@end ifnothtml},
-@code{@@ifnotinfo @dots{} @@end ifnotinfo},
-@code{@@ifnottex @dots{} @@end ifnottex},

-@cindex Tabs; don't use!
-@quotation
-@strong{Caution:} Do not use tabs in a Texinfo file! @TeX{} uses
-variable-width fonts, which means that it cannot predefine a tab to work
-in all circumstances. Consequently, @TeX{} treats tabs like single
-spaces, and that is not what they look like. Furthermore,
-@code{makeinfo} does nothing special with tabs, and thus a tab character
-in your input file may appear differently in the output.
-
-@noindent
-To avoid this problem, Texinfo mode causes GNU Emacs to insert multiple
-spaces when you press the @key{TAB} key.@refill

-Also, you can run @code{untabify} in Emacs to convert tabs in a region
-to multiple spaces.@refill

-
-You can write comments in a Texinfo file that will not appear in
-either the Info file or the printed manual by using the
-@code{@@comment} command (which may be abbreviated to @code{@@c}).
-Such comments are for the person who reads the Texinfo file. All the
-text on a line that follows either @code{@@comment} or @code{@@c} is a
-comment; the rest of the line does not appear in either the Info file
-or the printed manual. (Often, you can write the @code{@@comment} or
-@code{@@c} in the middle of a line, and only the text that follows after
-the @code{@@comment} or @code{@@c} command does not appear; but some
-commands, such as @code{@@settitle} and @code{@@setfilename}, work on a
-whole line. You cannot use @code{@@comment} or @code{@@c} in a line
-beginning with such a command.)@refill
-@cindex Comments
-@findex comment
-@findex c @r{(comment)}
-
-You can write long stretches of text that will not appear in either
-the Info file or the printed manual by using the @code{@@ignore} and
-@code{@@end ignore} commands. Write each of these commands on a line
-of its own, starting each command at the beginning of the line. Text
-between these two commands does not appear in the processed output.
-You can use @code{@@ignore} and @code{@@end ignore} for writing
-comments. Often, @code{@@ignore} and @code{@@end ignore} is used
-to enclose a part of the copying permissions that applies to the
-Texinfo source file of a document, but not to the Info or printed
-version of the document.@refill
-@cindex Ignored text
-@cindex Unprocessed text
-@findex ignore
-@c !!! Perhaps include this comment about ignore and ifset:
-@ignore
-Text enclosed by @code{@@ignore} or by failing @code{@@ifset} or
-@code{@@ifclear} conditions is ignored in the sense that it will not
-contribute to the formatted output. However, TeX and makeinfo must
-still parse the ignored text, in order to understand when to
-@emph{stop} ignoring text from the source file; that means that you
-will still get error messages if you have invalid Texinfo markup
-within ignored text.

-@cindex Texinfo file minimum
-
-By convention, the names of Texinfo files end with one of the
-extensions @file{.texinfo}, @file{.texi}, or @file{.tex}. The longer
-extension is preferred since it describes more clearly to a human
-reader the nature of the file. The shorter extensions are for
-operating systems that cannot handle long file names.@refill
-
-In order to be made into a printed manual and an Info file, a Texinfo

-
-@example
-@@bye
-@end example
-
-@findex input @r{(@TeX{} command)}
-@noindent
-The @samp{\input texinfo} line tells @TeX{} to use the
-@file{texinfo.tex} file, which tells @TeX{} how to translate the Texinfo
-@@-commands into @TeX{} typesetting commands. (Note the use of the
-backslash, @samp{\}; this is correct for @TeX{}.) The
-@samp{@@setfilename} line provides a name for the Info file and tells
-@TeX{} to open auxiliary files. The @samp{@@settitle} line specifies a
-title for the page headers (or footers) of the printed manual.@refill
-
-The @code{@@bye} line at the end of the file on a line of its own tells
-the formatters that the file is ended and to stop formatting.@refill
-
-Usually, you will not use quite such a spare format, but will include
-mode setting and start-of-header and end-of-header lines at the
-beginning of a Texinfo file, like this:@refill
-
-@example
-@group
-\input texinfo @@c -*-texinfo-*-
-@@c %**start of header
-@@setfilename @var{info-file-name}
-@@settitle @var{name-of-manual}

-In the first line, @samp{-*-texinfo-*-} causes Emacs to switch into
-Texinfo mode when you edit the file.
-
-The @code{@@c} lines which surround the @samp{@@setfilename} and
-@samp{@@settitle} lines are optional, but you need them in order to
-run @TeX{} or Info on just part of the file. (@xref{Start of Header},
-for more information.)@refill
-
-Furthermore, you will usually provide a Texinfo file with a title

-@section The Usual GNU Emacs Editing Commands
-
-In most cases, the usual Text mode commands work the same in Texinfo
-mode as they do in Text mode. Texinfo mode adds new editing commands
-and tools to GNU Emacs' general purpose editing features. The major
-difference concerns filling. In Texinfo mode, the paragraph
-separation variable and syntax table are redefined so that Texinfo
-commands that should be on lines of their own are not inadvertently
-included in paragraphs. Thus, the @kbd{M-q} (@code{fill-paragraph})
-command will refill a paragraph but not mix an indexing command on a
-line adjacent to it into the paragraph.@refill
-
-In addition, Texinfo mode sets the @code{page-delimiter} variable to
-the value of @code{texinfo-chapter-level-regexp}; by default, this is
-a regular expression matching the commands for chapters and their
-equivalents, such as appendices. With this value for the page
-delimiter, you can jump from chapter title to chapter title with the
-@kbd{C-x ]} (@code{forward-page}) and @kbd{C-x [}
-(@code{backward-page}) commands and narrow to a chapter with the
-@kbd{C-x p} (@code{narrow-to-page}) command. (@xref{Pages, , ,emacs,
-The GNU Emacs Manual}, for details about the page commands.)@refill
-
-You may name a Texinfo file however you wish, but the convention is to
-end a Texinfo file name with one of the three extensions
-@file{.texinfo}, @file{.texi}, or @file{.tex}. A longer extension is
-preferred, since it is explicit, but a shorter extension may be
-necessary for operating systems that limit the length of file names.
-GNU Emacs automatically enters Texinfo mode when you visit a file with
-a @file{.texinfo} or @file{.texi}
-extension. Also, Emacs switches to Texinfo mode
-when you visit a
-file that has @samp{-*-texinfo-*-} in its first line. If ever you are
-in another mode and wish to switch to Texinfo mode, type @code{M-x
-texinfo-mode}.@refill
-
-Like all other Emacs features, you can customize or enhance Texinfo
-mode as you wish. In particular, the keybindings are very easy to
-change. The keybindings described here are the default or standard
-ones.@refill

-@kbd{C-c C-c C-d} (@code{texinfo-start-menu-description}) is an insert
-command that works differently from the other insert commands. It
-inserts a node's section or chapter title in the space for the
-description in a menu entry line. (A menu entry has three parts, the
-entry name, the node name, and the description. Only the node name is
-required, but a description helps explain what the node is about.

-description; it positions point at beginning of the inserted text so you
-can edit it. The function does not insert the title if the menu entry
-line already contains a description.@refill
-
-This command is only an aid to writing descriptions; it does not do the
-whole job. You must edit the inserted text since a title tends to use
-the same words as a node name but a useful description uses different
-words.@refill

-Texinfo mode provides commands for automatically creating or updating

-
-You can use the updating commands@refill
-
-@itemize @bullet
-@item
-to insert or update the `Next', `Previous', and `Up' pointers of a
-node,@refill
-
-@item
-to insert or update the menu for a section, and@refill
-
-@item
-to create a master menu for a Texinfo source file.@refill
-@end itemize
-
-You can also use the commands to update all the nodes and menus in a
-region or in a whole Texinfo file.@refill
-
-The updating commands work only with conventional Texinfo files, which
-are structured hierarchically like books. In such files, a structuring
-command line must follow closely after each @code{@@node} line, except
-for the `Top' @code{@@node} line. (A @dfn{structuring command line} is
-a line beginning with @code{@@chapter}, @code{@@section}, or other
-similar command.)
-
-You can write the structuring command line on the line that follows
-immediately after an @code{@@node} line or else on the line that
-follows after a single @code{@@comment} line or a single
-@code{@@ifinfo} line. You cannot interpose more than one line between
-the @code{@@node} line and the structuring command line; and you may
-interpose only an @code{@@comment} line or an @code{@@ifinfo} line.
-
-Commands which work on a whole buffer require that the `Top' node be
-followed by a node with an @code{@@chapter} or equivalent-level command.
-Note that the menu updating commands will not create a main or master
-menu for a Texinfo file that has only @code{@@chapter}-level nodes! The
-menu updating commands only create menus @emph{within} nodes for lower level
-nodes. To create a menu of chapters, you must provide a `Top'
-node.@refill
-
-The menu updating commands remove menu entries that refer to other Info
-files since they do not refer to nodes within the current buffer. This
-is a deficiency. Rather than use menu entries, you can use cross
-references to refer to other Info files. None of the updating commands
-affect cross references.@refill
-
-Texinfo mode has five updating commands that are used most often: two
-are for updating the node pointers or menu of a single node (or a
-region); two are for updating every node pointer and menu in a file;
-and one, the @code{texinfo-master-menu} command, is for creating a
-master menu for a complete file, and optionally, for updating every
-node and menu in the whole Texinfo file.@refill
-
-The @code{texinfo-master-menu} command is the primary command:@refill
-
-@table @kbd
-@item C-c C-u m
-@itemx M-x texinfo-master-menu
-@findex texinfo-master-menu
-Create or update a master menu that includes all the other menus
-(incorporating the descriptions from pre-existing menus, if
-any).@refill
-
-With an argument (prefix argument, @kbd{C-u,} if interactive), first create or
-update all the nodes and all the regular menus in the buffer before
-constructing the master menu. (@xref{The Top Node, , The Top Node and
-Master Menu}, for more about a master menu.)@refill
-
-For @code{texinfo-master-menu} to work, the Texinfo file must have a
-`Top' node and at least one subsequent node.@refill
-
-After extensively editing a Texinfo file, you can type the following:
-
-@example
-C-u M-x texinfo-master-menu
-@exdent or
-C-u C-c C-u m
-@end example
-
-@noindent
-This updates all the nodes and menus completely and all at once.@refill
-@end table
-
-The other major updating commands do smaller jobs and are designed for
-the person who updates nodes and menus as he or she writes a Texinfo
-file.@refill
-
-@need 1000
-The commands are:@refill
-
-@table @kbd
-@item C-c C-u C-n
-@itemx M-x texinfo-update-node
-@findex texinfo-update-node
-Insert the `Next', `Previous', and `Up' pointers for the node that point is
-within (i.e., for the @code{@@node} line preceding point). If the
-@code{@@node} line has pre-existing `Next', `Previous', or `Up'
-pointers in it, the old pointers are removed and new ones inserted.
-With an argument (prefix argument, @kbd{C-u}, if interactive), this command
-updates all @code{@@node} lines in the region (which is the text
-between point and mark).@refill
-
-@item C-c C-u C-m
-@itemx M-x texinfo-make-menu
-@findex texinfo-make-menu
-Create or update the menu in the node that point is within.
-With an argument (@kbd{C-u} as prefix argument, if
-interactive), the command makes or updates menus for the
-nodes which are either within or a part of the
-region.@refill
-
-Whenever @code{texinfo-make-menu} updates an existing menu, the
-descriptions from that menu are incorporated into the new menu. This
-is done by copying descriptions from the existing menu to the entries
-in the new menu that have the same node names. If the node names are
-different, the descriptions are not copied to the new menu.@refill
-
-@item C-c C-u C-e
-@itemx M-x texinfo-every-node-update
-@findex texinfo-every-node-update
-Insert or update the `Next', `Previous', and `Up' pointers for every
-node in the buffer.@refill
-
-@item C-c C-u C-a
-@itemx M-x texinfo-all-menus-update
-@findex texinfo-all-menus-update
-Create or update all the menus in the buffer. With an argument
-(@kbd{C-u} as prefix argument, if interactive), first insert
-or update all the node
-pointers before working on the menus.@refill
-
-If a master menu exists, the @code{texinfo-all-menus-update} command
-updates it; but the command does not create a new master menu if none
-already exists. (Use the @code{texinfo-master-menu} command for
-that.)@refill
-
-When working on a document that does not merit a master menu, you can
-type the following:
-
-@example
-C-u C-c C-u C-a
-@exdent or
-C-u M-x texinfo-all-menus-update
-@end example
-
-@noindent
-This updates all the nodes and menus.@refill
-@end table
-
-The @code{texinfo-column-for-description} variable specifies the
-column to which menu descriptions are indented. By default, the value
-is 32 although it is often useful to reduce it to as low as 24. You
-can set the variable with the @kbd{M-x edit-options} command
-(@pxref{Edit Options, , Editing Variable Values, emacs, The GNU Emacs

-
-Also, the @code{texinfo-indent-menu-description} command may be used to
-indent existing menu descriptions to a specified column. Finally, if
-you wish, you can use the @code{texinfo-insert-node-lines} command to
-insert missing @code{@@node} lines into a file. (@xref{Other Updating

-@comment node-name, next, previous, up
-@subsection Updating Requirements
-@cindex Updating requirements
-@cindex Requirements for updating commands
-
-To use the updating commands, you must organize the Texinfo file
-hierarchically with chapters, sections, subsections, and the like.
-When you construct the hierarchy of the manual, do not `jump down'
-more than one level at a time: you can follow the `Top' node with a
-chapter, but not with a section; you can follow a chapter with a
-section, but not with a subsection. However, you may `jump up' any
-number of levels at one time---for example, from a subsection to a
-chapter.@refill
-
-Each @code{@@node} line, with the exception of the line for the `Top'
-node, must be followed by a line with a structuring command such as
-@code{@@chapter}, @code{@@section}, or
-@code{@@unnumberedsubsec}.@refill
-
-Each @code{@@node} line/structuring-command line combination
-must look either like this:@refill
-
-@example
-@group
-@@node Comments, Minimum, Conventions, Overview
-@@comment node-name, next, previous, up
-@@section Comments
-@end group
-@end example
-
-or like this (without the @code{@@comment} line):
-
-@example
-@group
-@@node Comments, Minimum, Conventions, Overview
-@@section Comments
-@end group
-@end example
-
-@noindent
-In this example, `Comments' is the name of both the node and the
-section. The next node is called `Minimum' and the previous node is
-called `Conventions'. The `Comments' section is within the `Overview'
-node, which is specified by the `Up' pointer. (Instead of an
-@code{@@comment} line, you can write an @code{@@ifinfo} line.)@refill
-
-If a file has a `Top' node, it must be called @samp{top} or @samp{Top}
-and be the first node in the file.@refill
-
-The menu updating commands create a menu of sections within a chapter,
-a menu of subsections within a section, and so on. This means that
-you must have a `Top' node if you want a menu of chapters.@refill
-
-Incidentally, the @code{makeinfo} command will create an Info file for
-a hierarchically organized Texinfo file that lacks `Next', `Previous'
-and `Up' pointers. Thus, if you can be sure that your Texinfo file
-will be formatted with @code{makeinfo}, you have no need for the
-`update node' commands. (@xref{Create an Info File, , Creating an
-Info File}, for more information about @code{makeinfo}.) However,
-both @code{makeinfo} and the @code{texinfo-format-@dots{}} commands
-require that you insert menus in the file.@refill

-@subsection Other Updating Commands
-
-In addition to the five major updating commands, Texinfo mode
-possesses several less frequently used updating commands:@refill
-
-@table @kbd
-@item M-x texinfo-insert-node-lines
-@findex texinfo-insert-node-lines
-Insert @code{@@node} lines before the @code{@@chapter},
-@code{@@section}, and other sectioning commands wherever they are
-missing throughout a region in a Texinfo file.@refill
-
-With an argument (@kbd{C-u} as prefix argument, if interactive), the
-@code{texinfo-insert-node-lines} command not only inserts
-@code{@@node} lines but also inserts the chapter or section titles as
-the names of the corresponding nodes. In addition, it inserts the
-titles as node names in pre-existing @code{@@node} lines that lack
-names. Since node names should be more concise than section or
-chapter titles, you must manually edit node names so inserted.@refill
-
-For example, the following marks a whole buffer as a region and inserts
-@code{@@node} lines and titles throughout:@refill
-
-@example
-C-x h C-u M-x texinfo-insert-node-lines
-@end example
-
-(Note that this command inserts titles as node names in @code{@@node}
-lines; the @code{texinfo-start-menu-description} command
-(@pxref{Inserting, Inserting Frequently Used Commands}) inserts titles
-as descriptions in menu entries, a different action. However, in both
-cases, you need to edit the inserted text.)@refill
-
-@item M-x texinfo-multiple-files-update
-@findex texinfo-multiple-files-update @r{(in brief)}
-Update nodes and menus in a document built from several separate files.
-With @kbd{C-u} as a prefix argument, create and insert a master menu in
-the outer file. With a numeric prefix argument, such as @kbd{C-u 2}, first
-update all the menus and all the `Next', `Previous', and `Up' pointers
-of all the included files before creating and inserting a master menu in
-the outer file. The @code{texinfo-multiple-files-update} command is

-descriptions. With an argument (@kbd{C-u} as prefix argument, if
-interactive), the @code{texinfo-indent-menu-description} command indents
-every description in every menu in the region. However, this command
-does not indent the second and subsequent lines of a multi-line
-description.@refill
-
-@item M-x texinfo-sequential-node-update
-@findex texinfo-sequential-node-update
-Insert the names of the nodes immediately following and preceding the
-current node as the `Next' or `Previous' pointers regardless of those
-nodes' hierarchical level. This means that the `Next' node of a
-subsection may well be the next chapter. Sequentially ordered nodes are
-useful for novels and other documents that you read through
-sequentially. (However, in Info, the @kbd{g *} command lets
-you look through the file sequentially, so sequentially ordered nodes

-The insert commands are invoked by typing @kbd{C-c} twice and then the
-first letter of the @@-command to be inserted. (It might make more
-sense mnemonically to use @kbd{C-c C-i}, for `custom insert', but
-@kbd{C-c C-c} is quick to type.)@refill
-
-@example
-C-c C-c c @r{Insert} @samp{@@code}.
-C-c C-c d @r{Insert} @samp{@@dfn}.
-C-c C-c e @r{Insert} @samp{@@end}.
-C-c C-c i @r{Insert} @samp{@@item}.
-C-c C-c n @r{Insert} @samp{@@node}.
-C-c C-c s @r{Insert} @samp{@@samp}.

-Texinfo files start with at least three lines that provide Info and

-This line serves two functions:

-@samp{\}, to mark the beginning of a command, just as Texinfo uses
-@samp{@@}. The @file{texinfo.tex} file causes the switch from @samp{\}

-end-of-header line (@pxref{End of Header}).@refill
-
-With these lines, you can format part of a Texinfo file for Info or
-typeset part for printing.@refill
-
-A start-of-header line looks like this:@refill
-
-@example
-@@c %**start of header
-@end example
-
-The odd string of characters, @samp{%**}, is to ensure that no other

-@findex setfilename
-
-In order to serve as the primary input file for either @code{makeinfo}
-or @TeX{}, a Texinfo file must contain a line that looks like this:
-
-@example
-@@setfilename @var{info-file-name}
-@end example
-
-Write the @code{@@setfilename} command at the beginning of a line and
-follow it on the same line by the Info file name. Do not write anything
-else on the line; anything on the line after the command is considered
-part of the file name, including what would otherwise be a
-comment.
-
-The @code{@@setfilename} line specifies the name of the Info file to be
-generated. This name should be different from the name of the Texinfo
-file. There are two conventions for choosing the name: you can either
-remove the @samp{.texi} extension from the input file name, or replace
-it with the @samp{.info} extension.
-
-Some operating systems cannot handle long file names. You can run into
-a problem even when the file name you specify is itself short enough.
-This occurs because the Info formatters split a long Info file into
-short indirect subfiles, and name them by appending @samp{-1},
-@samp{-2}, @dots{}, @samp{-10}, @samp{-11}, and so on, to the original
-file name. (@xref{Tag and Split Files, , Tag Files and Split Files}.)
-The subfile name @file{texinfo.info-10}, for example, is too long for
-some systems; so the Info file name for this document is @file{texinfo}
-rather than @file{texinfo.info}.
-
-@cindex Ignored before @code{@@setfilename}
-The Info formatting commands ignore everything written before the
-@code{@@setfilename} line, which is why the very first line of
-the file (the @code{\input} line) does not show up in the output.
-
-@pindex texinfo.cnf
-The @code{@@setfilename} line produces no output when you typeset a
-manual with @TeX{}, but it nevertheless is essential: it opens the
-index, cross-reference, and other auxiliary files used by Texinfo, and
-also reads @file{texinfo.cnf} if that file is present on your system
-(@pxref{Preparing for TeX,, Preparing to Use @TeX{}}).

-
-@example
-@@settitle @var{title}
-@end example
-
-Write the @code{@@settitle} command at the beginning of a line and

-to use in a header or footer. Do not write anything else on the line;
-anything on the line after the command is considered part of the
-title, including a comment.@refill
-
-Conventionally, when @TeX{} formats a Texinfo file for double-sided
-output, the title is printed in the left-hand (even-numbered) page
-headings and the current chapter title is printed in the right-hand
-(odd-numbered) page headings. (@TeX{} learns the title of each chapter
-from each @code{@@chapter} command.) Page footers are not
-printed.@refill
-
-Even if you are printing in a single-sided style, @TeX{} looks for an
-@code{@@settitle} command line, in case you include the manual title
-in the heading. @refill
-
-The @code{@@settitle} command should precede everything that generates
-actual output in @TeX{}.@refill
-
-Although the title in the @code{@@settitle} command is usually the
-same as the title on the title page, it does not affect the title as
-it appears on the title page. Thus, the two do not need not match

-page. (@xref{titlepage, , @code{@@titlepage}}.)@refill

-In a book or a manual, text is usually printed on both sides of the
-paper, chapters start on right-hand pages, and right-hand pages have
-odd numbers. But in short reports, text often is printed only on one
-side of the paper. Also in short reports, chapters sometimes do not
-start on new pages, but are printed on the same page as the end of the
-preceding chapter, after a small amount of vertical whitespace.@refill
-
-You can use the @code{@@setchapternewpage} command with various
-arguments to specify how @TeX{} should start chapters and whether it
-should typeset pages for printing on one or both sides of the paper
-(single-sided or double-sided printing).@refill
-
-Write the @code{@@setchapternewpage} command at the beginning of a

-@table @asis

-@item No @code{@@setchapternewpage} command
-If the Texinfo file does not contain an @code{@@setchapternewpage}

-begins chapters on new pages and prints headings in the standard
-format for single-sided printing. This is the conventional format for
-single-sided printing.@refill
-
-The result is exactly the same as when you write
-@code{@@setchapternewpage on}.@refill
-@end ignore
-@item @code{@@setchapternewpage off}
-Cause @TeX{} to typeset a new chapter on the same page as the last
-chapter, after skipping some vertical whitespace. Also, cause @TeX{} to
-format page headers for single-sided printing. (You can override the
-headers format with the @code{@@headings double} command; see
-@ref{headings on off, , The @code{@@headings} Command}.)@refill
-
-@item @code{@@setchapternewpage on}
-Cause @TeX{} to start new chapters on new pages and to typeset page
-headers for single-sided printing. This is the form most often
-used for short reports.@refill
-
-This alternative is the default.@refill
-
-@item @code{@@setchapternewpage odd}
-Cause @TeX{} to start new chapters on new, odd-numbered pages
-(right-handed pages) and to typeset for double-sided printing. This is
-the form most often used for books and manuals.@refill
-@end table
-
-@noindent
-Texinfo does not have an @code{@@setchapternewpage even} command.@refill

-
-Since an Info file does not have pages, the @code{@@setchapternewpage}

-Usually, you do not write an @code{@@setchapternewpage} command for

-A manual's name and author are usually printed on a title page.
-Sometimes copyright information is printed on the title page as well;
-more often, copyright information is printed on the back of the title
-page.
-
-The title and copyright pages appear in the printed manual, but not in the
-Info file. Because of this, it is possible to use several slightly
-obscure @TeX{} typesetting commands that cannot be used in an Info file.
-In addition, this part of the beginning of a Texinfo file contains the text
-of the copying permissions that will appear in the printed manual.@refill
-
-@xref{Titlepage Permissions, , Titlepage Copying Permissions}, for the
-standard text for the copyright permissions.@refill

-
-The @code{@@end titlepage} command starts a new page and turns on page
-numbering. (@xref{Headings, , Page Headings}, for details about how to
-generate page headings.) All the material that you want to
-appear on unnumbered pages should be put between the
-@code{@@titlepage} and @code{@@end titlepage} commands. By using the
-@code{@@page} command you can force a page break within the region
-delineated by the @code{@@titlepage} and @code{@@end titlepage}
-commands and thereby create more than one unnumbered page. This is
-how the copyright page is produced. (The @code{@@titlepage} command
-might perhaps have been better named the
-@code{@@titleandadditionalpages} command, but that would have been
-rather long!)@refill
-
-@c !!! append refill to footnote when makeinfo can handle it.
-When you write a manual about a computer program, you should write the
-version of the program to which the manual applies on the title
-page. If the manual changes more frequently than the program or is
-independent of it, you should also include an edition
-number@footnote{We have found that it is helpful to refer to versions
-of manuals as `editions' and versions of programs as `versions';
-otherwise, we find we are liable to confuse each other in conversation
-by referring to both the documentation and the software with the same
-words.} for the manual. This helps readers keep track of which manual
-is for which version of the program. (The `Top' node
-should also contain this information; see @ref{makeinfo top, ,
-@code{@@top}}.)@refill
-
-Texinfo provides two main methods for creating a title page. One method
-uses the @code{@@titlefont}, @code{@@sp}, and @code{@@center} commands
-to generate a title page in which the words on the page are
-centered.@refill
-
-The second method uses the @code{@@title}, @code{@@subtitle}, and
-@code{@@author} commands to create a title page with black rules under
-the title and author lines and the subtitle text set flush to the
-right hand side of the page. With this method, you do not specify any
-of the actual formatting of the title page. You specify the text
-you want, and Texinfo does the formatting. You may use either
-method.@refill
-
-@findex shorttitlepage
-For extremely simple applications, Texinfo also provides a command
-@code{@@shorttitlepage} which takes a single argument as the title.
-The argument is typeset on a page by itself and followed by a blank
-page.

-
-The @code{@@title} command produces a line in which the title is set
-flush to the left-hand side of the page in a larger than normal font.
-The title is underlined with a black rule.@refill
-
-The @code{@@subtitle} command sets subtitles in a normal-sized font

-
-The @code{@@author} command sets the names of the author or authors in
-a middle-sized font flush to the left-hand side of the page on a line

-
-By international treaty, the copyright notice for a book should be
-either on the title page or on the back of the title page. The
-copyright notice should include the year followed by the name of the
-organization or person who owns the copyright.@refill
-
-When the copyright notice is on the back of the title page, that page
-is customarily not numbered. Therefore, in Texinfo, the information
-on the copyright page should be within @code{@@titlepage} and
-@code{@@end titlepage} commands.@refill
-
-@findex vskip
-@findex filll
-@cindex Vertical whitespace (@samp{vskip})
-Use the @code{@@page} command to cause a page break. To push the
-copyright notice and the other text on the copyright page towards the
-bottom of the page, you can write a somewhat mysterious line after the
-@code{@@page} command that reads like this:@refill
-
-@example
-@@vskip 0pt plus 1filll
-@end example
-
-@noindent
-This is a @TeX{} command that is not supported by the Info formatting
-commands. The @code{@@vskip} command inserts whitespace. The
-@samp{0pt plus 1filll} means to put in zero points of mandatory whitespace,
-and as much optional whitespace as needed to push the
-following text to the bottom of the page. Note the use of three
-@samp{l}s in the word @samp{filll}; this is the correct usage in
-@TeX{}.@refill
-
-@findex copyright
-In a printed manual, the @code{@@copyright@{@}} command generates a
-@samp{c} inside a circle. (In Info, it generates @samp{(C)}.) The
-copyright notice itself has the following legally defined sequence:@refill
-
-@example
-Copyright @copyright{} @var{year} @var{copyright-owner}
-@end example
-
-It is customary to put information on how to get a manual after the
-copyright notice, followed by the copying permissions for the
-manual.@refill
-
-Note that permissions must be given here as well as in the summary
-segment within @code{@@ifinfo} and @code{@@end ifinfo} that

-@cindex End titlepage starts headings
-
-An @code{@@end titlepage} command on a line by itself not only marks
-the end of the title and copyright pages, but also causes @TeX{} to start
-generating page headings and page numbers.
-
-To repeat what is said elsewhere, Texinfo has two standard page heading
-formats, one for documents which are printed on one side of each sheet of paper
-(single-sided printing), and the other for documents which are printed on both
-sides of each sheet (double-sided printing).
-(@xref{setchapternewpage, ,@code{@@setchapternewpage}}.)
-You can specify these formats in different ways:@refill
-
-@itemize @bullet
-@item
-The conventional way is to write an @code{@@setchapternewpage} command
-before the title page commands, and then have the @code{@@end
-titlepage} command start generating page headings in the manner desired.
-(@xref{setchapternewpage, , @code{@@setchapternewpage}}.)@refill
-
-@item
-Alternatively, you can use the @code{@@headings} command to prevent page
-headings from being generated or to start them for either single or
-double-sided printing. (Write an @code{@@headings} command immediately
-after the @code{@@end titlepage} command. @xref{headings on off, , The
-@code{@@headings} Command}, for more information.)@refill
-
-@item
-Or, you may specify your own page heading and footing format.
-@xref{Headings, , Page Headings}, for detailed
-information about page headings and footings.@refill
-@end itemize
-
-Most documents are formatted with the standard single-sided or
-double-sided format, using @code{@@setchapternewpage odd} for
-double-sided printing and no @code{@@setchapternewpage} command for
-single-sided printing.@refill
-
-@node headings on off, , end titlepage, Titlepage & Copyright Page
-@comment node-name, next, previous, up
-@subsection The @code{@@headings} Command
-@findex headings
-
-The @code{@@headings} command is rarely used. It specifies what kind of
-page headings and footings to print on each page. Usually, this is
-controlled by the @code{@@setchapternewpage} command. You need the
-@code{@@headings} command only if the @code{@@setchapternewpage} command
-does not do what you want, or if you want to turn off pre-defined page
-headings prior to defining your own. Write an @code{@@headings} command
-immediately after the @code{@@end titlepage} command.@refill
-
-You can use @code{@@headings} as follows:@refill
-
-@table @code
-@item @@headings off
-Turn off printing of page headings.@refill
-
-@item @@headings single
-Turn on page headings appropriate for single-sided printing.
-@refill
-
-@item @@headings double
-Turn on page headings appropriate for double-sided printing. The two
-commands, @code{@@headings on} and @code{@@headings double}, are
-synonymous.@refill
-
-@item @@headings singleafter
-@itemx @@headings doubleafter
-Turn on @code{single} or @code{double} headings, respectively, after the
-current page is output.
-
-@item @@headings on
-Turn on page headings: @code{single} if @samp{@@setchapternewpage
-on}, @code{double} otherwise.
-@end table
-
-For example, suppose you write @code{@@setchapternewpage off} before the
-@code{@@titlepage} command to tell @TeX{} to start a new chapter on the
-same page as the end of the last chapter. This command also causes
-@TeX{} to typeset page headers for single-sided printing. To cause
-@TeX{} to typeset for double sided printing, write @code{@@headings
-double} after the @code{@@end titlepage} command.
-
-You can stop @TeX{} from generating any page headings at all by
-writing @code{@@headings off} on a line of its own immediately after the
-line containing the @code{@@end titlepage} command, like this:@refill
-
-@example
-@@end titlepage
-@@headings off
-@end example
-
-@noindent
-The @code{@@headings off} command overrides the @code{@@end titlepage}
-command, which would otherwise cause @TeX{} to print page
-headings.@refill

-To print an index means to include it as part of a manual or Info
-file. This does not happen automatically just because you use
-@code{@@cindex} or other index-entry generating commands in the
-Texinfo file; those just cause the raw data for the index to be
-accumulated. To generate an index, you must include the
-@code{@@printindex} command at the place in the document where you
-want the index to appear. Also, as part of the process of creating a
-printed manual, you must run a program called @code{texindex}
-(@pxref{Format/Print Hardcopy}) to sort the raw data to produce a sorted
-index file. The sorted index file is what is actually used to
-print the index.@refill
-
-Texinfo offers six different types of predefined index: the concept
-index, the function index, the variables index, the keystroke index, the
-program index, and the data type index (@pxref{Predefined Indices}). Each
-index type has a two-letter name: @samp{cp}, @samp{fn}, @samp{vr},
-@samp{ky}, @samp{pg}, and @samp{tp}. You may merge indices, or put them
-into separate sections (@pxref{Combining Indices}); or you may define
-your own indices (@pxref{New Indices, , Defining New Indices}).@refill
-
-The @code{@@printindex} command takes a two-letter index name, reads
-the corresponding sorted index file and formats it appropriately into
-an index.@refill
-
-@ignore
-The two-letter index names are:
-
-@table @samp
-@item cp
-concept index
-@item fn
-function index
-@item vr
-variable index
-@item ky
-key index
-@item pg
-program index
-@item tp
-data type index
-@end table
-@end ignore
-The @code{@@printindex} command does not generate a chapter heading
-for the index. Consequently, you should precede the
-@code{@@printindex} command with a suitable section or chapter command
-(usually @code{@@unnumbered}) to supply the chapter heading and put
-the index into the table of contents. Precede the @code{@@unnumbered}
-command with an @code{@@node} line.@refill

-A @dfn{node} is a segment of text that begins at an @code{@@node}
-command and continues until the next @code{@@node} command. The
-definition of node is different from that for chapter or section. A
-chapter may contain sections and a section may contain subsections;
-but a node cannot contain subnodes; the text of a node continues only
-until the next @code{@@node} command in the file. A node usually
-contains only one chapter structuring command, the one that follows
-the @code{@@node} line. On the other hand, in printed output nodes
-are used only for cross references, so a chapter or section may
-contain any number of nodes. Indeed, a chapter usually contains
-several nodes, one for each section, subsection, and
-subsubsection.@refill
-
-To create a node, write an @code{@@node} command at the beginning of a
-line, and follow it with four arguments, separated by commas, on the
-rest of the same line. These arguments are the name of the node, and
-the names of the `Next', `Previous', and `Up' pointers, in that order.
-You may insert spaces before each pointer if you wish; the spaces are
-ignored. You must write the name of the node, and the names of the
-`Next', `Previous', and `Up' pointers, all on the same line. Otherwise,
-the formatters fail. (@inforef{Top, info, info}, for more information
-about nodes in Info.)@refill
-
-Usually, you write one of the chapter-structuring command lines
-immediately after an @code{@@node} line---for example, an
-@code{@@section} or @code{@@subsection} line. (@xref{Structuring

-The name of a node identifies the node. The pointers enable

-
-Normally, a node's `Up' pointer contains the name of the node whose menu
-mentions that node. The node's `Next' pointer contains the name of the
-node that follows that node in that menu and its `Previous' pointer
-contains the name of the node that precedes it in that menu. When a

-@cindex Writing an @code{@@node} line
-@cindex @code{@@node} line writing
-@cindex Node line writing
-
-The easiest way to write an @code{@@node} line is to write @code{@@node}
-at the beginning of a line and then the name of the node, like
-this:@refill
-
-@example
-@@node @var{node-name}
-@end example
-
-If you are using GNU Emacs, you can use the update node commands
-provided by Texinfo mode to insert the names of the pointers; or you
-can leave the pointers out of the Texinfo file and let @code{makeinfo}
-insert node pointers into the Info file it creates. (@xref{Texinfo
-Mode}, and @ref{makeinfo Pointer Creation}.)@refill
-
-Alternatively, you can insert the `Next', `Previous', and `Up'
-pointers yourself. If you do this, you may find it helpful to use the
-Texinfo mode keyboard command @kbd{C-c C-c n}. This command inserts
-@samp{@@node} and a comment line listing the names of the pointers in
-their proper order. The comment line helps you keep track of which
-arguments are for which pointers. This comment line is especially useful
-if you are not familiar with Texinfo.@refill
-
-The template for a node line with `Next', `Previous', and `Up' pointers
-looks like this:@refill
-
-@example
-@@node @var{node-name}, @var{next}, @var{previous}, @var{up}
-@end example
-
-If you wish, you can ignore @code{@@node} lines altogether in your first
-draft and then use the @code{texinfo-insert-node-lines} command to
-create @code{@@node} lines for you. However, we do not
-recommend this practice. It is better to name the node itself
-at the same time that you
-write a segment so you can easily make cross references. A large number
-of cross references are an especially important feature of a good Info
-file.@refill
-
-After you have inserted an @code{@@node} line, you should immediately
-write an @@-command for the chapter or section and insert its name.
-Next (and this is important!), put in several index entries. Usually,
-you will find at least two and often as many as four or five ways of
-referring to the node in the index. Use them all. This will make it
-much easier for people to find the node.@refill

-@cindex Unique nodename requirement
-@cindex Nodename must be unique
-@item
-All the node names for a single Info file must be unique.@refill
-
-Duplicates confuse the Info movement commands. This means, for
-example, that if you end every chapter with a summary, you must name
-each summary node differently. You cannot just call each one
-``Summary''. You may, however, duplicate the titles of chapters, sections,
-and the like. Thus you can end each chapter in a book with a section
-called ``Summary'', so long as the node names for those sections are all
-different.@refill

-@subsection The First Node
-@cindex Top node is first
-@cindex First node
-
-The first node of a Texinfo file is the @dfn{Top} node, except in an
-included file (@pxref{Include Files}). The Top node contains the main
-or master menu for the document, and a short summary of the document
-(@pxref{Top Node Summary}).
-
-@cindex Up node of Top node
-@cindex (dir) as Up node of Top node
-The Top node (which must be named @samp{top} or @samp{Top}) should have
-as its `Up' node the name of a node in another file, where there is a
-menu that leads to this file. Specify the file name in parentheses. If
-the file is to be installed directly in the Info directory file, use
-@samp{(dir)} as the parent of the Top node; this is short for
-@samp{(dir)top}, and specifies the Top node in the @file{dir} file,
-which contains the main menu for the Info system as a whole. For
-example, the @code{@@node Top} line of this manual looks like this:
-
-@example
-@@node Top, Copying, , (dir)
-@end example
-
-@noindent
-(You can use the Texinfo updating commands or the @code{makeinfo}
-utility to insert these pointers automatically.)
-
-@cindex Previous node of Top node
-Do not define the `Previous' node of the Top node to be @samp{(dir)}, as
-it causes confusing behavior for users: if you are in the Top node and
-hits @key{DEL} to go backwards, you wind up in the middle of the
-some other entry in the @file{dir} file, which has nothing to do with
-what you were reading.

