+	  The Spice project aims to provide a complete open source
+	  solution for interaction with virtualized desktop devices.
+	  The Spice project deals with both the virtualized devices
+	  and the front-end. Interaction between front-end and
+	  back-end is done using VD-Interfaces.
+
+	  This package implements the server-part of Spice.
