Rails wrapper around the PrinceXML PDF generator: renders PDF templates via a `:pdf` render option, registers PDF as a respond_to MIME type, provides a `make_and_send_pdf` helper, and supports custom layouts/stylesheets/locals, asset path rewriting, inline/attachment disposition, JS and PDF-form flags, and configurable timeouts.
Requires a PrinceXML installation (proprietary, license required for output without a watermark).
