        You can set the `seek` parameter to read the file starting from a
        specific position.

        You can set the `limit` parameter to read the file up to specific
        position.

        Finally, you can change the number of bytes read at once by setting the
        `block_size` parameter.

    This will serve index files (by default ``index.html``), or set
    ``index_page=None`` to disable this.  If you set
    ``hide_index_with_redirect=True`` (it defaults to False) then
    requests to, e.g., ``/index.html`` will be redirected to ``/``.

    To customize `FileApp` instances creation (which is what actually
    serves the responses), override the `make_fileapp` method.
