Today I needed to split up a PDF and went looking for a tool that would do that for me. I came across the project named PDF Toolkit (http://www.accesspdf.com/pdftk/).
Using this tool I executed the following command and, voila, I had one PDF document for each page in my input document:
pdftk.exe input_file.pdf burst
Check the included .txt file for the full set of command-line parameters.
