   * \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
