+This program demonstrates an example of a source that reaches EOF after 5 lines.
+
+The stream adapter reads eagerly from the source: data is emitted as long as 
+select() on the source returns a non-null value. This means that all lines from
+the source in this example ar read at once. If you want the adapter to read
+at most one unit (message) from the source, you should probably be using a
+periodic timer directly, or use time mechanics as used by the other examples.
