+ * KArtsWidget provides a simple way to treat Arts::Widget classes like
+ * native Qt widgets. Suppose you use Qt, and want to put an Arts::Widget
+ * type into a layout, you can do so using this code
+ *
+ * <pre>
+ *    Arts::Widget widget = ...get widget from somewhere...;
+ *    KArtsWidget *w = new KArtsWidget(widget, this);
+ *    layout->addWidget(w);
+ * </pre>
+ *
+ * In line 2 of the code, the "this" is the parent widget (which is usually
+ * this in Qt code).
+ *
+ * The KArtsWidget class keeps a reference to the content widget, so the
+ * content widget will not be freed until the KArtsWidget gets destroyed.
