and kills a few lines of code :)

Hey @caitp looks like you're doing some interesting stuff :)

Hmm, I'm not sure that I agree this is all that helpful, but what the heck, I'll take it

@caitp Well yea, as long as you use grunt tasks that have "grunt-*" in the name, you don't have to do anything. If you have tasks that follow a different pattern, you can specify it as well :)

@PascalPrecht, cool stuff :)
