+	<longdescription>
+		The CuraEngine is a C++ console application for 3D printing GCode generation.
+		It has been made as a better and faster alternative to the old Skeinforge engine.
+
+		This is just a console application for GCode generation.
+		For a full graphical application look at Cura which is the graphical frontend for CuraEngine.
+
+		The CuraEngine can be used seperately or in other applications. Feel free to add it to your application.
