+                        pstream_client.cpp
+===============================================================================
+  This is an example of a client that uses XML-RPC for C/C++
+  (Xmlrpc-c).
+
+  In particular, it uses the simple "packet stream" XML transport mechanism
+  instead of HTTP as specified by XML-RPC (so this is not an XML-RPC
+  client).
+
+  You have to supply as Standard Input a stream (TCP) socket whose other
+  end is hooked up to the RPC server.  The 'socket_exec' program is a
+  good way to arrange that.
+
+  The sample program pstream_server.cpp is compatible with this client.
+
+  Example:
+
+    $ socketexec -connect -remote_host=localhost -remote_port=8080 \
+        ./pstream_client
