510.IP
511Fee rates (in BTC/kvB) smaller than this are considered zero fee for
512transaction creation (default: 0.00001)

526.HP
527\fB\-wallet=\fR<path>
528.IP
529Specify wallet path to load at startup. Can be used multiple times to
530load multiple wallets. Path is to a directory containing wallet
531data and log files. If the path is not absolute, it is
532interpreted relative to <walletdir>. This only loads existing
533wallets and does not create new ones. For backwards compatibility
534this also accepts names of existing top\-level data files in
535<walletdir>.

547.IP
548Execute command when a wallet transaction changes. %s in cmd is replaced
549by TxID, %w is replaced by wallet name, %b is replaced by the
550hash of the block including the transaction (set to 'unconfirmed'
551if the transaction is not included) and %h is replaced by the
552block height (\fB\-1\fR if not included). %w is not currently
553implemented on windows. On systems where %w is supported, it
554should NOT be quoted because this would break shell escaping used
555to invoke the command.
