# The build scripts for Type 1 fonts need some afm files already
# available. If new TTF files are released, it is best to keep the
# old Type 1 fonts, copy the new TTF files and run the scripts.
#
# Currently, the scripts first make additional kerning pairs from
# the existing afm files and then convert the fonts to Type 1 format
# using these additional kerning pairs. That means that you may need to
# run "make" twice to get stable result if you change some metrics in the
# script ff-gentium.pe. For example if you change the kern value for the
# pair DV, then the first run will change the value just for this pair and
# the second run will change the values also for all the derived pairs
# (accented letters, small caps).
