+<section><title>Description</title> <p> <filepath>TAndRClasses</filepath> shows
+a typical ‘T’ class and a typical ‘R’ class. </p> <p>The ‘T’ type is a value
+type, owning no external object. </p> <p>The ‘R’ type is a resource type;
+typically this is proxy for an object owned elsewhere. In practice, the 'R'
+type is a handle to a resource owned and managed by the Kernel. </p> <p>In
+this example, the ‘R’ class derives from the standard Symbian platform handle
+class <codeph>RTimer</codeph>. </p> </section>
