I wan't to return a specific error message (internaly in Runrev), I wrote  
complex commands, who call a lot of subcommands and functions, and when an  
error is uncountered, I wan't to return it. The advantage is to permit to  
the developers to understand why there is an error. And this permit to the  
software to manage these errors. (For exemple, you call a command
in a try structure, and you can manage this error with catch).
