+> Robolinux is a user-friendly and intuitive operating system based on the
+> latest long term support release of Ubuntu. One of the project's more
+> interesting features is the availability of a pre-configured virtual machine
+> support pack with Windows XP or Windows 7 - a VirtualBox setup which allows
+> the user to install and run the Windows operating system seamlessly alongside
+> Robolinux. This is an optional add-on that must be downloaded from the
+> project's online store.
