[docbook-apps] Page shrinking or scaling

[DeanNelson]

Hi y'all,
 
Is there a way to shrink the page size in Docbook without having to  
reformat the doc going to PDF (FOP).
 
My users would like to have a "half size" manual to travel with instead of  
a regular US Letter size page. I guess I could to this at the printers, but 
it  would be nice if I could do it at the office.
 
I tried adjusting the page.height and .width but that just messed things up 
 because the fonts were still the same size as were the images.
 
Any ideas?
 
Regards,
Dean Nelson
