the build origin of the current angstrom BB images?

regarding these pre-built angstrom images for BB:

http://www.angstrom-distribution.org/demo/beagleboard/

does someone know the precise build process that was used to create
them. i'm *guessing* that the stable image is based on the
stable/2009 branch of OE, but it's not clear what bitbake image target
was used. it would be nice to be able to match the image with its
build recipe, as a way for newbies to try to reproduce the pre-built
stuff. thanks.

i believe the recipe you're looking for is beagleboard-demo-image
All the valid images are in recipes/images
