invoking the command with 'gen_key' and then creating and encrypting the
wallet using the -P (--passwd-file) option:
$ mmgen-walletconv -r0 -q -iwords -d{wallet_dir} -p1 -P{tx_dir}/{key_fn} -Llabel
$ mmgen-walletconv -r0 -q -iwords -d{wallet_dir} -p1 -P/mnt/tx/autosign.key -Llabel
Note that the hash preset must be '1'. Multiple wallets are permissible.
