# Makefile for the tools/ 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.

# Kludge: we have a step that is called 'tools', and thus we can not define a
# rule here that is named 'tools'. Naming it 'tools/' does not help either.
# Thus, prepend the top directory to have a single rule description. This is
# not as bad as it seems, because it is only refered to by teo rules in this
# file, but still it is a kludge...
