@petermetz @RafaelAPB I also added a quick message about the python dependency in the prerequisites of README.md. If you don't find it necessary I can remove it. Otherwise I think everything is done in this commit: e1626c4095f6dfb21497ddcfbcaadb6beff0162e. You should be able to cherry-pick and squash it.
