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.
--- PLEASE ADD DOCUMENTATION TO THIS TREE. (See INFO topic first.) ---
* Menu: The list of major topics begins on the next line.

### go through the list of files in the template. If an info file
### exists, grab the ENTRY information from it. If there is no entry
### info, then create a minimal dir entry, otherwise use the given info.

### Then remove that file from the list of existing files. If any
### additional files remain (ones that don't have a template entry),
### then generate entries for those in the same way, putting the info for
### those at the very end....
