# This script copies (changed) generated UCD files

#   * INTO <unicodetools_repo>/unicodetools/data/dev
#
# This should be run after running UCD.Main to generate files after making changes to certain data
# files (e.g. PropsList.txt) which cause UCD.Main to generate derived files.
#
# Files in the tree that start with "ZZZ-UNCHANGED-" will be skipped.
