I'm trying to build tyscheme, which is a TeX (not LaTeX) document. The README file directs me to run a sequence of commands, the first one is
luatex index, which fails as it can't find file
\include. A search directs me to the TeX-Gyre fonts, which I do have installed (there is a
tgtermes.sty package for LaTeX here).
Local environment is TeXlive on Fedora 33.
