Fourier-GUTenberg package, Latin letters and digits are borrowed from
Michael Shape’s Erewhon font.

* Erewhon-Math.pdf     Documentation in PDF format
* Erewhon-Math.ltx     Source of Erewhon-Math.pdf
* unimath-erewhon.pdf  Modified version of unimath-symbols.pdf
                       showing available Erewhon-Math symbols compared to

## Installation

This package is meant to be installed automatically by TeXLive, MikTeX, etc.
Otherwise, Erewhon-Math can be installed under TEXMFHOME or TEXMFLOCAL, f.i.
Erewhon-Math.otf in directory  texmf-local/fonts/opentype/public/erewhon-math/
and
fourier-otf.sty  in directory  texmf-local/tex/latex/erewhon-math/
Documentation files and their sources can go to directory
texmf-local/doc/fonts/public/erewhon-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 Erewhon Math font
(fontconfig under Linux).
