/* INTERFACE TO NETSCAPE COMMUNICATOR PLUGINS (NEW C++ API)
 *
 * This interface was an attempt to supersede npapi.h, npupp.h but it failed. It
 * would have eliminated the need for glue files: npunix.c, npwin.cpp and
 * npmac.cpp that get linked with the plugin.
 *
 * This is the master header file that includes most of the other headers
 * you'd have needed to write a plugin.
