The Parts of a Menu
===================
A menu entry has three parts, only the second of which is required:
1. The menu entry name (optional).
2. The name of the node (required).
3. A description of the item (optional).
The template for a menu entry looks like this:
* MENU-ENTRY-NAME: NODE-NAME. DESCRIPTION
Follow the menu entry name with a single colon and follow the node
name with tab, comma, period, or newline.
In Info, a user selects a node with the `m' (`Info-menu') command.
The menu entry name is what the user types after the `m' command.
The third part of a menu entry is a descriptive phrase or sentence.
Menu entry names and node names are often short; the description
explains to the reader what the node is about. A useful description
complements the node name rather than repeats it. The description,
which is optional, can spread over two or more lines; if it does, some
authors prefer to indent the second line while others prefer to align it
with the first (and all others). It's up to you.
