While writing and picking a name for this tool, I discovered both QPDF and PDFtk ("tool kit") Server, both of which offer many more features. This project is definitely not a tool kit, but maybe it's a single tool: a hammer. It's not always the perfect tool for the job, but if you only need something simple to then a hammer might do.
