Yeah, assuming *it evaluates to an integer (I'm not too familiar with 
the STL) this is how I imagine you would print a subset of pages.

Uh, maybe... I don't know, actually, but in that case we PSFile 
constructor will just have to take the number of pages as an argument. 
In that case, before you create the PSFile, you'll have to count your 
pages first.
