+<p>A device driver is a program that controls a particular type of device
+that is attached to a base port. Writing a device driver requires an in-depth
+understanding of how the hardware and the software of a given platform function.
+The Device Driver writing guide tells you what you need and how to create
+a device driver.</p>
