* \file
* \brief Switches for excluding parts of ICU library code modules.
*
* Allows to build partial, smaller libraries for special purposes.
* By default, all modules are built.
* The switches are fairly coarse, controlling large modules.
* Basic services cannot be turned off.
*
* Building with any of these options does not guarantee that the
* ICU build process will completely work. It is recommended that
* the ICU libraries and data be built using the normal build.
* At that time you should remove the data used by those services.
* After building the ICU data library, you should rebuild the ICU
* libraries with these switches customized to your needs.
*
* @stable ICU 2.4

* then you can define UCONFIG_NO_LEGACY_CONVERSION 1 as well.
