+	  This is a video4linux driver for the Cisco PCIe Cobalt card.
+
+	  This board is sadly not available outside of Cisco, but it is
+	  very useful as an example of a real driver that uses all the
+	  latest frameworks and APIs.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called cobalt.