-@findex top @r{(@@-command)}
-
-A special sectioning command, @code{@@top}, has been created for use
-with the @code{@@node Top} line. The @code{@@top} sectioning command tells
-@code{makeinfo} that it marks the `Top' node in the file. It provides
-the information that @code{makeinfo} needs to insert node
-pointers automatically. Write the @code{@@top} command at the
-beginning of the line immediately following the @code{@@node Top}
-line. Write the title on the remaining part of the same line as the
-@code{@@top} command.@refill
-
-In Info, the @code{@@top} sectioning command causes the title to appear on a
-line by itself, with a line of asterisks inserted underneath.@refill
-
-In @TeX{} and @code{texinfo-format-buffer}, the @code{@@top}
-sectioning command is merely a synonym for @code{@@unnumbered}.
-Neither of these formatters require an @code{@@top} command, and do
-nothing special with it. You can use @code{@@chapter} or
-@code{@@unnumbered} after the @code{@@node Top} line when you use
-these formatters. Also, you can use @code{@@chapter} or
-@code{@@unnumbered} when you use the Texinfo updating commands to
-create or update pointers and menus.@refill

-@node Top Node Summary, , makeinfo top command, node
-@subsection The `Top' Node Summary
-@cindex @samp{@r{Top}} node summary
-
-You can help readers by writing a summary in the `Top' node, after the
-@code{@@top} line, before the main or master menu. The summary should
-briefly describe the document. In Info, this summary will appear just
-before the master menu. In a printed manual, this summary will appear
-on a page of its own.@refill
-
-If you do not want the summary to appear on a page of its own in a
-printed manual, you can enclose the whole of the `Top' node, including
-the @code{@@node Top} line and the @code{@@top} sectioning command line
-or other sectioning command line between @code{@@ifinfo} and @code{@@end
-ifinfo}. This prevents any of the text from appearing in the printed
-output. (@pxref{Conditionals, , Conditionally Visible Text}). You can
-repeat the brief description from the `Top' node within @code{@@iftex}
-@dots{} @code{@@end iftex} at the beginning of the first chapter, for
-those who read the printed manual. This saves paper and may look
-neater.@refill
-
-You should write the version number of the program to which the manual
-applies in the summary. This helps the reader keep track of which
-manual is for which version of the program. If the manual changes more
-frequently than the program or is independent of it, you should also
-include an edition number for the manual. (The title page should also
-contain this information: see @ref{titlepage, ,

-
-When you take advantage of this feature, you do not need to write the
-`Next', `Previous', and `Up' pointers after the name of a node.
-However, you must write a sectioning command, such as @code{@@chapter}
-or @code{@@section}, on the line immediately following each truncated
-@code{@@node} line. You cannot write a comment line after a node

-
-However, in any document, some information will be too detailed for
-the current context, or incidental to it; use cross references to
-provide access to such information. Also, an on-line help system or a

-sequence from beginning to end. Instead, people look up what they
-need. For this reason, such creations should contain many cross
-references to help readers find other information that they may not
-have read.@refill
-
-In a printed manual, a cross reference results in a page reference,
-unless it is to another manual altogether, in which case the cross

-In Info, a cross reference results in an entry that you can follow using

-
-@item
-A topic description or section name. Often, this is the title of the

-@item
-The name of the Info file in which the reference is located, if it is

-
-Use the @code{@@code} command to indicate text that is a piece of a
-program and which consists of entire syntactic tokens. Enclose the
-text in braces.@refill
-
-Thus, you should use @code{@@code} for an expression in a program, for
-the name of a variable or function used in a program, or for a
-keyword. Also, you should use @code{@@code} for the name of a
-program, such as @code{diff}, that is a name used in the machine. (You
-should write the name of a program in the ordinary text font if you
-regard it as a new English word, such as `Emacs' or `Bison'.)@refill
-
-Use @code{@@code} for environment variables such as @code{TEXINPUTS},
-and other variables.@refill
-
-Use @code{@@code} for command names in command languages that
-resemble programming languages, such as Texinfo or the shell.
-For example, @code{@@code} and @code{@@samp} are produced by writing
-@samp{@@code@{@@@@code@}} and @samp{@@code@{@@@@samp@}} in the Texinfo
-source, respectively.@refill
-
-Note, however, that you should not use @code{@@code} for shell options
-such as @samp{-c} when such options stand alone. (Use @code{@@samp}.)
-Also, an entire shell command often looks better if written using
-@code{@@samp} rather than @code{@@code}. In this case, the rule is to
-choose the more pleasing format.@refill
-
-It is incorrect to alter the case of a word inside an @code{@@code}
-command when it appears at the beginning of a sentence. Most computer
-languages are case sensitive. In C, for example, @code{Printf} is
-different from the identifier @code{printf}, and most likely is a
-misspelling of it. Even in languages which are not case sensitive, it
-is confusing to a human reader to see identifiers spelled in different
-ways. Pick one spelling and always use that. If you do not want to
-start a sentence with a command written all in lower case, you should
-rearrange the sentence.@refill
-
-Do not use the @code{@@code} command for a string of characters shorter
-than a syntactic token. If you are writing about @samp{TEXINPU}, which
-is just a part of the name for the @code{TEXINPUTS} environment
-variable, you should use @code{@@samp}.@refill
-
-In particular, you should not use the @code{@@code} command when writing
-about the characters used in a token; do not, for example, use
-@code{@@code} when you are explaining what letters or printable symbols
-can be used in the names of functions. (Use @code{@@samp}.) Also, you
-should not use @code{@@code} to mark text that is considered input to
-programs unless the input is written in a language that is like a
-programming language. For example, you should not use @code{@@code} for
-the keystroke commands of GNU Emacs (use @code{@@kbd} instead) although
-you may use @code{@@code} for the names of the Emacs Lisp functions that
-the keystroke commands invoke.@refill
-
-In the printed manual, @code{@@code} causes @TeX{} to typeset the
-argument in a typewriter face. In the Info file, it causes the Info
-formatting commands to use single quotation marks around the text.

-
-Usually, in Texinfo, you talk what you type as keyboard entry by
-describing it with @code{@@kbd}: thus, @samp{@@kbd@{C-a@}} for
-@kbd{C-a}. Use @code{@@kbd} in this way when talking about a control
-character that is typed on the keyboard by the user. When talking

-@cindex Creating indices
-
-Using Texinfo, you can generate indices without having to sort and
-collate entries manually. In an index, the entries are listed in
-alphabetical order, together with information on how to find the
-discussion of each entry. In a printed manual, this information
-consists of page numbers. In an Info file, this information is a menu
-entry leading to the first node referenced.@refill
-
-Texinfo provides several predefined kinds of index: an index
-for functions, an index for variables, an index for concepts, and so
-on. You can combine indices or use them for other than their
-canonical purpose. If you wish, you can define your own indices.@refill

-@cindex Entries, making index
-
-When you are making index entries, it is good practice to think of the
-different ways people may look for something. Different people
-@emph{do not} think of the same words when they look something up. A
-helpful index will have items indexed under all the different words
-that people may use. For example, one reader may think it obvious that
-the two-letter names for indices should be listed under ``Indices,
-two-letter names'', since the word ``Index'' is the general concept.
-But another reader may remember the specific concept of two-letter
-names and search for the entry listed as ``Two letter names for
-indices''. A good index will have both entries and will help both
-readers.@refill

-The data to make an index come from many individual indexing commands
-scattered throughout the Texinfo source file. Each command says to add
-one entry to a particular index; after formatting, the index will give
-the current page number or node name as the reference.@refill

-An index entry consists of an indexing command at the beginning of a
-line followed, on the rest of the line, by the entry.@refill

-
-@cindex Writing index entries
-@cindex Index entry writing
-Concept index entries consist of text. The best way to write an index
-is to choose entries that are terse yet clear. If you can do this,
-the index often looks better if the entries are not capitalized, but
-written just as they would appear in the middle of a sentence.
-(Capitalize proper names and acronyms that always call for upper case
-letters.) This is the case convention we use in most GNU manuals'
-indices.
-
-If you don't see how to make an entry terse yet clear, make it longer
-and clear---not terse and confusing. If many of the entries are several
-words long, the index may look better if you use a different convention:
-to capitalize the first word of each entry. But do not capitalize a
-case-sensitive name such as a C or Lisp function name or a shell
-command; that would be a spelling error.
-
-Whichever case convention you use, please use it consistently!
-
-@ignore
-Concept index entries consist of English text. The usual convention
-is to capitalize the first word of each such index entry, unless that
-word is the name of a function, variable, or other such entity that
-should not be capitalized. However, if your concept index entries are
-consistently short (one or two words each) it may look better for each
-regular entry to start with a lower case letter, aside from proper
-names and acronyms that always call for upper case letters. Whichever
-convention you adapt, please be consistent!
-@end ignore
-
-Entries in indices other than the concept index are symbol names in
-programming languages, or program names; these names are usually
-case-sensitive, so use upper and lower case as required for them.
-
-By default, entries for a concept index are printed in a small roman
-font and entries for the other indices are printed in a small
-@code{@@code} font. You may change the way part of an entry is
-printed with the usual Texinfo commands, such as @code{@@file} for
-file names and @code{@@emph} for emphasis (@pxref{Marking

-If you write several identical index entries in different places in a
-Texinfo file, the index in the printed manual will list all the pages to
-which those entries refer. However, the index in the Info file will
-list @strong{only} the node that references the @strong{first} of those
-index entries. Therefore, it is best to write indices in which each
-entry refers to only one place in the Texinfo file. Fortunately, this
-constraint is a feature rather than a loss since it means that the index
-will be easy to use. Otherwise, you could create an index that lists
-several pages for one entry and your reader would not know to which page
-to turn. If you have two identical entries for one topic, change the
-topics slightly, or qualify them to indicate the difference.@refill
-
-You are not actually required to use the predefined indices for their
-canonical purposes. For example, suppose you wish to index some C
-preprocessor macros. You could put them in the function index along
-with actual functions, just by writing @code{@@findex} commands for
-them; then, when you print the ``Function Index'' as an unnumbered
-chapter, you could give it the title `Function and Macro Index' and
-all will be consistent for the reader. Or you could put the macros in
-with the data types by writing @code{@@tindex} commands for them, and
-give that index a suitable title so the reader will understand.

-
-You could put functions into the concept index by writing

-title `Function and Concept Index' and not printing the `Function
-Index' at all; but this is not a robust procedure. It works only if
-your document is never included as part of another
-document that is designed to have a separate function index; if your
-document were to be included with such a document, the functions from
-your document and those from the other would not end up together.
-Also, to make your function names appear in the right font in the

-In addition to the predefined indices, you may use the

-The name of an index should be a two letter word, such as @samp{au}.
-For example:@refill
-

-@@defindex au
-@end example
-
-This defines a new index, called the @samp{au} index. At the same
-time, it creates a new indexing command, @code{@@auindex}, that you

-Texinfo constructs the new indexing command by concatenating the name

-
-Occasionally, you may want to actually insert several consecutive
-spaces, either for purposes of example (what your program does with

-headings or lists. Texinfo supports three commands:
-@code{@@@kbd{SPACE}}, @code{@@@kbd{TAB}}, and @code{@@@kbd{NL}}, all of

-@code{@@@kbd{SPACE}} represents an @samp{@@} character followed by a

-belongs. The @code{@@deffn} command possesses three predefined,
-specialized variations, @code{@@defun}, @code{@@defmac}, and
-@code{@@defspec}, that specify the category for you: ``Function'',
-``Macro'', and ``Special Form'' respectively. (In Lisp, a special form

-The @code{@@deffn} command is the general definition command for

-@section Footnote Commands
-
-In Texinfo, footnotes are created with the @code{@@footnote} command.
-This command is followed immediately by a left brace, then by the text
-of the footnote, and then by a terminating right brace. Footnotes may
-be of any length (they will be broken across pages if necessary), but
-are usually short. The template is:
-
-@example
-ordinary text@@footnote@{@var{text of footnote}@}
-@end example
-
-As shown here, the @code{@@footnote} command should come right after the
-text being footnoted, with no intervening space; otherwise, the
-formatters the footnote mark might end up starting up a line.
-
-For example, this clause is followed by a sample
-footnote@footnote{Here is the sample footnote.}; in the Texinfo
-source, it looks like this:@refill
-
-@example
-@dots{}a sample footnote@@footnote@{Here is the sample
-footnote.@}; in the Texinfo source@dots{}
-@end example
-
-@strong{Warning:} Don't use footnotes in the argument of the
-@code{@@item} command for a @code{@@table} table. This doesn't work, and
-because of limitations of @TeX{}, there is no way to fix it. You must
-put the footnote into the body text of the table.
-
-In a printed manual or book, the reference mark for a footnote is a
-small, superscripted number; the text of the footnote appears at the
-bottom of the page, below a horizontal line.@refill
-
-In Info, the reference mark for a footnote is a pair of parentheses
-with the footnote number between them, like this: @samp{(1)}.@refill
-

-@samp{Footnotes} within it. Each footnote begins with an
-@samp{(@var{n})} reference mark.@refill

-@cindex @samp{@r{Separate}} footnote style

-In the `Separate' node style, all the footnotes for a single
-node are placed in an automatically constructed node of
-their own. In this style, a ``footnote reference'' follows
-each @samp{(@var{n})} reference mark in the body of the
-node. The footnote reference is actually a cross reference
-which you use to reach the footnote node.@refill
-
-The name of the node containing the footnotes is constructed
-by appending @w{@samp{-Footnotes}} to the name of the node
-that contains the footnotes. (Consequently, the footnotes'

-@w{@file{Footnotes-Footnotes}}!) The footnotes' node has an

-This is a string.

-You can write an @code{@@value} command within a paragraph; but you

-If you write the @code{@@set} command like this:
-
-@example
-@@set foo
-@end example

-without specifying a string, the value of @code{foo} is an empty string.

-
-@cindex Backslash, and macros
-Thus, the arguments and parameters are separated by commas and delimited
-by braces; any whitespace after (but not before) a comma is ignored. To
-insert a comma, brace, or backslash in an argument, prepend a backslash,
-as in
-
-@example
-@@@var{macro-name} @{\\\@{\@}\,@}
-@end example
-
-@noindent
-which will pass the (almost certainly error-producing) argument
-@samp{\@{@},} to @var{macro-name}.

-If the macro is defined to take a single argument, and is invoked
-without any braces, the entire rest of the line after the macro name is
-supplied as the argument. For example:

-@example
-@@macro bar @{p@}
-Twice: \p\, \p\.

-writes an output file of unsorted index data. (The @code{texi2dvi}
-command automatically generates indices; see @ref{Format with texi2dvi,,
-Format using @code{texi2dvi}}.) To generate a printed index after
-running the @code{tex} command, you first need a sorted index to work
-from. The @code{texindex} command sorts indices. (The source file
-@file{texindex.c} comes as part of the standard Texinfo distribution,
-among other places.)@refill
-
-@cindex Names of index files
-The @code{tex} formatting command outputs unsorted index files under
-names that obey a standard convention: the name of your main input file
-with any @samp{.tex} (or similar, @pxref{tex invocation,,, web2c,
-Web2c}) extension removed, followed by the two letter names of indices.
-For example, the raw index output files for the input file
-@file{foo.texinfo} would be @file{foo.cp}, @file{foo.vr}, @file{foo.fn},
-@file{foo.tp}, @file{foo.pg} and @file{foo.ky}. Those are exactly the
-arguments to give to @code{texindex}.@refill
-
-@need 1000
-@cindex Wildcards
-@cindex Globbing
-Instead of specifying all the unsorted index file names explicitly, you
-can use @samp{??} as shell wildcards and give the command in this
-form:@refill
-
-@example
-texindex foo.??
-@end example
-
-@noindent
-This command will run @code{texindex} on all the unsorted index files,
-including any that you have defined yourself using @code{@@defindex}
-or @code{@@defcodeindex}. (You may execute @samp{texindex foo.??}
-even if there are similarly named files with two letter extensions
-that are not index files, such as @samp{foo.el}. The @code{texindex}
-command reports but otherwise ignores such files.)@refill
-
-For each file specified, @code{texindex} generates a sorted index file
-whose name is made by appending @samp{s} to the input file name. The
-@code{@@printindex} command knows to look for a file of that name
-(@pxref{Printing Indices & Menus}). @code{texindex} does not alter the
-raw index output file.@refill
-
-After you have sorted the indices, you need to rerun the @code{tex}
-formatting command on the Texinfo file. This regenerates the DVI file,
-this time with up-to-date index entries.
-
-Finally, you may need to run @code{tex} one more time, to get the page
-numbers in the cross-references correct.
-
-To summarize, this is a four step process:
-
-@enumerate
-@item
-Run @code{tex} on your Texinfo file. This generates a DVI file (with
-undefined cross-references and no indices), and the raw index files
-(with two letter extensions).
-
-@item
-Run @code{texindex} on the raw index files. This creates the
-corresponding sorted index files (with three letter extensions).
-
-@item
-Run @code{tex} again on your Texinfo file. This regenerates the DVI
-file, this time with indices and defined cross-references, but with page
-numbers for the cross-references from last time, generally incorrect.
-
-@item
-Run @code{tex} one last time. This time the correct page numbers are
-written for the cross-references.
-@end enumerate
-
-@pindex texi2dvi
-Alternatively, it's a one-step process: run @code{texi2dvi}.
-
-You need not run @code{texindex} each time after you run @code{tex}. If
-you do not, on the next run, the @code{tex} formatting command will use
-whatever sorted index files happen to exist from the previous use of
-@code{texindex}. This is usually ok while you are
-debugging.@refill

-
-The @code{texi2dvi} command is a shell script that automatically runs
-both @code{tex} and @code{texindex} as many times as necessary to
-produce a DVI file with up-to-date, sorted indices. It simplifies the
-@code{tex}---@code{texindex}---@code{tex} sequence described in the

-The precise command to print a DVI file depends on your system
-installation, but @samp{lpr -d} is common. The command may require the
-DVI file name without any extension or with a @samp{.dvi}
-extension. (If it is @samp{lpr}, you must include the @samp{.dvi}.)
-
-The following commands, for example, will (probably) suffice to sort the
-indices, format, and print the @cite{Bison Manual}:

-@group
-tex bison.texinfo
-texindex bison.??
-tex bison.texinfo

-Every Texinfo file that is to be input to @TeX{} must begin with a

-
-@example
-\input texinfo
-@@setfilename @var{arg-not-used-by-@TeX{}}
-@end example
-
-@noindent
-The first command instructs @TeX{} to load the macros it needs to
-process a Texinfo file and the second command opens auxiliary files.
-
-Every Texinfo file must end with a line that terminates @TeX{}'s
-processing and forces out unfinished pages:
-
-@example
-@@bye
-@end example
-
-Strictly speaking, these lines are all a Texinfo file needs to be
-processed successfully by @TeX{}.
-
-Usually, however, the beginning includes an @code{@@settitle} command to
-define the title of the printed manual, an @code{@@setchapternewpage}
-command, a title page, a copyright page, and permissions. Besides an
-@code{@@bye}, the end of a file usually includes indices and a table of

-Alternatively, you can put @file{texinfo.tex} in the current directory

-
-@pindex epsf.tex@r{, installing}
-Also, you should install @file{epsf.tex} in the same place as

-@cindex Customizing of @TeX{} for Texinfo
-@cindex Site-wide Texinfo configuration file
-Optionally, you may create an additional @file{texinfo.cnf}, and install

-command (@pxref{setfilename,, @code{@@setfilename}}). You can put any
-commands you like there according to local site-wide conventions, and
-they will be read by @TeX{} when processing any Texinfo document. For
-example, if @file{texinfo.cnf} contains the a single line
-@samp{@@afourpaper} (@pxref{A4 Paper}), then all Texinfo documents will
-be processed with that page size in effect. If you have nothing to put
-in @file{texinfo.cnf}, you do not need to create it.
-
-@vindex TEXINPUTS
-If neither of the above locations for these system files suffice for

-@file{texinfo.tex} and @file{texinfo.cnf} (and any other file @TeX{}
-might read), is to set the @code{TEXINPUTS} environment variable in your
-@file{.cshrc} or @file{.profile} file.

-Which you use of @file{.cshrc} or @file{.profile} depends on
-whether you use a Bourne shell-compatible (@code{sh}, @code{bash},
-@code{ksh}, @dots{}) or C shell-compatible (@code{csh}, @code{tcsh})
-command interpreter. The latter read the @file{.cshrc} file for
-initialization information, and the former read @file{.profile}.
-
-In a @file{.cshrc} file, you could use the following @code{csh} command
-sequence:
-
-@example
-setenv TEXINPUTS .:/home/me/mylib:/usr/lib/tex/macros

-export TEXINPUTS
-@end group
-@end example

-This would cause @TeX{} to look for @file{\input} file first in the current

-The @code{makeinfo} utility creates an Info file from a Texinfo source
-file more quickly than either of the Emacs formatting commands and
-provides better error messages. We recommend it. @code{makeinfo} is a
-C program that is independent of Emacs. You do not need to run Emacs to
-use @code{makeinfo}, which means you can use @code{makeinfo} on machines
-that are too small to run Emacs. You can run @code{makeinfo} in
-any one of three ways: from an operating system shell, from a shell
-inside Emacs, or by typing a key command in Texinfo mode in Emacs.
-@refill
-
-The @code{texinfo-format-region} and the @code{texinfo-format-buffer}
-commands are useful if you cannot run @code{makeinfo}. Also, in some
-circumstances, they format short regions or buffers more quickly than
-@code{makeinfo}.@refill

-
-The @code{makeinfo} command takes a number of options. Most often,
-options are used to set the value of the fill column and specify the
-footnote style. Each command line option is a word preceded by
-@samp{--} or a letter preceded by @samp{-}. You can use abbreviations
-for the long option names as long as they are unique.@refill
-
-For example, you could use the following shell command to create an Info
-file for @file{bison.texinfo} in which each line is filled to only 68
-columns:@refill
-
-@example
-makeinfo --fill-column=68 bison.texinfo
-@end example
-
-You can write two or more options in sequence, like this:@refill
-
-@example
-makeinfo --no-split --fill-column=70 @dots{}
-@end example
-
-@noindent
-This would keep the Info file together as one possibly very long
-file and would also set the fill column to 70.@refill
-
-The options are:
-
-@table @code
-
-@item -D @var{var}
-@opindex -D @var{var}
-Cause the variable @var{var} to be defined. This is equivalent to
-@code{@@set @var{var}} in the Texinfo file (@pxref{set clear value}).
-
-@item --error-limit=@var{limit}
-@opindex --error-limit=@var{limit}
-Set the maximum number of errors that @code{makeinfo} will report
-before exiting (on the assumption that continuing would be useless);
-default 100.
-
-@need 150
-@item --fill-column=@var{width}
-@opindex --fill-column=@var{width}
-Specify the maximum number of columns in a line; this is the right-hand
-edge of a line. Paragraphs that are filled will be filled to this
-width. (Filling is the process of breaking up and connecting lines so
-that lines are the same length as or shorter than the number specified
-as the fill column. Lines are broken between words.) The default value
-is 72.
-
-@item --footnote-style=@var{style}
-@opindex --footnote-style=@var{style}
-Set the footnote style to @var{style}, either @samp{end} for the end
-node style (the default) or @samp{separate} for the separate node style.
-The value set by this option overrides the value set in a Texinfo file
-by an @code{@@footnotestyle} command (@pxref{Footnotes}). When the
-footnote style is @samp{separate}, @code{makeinfo} makes a new node
-containing the footnotes found in the current node. When the footnote
-style is @samp{end}, @code{makeinfo} places the footnote references at
-the end of the current node.
-
-@item --force
-@opindex --force
-Ordinarily, if the input file has errors, the output files are not
-created. With this option, they are preserved.
-
-@item --help
-@opindex --help
-Print a usage message listing all available options, then exit successfully.
-
-@item -I @var{dir}
-@opindex -I @var{dir}
-Add @code{dir} to the directory search list for finding files that are
-included using the @code{@@include} command. By default,
-@code{makeinfo} searches only the current directory.
-
-@item --no-headers
-@opindex --no-headers
-Do not include menus or node lines in the output. This results in an
-@sc{ascii} file that you cannot read in Info since it does not contain
-the requisite nodes or menus. It is primarily useful to extract certain
-pieces of a manual into separate files to be included in a distribution,
-such as @file{INSTALL} files.
-
-@item --no-split
-@opindex --no-split
-Suppress the splitting stage of @code{makeinfo}. By default, large
-output files (where the size is greater than 70k bytes) are split into
-smaller subfiles, each one approximately 50k bytes.
-
-@item --no-pointer-validate
-@itemx --no-validate
-@opindex --no-pointer-validate
-@opindex --no-validate
-Suppress the pointer-validation phase of @code{makeinfo}. Normally,
-after a Texinfo file is processed, some consistency checks are made to
-ensure that cross references can be resolved, etc.
-@xref{Pointer Validation}.@refill
-
-@item --no-warn
-@opindex --no-warn
-Suppress warning messages (but @emph{not} error messages). You might
-want this if the file you are creating has examples of Texinfo cross
-references within it, and the nodes that are referenced do not actually
-exist.
-
-@item --no-number-footnotes
-@opindex --no-number-footnotes
-Suppress automatic footnote numbering. By default, @code{makeinfo}
-numbers each footnote sequentially in a single node, resetting the
-current footnote number to 1 at the start of each node.
-
-@item --output=@var{file}
-@itemx -o @var{file}
-@opindex --output=@var{file}
-@opindex -o @var{file}
-Specify that the output should be directed to @var{file} and not to the
-file name specified in the @code{@@setfilename} command found in the
-Texinfo source (@pxref{setfilename}). If @var{file} is @samp{-}, output
-goes to standard output and @samp{--no-split} is implied.
-
-@item -P @var{dir}
-@opindex -P @var{dir}
-Prepend @code{dir} to the directory search list for @code{@@include}.
-See @samp{-I} for more details.
-
-@item --paragraph-indent=@var{indent}
-@opindex --paragraph-indent=@var{indent}
-Set the paragraph indentation style to @var{indent}. The value set by
-this option overrides the value set in a Texinfo file by an
-@code{@@paragraphindent} command (@pxref{paragraphindent}). The value
-of @var{indent} is interpreted as follows:
-
-@table @asis
-@item @samp{asis}
-Preserve any existing indentation at the starts of paragraphs.
-
-@item @samp{0} or @samp{none}
-Delete any existing indentation.
-
-@item @var{num}
-Indent each paragraph by that number of spaces.
-@end table
-
-@item --reference-limit=@var{limit}
-@opindex --reference-limit=@var{limit}
-Set the value of the number of references to a node that
-@code{makeinfo} will make without reporting a warning. If a node has more
-than this number of references in it, @code{makeinfo} will make the
-references but also report a warning. The default is 1000.
-
-@item -U @var{var}
-Cause @var{var} to be undefined. This is equivalent to
-@code{@@clear @var{var}} in the Texinfo file (@pxref{set clear value}).
-

-not need to make a large buffer to hold the whole of a large Info

-The first part of the menu entry is the menu entry name, followed by a

-
-The name of an Info file often has a @file{.info} extension. Thus, the
-Info file for GDB might be called either @file{gdb} or @file{gdb.info}.
-The Info reader programs automatically try the file name both with and

-entry should use just @samp{gdb} for the file name, not @samp{gdb.info}.

-@cindex Info installed in another directory
-@cindex Another Info directory
-
-If an Info file is not in the @file{info} directory, there are three
-ways to specify its location:@refill
-
-@itemize @bullet
-@item
-Write the pathname in the @file{dir} file as the second part of the
-menu.@refill
-
-@item
-If you are using Emacs, list the name of the file in a second @file{dir}
-file, in its directory; and then add the name of that directory to the
-@code{Info-directory-list} variable in your personal or site
-initialization file.
-
-This tells Emacs where to look for @file{dir} files. Emacs merges the
-files named @file{dir} from each of the listed directories. (In Emacs
-version 18, you can set the @code{Info-directory} variable to the name
-of only one directory.)@refill
-
-@item
-Specify the Info directory name in the @code{INFOPATH} environment
-variable in your @file{.profile} or @file{.cshrc} initialization file.
-(Only you and others who set this environment variable will be able to
-find Info files whose location is specified this way.)@refill
-@end itemize
-
-For example, to reach a test file in the @file{/home/bob/manuals}
-directory, you could add an entry like this to the menu in the
-@file{dir} file:@refill
-
-@example
-* Test: (/home/bob/manuals/info-test). Bob's own test file.
-@end example
-
-@noindent
-In this case, the absolute file name of the @file{info-test} file is
-written as the second part of the menu entry.@refill
-
-@vindex Info-directory-list
-Alternatively, you could write the following in your @file{.emacs}
-file:@refill
-
-@example
-@group
-(setq Info-directory-list
- '("/home/bob/manuals"
- "/usr/local/info"))
-@end group
-@end example
-
-@c reworded to avoid overfill hbox
-This tells Emacs to merge the @file{dir} file from the
-@file{/home/bob/manuals} directory with the @file{dir} file from the
-@file{/usr/local/info} directory. Info will list the
-@file{/home/bob/manuals/info-test} file as a menu entry in the
-@file{/home/bob/manuals/dir} file.@refill
-
-@vindex INFOPATH
-Finally, you can tell Info where to look by setting the @code{INFOPATH}
-environment variable in your @file{.cshrc} or @file{.profile} file. If
-you use a Bourne-compatible shell such as @code{sh} or @code{bash} for
-your shell command interpreter, you set the @code{INFOPATH} environment
-variable in the @file{.profile} initialization file; but if you use
-@code{csh} or @code{tcsh}, you must set the variable in the
-@file{.cshrc} initialization file. The two types of shells use
-different syntax.
-
-@itemize @bullet
-@item
-In a @file{.cshrc} file, you could set the @code{INFOPATH}
-variable as follows:@refill
-
-@smallexample
-setenv INFOPATH .:~/manuals:/usr/local/emacs/info
-@end smallexample
-
-@item
-In a @file{.profile} file, you would achieve the same effect by
-writing:@refill
-
-@smallexample
-INFOPATH=.:$HOME/manuals:/usr/local/emacs/info
-export INFOPATH
-@end smallexample
-@end itemize
-
-@noindent
-The @samp{.} indicates the current directory as usual. Emacs uses the
-@code{INFOPATH} environment variable to initialize the value of Emacs's
-own @code{Info-directory-list} variable.
-
-@cindex @samp{:} @r{last in @code{INFOPATH}}
-However you set @code{INFOPATH}, if its last character is a colon, this
-is replaced by the default (compiled-in) path. This gives you a way to
-augment the default path with new directories without having to list all
-the standard places. For example (using @code{sh} syntax:
-
-@example
-INFOPATH=/local/info:
-export INFOPATH
-@end example
-
-@noindent
-will search @file{/local/info} first, then the standard directories.
-Leading or doubled colons are not treated specially.

-@node Installing Dir Entries, Invoking install-info, Other Info Directories, Install an Info File
-@section Installing Info Directory Files
-
-When you install an Info file onto your system, you can use the program
-@code{install-info} to update the Info directory file @file{dir}.
-Normally the makefile for the package runs @code{install-info}, just
-after copying the Info file into its proper installed location.
-
-@findex dircategory
-@findex direntry
-In order for the Info file to work with @code{install-info}, you should
-use the commands @code{@@dircategory} and @code{@@direntry} in the
-Texinfo source file. Use @code{@@direntry} to specify the menu entry to
-add to the Info directory file, and use @code{@@dircategory} to specify
-which part of the Info directory to put it in. Here is how these
-commands are used in this manual:
-
-@smallexample
-@@dircategory Texinfo documentation system
-@@direntry
-* Texinfo: (texinfo). The GNU documentation format.
-* install-info: (texinfo)Invoking install-info. @dots{}
-@dots{}
-@@end direntry
-@end smallexample
-
-Here's what this produces in the Info file:
-
-@smallexample
-INFO-DIR-SECTION Texinfo documentation system
-START-INFO-DIR-ENTRY
-* Texinfo: (texinfo). The GNU documentation format.
-* install-info: (texinfo)Invoking install-info. @dots{}
-@dots{}
-END-INFO-DIR-ENTRY
-@end smallexample
-
-@noindent
-The @code{install-info} program sees these lines in the Info file, and
-that is how it knows what to do.
-
-Always use the @code{@@direntry} and @code{@@dircategory} commands near
-the beginning of the Texinfo input, before the first @code{@@node}
-command. If you use them later on in the input, @code{install-info}
-will not notice them.
-
-If you use @code{@@dircategory} more than once in the Texinfo source,
-each usage specifies one category; the new menu entry is added to the
-Info directory file in each of the categories you specify. If you use
-@code{@@direntry} more than once, each usage specifies one menu entry;
-each of these menu entries is added to the directory in each of the
-specified categories.

