    20  * \brief Switches for excluding parts of ICU library code modules.

    21  *

    22  * Allows to build partial, smaller libraries for special purposes.

    23  * By default, all modules are built.

    24  * The switches are fairly coarse, controlling large modules.

    25  * Basic services cannot be turned off.

    31  * \def UCONFIG_ONLY_COLLATION

    32  * This switch turns off modules that are not needed for collation.

    33  *

    34  * It does not turn off legacy conversion because that is necessary

    35  * for ICU to work on EBCDIC platforms (for the default converter).

    36  * If you want "only collation" and do not build for EBCDIC,

    37  * then you can #define UCONFIG_NO_LEGACY_CONVERSION 1 as well.
