# This script is responsible for generating some of the Unicode tables used
# in this project. It's a little weird here since ucd-generate is itself
# used to build the tables used by some of its dependencies. However, most
# tables are generated only for use in tests and benchmarks.
#
# Usage is simple, first download the Unicode data:
#
#   $ mkdir ucd
#   $ cd ucd
#   $ curl -LO https://www.unicode.org/Public/zipped/14.0.0/UCD.zip
#   $ unzip UCD.zip
#
# And then run this script from the root of this repository by pointing it at
# the data directory downloaded above:
#
#   $ ./scripts/generate-unicode-tables path/to/ucd

if [ $# != 1 ]; then
    echo "Usage: $(basename "$0") <ucd-data-directory>" >&2
    exit 1
