--debug print debug information to standard error path
-d, --delete delete invalid menu items (ignore missing menu items)
-f do not load functions (file update-info.f)
--help print this help message and exit
-i, --interactive interactive mode prompts before inserting or removing
menu items
--version print current version and exit
Backup of the info node has a '.old' suffix added. This is a shell script.
Files: update-info.f -- contains functions (optional).
Environment Variables: COLUMNS, EDITOR, LINES, TMPDIR

This is the file .../info/dir, which contains the topmost node of the
Info hierarchy. The first time you invoke Info you start off
looking at that node, which is (dir)Top.

File: dir Node: Top This is the top of the INFO tree
This (the Directory node) gives a menu of major topics.
Typing "d" returns here, "q" exits, "?" lists all INFO commands, "h"
gives a primer for first-timers, "mTexinfo<Return>" visits Texinfo topic,
etc.
Or click mouse button 2 on a menu item or cross reference to select it.
--- PLEASE ADD DOCUMENTATION TO THIS TREE. (See INFO topic first.) ---
* Menu: The list of major topics begins on the next line.
