  39 This is the file .../info/dir, which contains the topmost node of the
  40 Info hierarchy.  The first time you invoke Info you start off
  41 looking at that node, which is (dir)Top.
  42 \x1f
  43 File: dir       Node: Top       This is the top of the INFO tree
  44   This (the Directory node) gives a menu of major topics.
  45   Typing "d" returns here, "q" exits, "?" lists all INFO commands, "h"
  46   gives a primer for first-timers, "mTexinfo<Return>" visits Texinfo topic,
  47   etc.
  48   --- PLEASE ADD DOCUMENTATION TO THIS TREE. (See INFO topic first.) ---

  50 * Menu: The list of major topics begins on the next line.

  60 ### additional files remain (ones that don't have a template entry),
  61 ### then generate entries for those in the same way, putting the info for
  62 ### those at the very end....
