PDFTK Builder

PDFTK Builder is a nifty little PDF utility if you don't have or don't want a full blown Adobe Acrobat just for collating, splitting, rotating, stamping and password settings in PDF files. It is a frontend to pdftk (but does not need to have pdftk itself beeing installed).

PDFTK Builder seems to use Inno Setup.
