People using olpc-os-builder may make this analysis easier in future
if they make it a habit to tag and push for each published build, and
publish the repository with the build.

http://dev.laptop.org/git/users/quozl/olpc-firmware.git/tree/releaseme
is an example of this practice for firmware releases, see the last
section of the file.  It assumes that the default push repository is
the place to publish the tags.
