Well, QBS-87 turned out to be real easy so you can get stuck into this instead :-P

OK.

I could live without it if we had something like the profiles I proposed in my previous mail (sent that before reading your last mail so there's some overlap). Although I noticed that qt.core.version is hardcoded to "4.7.0" unless you set it explicitly in the config - I can see that tripping me up in the future once I've forgotten all about how this stuff works, so maybe a bit of magic is justified to protect the user from themselves.

Cheers,
