"""
Export the compiled AssetRegistry contract's ABI to a plain JSON file, so the
separate web3.py script (interact.py, one level up) can load it. Ape already
knows the ABI internally, from compiling; this just writes it out in a format
a different library can read. Same idea as Week 4's get_abi.py, just pointed
at a different contract and a different output location (see the comment on
output_path below for why the location is different this time).

Run it once, right after deploying with scripts/deploy.py, and again any time
you change AssetRegistry.sol and redeploy:

    ape run get_abi --network <your-testnet-network-choice>
