* \brief User-configurable settings
*
* Miscellaneous switches:
*
* A number of macros affect a variety of minor aspects of ICU.
* Most of them used to be defined elsewhere (e.g., in utypes.h or platform.h)
* and moved here to make them easier to find.
*
* Switches for excluding parts of ICU library code modules:
*
* Changing these macros allows building 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.
