    This class has several optional parameters for initialisation, which may
    be used to influence the behaviour of the object:

    The optional parameter `progress` is a CdromProgress() subclass, which will
    ask for the correct cdrom, etc. If not specified or None, a CdromProgress()
    object will be used.

    The optional parameter `mountpoint` may be used to specify an alternative
    mountpoint.

    If the optional parameter `nomount` is True, the cdroms will not be
    mounted. This is the default behaviour.