-@node Invoking install-info, , Installing Dir Entries, Install an Info File
-@section Invoking install-info
-
-@pindex install-info
-
-@code{install-info} inserts menu entries from an Info file into the
-top-level @file{dir} file in the Info system (see the previous sections
-for an explanation of how the @file{dir} file works). It's most often
-run as part of software installation, or when constructing a dir file
-for all manuals on a system. Synopsis:
-
-@example
-install-info [@var{option}]@dots{} [@var{info-file} [@var{dir-file}]]
-@end example
-
-If @var{info-file} or @var{dir-file} are not specified, the various
-options (described below) that define them must be. There are no
-compile-time defaults, and standard input is never used.
-@code{install-info} can read only one info file and write only one dir
-file per invocation.
-
-@cindex @file{dir}, created by @code{install-info}
-If @var{dir-file} (however specified) does not exist,
-@code{install-info} creates it if possible (with no entries).
-
-Options:
-
-@table @code
-@item --delete
-@opindex --delete
-Delete the entries in @var{info-file} from @var{dir-file}. The file
-name in the entry in @var{dir-file} must be @var{info-file} (except for
-an optional @samp{.info} in either one). Don't insert any new entries.
-
-@item --dir-file=@var{name}
-@opindex --dir-file=@var{name}
-Specify file name of the Info directory file. This is equivalent to
-using the @var{dir-file} argument.
-
-@item --entry=@var{text}
-@opindex --entry=@var{text}
-Insert @var{text} as an Info directory entry; @var{text} should have the
-form of an Info menu item line plus zero or more extra lines starting
-with whitespace. If you specify more than one entry, they are all
-added. If you don't specify any entries, they are determined from
-information in the Info file itself.
-
-@item --help
-@opindex --help
-Display a usage message listing basic usage and all available options,
-then exit successfully.
-
-@item --info-file=@var{file}

-@opindex --info-dir=@var{dir}
-Equivalent to @samp{--dir-file=@var{dir}/dir}.
-
-@item --item=@var{text}
-@opindex --item=@var{text}
-Same as @samp{--entry=@var{text}}. An Info directory entry is actually
-a menu item.
-
-@item --quiet

-Suppress warnings.
-
-@item --remove

-@appendix Tips and Hints
-
-Here are some tips for writing Texinfo documentation:@refill
-
-@cindex Tips
-@cindex Usage tips
-@cindex Hints
-@itemize @bullet
-@item
-Write in the present tense, not in the past or the future.
-
-@item
-Write actively! For example, write ``We recommend that @dots{}'' rather
-than ``It is recommended that @dots{}''.
-
-@item
-Use 70 or 72 as your fill column. Longer lines are hard to read.
-
-@item
-Include a copyright notice and copying permissions.
-@end itemize
-
-@subsubheading Index, Index, Index!
-
-Write many index entries, in different ways.
-Readers like indices; they are helpful and convenient.
-
-Although it is easiest to write index entries as you write the body of
-the text, some people prefer to write entries afterwards. In either
-case, write an entry before the paragraph to which it applies. This
-way, an index entry points to the first page of a paragraph that is
-split across pages.
-
-Here are more hints we have found valuable:
-
-@itemize @bullet
-@item
-Write each index entry differently, so each entry refers to a different
-place in the document.
-
-@item
-Write index entries only where a topic is discussed significantly. For
-example, it is not useful to index ``debugging information'' in a
-chapter on reporting bugs. Someone who wants to know about debugging
-information will certainly not find it in that chapter.
-
-@item
-Consistently capitalize the first word of every concept index entry,
-or else consistently use lower case. Terse entries often call for
-lower case; longer entries for capitalization. Whichever case
-convention you use, please use one or the other consistently! Mixing
-the two styles looks bad.
-
-@item
-Always capitalize or use upper case for those words in an index for
-which this is proper, such as names of countries or acronyms. Always
-use the appropriate case for case-sensitive names, such as those in C or
-Lisp.
-
-@item
-Write the indexing commands that refer to a whole section immediately
-after the section command, and write the indexing commands that refer to
-the paragraph before the paragraph.
-
-@need 1000
-In the example that follows, a blank line comes after the index
-entry for ``Leaping'':
-
-@example
-@group
-@@section The Dog and the Fox
-@@cindex Jumping, in general
-@@cindex Leaping
-
-@@cindex Dog, lazy, jumped over
-@@cindex Lazy dog jumped over
-@@cindex Fox, jumps over dog
-@@cindex Quick fox jumps over dog
-The quick brown fox jumps over the lazy dog.
-@end group
-@end example
-
-@noindent
-(Note that the example shows entries for the same concept that are
-written in different ways---@samp{Lazy dog}, and @samp{Dog, lazy}---so
-readers can look up the concept in different ways.)
-@end itemize
-
-@subsubheading Blank Lines
-
-@itemize @bullet
-@item
-Insert a blank line between a sectioning command and the first following
-sentence or paragraph, or between the indexing commands associated with
-the sectioning command and the first following sentence or paragraph, as
-shown in the tip on indexing. Otherwise, a formatter may fold title and
-paragraph together.
-
-@item
-Always insert a blank line before an @code{@@table} command and after an
-@code{@@end table} command; but never insert a blank line after an
-@code{@@table} command or before an @code{@@end table} command.
-
-@need 1000
-For example,
-
-@example
-@group
-Types of fox:
-
-@@table @@samp
-@@item Quick
-Jump over lazy dogs.
-@end group
-
-@group
-@@item Brown
-Also jump over lazy dogs.
-@@end table
-
-@end group
-@group
-@@noindent
-On the other hand, @dots{}
-@end group
-@end example
-
-Insert blank lines before and after @code{@@itemize} @dots{} @code{@@end
-itemize} and @code{@@enumerate} @dots{} @code{@@end enumerate} in the
-same way.
-@end itemize
-
-@subsubheading Complete Phrases
-
-Complete phrases are easier to read than @dots{}
-
-@itemize @bullet
-@item
-Write entries in an itemized list as complete sentences; or at least, as
-complete phrases. Incomplete expressions @dots{} awkward @dots{} like
-this.
-
-@item
-Write the prefatory sentence or phrase for a multi-item list or table as
-a complete expression. Do not write ``You can set:''; instead, write
-``You can set these variables:''. The former expression sounds cut off.
-@end itemize
-
-@subsubheading Editions, Dates and Versions
-
-Write the edition and version numbers and date in three places in every
-manual:
-
-@enumerate
-@item
-In the first @code{@@ifinfo} section, for people reading the Texinfo file.
-
-@item
-In the @code{@@titlepage} section, for people reading the printed manual.
-
-@item
-In the `Top' node, for people reading the Info file.
-@end enumerate
-
-@noindent
-Also, it helps to write a note before the first @code{@@ifinfo}
-section to explain what you are doing.
-
-@need 800
-@noindent
-For example:
-
-@example
-@group
-@@c ===> NOTE! <==
-@@c Specify the edition and version numbers and date
-@@c in *three* places:
-@@c 1. First ifinfo section 2. title page 3. top node
-@@c To find the locations, search for !!set
-@end group
-
-@group
-@@ifinfo
-@@c !!set edition, date, version
-This is Edition 4.03, January 1992,
-of the @@cite@{GDB Manual@} for GDB Version 4.3.
-@dots{}
-@end group
-@end example
-
-@noindent
----or use @code{@@set} and @code{@@value}
-(@pxref{value Example, , @code{@@value} Example}).
-
-@subsubheading Definition Commands
-
-Definition commands are @code{@@deffn}, @code{@@defun},
-@code{@@defmac}, and the like, and enable you to write descriptions in
-a uniform format.@refill
-
-@itemize @bullet
-@item
-Write just one definition command for each entity you define with a
-definition command. The automatic indexing feature creates an index
-entry that leads the reader to the definition.
-
-@item
-Use @code{@@table} @dots{} @code{@@end table} in an appendix that
-contains a summary of functions, not @code{@@deffn} or other definition
-commands.
-@end itemize
-
-@subsubheading Capitalization
-
-@itemize @bullet
-@item
-Capitalize ``Texinfo''; it is a name. Do not write the @samp{x} or
-@samp{i} in upper case.
-
-@item
-Capitalize ``Info''; it is a name.
-
-@item
-Write @TeX{} using the @code{@@TeX@{@}} command. Note the uppercase
-@samp{T} and @samp{X}. This command causes the formatters to
-typeset the name according to the wishes of Donald Knuth, who wrote
-@TeX{}.
-@end itemize
-
-@subsubheading Spaces
-
-Do not use spaces to format a Texinfo file, except inside of
-@code{@@example} @dots{} @code{@@end example} and similar commands.
-
-@need 700
-For example, @TeX{} fills the following:
-
-@example
-@group
- @@kbd@{C-x v@}
- @@kbd@{M-x vc-next-action@}
- Perform the next logical operation
- on the version-controlled file
- corresponding to the current buffer.
-@end group
-@end example
-
-@need 950
-@noindent
-so it looks like this:
-
-@iftex
-@quotation
- @kbd{C-x v}
- @kbd{M-x vc-next-action}
- Perform the next logical operation on the version-controlled file
- corresponding to the current buffer.
-@end quotation
-@end iftex
-@ifinfo
-@quotation
-`C-x v' `M-x vc-next-action' Perform the next logical operation on the
-version-controlled file corresponding to the current buffer.
-@end quotation
-@end ifinfo
-
-@noindent
-In this case, the text should be formatted with
-@code{@@table}, @code{@@item}, and @code{@@itemx}, to create a table.
-
-@subsubheading @@code, @@samp, @@var, and @samp{---}
-
-@itemize @bullet
-@item
-Use @code{@@code} around Lisp symbols, including command names.
-For example,
-
-@example
-The main function is @@code@{vc-next-action@}, @dots{}
-@end example
-
-@item
-Avoid putting letters such as @samp{s} immediately after an
-@samp{@@code}. Such letters look bad.
-
-@item
-Use @code{@@var} around meta-variables. Do not write angle brackets
-around them.
-
-@item
-Use three hyphens in a row, @samp{---}, to indicate a long dash. @TeX{}
-typesets these as a long dash and the Info formatters reduce three
-hyphens to two.
-@end itemize
-
-@subsubheading Periods Outside of Quotes
-
-Place periods and other punctuation marks @emph{outside} of quotations,
-unless the punctuation is part of the quotation. This practice goes
-against publishing conventions in the United States, but enables the
-reader to distinguish between the contents of the quotation and the
-whole passage.
-
-For example, you should write the following sentence with the period
-outside the end quotation marks:
-
-@example
-Evidently, @samp{au} is an abbreviation for ``author''.
-@end example
-
-@noindent
-since @samp{au} does @emph{not} serve as an abbreviation for
-@samp{author.} (with a period following the word).
-
-@subsubheading Introducing New Terms
-
-@itemize @bullet
-@item
-Introduce new terms so that a reader who does not know them can
-understand them from context; or write a definition for the term.
-
-For example, in the following, the terms ``check in'', ``register'' and
-``delta'' are all appearing for the first time; the example sentence should be
-rewritten so they are understandable.
-
-@quotation
-The major function assists you in checking in a file to your
-version control system and registering successive sets of changes to
-it as deltas.
-@end quotation
-
-@item
-Use the @code{@@dfn} command around a word being introduced, to indicate
-that the reader should not expect to know the meaning already, and
-should expect to learn the meaning from this passage.
-@end itemize
-
-@subsubheading @@pxref
-
-@c !!! maybe include this in the tips on pxref
-@ignore
-By the way, it is okay to use pxref with something else in front of
-it within the parens, as long as the pxref is followed by the close
-paren, and the material inside the parens is not part of a larger
-sentence. Also, you can use xref inside parens as part of a complete
-sentence so long as you terminate the cross reference with punctuation.
-@end ignore
-Absolutely never use @code{@@pxref} except in the special context for
-which it is designed: inside parentheses, with the closing parenthesis
-following immediately after the closing brace. One formatter
-automatically inserts closing punctuation and the other does not. This
-means that the output looks right both in printed output and in an Info
-file, but only when the command is used inside parentheses.
-
-@subsubheading Invoking from a Shell
-
-You can invoke programs such as Emacs, GCC, and @code{gawk} from a
-shell. The documentation for each program should contain a section that
-describes this. Unfortunately, if the node names and titles for these
-sections are all different, readers find it hard to search for the
-section.@refill
-
-Name such sections with a phrase beginning with the word
-@w{`Invoking @dots{}'}, as in `Invoking Emacs'; this way
-users can find the section easily.
-
-@subsubheading ANSI C Syntax
-
-When you use @code{@@example} to describe a C function's calling
-conventions, use the ANSI C syntax, like this:@refill
-
-@example
-void dld_init (char *@@var@{path@});
-@end example
-
-@noindent
-And in the subsequent discussion, refer to the argument values by
-writing the same argument names, again highlighted with
-@code{@@var}.@refill
-
-@need 800
-Avoid the obsolete style that looks like this:@refill
-
-@example
-#include <dld.h>
-
-dld_init (path)
-char *path;
-@end example
-
-Also, it is best to avoid writing @code{#include} above the
-declaration just to indicate that the function is declared in a
-header file. The practice may give the misimpression that the
-@code{#include} belongs near the declaration of the function. Either
-state explicitly which header file holds the declaration or, better
-yet, name the header file used for a group of functions at the
-beginning of the section that describes the functions.@refill
-
-@subsubheading Bad Examples
-
-Here are several examples of bad writing to avoid:
-
-In this example, say, `` @dots{} you must @code{@@dfn}@{check
-in@} the new version.'' That flows better.
-
-@quotation
-When you are done editing the file, you must perform a
-@code{@@dfn}@{check in@}.
-@end quotation
-
-In the following example, say, ``@dots{} makes a unified interface such as VC
-mode possible.''
-
-@quotation
-SCCS, RCS and other version-control systems all perform similar
-functions in broadly similar ways (it is this resemblance which makes
-a unified control mode like this possible).
-@end quotation
-
-And in this example, you should specify what `it' refers to:
-
-@quotation
-If you are working with other people, it assists in coordinating
-everyone's changes so they do not step on each other.
-@end quotation
-
-@subsubheading And Finally @dots{}
-
-@itemize @bullet
-@item
-Pronounce @TeX{} as if the @samp{X} were a Greek `chi', as the last
-sound in the name `Bach'. But pronounce Texinfo as in `speck':
-``teckinfo''.
-
-@item
-Write notes for yourself at the very end of a Texinfo file after the
-@code{@@bye}. None of the formatters process text after the
-@code{@@bye}; it is as if the text were within @code{@@ignore} @dots{}
-@code{@@end ignore}.

-In the @code{@@ifinfo} section, the summary sentence is followed by a

-the copying permission paragraphs is enclosed in @code{@@ignore} and
-@code{@@end ignore} commands. This paragraph states that the Texinfo
-file can be processed through @TeX{} and printed, provided the printed

-is not made part of the Info file since it is not relevant to the Info

-
-In the printed manual, the Free Software Foundation copying permission

-@findex include
-
-To include another file within a Texinfo file, write the
-@code{@@include} command at the beginning of a line and follow it on
-the same line by the name of a file to be included. For
-example:@refill
-
-@example
-@@include buffers.texi
-@end example
-
-An included file should simply be a segment of text that you expect to
-be included as is into the overall or @dfn{outer} Texinfo file; it
-should not contain the standard beginning and end parts of a Texinfo
-file. In particular, you should not start an included file with a
-line saying @samp{\input texinfo}; if you do, that phrase is inserted
-into the output file as is. Likewise, you should not end an included
-file with an @code{@@bye} command; nothing after @code{@@bye} is
-formatted.@refill
-
-In the past, you were required to write an @code{@@setfilename} line at the
-beginning of an included file, but no longer. Now, it does not matter
-whether you write such a line. If an @code{@@setfilename} line exists
-in an included file, it is ignored.@refill
-
-Conventionally, an included file begins with an @code{@@node} line that
-is followed by an @code{@@chapter} line. Each included file is one
-chapter. This makes it easy to use the regular node and menu creating
-and updating commands to create the node pointers and menus within the
-included file. However, the simple Emacs node and menu creating and
-updating commands do not work with multiple Texinfo files. Thus you
-cannot use these commands to fill in the `Next', `Previous', and `Up'
-pointers of the @code{@@node} line that begins the included file. Also,
-you cannot use the regular commands to create a master menu for the
-whole file. Either you must insert the menus and the `Next',
-`Previous', and `Up' pointers by hand, or you must use the GNU Emacs
-Texinfo mode command, @code{texinfo-multiple-files-update}, that is
-designed for @code{@@include} files.@refill

-should not even include indices, which should be listed in an included
-file of their own.@refill

-Moreover, each of the included files must contain exactly one highest

-and this node must be the first node in the included file.
-Furthermore, each of these highest level nodes in each included file
-must be at the same hierarchical level in the file structure.
-Usually, each is an @code{@@chapter}, an @code{@@appendix}, or an
-@code{@@unnumbered} node. Thus, normally, each included file contains
-one, and only one, chapter or equivalent-level node.@refill

-
-When Info was first created, it was customary to create many small
-Info files on one subject. Each Info file was formatted from its own
-Texinfo source file. This custom meant that Emacs did not need to
-make a large buffer to hold the whole of a large Info file when
-someone wanted information; instead, Emacs allocated just enough
-memory for the small Info file that contained the particular
-information sought. This way, Emacs could avoid wasting memory.@refill
-
-References from one file to another were made by referring to the file
-name as well as the node name. (@xref{Other Info Files, , Referring to
-Other Info Files}. Also, see @ref{Four and Five Arguments, ,
-@code{@@xref} with Four and Five Arguments}.)@refill
-
-Include files were designed primarily as a way to create a single,
-large printed manual out of several smaller Info files. In a printed
-manual, all the references were within the same document, so @TeX{}
-could automatically determine the references' page numbers. The Info
-formatting commands used include files only for creating joint
-indices; each of the individual Texinfo files had to be formatted for
-Info individually. (Each, therefore, required its own
-@code{@@setfilename} line.)@refill
-
-However, because large Info files are now split automatically, it is
-no longer necessary to keep them small.@refill
-
-Nowadays, multiple Texinfo files are used mostly for large documents,
-such as @cite{The GNU Emacs Lisp Reference Manual}, and for projects
-in which several different people write different sections of a
-document simultaneously.@refill
-
-In addition, the Info formatting commands have been extended to work
-with the @code{@@include} command so as to create a single large Info
-file that is split into smaller files if necessary. This means that
-you can write menus and cross references without naming the different
-Texinfo files.@refill

-When you open a book, the right-hand page is odd-numbered, and

-left blank if necessary. Reports, however, are often printed on just
-one side of paper, and chapters begin on a fresh page immediately
-following the end of the preceding chapter. In short or informal
-reports, chapters often do not begin on a new page at all, but are
-separated from the preceding text by a small amount of whitespace.@refill

-The @code{@@setchapternewpage} command controls whether chapters begin
-on new pages, and whether one of the standard heading formats is used.
-In addition, Texinfo has several heading and footing commands that you

-
-In Texinfo, headings and footings are single lines at the tops and

-The standard format for two-sided printing depends on whether the page
-number is even or odd. By convention, even-numbered pages are on the
-left- and odd-numbered pages are on the right. (@TeX{} will adjust the
-widths of the left- and right-hand margins. Usually, widths are
-correct, but during double-sided printing, it is wise to check that

-odd-numbered pages.)@refill

-In the standard double-sided format, the left part of the left-hand
-(even-numbered) page contains the page number, the central part is

-@noindent
-In this case, @code{texinfo-format-region} detects the missing closing

-Sometimes @code{texinfo-format-region} fails to detect mistakes. For

-
-@example

-This is because Info perceives the example of the error as the first

-@samp{@@par} is an internal @TeX{} command of no relevance to Texinfo.
-@samp{l.27} means that @TeX{} detected the problem on line 27 of the

-circumstance.@refill
-
-Unfortunately, @TeX{} is not always so helpful, and sometimes you must

-
-In any case, if you run into a problem like this, you can do one of three

-@enumerate
-@item
-You can tell @TeX{} to continue running and ignore just this error by

-
-@item
-You can tell @TeX{} to continue running and to ignore all errors as best
-it can by typing @kbd{r @key{RET}} at the @samp{?} prompt.@refill
-
-This is often the best thing to do. However, beware: the one error
-may produce a cascade of additional error messages as its consequences
-are felt through the rest of the file. To stop @TeX{} when it is
-producing such an avalanche of error messages, type @kbd{C-c} (or
-@kbd{C-c C-c}, if you are running a shell inside Emacs).
-
-@item
-You can tell @TeX{} to stop this run by typing @kbd{x @key{RET}}
-at the @samp{?} prompt.@refill
-@end enumerate
-
-Please note that if you are running @TeX{} inside Emacs, you need to
-switch to the shell buffer and line at which @TeX{} offers the @samp{?}
-prompt.@refill
-
-Sometimes @TeX{} will format a file without producing error messages even
-though there is a problem. This usually occurs if a command is not ended
-but @TeX{} is able to continue processing anyhow. For example, if you fail
-to end an itemized list with the @code{@@end itemize} command, @TeX{} will
-write a DVI file that you can print out. The only error message that
-@TeX{} will give you is the somewhat mysterious comment that@refill
-
-@example
-(@@end occurred inside a group at level 1)
-@end example
-
-@noindent
-However, if you print the DVI file, you will find that the text
-of the file that follows the itemized list is entirely indented as if
-it were part of the last item in the itemized list. The error message
-is the way @TeX{} says that it expected to find an @code{@@end}
-command somewhere in the file; but that it could not determine where
-it was needed.@refill
-
-Another source of notoriously hard-to-find errors is a missing
-@code{@@end group} command. If you ever are stumped by
-incomprehensible errors, look for a missing @code{@@end group} command
-first.@refill
-
-If the Texinfo file lacks header lines,

-@emph{after} all the other processing has been done. For this reason,
-you can not use @code{@@refill} with a paragraph containing either
-@code{@@*} or @code{@@w@{ @dots{} @}} since the refilling action will
-override those two commands.@refill
-
-The @code{texinfo-format-region} and @code{texinfo-format-buffer}
-commands now automatically append @code{@@refill} to the end of each
-paragraph that should be filled. They do not append @code{@@refill} to
-the ends of paragraphs that contain @code{@@*} or @w{@code{@@w@{ @dots{}@}}}
-and therefore do not refill or indent them.@refill

-@appendix @@-Command Syntax
-@cindex @@-command syntax
-
-The character @samp{@@} is used to start special Texinfo commands.
-(It has the same meaning that @samp{\} has in plain @TeX{}.) Texinfo
-has four types of @@-command:@refill
-
-@table @asis
-@item 1. Non-alphabetic commands.
-These commands consist of an @@ followed by a punctuation mark or other
-character that is not part of the alphabet. Non-alphabetic commands are
-almost always part of the text within a paragraph, and never take any
-argument. The two characters (@@ and the other one) are complete in
-themselves; none is followed by braces. The non-alphabetic commands
-are: @code{@@.}, @code{@@:}, @code{@@*}, @code{@@@kbd{SPACE}},
-@code{@@@kbd{TAB}}, @code{@@@kbd{NL}}, @code{@@@@}, @code{@@@{}, and
-@code{@@@}}.@refill
-
-@item 2. Alphabetic commands that do not require arguments.
-These commands start with @@ followed by a word followed by left- and
-right-hand braces. These commands insert special symbols in the
-document; they do not require arguments. For example,
-@code{@@dots@{@}} @result{} @samp{@dots{}}, @code{@@equiv@{@}}
-@result{} @samp{@equiv{}}, @code{@@TeX@{@}} @result{} `@TeX{}',
-and @code{@@bullet@{@}} @result{} @samp{@bullet{}}.@refill
-
-@item 3. Alphabetic commands that require arguments within braces.
-These commands start with @@ followed by a letter or a word, followed by an
-argument within braces. For example, the command @code{@@dfn} indicates
-the introductory or defining use of a term; it is used as follows: @samp{In
-Texinfo, @@@@-commands are @@dfn@{mark-up@} commands.}@refill
-
-@item 4. Alphabetic commands that occupy an entire line.
-These commands occupy an entire line. The line starts with @@,
-followed by the name of the command (a word); for example, @code{@@center}
-or @code{@@cindex}. If no argument is needed, the word is followed by
-the end of the line. If there is an argument, it is separated from
-the command name by a space. Braces are not used.@refill
-@end table
-
-@cindex Braces and argument syntax
-Thus, the alphabetic commands fall into classes that have
-different argument syntaxes. You cannot tell to which class a command
-belongs by the appearance of its name, but you can tell by the
-command's meaning: if the command stands for a glyph, it is in
-class 2 and does not require an argument; if it makes sense to use the
-command together with other text as part of a paragraph, the command
-is in class 3 and must be followed by an argument in braces;
-otherwise, it is in class 4 and uses the rest of the line as its
-argument.@refill
-
-The purpose of having a different syntax for commands of classes 3 and
-4 is to make Texinfo files easier to read, and also to help the GNU
-Emacs paragraph and filling commands work properly. There is only one
-exception to this rule: the command @code{@@refill}, which is always
-used at the end of a paragraph immediately following the final period
-or other punctuation character. @code{@@refill} takes no argument and
-does @emph{not} require braces. @code{@@refill} never confuses the
-Emacs paragraph commands because it cannot appear at the beginning of
-a line.@refill

-
-Version 2.11, Sat Apr 1 09:15:21 1995
-
-Changes since 2.7 beta:
-
-Although the basic code remains the same, there are numerous nits
-fixed, including some display bugs, and a memory leak. Some changes
-that have taken place with larger impact include the way in which the
-(dir) node is built; I have added in support for "localdir"
-directories among other things. Info files may be stored in
-compressed formats, and in their own subdirectories; menu items which
-do not explicitly name the node to which they are attached have the
-menu item name looked up as an Info file if it is not found within the
-current document. This means that the menu item:
-
-* Info:: The Info documentation reader.
-
-in (dir) refers to the info node "(info)Top".
-
-Please see the ChangeLog and documentation for details on other
-changes.

-
-Changes since 2.5 beta:
-
-Note that versions 2.6 and 2.7 Beta were only released to a select group.
-
-* "info-" removed from the front of M-x commands.
-
-* Automatic footnote display. When you enter a node which contains
- footnotes, and the variable "automatic-footnotes" is "On", Info pops
- up a window containing the footnotes. Likewise, when you leave that
- node, the window containing the footnotes goes away.
-
-* Cleaner built in documentation, and documentation functions.
-
- Use:
- o `M-x describe-variable' to read a variable's documenation
- o `M-x describe-key' to find out what a particular keystroke does.
- o `M-x describe-function' to read a function's documentation.
- o `M-x where-is' to find out what keys invoke a particular function.
-
-* Info can "tile" the displayed windows (via "M-x tile-windows"). If
- the variable "automatic-tiling" is "On", then splitting a window or
- deleting a window causes the remaining windows to be retiled.
-
-* You can save every keystroke you type in a "dribble file" by using the
- `--dribble FILENAME' option. You can initially read keystrokes from an
- alternate input stream with `--restore FILENAME', or by redirecting
- input on the command line `info < old-dribble'.
-
-* New behaviour of menu items. If the label is the same as the
- target node name, and the node couldn't be found in the current file,
- treat the label as a file name. For example, a menu entry in "DIR"
- might contain:
-
- * Emacs:: Cool text-editor.
-
- Info would not find the node "(dir)Emacs", so just plain "(emacs)"
- would be tried.
-
-* New variable "ISO-Latin" allows you to use European machines with
- 8-bit character sets.
-
-* Cleanups in echo area reading, and redisplay. Cleanups in handling the
- window which shows possible completions.
-
-* Info can now read files that have been compressed. An array in filesys.c
- maps extensions to programs that can decompress stdin, and write the results
- to stdout. Currently, ".Z"/uncompress, ".z"/gunzip, and ".Y"/unyabba are
- supported. The modeline for a compressed file shows "zz" in it.
-
-* There is a new variable "gc-compressed-files" which, if non-zero, says
- it is okay to reclaim the file buffer space allocated to a file which
- was compressed, if, and only if, that file's contents do not appear in
- any history node.
-
-* New file `nodemenu.c' implements a few functions for manipulating
- previously visited nodes. `C-x C-b' (list-visited-nodes) produces a
- menu of the nodes that could be reached by info-history-node in some
- window. `C-x b' (select-visited-node) is similar, but reads one of
- the node names with completion.
-
-* Keystroke `M-r' (move_to_screen_line) allows the user to place the cursor at
- the start of a specific screen line. Without a numeric argument, place the
- cursor on the center line; with an arg, place the cursor on that line.
-
-* Interruptible display implemented. Basic display speedups and hacks.
-* The message "*** Tags Out of Date ***" now means what it says.
-* Index searching with `,' (info-index-next) has been improved.
-* When scrolling with C-v, C-M-v, or M-v, only "Page Only" scrolling
- will happen.
-
-* Continous scrolling (along with `]' (info-global-next) and `['
- (info-global-prev) works better. `]' and `[' accept numeric
- arguments, moving that many nodes in that case.
-
-* `C-x w' (info-toggle-wrap) controls how lines wider than the width
- of the screen are displayed. If a line is too long, a `$' is
- displayed in the rightmost column of the window.
-
-* There are some new variables for controlling the behaviour of Info
- interactively. The current list of variables is as follows:
-
- Variable Name Default Value Description
- ------------- ------------- -----------
- `automatic-footnotes' On When "On", footnotes appear and
- disappear automatically.
-
- `automatic-tiling' Off When "On", creating of deleting a
- window resizes other windows.
-
- `visible-bell' Off If non-zero, try to use a visible bell.
-
- `errors-ring-bell' On If non-zero, errors cause a ring.
-
- `show-index-match' On If non-zero, the portion of the string
- matched is highlighted by changing its
- case.
-
- `scroll-behaviour' Continuous One of "Continuous", "Next Only", or
- "Page Only". "Page Only" prevents you from
- scrolling past the bottom or top of a node.
- "Next Only" causes the Next or Prev node to
- be selected when you scroll past the bottom
- or top of a node. "Continous" moves
- linearly through the files hierchichal
- structure.
-
- `scroll-step' 0 Controls how scrolling is done for you when
- the cursor moves out of the current window.
- Non-zero means it is the number of lines
- you would like the screen to shift. A
- value of 0 means to center the line
- containing the cursor in the window.
-
- `gc-compressed-files' Off If non-zero means it is okay to reclaim the
- file buffer space allocated to a file which
- was compressed, if, and only if, that
- file's contents do not appear in the node
- list of any window.
-
- `ISO-Latin' Off Non-zero means that you are using an ISO
- Latin character set. By default, standard
- ASCII characters are assumed.
-________________________________________
-This release of Info is version 2.5 beta.
-
-Changes since 2.4 beta:
-
-* Index (i) and (,) commands fully implemented.
-* "configure" script now shipped with Info.
-* New function "set-variable" allows users to set various variables.
-* User-settable behaviour on end or beginning of node scrolling. This
- supercedes the SPC and DEL changes in 2.3 beta.
-
-________________________________________
-This release of Info is version 2.4 beta.
-
-Changes since 2.3 beta:
-
-* info-last-node now means move to the last node of this info file.
-* info-history-node means move backwards through this window's node history.
-* info-first-node moves to the first node in the Info file. This node is
- not necessarily "Top"!
-* SPC and DEL can select the Next or Prev node after printing an informative
- message when pressed at the end/beg of a node.
-
-----------------------------------------
-This release of Info is version 2.3 beta.
-
-Changes since 2.2 beta:
-
-* M-x command lines if NAMED_COMMANDS is #defined. Variable in Makefile.
-* Screen height changes made quite robust.
-* Interactive function "set-screen-height" implements user height changes.
-* Scrolling on some terminals is faster now.
-* C-l with numeric arguement is fixed.
-
-----------------------------------------
-This release of Info is version 2.2 beta.
-
-Changes since 2.0:
-
-* C-g can now interrupt multi-file searches.
-* Incremental search is fully implemented.
-* Loading large tag tables is much faster now.
-* makedoc.c replaces shell script, speeding incremental builds.
-* Scrolling in redisplay is implemented.
-* Recursive uses of the echo area made more robust.
-* Garbage collection of unreferenced nodes.

-@end iftex
-
-@dfn{Info} is a program which is used to view Info files on an ASCII
-terminal. @dfn{Info files} are the result of processing Texinfo files
-with the program @code{makeinfo} or with one of the Emacs commands, such
-as @code{M-x texinfo-format-buffer}. Texinfo itself is a documentation
-system that uses a single source file to produce both on-line
-information and printed output. You can typeset and print the
-files that you read in Info.@refill

-@chapter Command Line Options
-@cindex command line options
-@cindex arguments, command line
-
-GNU Info accepts several options to control the initial node being
-viewed, and to specify which directories to search for Info files. Here
-is a template showing an invocation of GNU Info from the shell:
-
-@example
-info [--@var{option-name} @var{option-value}] @var{menu-item}@dots{}
-@end example
-
-The following @var{option-names} are available when invoking Info from
-the shell:
-
-@table @code
-@cindex directory path
-@item --directory @var{directory-path}
-@itemx -d @var{directory-path}
-Add @var{directory-path} to the list of directory paths searched when
-Info needs to find a file. You may issue @code{--directory} multiple
-times; once for each directory which contains Info files.
-Alternatively, you may specify a value for the environment variable
-@code{INFOPATH}; if @code{--directory} is not given, the value of
-@code{INFOPATH} is used. The value of @code{INFOPATH} is a colon
-separated list of directory names. If you do not supply @code{INFOPATH}
-or @code{--directory-path}, Info uses a default path.
-
-@item --file @var{filename}
-@itemx -f @var{filename}
-@cindex Info file, selecting
-Specify a particular Info file to visit. By default, Info visits
-the file @code{dir}; if you use this option, Info will start with
-@code{(@var{filename})Top} as the first file and node.
-
-@item --node @var{nodename}
-@itemx -n @var{nodename}
-@cindex node, selecting
-Specify a particular node to visit in the initial file that Info
-loads. This is especially useful in conjunction with
-@code{--file}@footnote{Of course, you can specify both the file and node
-in a @code{--node} command; but don't forget to escape the open and
-close parentheses from the shell as in: @code{info --node
-"(emacs)Buffers"}}. You may specify @code{--node} multiple times; for
-an interactive Info, each @var{nodename} is visited in its own window,
-for a non-interactive Info (such as when @code{--output} is given) each
-@var{nodename} is processed sequentially.
-
-@item --output @var{filename}
-@itemx -o @var{filename}
-@cindex file, outputting to
-@cindex outputting to a file
-Specify @var{filename} as the name of a file to which to direct output.
-Each node that Info visits will be output to @var{filename} instead of
-interactively viewed. A value of @code{-} for @var{filename} specifies
-the standard output.
-
-@item --subnodes
-@cindex @code{--subnodes}, command line option
-This option only has meaning when given in conjunction with
-@code{--output}. It means to recursively output the nodes appearing in
-the menus of each node being output. Menu items which resolve to
-external Info files are not output, and neither are menu items which are
-members of an index. Each node is only output once.
-
-@item --help
-@itemx -h
-Produces a relatively brief description of the available Info options.
-
-@item --version
-@cindex version information
-Prints the version information of Info and exits.
-
-@item @var{menu-item}
-@cindex menu, following
-Info treats its remaining arguments as the names of menu items. The
-first argument is a menu item in the initial node visited, while
-the second argument is a menu item in the first argument's node.
-You can easily move to the node of your choice by specifying the menu
-names which describe the path to that node. For example,
-
-@example
-info emacs buffers
-@end example
-
-@noindent
-first selects the menu item @samp{Emacs} in the node @samp{(dir)Top},
-and then selects the menu item @samp{Buffers} in the node
-@samp{(emacs)Top}.
-@end table

-@chapter Moving the Cursor
-@cindex cursor, moving
-
-Many people find that reading screens of text page by page is made
-easier when one is able to indicate particular pieces of text with some
-kind of pointing device. Since this is the case, GNU Info (both the
-Emacs and standalone versions) have several commands which allow you to
-move the cursor about the screen. The notation used in this manual to
-describe keystrokes is identical to the notation used within the Emacs
-manual, and the GNU Readline manual. @xref{Characters, , Character
-Conventions, emacs, the GNU Emacs Manual}, if you are unfamiliar with the
-notation.
-
-The following table lists the basic cursor movement commands in Info.
-Each entry consists of the key sequence you should type to execute the
-cursor movement, the @code{M-x}@footnote{@code{M-x} is also a command; it
-invokes @code{execute-extended-command}. @xref{M-x, , Executing an
-extended command, emacs, the GNU Emacs Manual}, for more detailed
-information.} command name (displayed in parentheses), and a short
-description of what the command does. All of the cursor motion commands
-can take an @dfn{numeric} argument (@pxref{Miscellaneous Commands,
-@code{universal-argument}}), to find out how to supply them. With a
-numeric argument, the motion commands are simply executed that
-many times; for example, a numeric argument of 4 given to
-@code{next-line} causes the cursor to move down 4 lines. With a
-negative numeric argument, the motion is reversed; an argument of -4
-given to the @code{next-line} command would cause the cursor to move
-@emph{up} 4 lines.
-
-@table @asis
-@item @code{C-n} (@code{next-line})
-@kindex C-n
-@findex next-line
-Move the cursor down to the next line.
-
-@item @code{C-p} (@code{prev-line})
-@kindex C-p
-@findex prev-line
-Move the cursor up to the previous line.
-
-@item @code{C-a} (@code{beginning-of-line})
-@kindex C-a, in Info windows
-@findex beginning-of-line
-Move the cursor to the start of the current line.
-
-@item @code{C-e} (@code{end-of-line})
-@kindex C-e, in Info windows
-@findex end-of-line
-Move the cursor to the end of the current line.
-
-@item @code{C-f} (@code{forward-char})
-@kindex C-f, in Info windows
-@findex forward-char
-Move the cursor forward a character.

