/*!
 * \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

 * If you want "only collation" and do not build for EBCDIC,
 * then you can define UCONFIG_NO_LEGACY_CONVERSION 1 as well.
