VirtualBox Scripts is a set of scripts for VirtualBox being written by Ben P. Dorsi-Todaro. It was initially inspired when he tried to install Mac OSX on VirtualBox and realized the writers of a tutorial didn't offer an easy solution for people, and required people to copy and paste commands.
The primary scripts help install Mac OSX on VirtualBox.
