    Value of the MESSAGE argument will be used for the MESSAGE=
    field. MESSAGE must be a string and will be sent as UTF-8 to
    the journal.

    MESSAGE_ID can be given to uniquely identify the type of
    message. It must be a string or a uuid.UUID object.

    CODE_LINE, CODE_FILE, and CODE_FUNC can be specified to
    identify the caller. Unless at least on of the three is given,
    values are extracted from the stack frame of the caller of
    send(). CODE_FILE and CODE_FUNC must be strings, CODE_LINE
    must be an integer.

    Additional fields for the journal entry can only be specified
    as keyword arguments. The payload can be either a string or
    bytes. A string will be sent as UTF-8, and bytes will be sent
    as-is to the journal.

    Other useful fields include PRIORITY, SYSLOG_FACILITY,
    SYSLOG_IDENTIFIER, SYSLOG_PID.
