# IMPORTANT NOTICE about XftConfig:
#
# The XftConfig config file has been deprecated and obsoleted by
# /etc/fonts.conf, which is the new font configuration file for Xft2, and
# is provided by "fontconfig".  A backward compatible Xft1 library is also
# provided which has been converted to use fontconfig also and provide users
# with a single way of configuring client side fonts, while retaining binary
# compatibility. For information on configuring fonts using fontconfig,
# please consult the fontconfig documentation.
