Ah, I was wondering about multiple outputs (if we actually mean the same 
thing here: one source tree, multiple packages, e.g. binary, dev, doc) as 
this seems to be standard practice in packaging nowadays. I am looking 
forward to 14.10, then... :)

BTW, it is currently a common limitation (e.g. in debian) that although one 
can have multiple versions of a binary package installed, there can be only 
one version of the development package. I think NixOS should be able to 
easily avoid such a restriction, and this would be a very strong selling 
point!

Cheers
Ben
