/**

|
* <B>INTERFACE TO NETSCAPE COMMUNICATOR PLUGINS (NEW C++ API).</B>
|
|
*
|
|
* <P>This superscedes 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.h for an overview of how this interface fits with the
|
|
* overall plugin architecture.
