This book was structured using Pandoc created by John MacFarlane,
and typeset using Xelatex created by Jonathan Kew.

The body text is set 10/12pt on a \mytodo{actual measure}{33pc} measure
with Lora designed by Ольга Карпушина (Olga Karpushina).
Other fonts include Quattrocento Sans and Inconsolata.

All work was done on a Debian system,
solely using tools and data in the digital commons.
