The bundle/ directory is just for smaller Python packages that are automatically included indebs/rpms/zips.

* kronos is used for job scheduling (basically cron within a Python process), a simpler wrapper around the `sched` module. It's no longer maintained though.

* `bundle/` also used to contain a fallback version python-requests for example. But that's now current enough in all distros, so unneeded as builtin module.
