As you are only "vetting", Doug, and not being called on to "massage", 
the following will not be strictly relevant but may nonetheless be of 
interest.  For a 6-page, tri-fold, A4 menu, my printer recommend that 
pp.~1 & 4 be 1 mm narrower than the other pages, to allow the fold to 
tuck in neatly.  Whilst I /could/ have elected to tackle this in the 
master document I preferred not to, so what I did instead was to write a 
second TeX program to read the output of the first as data, massage the 
resulting information, and then ship out the massaged content.  See below.
