+Some languages / markups I use aren't supported by minted, so I map
+them here so they don't fail.

+****** TeX Engine
+
+Prepare the LaTeX export process, and default the compiler to xelatex,
+as it has better unicode support than pdflatex.
+
+#+BEGIN_NOTES
+The =%latex= expansion variable is used so that org documents can
+override the latex compiler using the file-level =LATEX_COMPILER=
+directive.
