+# 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.
+#
+# Note that for most properties, we now rely on ICU; this tool and the tables
+# it generates are used only for a couple of properties not readily exposed
+# via ICU APIs.
+#
+# To regenerate the tables in nsUnicodePropertyData.cpp:
+#
+# (1) Download the current Unicode data files from
+#
+#         https://www.unicode.org/Public/UNIDATA/
+#
+#     NB: not all the files are actually needed; currently, we require
+#       - UnicodeData.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
+#        https://www.unicode.org/Public/security/latest/IdentifierStatus.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-17:
+#        https://www.unicode.org/Public/vertical/revision-17/VerticalOrientation-17.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      \
