# The source tarball contains code from 3 git repositories:
# https://github.com/dse/bitmapfont2ttf
# https://github.com/dse/exact-autotrace
# https://github.com/wernsey/bitmap.git
# ...plus some minor fixes by me to get exact-autotrace to compile.

# 20200621 bkw: the fonts produced by some tools (notably psf2bdf)
# are missing the PIXEL_SIZE property. Patched code derives it from the
# ascent and descent properties, if necessary. This isn't always correct,
# but for the 670 fonts in /usr/share/fonts/misc (converted to BDF),
# it's correct for 654 (98%) of them.
