Hi Eric,

Nice work!  Do you ever sleep? ;-)

One of the big things I wanted to push for with 2.0 was consistency  
between
the options and builtins, particularly where something was possible  
with one
but not the other.  In respect of that mantra, --debugfile is the  
right option.
Since we don't want to break backwards compatibility so gratuitously,  
lets
continue to support -o and --error-output too, but perhaps give a  
deprecation
warning for the next several releases.

Ooo!  Sexy... yes that would be fantastic :-D

Cheers,
