  31 ** Usage
  32 *** Generate a combined PDF
  33 [[https://inkscape.org/][Inkscape]] is used to convert SVGs to individual PDFs but a script is
  34 available at ~./EXEC/combine_pdfs.sh~ to merge multiple single-page
  35 PDFs into a single PDF file; the script uses the [[https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/][~pdftk~ utility]]
  36 available on typical [[https://www.debian.org/][Debian]]-based [[https://en.wikipedia.org/wiki/Gnu-Linux][GNU/Linux]] machines of 2023. On a
  37 typical Debian 12 system, the following command may be used to merge
  38 ~input1.pdf~ and ~input2.pdf~ files into ~output.pdf~.
  39
  40 : $ /bin/bash combine_pdfs.sh output.pdf ~input1.pdf~ ~input2.pdf~
