Description:

The daemon receives SCSI commands from kernel module and processes
them, passing the requested data back to the kernel.

Daemon implements the actual virtual device; one instance per each
device registered by kernel module. It uses libMirage, an image
access library that is part of userspace-cdemu suite, for the image
access (e.g. sector reading).

Daemon is controlled through methods that are exposed via D-BUS. It
is written in C and based on GLib (and thus GObjects), but being
controlled over D-BUS, it allows for different clients written in
different languages.