-@chapter Selecting a New Node
-@cindex nodes, selection of
-
-This section details the numerous Info commands which select a new node
-to view in the current window.
-
-The most basic node commands are @samp{n}, @samp{p}, @samp{u}, and
-@samp{l}.
-
-When you are viewing a node, the top line of the node contains some Info
-@dfn{pointers} which describe where the next, previous, and up nodes
-are. Info uses this line to move about the node structure of the file
-when you use the following commands:
-
-@table @asis
-@item @code{n} (@code{next-node})
-@kindex n
-@findex next-node
-Select the `Next' node.
-
-@item @code{p} (@code{prev-node})
-@kindex p
-@findex prev-node
-Select the `Prev' node.
-
-@item @code{u} (@code{up-node})
-@kindex u
-@findex up-node
-Select the `Up' node.
-@end table
-
-You can easily select a node that you have already viewed in this window
-by using the @samp{l} command -- this name stands for "last", and
-actually moves through the list of already visited nodes for this
-window. @samp{l} with a negative numeric argument moves forward through
-the history of nodes for this window, so you can quickly step between
-two adjacent (in viewing history) nodes.
-
-@table @asis
-@item @code{l} (@code{history-node})
-@kindex l
-@findex history-node
-Select the most recently selected node in this window.
-@end table
-
-Two additional commands make it easy to select the most commonly
-selected nodes; they are @samp{t} and @samp{d}.
-
-@table @asis
-@item @code{t} (@code{top-node})
-@kindex t
-@findex top-node
-Select the node @samp{Top} in the current Info file.
-
-@item @code{d} (@code{dir-node})
-@kindex d
-@findex dir-node
-Select the directory node (i.e., the node @samp{(dir)}).
-@end table
-
-Here are some other commands which immediately result in the selection
-of a different node in the current window:
-
-@table @asis
-@item @code{<} (@code{first-node})
-@kindex <
-@findex first-node
-Selects the first node which appears in this file. This node is most
-often @samp{Top}, but it does not have to be.
-
-@item @code{>} (@code{last-node})
-@kindex >
-@findex last-node
-Select the last node which appears in this file.
-
-@item @code{]} (@code{global-next-node})
-@kindex ]
-@findex global-next-node
-Move forward or down through node structure. If the node that you are
-currently viewing has a @samp{Next} pointer, that node is selected.
-Otherwise, if this node has a menu, the first menu item is selected. If
-there is no @samp{Next} and no menu, the same process is tried with the
-@samp{Up} node of this node.
-
-@item @code{[} (@code{global-prev-node})
-@kindex [
-@findex global-prev-node
-Move backward or up through node structure. If the node that you are
-currently viewing has a @samp{Prev} pointer, that node is selected.
-Otherwise, if the node has an @samp{Up} pointer, that node is selected,
-and if it has a menu, the last item in the menu is selected.
-@end table
-
-You can get the same behavior as @code{global-next-node} and
-@code{global-prev-node} while simply scrolling through the file with
-@key{SPC} and @key{DEL}; @xref{Variables, @code{scroll-behavior}}, for
-more information.
-
-@table @asis
-@item @code{g} (@code{goto-node})
-@kindex g
-@findex goto-node
-Read the name of a node and select it. No completion is done while
-reading the node name, since the desired node may reside in a separate
-file. The node must be typed exactly as it appears in the Info file. A
-file name may be included as with any node specification, for example
-
-@example
-@code{g(emacs)Buffers}
-@end example
-
-finds the node @samp{Buffers} in the Info file @file{emacs}.
-
-@item @code{C-x k} (@code{kill-node})
-@kindex C-x k
-@findex kill-node
-Kill a node. The node name is prompted for in the echo area, with a
-default of the current node. @dfn{Killing} a node means that Info tries
-hard to forget about it, removing it from the list of history nodes kept
-for the window where that node is found. Another node is selected in
-the window which contained the killed node.
-
-@item @code{C-x C-f} (@code{view-file})
-@kindex C-x C-f
-@findex view-file
-Read the name of a file and selects the entire file. The command
-@example
-@code{C-x C-f @var{filename}}
-@end example
-is equivalent to typing
-@example
-@code{g(@var{filename})*}
-@end example
-
-@item @code{C-x C-b} (@code{list-visited-nodes})
-@kindex C-x C-b
-@findex list-visited-nodes
-Make a window containing a menu of all of the currently visited nodes.
-This window becomes the selected window, and you may use the standard
-Info commands within it.
-
-@item @code{C-x b} (@code{select-visited-node})
-@kindex C-x b
-@findex select-visited-node
-Select a node which has been previously visited in a visible window.
-This is similar to @samp{C-x C-b} followed by @samp{m}, but no window is
-created.

-@chapter Searching an Info File
-@cindex searching
-
-GNU Info allows you to search for a sequence of characters throughout an
-entire Info file, search through the indices of an Info file, or find
-areas within an Info file which discuss a particular topic.
-
-@table @asis
-@item @code{s} (@code{search})
-@kindex s
-@findex search
-Read a string in the echo area and search for it.
-
-@item @code{C-s} (@code{isearch-forward})
-@kindex C-s
-@findex isearch-forward
-Interactively search forward through the Info file for a string as you
-type it.
-
-@item @code{C-r} (@code{isearch-backward})
-@kindex C-r
-@findex isearch-backward
-Interactively search backward through the Info file for a string as
-you type it.
-
-@item @code{i} (@code{index-search})
-@kindex i
-@findex index-search
-Look up a string in the indices for this Info file, and select a node
-where the found index entry points to.
-
-@item @code{,} (@code{next-index-match})
-@kindex ,
-@findex next-index-match
-Move to the node containing the next matching index item from the last
-@samp{i} command.
-@end table
-
-The most basic searching command is @samp{s} (@code{search}). The
-@samp{s} command prompts you for a string in the echo area, and then
-searches the remainder of the Info file for an occurrence of that string.
-If the string is found, the node containing it is selected, and the
-cursor is left positioned at the start of the found string. Subsequent
-@samp{s} commands show you the default search string within @samp{[} and
-@samp{]}; pressing @key{RET} instead of typing a new string will use the
-default search string.
-
-@dfn{Incremental searching} is similar to basic searching, but the
-string is looked up while you are typing it, instead of waiting until
-the entire search string has been specified.

-@chapter Selecting Cross References
-
-We have already discussed the @samp{Next}, @samp{Prev}, and @samp{Up}
-pointers which appear at the top of a node. In addition to these
-pointers, a node may contain other pointers which refer you to a
-different node, perhaps in another Info file. Such pointers are called
-@dfn{cross references}, or @dfn{xrefs} for short.
-
-@menu
-* Parts of an Xref:: What a cross reference is made of.
-* Selecting Xrefs:: Commands for selecting menu or note items.
-@end menu
-
-@node Parts of an Xref, Selecting Xrefs, , Xref Commands
-@section Parts of an Xref
-
-Cross references have two major parts: the first part is called the
-@dfn{label}; it is the name that you can use to refer to the cross
-reference, and the second is the @dfn{target}; it is the full name of
-the node that the cross reference points to.
-
-The target is separated from the label by a colon @samp{:}; first the
-label appears, and then the target. For example, in the sample menu
-cross reference below, the single colon separates the label from the
-target.
-
-@example
-* Foo Label: Foo Target. More information about Foo.
-@end example
-
-Note the @samp{.} which ends the name of the target. The @samp{.} is
-not part of the target; it serves only to let Info know where the target
-name ends.
-
-A shorthand way of specifying references allows two adjacent colons to
-stand for a target name which is the same as the label name:
-
-@example
-* Foo Commands:: Commands pertaining to Foo.
-@end example
-
-In the above example, the name of the target is the same as the name of
-the label, in this case @code{Foo Commands}.
-
-You will normally see two types of cross reference while viewing nodes:
-@dfn{menu} references, and @dfn{note} references. Menu references
-appear within a node's menu; they begin with a @samp{*} at the beginning
-of a line, and continue with a label, a target, and a comment which
-describes what the contents of the node pointed to contains.
-
-Note references appear within the body of the node text; they begin with
-@code{*Note}, and continue with a label and a target.
-
-Like @samp{Next}, @samp{Prev}, and @samp{Up} pointers, cross references
-can point to any valid node. They are used to refer you to a place
-where more detailed information can be found on a particular subject.
-Here is a cross reference which points to a node within the Texinfo
-documentation: @xref{xref, , Writing an Xref, texinfo, the Texinfo
-Manual}, for more information on creating your own texinfo cross
-references.

-Move the cursor to the start of the next nearest menu item or note
-reference in this node. You can then use @key{RET}
-(@code{select-reference-this-line}) to select the menu or note reference.
-
-@item @code{M-TAB} (@code{move-to-prev-xref})
-@kindex M-TAB, in Info windows
-@findex move-to-prev-xref
-Move the cursor the start of the nearest previous menu item or note

-@chapter Manipulating Multiple Windows
-@cindex windows, manipulating
-
-A @dfn{window} is a place to show the text of a node. Windows have a
-view area where the text of the node is displayed, and an associated
-@dfn{mode line}, which briefly describes the node being viewed.
-
-GNU Info supports multiple windows appearing in a single screen; each
-window is separated from the next by its modeline. At any time, there
-is only one @dfn{active} window, that is, the window in which the cursor
-appears. There are commands available for creating windows, changing
-the size of windows, selecting which window is active, and for deleting
-windows.
-
-@menu
-* The Mode Line:: What appears in the mode line?
-* Basic Windows:: Manipulating windows in Info.
-* The Echo Area:: Used for displaying errors and reading input.
-@end menu
-
-@node The Mode Line, Basic Windows, , Window Commands
-@section The Mode Line
-
-A @dfn{mode line} is a line of inverse video which appears at the bottom
-of an Info window. It describes the contents of the window just above
-it; this information includes the name of the file and node appearing in
-that window, the number of screen lines it takes to display the node,
-and the percentage of text that is above the top of the window. It can
-also tell you if the indirect tags table for this Info file needs to be
-updated, and whether or not the Info file was compressed when stored on
-disk.
-
-Here is a sample mode line for a window containing an uncompressed file
-named @file{dir}, showing the node @samp{Top}.
-
-@example
-@group
------Info: (dir)Top, 40 lines --Top---------------------------------------
- ^^ ^ ^^^ ^^
- (file)Node #lines where
-@end group
-@end example
-
-When a node comes from a file which is compressed on disk, this is
-indicated in the mode line with two small @samp{z}'s. In addition, if
-the Info file containing the node has been split into subfiles, the name
-of the subfile containing the node appears in the modeline as well:
-
-@example
---zz-Info: (emacs)Top, 291 lines --Top-- Subfile: emacs-1.Z---------------
-@end example
-
-When Info makes a node internally, such that there is no corresponding
-info file on disk, the name of the node is surrounded by asterisks
-(@samp{*}). The name itself tells you what the contents of the window
-are; the sample mode line below shows an internally constructed node
-showing possible completions:
-
-@example
------Info: *Completions*, 7 lines --All-----------------------------------
-@end example

-selected if it is already in use, and you have left it temporarily.
-Normally, @samp{C-x o} simply moves the cursor into the next window on
-the screen, or if you are already within the last window, into the first

-Yank back a previous kill, removing the last yanked text first.
-@end table
-
-Sometimes when reading input in the echo area, the command that needed
-input will only accept one of a list of several choices. The choices
-represent the @dfn{possible completions}, and you must respond with one
-of them. Since there are a limited number of responses you can make,
-Info allows you to abbreviate what you type, only typing as much of the
-response as is necessary to uniquely identify it. In addition, you can
-request Info to fill in as much of the response as is possible; this
-is called @dfn{completion}.
-
-The following commands are available when completing in the echo area:
-
-@table @asis
-@item @code{TAB} (@code{echo-area-complete})
-@itemx @code{SPC}
-@kindex TAB, in the echo area
-@kindex SPC, in the echo area
-@findex echo-area-complete
-Insert as much of a completion as is possible.
-
-@item @code{?} (@code{echo-area-possible-completions})
-@kindex ?, in the echo area
-@findex echo-area-possible-completions
-Display a window containing a list of the possible completions of what
-you have typed so far. For example, if the available choices are:
-
-@example
-@group
-bar
-foliate
-food
-forget
-@end group
-@end example
-
-@noindent
-and you have typed an @samp{f}, followed by @samp{?}, the possible
-completions would contain:
-
-@example
-@group
-foliate
-food
-forget
-@end group
-@end example
-
-@noindent
-i.e., all of the choices which begin with @samp{f}. Pressing @key{SPC}
-or @key{TAB} would result in @samp{fo} appearing in the echo area, since
-all of the choices which begin with @samp{f} continue with @samp{o}.
-Now, typing @samp{l} followed by @samp{TAB} results in @samp{foliate}
-appearing in the echo area, since that is the only choice which begins
-with @samp{fol}.
-
-@item @code{ESC C-v} (@code{echo-area-scroll-completions-window})
-@kindex ESC C-v, in the echo area
-@findex echo-area-scroll-completions-window
-Scroll the completions window, if that is visible, or the "other"
-window if not.

-@chapter Printing Out Nodes
-@cindex printing
-
-You may wish to print out the contents of a node as a quick reference
-document for later use. Info provides you with a command for doing
-this. In general, we recommend that you use @TeX{} to format the
-document and print sections of it, by running @code{tex} on the Texinfo
-source file.
-
-@table @asis
-@item @code{M-x print-node}
-@findex print-node
-@cindex INFO_PRINT_COMMAND, environment variable
-Pipe the contents of the current node through the command in the

-@chapter Miscellaneous Commands
-
-GNU Info contains several commands which self-document GNU Info:
-
-@table @asis
-@item @code{M-x describe-command}
-@cindex functions, describing
-@cindex commands, describing
-@findex describe-command
-Read the name of an Info command in the echo area and then display a
-brief description of what that command does.
-
-@item @code{M-x describe-key}
-@cindex keys, describing
-@findex describe-key
-Read a key sequence in the echo area, and then display the name and
-documentation of the Info command that the key sequence invokes.
-
-@item @code{M-x describe-variable}
-Read the name of a variable in the echo area and then display a brief
-description of what the variable affects.
-
-@item @code{M-x where-is}
-@findex where-is
-Read the name of an Info command in the echo area, and then display
-a key sequence which can be typed in order to invoke that command.
-
-@item @code{C-h} (@code{get-help-window})
-@itemx @code{?}
-@kindex C-h
-@kindex ?, in Info windows
-@findex get-help-window
-Create (or Move into) the window displaying @code{*Help*}, and place
-a node containing a quick reference card into it. This window displays
-the most concise information about GNU Info available.
-
-@item @code{h} (@code{get-info-help-node})
-@kindex h
-@findex get-info-help-node
-Try hard to visit the node @code{(info)Help}. The Info file
-@file{info.texi} distributed with GNU Info contains this node. Of
-course, the file must first be processed with @code{makeinfo}, and then
-placed into the location of your Info directory.
-@end table
-
-Here are the commands for creating a numeric argument:
-
-@table @asis
-@item @code{C-u} (@code{universal-argument})
-@cindex numeric arguments
-@kindex C-u
-@findex universal-argument
-Start (or multiply by 4) the current numeric argument. @samp{C-u} is
-a good way to give a small numeric argument to cursor movement or
-scrolling commands; @samp{C-u C-v} scrolls the screen 4 lines, while
-@samp{C-u C-u C-n} moves the cursor down 16 lines.
-
-@item @code{M-1} (@code{add-digit-to-numeric-arg})
-@itemx @code{M-2} @dots{} @code{M-9}
-@kindex M-1 @dots{} M-9
-@findex add-digit-to-numeric-arg
-Add the digit value of the invoking key to the current numeric
-argument. Once Info is reading a numeric argument, you may just type
-the digits of the argument, without the Meta prefix. For example, you
-might give @samp{C-l} a numeric argument of 32 by typing:
-
-@example
-@kbd{C-u 3 2 C-l}
-@end example
-
-@noindent
-or
-
-@example
-@kbd{M-3 2 C-l}
-@end example
-@end table
-
-@samp{C-g} is used to abort the reading of a multi-character key
-sequence, to cancel lengthy operations (such as multi-file searches) and
-to cancel reading input in the echo area.
-
-@table @asis
-@item @code{C-g} (@code{abort-key})
-@cindex cancelling typeahead
-@cindex cancelling the current operation
-@kindex C-g, in Info windows
-@findex abort-key
-Cancel current operation.
-@end table
-
-The @samp{q} command of Info simply quits running Info.
-
-@table @asis
-@item @code{q} (@code{quit})
-@cindex quitting
-@kindex q
-@findex quit
-Exit GNU Info.
-@end table
-
-If the operating system tells GNU Info that the screen is 60 lines tall,
-and it is actually only 40 lines tall, here is a way to tell Info that
-the operating system is correct.
-
-@table @asis
-@item @code{M-x set-screen-height}
-@findex set-screen-height
-@cindex screen, changing the height of
-Read a height value in the echo area and set the height of the
-displayed screen to that value.
-@end table
-
-Finally, Info provides a convenient way to display footnotes which might
-be associated with the current node that you are viewing:
-
-@table @asis
-@item @code{ESC C-f} (@code{show-footnotes})
-@kindex ESC C-f
-@findex show-footnotes
-@cindex footnotes, displaying
-Show the footnotes (if any) associated with the current node in another
-window. You can have Info automatically display the footnotes
-associated with a node when the node is selected by setting the variable
-@code{automatic-footnotes}. @xref{Variables, , @code{automatic-footnotes}}.
-@end table
-
-@node Variables, GNU Info Global Index, Miscellaneous Commands, Top
-@chapter Manipulating Variables
-
-GNU Info contains several @dfn{variables} whose values are looked at by
-various Info commands. You can change the values of these variables,
-and thus change the behavior of Info to more closely match your
-environment and Info file reading manner.
-
-@table @asis
-@item @code{M-x set-variable}
-@cindex variables, setting
-@findex set-variable
-Read the name of a variable, and the value for it, in the echo area and
-then set the variable to that value. Completion is available when
-reading the variable name; often, completion is available when reading
-the value to give to the variable, but that depends on the variable
-itself. If a variable does @emph{not} supply multiple choices to
-complete over, it expects a numeric value.
-
-@item @code{M-x describe-variable}
-@cindex variables, describing
-@findex describe-variable
-Read the name of a variable in the echo area and then display a brief
-description of what the variable affects.
-@end table
-
-Here is a list of the variables that you can set in Info.
-
-@table @code
-@item automatic-footnotes
-@vindex automatic-footnotes
-When set to @code{On}, footnotes appear and disappear automatically.
-This variable is @code{On} by default. When a node is selected, a
-window containing the footnotes which appear in that node is created,
-and the footnotes are displayed within the new window. The window that
-Info creates to contain the footnotes is called @samp{*Footnotes*}. If
-a node is selected which contains no footnotes, and a @samp{*Footnotes*}
-window is on the screen, the @samp{*Footnotes*} window is deleted.
-Footnote windows created in this fashion are not automatically tiled so
-that they can use as little of the display as is possible.
-
-@item automatic-tiling
-@vindex automatic-tiling
-When set to @code{On}, creating or deleting a window resizes other
-windows. This variable is @code{Off} by default. Normally, typing
-@samp{C-x 2} divides the current window into two equal parts. When
-@code{automatic-tiling} is set to @code{On}, all of the windows are
-resized automatically, keeping an equal number of lines visible in each
-window. There are exceptions to the automatic tiling; specifically, the
-windows @samp{*Completions*} and @samp{*Footnotes*} are @emph{not}
-resized through automatic tiling; they remain their original size.
-
-@item visible-bell
-@vindex visible-bell
-When set to @code{On}, GNU Info attempts to flash the screen instead of
-ringing the bell. This variable is @code{Off} by default. Of course,
-Info can only flash the screen if the terminal allows it; in the case
-that the terminal does not allow it, the setting of this variable has no
-effect. However, you can make Info perform quietly by setting the
-@code{errors-ring-bell} variable to @code{Off}.
-
-@item errors-ring-bell
-@vindex errors-ring-bell
-When set to @code{On}, errors cause the bell to ring. The default
-setting of this variable is @code{On}.
-
-@item gc-compressed-files
-@vindex gc-compressed-files
-When set to @code{On}, Info garbage collects files which had to be
-uncompressed. The default value of this variable is @code{Off}.
-Whenever a node is visited in Info, the Info file containing that node
-is read into core, and Info reads information about the tags and nodes
-contained in that file. Once the tags information is read by Info, it
-is never forgotten. However, the actual text of the nodes does not need
-to remain in core unless a particular Info window needs it. For
-non-compressed files, the text of the nodes does not remain in core when
-it is no longer in use. But de-compressing a file can be a time
-consuming operation, and so Info tries hard not to do it twice.
-@code{gc-compressed-files} tells Info it is okay to garbage collect the
-text of the nodes of a file which was compressed on disk.
-
-@item show-index-match
-@vindex show-index-match
-When set to @code{On}, the portion of the matched search string is
-highlighted in the message which explains where the matched search
-string was found. The default value of this variable is @code{On}.
-When Info displays the location where an index match was found,
-(@pxref{Searching Commands, , @code{next-index-match}}), the portion of the
-string that you had typed is highlighted by displaying it in the inverse
-case from its surrounding characters.
-
-@item scroll-behavior
-@vindex scroll-behavior
-Control what happens when forward scrolling is requested at the end of
-a node, or when backward scrolling is requested at the beginning of a
-node. The default value for this variable is @code{Continuous}. There
-are three possible values for this variable:
-
-@table @code
-@item Continuous
-Try to get the first item in this node's menu, or failing that, the
-@samp{Next} node, or failing that, the @samp{Next} of the @samp{Up}.
-This behavior is identical to using the @samp{]}
-(@code{global-next-node}) and @samp{[} (@code{global-prev-node})
-commands.
-
-@item Next Only
-Only try to get the @samp{Next} node.
-
-@item Page Only
-Simply give up, changing nothing. If @code{scroll-behavior} is
-@code{Page Only}, no scrolling command can change the node that is being
-viewed.
-@end table
-
-@item scroll-step
-@vindex scroll-step
-The number of lines to scroll when the cursor moves out of the window.
-Scrolling happens automatically if the cursor has moved out of the
-visible portion of the node text when it is time to display. Usually
-the scrolling is done so as to put the cursor on the center line of the
-current window. However, if the variable @code{scroll-step} has a
-nonzero value, Info attempts to scroll the node text by that many lines;
-if that is enough to bring the cursor back into the window, that is what
-is done. The default value of this variable is 0, thus placing the
-cursor (and the text it is attached to) in the center of the window.
-Setting this variable to 1 causes a kind of "smooth scrolling" which
-some people prefer.
-
-@item ISO-Latin
-@cindex ISO Latin characters
-@vindex ISO-Latin
-When set to @code{On}, Info accepts and displays ISO Latin characters.
-By default, Info assumes an ASCII character set. @code{ISO-Latin} tells
-Info that it is running in an environment where the European standard
-character set is in use, and allows you to input such characters to
-Info, as well as display them.

-.TH info 1 "7th December 1990"
-.SH NAME
-info \- GNU's hypertext system
-.SH SYNOPSIS
-.B info
-[
-.B \-\-option-name option-value
-]
-.B \menu-item...
-.SH COPYRIGHT
-.if n Copyright (C) 1989, 1993 Free Software Foundation, Inc.
-.if t Copyright \(co 1989, 1993 Free Software Foundation, Inc.
-.SH DESCRIPTION
-.LP
-The GNU project has a hypertext system called
-.I Info
-which allows the same source file to be either printed as a
-paper manual, or viewed using
-.B info.
-It is possible to use the
-.B info
-program from inside Emacs, or to use the stand-alone version described here.
-This manual page gives a brief summary of its capabilities.
-
-.SH OPTIONS
-.TP
-.B \-\-directory directory-path
-Add
-.B directory-path
-to the list of directory paths searched when
-.B info
-needs to find a file. You may issue
-.B \-\-directory
-multiple times.
-Alternatively, you may specify a value for the environment variable
-.B INFOPATH;
-if
-.B \-\-directory
-is not given, the value of
-.B INFOPATH
-is used. The value of
-.B INFOPATH
-is a colon separated list of directory names. If you do not supply either
-.B INFOPATH
-or
-.B \-\-directory-path,
-.B info
-uses a default path.
-.TP
-.B \-f filename
-Specify a particular
-.B info
-file to visit. By default,
-.B info
-visits
-the file
-.B dir;
-if you use this option,
-.B info
-will start with
-.B (FILENAME)Top
-as the first file and node.
-.TP
-.B \-n nodename
-Specify a particular node to visit in the initial file that
-.B info
-loads. This is especially useful in conjunction with
-.B \-\-file.
-You may specify
-.B \-\-node
-multiple times.
-.TP
-.B -o file
-Direct output to
-.B file
-instead of starting an interactive
-.B info
-session.
-.TP
-.B \-h
-Produce a relatively brief description of the available
-.B info
-options.
-.TP
-.B \-\-version
-Print the version information of
-.B info
-and exit.
-.TP
-.B menu-item
-.B info
-treats its remaining arguments as the names of menu items.
-The first argument is a menu item in the initial node visited,
-while the second argument is a menu item in the first argument's
-node. You can easily move to the node of your choice by
-specifying the menu names which describe the path to that node.
-For example,
-
-.B info emacs buffers
-
-first selects the menu item
-.B emacs
-in the node
-.B (dir)Top,
-and then selects the menu item
-.B buffers
-in the node
-.B (emacs)Top.
-.SH COMMANDS
-When in
-.B info
-the following commands are available:
-.TP
-.B h
-Invoke the Info tutorial.
-.TP
-.B ?
-Get a short summary of
-.B info
-commands.
-.TP
-.B h
-Select the
-.B info
-node from the main directory; this is much more complete than just
-using
-.B ?.
-.TP
-.B Ctrl-g
-Abort whatever you are doing.
-.TP
-.B Ctrl-l
-Redraw the screen.
-.PP
-Selecting other nodes:
-.TP
-.B n
-Move to the "next" node of this node.
-.TP
-.B p
-Move to the "previous" node of this node.
-.TP
-.B u
-Move to this node's "up" node.
-.TP
-.B m
-Pick a menu item specified by name. Picking a menu item causes another
-node to be selected. You do not need to type a complete nodename; if
-you type a few letters and then a space or tab
-.B info
-will will try to fill in the rest of the nodename. If you ask for further
-completion without typing any more characters you'll be given a list
-of possibilities; you can also get the list with
-.B ?.
-If you type a few characters and then hit return
-.B info
-will try to do a completion, and if it is ambigous use the first possibility.
-.TP
-.B f
-Follow a cross reference. You are asked for the name of the reference,
-using command completion as for
-.B m.
-.TP
-.B l
-Move to the last node you were at.
-.PP
-Moving within a node:
-.TP
-.B Space
-Scroll forward a page.
-.TP
-.B DEL
-Scroll backward a page.
-.TP
-.B b
-Go to the beginning of this node.
-.PP
-Advanced commands:
-.TP
-.B q
-Quit
-.B info.
-.TP
-.B 1
-Pick first item in node's menu.
-.TP
-.B 2 \-\- 5
-Pick second ... fifth item in node's menu.
-.TP
-.B g
-Move to node specified by name. You may include a filename as well,
-as
-.B (FILENAME)NODENAME.
-.TP
-.B s
-Search through this
-.B info
-file for a specified string, and select the node in which
-the next occurrence is found.
-.TP
-.B M-x print-node
-Pipe the contents of the current node through the command in the
-environment variable
-.B INFO_PRINT_COMMAND.
-If the variable does not exist, the node is simply piped to
-.B lpr.
-.SH ENVIRONMENT
-.TP
-.B INFOPATH
-A colon-separated list of directories to search for
-.B info
-files. Used if
-.B \-\-directory
-is not given.
-.TP
-.B INFO_PRINT_COMMAND
-The command used for printing.

-effective, since you must take it on faith that the commands described
-really do what the manual says. By all means go through this manual now
-that you have it; but please try going through the on-line version as
-well.
-
-There are two ways of looking at the online version of this manual:
-
-@enumerate
-@item
-Type @code{info} at your shell's command line. This approach uses a
-small stand-alone program designed just to read Info files.
-
-@item
-Type @code{emacs} at the command line; then type @kbd{C-h i} (Control
-@kbd{h}, followed by @kbd{i}). This approach uses the Info mode of the
-Emacs program, an editor with many other capabilities.
-@end enumerate
-
-In either case, then type @kbd{mInfo} (just the letters), followed by
-@key{RET}---the ``Return'' or ``Enter'' key. At this point, you should
-be ready to follow the instructions in this manual as you read them on
-the screen.
-@c FIXME! (pesch@cygnus.com, 14 dec 1992)
-@c Is it worth worrying about what-if the beginner goes to somebody
-@c else's Emacs session, which already has an Info running in the middle
-@c of something---in which case these simple instructions won't work?

-@comment node-name, next, previous, up
-@section How to use Info
-
-You are talking to the program Info, for reading documentation.
-
- Right now you are looking at one @dfn{Node} of Information.
-A node contains text describing a specific topic at a specific
-level of detail. This node's topic is ``how to use Info''.
-
- The top line of a node is its @dfn{header}. This node's header (look at
-it now) says that it is the node named @samp{Help} in the file
-@file{info}. It says that the @samp{Next} node after this one is the node
-called @samp{Help-P}. An advanced Info command lets you go to any node
-whose name you know.
-
- Besides a @samp{Next}, a node can have a @samp{Previous} or an @samp{Up}.
-This node has a @samp{Previous} but no @samp{Up}, as you can see.
-
- Now it is time to move on to the @samp{Next} node, named @samp{Help-P}.
-
->> Type @samp{n} to move there. Type just one character;
- do not type the quotes and do not type a @key{RET} afterward.
-
-@samp{>>} in the margin means it is really time to try a command.
-
-@node Help-P, Help-^L, Help, Getting Started
-@comment node-name, next, previous, up
-@section Returning to the Previous node
-
-This node is called @samp{Help-P}. The @samp{Previous} node, as you see,
-is @samp{Help}, which is the one you just came from using the @kbd{n}
-command. Another @kbd{n} command now would take you to the next
-node, @samp{Help-^L}.
-
->> But do not do that yet. First, try the @kbd{p} command, which takes
- you to the @samp{Previous} node. When you get there, you can do an
- @kbd{n} again to return here.
-
- This all probably seems insultingly simple so far, but @emph{do not} be
-led into skimming. Things will get more complicated soon. Also,
-do not try a new command until you are told it is time to. Otherwise,
-you may make Info skip past an important warning that was coming up.
-
->> Now do an @kbd{n} to get to the node @samp{Help-^L} and learn more.
-
-@node Help-^L, Help-M, Help-P, Getting Started
-@comment node-name, next, previous, up
-@section The Space, Delete, B and ^L commands.
-
- This node's header tells you that you are now at node @samp{Help-^L}, and
-that @kbd{p} would get you back to @samp{Help-P}. The node's title is
-underlined; it says what the node is about (most nodes have titles).
-
- This is a big node and it does not all fit on your display screen.
-You can tell that there is more that is not visible because you
-can see the string @samp{--Top-----} rather than @samp{--All----} near
-the bottom right corner of the screen.
-
- The Space, Delete and @kbd{B} commands exist to allow you to ``move
-around'' in a node that does not all fit on the screen at once.
-Space moves forward, to show what was below the bottom of the screen.
-Delete moves backward, to show what was above the top of the screen
-(there is not anything above the top until you have typed some spaces).
-
->> Now try typing a Space (afterward, type a Delete to return here).
-
- When you type the space, the two lines that were at the bottom of
-the screen appear at the top, followed by more lines. Delete takes
-the two lines from the top and moves them to the bottom,
-@emph{usually}, but if there are not a full screen's worth of lines
-above them they may not make it all the way to the bottom.
-
- If you type Space when there is no more to see, it rings the
-bell and otherwise does nothing. The same goes for Delete when
-the header of the node is visible.
-
- If your screen is ever garbaged, you can tell Info to print it out
-again by typing @kbd{C-l} (@kbd{Control-L}, that is---hold down ``Control'' and
-type an @key{L} or @kbd{l}).
-
->> Type @kbd{C-l} now.
-
- To move back to the beginning of the node you are on, you can type
-a lot of Deletes. You can also type simply @kbd{b} for beginning.
->> Try that now. (We have put in enough verbiage to push this past
-the first screenful, but screens are so big nowadays that perhaps it
-isn't enough. You may need to shrink your Emacs or Info window.)
-Then come back, with Spaces.
-
- If your screen is very tall, all of this node might fit at once.
-In that case, "b" won't do anything. Sorry; what can we do?
-
- You have just learned a considerable number of commands. If you
-want to use one but have trouble remembering which, you should type
-a @key{?} which prints out a brief list of commands. When you are
-finished looking at the list, make it go away by typing a @key{SPC}.
-
->> Type a @key{?} now. After it finishes, type a @key{SPC}.
-
- (If you are using the standalone Info reader, type `l' to return here.)
-
- From now on, you will encounter large nodes without warning, and
-will be expected to know how to use Space and Delete to move
-around in them without being told. Since not all terminals have
-the same size screen, it would be impossible to warn you anyway.
-
->> Now type @kbd{n} to see the description of the @kbd{m} command.
-
-@node Help-M, Help-Adv, Help-^L, Getting Started
-@comment node-name, next, previous, up
-@section Menus
-
-Menus and the @kbd{m} command
-
- With only the @kbd{n} and @kbd{p} commands for moving between nodes, nodes
-are restricted to a linear sequence. Menus allow a branching
-structure. A menu is a list of other nodes you can move to. It is
-actually just part of the text of the node formatted specially so that
-Info can interpret it. The beginning of a menu is always identified
-by a line which starts with @samp{* Menu:}. A node contains a menu if and
-only if it has a line in it which starts that way. The only menu you
-can use at any moment is the one in the node you are in. To use a
-menu in any other node, you must move to that node first.
-
- After the start of the menu, each line that starts with a @samp{*}
-identifies one subtopic. The line usually contains a brief name
-for the subtopic (followed by a @samp{:}), the name of the node that talks
-about that subtopic, and optionally some further description of the
-subtopic. Lines in the menu that do not start with a @samp{*} have no
-special meaning---they are only for the human reader's benefit and do
-not define additional subtopics. Here is an example:
-
-@example
-* Foo: FOO's Node This tells about FOO
-@end example
-
-The subtopic name is Foo, and the node describing it is @samp{FOO's Node}.
-The rest of the line is just for the reader's Information.
-[[ But this line is not a real menu item, simply because there is
-no line above it which starts with @samp{* Menu:}.]]
-
- When you use a menu to go to another node (in a way that will be
-described soon), what you specify is the subtopic name, the first
-thing in the menu line. Info uses it to find the menu line, extracts
-the node name from it, and goes to that node. The reason that there
-is both a subtopic name and a node name is that the node name must be
-meaningful to the computer and may therefore have to be ugly looking.
-The subtopic name can be chosen just to be convenient for the user to
-specify. Often the node name is convenient for the user to specify
-and so both it and the subtopic name are the same. There is an
-abbreviation for this:
-
-@example
-* Foo:: This tells about FOO
-@end example
-
-@noindent
-This means that the subtopic name and node name are the same; they are
-both @samp{Foo}.
-
->> Now use Spaces to find the menu in this node, then come back to
- the front with a @kbd{b} and some Spaces. As you see, a menu is
- actually visible in its node. If you cannot find a menu in a node
- by looking at it, then the node does not have a menu and the
- @kbd{m} command is not available.
-
- The command to go to one of the subnodes is @kbd{m}---but @emph{do
-not do it yet!} Before you use @kbd{m}, you must understand the
-difference between commands and arguments. So far, you have learned
-several commands that do not need arguments. When you type one, Info
-processes it and is instantly ready for another command. The @kbd{m}
-command is different: it is incomplete without the @dfn{name of the
-subtopic}. Once you have typed @kbd{m}, Info tries to read the
-subtopic name.
-
- Now look for the line containing many dashes near the bottom of the
-screen. There is one more line beneath that one, but usually it is
-blank. If it is empty, Info is ready for a command, such as @kbd{n}
-or @kbd{b} or Space or @kbd{m}. If that line contains text ending
-in a colon, it mean Info is trying to read the @dfn{argument} to a
-command. At such times, commands do not work, because Info tries to
-use them as the argument. You must either type the argument and
-finish the command you started, or type @kbd{Control-g} to cancel the
-command. When you have done one of those things, the line becomes
-blank again.
-
- The command to go to a subnode via a menu is @kbd{m}. After you type
-the @kbd{m}, the line at the bottom of the screen says @samp{Menu item: }.
-You must then type the name of the subtopic you want, and end it with
-a @key{RET}.
-
- You can abbreviate the subtopic name. If the abbreviation is not
-unique, the first matching subtopic is chosen. Some menus put
-the shortest possible abbreviation for each subtopic name in capital
-letters, so you can see how much you need to type. It does not
-matter whether you use upper case or lower case when you type the
-subtopic. You should not put any spaces at the end, or inside of the
-item name, except for one space where a space appears in the item in
-the menu.
-
- You can also use the @dfn{completion} feature to help enter the subtopic
-name. If you type the Tab key after entering part of a name, it will
-magically fill in more of the name---as much as follows uniquely from
-what you have entered.
-
- If you move the cursor to one of the menu subtopic lines, then you do
-not need to type the argument: you just type a Return, and it stands for
-the subtopic of the line you are on.
-
-Here is a menu to give you a chance to practice.
-
-* Menu: The menu starts here.
-
-This menu gives you three ways of going to one place, Help-FOO.
-
-* Foo: Help-FOO. A node you can visit for fun.@*
-* Bar: Help-FOO. Strange! two ways to get to the same place.@*
-* Help-FOO:: And yet another!@*
-
-
->> Now type just an @kbd{m} and see what happens:
-
- Now you are ``inside'' an @kbd{m} command. Commands cannot be used
-now; the next thing you will type must be the name of a subtopic.
-
- You can change your mind about doing the @kbd{m} by typing Control-g.
-
->> Try that now; notice the bottom line clear.
-
->> Then type another @kbd{m}.
-
->> Now type @samp{BAR} item name. Do not type Return yet.
-
- While you are typing the item name, you can use the Delete key to
-cancel one character at a time if you make a mistake.
-
->> Type one to cancel the @samp{R}. You could type another @samp{R} to
- replace it. You do not have to, since @samp{BA} is a valid abbreviation.
-
->> Now you are ready to go. Type a @key{RET}.
-
- After visiting Help-FOO, you should return here.
-
->> Type @kbd{n} to see more commands.
-
-@c If a menu appears at the end of this node, remove it.
-@c It is an accident of the menu updating command.
-
-Here is another way to get to Help-FOO, a menu. You can ignore this
-if you want, or else try it (but then please come back to here).

