    • -o, --url=URL == URL of mining server
    • -O, --userpass=U:P == username:password pair for mining server
    • -u, --user=USERNAME == username for mining server
    • -p, --pass=PASSWORD == password for mining server
      --cert=FILE == certificate for mining server using SSL
    • -x, --proxy=[PROTOCOL://]HOST[:PORT] == connect through a proxy
    • -t, --threads=N == number of miner threads (default: number of processors)
    • -r, --retries=N == number of times to retry if a network call fails (default: retry indefinitely)
    • -R, --retry-pause=N == time to pause between retries, in seconds (default: 30)
    • -T, --timeout=N timeout for long polling, in seconds (default: none)
    • -s, --scantime=N == upper bound on time spent scanning current work when long polling is unavailable, in seconds (default: 5)
