Installation

This package is meant to be installed automatically by Live, Mik, 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).
