30              tax: "CONFIG_GROUP:KEY=VALUE"
31
32       -t, --timeout TIMEOUT
33              global timeout for the execution of the command. Command is  in‐

42       --key KEY
43              user private key.
44
45       -4     forces Gfal2 to use IPv4 addresses only. (Option valid only  for
46              GridFTP protocol)
47
48       -6     forces  Gfal2 to use IPv6 addresses only. (Option valid only for
49              GridFTP protocol)
