What's a spline?

   [XEROX  PARC] This phrase expands to: "You have just used a term that
   I've  heard  for  a  year  and  a half, and I feel I should know, but
   don't.  My curiosity has finally overcome my guilt." The PARC lexicon
   adds  "Moral:  don't  hesitate  to  ask  questions, even if they seem
   obvious."
