[yocto] (How) did you script bitbake/set up nightly builds?

[Alan Martinovic]

Thanks Ross
this is what more or less what I'm doing.
What I haven't found a way to do from python is making modifications from
the initialized build directory.

I'd like to do that to change things in conf/local.conf.
For example generate DISTRO_VERSION from git describe --tags

That is something that needs to happen in between
. oe-init-build-env  and bitbake foo
