# Makefile for the scripts/ sub-directory

# Here, we can update the config.* scripts.
# If we're in CT_LIB_DIR, then CT_LIB_DIR == CT_TOP_DIR, and we can update those
# scripts for later inclusion mainline. If CT_LIB_DIR != CT_TOP_DIR, then those
# scripts are downloaded only for use in CT_TOP_DIR.
