+ * \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
