      3 # A script that generates an ICU data file containing just timezone rules data.
      4 # The file can be used to provide time zone rules updates for compatible
      5 # devices. Note: Only the rules are contained and new timezones will not have
      6 # the translations.
      7 #
      8 # Usage:
      9 # ./createIcuUpdateResources.sh <tzdata tar.gz file> <ICU version>
     10 #
     11 # e.g.
     12 # ./createIcuUpdateResources.sh ~/Downloads/tzdata2015b.tar.gz 55
     13 #
     14 # After execution the file is generated.
