What are its advantages over `eldoc-mode'?

   eldoc-mode is an interactive autoloaded Lisp function in `eldoc'.
   (eldoc-mode &optional arg)

   Toggle ElDoc mode on or off.
   In ElDoc mode, the echo area displays information about a
   function or variable in the text where point is.  If point is
   on a documented variable, it displays the first line of that
   variable's doc string.  Otherwise it displays the argument list
   of the function called in the expression point is on.

   With prefix arg, turn ElDoc mode on if and only if arg is positive.
