# ./maketx.sh input-file output-file
#
# input-file cointains data to build up the input: UTXO and sender addresses 
# TXID VOUT (ADDRESS)
#
# output-file cointains data to build up the output: destination addresses and amount
# ADDRESS AMOUNT

# you first need run the Bitcoin Core (bitcoind) in order to use this script!!! 
# the private keys to the sender addresses must be in your wallet.dat!
# you don't need to be online to create and sign the transaction, but you have to be to send it
