# This is set up for Debian.  Solaris places fonts in
# "/usr/share/fonts/TrueType".  Other unices use other directories.
# The original font format was BDF, but Debian doesn't use that and
# xfs should only need TrueType, so the BDF font isn't installed.
#
# The TrueType font is about 16 Megabytes.  To avoid duplication,
# the fonts are installed as symbolic links back to the original package.
# Alternatively, the fonts can be copied to the destination directory
# with "install -m0644" or moved there (but "mv" is a destructive
# one-time operation).
#
# After installing the new fonts, register them with X Window System using:
#
#      xset fp rehash
