+# This tool is used to prepare lookup tables of Unicode character properties
+# needed by gfx code to support text shaping operations. The properties are
+# read from the Unicode Character Database and compiled into multi-level arrays
+# for efficient lookup.
+#
+# To regenerate the tables in nsUnicodePropertyData.cpp:
+#
+# (1) Download the current Unicode data files from
+#
+# http://www.unicode.org/Public/UNIDATA/
+#
+# NB: not all the files are actually needed; currently, we require
+# - UnicodeData.txt
+# - Scripts.txt
+# - BidiMirroring.txt
+# - BidiBrackets.txt
+# - HangulSyllableType.txt
+# - LineBreak.txt
+# - EastAsianWidth.txt
+# - ReadMe.txt (to record version/date of the UCD)
+# - Unihan_Variants.txt (from Unihan.zip)
+# though this may change if we find a need for additional properties.
+#
+# The Unicode data files listed above should be together in one directory.
+#
+# We also require the file
+# http://www.unicode.org/Public/security/latest/xidmodifications.txt
+# This file should be in a sub-directory "security" immediately below the
+# directory containing the other Unicode data files.
+#
+# We also require the latest data file for UTR50, currently revision-13:
+# http://www.unicode.org/Public/vertical/revision-13/VerticalOrientation-13.txt
+# This file should be in a sub-directory "vertical" immediately below the
+# directory containing the other Unicode data files.
+#
+#
+# (2) Run this tool using a command line of the form
+#
+# perl genUnicodePropertyData.pl \
+# /path/to/harfbuzz/src \
+# /path/to/icu/common/unicode \
+# /path/to/UCD-directory
+#
+# This will generate (or overwrite!) the files

+# nsUnicodePropertyData.cpp
