+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.
