Euler-Math package
====================
## Description
'Euler-Math.otf' (formerly named 'Neo-Euler.otf') is an OpenType version of
Hermann Zapf’s Euler maths font. It is the continuation of the Euler project
initiated by Khaled Hosny in 2009 and abandoned in 2016.
A style file 'euler-math.sty' is provided as a replacement of the
'eulervm.sty' package for LuaLaTeX and XeLaTeX users.
## Contents
* Euler-Math.otf OpenType maths font
* euler-math.sty LaTeX style file: replaces eulervm.sty for LuaTeX/XeTeX
* neo-euler.sty For compatibility with the former name
* Euler-Math.pdf Documentation in PDF format
* Euler-Math.ltx LaTeX source of Euler-Math.pdf
* unimath-euler.pdf Modified version of unimath-symbols.pdf
showing available Euler-Math symbols compared to
LatinModern, STIXTwo, Erewhon, TeXGyrePagella and Asana.
* unimath-euler.ltx LaTeX source of unimath-concrete.pdf
* README.md (this file)
## 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.
Euler-Math.otf in directory texmf-local/fonts/opentype/public/euler-math/
and euler-math.sty in directory texmf-local/tex/latex/euler-math/.
Documentation files and their sources can go to directory
texmf-local/doc/fonts/public/euler-math/
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 Euler-Math font
(fontconfig under Linux).

## Changes
* First public version: 0.20
* v0.21:
- Delimiters, integrals, sum, prod etc. are now vertically
centred by design on the maths axis (required by luametatex).
* v0.22:
- Sizes of vertical variants of \lAngle, \rAngle, \langle and
\rangle corrected.
- Added stretchable integral for U+222B (usable with luametatex).
* v0.30:
- *Name of the package changed from Neo-Euler to Euler-Math*;
the former 'neo-euler.sty' style file has been kept for compatibility,
it now loads 'euler-math.sty' and warns about the change.
* v0.31:
- Package now compatible with mathtools’ stretchable arrows.
- \diagup and \diagdown moved from private area to U+27CB, U+27CD.
* v0.40:
- Metrics of all "over" arrows and harpoons corrected.
- Metrics of all "under" arrows and harpoons corrected.
- Most horizontal arrows and harpoons are now stretchable.
* v0.41:
- radicals corrected.
- euler-math.sty: options handled by `l3keys` instead of `xkeyval`
(requires a LaTeX kernel not older than 2022-06-01).
* v0.50:
- Italic and BoldItalic alphabets filled with their upright
counterparts as suggested by Ulrik Vieth.
- Sans-serif alphabets (Latin and Greek) added, they are derived from
IBMPlexSans text fonts.
- Typewriter alphabet (Latin) added, derived from UMTypewriter-Regular.