-@comment node-name, next, previous, up
-@subsection The @kbd{u} command
-
- Congratulations! This is the node @samp{Help-FOO}. Unlike the other
-nodes you have seen, this one has an @samp{Up}: @samp{Help-M}, the node you
-just came from via the @kbd{m} command. This is the usual
-convention---the nodes you reach from a menu have @samp{Up} nodes that lead
-back to the menu. Menus move Down in the tree, and @samp{Up} moves Up.
-@samp{Previous}, on the other hand, is usually used to ``stay on the same
-level but go backwards''
-
- You can go back to the node @samp{Help-M} by typing the command
-@kbd{u} for ``Up''. That puts you at the @emph{front} of the
-node---to get back to where you were reading you have to type
-some @key{SPC}s.
-

-
-@node Help-Adv, Help-Q, Help-M, Getting Started
-@comment node-name, next, previous, up
-@section Some advanced Info commands
-
- The course is almost over, so please stick with it to the end.
-
- If you have been moving around to different nodes and wish to
-retrace your steps, the @kbd{l} command (@kbd{l} for @dfn{last}) will
-do that, one node-step at a time. As you move from node to node, Info
-records the nodes where you have been in a special history list. The
-@kbd{l} command revisits nodes in the history list; each successive
-@kbd{l} command moves one step back through the history.
-
- If you have been following directions, ad @kbd{l} command now will get
-you back to @samp{Help-M}. Another @kbd{l} command would undo the
-@kbd{u} and get you back to @samp{Help-FOO}. Another @kbd{l} would undo
-the @kbd{m} and get you back to @samp{Help-M}.
-
->> Try typing three @kbd{l}'s, pausing in between to see what each
- @kbd{l} does.
-
-Then follow directions again and you will end up back here.
-
- Note the difference between @kbd{l} and @kbd{p}: @kbd{l} moves to
-where @emph{you} last were, whereas @kbd{p} always moves to the node
-which the header says is the @samp{Previous} node (from this node, to
-@samp{Help-M}).
-
- The @samp{d} command gets you instantly to the Directory node.
-This node, which is the first one you saw when you entered Info,
-has a menu which leads (directly, or indirectly through other menus),
-to all the nodes that exist.
-
->> Try doing a @samp{d}, then do an @kbd{l} to return here (yes,
- @emph{do} return).
-
- Sometimes, in Info documentation, you will see a cross reference.
-Cross references look like this: @xref{Help-Cross, Cross}. That is a
-real, live cross reference which is named @samp{Cross} and points at
-the node named @samp{Help-Cross}.
-
- If you wish to follow a cross reference, you must use the @samp{f}
-command. The @samp{f} must be followed by the cross reference name
-(in this case, @samp{Cross}). While you enter the name, you can use the
-Delete key to edit your input. If you change your mind about following
-any reference, you can use @kbd{Control-g} to cancel the command.
-
- Completion is available in the @samp{f} command; you can complete among
-all the cross reference names in the current node by typing a Tab.
-
->> Type @samp{f}, followed by @samp{Cross}, and a @key{RET}.
-
- To get a list of all the cross references in the current node, you can
-type @kbd{?} after an @samp{f}. The @samp{f} continues to await a
-cross reference name even after printing the list, so if you don't
-actually want to follow a reference, you should type a @kbd{Control-g}
-to cancel the @samp{f}.
-
->> Type "f?" to get a list of the cross references in this node. Then
- type a @kbd{Control-g} and see how the @samp{f} gives up.

-
-@kbd{g}, @kbd{s}, @kbd{1}, -- @kbd{9}, and @kbd{e}
-
-If you know a node's name, you can go there by typing @kbd{g}, the
-name, and @key{RET}. Thus, @kbd{gTop@key{RET}} would go to the node
-called @samp{Top} in this file (its directory node).
-@kbd{gExpert@key{RET}} would come back here.
-
-Unlike @kbd{m}, @kbd{g} does not allow the use of abbreviations.
-
-To go to a node in another file, you can include the filename in the
-node name by putting it at the front, in parentheses. Thus,
-@kbd{g(dir)Top@key{RET}} would go to the Info Directory node, which is
-node @samp{Top} in the file @file{dir}.
-
-The node name @samp{*} specifies the whole file. So you can look at
-all of the current file by typing @kbd{g*@key{RET}} or all of any
-other file with @kbd{g(FILENAME)@key{RET}}.
-
-The @kbd{s} command allows you to search a whole file for a string.
-It switches to the next node if and when that is necessary. You
-type @kbd{s} followed by the string to search for, terminated by
-@key{RET}. To search for the same string again, just @kbd{s} followed
-by @key{RET} will do. The file's nodes are scanned in the order
-they are in in the file, which has no necessary relationship to the
-order that they may be in in the tree structure of menus and @samp{next} pointers.
-But normally the two orders are not very different. In any case,
-you can always do a @kbd{b} to find out what node you have reached, if
-the header is not visible (this can happen, because @kbd{s} puts your
-cursor at the occurrence of the string, not at the beginning of the
-node).
-
-If you grudge the system each character of type-in it requires, you
-might like to use the commands @kbd{1}, @kbd{2}, @kbd{3}, @kbd{4}, ...
-@kbd{9}. They are short for the @kbd{m} command together with an
-argument. @kbd{1} goes through the first item in the current node's
-menu; @kbd{2} goes through the second item, etc.
-
-If you display supports multiple fonts, and you are using Emacs' Info
-mode to read Info files, the @samp{*} for the fifth menu item is
-underlines, and so is the @samp{*} for the ninth item; these underlines
-make it easy to see at a glance which number to use for an item.
-
-On ordinary terminals, you won't have underlining. If you need to
-actually count items, it is better to use @kbd{m} instead, and specify
-the name.
-
-The Info command @kbd{e} changes from Info mode to an ordinary
-Emacs editing mode, so that you can edit the text of the current node.
-Type @kbd{C-c C-c} to switch back to Info. The @kbd{e} command is allowed
-only if the variable @code{Info-enable-edit} is non-@code{nil}.
-
-@node Add, Menus, Expert, Advanced Info

-@section Adding a new node to Info
-
-To add a new topic to the list in the Info directory, you must:
-@enumerate
-@item
-Create some nodes, in some file, to document that topic.
-@item
-Put that topic in the menu in the directory. @xref{Menus, Menu}.
-@end enumerate
-
-Usually, the way to create the nodes is with Texinfo @pxref{Top,, Overview of
-Texinfo, texinfo, Texinfo: The GNU Documentation Format}); this has the
-advantage that you can also make a printed manual from them. However,
-if hyou want to edit an Info file, here is how.
-
- The new node can live in an existing documentation file, or in a new
-one. It must have a @key{^_} character before it (invisible to the
-user; this node has one but you cannot see it), and it ends with either
-a @key{^_}, a @key{^L}, or the end of file. Note: If you put in a
-@key{^L} to end a new node, be sure that there is a @key{^_} after it
-to start the next one, since @key{^L} cannot @emph{start} a node.
-Also, a nicer way to make a node boundary be a page boundary as well
-is to put a @key{^L} @emph{right after} the @key{^_}.
-
- The @key{^_} starting a node must be followed by a newline or a
-@key{^L} newline, after which comes the node's header line. The
-header line must give the node's name (by which Info finds it),
-and state the names of the @samp{Next}, @samp{Previous}, and @samp{Up} nodes (if
-there are any). As you can see, this node's @samp{Up} node is the node
-@samp{Top}, which points at all the documentation for Info. The @samp{Next}
-node is @samp{Menus}.
-
- The keywords @dfn{Node}, @dfn{Previous}, @dfn{Up}, and @dfn{Next},
-may appear in any order, anywhere in the header line, but the
-recommended order is the one in this sentence. Each keyword must be
-followed by a colon, spaces and tabs, and then the appropriate name.
-The name may be terminated with a tab, a comma, or a newline. A space
-does not end it; node names may contain spaces. The case of letters
-in the names is insignificant.
-
- A node name has two forms. A node in the current file is named by
-what appears after the @samp{Node: } in that node's first line. For
-example, this node's name is @samp{Add}. A node in another file is
-named by @samp{(@var{filename})@var{node-within-file}}, as in
-@samp{(info)Add} for this node. If the file name starts with ``./'',
-then it is relative to the current directory; otherwise, it is relative
-starting from the standard Info file directory of your site.
-The name @samp{(@var{filename})Top} can be abbreviated to just
-@samp{(@var{filename})}. By convention, the name @samp{Top} is used for
-the ``highest'' node in any single file---the node whose @samp{Up} points
-out of the file. The Directory node is @file{(dir)}. The @samp{Top} node
-of a document file listed in the Directory should have an @samp{Up:
-(dir)} in it.
-
- The node name @kbd{*} is special: it refers to the entire file.
-Thus, @kbd{g*} shows you the whole current file. The use of the
-node @kbd{*} is to make it possible to make old-fashioned,
-unstructured files into nodes of the tree.
-
- The @samp{Node:} name, in which a node states its own name, must not
-contain a filename, since Info when searching for a node does not
-expect one to be there. The @samp{Next}, @samp{Previous} and @samp{Up} names may
-contain them. In this node, since the @samp{Up} node is in the same file,
-it was not necessary to use one.
-
- Note that the nodes in this file have a file name in the header
-line. The file names are ignored by Info, but they serve as comments
-to help identify the node for the user.
-
-@node Menus, Cross-refs, Add, Advanced Info
-@comment node-name, next, previous, up
-@section How to Create Menus
-
- Any node in the Info hierarchy may have a @dfn{menu}---a list of subnodes.
-The @kbd{m} command searches the current node's menu for the topic which it
-reads from the terminal.
-
- A menu begins with a line starting with @samp{* Menu:}. The rest of the
-line is a comment. After the starting line, every line that begins
-with a @samp{* } lists a single topic. The name of the topic--the
-argument that the user must give to the @kbd{m} command to select this
-topic---comes right after the star and space, and is followed by a
-colon, spaces and tabs, and the name of the node which discusses that
-topic. The node name, like node names following @samp{Next}, @samp{Previous}
-and @samp{Up}, may be terminated with a tab, comma, or newline; it may also
-be terminated with a period.
-
- If the node name and topic name are the same, then rather than
-giving the name twice, the abbreviation @samp{* NAME::} may be used
-(and should be used, whenever possible, as it reduces the visual
-clutter in the menu).
-
- It is considerate to choose the topic names so that they differ
-from each other very near the beginning---this allows the user to type
-short abbreviations. In a long menu, it is a good idea to capitalize
-the beginning of each item name which is the minimum acceptable
-abbreviation for it (a long menu is more than 5 or so entries).
-
- The nodes listed in a node's menu are called its ``subnodes'', and
-it is their ``superior''. They should each have an @samp{Up:} pointing at
-the superior. It is often useful to arrange all or most of the
-subnodes in a sequence of @samp{Next} and @samp{Previous} pointers so that someone who
-wants to see them all need not keep revisiting the Menu.
-
- The Info Directory is simply the menu of the node @samp{(dir)Top}---that
-is, node @samp{Top} in file @file{.../info/dir}. You can put new entries
-in that menu just like any other menu. The Info Directory is @emph{not} the
-same as the file directory called @file{info}. It happens that many of
-Info's files live on that file directory, but they do not have to; and
-files on that directory are not automatically listed in the Info
-Directory node.
-
- Also, although the Info node graph is claimed to be a ``hierarchy'',
-in fact it can be @emph{any} directed graph. Shared structures and
-pointer cycles are perfectly possible, and can be used if they are
-appropriate to the meaning to be expressed. There is no need for all
-the nodes in a file to form a connected structure. In fact, this file
-has two connected components. You are in one of them, which is under
-the node @samp{Top}; the other contains the node @samp{Help} which the
-@kbd{h} command goes to. In fact, since there is no garbage
-collector, nothing terrible happens if a substructure is not pointed
-to, but such a substructure is rather useless since nobody can
-ever find out that it exists.
-
-@node Cross-refs, Tags, Menus, Advanced Info
-@comment node-name, next, previous, up
-@section Creating Cross References
-
- A cross reference can be placed anywhere in the text, unlike a menu
-item which must go at the front of a line. A cross reference looks
-like a menu item except that it has @samp{*note} instead of @kbd{*}.
-It @emph{cannot} be terminated by a @samp{)}, because @samp{)}'s are
-so often part of node names. If you wish to enclose a cross reference
-in parentheses, terminate it with a period first. Here are two
-examples of cross references pointers:
-
-@example
-*Note details: commands. (See *note 3: Full Proof.)
-@end example
-
-They are just examples. The places they ``lead to'' do not really exist!
-
-@node Tags, Checking, Cross-refs, Advanced Info
-@comment node-name, next, previous, up
-@section Tag Tables for Info Files
-
- You can speed up the access to nodes of a large Info file by giving
-it a tag table. Unlike the tag table for a program, the tag table for
-an Info file lives inside the file itself and is used
-automatically whenever Info reads in the file.
-
- To make a tag table, go to a node in the file using Emacs Info mode and type
-@kbd{M-x Info-tagify}. Then you must use @kbd{C-x C-s} to save the
-file.
-
- Once the Info file has a tag table, you must make certain it is up
-to date. If, as a result of deletion of text, any node moves back
-more than a thousand characters in the file from the position
-recorded in the tag table, Info will no longer be able to find that
-node. To update the tag table, use the @code{Info-tagify} command again.
-
- An Info file tag table appears at the end of the file and looks like
-this:
-
-@example
-^_
-Tag Table:
-File: info, Node: Cross-refs^?21419
-File: info, Node: Tags^?22145
-^_
-End Tag Table
-@end example
-
-@noindent
-Note that it contains one line per node, and this line contains
-the beginning of the node's header (ending just after the node name),
-a Delete character, and the character position in the file of the
-beginning of the node.
-
-@node Checking, Emacs Info Variables, Tags, Advanced Info
-@comment node-name, next, previous, up
-@section Checking an Info File
-
- When creating an Info file, it is easy to forget the name of a node
-when you are making a pointer to it from another node. If you put in
-the wrong name for a node, this is not detected until someone
-tries to go through the pointer using Info. Verification of the Info
-file is an automatic process which checks all pointers to nodes and
-reports any pointers which are invalid. Every @samp{Next}, @samp{Previous}, and
-@samp{Up} is checked, as is every menu item and every cross reference. In
-addition, any @samp{Next} which does not have a @samp{Previous} pointing back is
-reported. Only pointers within the file are checked, because checking
-pointers to other files would be terribly slow. But those are usually
-few.
-
- To check an Info file, do @kbd{M-x Info-validate} while looking at
-any node of the file with Emacs Info mode.
-
-@node Emacs Info Variables, , Checking, Advanced Info

-@chapter Command Line Options
-@cindex command line options
-@cindex arguments, command line
-
-GNU Info accepts several options to control the initial node being
-viewed, and to specify which directories to search for info files. Here
-is a template showing an invocation of GNU Info from the shell:
-
-@example
-info [--@var{option-name} @var{option-value}] @var{menu-item}@dots{}
-@end example
-
-The following @var{option-names} are available when invoking Info from
-the shell:
-
-@table @code
-@cindex directory path
-@item --directory @var{directory-path}
-@itemx -d @var{directory-path}
-Adds @var{directory-path} to the list of directory paths searched when
-Info needs to find a file. You may issue @code{--directory} multiple
-times; once for each directory which contains info files.
-Alternatively, you may specify a value for the environment variable
-@code{INFOPATH}; if @code{--directory} is not given, the value of
-@code{INFOPATH} is used. The value of @code{INFOPATH} is a colon
-separated list of directory names. If you do not supply
-@code{INFOPATH} or @code{--directory-path} a default path is used.
-
-@item --file @var{filename}
-@itemx -f @var{filename}
-@cindex info file, selecting
-Specifies a particular info file to visit. Instead of visiting the file
-@code{dir}, Info will start with @code{(@var{filename})Top} as the first
-file and node.
-
-@item --node @var{nodename}
-@itemx -n @var{nodename}
-@cindex node, selecting
-Specifies a particular node to visit in the initial file loaded. This
-is especially useful in conjunction with @code{--file}@footnote{Of
-course, you can specify both the file and node in a @code{--node}
-command; but don't forget to escape the open and close parentheses from
-the shell as in: @code{info --node '(emacs)Buffers'}}. You may specify
-@code{--node} multiple times; for an interactive Info, each
-@var{nodename} is visited in its own window, for a non-interactive Info
-(such as when @code{--output} is given) each @var{nodename} is processed
-sequentially.
-
-@item --output @var{filename}
-@itemx -o @var{filename}
-@cindex file, outputting to
-@cindex outputting to a file
-Specify @var{filename} as the name of a file to output to. Each node
-that Info visits will be output to @var{filename} instead of
-interactively viewed. A value of @code{-} for @var{filename} specifies
-the standard output.
-
-@item --subnodes
-@cindex @code{--subnodes}, command line option
-This option only has meaning when given in conjunction with
-@code{--output}. It means to recursively output the nodes appearing in
-the menus of each node being output. Menu items which resolve to
-external info files are not output, and neither are menu items which are
-members of an index. Each node is only output once.
-
-@item --help

-names which describe the path to that node. For example,
-
-@example
-info emacs buffers
-@end example
-
-first selects the menu item @samp{Emacs} in the node @samp{(dir)Top},

-@node Cursor Commands
-@chapter Moving the Cursor
-@cindex cursor, moving
-Many people find that reading screens of text page by page is made
-easier when one is able to indicate particular pieces of text with some
-kind of pointing device. Since this is the case, GNU Info (both the
-Emacs and standalone versions) have several commands which allow you to
-move the cursor about the screen. The notation used in this manual to
-describe keystrokes is identical to the notation used within the Emacs
-manual, and the GNU Readline manual. @xref{Characters, , Character
-Conventions, emacs, the GNU Emacs Manual}, if you are unfamilar with the
-notation.
-
-The following table lists the basic cursor movement commands in Info.
-Each entry consists of the key sequence you should type to execute the
-cursor movement, the @code{M-x}@footnote{@code{M-x} is also a command; it
-invokes @code{execute-extended-command}. @xref{M-x, , Executing an
-extended command, emacs, the GNU Emacs Manual}, for more detailed
-information.} command name (displayed in parentheses), and a short
-description of what the command does. All of the cursor motion commands
-can take an @dfn{numeric} argument (@pxref{Miscellaneous Commands,
-@code{universal-argument}}), to find out how to supply them. With a
-numeric argument, the motion commands are simply executed that
-many times; for example, a numeric argument of 4 given to
-@code{next-line} causes the cursor to move down 4 lines. With a
-negative numeric argument, the motion is reversed; an argument of -4
-given to the @code{next-line} command would cause the cursor to move
-@emph{up} 4 lines.
-
-@table @asis

-@chapter Moving Text Within a Window
-@cindex scrolling
-
-Sometimes you are looking at a screenful of text, and only part of the

-@item @code{SPC} (@code{scroll-forward})
-@itemx @code{C-v}
-@kindex SPC, in Info windows
-@kindex C-v
-@findex scroll-forward
-Shift the text in this window up. That is, show more of the node which
-is currently below the bottom of the window. With a numeric argument,
-show that many more lines at the bottom of the window; a numeric
-argument of 4 would shift all of the text in the window up 4 lines
-(discarding the top 4 lines), and show you four new lines at the bottom
-of the window. Without a numeric argument, @key{SPC} takes the bottom
-two lines of the window and places them at the top of the window,
-redisplaying almost a completely new screenful of lines.
-
-@item @code{DEL} (@code{scroll-backward})
-@itemx @code{M-v}
-@kindex DEL, in Info windows
-@kindex M-v
-@findex scroll-backward
-Shift the text in this window down. The inverse of
-@code{scroll-forward}.
-
-@end table
-
-@cindex scrolling through node structure
-The @code{scroll-forward} and @code{scroll-backward} commands can also
-move forward and backward through the node structure of the file. If
-you press @key{SPC} while viewing the end of a node, or @key{DEL} while
-viewing the beginning of a node, what happens is controlled by the
-variable @code{scroll-behaviour}. @xref{Variables,
-@code{scroll-behaviour}}, for more information.
-
-@table @asis
-@item @code{C-l} (@code{redraw-display})
-@kindex C-l
-@findex redraw-display
-Redraw the display from scratch, or shift the line containing the cursor
-to a specified location. With no numeric argument, @samp{C-l} clears
-the screen, and then redraws its entire contents. Given a numeric
-argument of @var{n}, the line containing the cursor is shifted so that
-it is on the @var{n}th line of the window.
-
-@item @code{C-x w} (@code{toggle-wrap})
-@kindex C-w
-@findex toggle-wrap
-Toggles the state of line wrapping in the current window. Normally,
-lines which are longer than the screen width @dfn{wrap}, i.e., they are
-continued on the next line. Lines which wrap have a @samp{\} appearing
-in the rightmost column of the screen. You can cause such lines to be
-terminated at the rightmost column by changing the state of line
-wrapping in the window with @code{C-x w}. When a line which needs more
-space than one screen width to display is displayed, a @samp{$} appears
-in the rightmost column of the screen, and the remainder of the line is
-invisible.
-@end table
-
-@node Node Commands
-@chapter Selecting a New Node
-@cindex nodes, selection of
-
-This section details the numerous Info commands which select a new node
-to view in the current window.
-
-The most basic node commands are @samp{n}, @samp{p}, @samp{u}, and
-@samp{l}.
-
-When you are viewing a node, the top line of the node contains some Info
-@dfn{pointers} which describe where the next, previous, and up nodes
-are. Info uses this line to move about the node structure of the file
-when you use the following commands:
-
-@table @asis
-@item @code{n} (@code{next-node})
-@kindex n
-@findex next-node
-Selects the `Next' node.
-
-@item @code{p} (@code{prev-node})
-@kindex p
-@findex prev-node
-Selects the `Prev' node.
-
-@item @code{u} (@code{up-node})
-@kindex u
-@findex up-node
-Selects the `Up' node.
-@end table
-
-You can easily select a node that you have already viewed in this window
-by using the @samp{l} command -- this name stands for "last", and
-actually moves through the list of already visited nodes for this
-window. @samp{l} with a negative numeric argument moves forward through
-the history of nodes for this window, so you can quickly step between
-two adjacent (in viewing history) nodes.
-
-@table @asis
-@item @code{l} (@code{history-node})
-@kindex l
-@findex history-node
-Selects the most recently selected node in this window.
-@end table
-
-Two additional commands make it easy to select the most commonly
-selected nodes; they are @samp{t} and @samp{d}.
-
-@table @asis
-@item @code{t} (@code{top-node})
-@kindex t
-@findex top-node
-Selects the node @samp{Top} in the current info file.
-
-@item @code{d} (@code{dir-node})
-@kindex d
-@findex dir-node
-Selects the directory node (i.e., the node @samp{(dir)}).
-@end table
-
-Here are some other commands which immediately result in the selection
-of a different node in the current window:
-
-@table @asis
-@item @code{<} (@code{first-node})
-@kindex <
-@findex first-node
-Selects the first node which appears in this file. This node is most
-often @samp{Top}, but it doesn't have to be.
-
-@item @code{>} (@code{last-node})
-@kindex >
-@findex last-node
-Selects the last node which appears in this file.
-
-@item @code{]} (@code{global-next-node})
-@kindex ]
-@findex global-next-node
-Moves forward or down through node structure. If the node that you are
-currently viewing has a @samp{Next} pointer, that node is selected.
-Otherwise, if this node has a menu, the first menu item is selected. If
-there is no @samp{Next} and no menu, the same process is tried with the
-@samp{Up} node of this node.
-
-@item @code{[} (@code{global-prev-node})
-@kindex [
-@findex global-prev-node
-Moves backward or up through node structure. If the node that you are
-currently viewing has a @samp{Prev} pointer, that node is selected.
-Otherwise, if the node has an @samp{Up} pointer, that node is selected,
-and if it has a menu, the last item in the menu is selected.
-@end table
-
-You can get the same behaviour as @code{global-next-node} and
-@code{global-prev-node} while simply scrolling through the file with
-@key{SPC} and @key{DEL}; @xref{Variables, @code{scroll-behaviour}}, for
-more information.
-
-@table @asis
-@item @code{g} (@code{goto-node})
-@kindex g
-@findex goto-node
-Reads the name of a node and selects it. No completion is done while
-reading the node name, since the desired node may reside in a separate
-file. The node must be typed exactly as it appears in the info file. A
-file name may be included as with any node specification, for example
-
-@example
-@code{g(emacs)Buffers}
-@end example
-
-finds the node @samp{Buffers} in the info file @file{emacs}.
-
-@item @code{C-x k} (@code{kill-node})
-@kindex C-x k
-@findex kill-node
-Kills a node. The node name is prompted for in the echo area, with a
-default of the current node. @dfn{Killing} a node means that Info tries
-hard to forget about it, removing it from the list of history nodes kept
-for the window where that node is found. Another node is selected in
-the window which contained the killed node.
-
-@item @code{C-x C-f} (@code{view-file})
-@kindex C-x C-f
-@findex view-file
-Reads the name of a file and selects the entire file. The command
-@example
-@code{C-x C-f @var{filename}}
-@end example
-is equivalent to typing
-@example
-@code{g(@var{filename})*}
-@end example
-
-@item @code{C-x C-b} (@code{list-visited-nodes})
-@kindex C-x C-b
-@findex list-visited-nodes
-Makes a window containing a menu of all of the currently visited nodes.
-This window becomes the selected window, and you may use the standard
-Info commands within it.
-
-@item @code{C-x b} (@code{select-visited-node})
-@kindex C-x b
-@findex select-visited-node
-Selects a node which has been previously visited in a visible window.
-This is similar to @samp{C-x C-b} followed by @samp{m}, but no window is
-created.

-@node Searching Commands
-@chapter Searching an Info File
-@cindex searching
-
-GNU Info allows you to search for a sequence of characters throughout an
-entire info file, search through the indices of an info file, or find
-areas within an info file which discuss a particular topic.
-
-@table @asis
-@item @code{s} (@code{search})
-@kindex s
-@findex search
-Reads a string in the echo area and searches for it.
-
-@item @code{C-s} (@code{isearch-forward})
-@kindex C-s
-@findex isearch-forward
-Interactively searches forward through the info file for a string as you
-type it.
-
-@item @code{C-r} (@code{isearch-backward})
-@kindex C-r
-@findex isearch-backward
-Interactively searches backward through the info file for a string as
-you type it.
-
-@item @code{i} (@code{index-search})
-@kindex i
-@findex index-search
-Looks up a string in the indices for this info file, and selects a node
-where the found index entry points to.
-
-@item @code{,} (@code{next-index-match})
-@kindex ,
-@findex next-index-match
-Moves to the node containing the next matching index item from the last
-@samp{i} command.
-@end table
-
-The most basic searching command is @samp{s} (@code{search}). The
-@samp{s} command prompts you for a string in the echo area, and then
-searches the remainder of the info file for an ocurrence of that string.
-If the string is found, the node containing it is selected, and the
-cursor is left positioned at the start of the found string. Subsequent
-@samp{s} commands show you the default search string within @samp{[} and
-@samp{]}; pressing @key{RET} instead of typing a new string will use the
-default search string.
-
-@dfn{Incremental searching} is similar to basic searching, but the
-string is looked up while you are typing it, instead of waiting until
-the entire search string has been specified.
-
-@node Xref Commands
-@chapter Selecting Cross References
-
-We have already discussed the @samp{Next}, @samp{Prev}, and @samp{Up}
-pointers which appear at the top of a node. In addition to these
-pointers, a node may contain other pointers which refer you to a
-different node, perhaps in another info file. Such pointers are called
-@dfn{cross references}, or @dfn{xrefs} for short.
-
-@menu
-* Parts of an Xref:: What a cross reference is made of.
-* Selecting Xrefs:: Commands for selecting menu or note items.
-@end menu
-
-@node Parts of an Xref
-@section Parts of an Xref
-
-Cross references have two major parts: the first part is called the
-@dfn{label}; it is the name that you can use to refer to the cross
-reference, and the second is the @dfn{target}; it is the full name of
-the node that the cross reference points to.
-
-The target is separated from the label by a colon @samp{:}; first the
-label appears, and then the target. For example, in the sample menu
-cross reference below, the single colon separates the label from the
-target.
-
-@example
-* Foo Label: Foo Target. More information about Foo.
-@end example
-
-Note the @samp{.} which ends the name of the target. The @samp{.} is
-not part of the target; it serves only to let Info know where the target
-name ends.
-
-A shorthand way of specifying references allows two adjacent colons to
-stand for a target name which is the same as the label name:
-
-@example
-* Foo Commands:: Commands pertaining to Foo.
-@end example
-
-In the above example, the name of the target is the same as the name of
-the label, in this case @code{Foo Commands}.
-
-You will normally see two types of cross references while viewing nodes:
-@dfn{menu} references, and @dfn{note} references. Menu references
-appear within a node's menu; they begin with a @samp{*} at the beginning
-of a line, and continue with a label, a target, and a comment which
-describes what the contents of the node pointed to contains.
-
-Note references appear within the body of the node text; they begin with
-@code{*Note}, and continue with a label and a target.
-
-Like @samp{Next}, @samp{Prev} and @samp{Up} pointers, cross references
-can point to any valid node. They are used to refer you to a place
-where more detailed information can be found on a particular subject.
-Here is a cross reference which points to a node within the Texinfo
-documentation: @xref{xref, , Writing an Xref, texinfo, the Texinfo
-Manual}, for more information on creating your own texinfo cross
-references.
-
-@node Selecting Xrefs
-@section Selecting Xrefs
-
-The following table lists the Info commands which operate on menu items.
-
-@table @asis
-@item @code{1} (@code{menu-digit})
-@itemx @code{2} @dots{} @code{9}
-@cindex 1 @dots{} 9, in Info windows
-@kindex 1 @dots{} 9, in Info windows
-@findex menu-digit
-Within an Info window, pressing a single digit, (such as @samp{1}),
-selects that menu item, and places its node in the current window.
-For convenience, there is one exception; pressing @samp{0} selects the
-@emph{last} item in the node's menu.
-
-@item @code{0} (@code{last-menu-item})
-@kindex 0, in Info windows
-@findex last-menu-item
-Select the last item in the current node's menu.
-
-@item @code{m} (@code{menu-item})
-@kindex m
-@findex menu-item
-Reads the name of a menu item in the echo area and selects its node.
-Completion is available while reading the menu label.
-
-@item @code{M-x find-menu}
-@findex find-menu
-Moves the cursor to the start of this node's menu.
-@end table
-
-This table lists the Info commands which operate on note cross references.
-
-@table @asis
-@item @code{f} (@code{xref-item})
-@itemx @code{r}
-@kindex f
-@kindex r
-@findex xref-item
-Reads the name of a note cross reference in the echo area and selects
-its node. Completion is available while reading the cross reference
-label.
-@end table
-
-Finally, the next few commands operate on menu or note references alike:
-
-@table @asis
-@item @code{TAB} (@code{move-to-next-xref})
-@kindex TAB, in Info windows
-@findex move-to-next-xref
-Moves the cursor to the start of the next nearest menu item or note
-reference in this node. You can then use @key{RET}
-(@code{select-reference-this-line} to select the menu or note reference.
-
-@item @code{M-TAB} (@code{move-to-prev-xref})
-@kindex M-TAB, in Info windows
-@findex move-to-prev-xref
-Moves the cursor the start of the nearest previous menu item or note
-reference in this node.
-
-@item @code{RET} (@code{select-reference-this-line})
-@kindex RET, in Info windows
-@findex select-reference-this-line
-Selects the menu item or note reference appearing on this line.
-@end table
-
-@node Window Commands
-@chapter Manipulating Multiple Windows
-@cindex windows, manipulating
-
-A @dfn{window} is a place to show the text of a node. Windows have a
-view area where the text of the node is displayed, and an associated
-@dfn{mode line}, which briefly describes the node being viewed.
-
-GNU Info supports multiple windows appearing in a single screen; each
-window is separated from the next by its modeline. At any time, there
-is only one @dfn{active} window, that is, the window in which the cursor
-appears. There are commands available for creating windows, changing
-the size of windows, selecting which window is active, and for deleting
-windows.
-
-@menu
-* The Mode Line:: What appears in the mode line?
-* Basic Windows:: Manipulating windows in Info.
-* The Echo Area:: Used for displaying errors and reading input.
-@end menu
-
-@node The Mode Line
-@section The Mode Line
-
-A @dfn{mode line} is a line of inverse video which appears at the bottom
-of an info window. It describes the contents of the window just above
-it; this information includes the name of the file and node appearing in
-that window, the number of screen lines it takes to display the node,
-and the percentage of text that is above the top of the window. It can
-also tell you if the indirect tags table for this info file needs to be
-updated, and whether or not the info file was compressed when stored on
-disk.
-
-Here is a sample mode line for a window containing an uncompressed file
-named @file{dir}, showing the node @samp{Top}.
-
-@example
------Info: (dir)Top, 40 lines --Top---------------------------------------
- ^^ ^ ^^^ ^^
- (file)Node #lines where
-@end example
-
-When a node comes from a file which is compressed on disk, this is
-indicated in the mode line with two small @samp{z}'s. In addition, if
-the info file containing the node has been split into subfiles, the name
-of the subfile containing the node appears in the modeline as well:
-
-@example
---zz-Info: (emacs)Top, 291 lines --Top-- Subfile: emacs-1.Z---------------
-@end example
-
-When Info makes a node internally, such that there is no corresponding
-info file on disk, the name of the node is surrounded by asterisks
-(@samp{*}). The name itself tells you what the contents of the window
-are; the sample mode line below shows an internally constructed node
-showing possible completions:
-
-@example
------Info: *Completions*, 7 lines --All-----------------------------------
-@end example
-
-@node Basic Windows
-@section Window Commands
-
-It can be convenient to view more than one node at a time. To allow
-this, Info can display more than one @dfn{window}. Each window has its
-own mode line (@pxref{The Mode Line}) and history of nodes viewed in that
-window (@pxref{Node Commands, , @code{history-node}}).
-
-@table @asis
-@item @code{C-x o} (@code{next-window})
-@cindex windows, selecting
-@kindex C-x o
-@findex next-window
-Selects the next window on the screen. Note that the echo area can only be
-selected if it is already in use, and you have left it temporarily.
-Normally, @samp{C-x o} simply moves the cursor into the next window on
-the screen, or if you are already within the last window, into the first
-window on the screen. Given a numeric argument, @samp{C-x o} moves over
-that many windows. A negative argument causes @samp{C-x o} to select
-the previous window on the screen.
-
-@item @code{M-x prev-window}
-@findex prev-window
-Selects the previous window on the screen. This is identical to
-@samp{C-x o} with a negative argument.
-
-@item @code{C-x 2} (@code{split-window})
-@cindex windows, creating
-@kindex C-x 2
-@findex split-window
-Splits the current window into two windows, both showing the same node.
-Each window is one half the size of the original window, and the cursor
-remains in the original window. The variable @code{automatic-tiling}
-can cause all of the windows on the screen to be resized for you
-automatically, please @pxref{Variables, , automatic-tiling} for more
-information.
-
-@item @code{C-x 0} (@code{delete-window})
-@cindex windows, deleting
-@kindex C-x 0
-@findex delete-window
-Deletes the current window from the screen. If you have made too many
-windows and your screen appears cluttered, this is the way to get rid of
-some of them.
-
-@item @code{C-x 1} (@code{keep-one-window})
-@kindex C-x 1
-@findex keep-one-window
-Deletes all of the windows excepting the current one.
-
-@item @code{ESC C-v} (@code{scroll-other-window})
-@kindex ESC C-v, in Info windows
-@findex scroll-other-window
-Scrolls the other window, in the same fashion that @samp{C-v} might
-scroll the current window. Given a negative argument, the "other"
-window is scrolled backward.
-
-@item @code{C-x ^} (@code{grow-window})
-@kindex C-x ^
-@findex grow-window
-Grows (or shrinks) the current window. Given a numeric argument, grows
-the current window that many lines; with a negative numeric argument,
-the window is shrunk instead.
-
-@item @code{C-x t} (@code{tile-windows})
-@cindex tiling
-@kindex C-x t
-@findex tile-windows
-Divides the available screen space among all of the visible windows.
-Each window is given an equal portion of the screen in which to display
-its contents. The variable @code{automatic-tiling} can cause
-@code{tile-windows} to be called when a window is created or deleted.
-@xref{Variables, , @code{automatic-tiling}}.
-@end table
-
-@node The Echo Area
-@section The Echo Area
-@cindex echo area
-
-The @dfn{echo area} is a one line window which appears at the bottom of
-the screen. It is used to display informative or error messages, and to
-read lines of input from you when that is necessary. Almost all of the
-commands available in the echo area are identical to their Emacs
-counterparts, so please refer to that documentation for greater depth of
-discussion on the concepts of editing a line of text. The following
-table briefly lists the commands that are available while input is being
-read in the echo area:
-
-@table @asis
-@item @code{C-f} (@code{echo-area-forward})
-@kindex C-f, in the echo area
-@findex echo-area-forward
-Moves forward a character.

