# Subsetting DejaVu fonts to create a display-math-only font
# The DejaVu fonts include math display variants outside of the Unicode range,
# and it is currently hard to access them from matplotlib. The subset.py script
# in `tools` has been modified to move the math display variants found in DejaVu
# fonts into a new TTF font with these variants in the Unicode range.
# This bash script calls the subset.py scripts with the appropriate options to
# generate the new font files `DejaVuSansDisplay.ttf` and
# `DejaVuSerifDisplay.ttf`:
mpldir=$(dirname $0)/../
# test that fontforge is installed
python -c 'import fontforge' 2> /dev/null
