anchor.diff:  
   With the above in our classpath, our command's help will now look like the following:
   
  -[source]
  +[listing]
   ----
   $ java -jar target/toolz-1.0.0-SNAPSHOT.jar rsync
   Missing argument: URI...
  
positive.code: 
  Default values will show up in help output automatically, no need to update your `OptionDescriptions.properties`
  
  [source]
  ----
  Usage: rsync [options] URI... URI
  
  
negative.code: In the above example we have no details in our help other than what can be generated from inspecting the code.  To add actual descriptions to our
  code we simply need to put an `OptionDescriptions.properties` in the same package as our class.
