[gs-devel] Splitting a multipage pdf

[Jeremy Rottman]

I know that I can split a multi-page pdf if I use something like below. 
But the issue that I am having is that I will never know exactly how 
many pages are in the pdf files that I am working with. Is there a way 
to determine the number of pages or even better is there a way to split 
the pdf with out passing the firstpage or lastpage?

Any help with this is greatly appreciated.
