Scott,

thanks for the reply, as always; 
   ...
   Presentation type options do not inherit.  This was an explicit design
   decision, but since it was made about three years ago, I can no longer
   remember what the rationale was.

WHAT!?  Where's your paper-trail?  You may be called in front of
Congress someday... :)

     (define-presentation-type pathname ()
       :inherit-from t                     ;enforce CL definition
what does this mean?

       :history t
       :options ((default-type nil)
		 (default-version :newest)
		 (merge-default t)))

can these options then be used in &key for 'present' methods?

Sorry to ask something that might be in the book
(i.e., READ...THE...BOOK!), but I couldn't find it.

jeff
