I ported bits of that to narcissus to generate a manifest, have a look at:

http://git.angstrom-distribution.org/cgi-bin/cgit.cgi/narcissus/tree/scripts/extract-metadata.sh
http://git.angstrom-distribution.org/cgi-bin/cgit.cgi/narcissus/tree/scripts/assemble-image.sh#n275

Narcissus will generate a html page that looks like the manifest we use internally in TI to get things approved by the opensource reviewboard, so if things look strange, that's why :)

The angstrom autobuilders log a subset of testlab into a git repo: http://git.angstrom-distribution.org/cgi-bin/cgit.cgi/testlab/log/?h=yocto
