r-cran-qpdf 1.1+dfsg-1build2 (riscv64 binary) in ubuntu groovy

 Content-preserving transformations of PDF files such as split, combine,
 and compress. This package interfaces directly to the 'qpdf' C++ API
 and does not require any command line utilities. Note that 'qpdf' does
 not read actual content from PDF files: to extract text and data you
 need the 'pdftools' package.
