+ * PluginWrapper is a simple base class for adapter plugins.  It takes
+ * a pointer to a "to be wrapped" Vamp plugin on construction, and
+ * provides implementations of all the Vamp plugin methods that simply
+ * delegate through to the wrapped plugin.  A subclass can therefore
+ * override only the methods that are meaningful for the particular
+ * adapter.
+ *
+ * \note This class was introduced in version 1.1 of the Vamp plugin SDK.
