It is a tape loader. It loads post installed operating system tapes and decompresses them into an automatically formatted drive. The tapes include the extensible firmware interface, the main system, and a recovery system. The recovery system is there in case you need permissions references or just a way to boot into a system you can fix system killers like broken .profile or .bash_rc.

After the system is loaded it runs a set of customizations including building Debian packages for the smooth running of the included applications also installed from the script. The system is tuned for content creators, for story telling in particular with over 40 applications from their most up to date sources.
