  "Update one node (or many) in a Texinfo file with sequential pointers.

This function causes the `Next' or `Previous' pointer to point to the
immediately preceding or following node, even if it is at a higher or
lower hierarchical level in the document.  Continually pressing `n' or
`p' takes you straight through the file.

Without any prefix argument, update the node in which point is located.
Non-nil argument (prefix, if interactive) means update the nodes in the
marked region.

This command makes it awkward to navigate among sections and
subsections; it should be used only for those documents that are meant
to be read like a novel rather than a reference, and for which the
Info `g*' command is inadequate."

(autoload 'texinfo-make-menu
  "texnfo-upd"
  "Without any prefix argument, make or update a menu.
Make the menu for the section enclosing the node found following point.

Non-nil argument (prefix, if interactive) means make or update menus
for nodes within or part of the marked region.

Whenever a menu exists, and is being updated, the descriptions that
are associated with node names in the pre-existing menu are
incorporated into the new menu.  Otherwise, the nodes' section titles
are inserted as descriptions."
  t nil)

(autoload 'texinfo-all-menus-update
  "texnfo-upd"
  "Update every regular menu in a Texinfo file.
Remove pre-existing master menu, if there is one.

If called with a non-nil argument, this function first updates all the
nodes in the buffer before updating the menus."
  t nil)

(autoload 'texinfo-master-menu
  "texnfo-upd"
  "Make a master menu for a whole Texinfo file.
Non-nil argument (prefix, if interactive) means first update all
existing nodes and menus.  Remove pre-existing master menu, if there is one.

This function creates a master menu that follows the top node.  The
master menu includes every entry from all the other menus.  It
replaces any existing ordinary menu that follows the top node.

If called with a non-nil argument, this function first updates all the
menus in the buffer (incorporating descriptions from pre-existing
menus) before it constructs the master menu.

The function removes the detailed part of an already existing master
menu.  This action depends on the pre-existing master menu using the
standard `texinfo-master-menu-header'.

The master menu has the following format, which is adapted from the
recommendation in the Texinfo Manual:

   * The first part contains the major nodes in the Texinfo file: the
     nodes for the chapters, chapter-like sections, and the major
     appendices.  This includes the indices, so long as they are in
     chapter-like sections, such as unnumbered sections.

   * The second and subsequent parts contain a listing of the other,
     lower level menus, in order.  This way, an inquirer can go
     directly to a particular node if he or she is searching for
     specific information.

Each of the menus in the detailed node listing is introduced by the
title of the section containing the menu."
  t nil)

(autoload 'texinfo-indent-menu-description
  "texnfo-upd"
  "Indent every description in menu following point to COLUMN.
Non-nil argument (prefix, if interactive) means indent every
description in every menu in the region.  Does not indent second and
subsequent lines of a multi-line description."
  t nil)

(autoload 'texinfo-insert-node-lines
  "texnfo-upd"
  "Insert missing `@node' lines in region of Texinfo file.
Non-nil argument (prefix, if interactive) means also to insert the
section titles as node names; and also to insert the section titles as
node names in pre-existing @node lines that lack names."
  t nil)

(autoload 'texinfo-start-menu-description
  "texnfo-upd"
  "In this menu entry, insert the node's section title as a description.
Position point at beginning of description ready for editing.
Do not insert a title if the line contains an existing description.

You will need to edit the inserted text since a useful description
complements the node name rather than repeats it as a title does."
  t nil)

(autoload 'texinfo-multiple-files-update
  "texnfo-upd"
  "Update first node pointers in each file included in OUTER-FILE;
create or update main menu in the outer file that refers to such nodes.
This does not create or update menus or pointers within the included files.

With optional MAKE-MASTER-MENU argument (prefix arg, if interactive),
insert a master menu in OUTER-FILE.  This does not create or update
menus or pointers within the included files.

With optional UPDATE-EVERYTHING argument (numeric prefix arg, if
interactive), update all the menus and all the `Next', `Previous', and
`Up' pointers of all the files included in OUTER-FILE before inserting
a master menu in OUTER-FILE.

The command also updates the `Top' level node pointers of OUTER-FILE.

Notes:

  * this command does NOT save any files--you must save the
    outer file and any modified, included files.

  * except for the `Top' node, this command does NOT handle any
    pre-existing nodes in the outer file; hence, indices must be
    enclosed in an included file.

Requirements:

  * each of the included files must contain exactly one highest
    hierarchical level node,
  * this highest node must be the first node in the included file,
  * each highest hierarchical level node must be of the same type.

Thus, normally, each included file contains one, and only one,
chapter."
