18* This tool operates on ICU data (.dat package) files.
19* It takes one as input, or creates an empty one, and can remove, add, and
20* extract data pieces according to command-line options.
21* At the same time, it swaps each piece to a consistent set of platform
22* properties as desired.
23* Useful as an install-time tool for shipping only one flavor of ICU data
24* and preparing data files for the target platform.
25* Also for customizing ICU data (pruning, augmenting, replacing) and for
26* taking it apart.
27* Subsumes functionality and implementation code from
28* gencmn, decmn, and icuswap tools.
29* Will not work with data DLLs (shared libraries).
