# Some of HarfBuzz's headers are created at build time using the Ragel
# State Machine Compiler. To reduce complex dependencies, I pre-built
# these files:
# hb-buffer-deserialize-json.hh
# hb-buffer-deserialize-text.hh
# hb-ot-shape-complex-indic-machine.hh
# hb-ot-shape-complex-myanmar-machine.hh
# hb-ot-shape-complex-use-machine.hh
# from these sources:
# ../externals/harfbuzz/src/hb-buffer-deserialize-json.rl
# ../externals/harfbuzz/src/hb-buffer-deserialize-text.rl
# ../externals/harfbuzz/src/hb-ot-shape-complex-indic-machine.rl
# ../externals/harfbuzz/src/hb-ot-shape-complex-myanmar-machine.rl
# ../externals/harfbuzz/src/hb-ot-shape-complex-use-machine.rl
#
# The files in this directory are created by installing the
# prerequiste packages, checking out a new version of HarfBuzz, doing
# `./autogen.sh && ./configure && make`, then copying the
# autogenerated .h and .hh files to this directory.