-
-@item @code{DEL} (@code{echo-area-rubout})
-@kindex DEL, in the echo area
-@findex echo-area-rubout
-Deletes the character behind the cursor.
-
-@item @code{C-g} (@code{echo-area-abort})
-@kindex C-g, in the echo area
-@findex echo-area-abort
-Cancels or quits the current operation. If completion is being read,
-@samp{C-g} discards the text of the input line which does not match any
-completion. If the input line is empty, @samp{C-g} aborts the calling
-function.
-
-@item @code{RET} (@code{echo-area-newline})
-@kindex RET, in the echo area
-@findex echo-area-newline
-Accepts (or forces completion of) the current input line.
-
-@item @code{C-q} (@code{echo-area-quoted-insert})
-@kindex C-q, in the echo area
-@findex echo-area-quoted-insert
-Inserts the next character verbatim. This is how you can insert control
-characters into a search string, for example.
-
-@item @var{printing character} (@code{echo-area-insert})
-@kindex printing characters, in the echo area
-@findex echo-area-insert
-Inserts the character.
-
-@item @code{M-TAB} (@code{echo-area-tab-insert})
-@kindex M-TAB, in the echo area
-@findex echo-area-tab-insert

-The next group of commands deal with @dfn{killing}, and @dfn{yanking}
-text. For an in depth discussion of killing and yanking,
-@pxref{Killing, , Killing and Deleting, emacs, the GNU Emacs Manual}
-
-@table @asis
-@item @code{M-d} (@code{echo-area-kill-word})
-@kindex M-d, in the echo area
-@findex echo-area-kill-word

-@item @code{M-DEL} (@code{echo-area-backward-kill-word})
-@kindex M-DEL, in the echo area
-@findex echo-area-backward-kill-word
-Kills the word preceding the cursor.

-
-@item @code{C-y} (@code{echo-area-yank})
-@kindex C-y, in the echo area
-@findex echo-area-yank
-Yanks back the contents of the last kill.
-
-@item @code{M-y} (@code{echo-area-yank-pop})
-@kindex M-y, in the echo area
-@findex echo-area-yank-pop
-Yanks back a previous kill, removing the last yanked text first.
-@end table
-
-Sometimes when reading input in the echo area, the command that needed
-input will only accept one of a list of several choices. The choices
-represent the @dfn{possible completions}, and you must respond with one
-of them. Since there are a limited number of responses you can make,
-Info allows you to abbreviate what you type, only typing as much of the
-response as is necessary to uniquely identify it. In addition, you can
-request Info to fill in as much of the response as is possible; this
-is called @dfn{completion}.
-
-The following commands are available when completing in the echo area:
-
-@table @asis
-@item @code{TAB} (@code{echo-area-complete})
-@itemx @code{SPC}
-@kindex TAB, in the echo area
-@kindex SPC, in the echo area
-@findex echo-area-complete
-Inserts as much of a completion as is possible.
-
-@item @code{?} (@code{echo-area-possible-completions})
-@kindex ?, in the echo area
-@findex echo-area-possible-completions
-Displays a window containing a list of the possible completions of what
-you have typed so far. For example, if the available choices are:
-@example
-bar
-foliate
-food
-forget
-@end example
-and you have typed an @samp{f}, followed by @samp{?}, the possible
-completions would contain:
-@example
-foliate
-food
-forget
-@end example
-i.e., all of the choices which begin with @samp{f}. Pressing @key{SPC}
-or @key{TAB} would result in @samp{fo} appearing in the echo area, since
-all of the choices which begin with @samp{f} continue with @samp{o}.
-Now, typing @samp{l} followed by @samp{TAB} results in @samp{foliate}
-appearing in the echo area, since that is the only choice which begins
-with @samp{fol}.
-
-@item @code{ESC C-v} (@code{echo-area-scroll-completions-window})
-@kindex ESC C-v, in the echo area
-@findex echo-area-scroll-completions-window
-Scrolls the completions window, if that is visible, or the "other"
-window if not.

-@node Printing Nodes
-@chapter Printing Out Nodes
-@cindex printing
-
-You may wish to print out the contents of a node as a quick reference
-document for later use. Info provides you with a command for doing
-this. In general, we recommend that you use @TeX{} to format the

-
-@item @code{M-x describe-key}
-@cindex keys, describing
-@findex describe-key
-Reads a key sequence in the echo area, and then displays the name and
-documentation of the Info command that the key sequence invokes.

-@item @code{M-x describe-variable}
-Reads the name of a variable in the echo area and then displays a brief
-description of what the variable affects.
-
-@item @code{M-x where-is}
-@findex where-is
-Reads the name of an Info command in the echo area, and then displays
-a key sequence which can be typed in order to invoke that command.

-@item @code{C-h} (@code{get-help-window})
-@itemx @code{?}
-@kindex C-h
-@kindex ?, in Info windows
-@findex get-help-window
-Creates (or moves into) the window displaying @code{*Help*}, and places
-a node containing a quick reference card into it. This window displays
-the most concise information about GNU Info available.
-
-@item @code{h} (@code{get-info-help-node})
-@kindex h
-@findex get-info-help-node
-Tries hard to visit the node @code{(info)Help}. The info file
-@file{info.texi} distributed with GNU Info contains this node. Of
-course, the file must first be processed with @code{makeinfo}, and then
-placed into the location of your info directory.

-
-@table @asis
-@item @code{C-u} (@code{universal-argument})
-@cindex numeric arguments
-@kindex C-u
-@findex universal-argument
-Starts (or multiplies by 4) the current numeric argument. @samp{C-u} is
-a good way to give a small numeric argument to cursor movement or
-scrolling commands; @samp{C-u C-v} scrolls the screen 4 lines, while
-@samp{C-u C-u C-n} moves the cursor down 16 lines.
-
-@item @code{M-1} (@code{add-digit-to-numeric-arg})
-@itemx @code{M-2} @dots{} @code{M-9}
-@kindex M-1 @dots{} M-9
-@findex add-digit-to-numeric-arg
-Adds the digit value of the invoking key to the current numeric
-argument. Once Info is reading a numeric argument, you may just type
-the digits of the argument, without the Meta prefix. For example, you
-might give @samp{C-l} a numeric argument of 32 by typing:
-
-@example
-@kbd{C-u 3 2 C-l}
-@end example
-or
-@example
-@kbd{M-3 2 C-l}
-@end example
-@end table

-Info commands. You can change the values of these variables, and thus
-change the behaviour of Info to more closely match your environment and
-info file reading manner.
-
-@table @asis
-@item @code{M-x set-variable}
-@cindex variables, setting
-@findex set-variable
-Reads the name of a variable, and the value for it, in the echo area and
-then sets the variable to that value. Completion is available when
-reading the variable name; often, completion is available when reading
-the value to give to the variable, but that depends on the variable
-itself. If a variable does @emph{not} supply multiple choices to
-complete over, it expects a numeric value.
-
-@item @code{M-x describe-variable}
-@cindex variables, describing
-@findex describe-variable
-Reads the name of a variable in the echo area and then displays a brief
-description of what the variable affects.
-@end table
-
-Here is a list of the variables that you can set in Info.
-
-@table @code
-@item automatic-footnotes
-@vindex automatic-footnotes
-When set to @code{On}, footnotes appear and disappear automatically.
-This variable is @code{On} by default. When a node is selected, a
-window containing the footnotes which appear in that node is created,
-and the footnotes are displayed within the new window. The window that
-Info creates to contain the footnotes is called @samp{*Footnotes*}. If
-a node is selected which contains no footnotes, and a @samp{*Footnotes*}
-window is on the screen, the @samp{*Footnotes*} window is deleted.
-Footnote windows created in this fashion are not automatically tiled so
-that they can use as little of the display as is possible.
-
-@item automatic-tiling
-@vindex automatic-tiling
-When set to @code{On}, creating or deleting a window resizes other
-windows. This variable is @code{Off} by default. Normally, typing
-@samp{C-x 2} divides the current window into two equal parts. When
-@code{automatic-tiling} is set to @code{On}, all of the windows are
-resized automatically, keeping an equal number of lines visible in each
-window. There are exceptions to the automatic tiling; specifically, the
-windows @samp{*Completions*} and @samp{*Footnotes*} are @emph{not}
-resized through automatic tiling; they remain their original size.
-
-@item visible-bell
-@vindex visible-bell
-When set to @code{On}, GNU Info attempts to flash the screen instead of
-ringing the bell. This variable is @code{Off} by default. Of course,
-Info can only flash the screen if the terminal allows it; in the case
-that the terminal does not allow it, the setting of this variable has no
-effect. However, you can make Info perform quietly by setting the
-@code{errors-ring-bell} variable to @code{Off}.
-
-@item errors-ring-bell
-@vindex errors-ring-bell
-When set to @code{On}, errors cause the bell to ring. The default
-setting of this variable is @code{On}.
-
-@item gc-compressed-files
-@vindex gc-compressed-files
-When set to @code{On}, Info garbage collects files which had to be
-uncompressed. The default value of this variable is @code{Off}.
-Whenever a node is visited in Info, the info file containing that node
-is read into core, and Info reads information about the tags and nodes
-contained in that file. Once the tags information is read by Info, it
-is never forgotten. However, the actual text of the nodes does not need
-to remain in core unless a particular info window needs it. For
-non-compressed files, the text of the nodes does not remain in core when
-it is no longer in use. But de-compressing a file can be a time
-consuming operation, and so Info tries hard not to do it twice.
-@code{gc-compressed-files} tells Info it is okay to garbage collect the
-text of the nodes of a file which was compressed on disk.
-
-@item show-index-match
-@vindex show-index-match
-When set to @code{On}, the portion of the matched search string is
-highlighted in the message which explains where the matched search
-string was found. The default value of this variable is @code{On}.
-When Info displays the location where an index match was found,
-(@pxref{Searching Commands, , @code{next-index-match}}), the portion of the
-string that you had typed is highlighted by displaying it in the inverse
-case from its surrounding characters.
-
-@item scroll-behaviour
-@vindex scroll-behaviour
-Controls what happens when forward scrolling is requested at the end of
-a node, or when backward scrolling is requested at the beginning of a
-node. The default value for this variable is @code{Continuous}. There
-are three possible values for this variable:
-
-@table @code
-@item Continuous
-Tries to get the first item in this node's menu, or failing that, the
-@samp{Next} node, or failing that, the @samp{Next} of the @samp{Up}.
-This behaviour is identical to using the @samp{]}
-(@code{global-next-node}) and @samp{[} (@code{global-prev-node})
-commands.
-
-@item Next Only
-Only tries to get the @samp{Next} node.
-
-@item Page Only
-Simply gives up, changing nothing. If @code{scroll-behaviour} is
-@code{Page Only}, no scrolling command can change the node that is being
-viewed.
-@end table
-
-@item scroll-step
-@vindex scroll-step
-The number of lines to scroll when the cursor moves out of the window.
-Scrolling happens automatically if the cursor has moved out of the
-visible portion of the node text when it is time to display. Usually
-the scrolling is done so as to put the cursor on the center line of the
-current window. However, if the variable @code{scroll-step} has a
-nonzero value, Info attempts to scroll the node text by that many lines;
-if that is enough to bring the cursor back into the window, that is what
-is done. The default value of this variable is 0, thus placing the
-cursor (and the text it is attached to) in the center of the window.
-Setting this variable to 1 causes a kind of "smooth scrolling" which
-some people prefer.
-
-@item ISO-Latin
-@cindex ISO Latin characters
-@vindex ISO-Latin
-When set to @code{On}, Info accepts and displays ISO Latin characters.
-By default, Info assumes an ASCII character set. @code{ISO-Latin} tells
-Info that it is running in an environment where the European standard
-character set is in use, and allows you to input such characters to
-Info, as well as display them.

-@chapter The Macro Facility
-
-This chapter describes the new macro facility.
-
-A @dfn{macro} is a command that you define in terms of other commands.
-It doesn't exist as a @texinfo{} command until you define it as part of
-the input file to @makeinfo{}. Once the command exists, it behaves much
-as any other @texinfo{} command. Macros are a useful way to ease the
-details and tedium of writing a `correct' info file. The following
-sections explain how to write and invoke macros.
-
-@menu
-* How to Use Macros in @texinfo{}::
- How to use the macro facility.
-
-* Using Macros Recursively::
- How to write a macro which does (or doesn't) recurse.
-
-* Using @texinfo{} Macros As Arguments::
- Passing a macro as an argument.
-@end menu
-
-@section How to Use Macros in @texinfo{}
-
-Using macros in @texinfo{} is easy. First you define the macro. After
-that, the macro command is available as a normal @texinfo{} command.
-Here is what a definition looks like:
-
-@example
-@@macro @var{name}@{@var{arg1}, @var{@dots{}} @var{argn}@}
-@var{@texinfo{} commands@dots{}}
-@@end macro
-@end example
-
-The arguments that you specify that the macro takes are expanded with
-the actual parameters used when calling the macro if they are seen
-surrounded by backslashes. For example, here is a definition of
-@code{@@codeitem}, a macro which can be used wherever @code{@@item} can
-be used, but which surrounds its argument with @code{@@code@{@dots{}@}}.
-
-@example
-@@macro codeitem@{item@}
-@@item @@code@{\item\@}
-@@end macro
-@end example
-
-When the macro is expanded, all of the text between the @code{@@macro}
-and @code{@@end macro} is inserted into the document at the expansion
-point, with the actual parameters substituted for the named parameters.
-So, a call to the above macro might look like:
-
-@example
-@@codeitem@{Foo@}
-@end example
-
-and @makeinfo{} would execute the following code:
-
-@example
-@@item @@code@{Foo@}
-@end example
-
-A special case is made for macros which only take a single argument, and
-which are invoked without any brace characters (i.e.,
-@samp{@{}@dots{}@samp{@}}) surrounding an argument; the rest of the line
-is supplied as is as the sole argument to the macro. This special case
-allows one to redefine some standard @texinfo{} commands without
-modifying the input file. Along with the non-recursive action of macro
-invocation, one can easily redefine the sectioning commands to also
-provide index entries:
-
-@example
-@@macro chapter@{name@}
-@@chapter \name\
-@@findex \name\
-@@end macro
-@end example
-
-Thus, the text:
-
-@example
-@@chapter strlen
-@end example
-
-will expand to:
-
-@example
-@@chapter strlen
-@@findex strlen
-@end example
-
-@section Using Macros Recursively
-
-Normally, while a particular macro is executing, any call to that macro
-will be seen as a call to a builtin @texinfo{} command. This allows one
-to redefine a builtin @texinfo{} command as a macro, and then use that
-command within the definition of the macro itself. For example, one
-might wish to make sure that whereever a term was defined with
-@code{@@dfn@{@dots{}@}}, the location of the definition would appear
-in the concept index for the manual. Here is a macro which redefines
-@code{@@dfn} to do just that:
-
-@example
-@@macro dfn@{text@}
-@@dfn@{\text\@}
-@@cpindex \text\
-@@end macro
-@end example
-
-Note that we used the builtin @texinfo{} command @code{@@dfn} within our
-overriding macro definition.
-
-This behaviour itself can be overridden for macro execution by writing a
-special @dfn{macro control command} in the definition of the macro. The
-command is considered special because it doesn't affect the output text
-directly, rather, it affects the way in which the macro is defined. One
-such special command is @code{@@allow-recursion}.
-
-@example
-@@macro silly@{arg@}
-@@allow-recursion
-\arg\
-@@end macro
-@end example
-
-Now @code{@@silly} is a macro that can be used within a call to itself:
-
-@example
-This text @@silly@{@@silly@{some text@}@} is ``some text''.
-@end example

-@node Formatting Control
-@section Controlling Paragraph Formats
-
-Without any special options, @code{makeinfo} @dfn{fills} the paragraphs that
-it outputs to an Info file. Filling is the process of breaking and connecting
-lines so that lines are the same length as or shorter than the number
-specified as the fill column. Lines are broken between words. With
-@code{makeinfo}, you can control:
-
-@itemize @bullet
-@item
-The width of each paragraph (the @dfn{fill-column}).
-@item
-The amount of indentation that the first line of
-each paragraph receives (the @dfn{paragraph-indentation}).
-@end itemize
-
-@node Options
-@section Command Line Options
-
-The following command line options are available for @code{makeinfo}.
-
-@need 100
-@table @code
-@item -D @var{var}
-Cause @var{var} to be defined. This is equivalent to
-@code{@@set @var{var}} in the Texinfo file.
-
-@need 150
-@item --error-limit @var{limit}
-Set the maximum number of errors that @code{makeinfo} will report
-before exiting (on the assumption that continuing would be useless).
-The default number of errors that can be reported before
-@code{makeinfo} gives up is 100.@refill
-
-@need 150
-@item --fill-column @var{width}
-Specify the maximum number of columns in a line; this is the right-hand
-edge of a line. Paragraphs that are filled will be filled to this
-width. The default value for @code{fill-column} is 72.
-@refill
-
-@item --footnote-style @var{style}
-Set the footnote style to @var{style}, either @samp{end} for the end
-node style or @samp{separate} for the separate node style. The value
-set by this option overrides the value set in a Texinfo file by an
-@code{@@footnotestyle} command. When the footnote style is
-@samp{separate}, @code{makeinfo} makes a new node containing the
-footnotes found in the current node. When the footnote style is
-@samp{end}, @code{makeinfo} places the footnote references at the end
-of the current node.@refill
-
-@need 150
-@item -I @var{dir}
-Add @code{dir} to the directory search list for finding files that are
-included using the @code{@@include} command. By default,
-@code{makeinfo} searches only the current directory.
-
-@need 150
-@item --no-headers
-Do not include menus or node lines in the output. This results in an
-@sc{ascii} file that you cannot read in Info since it does not contain
-the requisite nodes or menus; but you can print such a file in a
-single, typewriter-like font and produce acceptable output.
-
-@need 150
-@item --no-split
-Suppress the splitting stage of @code{makeinfo}. Normally, large
-output files (where the size is greater than 70k bytes) are split into
-smaller subfiles, each one approximately 50k bytes. If you specify
-@samp{--no-split}, @code{makeinfo} will not split up the output
-file.@refill
-
-@need 100
-@item --no-pointer-validate
-@item --no-validate
-Suppress the pointer-validation phase of @code{makeinfo}. Normally,
-after a Texinfo file is processed, some consistency checks are made to
-ensure that cross references can be resolved, etc.
-@xref{Pointer Validation}.@refill
-
-@need 150
-@item --no-warn
-Suppress the output of warning messages. This does @emph{not}
-suppress the output of error messages, only warnings. You might
-want this if the file you are creating has examples of Texinfo cross
-references within it, and the nodes that are referenced do not actually
-exist.@refill
-
-@item --no-number-footnotes
-Supress automatic footnote numbering. By default, @code{makeinfo}
-numbers each footnote sequentially in a single node, resetting the
-current footnote number to 1 at the start of each node.
-
-@need 150
-@item --output @var{file}
-@itemx -o @var{file}
-Specify that the output should be directed to @var{file} and not to the
-file name specified in the @code{@@setfilename} command found in the Texinfo
-source. @var{file} can be the special token @samp{-}, which specifies
-standard output.
-
-@need 150
-@item --paragraph-indent @var{indent}
-Set the paragraph indentation style to @var{indent}. The value set by
-this option overrides the value set in a Texinfo file by an
-@code{@@paragraphindent} command. The value of @var{indent} is
-interpreted as follows:@refill
-
-@itemize @bullet
-@item
-If the value of @var{indent} is @samp{asis}, do not change the
-existing indentation at the starts of paragraphs.@refill
-
-@item
-If the value of @var{indent} is zero, delete any existing
-indentation.@refill
-
-@item
-If the value of @var{indent} is greater than zero, indent each
-paragraph by that number of spaces.@refill
-@end itemize
-
-@need 100
-@item --reference-limit @var{limit}
-Set the value of the number of references to a node that
-@code{makeinfo} will make without reporting a warning. If a node has more
-than this number of references in it, @code{makeinfo} will make the
-references but also report a warning.@refill
-
-@need 150
-@item -U @var{var}
-Cause @var{var} to be undefined. This is equivalent to
-@code{@@clear @var{var}} in the Texinfo file.
-
-@need 100
-@item --verbose
-Cause @code{makeinfo} to display messages saying what it is doing.
-Normally, @code{makeinfo} only outputs messages if there are errors or
-warnings.@refill
-
-@need 100
-@item --version
-Report the version number of this copy of @code{makeinfo}.@refill
-
-@item --help
-Show a summary of the commend line arguments to @code{makeinfo}.
-@end table
-
-@node Pointer Validation
-@section Pointer Validation
-@cindex Pointer validation with @code{makeinfo}
-@cindex Validation of pointers
-
-If you do not suppress pointer-validation (by using the
-@samp{--no-pointer-validation} option), @code{makeinfo}
-will check the validity of the final Info file. Mostly,
-this means ensuring that nodes you have referenced
-really exist. Here is a complete list of what is
-checked:@refill
-
-@enumerate
-@item
-If a `Next', `Previous', or `Up' node reference is a reference to a
-node in the current file and is not an external reference such as to
-@file{(dir)}, then the referenced node must exist.@refill
-
-@item
-In every node, if the `Previous' node is different from the `Up' node,
-then the `Previous' node must also be pointed to by a `Next' node.@refill
-
-@item
-Every node except the `Top' node must have an `Up' pointer.@refill
-
-@item
-The node referenced by an `Up' pointer must contain a reference to the
-current node in some manner other than through a `Next' reference.
-This includes menu entries and cross references.@refill
-
-@item
-If the `Next' reference of a node is not the same as the `Next' reference
-of the `Up' reference, then the node referenced by the `Next' pointer
-must have a `Previous' pointer that points back to the current node.
-This rule allows the last node in a section to point to the first node
-of the next chapter.@refill
-@end enumerate

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble. Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-% @multitable @columnfractions .25 .3 .45
-% @item ...
-%
-% Numbers following @columnfractions are the percent of the total
-% current hsize to be used for each column. You may use as many
-% columns as desired.
-
-
-% Or use a template:
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item ...
-% using the widest term desired in each column.
-%
-% For those who want to use more than one line's worth of words in
-% the preamble, break the line within one argument and it
-% will parse correctly, i.e.,
-%
-% @multitable {Column 1 template} {Column 2 template} {Column 3
-% template}
-% Not:
-% @multitable {Column 1 template} {Column 2 template}
-% {Column 3 template}
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab, @multitable or @end multitable do not need to be on their
-% own lines, but it will not hurt if they are.
-
-% Sample multitable:
-
-% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-% @item first col stuff @tab second col stuff @tab third col
-% @item
-% first col stuff
-% @tab
-% second col stuff
-% @tab
-% third col
-% @item first col stuff @tab second col stuff
-% @tab Many paragraphs of text may be used in any column.
-%
-% They will wrap at the width determined by the template.
-% @item@tab@tab This will be in third column.
-% @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-% to baseline.
-% 0pt means it depends on current normal line spacing.

-@dfn{Texinfo}@footnote{Note that the first syllable of ``Texinfo'' is
-pronounced like ``speck'', not ``hex''. This odd pronunciation is
-derived from, but is not the same as, the pronunciation of @TeX{}. In
-the word @TeX{}, the @samp{X} is actually the Greek letter ``chi''
-rather than the English letter ``ex''. Pronounce @TeX{} as if the
-@samp{X} were the last sound in the name `Bach'; but pronounce Texinfo
-as if the @samp{x} were a `k'. Spell ``Texinfo'' with a capital ``T''
-and write the other letters in lower case.}
-is a documentation system that uses a single source file to produce both
-on-line information and printed output. This means that instead of
-writing two different documents, one for the on-line help or other on-line
-information and the other for a typeset manual or other printed work, you
-need write only one document. When the work is revised, you need revise
-only one document. (You can read the on-line information, known as an
-@dfn{Info file}, with an Info documentation-reading program.)@refill

-@end ifinfo
-
-Using Texinfo, you can create a printed document with the normal
-features of a book, including chapters, sections, cross references,
-and indices. From the same Texinfo source file, you can create a
-menu-driven, on-line Info file with nodes, menus, cross references,
-and indices. You can, if you wish, make the chapters and sections of
-the printed document correspond to the nodes of the on-line
-information; and you use the same cross references and indices for
-both the Info file and the printed work. @cite{The GNU
-Emacs Manual} is a good example of a Texinfo file, as is this manual.@refill
-
-To make a printed document, you process a Texinfo source file with the
-@TeX{} typesetting program. This creates a @sc{dvi} file that you can
-typeset and print as a book or report. (Note that the Texinfo language
-is completely different from @TeX{}'s usual language, plain @TeX{}.) If
-you do not have @TeX{}, but do have @code{troff} or @code{nroff}, you
-can use the @code{texi2roff} program instead.@refill
-
-To make an Info file, you process a Texinfo source file with the
-@code{makeinfo} utility or Emacs's @code{texinfo-format-buffer} command;
-this creates an Info file that you can install on-line.@refill
-
-@TeX{} and @code{texi2roff} work with many types of printer; similarly,
-Info works with almost every type of computer terminal. This power
-makes Texinfo a general purpose system, but brings with it a constraint,
-which is that a Texinfo file may contain only the customary
-``typewriter'' characters (letters, numbers, spaces, and punctuation
-marks) but no special graphics.@refill
-
-A Texinfo file is a plain @sc{ascii} file containing text and
-@dfn{@@-commands} (words preceded by an @samp{@@}) that tell the
-typesetting and formatting programs what to do. You may edit a
-Texinfo file with any text editor; but it is especially convenient to
-use GNU Emacs since that editor has a special mode, called Texinfo
-mode, that provides various Texinfo-related features. (@xref{Texinfo
-Mode}.)@refill
-
-Before writing a Texinfo source file, you should become familiar with
-the Info documentation reading program and learn about nodes,
-menus, cross references, and the rest. (@inforef{Top, info, info},
-for more information.)@refill
-
-You can use Texinfo to create both on-line help and printed manuals;
-moreover, Texinfo is freely redistributable. For these reasons, Texinfo
-is the format in which documentation for GNU utilities and libraries is
-written.@refill
-
-@node Info Files, Printed Books, Using Texinfo, Overview
-@comment node-name, next, previous, up
-@section Info files
-@cindex Info files
-
-An Info file is a Texinfo file formatted so that the Info documentation
-reading program can operate on it. (@code{makeinfo}
-and @code{texinfo-format-buffer} are two commands that convert a Texinfo file
-into an Info file.)@refill
-
-Info files are divided into pieces called @dfn{nodes}, each of which
-contains the discussion of one topic. Each node has a name, and
-contains both text for the user to read and pointers to other nodes,
-which are identified by their names. The Info program displays one node
-at a time, and provides commands with which the user can move to other
-related nodes.@refill
-
-@ifinfo
-@inforef{Top, info, info}, for more information about using Info.@refill
-@end ifinfo
-
-Each node of an Info file may have any number of child nodes that
-describe subtopics of the node's topic. The names of child
-nodes are listed in a @dfn{menu} within the parent node; this
-allows you to use certain Info commands to move to one of the child
-nodes. Generally, an Info file is organized like a book. If a node
-is at the logical level of a chapter, its child nodes are at the level
-of sections; likewise, the child nodes of sections are at the level
-of subsections.@refill
-
-All the children of any one parent are linked together in a
-bidirectional chain of `Next' and `Previous' pointers. The `Next'
-pointer provides a link to the next section, and the `Previous' pointer
-provides a link to the previous section. This means that all the nodes
-that are at the level of sections within a chapter are linked together.
-Normally the order in this chain is the same as the order of the
-children in the parent's menu. Each child node records the parent node
-name as its `Up' pointer. The last child has no `Next' pointer, and the
-first child has the parent both as its `Previous' and as its `Up'
-pointer.@footnote{In some documents, the first child has no `Previous'
-pointer. Occasionally, the last child has the node name of the next
-following higher level node as its `Next' pointer.}@refill
-
-The book-like structuring of an Info file into nodes that correspond
-to chapters, sections, and the like is a matter of convention, not a
-requirement. The `Up', `Previous', and `Next' pointers of a node can
-point to any other nodes, and a menu can contain any other nodes.
-Thus, the node structure can be any directed graph. But it is usually
-more comprehensible to follow a structure that corresponds to the
-structure of chapters and sections in a printed book or report.@refill
-
-In addition to menus and to `Next', `Previous', and `Up' pointers, Info
-provides pointers of another kind, called references, that can be
-sprinkled throughout the text. This is usually the best way to
-represent links that do not fit a hierarchical structure.@refill
-
-Usually, you will design a document so that its nodes match the
-structure of chapters and sections in the printed output. But there
-are times when this is not right for the material being discussed.
-Therefore, Texinfo uses separate commands to specify the node
-structure for the Info file and the section structure for the printed
-output.@refill
-
-Generally, you enter an Info file through a node that by convention is
-called @samp{Top}. This node normally contains just a brief summary
-of the file's purpose, and a large menu through which the rest of the
-file is reached. From this node, you can either traverse the file
-systematically by going from node to node, or you can go to a specific
-node listed in the main menu, or you can search the index menus and
-then go directly to the node that has the information you want.@refill
-@c !!! With the standalone Info system you may go to specific nodes
-@c directly..
-
-If you want to read through an Info file in sequence, as if it were a
-printed manual, you can get the whole file with the advanced Info
-command @kbd{g* @key{RET}}. (@inforef{Expert, Advanced Info commands,
-info}.)@refill
-
-@c !!! dir file may be located in one of many places:
-@c /usr/local/emacs/info mentioned in info.c DEFAULT_INFOPATH

-@c /usr/gnu/info mentioned in info.c DEFAULT_INFOPATH
-@c /usr/local/info
-@c /usr/local/lib/info
-The @file{dir} file in the @file{info} directory serves as the
-departure point for the whole Info system. From it, you can reach the
-`Top' nodes of each of the documents in a complete Info system.@refill

-@cindex Knuth, Donald
-A Texinfo file can be formatted and typeset as a printed book or manual.
-To do this, you need @TeX{}, a powerful, sophisticated typesetting
-program written by Donald Knuth.@footnote{You can also use the
-@code{texi2roff} program if you do not have @TeX{}; since Texinfo is
-designed for use with @TeX{}, @code{texi2roff} is not described here.
-@code{texi2roff} is part of the standard GNU distribution.}@refill
-
-A Texinfo-based book is similar to any other typeset, printed work: it
-can have a title page, copyright page, table of contents, and preface,
-as well as chapters, numbered or unnumbered sections and subsections,
-page headers, cross references, footnotes, and indices.@refill
-
-You can use Texinfo to write a book without ever having the intention
-of converting it into on-line information. You can use Texinfo for
-writing a printed novel, and even to write a printed memo, although
-this latter application is not recommended since electronic mail is so

-@TeX{} is a general purpose typesetting program. Texinfo provides a
-file called @file{texinfo.tex} that contains information (definitions or
-@dfn{macros}) that @TeX{} uses when it typesets a Texinfo file.
-(@file{texinfo.tex} tells @TeX{} how to convert the Texinfo @@-commands
-to @TeX{} commands, which @TeX{} can then process to create the typeset
-document.) @file{texinfo.tex} contains the specifications for printing
-a document.@refill
-
-Most often, documents are printed on 8.5 inch by 11 inch
-pages (216@dmn{mm} by 280@dmn{mm}; this is the default size), but you
-can also print for 7 inch by 9.25 inch pages (178@dmn{mm} by
-235@dmn{mm}; the @code{@@smallbook} size) or on European A4 size paper
-(@code{@@afourpaper}). (@xref{smallbook, , Printing ``Small'' Books}.
-Also, see @ref{A4 Paper, ,Printing on A4 Paper}.)@refill
-
-By changing the parameters in @file{texinfo.tex}, you can change the
-size of the printed document. In addition, you can change the style in
-which the printed document is formatted; for example, you can change the
-sizes and fonts used, the amount of indentation for each paragraph, the
-degree to which words are hyphenated, and the like. By changing the
-specifications, you can make a book look dignified, old and serious, or
-light-hearted, young and cheery.@refill
-
-@TeX{} is freely distributable. It is written in a dialect of Pascal
-called WEB and can be compiled either in Pascal or (by using a
-conversion program that comes with the @TeX{} distribution) in C.
-(@xref{TeX Mode, ,@TeX{} Mode, emacs, The GNU Emacs Manual}, for information
-about @TeX{}.)@refill
-
-@TeX{} is very powerful and has a great many features. Because a
-Texinfo file must be able to present information both on a
-character-only terminal in Info form and in a typeset book, the
-formatting commands that Texinfo supports are necessarily
-limited.@refill

-
-In a Texinfo file, the commands that tell @TeX{} how to typeset the
-printed manual and tell @code{makeinfo} and
-@code{texinfo-format-buffer} how to create an Info file are preceded
-by @samp{@@}; they are called @dfn{@@-commands}. For example,
-@code{@@node} is the command to indicate a node and @code{@@chapter}
-is the command to indicate the start of a chapter.@refill
-
-@quotation
-@strong{Please note:} All the @@-commands, with the exception of the
-@code{@@TeX@{@}} command, must be written entirely in lower
-case.@refill
-@end quotation
-
-The Texinfo @@-commands are a strictly limited set of constructs. The
-strict limits make it possible for Texinfo files to be understood both
-by @TeX{} and by the code that converts them into Info files. You can
-display Info files on any terminal that displays alphabetic and
-numeric characters. Similarly, you can print the output generated by
-@TeX{} on a wide variety of printers.@refill
-
-Depending on what they do or what arguments@footnote{The word
-@dfn{argument} comes from the way it is used in mathematics and does
-not refer to a disputation between two people; it refers to the
-information presented to the command. According to the @cite{Oxford
-English Dictionary}, the word derives from the Latin for @dfn{to make
-clear, prove}; thus it came to mean `the evidence offered as proof',
-which is to say, `the information offered', which led to its
-mathematical meaning. In its other thread of derivation, the word
-came to mean `to assert in a manner against which others may make
-counter assertions', which led to the meaning of `argument' as a
-disputation.} they take, you need to write @@-commands on lines of
-their own or as part of sentences:@refill
-
-@itemize @bullet
-@item
-Write a command such as @code{@@noindent} at the beginning of a line as
-the only text on the line. (@code{@@noindent} prevents the beginning of
-the next line from being indented as the beginning of a
-paragraph.)@refill
-
-@item
-Write a command such as @code{@@chapter} at the beginning of a line
-followed by the command's arguments, in this case the chapter title, on
-the rest of the line. (@code{@@chapter} creates chapter titles.)@refill

-Write a command such as @code{@@example} at the beginning of a line of
-its own; write the body-text on following lines; and write the matching
-@code{@@end} command, @code{@@end example} in this case, at the

-All printable @sc{ascii} characters except @samp{@@}, @samp{@{} and

-@samp{@@} is the escape character which introduces commands.
-@samp{@{} and @samp{@}} should be used only to surround arguments to

-document, put an @samp{@@} character in front of it, like this:
-@samp{@@@@}, @samp{@@@{}, and @samp{@@@}}.@refill
-
-@ifinfo
-It is customary in @TeX{} to use doubled single-quote characters to
-begin and end quotations: ` ` and ' ' (but without a space between the
-two single-quote characters). This convention should be followed in
-Texinfo files. @TeX{} converts doubled single-quote characters to
-left- and right-hand doubled quotation marks and Info converts doubled
-single-quote characters to @sc{ascii} double-quotes: ` ` and ' ' to " .@refill

-@iftex
-It is customary in @TeX{} to use doubled single-quote characters to
-begin and end quotations: @w{@tt{ `` }} and @w{@tt{ '' }}. This
-convention should be followed in Texinfo files. @TeX{} converts
-doubled single-quote characters to left- and right-hand doubled

-characters to @sc{ascii} double-quotes: @w{@tt{ `` }} and
-@w{@tt{ '' }} to @w{@tt{ " }}.@refill
-@end iftex
-
-Use three hyphens in a row, @samp{---}, for a dash---like this. In

-If you mark off a region of the Texinfo file with the @code{@@iftex}

-
-By convention, the names of Texinfo files end with one of the
-extensions @file{.texinfo}, @file{.texi}, or @file{.tex}. The longer
-extension is preferred since it describes more clearly to a human
-reader the nature of the file. The shorter extensions are for
-operating systems that cannot handle long file names.@refill
-
-In order to be made into a printed manual and an Info file, a Texinfo

-
-@example
-@@bye
-@end example
-
-@findex input @r{(@TeX{} command)}
-@noindent
-The @samp{\input texinfo} line tells @TeX{} to use the
-@file{texinfo.tex} file, which tells @TeX{} how to translate the Texinfo
-@@-commands into @TeX{} typesetting commands. (Note the use of the
-backslash, @samp{\}; this is correct for @TeX{}.) The
-@samp{@@setfilename} line provides a name for the Info file and tells
-@TeX{} to open auxiliary files. The @samp{@@settitle} line specifies a
-title for the page headers (or footers) of the printed manual.@refill
-
-The @code{@@bye} line at the end of the file on a line of its own tells
-the formatters that the file is ended and to stop formatting.@refill
-
-Usually, you will not use quite such a spare format, but will include
-mode setting and start-of-header and end-of-header lines at the
-beginning of a Texinfo file, like this:@refill
-
-@example
-@group
-\input texinfo @@c -*-texinfo-*-
-@@c %**start of header

-@section The Usual GNU Emacs Editing Commands
-
-In most cases, the usual Text mode commands work the same in Texinfo
-mode as they do in Text mode. Texinfo mode adds new editing commands
-and tools to GNU Emacs' general purpose editing features. The major
-difference concerns filling. In Texinfo mode, the paragraph
-separation variable and syntax table are redefined so that Texinfo
-commands that should be on lines of their own are not inadvertently
-included in paragraphs. Thus, the @kbd{M-q} (@code{fill-paragraph})
-command will refill a paragraph but not mix an indexing command on a
-line adjacent to it into the paragraph.@refill
-
-In addition, Texinfo mode sets the @code{page-delimiter} variable to
-the value of @code{texinfo-chapter-level-regexp}; by default, this is
-a regular expression matching the commands for chapters and their
-equivalents, such as appendices. With this value for the page
-delimiter, you can jump from chapter title to chapter title with the
-@kbd{C-x ]} (@code{forward-page}) and @kbd{C-x [}
-(@code{backward-page}) commands and narrow to a chapter with the
-@kbd{C-x p} (@code{narrow-to-page}) command. (@xref{Pages, , ,emacs,
-The GNU Emacs Manual}, for details about the page commands.)@refill
-
-You may name a Texinfo file however you wish, but the convention is to
-end a Texinfo file name with one of the three extensions
-@file{.texinfo}, @file{.texi}, or @file{.tex}. A longer extension is
-preferred, since it is explicit, but a shorter extension may be
-necessary for operating systems that limit the length of file names.
-GNU Emacs automatically enters Texinfo mode when you visit a file with
-a @file{.texinfo} or @file{.texi}
-extension. Also, Emacs switches to Texinfo mode
-when you visit a
-file that has @samp{-*-texinfo-*-} in its first line. If ever you are
-in another mode and wish to switch to Texinfo mode, type @code{M-x
-texinfo-mode}.@refill
-
-Like all other Emacs features, you can customize or enhance Texinfo
-mode as you wish. In particular, the keybindings are very easy to
-change. The keybindings described here are the default or standard

-@kbd{C-c C-c C-d} (@code{texinfo-start-menu-description}) is an insert
-command that works differently from the other insert commands. It
-inserts a node's section or chapter title in the space for the
-description in a menu entry line. (A menu entry has three parts, the
-entry name, the node name, and the description. Only the node name is
-required, but a description helps explain what the node is about.

