   You can dump the queue to the terminal using `net.openhft.chronicle.queue.main.DumpMain` or `net.openhft.chronicle.queue.ChronicleReaderMain`. `DumpMain` performs a simple dump to the terminal while `ChronicleReaderMain` handles more complex operations, e.g. tailing a queue. They can both be run from the command line in a number of ways described below.

   If you have a project pom file that includes the Chronicle-Queue artifact, you can read a `cq4` file with the following command:
   
   [source, shell script]
  
positive.code:         readingDocument().isPresent();
  ....
  
  ===== *6. Restartable tailers*
  
  It can be useful to have a tailer which continues from where it was up to on restart of the application.

  * *3. Reading from a queue using a tailer*
  
  Reading the queue follows the same pattern as writing, except there is a possibility there is not a message when you attempt to read it.
