+This example demonstrates a query system reading from a file stream.
+
+gen_feed.py creates the file stream by replacing its contents
+every second, checking first if the GS-lite instance has finished
+processing the file.
+
+The source file is in gdat format, use
+  ../../bin/gdat2ascii example.gdat to see its contents
+
+Additional features demonstrated:
+  - a reference to an interface set in example.gsql
+  - the runall script starts up query system, note the use of gsprintconsole
+    to start processing
+  - the killall script ensures that gsprintconsole and gen_feed.py instances
+    are stopped.
