The bundle/ directory is just for smaller Python packages that are automatically included

 * <kbd>kronos</kbd> 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 It's no longer maintained though.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.
