-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, --brain-params=l,p Use seed length 'l' and hash preset 'p' for
                       brainwallet input
-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)
-e, --echo-passphrase  Print passphrase to screen when typing it
-f, --tx-fee=        f Transaction fee, as a decimal {cu} amount or as
                       {fu} (an integer followed by {fl}).
                       See FEE SPECIFICATION below.  If omitted, fee will be
                       calculated using network fee estimation.
-g, --tx-gas=        g Specify start gas amount in Wei (ETH only)
-H, --hidden-incog-input-params=f,o  Read hidden incognito data from file
                      'f' at offset 'o' (comma-separated)
-i, --in-fmt=        f Input is from wallet format 'f' (see FMT CODES below)
-I, --inputs=        i Specify transaction inputs (comma-separated list of
                       MMGen IDs or coin addresses).  Note that ALL unspent
                       outputs associated with each address will be included.
-l, --seed-len=      l Specify wallet seed length of 'l' bits. This option
                       is required only for brainwallet and incognito inputs
                       with non-standard (< {g.seed_len}-bit) seed lengths.
-k, --keys-from-file=f Provide additional keys for non-{pnm} addresses
-K, --key-generator= m Use method 'm' for public key generation
                       Options: {kgs}
                       (default: {kg})
-L, --locktime=      t Lock time (block height or unix seconds) (default: 0)
-m, --minconf=n        Minimum number of confirmations required to spend
                       outputs (default: 1)
-M, --mmgen-keys-from-file=f Provide keys for {pnm} addresses in a key-
                       address file (output of '{pnl}-keygen'). Permits
                       online signing without an {pnm} seed source. The
                       key-address file is also used to verify {pnm}-to-{cu}
                       mappings, so the user should record its checksum.
-O, --old-incog-fmt    Specify old-format incognito input
-p, --hash-preset=   p Use the scrypt hash parameters defined by preset 'p'
                       for password hashing (default: '{g.hash_preset}')
-P, --passwd-file=   f Get {pnm} wallet passphrase from file 'f'
-r, --rbf              Make transaction BIP 125 (replace-by-fee) replaceable
-q, --quiet            Suppress warnings; overwrite files without prompting
-u, --subseeds=      n The number of subseed pairs to scan for (default: {ss},
                       maximum: {ss_max}). Only the default or first supplied
                       wallet is scanned for subseeds.
-v, --verbose          Produce more verbose output
-V, --vsize-adj=     f Adjust transaction's estimated vsize by factor 'f'
-y, --yes              Answer 'yes' to prompts, suppress non-essential output
-z, --show-hash-presets Show information on available hash presets
