Note that one way to reduce size is using Acrobat and to require
compatibility only with higher versions. However then it may become
incompatible with the earlier versions of Acrobat; pretex compression
can make it incompatible with TeX (the latest pdftex 1.40 accepts pdf
<= 1.5 which corresponds to  Acrobat 6)
