Example implementation wrapper (extract_olm_emails.py)

#!/usr/bin/env python3

import argparse, sys

def main():
    parser = argparse.ArgumentParser()
    parser.add_argument("--olm", required=True, help="Path to OLM file")
    parser.add_argument("--output", help="Optional output file for unique addresses")
    args = parser.parse_args()

    # NOTE: In a real setup, import the library code from the cloned repo instead:
    # from olm_exporter import extract_addresses
    #
    # addresses = extract_addresses(args.olm)
    # For this template, just show the interface.
    addresses = set()  # placeholder

    if args.output:
        with open(args.output, "w", encoding="utf-8") as f:
            for addr in sorted(addresses):
                f.write(addr + "\n")
    else:
        for addr in sorted(addresses):
            print(addr)

if __name__ == "__main__":
    main()

(Replace the placeholder logic with the actual API calls from the cloned project.)
