# Concmath-otf package

## Description

`Concrete-Math.otf’ is an Opentype version of the Concrete Math font`

created by Ulrik Vieth in METAFONT. `concmath-otf.sty’ is a replacement`

for the original `concmath.sty’ package.`

## Contents

- Concrete-Math.otf OpenType Math font
- concmath-otf.sty LaTeX style file: replaces concmath.sty for LuaTeX/XeTeX
- concmath-otf.pdf Documentation in PDF format
- concmath-otf.ltx LaTeX source of concmath-otf.pdf
- unimath-concrete.pdf Modified version of unimath-symbols.pdf showing available Concrete-Math symbols compared to

LatinModern, STIXTwo, TeXGyrePagella and DejaVu.

## Installation

This package is meant to be installed automatically by TeXLive, MikTeX, etc. Otherwise, the package can be installed under TEXMFHOME or TEXMFLOCAL, f.i. Concrete-Math.otf in directory texmf-local/fonts/opentype/public/concmath-otf/ and concmath-otf.sty in directory texmf-local/tex/latex/concmath-otf/. Documentation files and their sources can go to directory texmf-local/doc/fonts/public/concmath-otf/

Don't forget to rebuild the file database (mktexlsr or so) if you install under TEXMFLOCAL.

Finally, make the system font database aware of the Concrete-Math font (fontconfig under Linux).
