2# Some of HarfBuzz's headers are created at build time using the Ragel
3# State Machine Compiler.  To reduce complex dependencies, I pre-built
4# these files:
5#     hb-buffer-deserialize-json.hh
6#     hb-buffer-deserialize-text.hh
7#     hb-ot-shape-complex-indic-machine.hh
8#     hb-ot-shape-complex-myanmar-machine.hh
9#     hb-ot-shape-complex-use-machine.hh
10# from these sources:
11#     ../externals/harfbuzz/src/hb-buffer-deserialize-json.rl
12#     ../externals/harfbuzz/src/hb-buffer-deserialize-text.rl
13#     ../externals/harfbuzz/src/hb-ot-shape-complex-indic-machine.rl
14#     ../externals/harfbuzz/src/hb-ot-shape-complex-myanmar-machine.rl
15#     ../externals/harfbuzz/src/hb-ot-shape-complex-use-machine.rl
16#
17# The files in this directory are created by installing the
18# prerequiste packages, checking out a new version of HarfBuzz, doing
19# `./autogen.sh && ./configure && make`, then copying the
20# autogenerated .h and .hh files to this directory.
