// Netscape plugins are normally built at separate DLLs that are loaded by the

// this interface use the same Netscape Plugin API as DLL-based plugins.
// See https://developer.mozilla.org/En/Gecko_Plugin_API_Reference for complete
// documentation on how to use the Netscape Plugin API.

// This class provides attribute information and entry point functions for a
