+%description
+This package provides the following drivers:
+
+Driver (vboxguest) for the Virtual Box Guest PCI device used in Virtual Box
+virtual machines. Enabling this driver will add support for Virtual Box Guest
+integration features such as copy-and-paste, seamless mode and OpenGL
+pass-through.
+
+Driver (vboxfs) required to mount folders exported by the Virtual Box host to
+be shared with guests.
+
+KMS driver (vboxvideo) for the virtual Graphics Card used in Virtual Box
+virtual machines.
