[pdftex] define pdf variable and then reference it?

Well, if it's only adding a heading or watermark to some existing PDF,
my feeling is that, while  generating a new PDF from source might be
slow, using pdfpages to just include the existing PDF and add things
over the pages is very fast, simple to achieve, and reliable.
