+/**
+ * Implements the "WordCount" program that computes a simple word
occurrence histogram over text files in a streaming
+ * fashion. The program is constructed as a regular {@link StormTopology}
and submitted to Flink for execution in the
+ * same way as to a Storm {@link LocalCluster}.
+ *
+ * This example shows how to run program directly within Java, thus it
cannot be used to submit a {@link StormTopology}
+ * via Flink command line clients (ie, bin/flink).
+ *
+ * <p>
+ * The input is a plain text file with lines separated by newline
characters.
+ *
+ * <p>
+ * Usage: <code>WordCount <text path> <result path></code><br>
+ * If no parameters are provided, the program is run with default data
from {@link WordCountData}.
+ *
+ * <p>
+ * This example shows how to:
+ * <ul>
+ * <li>run a regular Storm program locally on Flink
+ * </ul>

Why is it necessary to sleep in the examples? Isn't there a way to submit
the topology in a blocking way?
