-h, --help            Print this help message
--, --longhelp        Print help message for long options (common options)
-a, --tx-fee-adj=  f  Adjust transaction fee by factor 'f' (see below)
-B, --no-blank        Don't blank screen before displaying unspent outputs
-c, --comment-file=f  Source the transaction's comment from file 'f'
-C, --tx-confs=    c  Desired number of confirmations (default: {g.tx_confs})
-d, --outdir=      d  Specify an alternate directory 'd' for output
-D, --contract-data=D Path to hex-encoded contract data (ETH only)

                      {fe_all}.  Default: {fe_dfl!r}
-f, --tx-fee=      f  Transaction fee, as a decimal {cu} amount or as

                      See FEE SPECIFICATION below.  If omitted, fee will be
                      calculated using network fee estimation.

-i, --info            Display unspent outputs and exit
-I, --inputs=      i  Specify transaction inputs (comma-separated list of
