# Tools and build scripts for updating data originating from CLDR ## CLDR test data The ant [build.xml](build.xml) file takes care of copying some CLDR test data directories to both the ICU4C and ICU4J source trees. To add more directories to the list, modify the `cldrTestData` fileset. ## cldr-to-icu The cldr-to-icu directory contains tools to convert from CLDR's XML data to ICU resource files. See [cldr-to-icu/README.txt](cldr-to-icu/README.txt) and [cldr-icu-readme.txt](../../icu4c/source/data/cldr-icu-readme.txt) for more information.
