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