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