+# 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.
