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.
