def main():
    """
    Main function that serves as the entry point for the program.

    This function retrieves the argument specification using the `get_argument_spec` function and updates it with the `idrac_auth_params`.
    It then creates an `AnsibleModule` object with the updated argument specification, specifying the mutually exclusive arguments,
    required arguments if conditions are met, and setting `supports_check_mode` to `False`.

    The function then attempts to establish a connection with the iDRAC Redfish API using the `iDRACRedfishAPI` class.
    It retrieves the iDRAC firmware version using the `get_idrac_firmware_version` function and checks if it is less than or equal to '3.0'.
    If it is, the function exits with a message indicating that the iDRAC firmware version is not supported and sets `failed` to `True`.

    If the iDRAC firmware version is supported, the function creates a `LicenseType` object using the `license_operation` method of the
    `LicenseType` class and calls the `execute` method on the `license_obj` object, passing in the `module` object.

    If an `HTTPError` occurs, the function loads the error response as JSON, removes a specific key using a regular expression pattern,
    and exits with the error message, the filtered error information, and sets `failed` to `True`.

    If a `URLError` occurs, the function exits with the error message and sets `unreachable` to `True`.

    If any of the following errors occur: `SSLValidationError`, `ConnectionError`, `TypeError`, `ValueError`, or `OSError`, the function
    exits with the error message and sets `failed` to `True`.

    Parameters:
        None

    Returns:
