# cli.sh — Bitcoin transaction / block analyzer CLI
#
# Usage:
#   ./cli.sh <fixture.json>                    Single-transaction mode
#   ./cli.sh --block <blk.dat> <rev.dat> <xor.dat>   Block mode
#
# Transaction mode:
#   - Reads the fixture JSON (raw_tx + prevouts)
#   - Parses the transaction and computes all fields
#   - Writes JSON report to out/<txid>.json
#   - Prints JSON report to stdout
#   - Exits 0 on success, 1 on error
#
# Block mode:
#   - Reads blk*.dat, rev*.dat, and xor.dat
#   - Parses all blocks and transactions
#   - Writes JSON report per block to out/<block_hash>.json
#   - Exits 0 on success, 1 on error
