PDFToolkit allows to reorganize PDF files.
It can split and merge documents.
Additionally it can combine two or three PDF files
by stamping over or add header/footer/page numbering
to existed documents keeping the contents intact.

It uses pyPDF python module by Mathieu Fenniak.
If you are online, it can download and install that
module automatically.
If not, you can get it here: http://pybrary.net/pyPdf/

Have fun!