-description; it positions point at beginning of the inserted text so you
-can edit it. The function does not insert the title if the menu entry
-line already contains a description.@refill
-
-This command is only an aid to writing descriptions; it does not do the
-whole job. You must edit the inserted text since a title tends to use
-the same words as a node name but a useful description uses different
-words.@refill

-Texinfo mode provides commands for automatically creating or updating

-
-You can use the updating commands@refill
-
-@itemize @bullet
-@item
-to insert or update the `Next', `Previous', and `Up' pointers of a
-node,@refill
-
-@item
-to insert or update the menu for a section, and@refill
-
-@item
-to create a master menu for a Texinfo source file.@refill
-@end itemize
-
-You can also use the commands to update all the nodes and menus in a
-region or in a whole Texinfo file.@refill
-
-The updating commands work only with conventional Texinfo files, which
-are structured hierarchically like books. In such files, a structuring
-command line must follow closely after each @code{@@node} line, except
-for the `Top' @code{@@node} line. (A @dfn{structuring command line} is
-a line beginning with @code{@@chapter}, @code{@@section}, or other
-similar command.)
-
-You can write the structuring command line on the line that follows
-immediately after an @code{@@node} line or else on the line that
-follows after a single @code{@@comment} line or a single
-@code{@@ifinfo} line. You cannot interpose more than one line between
-the @code{@@node} line and the structuring command line; and you may
-interpose only an @code{@@comment} line or an @code{@@ifinfo} line.
-
-Commands which work on a whole buffer require that the `Top' node be
-followed by a node with an @code{@@chapter} or equivalent-level command.
-Note that the menu updating commands will not create a main or master
-menu for a Texinfo file that has only @code{@@chapter}-level nodes! The
-menu updating commands only create menus @emph{within} nodes for lower level
-nodes. To create a menu of chapters, you must provide a `Top'
-node.@refill
-
-The menu updating commands remove menu entries that refer to other Info
-files since they do not refer to nodes within the current buffer. This
-is a deficiency. Rather than use menu entries, you can use cross
-references to refer to other Info files. None of the updating commands
-affect cross references.@refill
-
-Texinfo mode has five updating commands that are used most often: two
-are for updating the node pointers or menu of a single node (or a
-region); two are for updating every node pointer and menu in a file;
-and one, the @code{texinfo-master-menu} command, is for creating a
-master menu for a complete file, and optionally, for updating every
-node and menu in the whole Texinfo file.@refill
-
-The @code{texinfo-master-menu} command is the primary command:@refill
-
-@table @kbd
-@item C-c C-u m
-@itemx M-x texinfo-master-menu
-@findex texinfo-master-menu
-Create or update a master menu that includes all the other menus
-(incorporating the descriptions from pre-existing menus, if
-any).@refill
-
-With an argument (prefix argument, @kbd{C-u,} if interactive), first create or
-update all the nodes and all the regular menus in the buffer before
-constructing the master menu. (@xref{The Top Node, , The Top Node and
-Master Menu}, for more about a master menu.)@refill
-
-For @code{texinfo-master-menu} to work, the Texinfo file must have a
-`Top' node and at least one subsequent node.@refill
-
-After extensively editing a Texinfo file, you can type the following:
-
-@example
-C-u M-x texinfo-master-menu
-@exdent or
-C-u C-c C-u m
-@end example
-
-@noindent
-This updates all the nodes and menus completely and all at once.@refill
-@end table
-
-The other major updating commands do smaller jobs and are designed for
-the person who updates nodes and menus as he or she writes a Texinfo
-file.@refill
-
-@need 1000
-The commands are:@refill
-
-@table @kbd
-@item C-c C-u C-n
-@itemx M-x texinfo-update-node
-@findex texinfo-update-node
-Insert the `Next', `Previous', and `Up' pointers for the node that point is
-within (i.e., for the @code{@@node} line preceding point). If the
-@code{@@node} line has pre-existing `Next', `Previous', or `Up'
-pointers in it, the old pointers are removed and new ones inserted.
-With an argument (prefix argument, @kbd{C-u}, if interactive), this command
-updates all @code{@@node} lines in the region (which is the text
-between point and mark).@refill
-
-@item C-c C-u C-m
-@itemx M-x texinfo-make-menu
-@findex texinfo-make-menu
-Create or update the menu in the node that point is within.
-With an argument (@kbd{C-u} as prefix argument, if
-interactive), the command makes or updates menus for the
-nodes which are either within or a part of the
-region.@refill
-
-Whenever @code{texinfo-make-menu} updates an existing menu, the
-descriptions from that menu are incorporated into the new menu. This
-is done by copying descriptions from the existing menu to the entries
-in the new menu that have the same node names. If the node names are
-different, the descriptions are not copied to the new menu.@refill
-
-@item C-c C-u C-e
-@itemx M-x texinfo-every-node-update
-@findex texinfo-every-node-update
-Insert or update the `Next', `Previous', and `Up' pointers for every
-node in the buffer.@refill
-
-@item C-c C-u C-a
-@itemx M-x texinfo-all-menus-update
-@findex texinfo-all-menus-update
-Create or update all the menus in the buffer. With an argument
-(@kbd{C-u} as prefix argument, if interactive), first insert
-or update all the node
-pointers before working on the menus.@refill
-
-If a master menu exists, the @code{texinfo-all-menus-update} command
-updates it; but the command does not create a new master menu if none
-already exists. (Use the @code{texinfo-master-menu} command for
-that.)@refill
-
-When working on a document that does not merit a master menu, you can
-type the following:
-
-@example
-C-u C-c C-u C-a
-@exdent or
-C-u M-x texinfo-all-menus-update
-@end example
-
-@noindent
-This updates all the nodes and menus.@refill
-@end table
-
-The @code{texinfo-column-for-description} variable specifies the
-column to which menu descriptions are indented. By default, the value
-is 32 although it is often useful to reduce it to as low as 24. You
-can set the variable with the @kbd{M-x edit-options} command
-(@pxref{Edit Options, , Editing Variable Values, emacs, The GNU Emacs

-
-Also, the @code{texinfo-indent-menu-description} command may be used to
-indent existing menu descriptions to a specified column. Finally, if
-you wish, you can use the @code{texinfo-insert-node-lines} command to
-insert missing @code{@@node} lines into a file. (@xref{Other Updating

-@node Updating Requirements, Other Updating Commands, Updating Commands, Updating Nodes and Menus
-@comment node-name, next, previous, up
-@subsection Updating Requirements
-@cindex Updating requirements
-@cindex Requirements for updating commands
-
-To use the updating commands, you must organize the Texinfo file
-hierarchically with chapters, sections, subsections, and the like.
-When you construct the hierarchy of the manual, do not `jump down'
-more than one level at a time: you can follow the `Top' node with a
-chapter, but not with a section; you can follow a chapter with a
-section, but not with a subsection. However, you may `jump up' any
-number of levels at one time---for example, from a subsection to a
-chapter.@refill
-
-Each @code{@@node} line, with the exception of the line for the `Top'
-node, must be followed by a line with a structuring command such as
-@code{@@chapter}, @code{@@section}, or
-@code{@@unnumberedsubsec}.@refill
-
-Each @code{@@node} line/structuring-command line combination
-must look either like this:@refill
-
-@example
-@group
-@@node Comments, Minimum, Conventions, Overview
-@@comment node-name, next, previous, up
-@@section Comments
-@end group
-@end example
-
-or like this (without the @code{@@comment} line):
-
-@example
-@group
-@@node Comments, Minimum, Conventions, Overview
-@@section Comments
-@end group
-@end example
-
-@noindent
-In this example, `Comments' is the name of both the node and the
-section. The next node is called `Minimum' and the previous node is
-called `Conventions'. The `Comments' section is within the `Overview'
-node, which is specified by the `Up' pointer. (Instead of an
-@code{@@comment} line, you can write an @code{@@ifinfo} line.)@refill
-
-If a file has a `Top' node, it must be called @samp{top} or @samp{Top}
-and be the first node in the file.@refill
-
-The menu updating commands create a menu of sections within a chapter,
-a menu of subsections within a section, and so on. This means that
-you must have a `Top' node if you want a menu of chapters.@refill
-
-Incidentally, the @code{makeinfo} command will create an Info file for
-a hierarchically organized Texinfo file that lacks `Next', `Previous'
-and `Up' pointers. Thus, if you can be sure that your Texinfo file
-will be formatted with @code{makeinfo}, you have no need for the
-`update node' commands. (@xref{Create an Info File, , Creating an
-Info File}, for more information about @code{makeinfo}.) However,
-both @code{makeinfo} and the @code{texinfo-format-@dots{}} commands
-require that you insert menus in the file.@refill

-@subsection Other Updating Commands
-
-In addition to the five major updating commands, Texinfo mode
-possesses several less frequently used updating commands:@refill
-
-@table @kbd
-@item M-x texinfo-insert-node-lines
-@findex texinfo-insert-node-lines
-Insert @code{@@node} lines before the @code{@@chapter},
-@code{@@section}, and other sectioning commands wherever they are
-missing throughout a region in a Texinfo file.@refill
-
-With an argument (@kbd{C-u} as prefix argument, if interactive), the
-@code{texinfo-insert-node-lines} command not only inserts
-@code{@@node} lines but also inserts the chapter or section titles as
-the names of the corresponding nodes. In addition, it inserts the
-titles as node names in pre-existing @code{@@node} lines that lack
-names. Since node names should be more concise than section or
-chapter titles, you must manually edit node names so inserted.@refill
-
-For example, the following marks a whole buffer as a region and inserts
-@code{@@node} lines and titles throughout:@refill
-
-@example
-C-x h C-u M-x texinfo-insert-node-lines
-@end example
-
-(Note that this command inserts titles as node names in @code{@@node}
-lines; the @code{texinfo-start-menu-description} command
-(@pxref{Inserting, Inserting Frequently Used Commands}) inserts titles
-as descriptions in menu entries, a different action. However, in both
-cases, you need to edit the inserted text.)@refill
-
-@item M-x texinfo-multiple-files-update
-@findex texinfo-multiple-files-update @r{(in brief)}
-Update nodes and menus in a document built from several separate files.
-With @kbd{C-u} as a prefix argument, create and insert a master menu in
-the outer file. With a numeric prefix argument, such as @kbd{C-u 2}, first
-update all the menus and all the `Next', `Previous', and `Up' pointers
-of all the included files before creating and inserting a master menu in
-the outer file. The @code{texinfo-multiple-files-update} command is

-every description in every menu in the region. However, this command
-does not indent the second and subsequent lines of a multi-line
-description.@refill
-
-@item M-x texinfo-sequential-node-update
-@findex texinfo-sequential-node-update
-Insert the names of the nodes immediately following and preceding the
-current node as the `Next' or `Previous' pointers regardless of those
-nodes' hierarchical level. This means that the `Next' node of a
-subsection may well be the next chapter. Sequentially ordered nodes are
-useful for novels and other documents that you read through
-sequentially. (However, in Info, the @code{g* @key{RET}} command lets

-@samp{\}, to mark the beginning of a command, just as Texinfo uses

-
-With these lines, you can format part of a Texinfo file for Info or

-
-A start-of-header line looks like this:@refill
-

-or @TeX{}, a Texinfo file must contain a line that looks like this:
-
-@example
-@@setfilename @var{info-file-name}
-@end example
-
-Write the @code{@@setfilename} command at the beginning of a line and
-follow it on the same line by the Info file name. Do not write
-anything else on the line; anything on the line after the command is
-considered part of the file name, including a comment.@refill
-
-The @code{@@setfilename} line specifies the name of the Info file to be
-generated. This name should be different from the name of the Texinfo
-file. There are two conventions for choosing the name: you can either
-remove the @samp{.tex} extension from the input file name, or replace it
-with the @samp{.info} extension.
-
-Some operating systems cannot handle long file names. You can run into
-a problem even when the file name you specify is itself short enough.
-This occurs because the Info formatters split a long Info file into
-short indirect subfiles, and name them by appending `-1', `-2', @dots{},
-`-10', `-11', and so on, to the original file name. (@xref{Tag and
-Split Files, , Tag Files and Split Files}.) The subfile name
-@file{texinfo.info-10}, for example, is too long for some systems; so
-the Info file name for this document is @file{texinfo} rather than
-@file{texinfo.info}.@refill
-
-The Info formatting commands ignore everything written before the
-@code{@@setfilename} line, which is why the very first line of
-the file (the @code{\input} line) does not need to be commented out.
-
-The @code{@@setfilename} line produces no output when you typeset a
-printed manual, but is does an essential job: it opens the index,
-cross-reference, and other auxiliary files used by Texinfo.

-
-Write the @code{@@settitle} command at the beginning of a line and
-follow it on the same line by the title. This tells @TeX{} the title
-to use in a header or footer. Do not write anything else on the line;
-anything on the line after the command is considered part of the
-title, including a comment.@refill
-
-Conventionally, when @TeX{} formats a Texinfo file for double-sided
-output, the title is printed in the left-hand (even-numbered) page
-headings and the current chapter title is printed in the right-hand
-(odd-numbered) page headings. (@TeX{} learns the title of each chapter
-from each @code{@@chapter} command.) Page footers are not
-printed.@refill
-
-Even if you are printing in a single-sided style, @TeX{} looks for an
-@code{@@settitle} command line, in case you include the manual title
-in the heading. @refill
-
-The @code{@@settitle} command should precede everything that generates
-actual output in @TeX{}.@refill
-
-Although the title in the @code{@@settitle} command is usually the
-same as the title on the title page, it does not affect the title as
-it appears on the title page. Thus, the two do not need not match

-page. (@xref{titlepage, , @code{@@titlepage}}.)@refill

-A manual's name and author are usually printed on a title page.
-Sometimes copyright information is printed on the title page as well;
-more often, copyright information is printed on the back of the title
-page.
-
-The title and copyright pages appear in the printed manual, but not in the
-Info file. Because of this, it is possible to use several slightly
-obscure @TeX{} typesetting commands that cannot be used in an Info file.
-In addition, this part of the beginning of a Texinfo file contains the text

-generate page headings.) All the material that you want to
-appear on unnumbered pages should be put between the
-@code{@@titlepage} and @code{@@end titlepage} commands. By using the
-@code{@@page} command you can force a page break within the region
-delineated by the @code{@@titlepage} and @code{@@end titlepage}
-commands and thereby create more than one unnumbered page. This is

-When you write a manual about a computer program, you should write the

-number@footnote{We have found that it is helpful to refer to versions
-of manuals as `editions' and versions of programs as `versions';
-otherwise, we find we are liable to confuse each other in conversation
-by referring to both the documentation and the software with the same

-is for which version of the program. (The `Top' node
-should also contain this information; see @ref{makeinfo top, ,
-@code{@@top}}.)@refill
-
-Texinfo provides two main methods for creating a title page. One method
-uses the @code{@@titlefont}, @code{@@sp}, and @code{@@center} commands
-to generate a title page in which the words on the page are
-centered.@refill
-
-The second method uses the @code{@@title}, @code{@@subtitle}, and
-@code{@@author} commands to create a title page with black rules under
-the title and author lines and the subtitle text set flush to the
-right hand side of the page. With this method, you do not specify any
-of the actual formatting of the title page. You specify the text
-you want, and Texinfo does the formatting. You may use either
-method.@refill
-
-@findex shorttitlepage
-For extremely simple applications, Texinfo also provides a command
-@code{@@shorttitlepage} which takes a single argument as the title.
-The argument is typeset on a page by itself and followed by a blank

-By international treaty, the copyright notice for a book should be

-
-When the copyright notice is on the back of the title page, that page

-on the copyright page should be within @code{@@titlepage} and
-@code{@@end titlepage} commands.@refill
-
-@findex vskip
-@findex filll
-@cindex Vertical whitespace (@samp{vskip})
-Use the @code{@@page} command to cause a page break. To push the

-@code{@@page} command that reads like this:@refill
-
-@example
-@@vskip 0pt plus 1filll
-@end example
-
-@noindent
-This is a @TeX{} command that is not supported by the Info formatting
-commands. The @code{@@vskip} command inserts whitespace. The
-@samp{0pt plus 1filll} means to put in zero points of mandatory whitespace,

-
-To repeat what is said elsewhere, Texinfo has two standard page heading

-(single-sided printing), and the other for documents which are printed on both

-
-@node headings on off, , end titlepage, Titlepage & Copyright Page
-@comment node-name, next, previous, up
-@subsection The @code{@@headings} Command
-@findex headings
-
-The @code{@@headings} command is rarely used. It specifies what kind of
-page headings and footings to print on each page. Usually, this is
-controlled by the @code{@@setchapternewpage} command. You need the
-@code{@@headings} command only if the @code{@@setchapternewpage} command
-does not do what you want, or if you want to turn off pre-defined page
-headings prior to defining your own. Write an @code{@@headings} command
-immediately after the @code{@@end titlepage} command.@refill
-
-You can use @code{@@headings} as follows:@refill
-
-@table @code
-@item @@headings off
-Turn off printing of page headings.@refill
-
-@item @@headings single
-Turn on page headings appropriate for single-sided printing.
-@refill
-
-@item @@headings double
-Turn on page headings appropriate for double-sided printing. The two
-commands, @code{@@headings on} and @code{@@headings double}, are
-synonymous.@refill
-
-@item @@headings singleafter
-@itemx @@headings doubleafter
-Turn on @code{single} or @code{double} headings, respectively, after the
-current page is output.
-
-@item @@headings on
-Turn on page headings: @code{single} if @samp{@@setchapternewpage
-on}, @code{double} otherwise.
-@end table
-
-For example, suppose you write @code{@@setchapternewpage off} before the
-@code{@@titlepage} command to tell @TeX{} to start a new chapter on the
-same page as the end of the last chapter. This command also causes
-@TeX{} to typeset page headers for single-sided printing. To cause
-@TeX{} to typeset for double sided printing, write @code{@@headings
-double} after the @code{@@end titlepage} command.
-
-You can stop @TeX{} from generating any page headings at all by
-writing @code{@@headings off} on a line of its own immediately after the
-line containing the @code{@@end titlepage} command, like this:@refill
-
-@example
-@@end titlepage
-@@headings off
-@end example
-
-@noindent
-The @code{@@headings off} command overrides the @code{@@end titlepage}
-command, which would otherwise cause @TeX{} to print page

-To print an index means to include it as part of a manual or Info
-file. This does not happen automatically just because you use
-@code{@@cindex} or other index-entry generating commands in the
-Texinfo file; those just cause the raw data for the index to be
-accumulated. To generate an index, you must include the
-@code{@@printindex} command at the place in the document where you
-want the index to appear. Also, as part of the process of creating a
-printed manual, you must run a program called @code{texindex}
-(@pxref{Format/Print Hardcopy}) to sort the raw data to produce a sorted
-index file. The sorted index file is what is actually used to
-print the index.@refill
-
-Texinfo offers six different types of predefined index: the concept
-index, the function index, the variables index, the keystroke index, the
-program index, and the data type index (@pxref{Predefined Indices}). Each
-index type has a two-letter name: @samp{cp}, @samp{fn}, @samp{vr},
-@samp{ky}, @samp{pg}, and @samp{tp}. You may merge indices, or put them
-into separate sections (@pxref{Combining Indices}); or you may define
-your own indices (@pxref{New Indices, , Defining New Indices}).@refill
-
-The @code{@@printindex} command takes a two-letter index name, reads
-the corresponding sorted index file and formats it appropriately into
-an index.@refill
-
-@ignore
-The two-letter index names are:
-
-@table @samp
-@item cp
-concept index

-function index
-@item vr
-variable index
-@item ky
-key index
-@item pg
-program index
-@item tp
-data type index
-@end table
-@end ignore
-The @code{@@printindex} command does not generate a chapter heading
-for the index. Consequently, you should precede the
-@code{@@printindex} command with a suitable section or chapter command
-(usually @code{@@unnumbered}) to supply the chapter heading and put
-the index into the table of contents. Precede the @code{@@unnumbered}

-A @dfn{node} is a segment of text that begins at an @code{@@node}
-command and continues until the next @code{@@node} command. The
-definition of node is different from that for chapter or section. A
-chapter may contain sections and a section may contain subsections;
-but a node cannot contain subnodes; the text of a node continues only
-until the next @code{@@node} command in the file. A node usually
-contains only one chapter structuring command, the one that follows
-the @code{@@node} line. On the other hand, in printed output nodes
-are used only for cross references, so a chapter or section may
-contain any number of nodes. Indeed, a chapter usually contains
-several nodes, one for each section, subsection, and
-subsubsection.@refill
-
-To create a node, write an @code{@@node} command at the beginning of a
-line, and follow it with four arguments, separated by commas, on the
-rest of the same line. These arguments are the name of the node, and
-the names of the `Next', `Previous', and `Up' pointers, in that order.
-You may insert spaces before each pointer if you wish; the spaces are
-ignored. You must write the name of the node, and the names of the
-`Next', `Previous', and `Up' pointers, all on the same line. Otherwise,
-the formatters fail. (@inforef{Top, info, info}, for more information
-about nodes in Info.)@refill
-
-Usually, you write one of the chapter-structuring command lines
-immediately after an @code{@@node} line---for example, an

-The name of a node identifies the node. The pointers enable

-Normally, a node's `Up' pointer contains the name of the node whose menu

-@cindex Writing an @code{@@node} line
-@cindex @code{@@node} line writing
-@cindex Node line writing
-
-The easiest way to write an @code{@@node} line is to write @code{@@node}
-at the beginning of a line and then the name of the node, like
-this:@refill
-
-@example
-@@node @var{node-name}
-@end example
-
-If you are using GNU Emacs, you can use the update node commands
-provided by Texinfo mode to insert the names of the pointers; or you
-can leave the pointers out of the Texinfo file and let @code{makeinfo}
-insert node pointers into the Info file it creates. (@xref{Texinfo
-Mode}, and @ref{makeinfo Pointer Creation}.)@refill
-
-Alternatively, you can insert the `Next', `Previous', and `Up'
-pointers yourself. If you do this, you may find it helpful to use the
-Texinfo mode keyboard command @kbd{C-c C-c n}. This command inserts
-@samp{@@node} and a comment line listing the names of the pointers in
-their proper order. The comment line helps you keep track of which
-arguments are for which pointers. This comment line is especially useful
-if you are not familiar with Texinfo.@refill
-
-The template for a node line with `Next', `Previous', and `Up' pointers
-looks like this:@refill
-
-@example
-@@node @var{node-name}, @var{next}, @var{previous}, @var{up}
-@end example
-
-If you wish, you can ignore @code{@@node} lines altogether in your first
-draft and then use the @code{texinfo-insert-node-lines} command to
-create @code{@@node} lines for you. However, we do not
-recommend this practice. It is better to name the node itself
-at the same time that you
-write a segment so you can easily make cross references. A large number
-of cross references are an especially important feature of a good Info
-file.@refill
-
-After you have inserted an @code{@@node} line, you should immediately
-write an @@-command for the chapter or section and insert its name.
-Next (and this is important!), put in several index entries. Usually,
-you will find at least two and often as many as four or five ways of
-referring to the node in the index. Use them all. This will make it
-much easier for people to find the node.@refill

-@item
-All the node names for a single Info file must be unique.@refill
-
-Duplicates confuse the Info movement commands. This means, for

-each summary node differently. You cannot just call each one
-``Summary''. You may, however, duplicate the titles of chapters, sections,

-called ``Summary'', so long as the node names for those sections are all
-different.@refill

-@cindex First node
-
-The first node of a Texinfo file is the `Top' node, except in an
-included file (@pxref{Include Files}).
-
-The `Top' node (which must be named @samp{top} or @samp{Top}) should
-have as its `Up' and `Previous' nodes the name of a node in another

-Info directory file, use @samp{(dir)} as the parent of the `Top' node;
-this is short for @samp{(dir)top}, and specifies the `Top' node in the
-@file{dir} file, which contains the main menu for Info. For example,

-@findex top @r{(@@-command)}
-
-A special sectioning command, @code{@@top}, has been created for use
-with the @code{@@node Top} line. The @code{@@top} sectioning command tells
-@code{makeinfo} that it marks the `Top' node in the file. It provides
-the information that @code{makeinfo} needs to insert node
-pointers automatically. Write the @code{@@top} command at the
-beginning of the line immediately following the @code{@@node Top}
-line. Write the title on the remaining part of the same line as the
-@code{@@top} command.@refill
-
-In Info, the @code{@@top} sectioning command causes the title to appear on a
-line by itself, with a line of asterisks inserted underneath.@refill
-
-In @TeX{} and @code{texinfo-format-buffer}, the @code{@@top}
-sectioning command is merely a synonym for @code{@@unnumbered}.
-Neither of these formatters require an @code{@@top} command, and do
-nothing special with it. You can use @code{@@chapter} or
-@code{@@unnumbered} after the @code{@@node Top} line when you use
-these formatters. Also, you can use @code{@@chapter} or
-@code{@@unnumbered} when you use the Texinfo updating commands to
-create or update pointers and menus.@refill
-
-@node Top Node Summary, , makeinfo top command, node
-@subsection The `Top' Node Summary
-@cindex @samp{@r{Top}} node summary
-
-You can help readers by writing a summary in the `Top' node, after the
-@code{@@top} line, before the main or master menu. The summary should
-briefly describe the document. In Info, this summary will appear just
-before the master menu. In a printed manual, this summary will appear
-on a page of its own.@refill
-
-If you do not want the summary to appear on a page of its own in a
-printed manual, you can enclose the whole of the `Top' node, including
-the @code{@@node Top} line and the @code{@@top} sectioning command line
-or other sectioning command line between @code{@@ifinfo} and @code{@@end
-ifinfo}. This prevents any of the text from appearing in the printed
-output. (@pxref{Conditionals, , Conditionally Visible Text}). You can
-repeat the brief description from the `Top' node within @code{@@iftex}
-@dots{} @code{@@end iftex} at the beginning of the first chapter, for
-those who read the printed manual. This saves paper and may look
-neater.@refill
-
-You should write the version number of the program to which the manual
-applies in the summary. This helps the reader keep track of which
-manual is for which version of the program. If the manual changes more
-frequently than the program or is independent of it, you should also
-include an edition number for the manual. (The title page should also
-contain this information: see @ref{titlepage, ,

-However, in any document, some information will be too detailed for

-need. For this reason, such creations should contain many cross

-
-In a printed manual, a cross reference results in a page reference,

-Texinfo has commands for indicating just what kind of object a piece of

-For example, in a printed manual,

-Use the @code{@@code} command to indicate text that is a piece of a
-program and which consists of entire syntactic tokens. Enclose the
-text in braces.@refill
-
-Thus, you should use @code{@@code} for an expression in a program, for
-the name of a variable or function used in a program, or for a
-keyword. Also, you should use @code{@@code} for the name of a
-program, such as @code{diff}, that is a name used in the machine. (You
-should write the name of a program in the ordinary text font if you
-regard it as a new English word, such as `Emacs' or `Bison'.)@refill
-
-Use @code{@@code} for environment variables such as @code{TEXINPUTS},
-and other variables.@refill
-
-Use @code{@@code} for command names in command languages that
-resemble programming languages, such as Texinfo or the shell.
-For example, @code{@@code} and @code{@@samp} are produced by writing
-@samp{@@code@{@@@@code@}} and @samp{@@code@{@@@@samp@}} in the Texinfo
-source, respectively.@refill
-
-Note, however, that you should not use @code{@@code} for shell options
-such as @samp{-c} when such options stand alone. (Use @code{@@samp}.)
-Also, an entire shell command often looks better if written using
-@code{@@samp} rather than @code{@@code}. In this case, the rule is to
-choose the more pleasing format.@refill
-
-It is incorrect to alter the case of a word inside an @code{@@code}
-command when it appears at the beginning of a sentence. Most computer
-languages are case sensitive. In C, for example, @code{Printf} is
-different from the identifier @code{printf}, and most likely is a
-misspelling of it. Even in languages which are not case sensitive, it
-is confusing to a human reader to see identifiers spelled in different
-ways. Pick one spelling and always use that. If you do not want to
-start a sentence with a command written all in lower case, you should
-rearrange the sentence.@refill
-
-Do not use the @code{@@code} command for a string of characters shorter
-than a syntactic token. If you are writing about @samp{TEXINPU}, which
-is just a part of the name for the @code{TEXINPUTS} environment
-variable, you should use @code{@@samp}.@refill
-
-In particular, you should not use the @code{@@code} command when writing
-about the characters used in a token; do not, for example, use
-@code{@@code} when you are explaining what letters or printable symbols
-can be used in the names of functions. (Use @code{@@samp}.) Also, you
-should not use @code{@@code} to mark text that is considered input to
-programs unless the input is written in a language that is like a
-programming language. For example, you should not use @code{@@code} for
-the keystroke commands of GNU Emacs (use @code{@@kbd} instead) although
-you may use @code{@@code} for the names of the Emacs Lisp functions that
-the keystroke commands invoke.@refill
-
-In the printed manual, @code{@@code} causes @TeX{} to typeset the
-argument in a typewriter face. In the Info file, it causes the Info
-formatting commands to use single quotation marks around the text.

-
-@noindent
-This defines @code{@@phoo} as a command that causes @TeX{} to typeset

-The first argument to @code{@@definfoenclose} is the @@-command name

-otherwise, the Info formatting commands will misinterpret the end
-delimiter string as a start delimiter string.@refill

-After you have defined @code{@@phoo} both for @TeX{} and for Info, you

-When you are making index entries, it is good practice to think of the
-different ways people may look for something. Different people
-@emph{do not} think of the same words when they look something up. A
-helpful index will have items indexed under all the different words
-that people may use. For example, one reader may think it obvious that
-the two-letter names for indices should be listed under ``Indices,
-two-letter names'', since the word ``Index'' is the general concept.
-But another reader may remember the specific concept of two-letter
-names and search for the entry listed as ``Two letter names for
-indices''. A good index will have both entries and will help both
-readers.@refill

-The data to make an index come from many individual indexing commands
-scattered throughout the Texinfo source file. Each command says to add
-one entry to a particular index; after formatting, the index will give
-the current page number or node name as the reference.@refill
-
-An index entry consists of an indexing command at the beginning of a
-line followed, on the rest of the line, by the entry.@refill

-the concept index:@refill

-for the concept index, @code{@@findex} for the function index, and so
-on.@refill
-
-@cindex Writing index entries
-@cindex Index entry writing
-Concept index entries consist of text. The best way to write an index
-is to choose entries that are terse yet clear. If you can do this,
-the index often looks better if the entries are not capitalized, but
-written just as they would appear in the middle of a sentence.
-(Capitalize proper names and acronyms that always call for upper case
-letters.) This is the case convention we use in most GNU manuals'
-indices.
-
-If you don't see how to make an entry terse yet clear, make it longer
-and clear---not terse and confusing. If many of the entries are several
-words long, the index may look better if you use a different convention:
-to capitalize the first word of each entry. But do not capitalize a
-case-sensitive name such as a C or Lisp function name or a shell
-command; that would be a spelling error.
-
-Whichever case convention you use, please use it consistently!
-
-@ignore
-Concept index entries consist of English text. The usual convention
-is to capitalize the first word of each such index entry, unless that
-word is the name of a function, variable, or other such entity that
-should not be capitalized. However, if your concept index entries are
-consistently short (one or two words each) it may look better for each
-regular entry to start with a lower case letter, aside from proper
-names and acronyms that always call for upper case letters. Whichever
-convention you adapt, please be consistent!
-@end ignore
-
-Entries in indices other than the concept index are symbol names in
-programming languages, or program names; these names are usually
-case-sensitive, so use upper and lower case as required for them.
-
-By default, entries for a concept index are printed in a small roman
-font and entries for the other indices are printed in a small
-@code{@@code} font. You may change the way part of an entry is
-printed with the usual Texinfo commands, such as @code{@@file} for
-file names and @code{@@emph} for emphasis (@pxref{Marking

-
-If you write several identical index entries in different places in a
-Texinfo file, the index in the printed manual will list all the pages to
-which those entries refer. However, the index in the Info file will
-list @strong{only} the node that references the @strong{first} of those
-index entries. Therefore, it is best to write indices in which each
-entry refers to only one place in the Texinfo file. Fortunately, this
-constraint is a feature rather than a loss since it means that the index
-will be easy to use. Otherwise, you could create an index that lists
-several pages for one entry and your reader would not know to which page
-to turn. If you have two identical entries for one topic, change the
-topics slightly, or qualify them to indicate the difference.@refill
-
-You are not actually required to use the predefined indices for their
-canonical purposes. For example, suppose you wish to index some C
-preprocessor macros. You could put them in the function index along
-with actual functions, just by writing @code{@@findex} commands for
-them; then, when you print the ``Function Index'' as an unnumbered
-chapter, you could give it the title `Function and Macro Index' and
-all will be consistent for the reader. Or you could put the macros in
-with the data types by writing @code{@@tindex} commands for them, and
-give that index a suitable title so the reader will understand.

-
-Sometimes you will want to combine two disparate indices such as functions
-and concepts, perhaps because you have few enough of one of them that
-a separate index for them would look silly.@refill
-
-You could put functions into the concept index by writing
-@code{@@cindex} commands for them instead of @code{@@findex} commands,
-and produce a consistent manual by printing the concept index with the
-title `Function and Concept Index' and not printing the `Function
-Index' at all; but this is not a robust procedure. It works only if
-your document is never included as part of another
-document that is designed to have a separate function index; if your
-document were to be included with such a document, the functions from
-your document and those from the other would not end up together.
-Also, to make your function names appear in the right font in the
-concept index, you would need to enclose every one of them between
-the braces of @code{@@code}.@refill

-In addition to the predefined indices, you may use the

-
-The name of an index should be a two letter word, such as @samp{au}.
-For example:@refill
-
-@example
-@@defindex au
-@end example
-
-This defines a new index, called the @samp{au} index. At the same
-time, it creates a new indexing command, @code{@@auindex}, that you
-can use to make index entries. Use the new indexing command just as
-you would use a predefined indexing command.@refill

-@@cindex kinesthetic image schemas
-@@auindex Johnson, Mark
-@@auindex Lakoff, George
-@end example
-

-(Evidently, @samp{au} serves here as an abbreviation for ``author''.)
-Texinfo constructs the new indexing command by concatenating the name
-of the index with @samp{index}; thus, defining an @samp{au} index
-leads to the automatic creation of an @code{@@auindex} command.@refill
-
-Use the @code{@@printindex} command to print the index, as you do with
-the predefined indices. For example:@refill

-
-Occasionally, you may want to actually insert several consecutive

-command, write the @code{@@deffn} command at the beginning of a line
-and follow it on the same line by the category of the entity, the name

-of the definition on succeeding lines. (You may embed examples in the
-body.) Finally, end the definition with an @code{@@end deffn} command
-written on a line of its own. (The other definition commands follow
-the same format.)@refill

-belongs. The @code{@@deffn} command possesses three predefined,
-specialized variations, @code{@@defun}, @code{@@defmac}, and

-``Macro'', and ``Special Form'' respectively. The @code{@@defvr}

-The @code{@@deffn} command is the general definition command for

-names as metasyntactic variables---they stand for the actual argument
-values. Within the text of the description, write an argument name
-explicitly with @code{@@var} to refer to the value of the argument. In
-the example above, we used @samp{@@var@{nchars@}} in this way.

