  and exported PDF files. *This is probably what you want*.
- ~DWG~: Drawing source files. A directory that may include [[https://inkscape.org/][Inkscape]]
  SVG files.
- ~EXEC~: Executable files. A directory that may include scripts
  useful for manipulating files.
- ~IMG~: Reference image files. A directory that may include various
  image files used in creation of project source files.
*** Files

** Usage
*** Generate a combined PDF
A script is available at ~./EXEC/combine_pdfs.sh~ to merge multiple
single-page PDFs into a single PDF file; the script uses the [[https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/][pdftk
utility]] available on typical [[https://www.debian.org/][Debian]]-based [[https://en.wikipedia.org/wiki/Gnu-Linux][GNU/Linux]] machines
of 2023. On a typical Debian 12 system, the following command may be
used to merge ~input1.pdf~ and ~input2.pdf~ files into ~output.pdf~.

: $ /bin/bash combine_pdfs.sh output.pdf input1.pdf input2.pdf
