One problem (or problematic restriction) I see is that the script relies on
the new buildstats format introduced by PATCH 2/3 in this patchset, making
the script incompatible with older buildstats and not being able to render
them.

Another problem for me is the dependency on datamash which I wasn't able to
find for my distro (openSUSE Leap 42.1). How hard would it be to ditch the
dependency on datamash?


Thanks,
