 ## Return values
-Runnable uses another gems called ```Publisher```. It allow Runnable to fire 
-events that can be processed or ignored. When a command ends its execution, 
-Runnable always fire and event: ```:finish``` if commands finalized in a correct way 
-or ```:fail``` if an error ocurred. In case something went wrong and a ```:fail``` 
-events was fired, Runnable also provide an array containing the command return 
-value as the parameter of a SystemCallError exception and optionally others 
-exceptions ocurred at runtime.

 ## Custom exceptions
 As we saw in previous chapter, if a command execution does not ends 
 succesfully, Runnable fires a ```:fail``` event whit an exceptions array. We can
