A new, experimental, faster system to load OpenType math fonts in LuaLaTeX documents.

To start using this package, load a lua-unicode-math supported math font package like lum-lmodern:

\documentclass{article}
\usepackage{lum-lmodern}
\begin{document}
\[
  x_{1/2}=-\frac p2\pm\sqrt{\frac{p^2}4-q}
\]
\end{document}

The package is available under the LaTeX Project Public License, version 1.3c or later.
