+/**
+ * 
+ * When two applications communicate with each other using a messaging system they first need to
+ * establish a communication channel that will carry the data. Message Channel decouples Message
+ * producers and consumers.
+ * <p>
+ * The sending application doesn't necessarily know what particular application will end up
+ * retrieving it, but it can be assured that the application that retrieves the information is
+ * interested in that information. This is because the messaging system has different Message
+ * Channels for different types of information the applications want to communicate. When an
+ * application sends information, it doesn't randomly add the information to any channel available;
+ * it adds it to a channel whose specific purpose is to communicate that sort of information.
+ * Likewise, an application that wants to receive particular information doesn't pull info off some
+ * random channel; it selects what channel to get information from based on what type of information
+ * it wants.
+ * <p>
+ * In this example we use Apache Camel to establish two different Message Channels. The first one
+ * reads from standard input and delivers messages to Direct endpoint. The second Message Channel is
+ * established from the Direct component to console output. No actual messages are sent, only the
+ * established routes are printed to standard output.
