> Has several different ways for reporting errors:
>  
>  # Couldn't
>  # Can't
>  # Could not
>  # Failed to
>  # Unable to
>  # Other
>  
> I think "Failed to" is the best verbage.  Contractions are hard for 
> non-native English speaking folks.  "Failed" is to the point. and more likely 
> to grep logs for 'fail' than I am 'unable' or 'could not'.
