which enables creation and expansion of ISO-9660 filesystems on all media and file types supported by libburn. It implements the API and command interpreter of program xorriso, and installs this program as small dynamically linked binary. xorriso is suitable for incremental data backup and for production of bootable ISO 9660 images. A statically linked version is available as GNU xorriso.
