 * Revision 1.5  2003/04/14 08:41:00  gareth
 * Xlat now works under linux - Big thanks to Neil Graham (I no longer have to find a windows box). Still slight problems working with glibc before 2.2.4 (If you mess up the parameters it seg faults due to handling of wprintf)
 *
 * Revision 1.4  2002/12/17 17:39:09  tng
 * Xlat: generate icu message file with array format as default.
 *
 * Revision 1.3  2002/12/12 23:40:38  peiyongz
 * normlize locale string.
 *
 * Revision 1.2  2002/11/05 21:15:16  peiyongz
 * generate correct <locale>.txt file
 *
 * Revision 1.1  2002/09/30 22:09:28  peiyongz
 * To generate icu resource file (in text) for error message.
