Awesome!

Sorry for the radio silence here. I was waiting for the changes to be
merged into oe-core, but it still hasn't happened yet.

I am going to send out a V4 which just builds everything but doesn't
add any run functionality. Hopefully then when I can add the run
functionality the build work is already reviewed and good to go.

I have a look at your branch that did this and I remember that it
looked pretty good, but there were a few changes that I think should
be made. I want to wait until that is all finalised until I spend too
much time on it though.

Thanks,

Alistair
