# This script takes indexes in the CIFF format (https://github.com/osirrc/ciff)
# and builds a PISA-compatible binary (uncompressed) index.
#
# First, the script will look in the $INPUT and $OUTPUT directories for the .ciff files.
# If they are not found, it will fall back to downloading them.
# This way, you can run it multiple times without spurious downloads,
# or provide your own CIFF index.
