# -C <command in base64> Execute command on host, print the result and exit
# -v <level> Verbose mode: 1 - verbose, 2 - super verbose
# -e <NAME=B64> -e ... Environement variables (B64 is base64 encoded string)
# -b <BASE64> -b ... Base64 encoded bash command
# -H <homepath> Home path. Will be $HOME on the host.
