# Support arguments (this recommend but not required):
# -f <file> Execute file on host, print the result and exit
# -c <command> [Not recommended to use] Execute command on host, print the result and exit
# -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 <HOME path> HOME path. Will be $HOME on the host.
# -X <XDG path> XDG_* path (https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html)
