+  Example program to output N channels of audio
+  data over an ethernet socket connection.
+
+  by Gary P. Scavone, 2000
+
+  This program is currently written to load
+  a WAV file for streaming.  However, it is
+  simple to replace the instance of WavWvIn
+  with any other WvIn subclass.
+
+  The class StrmWvOut first attempts to
+  establish a socket connection to a socket
+  server running on port 2005.  Thus, this
+  program needs to be started after the
+  streaming server.
