Why?
Default configuration file will provide the same values that are currently 
hardcoded into dpkg-cross, so ease of usage will not suffer. We may even 
implement "include" statement for config file, and split such "base" 
setting into a separate file. By the way, user-provided config file will 
not replace system config file in this case, but will just be included 
from there.

But we will get great advantages:
- - it will be 100% clear what variables are being set, and what values they 
get. No longer (citing your message) "nobudy really know which ones are 
defined".
- - dpkg-cross code itself will become cleaner.


I just tried to implement 'unset' feature, and disliked the result. I 
really want to unify variable setting first. I probably will try to do 
that, and show you the result (without committing anything). I hope you'll 
like it :).
