Thanks. Attached is my next iteration. This is almost what I want,
however, I'm sure it's wrong in the details. Reason: It accepts
#(set-default-paper-size '(cons 100 50))
(at the top level) but dislikes
#(set-default-paper-size '(100 . 50))
How can I fix this? Again, any pointers are much appreciated.
