What they mean is a function in a traditional Lisp dialect (e.g. Common 
Lisp or Maclisp) that doesn't exist in Emacs Lisp.  If you want to use 
such a function in your own package, you need to write it yourself -- 
and the recommendation is that you personalize it with a prefix, so you 
don't conflict with another package that has a similar need.
