/**
libisoburn is a frontend for libraries libburn and libisofs which enables
creation and expansion of ISO-9660 filesystems on all CD/DVD media supported
by libburn. This includes media like DVD+RW, which do not support multi-session
management on media level and even plain disk files or block devices.
The price for that is thorough specialization on data files in ISO-9660
filesystem images. So libisoburn is not suitable for audio (CD-DA) or any
other CD layout which does not entirely consist of ISO-9660 sessions.
The priciple of this frontend is that you may use any call of libisofs or
libburn unless it has a isoburn_*() wrapper listed in the following function
documentation.
E.g. call isoburn_initialize() rather than iso_init(); burn_initialize()
and call isoburn_drive_scan_and_grab() rather than burn_drive_scan_and_grab().
But you may call burn_disc_get_profile() directly if you want to display
the media type.
>>>
>>> Take into respect Vreixo's (mandatory ?) shortcuts which are to come
>>>
The usage model is like with libburn: the target is a "media" in a "drive".
The wrappers will transparently provide the necessary emulations which
are appropriate for particular target "drives".
