A master menu is a detailed main menu listing all the nodes in a file.
A master menu is enclosed in
commands and does not appear in the printed document.
Generally, a master menu is divided into parts.
Each section in the menu can be introduced by a descriptive line. So long as the line does not begin with an asterisk, it will not be treated as a menu entry. (See section Writing a Menu, for more information.)
For example, the master menu for this manual looks like the following (but has many more entries):
@menu * Copying:: Texinfo is freely redistributable. * Overview:: What is Texinfo? * Texinfo Mode:: Special features in GNU Emacs. ... ... * Command and Variable Index:: An entry for each @-command. * Concept Index:: An entry for each concept. -- The Detailed Node Listing --- Overview of Texinfo * Info Files:: What is an Info file? * Printed Manuals:: Characteristics of a printed manual. ... ... Using Texinfo Mode * Info on a Region:: Formatting part of a file for Info. ... ... @end menu
