Some stuff I've collected to typeset things the way I like.

I put these files inside of ~/Library/texmf/, and reference them in general (Xe)LaTeX documents.

That is, they could be cloned like this:

mkdir ~/Library/texmf
git clone https://github.com/postylem/tex_utils.git ~/Library/texmf/custom

and then used in a LaTeX file. See example tex_utils_demo.tex (I compile with latexmk -xelatex).
