+Framework</title><shortdesc>This section describes the device driver framework and how to use
+it to create a driver.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>It begins with an explanation of the main concepts and objects used in
+device drivers: the channel objects that implement their interfaces, and the
+factory objects that create these channels. This is followed by descriptions
+of how to communicate with hardware devices by handling their interrupts,
+and the platform security issues of which you need to be aware. </p>
+<p>The section ends by presenting the source code to a simple example device
+driver as a starting point for writing your own driver. </p>
