  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.

  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.
