| * |
| * Miscellaneous switches: |
| * |
| * A number of macros affect a variety of minor aspects of ICU. |
| * Most of them used to be defined elsewhere (e.g., in utypes.h or platform.h) |
| * and moved here to make them easier to find. |
| * |
| * Switches for excluding parts of ICU library code modules: |
| * |
| * Changing these macros allows building 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. |
