--  <description>
--  Note that this package is currently not supported under Win32 systems.
--
--  Together with Gtk_Socket, Gtk_Plug provides the ability to embed widgets
--  from one process into another process in a fashion that is transparent to
--  the user. One process creates a Gtk_Socket widget and, passes the XID of
--  that widgets window to the other process, which then creates a Gtk_Plug
--  window with that XID.
--  Any widgets contained in the Gtk_Plug then will appear inside the first
--  applications window.
