Extract only last page from PDF - batch

Hi,

I need to extract the last page from about 100 documents in a batch process.  I need the last page only, and the number of pages in each document varies (i.e. one might be 30, one might be 200).

Is there any way to do this without having to go into each individual document and extracting the last page?

On the discussion forums I found a javascript to enter in Action Wizard that enabled you to delete the last page, but not extract it or delete the pages in front of it.

Thanks!
