to reseal a block. SET is one of:
none - never reseal on new transactions;
own - reseal only on a new local transaction;
ext - reseal only on a new external transaction;
all - reseal on all new transactions [default: all].
--tx-gas-limit GAS Apply a limit of GAS as the maximum amount of gas
a single transaction may have for it to be mined.
--relay-set SET Set of transactions to relay. SET may be:
cheap - Relay any transaction in the queue (this
may include invalid transactions);
strict - Relay only executed transactions (this
guarantees we don't relay invalid transactions, but
means we relay nothing if not mining);
lenient - Same as strict when mining, and cheap
when not [default: cheap].
