 Tree structured help facility

 The help library is basically tree structured.  This program allows
 the user to walk through the tree using simple commands.

 Commands:
    Command    Function
    .(node)    Move down to sub-key (node)
    ^          Move up to this node's parent
    >(node)    Move across to this node's brother, (node)
    /(qual)    Move to a qualifier for this command
    (node)     Move directly to the top-level help for (node)
2 Down
 To move down in the tree, use the . command.  For example, if you just
 looked at the help information for the "SET" command, and want to know
 the specifics on "SET TERMINAL", you would type, ".TERMINAL"
2 Up
 To move up in the tree, use the ^ command.

 For example, after looking at the information on SET TERMINAL, "^"
 would return you to the help on "SET".
2 Across
 The > command may be used to move across a level of the tree.

 For example, after looking at the information on "SET TERMINAL",
 the command ">PROCESS" would move you to the description of the
 "SET PROCESS" command.
2 Qualifiers
 If you type in the name of a qualifier, the action is dependant on
 what you are looking at.

 If you are looking at a qualifier, you are moved across the tree
 to look at a different qualifier for the same main command.

 Otherwise, you are moved down one level to the description of
 the desired qualifier.

 Example:
   If you are looking at the information for SET TERMINAL, typing
   "/WRAP" will give you the help for SET TERMINAL/WRAP.  Then,
   typing "/SCOPE" will move you laterally to the help for
   SET TERMINAL/SCOPE.
