I have a document where, in parts, I need two page numbers per page. I
know, this sounds nutty. But, the document contains several sections that
are, themselves, stand-alone documents. So, I want to use automatic page
numbering throughout the long document, with each page being numbered one
more than the previous one. BUT, for some sections of the document I want
to have a second page number, numbered from 1 to whatever for just that
section.

How can I do this?
