# To build a version of ICU which uses a two data libraries #
# where the smaller one is loaded first, use OS390_STUBDATA. #
# USAGE OF THIS OPTION IS DEPRECATED. You should look into using #
# Link Pack Area (LPA), library lookaside facility (LLA) or other #
# z/OS options that enable page fault based loading of read-only #
# code/data instead of this option. #
# This option will be removed in a future version of ICU. #
