"We have also benefited from the various open-source packages on which this textbook depends (see appendix G). The typesetting of the code was done with the help of pythontex, which is maintained by Geoffrey Poore. The typeface used for the algorithms is JuliaMono (github.com/cormullion/juliamono). The plotting was handled by pgfplots, which is maintained by Christian Feuersänger" ?
