+	  This driver provides a filesystem based API that lets user mode
+	  programs implement a single-configuration USB device, including
+	  endpoint I/O and control requests that don't relate to enumeration.
+	  All endpoints, transfer speeds, and transfer types supported by
+	  the hardware are available, through read() and write() calls.
+
+	  Say "y" to link the driver statically, or "m" to build a
+	  dynamically linked module called "gadgetfs".
