a great program. Using it for quite a while on OSX Panther and Tiger in production environment. Works extremely well and handles correctly spot colors and fonts. It has an option not only to burst the output but also to rename it correctly.

pdftk myfile.pdf burst output myNEWname_"percent sign"03d.pdf

this would burst the file and output in a new name with keeping always 3 spaces for number - like 003, 033, 133 so they are in correct order on the sort.

Pdftk's ability to join two or more PDF files is on par with such specialized applications as pdfmeld and joinPDF (discussed in this article). The command syntax is simple:

pdftk file1.pdf file2.pdf cat output newFile.pdf

cat is short for concatenate -- that is, link together, for those of us who speak plain English -- and output tells pdftk to write the combined PDFs to a new file.
