Luciole package

Description

This package provides four Unicode Math text fonts Luciole-*.ttf and a companion maths font Luciole-Math.otf.
They have been developed explicitly for visually impaired people and are the result of a collaboration between the Regional Technical Center for Visual Impairment, the type-design studio typographies.fr and the mathematician Daniel Flipo. The Luciole project received a grant from the Swiss Ceres Foundation and the PEP69 association, and support from the DIPHE laboratory at the Université Lumière Lyon 2 and the association GUTenberg.

Installation

This package `Luciole’ is meant to be installed automatically by TeXLive, MikTeX, etc. Otherwise, can be installed under TEXMFHOME or TEXMFLOCAL, f.i. text and math fonts in directory texmf-local/fonts/truetype/public/luciole/, and luciole-math.sty, Luciole.fontspec in directory texmf-local/tex/latex/luciole/.
Documentation files and their sources can go to directory texmf-local/doc/fonts/public/luciole/

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 Luciole fonts (fontconfig under Linux).
