  * The audio code calls run() on an instance that has been passed to
  * it, and assumes that the passing code has already initialised the
  * plugin, connected its inputs and outputs and so on, and that there
  * is an understanding in place about the sizes of the buffers in use
  * by the plugin.  All of this depends on the subclass implementation.
+ *
+ * The PluginInstance base class includes additional abstract methods
+ * which the subclass of RealTimePluginInstance must implement.
