/**
 * <B>INTERFACE TO NETSCAPE COMMUNICATOR PLUGINS (NEW C++ API).</B>
 *
 * <P>This supersedes the old plugin API (npapi.h, npupp.h), and 
 * eliminates the need for glue files: npunix.c, npwin.cpp and npmac.cpp that
 * get linked with the plugin. You will however need to link with the "backward
 * adapter" (badapter.cpp) in order to allow your plugin to run in pre-5.0
 * browsers. 
 *
 * <P>See nsPlugin.idl for an overview of how this interface fits with the 
 * overall plugin architecture.

 * The nsIPlugin interface is the minimum interface plugin developers need to

 * for more specific plugin types, e.g. nsILiveConnectPlugin.
 *
 * The old NPP_New plugin operation is now subsumed by two operations:
 *
 * CreateInstance -- called once, after the plugin instance is created. This 
 * method is used to initialize the new plugin instance (although the actual
 * plugin instance object will be created by the plugin manager).
 *
 * nsIPluginInstance::Start -- called when the plugin instance is to be
 * started. This happens in two circumstances: (1) after the plugin instance
 * is first initialized, and (2) after a plugin instance is returned to
 * (e.g. by going back in the window history) after previously being stopped
 * by the Stop method.
