    Provide useful information, important for bug reports.

    It comprises info about hosting operation system, pandas version,

    Parameters
    ----------
    as_json : str or bool, default False
        * If False, outputs info in a human readable form to the console.
        * If str, it will be considered as a path to a file.
          Info will be written to that file in JSON format.
        * If True, outputs info in JSON format to the console.

    Examples
    --------
    >>> pd.show_versions()  # doctest: +SKIP
    Your output may look something like this:
