+    This API is used to facilitate binding code written in C to script
+    objects.  The API in this header does not assume the presence of a
+    user agent.  That is, it can be used to bind C code to scripting
+    environments outside of the context of a user agent.
+    
+    However, the normal use of the this API is in the context of a
+    scripting environment running in a browser or other user agent.
+    In particular it is used to support the extended Netscape
+    script-ability API for plugins (NP-SAP).  NP-SAP is an extension
+    of the Netscape plugin API.  As such we have adopted the use of
+    the "NP" prefix for this API.
+
+    The following NP{N|P}Variables were added to the Netscape plugin
+    API (in npapi.h):
+
+    NPNVWindowNPObject
+    NPNVPluginElementNPObject
+    NPPVpluginScriptableNPObject
+
+    These variables are exposed through NPN_GetValue() and
+    NPP_GetValue() (respectively) and are used to establish the
+    initial binding between the user agent and native code.  The DOM
+    objects in the user agent can be examined and manipulated using
+    the NPN_ functions that operate on NPObjects described in this
+    header.
+
+    To the extent possible the assumptions about the scripting
+    language used by the scripting environment have been minimized.
