+# A script that generates an ICU data file containing just timezone rules data.
+# The file can be used to provide time zone rules updates for compatible
+# devices. Note: Only the rules are contained and new timezones will not have
+# the translations.
+#
+# Usage:
+# ./createIcuUpdateResources.sh <tzdata tar.gz file> <ICU version>
+#
+# e.g.
+# ./createIcuUpdateResources.sh ~/Downloads/tzdata2015b.tar.gz 55
+#
+# After execution the file is generated.
