Possible to generate pdf file for https://github.com/walkccc/CLRS?

The following should generate a pdf of everything. Some katex is not parsed for some reason though, haven't checked why yet. Depends on pandoc, pdfunite, and chromium.
mycat() {
    sed 's#\.\./img#docs/img#g' "$1"
}

rm -rf mkpdf
mkdir -p mkpdf

# mostly the default pandoc css, with few modifications
cat > mkpdf/mkpdf.css <<EOF
