--kernel-path|-K <arg> Specify a path to where bitstream and kernel files are (default: "/usr/local/bin")
--load-balance Change multipool strategy from failover to efficiency based balance
--log|-l <arg> Interval in seconds between log output (default: 5)
--lowmem Minimise caching of shares for low memory applications
--monitor|-m <arg> Use custom pipe cmd for output messages
--net-delay Impose small delays in networking to not overload slow routers
--no-submit-stale Don't submit shares if they are detected as stale
