        """Load `Microsoft PowerPoint` files using `Unstructured`.

        Works with both .ppt and .pptx files.
        You can run the loader in one of two modes: "single" and "elements".
        If you use "single" mode, the document will be returned as a single
        langchain Document object. If you use "elements" mode, the unstructured
        library will split the document into elements such as Title and NarrativeText.
        You can pass in additional unstructured kwargs after mode to apply
        different unstructured settings.

        Examples
        --------
        from langchain_community.document_loaders import UnstructuredPowerPointLoader

        loader = UnstructuredPowerPointLoader(
            "example.pptx", mode="elements", strategy="fast",
        )
        docs = loader.load()
