+      This option group includes functions for reading and writing
+      messages to and from STREAMS.  The STREAMS interface provides a
+      uniform mechanism for implementing networking services and other
+      character-based I/O.  (STREAMS are not to be confused with
+      <stdio.h> FILE objects, also called 'streams'.)