-Sometimes it is useful to distinguish methods and @dfn{operations}.
-You can think of an operation as the specification for a method.
-Thus, a window system might specify that all window classes have a
-method named @code{expose}; we would say that this window system
-defines an @code{expose} operation on windows in general. Typically,
-the operation has a name and also specifies the pattern of arguments;
-all methods that implement the operation must accept the same
-arguments, since applications that use the operation do so without

-
-Often it makes more sense to document operations than methods. For
-example, window application developers need to know about the
-@code{expose} operation, but need not be concerned with whether a

-
-@example
-@@footnote@{@var{text}@}

-Footnotes may be of any length, but are usually short.@refill

-the problem, move the footnote into the body text of the table.

-In a printed manual or book, the reference mark for a footnote is a
-small, superscripted number; the text of the footnote appears at the

-In the `End' node style, all the footnotes for a single node
-are placed at the end of that node. The footnotes are separated from

-@samp{Footnotes} within it. Each footnote begins with an
-@samp{(@var{n})} reference mark.@refill

-node are placed in an automatically constructed node of
-their own. In this style, a ``footnote reference'' follows
-each @samp{(@var{n})} reference mark in the body of the

-which you use to reach the footnote node.@refill
-
-The name of the node containing the footnotes is constructed
-by appending @w{@samp{-Footnotes}} to the name of the node
-that contains the footnotes. (Consequently, the footnotes'

-separate node style, you would use the following shell command:@refill
-

-To format the Texinfo manual in the end of node style, you would

-commands do @emph{not} format the text.
-
-Use the @code{@@set @var{flag}} command to turn on, or @dfn{set}, a

-In the example, the formatting commands will format the text between
-@code{@@ifset large} and @code{@@end ifset} because the @code{large}
-flag is set.@refill
-
-@findex clear
-Use the @code{@@clear @var{flag}} command to turn off, or @dfn{clear},
-a flag. Clearing a flag is the opposite of setting a flag. The
-command looks like this:@refill
-
-@example
-@@clear @var{flag}
-@end example
-
-@noindent
-Write the command on a line of its own.
-
-When @var{flag} is cleared, the Texinfo formatting commands do
-@emph{not} format the text between @code{@@ifset @var{flag}} and
-@code{@@end ifset}; that text is ignored and does not appear in either
-printed or Info output.@refill
-
-For example, if you clear the flag of the preceding example by writing
-an @code{@@clear large} command after the @code{@@set large} command
-(but before the conditional text), then the Texinfo formatting commands
-ignore the text between the @code{@@ifset large} and @code{@@end ifset}
-commands. In the formatted output, that text does not appear; in both

-@node value, value Example, ifset ifclear, set clear value
-@subsection @code{@@value}
-@findex value
-
-You can use the @code{@@set} command to specify a value for a flag,
-which is expanded by the @code{@@value} command. The value is a string
-a characters.
-
-Write the @code{@@set} command like this:
-
-@example
-@@set foo This is a string.
-@end example
-
-@noindent
-This sets the value of @code{foo} to ``This is a string.''
-
-The Texinfo formatters replace an @code{@@value@{@var{flag}@}} command with
-the string to which @var{flag} is set.@refill
-
-Thus, when @code{foo} is set as shown above, the Texinfo formatters convert
-
-@example
-@group
-@@value@{foo@}
-@exdent @r{to}
-This is a string.
-@end group
-@end example
-
-You can write an @code{@@value} command within a paragraph; but you
-must write an @code{@@set} command on a line of its own.
-
-If you write the @code{@@set} command like this:
-
-@example
-@@set foo
-@end example
-
-@noindent
-without specifying a string, the value of @code{foo} is an empty string.
-
-If you clear a previously set flag with an @code{@@clear @var{flag}}
-command, a subsequent @code{@@value@{flag@}} command is invalid and the
-string is replaced with an error message that says @samp{@{No value for
-"@var{flag}"@}}.
-
-For example, if you set @code{foo} as follows:@refill
-
-@example
-@@set how-much very, very, very
-@end example
-
-@noindent
-then the formatters transform
-
-@example

-You use the Texinfo @code{@@macro} command to define a macro. For example:
-
-@example
-@@macro @var{macro-name}@{@var{param1}, @var{param2}, @dots{}@}
-@var{text} @dots{} \@var{param1}\ @dots{}
-@@end macro
-@end example
-
-The @dfn{parameters} @var{param1}, @var{param2}, @dots{} correspond to
-arguments supplied when the macro is subsequently used in the document
-(see the next section).
-
-If a macro needs no parameters, you can define it either with an empty
-list (@samp{@@macro foo @{@}}) or with no braces at all (@samp{@@macro
-foo}).
-
-@cindex Body of a macro
-@cindex Mutually recursive macros
-@cindex Recursion, mutual
-The definition or @dfn{body} of the macro can contain any Texinfo
-commands, including previously-defined macros. (It is not possible to
-have mutually recursive Texinfo macros.) In the body, instances of a
-parameter name surrounded by backslashes, as in @samp{\@var{param1}\} in
-the example above, are replaced by the corresponding argument from the
-macro invocation.

-@cindex Macros, undefining
-@cindex Undefining macros
-You can undefine a macro @var{foo} with @code{@@unmacro @var{foo}}.

-@end example
-
-
-@node Invoking Macros, , Defining Macros, Macros

-After a macro is defined (see the previous section), you can use
-(@dfn{invoke}) it in your document like this:
-
-@example
-@@@var{macro-name} @{@var{arg1}, @var{arg2}, @dots{}@}
-@end example
-
-@noindent and the result will be just as if you typed the body of
-@var{macro-name} at that spot. For example:
-
-@example
-@@macro foo @{p, q@}
-Together: \p\ & \q\.
-@@end macro
-@@foo@{a, b@}
-@end example
-
-@noindent produces:
-
-@display
-Together: a & b.
-@end display
-
-@cindex Backslash, and macros
-Thus, the arguments and parameters are separated by commas and delimited
-by braces; any whitespace after (but not before) a comma is ignored. To
-insert a comma, brace, or backslash in an argument, prepend a backslash,
-as in
-
-@example
-@@@var{macro-name} @{\\\@{\@}\,@}
-@end example
-
-@noindent
-which will pass the (almost certainly error-producing) argument
-@samp{\@{@},} to @var{macro-name}.
-
-If the macro is defined to take a single argument, and is invoked
-without any braces, the entire rest of the line after the macro name is
-supplied as the argument. For example:
-
-@example
-@@macro bar @{p@}
-Twice: \p\, \p\.
-@@end macro
-@@bar aah
-@end example
-

-file) can be printed on a wide variety of printers.@refill

-@TeX{}. (The @code{texi2dvi} command automatically generates indices;
-see @ref{Format with texi2dvi, , Format using @code{texi2dvi}}.) To
-generate a printed index after running the @code{tex} command, you first

-The @code{tex} formatting command outputs unsorted index files under
-names that obey a standard convention. These names are the name of
-your main input file to the @code{tex} formatting command, with
-everything after the first period thrown away, and the two letter
-names of indices added at the end. For example, the raw index output
-files for the input file @file{foo.texinfo} would be @file{foo.cp},
-@file{foo.vr}, @file{foo.fn}, @file{foo.tp}, @file{foo.pg} and
-@file{foo.ky}. Those are exactly the arguments to give to

-or @code{@@defcodeindex}. (You may execute @samp{texindex foo.??}
-even if there are similarly named files with two letter extensions
-that are not index files, such as @samp{foo.el}. The @code{texindex}
-command reports but otherwise ignores such files.)@refill
-
-For each file specified, @code{texindex} generates a sorted index file
-whose name is made by appending @samp{s} to the input file name. The
-@code{@@printindex} command knows to look for a file of that name.
-@code{texindex} does not alter the raw index output file.@refill
-
-After you have sorted the indices, you need to rerun the @code{tex}
-formatting command on the Texinfo file. This regenerates a formatted
-@sc{dvi} file with up-to-date index entries.@footnote{If you use more
-than one index and have cross references to an index other than the
-first, you must run @code{tex} @emph{three times} to get correct output:
-once to generate raw index data; again (after @code{texindex}) to output
-the text of the indices and determine their true page numbers; and a
-third time to output correct page numbers in cross references to them.
-However, cross references to indices are rare.}@refill
-
-To summarize, this is a three step process:
-
-@enumerate
-@item
-Run the @code{tex} formatting command on the Texinfo file. This
-generates the formatted @sc{dvi} file as well as the raw index files
-with two letter extensions.@refill
-
-@item
-Run the shell command @code{texindex} on the raw index files to sort
-them. This creates the corresponding sorted index files.@refill
-
-@item
-Rerun the @code{tex} formatting command on the Texinfo file. This
-regenerates a formatted @sc{dvi} file with the index entries in the
-correct order. This second run also corrects the page numbers for
-the cross references. (The tables of contents are always correct.)@refill
-@end enumerate
-
-You need not run @code{texindex} each time after you run the
-@code{tex} formatting. If you do not, on the next run, the @code{tex}
-formatting command will use whatever sorted index files happen to
-exist from the previous use of @code{texindex}. This is usually

-bytes, @code{texinfo-format-buffer} and @code{makeinfo} split the
-large Info file into shorter @dfn{indirect} subfiles of about 50,000
-bytes each. Big files are split into smaller files so that Emacs does
-not need to make a large buffer to hold the whole of a large Info
-file; instead, Emacs allocates just enough memory for the small, split
-off file that is needed at the time. This way, Emacs avoids wasting
-memory when you run Info. (Before splitting was implemented, Info
-files were always kept short and @dfn{include files} were designed as
-a way to create a single, large printed manual out of the smaller Info
-files. @xref{Include Files}, for more information. Include files are
-still used for very large documents, such as @cite{The Emacs Lisp
-Reference Manual}, in which each chapter is a separate file.)@refill

-When a file is split, Info itself makes use of a shortened version of
-the original file that contains just the tag table and references to
-the files that were split off. The split off files are called

-The split off files have names that are created by appending @w{@samp{-1}},

-specify the `Top' node, since Info goes to the `Top' node if no node
-name is mentioned. @xref{Other Info Files, , Nodes in Other Info

-
-Thus, the @samp{Info} entry points to the `Top' node of the

-of the @file{emacs} file.@refill

-The first part of the menu entry is the menu entry name, followed by a
-colon. The second part is the name of the Info file, in parentheses,
-followed by a period. The third part is the description.
-
-The name of an Info file often has a @file{.info} extension. Thus, the
-Info file for GDB might be called either @file{gdb} or @file{gdb.info}.
-The Info reader programs automatically try the file name both with and
-without @file{.info}; so it is better to avoid clutter and not to write

-
-@cindex Tips
-@cindex Usage tips
-@cindex Hints
-@itemize @bullet
-@item
-Write in the present tense, not in the past or the future.
-
-@item
-Write actively! For example, write ``We recommend that @dots{}'' rather
-than ``It is recommended that @dots{}''.
-
-@item
-Use 70 or 72 as your fill column. Longer lines are hard to read.
-
-@item
-Include a copyright notice and copying permissions.
-@end itemize
-
-@subsubheading Index, index, index!
-
-Write many index entries, in different ways.
-Readers like indices; they are helpful and convenient.
-
-Although it is easiest to write index entries as you write the body of
-the text, some people prefer to write entries afterwards. In either
-case, write an entry before the paragraph to which it applies. This
-way, an index entry points to the first page of a paragraph that is
-split across pages.
-
-Here are more hints we have found valuable:
-
-@itemize @bullet
-@item
-Write each index entry differently, so each entry refers to a different
-place in the document.
-
-@item
-Write index entries only where a topic is discussed significantly. For
-example, it is not useful to index ``debugging information'' in a
-chapter on reporting bugs. Someone who wants to know about debugging
-information will certainly not find it in that chapter.
-
-@item
-Consistently capitalize the first word of every concept index entry,
-or else consistently use lower case. Terse entries often call for
-lower case; longer entries for capitalization. Whichever case
-convention you use, please use one or the other consistently! Mixing
-the two styles looks bad.
-
-@item
-Always capitalize or use upper case for those words in an index for
-which this is proper, such as names of countries or acronyms. Always
-use the appropriate case for case-sensitive names, such as those in C or
-Lisp.
-
-@item
-Write the indexing commands that refer to a whole section immediately
-after the section command, and write the indexing commands that refer to
-the paragraph before the paragraph.
-
-@need 1000
-In the example that follows, a blank line comes after the index
-entry for ``Leaping'':
-
-@example
-@group
-@@section The Dog and the Fox
-@@cindex Jumping, in general
-@@cindex Leaping
-
-@@cindex Dog, lazy, jumped over
-@@cindex Lazy dog jumped over
-@@cindex Fox, jumps over dog
-@@cindex Quick fox jumps over dog
-The quick brown fox jumps over the lazy dog.
-@end group
-@end example
-
-@noindent
-(Note that the example shows entries for the same concept that are
-written in different ways---@samp{Lazy dog}, and @samp{Dog, lazy}---so
-readers can look up the concept in different ways.)
-@end itemize
-
-@subsubheading Blank lines
-
-@itemize @bullet
-@item
-Insert a blank line between a sectioning command and the first following
-sentence or paragraph, or between the indexing commands associated with
-the sectioning command and the first following sentence or paragraph, as
-shown in the tip on indexing. Otherwise, a formatter may fold title and
-paragraph together.
-
-@item
-Always insert a blank line before an @code{@@table} command and after an
-@code{@@end table} command; but never insert a blank line after an
-@code{@@table} command or before an @code{@@end table} command.
-
-@need 1000
-For example,
-
-@example
-@group
-Types of fox:
-

-Also jump over lazy dogs.

-@@noindent
-On the other hand, @dots{}
-@end group
-@end example
-
-Insert blank lines before and after @code{@@itemize} @dots{} @code{@@end
-itemize} and @code{@@enumerate} @dots{} @code{@@end enumerate} in the
-same way.
-@end itemize
-
-@subsubheading Complete phrases
-
-Complete phrases are easier to read than @dots{}
-
-@itemize @bullet
-@item
-Write entries in an itemized list as complete sentences; or at least, as
-complete phrases. Incomplete expressions @dots{} awkward @dots{} like
-this.
-
-@item
-Write the prefatory sentence or phrase for a multi-item list or table as
-a complete expression. Do not write ``You can set:''; instead, write
-``You can set these variables:''. The former expression sounds cut off.
-@end itemize
-
-@subsubheading Editions, dates and versions
-
-Write the edition and version numbers and date in three places in every
-manual:
-
-@enumerate
-@item
-In the first @code{@@ifinfo} section, for people reading the Texinfo file.
-
-@item
-In the @code{@@titlepage} section, for people reading the printed manual.
-
-@item
-In the `Top' node, for people reading the Info file.

-Also, it helps to write a note before the first @code{@@ifinfo}

-@subsubheading Definition Commands
-

-a uniform format.@refill
-
-@itemize @bullet
-@item
-Write just one definition command for each entity you define with a

-Use @code{@@table} @dots{} @code{@@end table} in an appendix that

-
-@example
-@group
- @@kbd@{C-x v@}
- @@kbd@{M-x vc-next-action@}
- Perform the next logical operation
- on the version-controlled file
- corresponding to the current buffer.
-@end group
-@end example
-
-@need 950
-@noindent
-so it looks like this:
-
-@iftex

- @kbd{C-x v}
- @kbd{M-x vc-next-action}
- Perform the next logical operation on the version-controlled file

-@quotation
-`C-x v' `M-x vc-next-action' Perform the next logical operation on the

-@end quotation
-@end ifinfo
-
-@noindent
-In this case, the text should be formatted with
-@code{@@table}, @code{@@item}, and @code{@@itemx}, to create a table.
-
-@subsubheading @@code, @@samp, @@var, and @samp{---}
-
-@itemize @bullet
-@item
-Use @code{@@code} around Lisp symbols, including command names.
-For example,
-
-@example
-The main function is @@code@{vc-next-action@}, @dots{}
-@end example
-
-@item
-Avoid putting letters such as @samp{s} immediately after an
-@samp{@@code}. Such letters look bad.
-
-@item
-Use @code{@@var} around meta-variables. Do not write angle brackets
-around them.
-
-@item
-Use three hyphens in a row, @samp{---}, to indicate a long dash. @TeX{}
-typesets these as a long dash and the Info formatters reduce three
-hyphens to two.
-@end itemize
-
-@subsubheading Periods Outside of Quotes
-
-Place periods and other punctuation marks @emph{outside} of quotations,
-unless the punctuation is part of the quotation. This practice goes
-against publishing conventions in the United States, but enables the
-reader to distinguish between the contents of the quotation and the
-whole passage.
-
-For example, you should write the following sentence with the period
-outside the end quotation marks:
-
-@example
-Evidently, @samp{au} is an abbreviation for ``author''.
-@end example
-
-@noindent
-since @samp{au} does @emph{not} serve as an abbreviation for
-@samp{author.} (with a period following the word).
-
-@subsubheading Introducing New Terms
-
-@itemize @bullet
-@item
-Introduce new terms so that a reader who does not know them can
-understand them from context; or write a definition for the term.
-
-For example, in the following, the terms ``check in'', ``register'' and
-``delta'' are all appearing for the first time; the example sentence should be
-rewritten so they are understandable.
-
-@quotation
-The major function assists you in checking in a file to your
-version control system and registering successive sets of changes to
-it as deltas.
-@end quotation
-
-@item
-Use the @code{@@dfn} command around a word being introduced, to indicate
-that the reader should not expect to know the meaning already, and
-should expect to learn the meaning from this passage.
-@end itemize
-
-@subsubheading @@pxref
-
-@c !!! maybe include this in the tips on pxref
-@ignore
-By the way, it is okay to use pxref with something else in front of
-it within the parens, as long as the pxref is followed by the close
-paren, and the material inside the parens is not part of a larger
-sentence. Also, you can use xref inside parens as part of a complete
-sentence so long as you terminate the cross reference with punctuation.
-@end ignore
-Absolutely never use @code{@@pxref} except in the special context for
-which it is designed: inside parentheses, with the closing parenthesis
-following immediately after the closing brace. One formatter
-automatically inserts closing punctuation and the other does not. This
-means that the output looks right both in printed output and in an Info
-file, but only when the command is used inside parentheses.
-
-@subsubheading Invoking from a Shell
-
-You can invoke programs such as Emacs, GCC, and GAWK from a shell.
-The documentation for each program should contain a section that
-describes this. Unfortunately, if the node names and titles for these
-sections are all different, readers find it hard to search for the
-section.@refill
-
-Name such sections with a phrase beginning with the word
-@w{`Invoking @dots{}'}, as in `Invoking Emacs'; this way
-users can find the section easily.
-
-@subsubheading @sc{ansi c} Syntax
-
-When you use @code{@@example} to describe a C function's calling
-conventions, use the @sc{ansi c} syntax, like this:@refill
-
-@example
-void dld_init (char *@@var@{path@});
-@end example
-
-@noindent
-And in the subsequent discussion, refer to the argument values by
-writing the same argument names, again highlighted with
-@code{@@var}.@refill
-
-@need 800
-Avoid the obsolete style that looks like this:@refill
-
-@example
-#include <dld.h>
-
-dld_init (path)
-char *path;
-@end example
-
-Also, it is best to avoid writing @code{#include} above the
-declaration just to indicate that the function is declared in a
-header file. The practice may give the misimpression that the
-@code{#include} belongs near the declaration of the function. Either
-state explicitly which header file holds the declaration or, better
-yet, name the header file used for a group of functions at the
-beginning of the section that describes the functions.@refill
-
-@subsubheading Bad Examples
-
-Here are several examples of bad writing to avoid:
-
-In this example, say, `` @dots{} you must @code{@@dfn}@{check
-in@} the new version.'' That flows better.
-
-@quotation
-When you are done editing the file, you must perform a
-@code{@@dfn}@{check in@}.
-@end quotation
-
-In the following example, say, ``@dots{} makes a unified interface such as VC
-mode possible.''
-
-@quotation
-SCCS, RCS and other version-control systems all perform similar
-functions in broadly similar ways (it is this resemblance which makes
-a unified control mode like this possible).
-@end quotation
-
-And in this example, you should specify what `it' refers to:
-
-@quotation
-If you are working with other people, it assists in coordinating
-everyone's changes so they do not step on each other.
-@end quotation
-
-@subsubheading And Finally @dots{}
-
-@itemize @bullet
-@item
-Pronounce @TeX{} as if the @samp{X} were a Greek `chi', as the last
-sound in the name `Bach'. But pronounce Texinfo as in `speck':
-@samp{teckinfo}.
-
-@item
-Write notes for yourself at the very end of a Texinfo file after the

-To include another file within a Texinfo file, write the

-the same line by the name of a file to be included. For
-example:@refill
-
-@example
-@@include buffers.texi
-@end example
-
-An included file should simply be a segment of text that you expect to
-be included as is into the overall or @dfn{outer} Texinfo file; it
-should not contain the standard beginning and end parts of a Texinfo
-file. In particular, you should not start an included file with a
-line saying @samp{\input texinfo}; if you do, that phrase is inserted
-into the output file as is. Likewise, you should not end an included
-file with an @code{@@bye} command; nothing after @code{@@bye} is
-formatted.@refill
-
-In the past, you were required to write an @code{@@setfilename} line at the
-beginning of an included file, but no longer. Now, it does not matter
-whether you write such a line. If an @code{@@setfilename} line exists
-in an included file, it is ignored.@refill
-
-Conventionally, an included file begins with an @code{@@node} line that
-is followed by an @code{@@chapter} line. Each included file is one
-chapter. This makes it easy to use the regular node and menu creating
-and updating commands to create the node pointers and menus within the
-included file. However, the simple Emacs node and menu creating and
-updating commands do not work with multiple Texinfo files. Thus you
-cannot use these commands to fill in the `Next', `Previous', and `Up'
-pointers of the @code{@@node} line that begins the included file. Also,
-you cannot use the regular commands to create a master menu for the
-whole file. Either you must insert the menus and the `Next',
-`Previous', and `Up' pointers by hand, or you must use the GNU Emacs
-Texinfo mode command, @code{texinfo-multiple-files-update}, that is

-When Info was first created, it was customary to create many small
-Info files on one subject. Each Info file was formatted from its own
-Texinfo source file. This custom meant that Emacs did not need to
-make a large buffer to hold the whole of a large Info file when
-someone wanted information; instead, Emacs allocated just enough
-memory for the small Info file that contained the particular
-information sought. This way, Emacs could avoid wasting memory.@refill
-
-References from one file to another were made by referring to the file
-name as well as the node name. (@xref{Other Info Files, , Referring to
-Other Info Files}. Also, see @ref{Four and Five Arguments, ,
-@code{@@xref} with Four and Five Arguments}.)@refill
-
-Include files were designed primarily as a way to create a single,
-large printed manual out of several smaller Info files. In a printed
-manual, all the references were within the same document, so @TeX{}
-could automatically determine the references' page numbers. The Info
-formatting commands used include files only for creating joint
-indices; each of the individual Texinfo files had to be formatted for
-Info individually. (Each, therefore, required its own
-@code{@@setfilename} line.)@refill
-
-However, because large Info files are now split automatically, it is
-no longer necessary to keep them small.@refill
-
-Nowadays, multiple Texinfo files are used mostly for large documents,
-such as @cite{The GNU Emacs Lisp Reference Manual}, and for projects
-in which several different people write different sections of a
-document simultaneously.@refill
-
-In addition, the Info formatting commands have been extended to work
-with the @code{@@include} command so as to create a single large Info
-file that is split into smaller files if necessary. This means that
-you can write menus and cross references without naming the different
-Texinfo files.@refill

-Texinfo provides two standard heading formats, one for manuals printed

-on both sides of the paper.
-
-By default, nothing is specified for the footing of a Texinfo file,

-
-The standard format for single-sided printing consists of a header
-line in which the left-hand part contains the name of the chapter, the
-central part is blank, and the right-hand part contains the page
-number.@refill
-
-@need 950
-A single-sided page looks like this:

-The standard format for two-sided printing depends on whether the page
-number is even or odd. By convention, even-numbered pages are on the
-left- and odd-numbered pages are on the right. (@TeX{} will adjust the
-widths of the left- and right-hand margins. Usually, widths are
-correct, but during double-sided printing, it is wise to check that
-pages will bind properly---sometimes a printer will produce output in
-which the even-numbered pages have a larger right-hand margin than the
-odd-numbered pages.)@refill
-
-In the standard double-sided format, the left part of the left-hand
-(even-numbered) page contains the page number, the central part is
-blank, and the right part contains the title (specified by the

-(odd-numbered) page contains the name of the chapter, the central part

-Texinfo provides six commands for specifying headings and
-footings. The @code{@@everyheading} command and
-@code{@@everyfooting} command generate page headers and footers
-that are the same for both even- and odd-numbered pages.
-The @code{@@evenheading} command and @code{@@evenfooting}

-(left-hand) pages; and the @code{@@oddheading} command and
-@code{@@oddfooting} command generate headers and footers for
-odd-numbered (right-hand) pages.@refill
-
-Write custom heading specifications in the Texinfo file immediately

-between @code{@@iftex} and @code{@@end iftex} commands since the

-@code{makeinfo-buffer}) to format your file and check for other

-After you have written part of a Texinfo file, you can use the

-see whether the region formats properly.@refill
-
-Most likely, however, you are reading this section because for some

-
-If you have made a mistake with an @@-command,
-@code{texinfo-format-region} will stop processing at or after the
-error and display an error message. To see where in the buffer the
-error occurred, switch to the @samp{*Info Region*} buffer; the cursor
-will be in a position that is after the location of the error. Also,
-the text will not be formatted after the place where the error
-occurred (or more precisely, where it was detected).@refill

-For example, if you accidentally end a menu with the command @code{@@end

-will see an error message that says:@refill

-odd error messages. For example, the following cross reference fails to format:@refill
-
-@example
-(@@xref@{Catching Mistakes, for more info.)
-@end example
-
-@noindent
-In this case, @code{texinfo-format-region} detects the missing closing
-brace but displays a message that says @samp{Unbalanced parentheses}
-rather than @samp{Unbalanced braces}. This is because the formatting
-command looks for mismatches between braces as if they were
-parentheses.@refill
-
-Sometimes @code{texinfo-format-region} fails to detect mistakes. For
-example, in the following, the closing brace is swapped with the
-closing parenthesis:@refill
-

-
-@example
-(*Note Catching Mistakes::, for more info.)
-@end example
-
-Incidentally, if you are reading this node in Info and type @kbd{f
-@key{RET}} (@code{Info-follow-reference}), you will generate an error
-message that says:
-
-@example
-No such node: "Catching Mistakes) The only way @dots{}
-@end example
-
-@noindent
-This is because Info perceives the example of the error as the first
-cross reference in this node and if you type a @key{RET} immediately
-after typing the Info @kbd{f} command, Info will attempt to go to the
-referenced node. If you type @kbd{f catch @key{TAB} @key{RET}}, Info
-will complete the node name of the correctly written example and take
-you to the `Catching Mistakes' node. (If you try this, you can return

-@samp{@@par} is an internal @TeX{} command of no relevance to Texinfo.
-@samp{l.27} means that @TeX{} detected the problem on line 27 of the

-circumstance.@refill
-
-Unfortunately, @TeX{} is not always so helpful, and sometimes you must

-
-In any case, if you run into a problem like this, you can do one of three

-@item
-You can tell @TeX{} to continue running and ignore just this error by

-it can by typing @kbd{r @key{RET}} at the @samp{?} prompt.@refill
-
-This is often the best thing to do. However, beware: the one error
-may produce a cascade of additional error messages as its consequences
-are felt through the rest of the file. (To stop @TeX{} when it is
-producing such an avalanche of error messages, type @kbd{C-d} (or
-@kbd{C-c C-d}, if you are running a shell inside Emacs.))@refill
-
-@item
-You can tell @TeX{} to stop this run by typing @kbd{x @key{RET}}
-at the @samp{?} prompt.@refill
-@end enumerate
-
-Please note that if you are running @TeX{} inside Emacs, you need to
-switch to the shell buffer and line at which @TeX{} offers the @samp{?}
-prompt.@refill
-
-Sometimes @TeX{} will format a file without producing error messages even
-though there is a problem. This usually occurs if a command is not ended
-but @TeX{} is able to continue processing anyhow. For example, if you fail
-to end an itemized list with the @code{@@end itemize} command, @TeX{} will
-write a @sc{dvi} file that you can print out. The only error message that
-@TeX{} will give you is the somewhat mysterious comment that@refill
-
-@example
-(@@end occurred inside a group at level 1)
-@end example
-
-@noindent
-However, if you print the @sc{dvi} file, you will find that the text
-of the file that follows the itemized list is entirely indented as if
-it were part of the last item in the itemized list. The error message
-is the way @TeX{} says that it expected to find an @code{@@end}
-command somewhere in the file; but that it could not determine where
-it was needed.@refill
-
-Another source of notoriously hard-to-find errors is a missing
-@code{@@end group} command. If you ever are stumped by
-incomprehensible errors, look for a missing @code{@@end group} command
-first.@refill
-
-If the Texinfo file lacks header lines,
-@TeX{} may stop in the
-beginning of its run and display output that looks like the following.
-The @samp{*} indicates that @TeX{} is waiting for input.@refill
-
-@example
-This is TeX, Version 3.14159 (Web2c 7.0)
-(test.texinfo [1])
-*
-@end example
-
-@noindent
-In this case, simply type @kbd{\end @key{RET}} after the asterisk. Then
-write the header lines in the Texinfo file and run the @TeX{} command
-again. (Note the use of the backslash, @samp{\}. @TeX{} uses @samp{\}

-When you invoke the @code{texinfo-show-structure} command, Emacs will

-If your file is valid, you will receive a message that says ``File appears
-valid''. However, if you have a pointer that does not point to a node,
-error messages will be displayed in a buffer called @samp{*problems in
-info file*}.@refill
-
-For example, @code{Info-validate} was run on a test file that contained
-only the first node of this manual. One of the messages said:@refill
-
-@example
-In node "Overview", invalid Next: Texinfo Mode
-@end example
-
-@noindent
-This meant that the node called @samp{Overview} had a `Next' pointer that
-did not point to anything (which was true in this case, since the test file
-had only one node in it).@refill
-
-Now suppose we add a node named @samp{Texinfo Mode} to our test case
-but we do not specify a `Previous' for this node. Then we will get
-the following error message:@refill
-
-@example
-In node "Texinfo Mode", should have Previous: Overview
-@end example
-
-@noindent
-This is because every `Next' pointer should be matched by a
-`Previous' (in the node where the `Next' points) which points back.@refill
-
-@code{Info-validate} also checks that all menu entries and cross references
-point to actual nodes.@refill
-
-Note that @code{Info-validate} requires a tag table and does not work
-with files that have been split. (The @code{texinfo-format-buffer}
-command automatically splits large files.) In order to use
-@code{Info-validate} on a large file, you must run
-@code{texinfo-format-buffer} with an argument so that it does not split
-the Info file; and you must create a tag table for the unsplit
-file.@refill

-You can run @code{Info-validate} only on a single Info file that has a
-tag table. The command will not work on the indirect subfiles that
-are generated when a master file is split. If you have a large file
-(longer than 70,000 bytes or so), you need to run the

-to create a tag table for the Info file. After you have done this,
-you can run @code{Info-validate} and look for badly referenced
-nodes.@refill
-
-The first step is to create an unsplit Info file. To prevent
-@code{texinfo-format-buffer} from splitting a Texinfo file into
-smaller Info files, give a prefix to the @kbd{M-x

-
-@example

-@end example
-
-@noindent
-(Note the upper case @samp{I} in @code{Info-tagify}.) This creates an

-for you automatically. (Generally you will let one of the formatting
-commands do this job for you. @xref{Create an Info File}.)@refill
-
-The split-off files are called the indirect subfiles.@refill
-
-Info files are split to save memory. With smaller files, Emacs does not
-have make such a large buffer to hold the information.@refill
-
-If an Info file has more than 30 nodes, you should also make a tag
-table for it. @xref{Using Info-validate}, for information
-about creating a tag table. (Again, tag tables are usually created
-automatically by the formatting command; you only need to create a tag

-@code{Info-validate}.)@refill
-
-@c Info-split is autoloaded in `loaddefs.el' in Emacs 18.51

-Before running @code{Info-split}, you need to load the @code{info} library

-(Note that the @samp{I} in @samp{Info} is upper case.)@refill
-
-When you use the @code{Info-split} command, the buffer is modified into a

-saved in place of the original visited file. The indirect subfiles are
-written in the same directory the original file is in, with names generated
-by appending @samp{-} and a number to the original file name.@refill

-@findex refill
-
-The @code{@@refill} command refills and, optionally, indents the first
-line of a paragraph.@footnote{Perhaps the command should have been
-called the @code{@@refillandindent} command, but @code{@@refill} is
-shorter and the name was chosen before indenting was possible.} The
-@code{@@refill} command is no longer important, but we describe it here
-because you once needed it. You will see it in many old Texinfo
-files.@refill
-
-Without refilling, paragraphs containing long @@-constructs may look
-bad after formatting because the formatter removes @@-commands and
-shortens some lines more than others. In the past, neither the
-@code{texinfo-format-region} command nor the
-@code{texinfo-format-buffer} command refilled paragraphs
-automatically. The @code{@@refill} command had to be written at the
-end of every paragraph to cause these formatters to fill them. (Both
-@TeX{} and @code{makeinfo} have always refilled paragraphs
-automatically.) Now, all the Info formatters automatically fill and
-indent those paragraphs that need to be filled and indented.@refill
-
-The @code{@@refill} command causes @code{texinfo-format-region} and
-@code{texinfo-format-buffer} to refill a paragraph in the Info file
-@emph{after} all the other processing has been done. For this reason,
-you can not use @code{@@refill} with a paragraph containing either
-@code{@@*} or @code{@@w@{ @dots{} @}} since the refilling action will
-override those two commands.@refill
-
-The @code{texinfo-format-region} and @code{texinfo-format-buffer}
-commands now automatically append @code{@@refill} to the end of each
-paragraph that should be filled. They do not append @code{@@refill} to
-the ends of paragraphs that contain @code{@@*} or @w{@code{@@w@{ @dots{}@}}}
-and therefore do not refill or indent them.@refill
-
-@node Command Syntax, Obtaining TeX, Refilling Paragraphs, Top
-@comment node-name, next, previous, up
-@appendix @@-Command Syntax
-@cindex @@-command syntax
-
-The character @samp{@@} is used to start special Texinfo commands.
-(It has the same meaning that @samp{\} has in plain @TeX{}.) Texinfo
-has four types of @@-command:@refill
-
-@table @asis
-@item 1. Non-alphabetic commands.
-These commands consist of an @@ followed by a punctuation mark or other
-character that is not part of the alphabet. Non-alphabetic commands
-are almost always part of the text within a paragraph, and never take
-any argument. The two characters (@@ and the other one) are complete
-in themselves; none is followed by braces. The non-alphabetic
-commands are: @code{@@.}, @code{@@:}, @code{@@*}, @code{@@@@},
-@code{@@@{}, and @code{@@@}}.@refill
-
-@item 2. Alphabetic commands that do not require arguments.
-These commands start with @@ followed by a word followed by left- and
-right-hand braces. These commands insert special symbols in the
-document; they do not require arguments. For example,
-@code{@@dots@{@}} @result{} @samp{@dots{}}, @code{@@equiv@{@}}
-@result{} @samp{@equiv{}}, @code{@@TeX@{@}} @result{} `@TeX{}',
-and @code{@@bullet@{@}} @result{} @samp{@bullet{}}.@refill
-
-@item 3. Alphabetic commands that require arguments within braces.
-These commands start with @@ followed by a letter or a word, followed by an
-argument within braces. For example, the command @code{@@dfn} indicates
-the introductory or defining use of a term; it is used as follows: @samp{In
-Texinfo, @@@@-commands are @@dfn@{mark-up@} commands.}@refill
-
-@item 4. Alphabetic commands that occupy an entire line.
-These commands occupy an entire line. The line starts with @@,
-followed by the name of the command (a word); for example, @code{@@center}
-or @code{@@cindex}. If no argument is needed, the word is followed by
-the end of the line. If there is an argument, it is separated from
-the command name by a space. Braces are not used.@refill
-@end table
-
-@cindex Braces and argument syntax
-Thus, the alphabetic commands fall into classes that have
-different argument syntaxes. You cannot tell to which class a command
-belongs by the appearance of its name, but you can tell by the
-command's meaning: if the command stands for a glyph, it is in
-class 2 and does not require an argument; if it makes sense to use the
-command together with other text as part of a paragraph, the command
-is in class 3 and must be followed by an argument in braces;
-otherwise, it is in class 4 and uses the rest of the line as its
-argument.@refill
-
-The purpose of having a different syntax for commands of classes 3 and
-4 is to make Texinfo files easier to read, and also to help the GNU
-Emacs paragraph and filling commands work properly. There is only one
-exception to this rule: the command @code{@@refill}, which is always
-used at the end of a paragraph immediately following the final period
-or other punctuation character. @code{@@refill} takes no argument and
-does @emph{not} require braces. @code{@@refill} never confuses the
-Emacs paragraph commands because it cannot appear at the beginning of
-a line.@refill
