class BSDDBCookieJar(CookieJar):
    """CookieJar based on a BSDDB database, using the standard bsddb module.

    You should use CreateBSDDBCookieJar instead of the constructor, unless you
    know what you're doing.

    Note that session cookies ARE stored in the database (marked as session
    cookies), and will be written to disk if the database is file-based.  In
    order to clear session cookies at the end of a session, you must call
    .clear_session_cookies().

    Call the .close() method after you've finished using an instance of this
    class.
