In this chapter, we're going to solve some problems when working with existing PDFs that need to be split into different files, merged or stamped. Usually, we are going to use a combination of PdfReader to read the document and PdfStamper, PdfCopy or PdfSmartCopy to create a new PDF. Note that we'll skip filling out interactive forms for now. We'll deal with AcroForm and XFA technology in the next chapter
