liebert - Driver for Liebert contact-closure UPS equipment

       This driver does not yet support shutdowns by raising DTR. Be aware that shutdowns are not possible with
       the stock contact-closure cable. You may have to build another cable with DTR connected through to the
       UPS for it to work.

       There is no way for this driver to detect the hardware or cable. It will start up successfully even if no
       UPS is present. This is a fundamental limitation of any contact-closure driver.

       This driver does not support any extra settings in the ups.conf(5).
