* 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.
