def METHOD_NAME(key, value, setting=None, conf_file=_DEFAULT_CONF):
    """
    Set a new value for a specific configuration line.
    :param str key: The command or block to configure.
    :param str value: The command value or command of the block specified by the key parameter.
    :param str setting: The command value for the command specified by the value parameter.
    :param str conf_file: The logrotate configuration file.
    :return: A boolean representing whether all changes succeeded.
    :rtype: bool
    CLI Example:
    .. code-block:: bash
        salt '*' logrotate.set rotate 2
    Can also be used to set a single value inside a multiline configuration
    block. For instance, to change rotate in the following block:
    .. code-block:: text
        /var/log/wtmp {
            monthly
            create 0664 root root
            rotate 1
        }
    Use the following command:
    .. code-block:: bash
        salt '*' logrotate.set /var/log/wtmp rotate 2
    This module also has the ability to scan files inside an include directory,
    and make changes in the appropriate file.
